External and internal triggers of cell death in yeast [PDF]

, 2016
In recent years, yeast was confirmed as a useful eukaryotic model system to decipher the complex mechanisms and networks occurring in higher eukaryotes, particularly in mammalian cells, in physiological as well in pathological conditions.

AXL Promotes Ischemic Myelin Repair Through Alleviating Myelin Debris Deposition and Lipid Droplets Accumulation

Advanced Science, EarlyView.
Microglial AXL drives white matter repair after stroke by orchestrating the cleanup of myelin debris. Mechanistically, AXL signals through EGR1 to boost Smpd1 transcription, regulating sphingolipid metabolism and preventing lipid droplet toxicity. Restoring the pathway with ASM therapy mitigates damage, positioning AXL as a key node for therapeutic ...

Hypothalamic lipophagy and energetic balance

Aging, 2011
Autophagy is a conserved cellular turnover process that degrades unwanted cytoplasmic material within lysosomes. Through "in bulk" degradation of cytoplasmic proteins and organelles, including lipid droplets, autophagy helps provide an alternative fuel source, in particular, when nutrients are scarce.

Alterations of Lipid Profile in Livers with Impaired Lipophagy

International Journal of Molecular Sciences, 2022
Non-alcoholic fatty liver disease (NAFLD) is characterized by excessive lipid accumulation in the liver. Various mechanisms such as an increased uptake in fatty acids or de novo synthesis contribute to the development of steatosis and progression to more severe stages. Furthermore, it has been shown that impaired lipophagy, the degradation of lipids by

Liver Stiffness Rises Early in MASLD and Drives Inflammation, Lipid Dysmetabolism, and Fibrosis via Piezo1–YAP Mechanotransduction

Advanced Science, EarlyView.
Progressive stiffening of the hepatic extracellular matrix and free fatty acid overload activate the mechanosensor Piezo1 in steatotic hepatocytes, inducing calcium influx and nuclear translocation of Yes‐associated protein. YAP‐dependent nuclear signaling further drives inflammatory and fibrotic gene programs, lipid metabolic reprogramming, and ...

Cellular Identity Crisis: RD3 Loss Fuels Plasticity and Immune Silence in Progressive Neuroblastoma

Advanced Science, EarlyView.
Researchers discovered that therapy‐induced loss of RD3 protein in neuroblastoma triggers a dangerous shift: cancer cells become more stem‐like, invasive, and resistant to treatment while evading immune detection. RD3 loss suppresses antigen presentation and boosts immune checkpoints, creating an immune‐silent environment.

Telemetric control of peripheral lipophagy by hypothalamic autophagy [PDF]

Autophagy, 2016
Autophagy maintains cellular quality control by degrading organelles, and cytosolic proteins and their aggregates in lysosomes. Autophagy also degrades lipid droplets (LD) through a process termed lipophagy. During lipophagy, LD are sequestered within autophagosomes and degraded by lysosomal acid lipases to generate free fatty acids that are β-oxidized

Computer‐Aided Functional Oligosaccharide Screening and the Regulatory Role in Lipid Metabolism

Food Bioengineering, EarlyView.
ABSTRACT This study investigated the lipid‐lowering effects and intervention mechanisms of structurally diverse functional oligosaccharides on non‐alcoholic fatty liver disease (NAFLD). By integrating computational tools such as molecular docking and molecular dynamics simulations (MDS), a comprehensive “in silico‐in vitro‐in vivo” tri‐dimensional ...

Feeding and lipophagy: it takes guts to deliver

The EMBO Journal, 2022
Refeeding after a period of starvation is known to suppress autophagy in the liver. Surprising new work by Seok et al (2022) shows that refeeding activates lipophagy in the intestine, which may help fats in our diet to be efficiently processed after a meal.
