DNA methylation mechanisms in the maturing and ageing oocyte

Epigenetics & Chromatin
Oocyte maturation involves both nuclear and cytoplasmic processes that are critical for the acquisition of oocyte competence. Granulosa cells, surrounding the oocyte, play a pivotal role in the maturation process, with mechanisms such as cAMP signaling ...

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Escaping Constraints to Innovate: Maternal Neofunctionalization in a HoxB4 Duplicate

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Whole‐genome duplication in Xenopus laevis generated duplicated Hox genes that are largely constrained in sequence and developmental expression. However, HoxB4L uniquely acquired maternal expression through cis‐regulatory and protein structural divergence, illustrating how gene duplication enables transcription factors to escape pleiotropic constraints

Alogliptin Reduces Oxidative Stress in Cardiomyocytes and Ameliorates Diabetic Cardiomyopathy via the AURKB/NLGN2 Signaling

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Diabetic cardiomyopathy (DCM) is a common complication of diabetes mellitus. This study investigated the effects of alogliptin on DCM and its underlying mechanisms. A DCM model was constructed and treated with alogliptin. Downstream targets of alogliptin were screened using bioinformatics analysis.
