Introduction

Gene expression and cellular signaling are central areas of modern cell biology because changes in transcriptional regulation, signaling proteins, receptor activity, and downstream molecular pathways can influence cellular proliferation, differentiation, survival, and programmed cell death. Research addressing these mechanisms frequently combines molecular biology, biochemical assays, cellular models, and experimental disease models. [5]
