Atgl-dependent adipocyte lipolysis promotes lipodystrophy and restrains fibrogenic responses during skin fibrosis.

During skin fibrosis, extracellular matrix (ECM) proteins are overproduced, and resident lipid-filled, mature dermal adipocytes are depleted in both human disease and mouse models. However, the mechanisms by which the reduction in lipid-filled adipocytes occurs during fibrosis are not well understood. Here, we identify that adipocyte lipolysis via the rate limiting enzyme, adipocyte triglyceride lipase (Atgl), is required for loss of adipose tissue during skin fibrosis in mice.

The purpose of this study was to investigate the ability of mechanotherapy to enhance recovery or prevent loss of muscle size with atrophy, in female rats. Female F344/BN rats were assigned to weight bearing (WB), hindlimb suspended (HS) for 14 days with reambulation for 7 days without (RA) or with (RAM) mechanotherapy (study 1), or to WB, HS for 7 days, with (HSM) or without mechanotherapy (study 2) to gastrocnemius. Muscle fiber cross sectional area (CSA) and type, collagen, satellite cell number, and protein synthesis (K) and degradation (K) were assessed.

Preeclampsia, a life-threatening pregnancy complication, remains a major global health concern. Understanding the complex molecular mechanisms underlying this disorder is crucial for improving both diagnostics and therapeutic strategies. In this study, a multi-omics approach based on NMR metabolomics and RNA-seq transcriptomics analyses was conducted to analyze placental tissue samples obtained from patients with preeclampsia and healthy controls.

In humans, the 2-oxoglutarate-dependent dioxygenases (2-OGDDs) catalyze hydroxylation reactions involved in cell metabolism, the biosynthesis of small molecules, DNA and RNA demethylation, the hypoxic response and the formation of collagen. The reaction is catalyzed by a highly oxidizing ferryl-oxo species produced when the active site non-heme iron engages molecular oxygen. Enzyme activity is specifically stimulated by l-ascorbic acid (ascorbate, vitamin C), an effect not well mimicked by other reducing agents.

Article Synopsis
- This study investigates the biological changes in rabbit corneas caused by two light-activated corneal stiffening methods: riboflavin with UVA and WST11 with NIR.
- Differentially expressed proteins were identified following treatments, showing RF-D/UVA affected cell metabolism and keratocyte differentiation, while WST-D/NIR influenced extracellular matrix regulation.
- The findings reveal a metabolic shift towards glycolysis in RF-D/UVA treated corneas compared to normal respiration in WST-D/NIR treated corneas, highlighting the distinct biological effects of each treatment.
