In this study, we examined the impact of long intergenic non-protein coding RNA 01234 (LINC01234) in the diagnosis and survival of UCEC using an open high-throughput sequencing database. The association between LINC01234 expression and UCEC clinical features was determined using the Wilcoxon rank sum test, logistic regression and Cox regression. To assess the classification effectiveness of LINC01234 in UCEC, the area under the receiver operating characteristic (ROC) curve (AUC) was performed. Then, Kaplan-Meier analysis was performed to determine the prognostic significance of LINC01234 in UCEC. The underlying regulatory mechanisms of LIN01234 were assessed using the Gene set enrichment analysis (GSEA), and the influence on immune infiltration cells was tested by the Spearman correlation method. Datebases showed LINC01234 was up-regulated in UCEC and associated with poor clinicopathologic characteristics. What’s more quantitative real time polymerase chain reaction (qRT-PCR) analyse of clinical tissue specimens, LINC01234 was actually high expression in UCEC. The results showed an AUC of 0.726, indicating that LINC01234 had a significant diagnostic value. Further, Kaplan-Meier analysis showed that high LINC01234 expression was associated with poorer progress free interval (PFI) (hazard ratio (HR): 1.68, 95% confidence interval (CI): 1.18–2.39, p = 0.004), disease-specific survival (DSS) (HR: 2.17, 95% CI: 1.29–3.67, p = 0.004), overall survival (OS) (HR: 1.81, 95% CI: 1.19–2.75, p = 0.005). Cox regression analysis showed LINC01234 expression was an independent factor for DSS. Pathway enrichment and immune infiltration analysis showed the most likely mechanisms that LINC01234 promoted tumor progression. LINC01234 demonstrated diagnostic and prognostic potential in UCEC and was shown to exert its effects via various mechanisms, including cell proliferation, spermatogenesis, angiogenesis and immune response in the tumor microenvironment, to promote tumor progression; thus, indicating that it could be a target for treating UCEC.","PeriodicalId":11903,"journal":{"name":"European journal of gynaecological oncology","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136115082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Programmed cell death (PCD) plays an important role in the genesis and progression of tumors. Necroptosis is a novel form of PCD that does not rely on the caspase system. However, the role of necroptosis in EC is unclear. Transcriptome data of endometrial cancer were downloaded from The Cancer Genome Atlas (TCGA) database and log2 conversion was performed. Expression analysis and correlation analysis were performed to explore necroptosis gene expression and interaction in EC. Lasso regression was used to construct necroptosis-related prognostic signature. Finally, immunocorrelation analysis and single cell sequencing analysis were used to explore the significance of this signature in EC tumor microenvironment. A total of 15 of the 17 necroptosis genes were differentially expressed in EC. Subsequently, necroptosis related prognostic signature was constructed through Lasso regression. Riskscore = (−0.0999) × Toll-likereceptor4 (TLR4) + (−0.0528) × tumor necrosis factor receptor superfamily member 1A (TNFRSF1A) + (0.1208) × Enhancer of Zeste Homolog 2 (EZH2) + (−0.004) × N-myc Down-stream Regulated Gene 2 (NDRG2). EC patients can be divided into high-risk group and low-risk group based on the median riskscore and the high-risk group has a worse prognosis. Survival analysis showed a worse prognosis for patients in the high-risk group (p < 0.05). Immunomicroenvironment analysis showed a significant negative correlation between risk score and infiltration levels of B cells, CD4+ T cells, CD8+ T cells, Endothelial cells, macrophages, and NK cells. Subsequent cell experiments showed that knockdown of the key gene EZH2 in signature significantly reduced the invasion, migration and healing abilities of EC cell lines, proving that EZH2 is a promising marker of EC.","PeriodicalId":11903,"journal":{"name":"European journal of gynaecological oncology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136115276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 23 years old patient was admitted to Department of Operative Gynecology for treating malignant vulvar neoplasma.

A 2 cm exophytic lesion was noted ~10 mm from clitoris on right labia majora. Multifocal biopsy was performed for suspect finding which proved invasive vulvar squamous keratinizing cancer. Positron emission tomography-computed tomography (PET/CT) scan showed individual lymph nodes on right inguinofemoral region which were moderately metabolically active. Wide excision of cancer was performed with unilateral inguinofemoral lymphadenectomy.
