Elevated expression of Yes-associated protein (YAP1) involves in the pathogenesis of cervical cancer. Bioinformatics analysis showed a targeting relationship between miR-205 and the 3'-UTR of YAP1. In this study, we aim to explore the role of miR-205 in the proliferation, apoptosis, or cisplatin (CDDP) resistance of cervical cancer cells. The dual luciferase reporter gene assay verified the relationship between miR-205 and YAP1. The CDDP-resistant cell line Hela/CDDP cells were cultured and divided into miR-NC group, miR-205 mimic group, and miR-205 inhibitor group followed by analysis of the expression of miR-205 and YAP1 mRNA by quantitative real-time polymerase chain reaction (qRT-PCR), and YAP1 protein level by western blot. There was a targeted relationship between miR-205 and YAP1 mRNA. Compared with cervical cell line HCerEpiC cells, miR-205 expression was significantly decreased and YAP1 mRNA and protein expression was significantly increased in Hela cells ( < 0.01). Compared with miR-NC group, YAP1 protein expression in HeLa/CDDP cells was significantly decreased, cell apoptosis was increased, and proliferation was inhibited in miR-205 mimic-transfected Hela/CDDP cells ( < 0.01). Opposite results were obtained in miR-205 inhibitor-transfected Hela/CDDP cells. The expression of miR-205 is related to the CDDP resistance of cervical cancer cells. Increasing the expression of miR-205 can downregulate the expression of YAP1, inhibit the proliferation and promote apoptosis of cervical cancer cells, and enhance the sensitivity to CDDP.

5-Methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) are crucial epigenetic modifications in eukaryotic genomic DNA that regulate gene expression and are associated with the occurrence of various cancers. Here, we combined bisulfite conversion with 4-acetamido-2,2,6,6-tetramethyl-1-oxopiperridinium tetrafluoroborate (ACTBF, TCI) oxidation to develop a label-free and sequence-independent isothermal amplification (BTIA) assay for a genome-wide 5mC and 5hmC analysis. The BTIA strategy can distinguish 5mC and 5hmC signatures from other bases with high sensitivity and good specificity, avoiding sophisticated chemical modifications and expensive protein labeling.

This study examined the relationship between the vaginal microbiome, HPV infection, and cervical intraepithelial neoplasia (CIN) in 173 women. Subjects were grouped by HPV status and cervical lesion severity, ranging from HPV-negative to CIN Grade 2 or higher. Using VALENCIA classification, the study identified different community state types (CSTs) of vaginal microbiota, with CST IV subtypes (Staphylococcus dominated) showing high diversity and increased pathogenic bacteria.

Incorporating molecular testing for human papillomavirus (HPV) into the screening of cervical specimens can improve risk stratification and, in turn, patient management. Infection with a high-risk (HR) HPV genotype is associated with greater risk for persistent infection, viral integration, and progression of cervical neoplasia. Current guidelines consider HPV 16 or HPV 18 clinically actionable with referral to colposcopy; however, 12 Other HR HPV genotypes have been associated with cervical cancer risk, suggesting a benefit of extended genotyping.

Although breast, cervical, endometrial, and ovarian cancers account for more than 43% of new cases in 2023 in Brazilian women, no national studies were found on the incidence, risk factors, and prevention of breast and gynecological neoplasms in lesbian women, causing the health needs of non-heterosexual women to go unnoticed by professionals. This study aims to identify and analyze the search for healthcare related to the prevention of breast/gynecological cancer among Brazilian lesbian cisgender women who have not had the disease. Seven lesbian women participated in this qualitative study.

Objective: The goal of this study was to better understand the epidemiology, clinical characteristics, and treatment outcomes of head and neck sarcomas using real-world data from Japan.
Methods: Using the Japanese Head and Neck Cancer Registry, we identified 438 patients who were pathologically diagnosed with head and neck sarcoma between 2011 and 2020. We compared epidemiological, clinical, and prognostic data for the different histological types of sarcoma.
