Renal claudin-14 expression is not required for regulating Mg<sup>2+</sup> balance in mice

چکیده

Using transgenic models and in vitro assays, this study examined the effect of Mg 2+ on regulating urinary excretion Ca via activation -sensing receptor-claudin 14 (CLDN14) pathway. The suggests that CLDN14 is unlikely to play a significant role compensatory response hypermagnesemia.

Claudin-16 and claudin-19 interaction is required for their assembly into tight junctions and for renal reabsorption of magnesium.

Claudins are tight junction integral membrane proteins that are key regulators of the paracellular pathway. Defects in claudin-16 (CLDN16) and CLDN19 function result in the inherited human renal disorder familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC). Previous studies showed that siRNA knockdown of CLDN16 in mice results in a mouse model for FHHNC. Here, we show that C...

Ezh2 is not required for cardiac regeneration in neonatal mice

The neonatal mouse heart has the remarkable capacity to regenerate lost myocardium within the first week of life. Neonatal cardiomyocytes re-express fetal genes that control cell proliferation after injury to promote regeneration. The loss of regenerative capacity of the heart one week after birth coincides with repression of a fetal transcriptional program coordinated by epigenetic regulators....

Rabphilin knock-out mice reveal that rabphilin is not required for rab3 function in regulating neurotransmitter release.

Rab3A and rab3C are GTP-binding proteins of synaptic vesicles that regulate vesicle exocytosis. Rabphilin is a candidate rab3 effector at the synapse because it binds to rab3s in a GTP-dependent manner, it is co-localized with rab3s on synaptic vesicles, and it dissociates with rab3s from the vesicles during exocytosis. Rabphilin contains two C(2) domains, which could function as Ca(2+) sensors...

The IgCAM CLMP is required for intestinal and ureteral smooth muscle contraction by regulating Connexin43 and 45 expression in mice

The function of the IgCAM CLMP which is implicated in congenital short-bowel syndrome in humans was studied in mice. Although the levels of mRNAs encoding Connexin43 or 45 are not or only marginally affected, respectively, absence of CLMP caused a severe reduction of both proteins in smooth muscle cells of the intestine and of Connexin43 in the ureter. Analysis of calcium signaling revealed a d...
