Objective: To study the effects of acute cold stress on connexin43 (Cx43) protein expression with drug intervention, and cell to cell conduction with its mechanism in neonatal rats’ myocardial cells.
Methods: The primary neonatal rats’ myocardial cell culture was conducted in 4 groups. Group① , the cells were normally cultured, Group②, the cells were cultured at 4℃, Group③, the cells were cultured at 0℃and Group④, the anti-arrhythmia peptide (AAP 10) was added in Group②and Group③. The apoptosis rate of myocardial cells was evaluated by lfow cytometry assay, mRNA and protein expressions of CX43 were examined by RT-PCR and Western blot analysis, and CX43 phosphorylation product (P-CX43) was detected.
Results: Compared with normally cultured cells, the myocardial cell apoptosis rate was obviously increased by acute cold stress at 4℃and 0℃with time extension. The mRNA expression of Cx43 was decreased at varying degrees at 4℃and 0℃stimulation, the protein expression of Cx43 was decreased at varying degrees at 4℃and 0℃stimulation with time extension, and P-Cx43 level was decreased. While the APP 10 intervention may obviously elevate the protein levels of Cx43 and P-Cx43.
Conclusion: Acute cold stress could reduce the protein expression of CX43 and P-CX43, while APP 10 intervention may elevate such expression and improve the cell to cell conduction in neonatal rats’ myocardial cells.

AIM: To investigate the potential role of 14-3-3 tau in trophoblast cells on invasiveness. METHODS: 14-3-3 tau expression was detected in first-trimester villi, deciduas and human trophoblastic cell line (BeWo) by immunohistochemistry. Small interference RNA (siRNA) targeting 14-3-3 tau was transfected into BeWo cells. The effects of down-regulated 14-3-3 tau on invasion of human trophoblasts cell line BeWo were examined by matrigel invasion assay, and the transcription, translation of E-cadherin and snail were estimated by RT-PCR or Western blotting. U0126 was used to detect the extracellular-signal related kinase 1/2 (ERK1/2) function on down-regulation of 14-3-3 tau induced cell invasion. RESULTS: 14-3-3 tau was detected in the invasive trophoblastic cells in the first trimester villi and that invaded to the deciduas. BeWo cells also expressed 14-3-3 tau. Down-regulation of 14-3-3 tau increased the invasive cell-number of BeWo, as well as the expression of snail, and inhibited E-cadherin. U0126 inhibited the enhanced invasiveness in these cells induced by the down-regulation of 14-3-3 tau. CONCLUSION: 14-3-3 tau may regulate the invasiveness of human trophoblastic cells through ERK1/2 signaling pathway.
