Impaired Activity of Ryanodine Receptors Contributes to Calcium Mishandling in Cardiomyocytes of Metabolic Syndrome Rats
Conclusion Principal findings of this work are that abnormal Ca2+ transient amplitude, contractile dysfunction; and impaired relaxation of MetS cardiomyocytes underlies intrinsic dysfunctional RyR2 and SERCA pump. Abnormal activity of RyRs was evidenced by its decreased ability to bind [3H]-ryanodine. Although the MetS condition does not modify RyR2 protein expression, its phosphorylation at Ser2814 is decreased, which impairs its capacity for activation during ECC. The dysfunctional RyRs, together with a decreased activity of SERCA pump due to decreased Thr17-PLN phosphorylation suggest a downregulation of CaMKII in MetS...

A Novel Variant in Non-coding Region of GJB1 Is Associated With X-Linked Charcot-Marie-Tooth Disease Type 1 and Transient CNS Symptoms
Conclusion A novel GJB1 variant of c.-170T>G in non-coding region was found in this big Chinese CMTX1 pedigree. This is the first report of variant in non-coding DNA sequence associated with transient CNS symptoms. Thyroid malfunction may contribute to the CNS symptoms in this case. Ethics Statement This study has been reviewed and approved by the Ethics Committee of the China-Japan Union Hospital of Jilin University. Each member of the family provided written informed consent to the participation in the study, the genetic test, and authorized to publish the study including the photos in accordance with the Decl...
