Cellular proliferation pathway

The cellular proliferation pathway encompasses the complex network of biochemical signals that regulate the growth, maturation, and division of cells. These pathways, most notably the MAPK/ERK and PI3K/Akt/mTOR cascades, integrate signals from growth factors and the extracellular matrix to coordinate the cell cycle and metabolic activities [1][2]. Under physiological conditions, these processes are strictly controlled to ensure tissue integrity and proper development. However, the dysregulation or constitutive activation of these pathways is a primary driver of malignancy, allowing cancer cells to bypass normal growth checkpoints [3]. Beyond oncology, overactive proliferative signaling contributes to conditions such as psoriasis, pulmonary fibrosis, and various autoimmune disorders [4]. Therapeutic strategies frequently employ small molecule inhibitors or monoclonal antibodies to target specific nodes within these pathways, such as receptor tyrosine kinases or cyclin-dependent kinases, to halt pathological cell expansion [5].
