26820620 Genetic variants in CLDN2 and MORC4 genes were associated with chronic pancreatitis in Indian patients.
26568313 The authors conclude that claudin-2 forms gated paracellular channels.
26212084 The current study reveals an important and novel mechanism for VDR by regulation of epithelial barriers.
26110235 Association of claudin2 (rs7057398) polymorphism with idiopathic recurrent acute pancreatitis and progression of the disease to chronic pancreatitis.
26061016 Quercetin decreases claudin-2 expression mediated by up-regulation of miR-16 expression and instability of claudin-2 mRNA in lung adenocarcinoma cells.
26023235 Phosphorylation state of the tyrosine of claudin-1 and claudin-2 regulates interaction with ZO1.
25948735 TNF--alpha modifies claudin-2 expression in tubular cells and this can have both short-term and long-term effects on transport and barrier functions.
25823815 Pan-inhibition of SFK signaling pathways elevated Claudin-2 expression levels in breast cancer cells. Loss of Yes or Fyn induces Claudin-2 expression; whereas, diminished Lyn levels impairs Claudin-2 expression in breast cancer cells.
25694446 PKCiota binds to Rab14 and that PKCiota requires Rab14 for its correct distribution in cells. As with Rab14, PKCiota protects claudin-2 from lysosomal degradation and, in consequence, modulates epithelial barrier.
25616664 Autophagy reduces the paracellular permeability of small solutes and ions via degradation of the pore-forming tight junction protein claudin-2.
