RNA editing is a significant mechanism underlying genetic variation and protein molecule alteration; C-to-U RNA editing, specifically, is important in the regulation of mammalian genetic diversity. The ability to define and limit accesses of enzymatic machinery to avoid the modification of unintended targets is key to the success of RNA editing. Identification of the core component of the apoB RNA editing holoenzyme, APOBEC, and investigation into new candidate genes encoding other elements of the complex could reveal further details regarding APOBEC-mediated mRNA editing.

Neurodegenerative diseases are characterized by profound differences between females and males in terms of incidence, clinical presentation, and disease progression. Furthermore, there is evidence suggesting that differences in sensitivity to medical treatments may exist between the two sexes. Although the role of sex hormones and sex chromosomes in driving differential susceptibility to these diseases is well-established, the molecular alterations underlying these differences remain poorly understood.

Background: Vascular cognitive impairment (VCI) is a significant contributor to dementia, yet the precise mechanisms underlying the cognitive decline associated with chronic cerebral hypoperfusion (CCH) remain unclear. This study investigated the molecular and epigenetic changes in the striatum, a brain region critical for motor function and cognition, following chronic hypoperfusion using a bilateral common carotid artery stenosis (BCAS) model in mice.
Methods: RNA-seq was utilized to identify differentially expressed genes (DEGs) associated with hypoperfusion.

The number and variety of identified histone post-translational modifications (PTMs) are continually increasing. However, the specific consequences of each histone PTM remain largely unclear, primarily due to the lack of methods for selectively and rapidly introducing a desired histone PTM in living cells without genetic engineering. Here, we report the development of a cell-permeable histone acetylation catalyst, BAHA-LANA-PEG-CPP44, which selectively enters leukemia cells, binds to chromatin, and acetylates H2BK120 of endogenous histones in a short reaction time.
