Pseudogenization of rcsD alters canonical Rcs phosphorelay signalling and marks a significant adaptive evolutionary step in the emergence of ubiquitous extant branches of Yersinia pestis that can maintain stable plague outbreaks.
The nutrient-sensing GCN2 signaling pathway is required for robust circadian rhythm by recruiting the histone acetyltransferase GCN5 to establish a proper chromatin state at the circadian clock gene promoter under amino acid starvation in Neurospora.
Natural temperature variation across an optimal reproductive range for wild flies (Drosophila melanogaster) modulates the impact of sexual conflict on female fitness via asymmetric effects on pre- and post-copulatory male harm mechanisms.
Down-regulation of GAS6 by M1 macrophages resulted in impaired efferocytosis for synovial apoptotic cells, causing synovial hyperplasia and obesity-associated OA development.
There are fourteen genomic variants of Mycobacterium tuberculosis that are significantly associated with poor treatment outcomes in drug-susceptible TB patients, but their predictive value is limited.
The ovarian immune system ages while coping with the two main challenges of the aging ovary before menopause, the inflammatory stimulations due to repeated cycles and the increasing need for clearance of accumulating atretic follicles.
