Unveiling hsa_circ_0007439: a novel suppressor of nasopharyngeal carcinoma via miR-556-5p/PTEN Axis.

Objective: There has been no explanation for the exact mechanism of circRNAs in nasopharyngeal carcinoma (NPC). Circ_0007439 was investigated in this study to determine its role and mechanism in NPC.

Methods: To identify circ_0007439, microRNA (miR)-556-5p, and PTEN mRNA in NPC tissues and cells, RT-qPCR was employed.

A novel prognostic signature and therapy guidance for hepatocellular carcinoma based on STEAP family.

Background: The six-transmembrane epithelial antigen of prostate (STEAP) family members are known to be involved in various tumor-related biological processes and showed its huge potential role in tumor immunotherapy.

Methods: Biological differences were investigated through Gene set enrichment analysis (GSEA) and tumor microenvironment analysis by CIBERSORT. Tumor mutation burden (TMB), immunotherapy response and chemotherapeutic drugs sensitivity were estimated in R.

Comparative study on gene expression in psoriatic lesions versus chronic wound healing processes.

Psoriasis and chronic ulcers not only significantly impair quality of life but also pose a challenge in dermatological treatment. This study aimed to identify new therapeutic targets and biomarkers for psoriasis and chronic ulcers by comparing their gene expression profiles. The gene expression profiles of psoriatic, wound and chronic ulcer patients, as well as healthy controls, were determined via RNA extraction and next-generation sequencing of biopsies.

Design, synthesis and biological evaluation of 4-(4-aminophenoxy)picolinamide derivatives as potential antitumor agents.

Cancer is a leading cause of death in humans. Molecular targeted therapy for cancer has become a research hotspot as it is associated with low toxicity and high efficiency. In this study, a total of 36 derivatives of 4-(4-aminophenoxy)pyridinamide were designed and synthesized, based on the analysis of the binding patterns of cabozantinib and BMS-777607 to MET protein.

Design, synthesis and biological evaluation of novel 4-(pyrrolo[2,3-d]pyrimidine-4-yloxy)benzamide derivatives as potential antitumor agents.

Cancer is a major cause of death worldwide. Small molecule inhibitors have become a major therapeutic treatment for cancer. In this study, a series of novel 4-(pyrrolo[2,3-d]pyrimidine-4-yloxy)benzamide derivatives were designed, synthesized and evaluated for their antitumor activity against the A549, Hela and MCF-7 cell lines.
