['Does elevated temperature-induced cystic fibrosis transmembrane conductance regulator (CFTR) down-regulation in Sertoli cells in cryptorchid testis disrupt testicular tight junctions (TJs) through the nuclear factor kappa B (NF-κB)/cyclooxygenase-2 (COX-2)/prostaglandin E(2) (PGE(2)) pathway?'] Does cryptorchidism-induced CFTR down-regulation result in disruption of testicular tight junctions through up-regulation of NF-κB/COX-2/PGE2?
