Dr. Anvar Soleimani, a lecturer and Researcher at the Department of Medical Microbiology, College of Health Sciences, Cihan University-Sulaimaniya, has published an article in the esteemed Journal of Molecular and Cellular Biochemistry. This Review article provides a comprehensive analysis of molecular mechanisms that sustain MAPK activation and promote tamoxifen resistance. Tamoxifen remains a standard treatment for estrogen receptor (ER)-positive breast cancer. However, many patients develop resistance, even without changes to the ER itself. The research highlights how persistent MAPK signalling, driven by factors such as growth factors, RNA-binding proteins, microRNAs, and mitochondrial changes, enables cancer cells to evade tamoxifen’s effects. The study also discusses how MAPK, in cooperation with other survival pathways like PI3K/AKT and receptor tyrosine kinases (EGFR, IGF-1R, FGFR), creates redundant networks that promote tumor survival. Importantly, the authors identify potential therapeutic strategies, including MAPK-targeting drugs and RNA-based treatments, that may help overcome this resistance.
