| 1 | All-trans retinoic acid(ATRA)inhibits insufficient radiofrequency ablation(IRFA)-induced enrichment of tumor-initiating cells in hepatocellular carcinoma显示文摘Objective:Local recurrence of hepatocellular carcinoma(HCC)after radiofrequency ablation(RFA)treatment remains a serious problem.Tumor-initiating cells(TICs)are thought to be responsible for tumor relapse.Here,we investigated the effect of the TIC differentiation inducer,all-trans retinoic acid(ATRA),on RFA and explored the potential molecular mechanisms.Methods:The proportions of CD133+and epithelial cell adhesion molecule(Ep CAM);TICs in recurrent HCC after RFA and primary HCC were first determined in clinic.Then,the effect of heat intervention or insufficient RFA(IRFA)on the malignant potential of HCC cells,including cell migration,sphere formation ability,tumor growth,the proportion of CD133+and Ep CAM+TICs and expression of stem cell-related genes,was evaluated in vitro and in vivo.Finally,the effect of ATRA on the tumor growth and the proportion of TICs was evaluated.Results:In clinical data,a higher proportion of CD133+and Ep CAM+TICs was found in recurrent tumors than in primary tumors.In vitro heat intervention promoted the cell migration and sphere formation ability.Additionally,it increased the proportion of CD133+and Ep CAM+TICs and the expression of stem cell-related genes.In addition,after IRFA the residual tumors in xenografts grew faster and had more TICs than untreated tumors.ATRA remarkably inhibited residual tumor growth after IRFA by elimination of TICs though the PI3 K/AKT pathway.Combination treatment with ATRA resulted in longer survival outcomes in mouse xenografts than RFA alone.Conclusions:ATRA,as a TIC differentiation inducer,could help to improve the effect of RFA treatment,which was partially attributed to its effect against TICs.The data indicated its potential as an alternative drug in the development of better therapeutic strategies for use in combination with RFA. | Song Wang Jingtao Liu Hao Wu Anna Jiang Kun Zhao Kun Yan Wei Wu Haibo Han Yanhua Zhang Wei Yang | 2021 | Chinese Journal of Cancer Research2021，33，6： | 2 |
| 2 | 间质蛋白Periostin高表达对鼻咽癌6-10B细胞凋亡的影响及可能机制显示文摘目的探讨间质蛋白Periostin高表达对鼻咽癌6-10B细胞凋亡的影响及其可能机制。方法流式细胞术及Western blot技术检测Periostin高表达前后6-10B细胞凋亡率的变化及凋亡相关蛋白Bax、Bcl-2、P53和p-Akt的表达;用稳定转染POSTN的6-10B细胞(6-10B POSTN细胞)及对照组6-10B系列细胞的培养上清,分别刺激6-10B细胞,检测刺激前后6-10B细胞中凋亡相关蛋白Bax、Bcl-2、P53和p-Akt的表达。将人P53 shRNA干扰载体转染到6-10B、6-10B-GFP和6-10B-POSTN细胞中,流式细胞术检测干扰P53后细胞的凋亡率。结果与对照组比较,Periostin高表达后6-10B细胞凋亡率明显升高,Bax和P53蛋白表达上调,Bcl-2的表达差异无显著性,但Bax/Bcl-2比值显著升高,p-Akt蛋白表达显著下调。Periostin高表达的6-10B细胞培养上清培养6-10B后,凋亡率较对照组显著升高。下调6-10B细胞中P53基因后,6-10B细胞的凋亡率较对照组无明显改变,而Periostin高表达的6-10B细胞的凋亡率较对照组显著升高。结论Periostin蛋白的表达上调可以促进鼻咽癌细胞的凋亡;其促凋亡机制与鼻咽癌组织中P53蛋白表达上调无关。 | 肖萍 李通 杨晓玉 李美香 | 2021 | 中南医学科学杂志2021，49，6： | 0 |
