The regulation of radiation and cytokines to p21 gene expression
-
Abstract
p21 gene is a negative regulator of cell cycle, which affect cell cycle progression arrest at G1 and G2 by some factors induced. p21 gene plays an important role to maintain genomic stability. Radiation and TGFβ1, TNFα, PTEN, IGF can increase p21 gene expression, however E1A, c-jun, Tbx2, PLD1 and PLD2 can inhibit p21 gene expression.
