Aminoglycoside antibiotics (Figs. 1 and 2), containing a unique polyamine/ carbohydrate structure, have attracted considerable attention because of their specific interactions with RNA. Their antibacterial activity is mainly exerted by their binding to the RNA of the bacterial ribosome, and thus interfering with the mRNA translation process. The miscoding causes membrane damage, which eventuall...
OBJECTIVES The HIV restriction factor, SAMHD1 (SAM domain and HD domain-containing protein 1), is a triphosphohydrolase that degrades deoxyribonucleoside triphosphates (dNTPs). Mutations in SAMHD1 cause Aicardi-Goutières syndrome (AGS), an inflammatory disorder that shares phenotypic similarity with systemic lupus erythematosus, including activation of antiviral type 1 interferon (IFN). To furt...
Background: Post-acrosomal sheath WW domain binding protein (PAWP) is one of sperm factors related to oocyte activation and is expressed in elongating spermatid. Previously, the effect of high of testicular temperature in infertile men with varicocele on semen quality, sperm DNA damage, expression of genes and proteins were reported. In this study, expression of PAWP at RNA and protein levels, ...
Speedy (Spy1) is a novel cell cycle regulator that binds and activates cdk2, and was originally identified as a suppressor of Rad1 deficiency in Schizosaccharomyces pombe. Here we demonstrate that overexpression of human Spy1 enhances mammalian cell viability during cellular responses to DNA damage induced by genotoxic agents such as camptothecin, cisplatin, and hydroxyurea. Clonogenic survival...
Autosomal dominant mutations of the RNA/DNA binding protein FUS are linked to familial amyotrophic lateral sclerosis (FALS); however, it is not clear how FUS mutations cause neurodegeneration. Using transgenic mice expressing a common FALS-associated FUS mutation (FUS-R521C mice), we found that mutant FUS proteins formed a stable complex with WT FUS proteins and interfered with the normal inter...
