Pentamidine, an antiprotozoal agent, has been traditionally known to cause QT prolongation and arrhythmias; however, its ionic mechanism not illustrated. In a stable HEK-293 cell line, we observed concentration-dependent inhibition of the hERG current with IC50 252 microM. freshly isolated guinea-pig ventricular myocytes, pentamidine showed no effect on L-type calcium at concentrations up 300 microM, slight action potential duration this concentration. Since effective channel APD were much...

Friedreich's ataxia is a rare disorder resulting from deficiency of frataxin, mitochondrial protein implicated in the synthesis iron-sulfur clusters. Preclinical studies mice have shown that gene therapy promising approach to treat individuals with ataxia. However, recent report provided evidence AAVrh10-mediated overexpression frataxin could lead cardiotoxicity associated dysfunction. While evaluating an AAV9-based using chicken β-actin promoter, we showed toxic be reached mouse liver and...

Polycystic ovary syndrome (PCOS), characterised by polycystic ovarian morphology, follicular maturation arrest, and hormonal disorders, affects numerous women in the reproductive age worldwide. A recent study has found that mitochondria are likely to play an essential role oocyte quality. However, it is still unclear whether development failure associated with patients PCOS. We analysed single-cell RNA sequencing data from previous study, including 14 oocytes 7 healthy fertile 20 9 PCOS at...

The Mediator complex (MED) functions as a co-activator in plants, transmitting transcriptional signals to regulate gene expression, including responses environmental stresses. While the MED family has been identified several species, it not yet reported cassava. In this study, we 32 members of MeMED cassava (Manihot esculenta Crantz) distributed across 13 chromosomes. These genes were categorized into distinct subunits based on their similarity Arabidopsis modules. Promoter analysis revealed...

Sustained, high level transgene expression in mammalian cells is desired many cases for studying gene functions. Traditionally, stable has been accomplished by using retroviral or lentiviral vectors. However, such viral vector-mediated often at low levels and can be reduced over time due to copy numbers and/or chromatin remodeling repression. The piggyBac transposon emerged as a promising non-viral vector system efficient transfer into cells. Despite its inherent advantages systems, not...
