RASSF1A Suppresses Cell Migration through Inactivation of HDAC6 and Increase of Acetylated alpha-Tubulin

Jung HY, Jung JS, Whang YM, Kim YH

  • KMID: 2167619
  • Cancer Res Treat.
  • 2013 Jun;45(2):134-144.
PURPOSE: The RAS association domain family protein 1 (RASSF1) has been implicated in a tumor-suppressive function through the induction of acetylated alpha-tubulin and modulation of cell migration. However, the mechanisms...

Synergistic induction of cancer cell migration regulated by Gbetagamma and phosphatidylinositol 3-kinase

Kim EK, Yun SJ, Ha JM, Kim YW, Jin IH, Woo DH, Lee HS, Ha HK, Bae SS

  • KMID: 1387359
  • Exp Mol Med.
  • 2012 Aug;44(8):483-491.
Phosphatidylinositol 3-kinase (PI3K) is essential for both G protein-coupled receptor (GPCR)- and receptor tyrosine kinase (RTK)-mediated cancer cell migration. Here, we have shown that maximum migration is achieved by full...

5-Formylhonokiol exerts anti-angiogenesis activity via inactivating the ERK signaling pathway

Zhu W, Fu A, Hu J, Wang T, Luo Y, Peng M, Ma Y, Wei Y, Chen L

Our previous report has demonstrated that 5-formylhonokiol (FH), a derivative of honokiol (HK), exerts more potent anti-proliferative activities than honokiol in several tumor cell lines. In present study, we first...

Co-treatment with hepatocyte growth factor and TGF-beta1 enhances migration of HaCaT cells through NADPH oxidase-dependent ROS generation

Nam HJ, Park YY, Yoon G, Cho H, Lee JH

Wound healing requires re-epithelialization from the wound margin through keratinocyte proliferation and migration, and some growth factors are known to influence this process. In the present study, we found that...
