1Antitumor activities of human autologous cytokineinduced killer(CIK)cells against hepatocellular carcinoma cells in vitro and in vivo显示文摘AIM: To characterize the anticancer function of cytokine-induced killer cells (CIK) and develop an adoptiveimmunotherapy for the patients with primary hepatocellularcarcinoma (HCC), we evaluated the proliferation rate,phenotype and the antitumor activity of human CIK cellsfrom healthy donors and HCC patients in vitro and in vivo.METHODS: Peripheral blood mononuclear cells (PBMC) fronhealthy donors and patients with primary HCC were incubatedin vitro and induced into ClK cells in the presence of variouscytokines such as interferon-gamma (IFN-γ), interleukin-1(IL-1), IL-2, and monoclonal antibody (mAb) against CD3.The phenotype and characterization of CIK cells wereidentified by flow cytometric analysis. The cytotoxicity of CIKcells was determined by 51 Cr release assay.RESULTS: The CIK cells were shown to be a heterogeneouspopulation with different cellular phenotypes. Thepercentage of CD3+/CD56+ positive cells, the dominanteffector cells, in total CIK cells from healthy donors andHCC patients, significantly increased from 0.1-0.13 % at day0 to 19.0-20.5 % at day 21 incubation, which suggested thatthe CD3+ CD56+ positive cells proliferated faster than othercell populations of CIK cells in the protocol used in thisstudy. After 28 day in vitro incubation, the ClK cells frompatients with HCC and healthy donors increased by morethan 300-fold and 500-fold in proliferation cell number,respectively. CIK cells originated from HCC patientspossessed a higher in vitro antitumor cytotoxic activity onautologous HCC cells than the autologous lymphokine-activated killer (LAK) cells and PBMC cells. In in vivoanimal experiment, CIK cells had stronger effects on theinhibition of tumor growth in Balb/c nude mice bearing BEL-7402-producing tumor than LAK cells (mean inhibitory rate,84.7 % vs 52.8 %, P < 0.05) or PBMC (mean inhibitoryrate, 84.7% vs37.1%, P<0.01).CONCLUSION: Autologous CIK cells are of highly efficientcytotoxic effector cells against primary hepatocellularcarcinoma cells and might serve as an alternative adoptivetherapeutic strategy for HCC patients.Fu-Sheng Wang Ming-Xu Liu Bing Zhang Ming Shi Zhou-Yun Lei Wen-Bing Sun Qing-You Du Ju-Mei Chen,Division of Biological Engineering,Beijing Institute of Infectious Diseases,Beijing 100039,China Wen-Bing Sun,Department of Surgery,Beijing Hospital of Infectious Diseases,Beijing 100039,China 2002World Journal of Gastroenterology2002,8,3:108
22018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu 2018Science Bulletin2018,63,23:54
3Cold-chain food contamination as the possible origin of COVID-19 resurgence in Beijing显示文摘COVID-19,caused by SARS-CoV-2[1,2],has been contained in China through stringent non-pharmaceutical interventions.Border control and quarantine have effectively prevented the virus from being spread by infected travellers,but the risk of resurgence caused by other routes of introduction and transmission remains unclear,and current strategies to prevent resurgence could be flawed.Since July,SARS-CoV-2 RNA contaminations in frozen food imported from countries with ongoing epidemics have been reported in nine provinces in China[3,4].However,there is no robust evidence of COVID-19 outbreaks initiated by environmentto-human transmission.Here we add to evidence of such transmission by investigating the recent COVID-19 resurgence in Beijing.Xinghuo Pang Lili Ren Shuangsheng Wu Wentai Ma Jian Yang Lin Di Jie Li Yan Xiao Lu Kang Shichang Du Jing Du Jing Wang Gang Li Shuguang Zhai Lijuan Chen Wenxiong Zhou Shengjie Lai Lei Gao Yang Pan Quanyi Wang Mingkun Li Jianbin Wang Yanyi Huang Jianwei Wang COVID-19 Field Response Group COVID-19 Laboratory Testing Group 2020National Science Review2020,7,12:51

5Characterization of the receptor-binding domain(RBD)of 2019 novel coronavirus:implication for development of RBD protein as a viral attachment inhibitor and vaccine显示文摘The outbreak of Coronavirus Disease 2019(COVID-19)has posed a serious threat to global public health,calling for the development of safe and effective prophylactics and therapeutics against infection of its causative agent,severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),also known as 2019 novel coronavirus(2019-nCoV).The CoV spike(S)protein plays the most important roles in viral attachment,fusion and entry,and serves as a target for development of antibodies,entry inhibitors and vaccines.Here,we identified the receptor-binding domain(RBD)in SARS-CoV-2 S protein and found that the RBD protein bound strongly to human and bat angiotensin-converting enzyme 2(ACE2)receptors.SARS-CoV-2 RBD exhibited significantly higher binding affinity to ACE2 receptor than SARS-CoV RBD and could block the binding and,hence,attachment of SARS-CoV-2 RBD and SARS-CoV RBD to ACE2-expressing cells,thus inhibiting their infection to host cells.SARS-CoV RBD-specific antibodies could crossreact with SARS-CoV-2 RBD protein,and SARS-CoV RBD-induced antisera could cross-neutralize SARS-CoV-2,suggesting the potential to develop SARS-CoV RBD-based vaccines for prevention of SARS-CoV-2 and SARS-CoV infection.Wanbo Tai Lei He Xiujuan Zhang Jing Pu Denis Voronin Shibo Jiang Yusen Zhou Lanying Du 2020Cellular & Molecular Immunology2020,17,6:35
6Sleep and Cognitive Abnormalities in Acute Minor Thalamic Infarction显示文摘In order to characterize sleep and the cognitive patterns in patients with acute minor thalamic infarction(AMTI), we enrolled 27 patients with AMTI and 12 matched healthy individuals. Questionnaires about sleep and cognition as well as polysomnography(PSG) were performed on days 14 and 90 post-stroke. Compared to healthy controls, in patients with AMTI, hyposomnia was more prevalent; sleep architecture was disrupted as indicated by decreased sleep efficiency, increased sleep latency, and decreased non-rapid eye movement sleep stages 2 and 3;more sleep-related breathing disorders occurred; and cognitive functions were worse, especially memory. While sleep apnea and long-delay memory recovered to a large extent in the patients, other sleep and cognitive function deficit often persisted. Patients with AMTI are at an increased risk for hyposomnia, sleep structure disturbance,sleep apnea, and memory deficits. Although these abnormalities improved over time, the slow and incomplete improvement suggest that early management should be considered in these patients.Wei Wu Linyang Cui Ying Fu Qianqian Tian Lei Liu Xuan Zhang Ning Du Ying Chen Zhijun Qiu Yijun Song Fu-Dong Shi Rong Xue 2016Neuroscience Bulletin2016,32,4:28
7Breast cancer development and progression:Risk factors,cancer stem cells,signaling pathways,genomics,and molecular pathogenesis显示文摘As the most commonly occurring cancer in women worldwide,breast cancer poses a formidable public health challenge on a global scale.Breast cancer consists of a group of biologically and molecularly heterogeneous diseases originated from the breast.While the risk factors associated with this cancer varies with respect to other cancers,genetic predisposition,most notably mutations in BRCA1 or BRCA2 gene,is an important causative factor for this malignancy.Breast cancers can begin in different areas of the breast,such as the ducts,the lobules,or the tissue in between.Within the large group of diverse breast carcinomas,there are various denoted types of breast cancer based on their invasiveness relative to the primary tumor sites.It is important to distinguish between the various subtypes because they have different prognoses and treatment implications.As there are remarkable parallels between normal development and breast cancer progression at the molecular level,it has been postulated that breast cancer may be derived from mammary cancer stem cells.Normal breast development and mammary stem cells are regulated by several signaling pathways,such as estrogen receptors(ERs),HER2,and Wnt/b-catenin signaling pathways,which control stem cell proliferation,cell death,cell differentiation,and cell motility.Furthermore,emerging evidence indicates that epigenetic regulations and noncoding RNAs may play important roles in breast cancer development and may contribute to the heterogeneity and metastatic aspects of breast cancer,especially for triple-negative breast cancer.This review provides a comprehensive survey of the molecular,cellular and genetic aspects of breast cancer.Yixiao Feng Mia Spezia Shifeng Huang Chengfu Yuan Zongyue Zeng Linghuan Zhang Xiaojuan Ji Wei Liu Bo Huang Wenping Luo Bo Liu Yan Lei Scott Du Akhila Vuppalapati Hue H.Luu Rex C.Haydon Tong-Chuan He Guosheng Ren 2018Genes & Diseases2018,5,2:24
8Pattern and timing of late Cenozoic rapid exhumation and uplift of the Helan Mountain,China显示文摘The Helan Mountain, an intraplate deformation belt in the North China Craton, is located in the northern portion of the China North-South seismic belt, and at the northwestern margin of the Ordos Block. The Cenozoic deformation history of the Helan Mountain is characterized by extension along the eastern Helan Mountain fault (EHSF), resulting in the exhumation and uplift of the Helan Mountain, relative to the rifting of the adjacent Yinchuan Basin. Here we present new apatite fission track (AFT) data from several transects adjacent to the EHSF in the central and northern Helan Mountain. AFT ages from the northern Helan Mountain (Dawukou and Zhengyiguan transects) range from 10 Ma to 89 Ma, whereas AFT ages from the southern Helan Mountain (Suyukou transect) are greater than 71 Ma. The AFT data analysis reveals initiation of rapid uplift and exhumation of the Helan Mountain at 10–12 Ma. Additionally, a plot of the AFT ages versus their mean track length shows a distinctive 'boomerang' pattern indicating that the Helan Mountain experienced a discrete phase of accelerated exhumation beginning at 10-12 Ma. Spatially, AFT samples systematically increase in age away from the EHSF and are consistent with late Cenozoic exhumation that was slow in the southwestern Helan Mountain and rapid in the northeastern Helan Mountain, as well more rapid adjacent to the EHSF and slower away from the EHSF. Obviously, the spatial distribution of late Cenozoic exhumation indicates that normal faulting of the EHSF is related to southwestward tilting and rapid exhumation of the Helan Mountain beginning at 10–12 Ma. The uplift and exhumation of the Helan Mountain was a response to the intensive extension of the northwestern margin of the Ordos Block in the late Cenozoic; this occurred under a regional extensional stress field oriented NW-SE along the Yinchuan-Jilantai-Hetao and the Weihe-Shanxi graben systems adjacent to the Ordos Block.LIU JianHui ZHANG PeiZhen ZHENG DeWen WAN JinLin WANG WeiTao DU Peng LEI QiYun 2010Science China Earth Sciences2010,53,3:23
9Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China.Kaiwen Li Tianxin Lin Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang 2015Asian Journal of Urology2015,2,2:21
10Genome-scale profiling of circulating cell-free DNA signatures for early detection of hepatocellular carcinoma in cirrhotic patients显示文摘Dear Editor,Hepatocellular carcinoma(HCC)is the second most deadly cancer worldwide.1 Cirrhosis of different causes predisposes patients to HCC,increasing the annual HCC incidence by 2%–4%.1 The development of cirrhosis facilitates a series of genetic or epigenetic changes,resulting in the formation of dysplastic nodules,a premalignant stage in HCC.1 HCC diagnosis at an early stage contributes to an improved prognosis with the possibility of curative treatment.Due to the low accuracy of current diagnostic methods,it is urgently needed to explore new non-invasive strategies for early HCC diagnosis in cirrhotic patients.Lei Chen Ghassan K.Abou-Alfa Bo Zheng Jing-Feng Liu Jian Bai Lu-Tao Du Yun-Song Qian Rong Fan Xiao-Long Liu Lin Wu Jin-Lin Hou Hong-Yang Wang The PreCar Team 2021Cell Research2021,31,5:20
11Plasma miR-216a as a potential marker of pancreatic injury in a rat model of acute pancreatitis显示文摘AIM:To study the potential value and specificity of plasma miR-216a as a marker for pancreatic injury.METHODS:Two rat models were applied in this article:L-arginine-induced acute pancreatitis was used as one model to explore the potential value of plasma miR-216a for detection of pancreatic injury;nonlethal sepsis induced in rats by single puncture cecal ligation and puncture(CLP)was used as the other model to evaluate the specificity of plasma miR-216a compared with twocommonly used markers(amylase and lipase)for acute pancreatitis.Plasmas were sampled from rats at indicated time points and total RNA was isolated.Real-Time Quantitative reverse transcriptase-polymerase chain reaction was used to quantify miR-216a in plasmas.RESULTS:In the acute pancreatitis model,among five time points at which plasmas were sampled,miR-216a concentrations were significantly elevated 24 h after arginine administration and remained significantly increased until 48 h after operation(compared with 0 h time point,P<0.01,Kruskal-Wallis Test).In the CLP model,plasma amylase and lipase,two commonly used biomarkers for acute pancreatitis,were significantly elevated 24 h after operation(compared with 0 h time point,P<0.01 and 0.05 respectively,Pairwise Bonferroni corrected ttests),while miR-216a remained undetectable among four tested time points.CONCLUSION:Our article showed for the first time that plasma miR-216a might serve as a candidate marker of pancreatic injury with novel specificity.Xiang-Yu Kong,Yi-Qi Du,Lei Li,Xiao-Hua Man,Yan-Fang Gong,Li-Ning Xiao,Yong-Zhi Zheng,Shang-Xin Deng,Jun-Jun Gu,Zhao-Shen Li,Department of Gastroenterology,Changhai Hospital,Second Military Medical University,Shang-hai 200433,China Jian-Qiang Liu,Department of Gastroenterology,Fuzhou General Hospital of Nanjing Military Command,Fuzhou 350025,Fujian Province,China Guo-Kun Wang,Jia-Qi Zhu,Department of Cardiology,Changhai Hospital,Second Military Medical University,Shang-hai 200433,China 2010World Journal of Gastroenterology2010,16,36:19
12p53 upregulated by HIF-la promotes hypoxiainduced G2/M arrest and renal fibrosis in vitro and in vivo显示文摘Hypoxia plays an important role in the genesis and progression of renal fibrosis.The underlying mechanisms, however, have not been sufficiently elucidated. We examined the role of p53 in hypoxia-induced renal fibrosis in cell culture (human and rat renal tubular epithelial cells) and a mouse unilateral ureteral obstruction (UUO) model. Cell cycle of tubular cells was determined by flow cytometry, and the expression of profibrogenic factors was determined by RT-PCR, immunohistochemistry, and western blotting. Chromatin immunoprecipitation and luciferase reporter experiments were performed to explore the effect of HIF-lα on p53 expression. We showed that, in hypoxic tubular cells, p53 upregulation suppressed the expression of CDK1 and cyclins Bl and DI, leading to cell cycle (G2/M) arrest (or delay) and higher expression of TGF-β, CTGF, collagens, and fibronectin. p53 suppression by siRNA or by a specific p53 inhibitor (PIF-α) triggered opposite effects preventing the G2/M arrest and profibrotic changes. In vivo experiments in the UUO model revealed similar antifibrotic results following intraperitoneal administration of PIF-α(2.2 mg/kg). Using gain-of-function, loss-of-function, and luciferase assays, we further identified an HRE3 region on the p53 promoter as the HIF-lα-binding site. The HIF-la-HRE3 binding resulted in a sharp transcriptional activation of p53. Collectively, we show the presence of a hypoxia-activated, p53-responsive profibrogenic pathway in the kidney. During hypoxia, p53 upregulation induced by HIF-la suppresses cell cycle progression, leading to the accumulation of G2/M cells, and activates profibrotic TGF-β and CTGF-mediated signaling pathways, causing extracellular matrix production and renal fibrosis.Limin Liu Peng Zhang Ming Bai Lijie He Lei Zhang Ting Liu Zhen Yang Menglu Duan Minna Liu Baojian Liu Rui Du Qi Qian Shiren Sun 2019Journal of Molecular Cell Biology2019,11,5:18

15Submucosal tunneling endoscopic resection: An effective and safe therapy for upper gastrointestinal submucosal tumors originating from the muscularis propria layer显示文摘AIM To evaluate the effectiveness and safety of submucosal tunneling endoscopic resection(STER) and compare its outcomes in esophageal and cardial submucosal tumors(SMTs) of the muscularis propria(MP) layer.METHODS From May 2012 to November 2017, 173 consecutive patients with upper gastrointestinal(GI) SMTs of the MP layer underwent STER. Overall, 165 patients were included, and 8 were excluded. The baseline characteristics of the patients and SMTs were recorded. The en bloc resection rate, complete resection rate,residual rate, and recurrence rate were calculated to evaluate the effectiveness of STER, and the complication rate was recorded to evaluate its safety. Effectiveness and safety outcomes were compared between esophageal and cardial SMTs.RESULTS One hundred and twelve men and 53 women with a mean age of 46.9 ± 10.8 years were included. The mean tumor size was 22.6 ± 13.6 mm. Eleven SMTs were located in the upper esophagus(6.7%), 49 in the middle esophagus(29.7%), 46 in the lower esophagus(27.9%), and 59 in the cardia(35.7%). Irregular lesions accounted for 48.5% of all lesions. STER achieved an en bloc resection rate of78.7%(128/165) for GI SMTs with an overall complication rate of 21.2%(35/165).All complications resolved without intervention or were treated conservatively without the need for surgery. The en bloc resection rates of esophageal and cardial SMTs were 81.1%(86/106) and 72.1%(42/59), respectively(P = 0.142), and the complication rates were 19.8%(21/106) and 23.7%(14/59), respectively,(P =0.555). The most common complications for esophageal SMTs were gas-related complications and fever, while mucosal injury was the most common for cardial SMTs.CONCLUSION STER is an effective and safe therapy for GI SMTs of the MP layer. Its effectiveness and safety are comparable between SMTs of the esophagus and cardia.Chen Du Ning-Li Chai En-Qiang Ling-Hu Zhen-Juan Li Long-Song Li Jia-Le Zou Lei Jiang Zhong-Sheng Lu Jiang-Yun Meng Ping Tang 2019World Journal of Gastroenterology2019,25,2:17
16A Transcriptional Network Promotes Anthocyanin Biosynthesis in Tomato Flesh显示文摘Dietary anthocyanins are important health-promoting antioxidants that make a major contribution to the quality of fruits. It is intriguing that most tomato cultivars do not produce anthocyanins in fruit. However, the purple tomato variety Indigo Rose, which has the dominant Aft locus combined with the recessive atv locus from wild tomato species, exhibits light-dependent anthocyanin accumulation in the fruit skin. Here, we report that Aft encodes a functional anthocyanin activator named SlAN2-like, while atv encodes a nonfunctional version of the anthocyanin repressor SlMYBATV. The expression of SlAN2-like is responsive to light, and the functional SlAN2-like can activate the expression of both anthocyanin biosynthetic genes and their regulatory genes, suggesting that SlAN2-like acts as a master regulator in the activation of anthocyanin biosynthesis. We further showed that cultivated tomatoes contain nonfunctional alleles of SlAN2-like and therefore fail to produce anthocyanins. Consistently, expression of a functional SlAN2-like gene driven by the fruit-specific promoter in a tomato cultivar led to the activation of the entire anthocyanin biosynthesis pathway and high-level accumulation of anthocyanins in both the peel and flesh. Taken together, our study exemplifies that efficient engineering of complex metabolic pathways could be achieved through tissue-specific expression of master transcriptional regulators.Chuanlong Sun Lei Deng Minmin Du Jiuhai Zhao Qian Chen Tingting Huang Hongling Jiang Chang-Bao Li Chuanyou Li 2020Molecular Plant2020,13,1:17

18Phase 1 clinical trial demonstrated that MUC1 positive metastatic seminal vesicle cancer can be effectively eradicated by modified Anti-MUC1 chimeric antigen receptor transduced T cells显示文摘Recent progress in chimeric antigen receptor-modified T-cell(CAR-T cell) technology in cancer therapy is extremely promising, especially in the treatment of patients with B-cell acute lymphoblastic leukemia. In contrast, due to the hostile immunosuppressive microenvironment of a solid tumor, CAR T-cell accessibility and survival continue to pose a considerable challenge, which leads to their limited therapeutic efficacy. In this study, we constructed two anti-MUC1 CAR-T cell lines. One set of CAR-T cells contained SM3 single chain variable fragment(sc Fv) sequence specifically targeting the MUC1 antigen and co-expressing interleukin(IL) 12(named SM3-CAR). The other CAR-T cell line carried the SM3 sc Fv sequence modified to improve its binding to MUC1 antigen(named p SM3-CAR) but did not co-express IL-12. When those two types of CAR-T cells were injected intratumorally into two independent metastatic lesions of the same MUC1+ seminal vesicle cancer patient as part of an interventional treatment strategy, the initial results indicated no side-effects of the MUC1 targeting CAR-T cell approach, and patient serum cytokines responses were positive.
