Molecular imaging of membrane proteins and microfilaments using atomic force microscopy

Jung SH, Park D, Park JH, Kim YM, Ha KS

Atomic force microscopy (AFM) is an emerging technique for a variety of uses involving the analysis of cells. AFM is widely applied to obtain information about both cellular structural and...

Sulfuretin protects against cytokine-induced beta-cell damage and prevents streptozotocin-induced diabetes

Song MY, Jeong GS, Kwon KB, Ka SO, Jang HY, Park JW, Kim YC, Park BH

NF-kappaB activation has been implicated as a key signaling mechanism for pancreatic beta-cell damage. Sulfuretin is one of the main flavonoids produced by Rhus verniciflua, which is reported to inhibit...

TGF-beta1 induces mouse dendritic cells to express VEGF and its receptor (Flt-1) under hypoxic conditions

Nam EH, Park SR, Kim PH

Angiogenesis is a multi-step process that involves the activation, proliferation, and migration of endothelial cells. We have recently shown that TGF-beta1 can induce mouse macrophages to produce VEGF, a potent...

Transglutaminase 2 inhibits apoptosis induced by calciumoverload through down-regulation of Bax

Cho SY, Lee JH, Bae HD, Jeong EM, Jang GY, Kim CW, Shin DM, Jeon JH, Kim IG

An abrupt increase of intracellular Ca2+ is observed in cells under hypoxic or oxidatively stressed conditions. The dysregulated increase of cytosolic Ca2+ triggers apoptotic cell death through mitochondrial swelling and...

Phosphatidylinositol 4-phosphate 5-kinase alpha is induced in ganglioside-stimulated brain astrocytes and contributes to inflammatory responses

Lee SY, Kim B, Yoon S, Kim YJ, Liu T, Woo JH, Chwae YJ, Joe EH, Jou I

In brain tissue, astrocytes play defensive roles in central nervous system integrity by mediating immune responses against pathological conditions. Type I phosphatidylinositol 4-phosphate 5-kinase alpha (PIP5Kalpha) that is responsible for...

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...

Change in serum proteome during allogeneic hematopoietic stem cell transplantation and clinical significance of serum C-reactive protein and haptoglobin

Ryu J, Lee SR, Park SG, Kang S, Kim HJ, Park BC

Successful hematopoietic stem cell transplantation (HSCT) involves the restoration of hematopoietic function after engraftment, arising from the differentiation and proliferation of hematopoietic stem cells. Several factors could influence the course...
