The RAS/MAPK signal transduction pathway is an intracellular signaling cascade that transmits environmental signals from activated receptor tyrosine kinases (RTKs) on the cell surface and other endomembranes to transcription factors in the nucleus. thereby linking extracellular stimuli to changes in gene expression. Largely as a consequence of its role in oncogenesis. RAS signaling ha... https://www.roneverhart.com/L-Homme-Ideal-Cologne-by-Guerlain/
