UNC45B Reduction With Aging: A Myofiber‐Intrinsic Promoting Factor for Sarcopenia

Aging Cell, Volume 25, Issue 5, May 2026.
Aging reduces Unc45b expression in fast‐twitch muscle, concomitant with reduction in muscle contractile capacity and muscle mass in mice. Unc45b deficiency initially reduces depolarization‐induced force, followed by a decline in fast‐twitch muscle mass in adult mice.

Extracellular RNA as a molecular driver and therapeutic target in abdominal aortic aneurysms

Scientific Reports
Abdominal aortic aneurysms (AAAs) are characterized by chronic inflammation, matrix degradation and smooth muscle cell (SMC) loss, leading to vessel dilation and rupture, with no current pharmaceutical management options.

Overexpressing the ClpC AAA+ unfoldase accelerates developmental cycle progression in Chlamydia trachomatis

mBio
Chlamydia is an obligate intracellular bacterium that undergoes a complex biphasic developmental cycle, alternating between the smaller, infectious, non-dividing elementary body (EB) and the larger, non-infectious but dividing reticulate body. Due to the

Stress Granule‐Associated ZmCTU2 Confers Thermotolerance in Maize via Coordinated Regulation of Proteostasis and ROS Homeostasis

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3371-3390, May 2026.
ABSTRACT The escalating global temperatures and intensifying heat stress events pose significant threats to maize productivity worldwide. Uncovering key thermotolerance genes and their functional mechanisms is thus critical for developing climate‐resilient crops.

Fully Tunable Phosphorylation of RPS6A Ensures the Successful Development of Arabidopsis Seedlings

Plant, Cell &Environment, Volume 49, Issue 5, Page 2783-2794, May 2026.
ABSTRACT Light enhances protein translation, enabling young seedlings to rapidly and timely acquire photosynthetic capacities. Sequential phosphorylation of ribosomal protein S6 (RPS6) was implicated in the light‐enhanced translation; however, the exact phosphorylation sites and the biological relevance of RPS6 multi‐phosphorylation in seedling ...

Molecular Mechanisms of Secreting Vesicle Biogenesis and Secretion in Chronic Degenerative Diseases [PDF]

, 2012
Regulated trafficking and secretion of insulin by the β cell of the endocrine pancreas is critical to maintain our body energy homeostasis. Disruption of these processes typically leads to hyperglycemia and the complications of diabetes.

Dual-topology insertion of a dual-topology membrane protein. [PDF]

, 2015
Some membrane transporters are dual-topology dimers in which the subunits have inverted transmembrane topology. How a cell manages to generate equal populations of two opposite topologies from the same polypeptide chain remains unclear.

Membrane topology of the ArsB protein, the membrane subunit of an anion-translocating ATPase [PDF]

, 1992
The ars operon of the conjugative R-factor R773 encodes an oxyanion pump that catalyzes extrusion of arsenicals from cells of Escherichia coli. The oxyanion translocation ATPase is composed of two polypeptides, the catalytic ArsA protein and the ...

Functional analysis of mammalian m-AAA proteases

, 2008
The m-AAA protease, an ATP-dependent proteolytic complex in the inner mitochondrial membrane, controls mitochondrial protein quality and, acting as a processing enzyme, regulates mitochondrial protein synthesis in yeast. Mammalian m-AAA proteases assemble into several isoenzymes with variable subunit composition.
