Nordihydroguaiaretic acid (NDGA) blocks the differentiation of C2C12 myoblast cells

Nordihydroguaiaretic acid (NDGA) blocks the differentiation of C2C12 myoblast cells Addition of nordihydroguaiaretic acid (NDGA) to the differentiation medium of C2C12 mouse myoblast cells caused severe inhibition of the formation of myotubes and suppressed differentiation‐dependent elevation in the levels of the creatine kinase M isozyme (CKM). Under these conditions, NDGA did not cause significant increase of damaged cells, as detected by annexin‐V‐FITC assay, or induction of heat shock proteins, known to be a response against extracellular stress. The results suggest that NDGA itself is not toxic but can effectively blocks the differentiation‐dependent increase of CKM during C2C12 differentiation. The levels of muscle specific bHLH proteins MyoD, Myf5, and myogenin were also decreased by addition of NDGA, indicating a block of the initial step of the myogenesis through downregulation of muscle specific genes. NDGA is known to be a lipoxygenase inhibitor but other examples, like MK‐886 and CDC, did not exert the same effects on differentiation of muscle cells, indicating that mechanisms of NDGA action are independent of its influence on lipoxygenase. © 2004 Wiley‐Liss, Inc. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Cellular Physiology Wiley

Abstract

Addition of nordihydroguaiaretic acid (NDGA) to the differentiation medium of C2C12 mouse myoblast cells caused severe inhibition of the formation of myotubes and suppressed differentiation‐dependent elevation in the levels of the creatine kinase M isozyme (CKM). Under these conditions, NDGA did not cause significant increase of damaged cells, as detected by annexin‐V‐FITC assay, or induction of heat shock proteins, known to be a response against extracellular stress. The results suggest that NDGA itself is not toxic but can effectively blocks the differentiation‐dependent increase of CKM during C2C12 differentiation. The levels of muscle specific bHLH proteins MyoD, Myf5, and myogenin were also decreased by addition of NDGA, indicating a block of the initial step of the myogenesis through downregulation of muscle specific genes. NDGA is known to be a lipoxygenase inhibitor but other examples, like MK‐886 and CDC, did not exert the same effects on differentiation of muscle cells, indicating that mechanisms of NDGA action are independent of its influence on lipoxygenase. © 2004 Wiley‐Liss, Inc.
