The Effect of HIF-1alpha siRNA on Growth and Chemosensitivity of Mia-paca Cell Line

Yang L, Kang WK

PURPOSE: Hypoxia-inducible factor-1alpha (HIF-1alpha) primarily mediates the hypoxic response. HIF-1alpha induction by various stimuli contributes to cell proliferation and survival. To investigate the effect of HIF-1alpha, we used small interfering...

Increased Intestinal Epithelial Cell Turnover and Intestinal Motility in Gymnophalloides seoi-Infected C57BL/6 Mice

Lee SH, Jung BK, Park JH, Shin EH, Chai JY

  • KMID: 1792181
  • Korean J Parasitol.
  • 2014 Jun;52(3):273-280.
The changing patterns of goblet cell hyperplasia, intestinal epithelial cell turnover, and intestinal motility were studied in ICR and C57BL/6 mice infected with Gymnophalloides seoi (Digenea: Gymnophallidae). Whereas ICR mice...

The roles of glycosphingolipids in the proliferation and neural differentiation of mouse embryonic stem cells

Jung JU, Ko K, Lee DH, Ko K, Chang KT, Choo YK

Glycosphingolipids including gangliosides play important regulatory roles in cell proliferation and differentiation. UDP-glucose:ceramide glucosyltransferase (Ugcg) catalyze the initial step in glycosphingolipids biosynthesis pathway. In this study, Ugcg expression was reduced...

Enhanced proliferation and differentiation of Oct4- and Sox2-overexpressing human adipose tissue mesenchymal stem cells

Han SM, Han SH, Coh YR, Jang G, Chan Ra J, Kang SK, Lee HW, Youn HY

Mesenchymal stem cells (MSCs) are attractive candidates for clinical repair or regeneration of damaged tissues. Oct4 and Sox2, which are essential transcription factors for pluripotency and self-renewal, are naturally expressed...

Grading of Histology, Expression of Apoptosis and Cell Proliferation in Gastric Mucosa Adjacent to Gastric Adenoma or Adenocarcinoma

Jung JT, Lee CH, You SS, Ha HK, Bae JS, Kwon JG, Kim EY, Kim HG, Cho CH, Shin IH

  • KMID: 772843
  • Korean J Gastroenterol.
  • 2005 Oct;46(4):269-275.
BACKGROUND/AIMS: Helicobacter pylori (H. pylori) infection can lead to gastric adenoma and carcinoma through atrophic gastritis and intestinal metaplasia. Imbalance between apoptosis and proliferation may play a role in gastric...

TGF-beta1-induced PINCH-1-ILK-alpha-parvin complex formation regulates mesangial cell proliferation and hypertrophy

Kim SM, Kim N, Lee S, Kim DK, Lee YM, Ahn SH, Song JH, Choi BK, Wu C, Jung KY

  • KMID: 756075
  • Exp Mol Med.
  • 2007 Aug;39(4):514-523.
TGF-beta1-induced glomerular mesangial cell (GMC) injury is a prominent characteristic of renal pathology in several kidney diseases, and a ternary protein complex consisting of PINCH-1, integrin-linked kinase (ILK) and alpha-parvin...

TRPC3 cation channel plays an important role in proliferation and differentiation of skeletal muscle myoblasts

Woo JS, Cho CH, Kim DH, Lee EH

During membrane depolarization associated with skeletal excitation-contraction (EC) coupling, dihydropyridine receptor [DHPR, a L-type Ca2+ channel in the transverse (t)-tubule membrane] undergoes conformational changes that are transmitted to ryanodine receptor...

Enhanced skin wound healing by a sustained release of growth factors contained in platelet-rich plasma

Yang HS, Shin J, Bhang SH, Shin JY, Park J, Im GI, Kim CS, Kim BS

Platelet-rich plasma (PRP) contains growth factors that promote tissue regeneration. Previously, we showed that heparin-conjugated fibrin (HCF) exerts the sustained release of growth factors with affinity for heparin. Here, we...
