| 1 | In vitro effect of iASPP on cell growth of oral tongue squamous cell carcinoma显示文摘iASPP is an inhibitory member of the apoptosis-stimulating proteins of P53(ASPP) family. iASPP is over expressed in several malignant tumors and potentially affects cancer progression. However, the expression and potential role of iASPP in oral tongue squamous cell carcinoma(OTSCC) have not been addressed. In our study, we detected iASPP expression in OTSCC by immunohistochemistry. iASPP expression is up-regulated in OTSCC tissues. Moreover, in clinical pathology specimens, we found that increased iASPP expression correlates with poor differentiation and lymph node metastasis. Using multicellular tumor spheroids(MTS) and flow cytometry, we demonstrated that iASPP down-regulation arrests OTSCC cells at the G0/G1 phase, induces OTSCC cell apoptosis and inhibits OTSCC cell proliferation. These results indicate that iASPP plays a significant role in the progression of OTSCC and may serve as a biomarker or therapeutic target for OTSCC patients. | Yu Chen Wangxiang Yan Shuqi He Jiechun Chen Dan Chen Zhaoqiang Zhang Zhiguo Liu Xueqiang Ding Anxun Wang | 2014 | Chinese Journal of Cancer Research2014，26，4： | 7 |
| 2 | Aberrant translation regulated by METTL1/WDR4-mediated tRNA N7-methylguanosine modification drives head and neck squamous cell carcinoma progression显示文摘Background:Cancer cells selectively promote the translation of oncogenic tran-scripts to stimulate cancer progression.Although growing evidence has revealed that tRNA modifications and related genes participate in this process,their roles in head and neck squamous cell carcinoma(HNSCC)remain largely unchar-acterized.Here,we sought to investigate the function and mechanisms of the transfer RNA(tRNA)N7-methylguanosine(m'G)modification in regulating the occurrence and development of HNSCC.Methods:Cell lost of-function and gain-of function assays,xenograft models,conditional knockout and knockin mouse models were used to study the physi-ological functions of tRNA m'G modification in HNSCC tumorigenesis.tRNA modification and expression profiling,mRNA translation profiling and res-cue assays were performed to uncover the underlying molecular mechanisms.Single-cell RNA sequencing(scRNA seq)was conducted to explore the tumor microenvironment changes.Results:The tRNA.m7G methyltransferase complex components Methyltransferase-like 1(METTL1)/WD repeat domain 4(WDR4)were upregulated in HNSCC and associated with a poor prognosis.Functionally,METTL1/WDR4 promoted HNSCC progression and metastasis in cell-based and transgenic mouse models.Mechanistically,ablation of METTL1 reduced the m'G levels of 16 tRNAS,inhibiting the translation of a subset of oncogenic transcripts,including genes related to the phosphatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin(PI3K/AKT/mTOR)signaling pathway.In addition,chemical modulators of the PI3K/Akt/mTOR signaling pathway reversed the effects of Mettll in mouse HNSCC.Furthermore,scRNA-seq results revealed that Mettll knockout in mouse tumor cells altered the immune landscape and cell-cell interaction between the tumor and stromal compartment.Conclusions:The tRNA m?G methyltransferase METTLI was found to promote the development and malignancy of HNSCC through regulating global mRNA translation,including the PI3K/AKT/mTOR signaling pathway,and found to alter immune landscape.METTLI could be a promising treatment target for HNSCC patients. | Jie Chen Kang Li Jianwen Chen Xiaochen Wang Rongsong Ling Maosheng Cheng Zhi Chen Fangfang Chen Qianting He Shuai Li Caihua Zhang Yizhou Jiang Qianming Chen Anxun Wang Demeng Chen | 2022 | Cancer Communications2022，42，3： | 6 |

| 4 | Suppressed mitochondrial respiration via NOX5-mediated redox imbalance contributes to the antitumor activity of anlotinib in oral squamous cell carcinoma显示文摘Anlotinib,a novel multitarget tyrosine kinase inhibitor,has shown promising results in the management of various carcinomas.This study aimed to investigate the antitumor activity of anlotinib in oral squamous cell carcinoma(OSCC)and the underlying molecular mechanism.A retrospective clinical study revealed that anlotinib improved the median progression-free survival(m PFS)and median overall survival(m OS)of patients with recurrent and metastatic(R/M)OSCC,respectively.Functional studies revealed that anlotinib markedly inhibited in vitro proliferation of OSCC cells and impeded in vivo tumor growth of OSCC patientderived xenograft models.Mechanistically,RNA-sequencing identified that oxidative stress,oxidative phosphorylation and AKT/m TOR signaling were involved in anlotinib-treated OSCC cells.Anlotinib upregulated NADPH oxidase 5(NOX5)expression,elevated reactive oxygen species(ROS)production,impaired mitochondrial respiration,and promoted apoptosis.Moreover,anlotinb also inhibited phosphoAkt(p-AKT)expression and elevated p-e IF2αexpression in OSCC cells.NOX5 knockdown attenuated these inhibitory effects and cytotoxicity in anlotinib-treated OSCC cells.Collectively,we demonstrated that anlotinib monotherapy demonstrated favorable anticancer activity and manageable toxicities in patients with R/M OSCC.The antitumor activity of anlotinib in OSCC may be mainly involved in the suppression of mitochondrial respiration via NOX5-mediated redox imbalance and the AKT/e IF2αpathway. | Zhexun Huang Qiao Su Wuguo Li Hui Ren Huiqiang Huang Anxun Wang | 2021 | Journal of Genetics and Genomics2021，48，7： | 1 |

| 7 | Bioadaptation of implants to In vitro and In vivo oxidative stress pathological conditions via nanotopography-induced FoxO1 signaling pathways to enhance Osteoimmunal regeneration显示文摘Varieties of pathological conditions,including diabetes,are closely related to oxidative stress(OS),but the osseointegration or bioadaptation of implants to OS and the related mechanism remain poorly explored.In this study,the antioxidation and osteoimmune regeneration of titanium implants with micro/nanotopographies were evaluated under H2O2-,lipopolysaccharide(LPS)-and hyperglycemia-mediated cellular OS models and in diabetic rats as a representative animal model of OS.TiO2 nanotube(TNT)coating on titanium implants directly induced superior osteogenic differentiation of bone mesenchymal stem cells(MSCs)and osseointegration compared with microscale sand blasted-acid etched topography(SLA)under OS,attributed to higher superoxide dismutase 2 activity,the neutralization of intracellular reactive oxygen species(ROS),and less apoptosis.Mechanistically,the oxidation resistance on TNT is driven by upregulated forkhead box transcription factor O1(FoxO1),which is abolished after knockdown of FoxO1 via shRNA in MSCs.Indirectly,TNT also alleviates OS in macrophages,therefore inducing a higher portion of the M2 phenotype under OS with increased secretion of the anti-inflammatory cytokine IL-10,further promoting the osseoimmunity capacity compared with SLA.The current study not only suggests the potential application of TiO2 nanotube-coated titanium implants in compromised conditions but also provides a systematic evaluation strategy for the future development of bone biomaterials. | Jingyan Huang Ruoqi Li Jinghong Yang Min Cai Yichen Lee Anxun Wang Bin Cheng Yan Wang | 2021 | Bioactive Materials2021，6，10： | 1 |

| 12 | A comprehensive profile of TCF1^(+)progenitor and TCF1−terminally exhausted PD-1^(+)CD8^(+)T cells in head and neck squamous cell carcinoma:implications for prognosis and immunotherapy显示文摘The heterogeneity of exhausted T cells(Tex)is a critical determinant of immune checkpoint blockade therapy efficacy.However,few studies have explored exhausted T cell subpopulations in human cancers.In the present study,we examined samples from two cohorts of 175 patients with head and neck squamous cell cancer(HNSCC)by multiplex immunohistochemistry(mIHC)to investigate two subsets of Tex,CD8+PD1+TCF1+progenitor exhausted T cells(TCF1+Texprog)and CD8+PD1+TCF1−terminally exhausted T cells(TCF1−Texterm).Moreover,fresh tumor samples from 34 patients with HNSCC were examined by flow cytometry and immunohistochemistry to further investigate their properties and cytotoxic capabilities and their correlation with regulatory T cells(Tregs)in the tumor immune microenvironment(TIME).mIHC and flow cytometry analysis showed that TCF1−Texterm represented a greater proportion of CD8+PD1+Tex than TCF1+Texprog in most patients.TCF1+Texprog produced abundant TNFα,while TCF1−Texterm expressed higher levels of CD103,TIM-3,CTLA-4,and TIGIT.TCF1−Texterm exhibited a polyfunctional TNFα+GZMB+IFNγ+phenotype;and were associated with better overall survival and recurrence-free survival.The results also indicated that larger proportions of TCF1−Texterm were accompanied by an increase in the proportion of Tregs.Therefore,it was concluded that TCF1−Texterm was the major CD8+PD1+Tex subset in the HNSCC TIME and that these cells favor patient survival.A high proportion of TCF1−Texterm was associated with greater Treg abundance. | Dikan Wang Juan Fang Shuqiong Wen Qunxing Li Jinming Wang Lisa Yang Wenxiao Dai Huanzi Lu Junyi Guo Zhongyan Shan Wenqiang Xie Xiangqi Liu Liling Wen Jie Shen Anxun Wang Qianming Chen Zhi Wang | 2022 | International Journal of Oral Science2022，14，1： | 0 |
