15749814 Ke FC, Fang SH, Lee MT, Sheu SY, Lai SY, Chen YJ, Huang FL, Wang PS, Stocco DM, Hwang JJ: Lindane, a gap junction blocker, suppresses FSH and transforming growth factor beta1-induced connexin43 gap junction formation and steroidogenesis in rat granulosa cells. J Endocrinol. 2005 Mar;184(3):555-66.

Immunoblotting analysis showed that FSH plus TGF beta1 dramatically increased the levels of phosphorylated Cx43 without significantly influencing the level of nonphosphorylated Cx43, and this stimulatory effect was completely suppressed by lindane.

CONCLUSION: ChK's protective effects, both preventative and reversal, on lindane and dieldrin inhibition of gap junction-mediated communication are associated with stabilization and reappearance of the connexin 43 P2 phosphoform and may be mediated by the Akt pathway.

11532877 Defamie N, Mograbi B, Roger C, Cronier L, Malassine A, Brucker-Davis F, Fenichel P, Segretain D, Pointis G: Disruption of gap junctional intercellular communication by lindane is associated with aberrant localization of connexin43 and zonula occludens-1 in 42GPA9 Sertoli cells. Carcinogenesis. 2001 Sep;22(9):1537-42.

These results suggest that lindane inhibits GJIC between Sertoli cells and that aberrant Cx43/ZO-1 localization may be responsible for this effect.

Connexin43 (Cx43) is a gap junction protein that forms multimeric channels that enable intercellular communication through the direct transfer of signals and metabolites.

Treatment of WB-F344 rat liver epithelial cells with DDT (1,1-bis (p-chlorophenyl)-2,2,2-trichloroethane) or lindane induces a loss of gap junction plaques and a decrease in the phosphorylated gap junction protein connexin43-P2 (Cx43-P2), which is associated with the plaques.

Inhibition of ERK pathway by PD98059, a MEK1-specific inhibitor, prevented Lindane-induced Cx43 phosphorylation, restored Cx43 membranous localization and gap junction coupling.

Treatment of these cells with lindane, a general gap junction blocker, or expression of dominant negative Cx43 increased apoptotic cell death and decreased the level of integrin beta4 protein, in a manner similar to that observed when these cells were exposed to TGF-beta3.

Treatment of cultured chick embryos with lindane, which diminishes gap junctional communication, frequently unbiased normal LR asymmetry of Shh and Nodal gene expression, causing the normally left-sided program to be recapitulated symmetrically on the right side of the embryo.
A survey of early expression of connexin mRNAs revealed that Cx43 is present throughout the blastoderm at Hamburger-Hamilton stage 2-3, prior to known asymmetric gene expression.

Persistent heat treatment augmented Cx43 phosphorylation in a heat- and time-dependent fashion and this phosphorylation was recovered after heat shock.
First, we investigated whether the abolition of GJIC by lindane affects heat sensitivity in normal human cells.
