Objective To explore the diagnostic value of clinical features combined with peripheral blood vascular endothelial growth factor(VEGF)and α-hydroxybutyrate dehydrogenase(α-HBDH)levels in ovarian cancer.Methods A total of 84 patients with malignant ovarian cancer admitted to the gynecology department of Tianjin Central Hospital of Gynecology and Obstetrics from June 2022 to June 2024 were included in the observation group,and 84 patients with benign ovarian lesions during the same period were included in the control group.The clinical data and VEGF,α-HBDH levels of the two groups were compared.Pearson analysis was used to explore the correlation between VEGF,α-HBDH levels,and clinical characteristics of patients with malignant ovarian cancer.Binary Logistic regression analysis was conducted to identify independent risk factors for malignant ovarian cancer,and receiver operating characteristic(ROC) curves were used to analyze the diagnostic value of VEGF and α-HBDH levels for malignant ovarian cancer.Results The observation group had significantly higher age,BMI,and serum CA125,HE4,VEGF,α-HBDH levels compared to the control group(P<0.05).VEGF and α-HBDH levels were significantly positively correlated with FIGO stage,differentiation grade,and lymph node metastasis(P<0.05).Age,BMI,VEGF,and α-HBDH were included as independent variables in binary Logistic regression,and the results showed that BMI,VEGF,and α-HBDH levelswere independent risk factors for malignant ovarian cancer(P<0.05).ROC curve analysis revealed that the AUC for combined detection of VEGF and α-HBDH reached 0.921,with sensitivity and specificity of 81.0% and 91.7%,respectively,significantly superior to individual detection(VEGF:AUC=0.702;α-HBDH:AUC=0.796).Conclusions The detection of BMI combined with VEGF and α-HBDH levels can provide an efficient and noninvasive auxiliary means for the diagnosis of ovarian cancer,which has important clinical application potential.
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IC50、GSDME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.

Objective To explore the relationship between m6A methylated genes and prognosis of ovarian cancer, so as to provide scientific basis for targeted therapy and prognosis assessment of ovarian cancer. Methods The mRNA expression data of ovarian cancer tissues and normal tissues were downloaded from TCGA and GTEx databases for difference analysis between two groups. The genes related to ovarian cancer survival were screened by LASSO regression, and the risk score prediction model was further constructed by step Cox regression analysis. The patients were divided into high-risk group and low-risk group according to the median risk score, and the ROC was used for analysis. Correlation analysis was performed to construct an expression regulatory network with m6A genes, and GO function enrichment and KEGG pathway analysis were performed to preliminarily explore the potential biological mechanism. Results 20 m6A methylation genes were found in differential expression between cancer tissue and normal tissue, three genes (HNRNPA2B1, ZC3H13, WTAP) were used to construct the model through step Cox regression analysis. Patients' survivals of high-risk group were shortened than that of the low-risk group obviously (P=0.001 9), the risk of death significantly was increased (HR=2.643, P<0.01). After risk score model combined with patient age, clinical classification and stage, the AUC of 1, 3, 5 years was 0.74, 0.64 and 0.64. Bioinformatics analysis indicated that those m6A genes were involved in RNA splicing, localization, transport, metabolic regulation, proteolysis, cell cycle, ribosome synthesis and other biological processes. Conclusion The prognostic risk assessment model of m6A methylated genes for ovarian cancer was successfully constructed and the model had certain predictive efficacy.

Objective To detect the expression of SNCG in ovarian cancer tissue and its clinical significance, to clarify the relationship between the expression of SNCG in human ovarian cancer and the degree of malignancy, so as to provide theoretical basis for the diagnosis, treatment and prognosis of clinical ovarian cancer. Methods From January 2010 to January 2015 in First Affiliated Hospital of Medical College of Shihezi University,119 patients with ovarian cancer and 50 patients with normal ovarian which had complete clinical data and paraffin section were selected. Immunohistochemical method was used to detect ovarian SNCG expression, and the expression of SNCG relationship with clinical pathological characteristics and prognosis of patients with ovarian cancer was analyzed. Results The expression of SNCG in ovarian cancer tissue was significantly higher than that in normal ovarian tissue (χ2=73.575,P<0.001). SNCG expression was correlated with tumor stage, degree of differentiation, lymph node metastasis, satisfying tumor reduction, CA125 and HE4 levels in ovarian cancer patients, and the differences were statistically significant (P<0.05). It was not correlated with the tumor primary site, ascites, recurrence of ovarian tumor and chemotherapy resistance, and the differences were not statistically significant (P>0.05).The overexpression of SNCG was correlated with PFS and OS in HGSOC patients, and the differences were statistically significant (P<0.05). Analysis of multivariate Cox proportional risk model showed that SNCG was an independent prognostic factor in patients with HGSOC, related to PFS (HR=2.107,95%CI: 1.014-3.795,P=0.034) and OS (HR=1.238,95%CI: 0.716-1.928,P=0.047). Conclusion The high expression of SNCG in ovarian cancer is related to tumor stage, degree of differentiation, lymph node metastasis, satisfying tumor reduction, CA125 and HE4 expressions, but it is not related to the recurrence of ovarian cancer or chemotherapy resistance. The overexpression of SNCG protein can be used as an independent prognostic factor in patients with HGSOC for clinical diagnosis and treatment guidance.
