Interplay between Skeletal Muscle Catabolism and Remodeling of Arteriovenous Fistula via YAP1 Signaling.
J Am Soc Nephrol
January 2025
Selzman Institute for Kidney Health, Section of Nephrology, Department of Medicine, Baylor College of Medicine, Houston, Texas 77030.
Background: Arteriovenous (AV) fistulas are the preferred access for dialysis but have a high incidence of failure. This study aims to understand the crosstalk between skeletal muscle catabolism and AV fistula maturation failure.
Methods: Skeletal muscle metabolism and AV fistula maturation were evaluated in mice with chronic kidney disease (CKD).
Exploring melatonin's signalling pathways in the protection against age-related skin deterioration.

Melatonin, renowned for regulating sleep-wake cycles, also exhibits notable anti-aging properties for the skin. Synthesized in the pineal gland and various tissues including the skin, melatonin's efficacy arises from its capacity to combat oxidative stress and shield the skin from ultraviolet (UV)-induced damage. Moreover, it curbs melanin production, thereby potentially ameliorating hyperpigmentation.

Background: Pseudomonas aeruginosa's inherent and adapted resistance makes this pathogen a serious problem for antimicrobial treatments. Furthermore, its biofilm formation ability is the most critical armor against antimicrobial therapy, and the virulence factors, on the other hand, contribute to fatal infection and other recalcitrant phenotypic characteristics. These capabilities are harmonized through cell-cell communication called Quorum Sensing (QS), which results in gene expression regulation via three major interconnected circuits: las, rhl, and pqs system.

Optimizing central carbon metabolism (CCM) represents an attractive and challenging strategy to improve the biosynthesis of valuable chemicals due to the complex regulation of the CCM in yeast. In this study, we triggered the similar Warburg effect of cancer cells in yeast strains by introducing the human hypoxia-inducible factor-1 (HIF-1) complex, which regulated the expression of numerous enzymes involved in CCM and redirected the metabolic flux from glycolysis to tricarboxylic acid cycle. This redirection promoted the production of squalene to a 2.

CSIR-Central Institute of Medicinal and Aromatic Plants, P.O. CIMAP, Lucknow, 226015, Uttar Pradesh, India.
Foliar-applied Zn on Catharanthus roseus enhanced production of vindoline, the main impediment precursor for costly anticancer bisindoles. A leaf-abundant CrZIP was characterized for likely role in modulating vindoline metabolism. The leaf-localized Catharanthus roseus alkaloid, vindoline, is the major impediment precursor in the production of scanty and expensive anticancer bisindoles, vinblastine and vincristine.
