Dual regulatory effects of PI(4,5)P2 on TREK-2 K+ channel through antagonizing interaction between the alkaline residues (K330. and R355-357 ) in the cytosolic C-terminal helix

Kim SE, Kim MH, Woo J, Kim SJ

TWIK-related two-pore domain K+ channel-2 (TREK-2) has voltageindependent activity and shows additional activation by acidic intracellular pH (pH i ) via neutralizing the E332 in the cytoplasmic C terminal (Ct)....

The agonistic action of URO-K10 on Kv7.4 and 7.5 channels is attenuated by co-expression of KCNE4 ancillary subunit

Lee JE, Park CH, Kang H, Ko J, Cho S, Woo J, Chae MR, Lee SW, Kim SJ, Kim J, So I

KCNQ family constitutes slowly-activating potassium channels among voltage-gated potassium channel superfamily. Recent studies suggested that KCNQ4 and 5 channels are abundantly expressed in smooth muscle cells, especially in lower urinary...

Layer-specific serotonergic induction of long-term depression in the prefrontal cortex of rats

Shin D, Cho KH, Joo K, Rhie DJ

Layer 2/3 pyramidal neurons (L2/3 PyNs) of the cortex extend their basal dendrites near the soma and as apical dendritic tufts in layer 1, which mainly receive feedforward and feedback...

Nanoscale imaging of rat atrial myocytes by scanning ion conductance microscopy reveals heterogeneity of T-tubule openings and ultrastructure of the cell membrane

Park SH, Kim A, An J, Cho HS, Kang TM

In contrast to ventricular myocytes, the structural and functional importance of atrial transverse tubules (T-tubules) is not fully understood. Therefore, we investigated the ultrastructure of T-tubules of living rat atrial...

2,3,5,4’-Tetrahydroxystilbene-2-O-β-D-Glucoside modulated human umbilical vein endothelial cells injury under oxidative stress

Guo Y, Fan W, Cao S, Xie Y, Hong J, Zhou H, Wan H, Jin B

Endothelial cell injury is a major contributor to cardiovascular diseases. The 2,3,5,4’-Tetrahydroxystilbene-2-O-β-D-Glucoside (TSG) contributes to alleviate human umbilical vein endothelial cells (HUVECs) injury through mechanisms still know a little. This study...

Direct reprogramming of fibroblasts into diverse lineage cells by DNA demethylation followed by differentiating cultures

Yang DW, Moon J, Ko HM, Shin YK, Fukumoto S, Kim SH, Kim MS

Direct reprogramming, also known as a trans-differentiation, is a technique to allow mature cells to be converted into other types of cells without inducing a pluripotent stage. It has been...
