Effect of GSDME on chemoresistance in ovarian cancer

:1363-1371
 
目的 探讨卵巢癌化学治疗(化疗)耐药与焦孔素E(GSDME)基因的甲基化是否有关, 以及地西他滨是否可以通过去甲基化使GSDME蛋白表达水平升高从而逆转卵巢癌化疗耐药。方法 顺铂逆浓度梯度构建SKOV-3卵巢癌耐顺铂细胞株(SKOV-3/DDP); CCK8法检测耐药前后细胞株的半抑制浓度(IC50); 实时荧光定量甲基化特异性PCR法检测两组细胞中GSDME基因的甲基化水平; Wetern Blot检测两组细胞中GSDME的表达水平。将耐药细胞株用不同质量浓度的地西他滨处理,重复上述实验, 检测地西他滨处理前后细胞的IC50GSDME基因的甲基化水平及GSDME蛋白的表达程度。结果 与SKOV-3细胞相比, SKOV-3/DDP中GSDME基因的甲基化水平升高(P<0.01), 同时GSDME蛋白的表达水平降低(P<0.001); 随着地西他滨作用浓度的升高, 耐药细胞中GSDME基因的甲基化程度逐渐降低, 蛋白的表达水平逐渐升高, 细胞的IC50逐渐降低:在用0.5 μg/mL地西他滨处理耐药细胞后GSDME基因的甲基化水平虽然降低(P<0.01), 但是此时蛋白的表达水平及耐药细胞的IC50均无明显改变(P>0.05); 当地西他滨的浓度增加到1.0 μg/mL时蛋白的表达水平才明显升高(P<0.05), 而此时细胞的IC50仍未见明显降低(P>0.05); 待药物浓度达到1.5 μg/mL时, 细胞的IC50才表现出明显的下降趋势(P<0.05)。结论 GSDME的表达与卵巢癌的化疗耐药密切相关, GSDME的高甲基化水平致使其低表达可促进卵巢癌的化疗耐药。但地西他滨可以通过去甲基化使卵巢癌耐药细胞中GSDME的表达水平升高, 从而增加卵巢癌细胞对化疗药物的敏感性, 进而逆转卵巢癌化疗耐药。
Objective To explore whether drug resistance in ovarian cancer is associated with gasdermin E(GSDME) methylation, and to explore whether decitabine can reverse ovarian cancer chemoresistance by increasing GSDME protein expression levels through demethylation.Methods The cisplatin-resistant cell line(SKOV-3/DDP)was constructed by inverse concentration gradient of cisplatin.Semi-inhibitory concentration(IC50)of cell lines after drug resistance was detected using the CCK8 assay.Real-time fluorescence quantitative methylation-specific PCR was used to detect the methylation level of GSDME gene in the two groups of cells.Wetern Blot was used to detect the expression level of GSDME in the two groups of cells.Drug-resistant cell lines were treated with different concentrations of the demethylating drug decitabine.Experiments above were repeated to detect the methylation degree of IC50 and GSDME genes and the expression level of GSDME protein in drug-resistant cells before and after decitabine treatment.Results Compared with SKOV-3 cells, the methylation level of GSDME gene in SKOV-3/DDP was significantly increased(P<0.01), while the expression level of GSDME protein was significantly decreased(P<0.001).With the increase of decitabine concentration, the methylation degree of GSDME gene in drug-resistant cells was gradually decreased, the expression level of protein was gradually increased, and the IC50 of cells was gradually decreased:the methylation level of GSDME gene was decreased after 0.05 μg/mL decitabine treatment(P<0.01), but there were no significant changes in protein expression level and IC50 of drug-resistant cells(P>0.05).The protein expression level was significantly increased when the concentration of local citabine was increased to 0.10 μg/mL(P<0.05), while the IC50 of the cells was not significantly decreased(P>0.05).When the drug concentration reached 0.15 μg/mL, he IC50 of the cells showed a significant downward trend(P<0.05).Conclusions The expression of GSDME is closely related to chemoresistance in ovarian cancer, and the low expression of GSDME due to its high methylation level can promote chemoresistance in ovarian cancer.However, decitabine can increase the expression level of GSDME in drug-resistant ovarian cancer cells through demethylation,thereby increasing the sensitivity of ovarian cancer cells to chemotherapeutic drugs, and then reversing the chemoresistance of ovarian cancer.

背景 虚拟标准化患者作为医学教育中的新型教学工具, 已广泛用于提升学生的临床问诊能力。随着生成式人工智能的快速发展, 基于大语言模型(LLMs)构建的VSP系统成为研究热点。然而, 目前尚缺乏对不同LLM在模拟患者角色方面表现的系统比较。目的 比较ChatGPT-4o与DeepSeek两种主流LLM在VSP模拟中的适用性, 评估其在病史采集、语言自然度、线索引导能力及教学辅助效果等方面的表现差异。方法 采用类实验研究,参与者为某医学院校临床医学专业本科四年级学生, 所有参与者均已修完《诊断学》课程, 具备基础问诊技能, 研究对象共60人, 按学号尾数单双分为两组, 分别与ChatGPT-4o或DeepSeek驱动的VSP系统进行交互。进行模拟急性阑尾炎问诊, 并在完成病史采集后提交诊断判断与体验问卷。结果 ChatGPT-4o在结构化信息整合、线索引导及技术稳定性方面更为优越, 而DeepSeek则在语言亲和力与情感回应方面表现更具人文关怀色彩。结论 不同LLM在VSP中的优势方向不同, 可根据教学目标进行有针对性地系统选择与设计。未来研究可进一步拓展至不同病种、交互方式及评估维度,以全面评估LLM驱动VSP在医学教育场景下的适应性与教学成效。
Background Virtual standardized patients(VSPs)have emerged as a novel tool in medical education, widely adopted to enhance students’ clinical interview skills.With the rapid development of generative artificial intelligence, VSP systems powered by large language models(LLMs)have become a new focus of research.However, few studies have systematically compared the performance of different LLMs in simulating patient roles.Objective This study aims to compare the applicability of two mainstream LLMs, ChatGPT-4o and DeepSeek, in VSP-based medical interview simulations, focusing on their differences in history-taking performance,linguistic naturalness, clue guidance,and educational support.Methods A quasi-experimental study was conducted involving 60 fourth-year clinical medicine undergraduates from a medical school.All participants had completed a diagnostics course and possessed basic interviewing skills.Students were assigned to either the ChatGPT-4o or DeepSeek group based on the parity of their student ID numbers.Each participant conducted a text-based simulated interview with a VSP presenting with acute appendicitis, then submitted both a preliminary diagnosis and a structured satisfaction questionnaire.Results ChatGPT-4o demonstrated superior performance in structured information integration, clue-based prompting, and system stability.In contrast, DeepSeek showed more natural language affinity and emotional responsiveness,reflecting stronger humanistic communication traits.The two models displayed divergent strengths within the VSP framework, suggesting that system selection and integration should be tailored to specific teaching objectives.Conclusions Future research should expand the scope to include diverse disease scenarios, interaction modalities, and evaluation dimensions, to comprehensively assess the educational utility and adaptability of LLM-driven VSP systems in medical training.
