Investigates leptin's effects on gene expression in triple-negative breast cancer cells, indicating potential therapeutic targets related to obesity and race.
Key Points
The research aims to understand how leptin affects gene expression in triple-negative breast cancer, particularly among different racial backgrounds.
Performed mRNA sequencing on TNBC cell lines from White (MDA-MB-231) and Black (MDA-MB-468) patients.
Conducted bioinformatics and pathway analyses to identify differentially-expressed genes (DEGs).
Measured gene expression changes after leptin treatment in both cell lines.
Identified 1,857 DEGs in MDA-MB-231 and 1,242 DEGs in MDA-MB-468 cells (P < 0.05).
Noted significant differences in pathway activation between cell lines when treated with leptin, indicating cell type-specific responses.
Suggested that targeting leptin pathways could help manage obesity-related breast cancer risks.
