Staurosporine and cytochalasin D induce chondrogenesis by regulation of actin dynamics in different way

Kim M, Song K, Jin EJ, Sonn J

  • KMID: 1389731
  • Exp Mol Med.
  • 2012 Sep;44(9):521-528.
Actin cytoskeleton has been known to control and/or be associated with chondrogenesis. Staurosporine and cytochalasin D modulate actin cytoskeleton and affect chondrogenesis. However, the underlying mechanisms for actin dynamics regulation...

Effect of Palmitoyl-Pentapeptide (Pal-KTTKS) on Wound Contractile Process in Relation with Connective Tissue Growth Factor and α-Smooth Muscle Actin Expression

Park H, An E, Lee AR

To evaluate whether Palmitoyl-pentapeptide (Pal-KTTKS), a lipidated subfragment of type 1 pro-collagen (residues 212–216), plays a role in fibroblast contractility, the effect of Pal-KTTKS on the expression of pro-fibrotic mediators...

The Prognostic Significance of Fascin Expression in Colorectal Carcinoma

Lee JM, Lee JH, Roh MS, Park KJ

BACKGROUND/AIMS: Fascin, an actin-bundling protein found in membrane ruffles, microspikes, and stress fibers, induces membrane protrusions and increases cell motility in normal and various transformed cells. The expression of fascin...

An experimental study on the effect of cytoskeletal changes on osteoblastic cell activities

Lee JH, Nahm DS

  • KMID: 2141271
  • Korean J Orthod.
  • 1998 Dec;28(6):915-926.
The cytoskeleton has been shown to form a network, connecting the extracelluar matrix via integrin with the nucleus and the cytoplasmic constituents of the cell It is therefore assumed that...

Cyclic Stretch Effects on Adipose-Derived Stem Cell Stiffness, Morphology and Smooth Muscle Cell Gene Expression

Rabbani M, Tafazzoli-Shadpour M, Shokrgozar MA, Janmaleki , Teymoori M

Recent investigations consider adipose-derived stemcells (ASCs) as a promising source of stemcells for clinical therapies. To obtain functional cells with enhanced cytoskeleton and aligned structure, mechanical stimuli are utilized during...

Odontogenic Ameloblast-Associated Protein (Odam) Plays Crucial Roles in Osteoclast Differentiation via Control of Actin Ring Formation

Lee HK, Park JC

PURPOSE: In osteoclast differentiation, actin-rich membrane protrusions play a crucial role in cell adhesion. Odontogenic ameloblast-associated protein (Odam) contributes to cell adhesion by inducing actin rearrangement. Odam-mediated RhoA activity may...

Characterization of the Rho GTPase-Activating Protein RhoGAP68F

Nahm M, Lee S

Rho small GTPases control multiple aspects of neuronal morphogenesis by regulating the assembly and organization of the actin cytoskeleton. Although they are negatively regulated by GTPase activating proteins (GAPs), the...

Gene Expression Changes Associated with Sustained p16 Expression in Hepatocellular Carcinoma Cells

Oh SJ, Im JY, Jung CH, Lee YB

BACKGROUND: The normal functions of the cell cycle inhibitor p16INK4a are frequently inactivated in many human cancers. Over 80% of hepatocellular carcinoma (HCC) cases lack a functional p16/Rb pathway. p16/Rb...

Synovial fluid of patients with rheumatoid arthritis induces alpha-smooth muscle actin in human adipose tissue-derived mesenchymal stem cells through a TGF-beta1-dependent mechanism

Song HY, Kim MY, Kim KH, Lee IH, Shin SH, Lee JS, Kim JH

Rheumatoid arthritis (RA) is a chronic, inflammatory autoimmune disorder that causes the immune system to attack the joints. Transforming growth factor-beta1 (TGF-beta1) is a secreted protein that promotes differentiation of...
