Estradiol regulates miR-135b and mismatch repair gene expressions via estrogen receptor-beta in colorectal cells

He YQ, Sheng JQ, Ling XL, Fu L, Jin P, Yen L, Rao J

  • KMID: 1402316
  • Exp Mol Med.
  • 2012 Dec;44(12):723-732.
Estrogen has anti-colorectal cancer effects which are thought to be mediated by mismatch repair gene (MMR) activity. Estrogen receptor (ER) expression is associated with microRNA (miRNA) expression in ER-positive tumors....
