Structural States of Hdm2 and HdmX: X-ray Elucidation of Adaptations and Binding Interactions for Different Chemical Compound Classes

448 views | Jun 26 2019

Kallen J et al. used the same numbering for Hdm2 (as in Q00987) and HdmX (as in O15151, but minus 1). Taken together, these structural insights should prove useful for the design and optimization of further selective and/or dual Hdm2/HdmX inhibitors. [Read the Full Post]

Age-related macular degeneration (AMD) mitochondria modulate epigenetic mechanisms in retinal pigment epithelial cells

928 views | Jun 23 2019

Nashine S et al. revealed that AMD mitochondria regulate epigenetic mechanisms i.e., methylation and acetylation status. Demethylation using 5-Aza-2'-deoxycytidine (DAC) caused differential expression of VEGF-A gene in AMD cells. Trichostatin A (TSA), an HDAC inhibitor, also influenced protein levels of VEGF-A, HIF1α, NFκB, and CFH in AMD cells. This study might advance the field of AMD research since in addition to highlighting the critical role of nuclear-mitochondrial interactions that influence epigenetic mechanisms in AMD patients, this work suggests epigenetic profiles as potential therapeutic targets for AMD.

Puromycin reaction for the A site-bound peptidyl-tRNA

538 views | Jun 16 2019

Semenkov Yu et al. indicated that the transpeptidation reaction per se triggers conformational changes in the ribosomal complex bringing the 3'-end of a newly synthesized peptidyl-tRNA nearer to the peptidyl-site of the peptidyltransferase center. This is detected functionally as the ability of such an A site bound peptidyl-tRNA to react with puromycin. This reaction is highly pronounced at elevated (25 degrees C) temperature but can be hardly detected at 0 degrees C. [Read the Full Post]
