OBJECTIVES/HYPOTHESIS Age-related hearing loss has a genetic component, but there have been limited genetic studies in this field. Both N-acetyltransferase 2 and apolipoprotein E genes have previously been associated. However, these studies have either used small sample sizes, examined a limited number of polymorphisms, or have produced conflicting results. Here we use a haplotype tagging appro...

Choline acetyltransferase activity, which is rate limiting in acetylcholine biosynthesis, was measured in the four heart chambers of guinea pigs subjected to (1) sham surgery, (2) constriction of the ascending aorta, (3) constriction of the descending thoracic aorta, and (4) constriction of the pulmonary artery. After 30 days when hypertrophy and heart failure were fully established, choline ac...

Abstract N-acetyltransferase 10 catalyzes RNA N4-acetylcytidine (ac4C) modifications and thus regulates stability translation efficiency. However, the deacetylase for ac4C is unknown. SIRT7 was initially identified as an NAD + -dependent protein plays essential roles in genome stability, circadian rhythms, metabolism, aging. In this study, we a of ribosomal (r)RNA first time found it to be -ind...

The aim of this study was to determine the association of n-acetyltransferase-2 polymorphisms and anti-tuberculosis drug-induced hepatotoxicity in Iranian pulmonary tuberculosis patients. Acetylating phenotypes was studied in 50 Iranian pulmonary tuberculosis patients using metabolic ratio of plasma acetyl-Isoniazid to Isoniazid. The association between hepatotoxicity and the n-acetyltransferas...
