17. The data of this study revealed Deletion of oligodendrocyte Cx32 and astrocyte Cx43 causes white matter vacuolation, astrocyte loss and early mortality.

18. oligodendrocyte-astrocyte gap junction coupling in Cx32 or Cx47 knockout mice. In corpus callosum, oligodendrocytes appeared to be directly coupled to other oligodendrocytes. O:O coupling was more affected in mice lacking Cx32 than in mice lacking Cx47.

19. Asn(175) of Cx32 is a critical residue for heterotypic docking and functional gap junction channel formation between the Cx32 and Cx26 hemichannels.

20. These findings suggest that altered Cx32 expression, a loss of intercellular Cx32 and a gain of intracytoplasmic Cx32 in the form of punctate "dot", plays an important role in the formation of gastric adenocarcinomas.

Human Gap Junction Protein, beta 1, 32kDa (GJB1) interaction partners

1. Cx32 expression may induce cisplatin resistance by modulating drug efflux transporter expression and activating the EGFRprotein kinase B signalling pathway in ovarian cancer cells.

2. EphB1 and EphA1 phosphorylate the Cx32CT domain residue Tyr(243) Unlike for Cx43, the tyrosine phosphorylation of the Cx32CT increased gap junction intercellular communication.

3. This study showed that an An 8-generation family with X-linked Charcot-Marie-Tooth: Confirmation Of the pathogenicity Of a 3' untranslated region mutation in GJB1.

4. Findings support the hypothesis that paracrine signalling alteration due to Cx32 hemichannel dysfunction underlies CMTX1 pathogenesis.

5. These "periferal nervous system-only" mutations form gap junction plaques and produce levels of junctional coupling similar to those for wild-type Cx32. In contrast, mutants with central nervous system manifestations either form no morphological gap junction plaques or, if they do, produce little or no detectable junctional coupling.

6. Results show that the GJB1 (connexin 32; Cx32) mutants R75P, R75Q and R75W display variable structural conformation and dynamic behavior compared to the native protein.

7. Point mutation of GJB1 gene, encoding connexin 32, is associated with X-linked Charcot-Marie-Tooth disease.

8. Cx32 regulates the sensitivity of hepatocellular carcinoma cells to doxorubicin via the Src/FAK signaling pathway

9. Study verifies that Cx32 exerts an inhibitory effect on extrinsic apoptosis in cervical cancer (CaCx) cells, and suggests that Cx32 may regulate the progression and micro-environment of CaCx cells.

10. Cx32 is essential for cell-cell interactions that facilitate driving hESCs through hepatic-lineage maturation.

11. Study provides a novel mechanism for Cx32's anti-apoptotic effect and provides a reasonable explanation for the pro-tumor effect of Cx32 in human cervical cancer cells.
