Mind the Porins: Differential Effects of Porin Knockouts and Overexpression on Glucose and Xylose Uptake and Utilization in Pseudomonas putida

Microbial Biotechnology, Volume 19, Issue 7, July 2026.
Altering the levels of outer membrane (OM) porins has an effect on the dynamics of the utilization and co‐utilization of native (glucose—green hexagon) and non‐native (xylose—brown pentagon) sugars, as well as the accumulation of their oxidation byproducts in Pseudomonas putida cultures.

MomL, a novel marine-derived N-acyl homoserine lactonase from Muricauda olearia

, 2015
Gram-negative bacteria use N-acyl homoserine lactones (AHLs) as quorum sensing (QS) signaling molecules for interspecies communication, and AHL-dependent QS is related with virulence factor production in many bacterial pathogens.

RAGE Re‐Expressed at Myofibre Level Drives Muscle Wasting in Cancer Conditions

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 3, June 2026.
ABSTRACT Background Cancer cachexia (CC) is a highly debilitating syndrome characterized by loss of body and muscle weight affecting most advanced cancer patients. The receptor for advanced glycation end‐products (RAGE) is expressed by several cell types and sustains the inflammatory response in acute and chronic diseases. Total ablation of RAGE (Ager−/
