Platinum agents are widely used in the chemotherapy of testicular cancer. However, adverse reactions and resistance to such agents have limited their application in antineoplastic treatment. The aim of the present study was to determine the role of gap junction intercellular communication (GJIC) composed of Cx43 on oxaliplatin‑induced survival/apoptosis in mouse leydig normal and cancer cells u...
The cytoplasmic N-termini of connexins have been implicated in protein trafficking, oligomerization and channel gating. To elucidate the role of the N-terminus in connexin37 (CX37), we studied mutant constructs containing partial deletions of its 23 N-terminal amino acids and a construct with a complete N-terminus in which residues 2-8 were replaced with alanines. All mutants containing nine or...
Several independent lines of investigation indicate that intercellular communication through gap junctions modulates bladder physiology and, moreover, that altered junctional communication may contribute to detrusor overactivity. However, as far as we are aware, there are still no direct recordings of gap junction-mediated intercellular currents between human or rat detrusor myocytes. Northern ...
The protein constituents of gap junctions, connexins, have a rapid basal rate of degradation even after transport to the cell surface. We have used cell surface biotinylation to label gap junction-unassembled plasma membrane pools of connexin43 (Cx43) and show that their degradation is inhibited by mild hyperthermia, oxidative stress, and proteasome inhibitors. Cytosolic stress does not perturb...
The process of atresia is an all-or-none phenomenon in that an entire follicle either undergoes atresia or continues along the developmental pathway. The absence of pockets of atresia adjacent to healthy areas of granulosa cells suggests the existence of a coordinating influence within the entire follicular unit during the process of atresia. Gap junctions interconnect the granulosa cells and t...
