Disease relevance of Cldn5

 

High impact information on Cldn5

 

Biological context of Cldn5

  • This suggests that reduced expression of claudin-5 plays a crucial role in the increased ovarian vascular permeability seen in OHSS and that its expression can be modulated by GnRHa treatment [1].
 

Anatomical context of Cldn5

 

Associations of Cldn5 with chemical compounds

  • To clarify the biological significance of this site in regulation of endothelial barrier functions, we established rat lung endothelial (RLE) cells expressing doxycycline (Dox)-inducible wild-type claudin-5 and a mutant with a substitution of Ala for Thr(207) (CL5T207A) [4].
  • We show that induction of wild-type claudin-5 is sufficient to reconstitute the paracellular barrier against inulin (5 kDa), but not mannitol (182 Da), in leaky RLE cells [4].
  • Hyperstimulation and a gonadotropin-releasing hormone agonist modulate ovarian vascular permeability by altering expression of the tight junction protein claudin-5 [1].
 

Regulatory relationships of Cldn5

 

Other interactions of Cldn5

  • Presumably, some of these proteins (e.g., occludin, claudin-5 and ZO-1) could be considered sensitive indicators of normal and also of disturbed functional state of the BBB [10].
  • This study investigates the effect in the rat of chronic CdCl2 intoxication (500 microg Cd2+/kg, daily i.p. injection for 5 days) on renal function and the changes in tight junction proteins claudin-2, claudin-3, and claudin-5 present in rat kidney [11].
  • Alteration of BBB related genes, such as those encoding p-glycoprotein, aquaporin-4, and claudin-5, was assessed at the protein and mRNA levels in the brain after local exposure of the head to EMF at 0, 2, and 6 W/kg specific energy absorption rates (SARs) for 90 min/day for 1 or 2 weeks [12].
