Keratinocyte Proliferation (Suppression)

Keratinocyte proliferation refers to the process by which keratinocytes, the predominant cell type in the epidermis, divide and multiply. Suppression of this proliferation is a key therapeutic target in conditions characterized by excessive skin cell growth, such as psoriasis and certain skin cancers. Key signaling pathways involved include PKC, mTOR, MAPK/AP1, and PI3K/AKT/mTOR/NFκB. Agents that upregulate cell cycle inhibitors (e.g., p21^Cip1^) or disrupt cellular metabolism can effectively suppress keratinocyte proliferation.

Inhibition of keratinocyte proliferation through various mechanisms, including cell cycle arrest, modulation of signaling pathways (MAPK, PI3K/AKT/mTOR, PKC), and metabolic disruption.
