SARS‐CoV‐2 nucleocapsid protein variants have differential RNA chaperone activity

The FEBS Journal, EarlyView.
The SARS‐CoV‐2 nucleocapsid (N) protein facilitates RNA annealing through its RBD–IDR2–CTD region, identifying it as a functional RNA chaperone. The Omicron BA.5 variant shows reduced chaperone activity compared to the Wuhan wild‐type protein. Although phosphorylation has no effect on wild‐type N, phosphomimetic modification of BA.5 N restores its RNA ...

Oxygen‐independent expression of HIF‐1α during the cell cycle in hepatocellular carcinoma cells controls essential metabolic pathways under normoxia

The FEBS Journal, EarlyView.
In Huh7 cells, HIF‐1α is essential as it maintains the expression of proteins involved in glycolysis and steroid/cholesterol biosynthesis both under normoxia and hypoxia. On the other hand, in HeLa cells, these pathways are induced by HIF‐1α only under hypoxia.

Developmental expression of Ap‐Vas proteins in aphids and flies reveals their evolutionary roles in insects

Insect Molecular Biology, EarlyView.
Duplication of vas genes is universally observed in aphids, and phylogenetic analysis indicates that this event predates the divergence of Aphididae and Phylloxeridae. Ap‐vas1 is germline‐specific, whereas Ap‐vas2–4 exhibit somatic expression, indicating functional divergence during aphid embryogenesis.

Innate Immune Activation Is a Strong Suppressor of CCL22 and Impedes Regulatory T Cell–Dendritic Cell Interaction

Immunology, EarlyView.
During homeostasis, CCL22 is secreted by dendritic cells (DC), which mediate contacts between regulatory T cells (Treg) and DC to maintain immune balance. Activation of innate immunity via microbes or pattern recognition receptor (PRR) agonists induces the secretion of several soluble factors (e.g., type I and II interferons, IL‐10), which mediate ...

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...
