Epithelial ovarian carcinoma (EOC) is the most lethal gynecologic malignancy. However, the molecular mechanisms remain unclear. In this study, we found that miR-146b was downregulated in EOC and its expression level was negatively correlated with the pathological staging. Follow-up functional experiments illustrated that overexpression of miR-146b significantly inhibited cell migration and invasion, and increased cell proliferation, but it also improved the response to chemotherapeutic agents. Mechanistically, we demonstrated that miR-146b exerted its function mainly through inhibiting F-box and leucine-rich repeat protein 10 (FBXL10), and upregulated the Cyclin D1, vimentin (VIM), and zona-occludens-1 (ZO-1) expression in EOC. These findings indicate that miR-146b-FBXL10 axis is an important epigenetic regulation pathway in EOC. Low miR-146b may contribute to cancer progression from primary stage to advanced stage, and may be the promising therapeutic target of EOC.

Lung cancer represents a significant global health burden, with non-small cell lung cancer (NSCLC) being the most common subtype. The current standard of care for NSCLC has limited efficacy, highlighting the necessity for innovative treatment options. Lidocaine, traditionally recognized as a local anesthetic, has emerged as a compound with potential antitumor and anti-inflammatory capabilities.

The Warburg effect, a common feature of solid tumors, rewires the metabolism and promotes growth, survival, proliferation, and long-term maintenance in gastric cancer (GC). We performed in vitro and in vivo studies of the pathogenesis of GC to investigate the effects and mechanism of LINC01224 in this cancer. qRT-PCR was used to measure the expression of LINC01224 or miR-486-5p in GC cells, and the expression of LINC01224 in GC tissues by FISH (Fluorescence in situ hybridization) analysis was evaluated.

Background: Cervical cancer is the fourth most common cancer worldwide in females. This occurs primarily due to the infection of high-risk Human Papilloma Virus (HPV), although in advanced stages it requires support from host cellular factors. BRN3A is one such host cellular factors, whose expression remains high in cervical cancers and upregulates tumorigenic HPV gene expression.
