Background: Understanding the fundamental differences between the human and pre-human brain is a prerequisite for designing meaningful models and therapies for AD. Expressed CHRFAM7A, a human restricted gene with carrier frequency of 75% in the human population predicts profound translational significance.
Method: The physiological role of CHRFAM7A in human brain is explored using multiomics approach on 600 post mortem human brain tissue samples (ROSMAP).

In prokaryotes, DNA methylation plays roles in DNA repair, gene expression, cell cycle progression, and immune recognition of foreign DNA. Genome-wide methylation patterns can vary between strains, influencing phenotype, and gene transfer. However, broader evolutionary studies on bacterial epigenomic variation remain limited.

Background: Fusarium head blight (FHB) is a major disease affecting cereal crops including wheat, barley, rye, oats and maize. Its predominant causal agent is the ascomycete fungus Fusarium graminearum, which infects the spikes and thereby reduces grain yield and quality. The frequency and severity of FHB epidemics has increased in recent years, threatening global food security.

Background: Considerable heterogeneity in genotypes and phenotypes has been observed among patients with amyotrophic lateral sclerosis (ALS) harbouring optineurin gene () mutations, as reported in prior studies. The study aimed to elucidate the correlation between genotypes and phenotypes.
Methods: gene variants were screened within a substantial Chinese cohort of patients with ALS, encompassing LoF and rare missense variants.

Background: Although epigenomic and environment interactions (Epigenome × Environment; Epi × E) might constitute a novel mechanism underlying reward processing direct evidence is still scarce. We conducted the first longitudinal study to investigate the extent to which DNA methylation of a stress-related gene-NR3C1-interacts with childhood maltreatment in association with young adult reward responsiveness (RR) and the downstream risk of depressive (anhedonia dimension in particular) and anxiety symptoms.
Method: A total of 192 Chinese university students aged 18∼25 (M = 21.
