Abstract
Lung cancer (LC) accounts for approximately 25% of all cancer cases, with 80-85% of these being non-small cell lung cancer (NSCLC). VS-5584 is a novel anti-cancer agent that specifically inhibits mTORC1/2 and class I PI3K isoforms. There is cross-talk between the PI3K-Akt-mTOR and WNT signaling pathways that are abnormally activated in NSCLC. In this study, we aimed to evaluate the anti-cancer effects of VS-5584 on A549 lung adenocarcinoma cells and changes in WNT signaling gene expression in vitro, while also correlating differentially expressed genes in silico. The effect of VS-5584 on A549 cell viability was assessed by the MTT assay. Apoptosis and cell cycle profiles were analyzed by flow cytometry, while WNT signaling gene expression was measured by quantitative RT-PCR. Differentially expressed genes (DEGs) in the TCGA LUAD and LUSC datasets were identified using the GEPIA2 platform. VS-5584 treatment induced apoptosis and caused cell cycle arrest at the G0/G1 phase in A549 cells. The mRNA expression levels of WNT signaling genes significantly decreased in treated cells. The expression of some upregulated DEGs in the datasets decreased in A549 cells treated with VS-5584. VS-5584 shows promise as an anti-cancer agent in the treatment of NSCLC by downregulating the expression of WNT signaling genes.
期刊介绍：
Cell Biochemistry and Biophysics (CBB) aims to publish papers on the nature of the biochemical and biophysical mechanisms underlying the structure, control and function of cellular systems
The reports should be within the framework of modern biochemistry and chemistry, biophysics and cell physiology, physics and engineering, molecular and structural biology. The relationship between molecular structure and function under investigation is emphasized.
Examples of subject areas that CBB publishes are:
· biochemical and biophysical aspects of cell structure and function;
· interactions of cells and their molecular/macromolecular constituents;
· innovative developments in genetic and biomolecular engineering;
· computer-based analysis of tissues, cells, cell networks, organelles, and molecular/macromolecular assemblies;
· photometric, spectroscopic, microscopic, mechanical, and electrical methodologies/techniques in analytical cytology, cytometry and innovative instrument design
For articles that focus on computational aspects, authors should be clear about which docking and molecular dynamics algorithms or software packages are being used as well as details on the system parameterization, simulations conditions etc. In addition, docking calculations (virtual screening, QSAR, etc.) should be validated either by experimental studies or one or more reliable theoretical cross-validation methods.
