Application
Cell cycle studies
A431 Cell Line human has been used:
to demonstrate that p38 mitogen-activated protein kinase enhances epidermal growth factor-induced apoptosis in A431 cells
to study melanoma-specific CD44 (a tumor marker and transmembrane receptor) alternative splicing pattern in A431 cells
to study the anti-cancer activity of antioxidant-rich Cameroonian medicinal plants
