Sex dependent glial-specific changes in the chromatin accessibility landscape in late-onset Alzheimer’s disease brains

open access: yesMolecular Neurodegeneration, 2021
Background In the post-GWAS era, there is an unmet need to decode the underpinning genetic etiologies of late-onset Alzheimer’s disease (LOAD) and translate the associations to causation.

Additional sex combs interacts with enhancer of zeste and trithorax and modulates levels of trimethylation on histone H3K4 and H3K27 during transcription of hsp70. [PDF]

open access: yes, 2017
BACKGROUND: Maintenance of cell fate determination requires the Polycomb group for repression; the trithorax group for gene activation; and the enhancer of trithorax and Polycomb (ETP) group for both repression and activation.

Meiotic sex chromosome cohesion and autosomal synapsis are supported by Esco2.

open access: yes, 2020
In mitotic cells, establishment of sister chromatid cohesion requires acetylation of the cohesin subunit SMC3 (acSMC3) by ESCO1 and/or ESCO2. Meiotic cohesin plays additional but poorly understood roles in the formation of chromosome axial elements (AEs)
