| 1 | Melatonin enhances radiofrequency-induced NK antitumor immunity,causing cancer metabolism reprogramming and inhibition of multiple pulmonary tumor development显示文摘Surgery is the comm on treatme nt for early lung cancer with multiple pulm onary no dules,but it is often accompanied by the problem of significant malignancy of other nodules in non-therapeutic areas.In this study,we found that a combined treatment of local rad iofreq ue ncy ablati on(RFA)and melatonin(MLT)greatly improved clinical outcomes for early lung cancer patie nts with multiple pulmonary nodules by minimizing lung function injury and reducing the probability of malignant transformation or enlargement of nodules in non-ablated areas.Mechanically,as demonstrated in an associated mouse lung tumor model,RFA not only effectively remove treated tumors but also stimulate antitumor immunity,which could inhibit tumor growth in non-ablated areas.MLT enhanced RFA-stimulated NK activity and exerted synergistic antitumor effects with RFA.Transcriptomics and proteomics analyses of residual tumor tissues revealed enhanced oxidative phosphorylation and reduced acidification as well as hypoxia in the tumor microenvironment,which suggests reprogrammed tumor metabolism after combined treatment with RFA and MLT.Analysis of residual tumor further revealed the depressed activity of MAPK,NF-kappa B,Wnt,and Hedgehog pathways and upregulated P53 pathway in tumors,which was in line with the inhibited tumor growth.Combined RFA and MLT treatment also reversed the Warburg effect and decreased tumor malignancy.These findings thus demonstrated that combined treatment of RFA and MLT effectively inhibited the malignancy of non-ablated nodules and provided an innovative non-invasive strategy for treating early lung tumors with multiple pulmonary nodules.Trial registration:www.chictr.org.cn,identifier ChiCTR2100042695,http://gffzz62a03ee25e6f4a77hk5q9n66bcn666q0f.ffgz.tsg.suse.edu.cn/showproj.aspx?proj=120931. | Ming Li Bingjie Hao Menghuan Zhang Russel J.Reiter Shumeng Lin Tiansheng Zheng Xiangyun Chen Yanbei Ren Liduo Yue Baigenzhin Abay Guojie Chen Xiao Xu Yufeng Shi Lihong Fan | 2021 | Signal Transduction and Targeted Therapy2021，6，10： | 6 |

| 3 | CPT1C-mediated fatty acid oxidation facilitates colorectal cancer cell proliferation and metastasis显示文摘Fatty acid oxidation(FAO)has been proven to be an accomplice in tumor progression.Carnitine palmitoyltransferase 1C(CPT1C),a rate-limiting enzyme in FAO,mainly functions to catalyze fatty acid carnitinylation and guarantee subsequent entry into the mitochondria for FAO in colorectal cancer(CRC).Gene expression data and clinical information extracted from The Cancer Genome Atlas(TCGA)database show significantly higher expression of CPT1C in patients with metastatic CRC(P=0.005).Moreover,overexpression of CPT1C is correlated with worse relapse-free survival in CRC(HR 2.1,P=0.0006),while no statistical significance is indicated for CPT1A and CPT1B.Further experiments demonstrate that downregulation of CPT1C expression leads to a decrease in the FAO rate,suppression of cell proliferation,cell cycle arrest and repression of cell migration in CRC,whereas opposite results are obtained when CPT1C is overexpressed.Furthermore,an FAO inhibitor almost completely reverses the enhanced cell proliferation and migration induced by CPT1C overexpression.In addition,analysis of TCGA data illustrates a positive association between CPT1C expression and HIF1αlevel,suggesting that CPT1C is a transcriptional target of HIF1α.In conclusion,CPT1C overexpression indicates poor relapse-free survival of patients with CRC,and CPT1C is transcriptionally activated by HIF1α,thereby promoting the proliferation and migration of CRC cells. | Jing Li Wanwei Zheng Jie Wu Jun Zhang Bin Lv Wenshuai Li Jie Liu Xin Zhang Tiansheng Huang Zhongguang Luo | 2023 | Acta Biochimica et Biophysica Sinica2023，55，8： | 1 |

| 5 | Regulation of hypoxic stress and oxidative stress in bone grafting: Current trends and future perspectives显示文摘Tissue engineering aims to offer large-scale replacement of damaged organs using implants with the com-bination of cells,growth factors and scaffolds.However,the intra/peri-implant region is exposed to se-vere hypoxic stress and oxidative stress during the early stage of implantation with bone graft materials,which endangers the survival,proliferation and differentiation of seed cells within the implants as well as the host cells surrounding the implants.If the bone graft material could spontaneously and intelligently regulate the hypoxic stress and oxidative stress to a moderate level,it will facilitate the vascularization of the implants and the rapid regeneration of the bone tissue.In this review,we will first introduce the signaling pathways of cellular response under hypoxic stress and oxidative stress,then present the clas-sical material designs and examples in response to hypoxic stress and oxidative stress.And finally,we will address the important role of epigenetic mechanisms in the regulation of hypoxic stress and oxida-tive stress and describe the potential applications and prospective smart bone graft materials based on novel epigenetic factors against hypoxic stress and oxidative stress in bone repair.The main content of this review is summarized in the following graphical abstract. | Hao Hu Xiao Liu Jun Chen Shangbin Cui Hualin Yi Gang Wang Renxian Wang Tiansheng Zheng Ben Wan Zhiyu Zhou Yong Wan Manman Gao Dafu Chen Xuenong Zou | 2023 | Journal of Materials Science & Technology2023，，26： | 0 |
| 6 | Biomimetic hydroxyapatite coating on the 3D-printed bioactive porous composite ceramic scaffolds promoted osteogenic differentiation via PI3K/AKT/mTOR signaling pathways and facilitated bone regeneration in vivo显示文摘The architecture and surface modifications have been regarded as effective methods to enhance the bi-ological response of biomaterials in bone tissue engineering.The porous architecture of the implanta-tion was essential conditions for bone regeneration.Meanwhile,the design of biomimetic hydroxyap-atite(HAp)coating on porous scaffolds was demonstrated to strengthen the bioactivity and stimulate osteogenesis.However,bioactive bio-ceramics such asβ-tricalcium phosphate(β-TCP)and calcium sili-cate(CS)with superior apatite-forming ability were reported to present better osteogenic activity than that of HAp.Hence in this study,3D-printed interconnected porous bioactive ceramicsβ-TCP/CS scaf-fold was fabricated and the biomimetic HAp apatite coating were constructed in situ via hydrothermal reaction,and the effects of HAp apatite layer on the fate of mouse bone mesenchymal stem cells(mBM-SCs)and the potential mechanisms were explored.The results indicated that HAp apatite coating en-hanced cell proliferation,alkaline phosphatase(ALP)activity,and osteogenic gene expression.Further-more,PI3K/AKT/mTOR signaling pathway is proved to have an important impact on cellular functions.The present results demonstrated that the key molecules of phosphatidylinositol 3-kinase(PI3K),protein kinase B(AKT)and mammalian target of rapamycin(mTOR)were activated after the biomimetic hydrox-yapatite coating were constructed on the 3D-printed ceramic scaffolds.Besides,the activated influence on the protein expression of Runx2 and BMP2 could be suppressed after the treatment of inhibitor HY-10358.In vivo studies showed that the constructed HAp coating promoted bone formation and strengthen the bone quality.These results suggest that biomimetic HAp coating constructed on the 3D-printed bioac-tive composite scaffolds could strengthen the bioactivity and the obtained biomimetic multi-structured scaffolds might be a potential alternative bone graft for bone regeneration. | Bizhi Tan Naru Zhao Wei Guo Fangli Huang Hao Hu Yan Chen Jungang Li Zemin Ling Zhiyuan Zou Rongcheng Hu Chun Liu Tiansheng Zheng Gang Wang Xiao Liu Yingjun Wang Xuenong Zou | 2023 | Journal of Materials Science & Technology2023，，5： | 0 |
| 7 | Atomically precise gold nanoclusters for healthcare applications显示文摘The potential application of gold nanoparticles(GNPs)in biomedicine has been extensively reported.However,there is still too much puzzle about their real face and potential health risks in comparison with the commercial drug molecules.The emergence of atomically precise gold nanoclusters(APGNCs)provides the opportunity to address the puzzle due to their ultrasmall size,defined molecular formula,editable surface engineering,available structures and unique physicochemical properties including excellent biocompatibility,strong luminescence,enzyme-like activity and efficient renal clearance,et al.Recently,these advantages of APGNCs also endow them promising performances in healthcare such as bioimaging,drug delivery,antibacterial and cancer therapy.Especially,their clear composition and structures like the commercial drug molecules facilitate the study of their functions and the structure-activity relationship in healthcare,which is essential for the guided design of APGNC nanomedicine.Therefore,this review will focus the advantages and recent progress of APGNCs in health care and envision their prospects for the future. | Tiansheng Wei Congcong Mi Yan Sun Yining Chen Xiaoyang Hu Zibao Gan Xiuwen Zheng | 2023 | Biomedical Engineering Communications2023，2，4： | 0 |
| 8 | Promotion of liquid-to-solid phase transition of cGAS by Baicalein suppresses lung tumorigenesis显示文摘Dear Editor,Kras and p53 mutation are among the most common gene mutations in lung cancer,which has both the highest incidence and mortality rate among cancers.1 Kras/p53 mutation also causes mitochondrial dysfunction,which has been implicated to promote the inflammation-to-cancer transition.2 We established a lung adenocarcinoma model by using conditional alleles of KrasLSLG12D/p53flox/flox in mice3 to evaluate the effect of Baicalein(5,6,7-trihydroxyflavone),a principal component of Scutellaria baicalensis in traditional Chinese medicine,4 on the initiation and progression of lung cancer.Cre-mediated expression of KrasG12D and deletion of p53 caused obvious tumor lesions in the lung,which were strongly inhibited by the administration of Baicalein(Fig.1a,b and Supplementary Fig.1a,b),indicating that Baicalein is highly potent in inhibiting the progression of primary lung cancer. | Tiansheng Zheng Haipeng Liu Yifan Hong Yajuan Cao Qing Xia Chengge Qin Ming Li Russel J.Reiter Yidong Bai Lihong Fan | 2023 | Signal Transduction and Targeted Therapy2023，8，4： | 0 |
