Calcium bridges built by mitochondria-associated endoplasmic reticulum membranes: potential targets for neural repair in neurological diseases

Neural Regeneration Research
The exchange of information and materials between organelles plays a crucial role in regulating cellular physiological functions and metabolic levels. Mitochondria-associated endoplasmic reticulum membranes serve as physical contact channels between the ...

Endoplasmic Reticulum Stress and Unfolded Protein Response in Breast Cancer: The Balance between Apoptosis and Autophagy and Its Role in Drug Resistance

International Journal of Molecular Sciences, 2019
The unfolded protein response (UPR) is a stress response activated by the accumulation of unfolded or misfolded proteins in the lumen of the endoplasmic reticulum (ER) and its uncontrolled activation is mechanistically responsible for several human ...

The selectivity and specificity of autophagy in drosophila [PDF]

, 2012
Autophagy is a process of cellular self-degradation and is a major pathway for elimination of cytoplasmic material by the lysosomes. Autophagy is responsible for the degradation of damaged organelles and protein aggregates and therefore plays a ...

MicroRNA‐375‐3p Targets Fatty Acid Synthase and Relish to Regulate Energy Allocation During Pupal Metamorphosis and Starvation

Advanced Science, EarlyView.
During pupal metamorphosis and starvation, elevated 20‐hydroxyecdysone (20E) and suppressed insulin trigger Forkhead box O (FOXO) nuclear translocation, enhancing miR‐375‐3p expression. This downregulates fatty acid synthase (FASN) and Relish, promoting lipid breakdown for energy while prioritizing antioxidant responses over immune functions to support

Endoplasmic reticulum stress and autophagy in cerebral ischemia/reperfusion injury: PERK as a potential target for intervention

Neural Regeneration Research
Several studies have shown that activation of unfolded protein response and endoplasmic reticulum (ER) stress plays a crucial role in severe cerebral ischemia/reperfusion injury. Autophagy occurs within hours after cerebral ischemia, but the relationship

Regulation of the homeostasis of hepatic endoplasmic reticulum and cytochrome P450 enzymes by autophagy

Liver Research, 2018
The endoplasmic reticulum (ER) is an intracellular organelle consisting of a continuous network of membranes. In the liver, the ER is highly active in protein modification, lipid metabolism, and xenobiotic detoxification.

Transcriptional Response to Acute Thermal Exposure in Juvenile Chinook Salmon Determined by RNAseq. [PDF]

, 2015
Thermal exposure is a serious and growing challenge facing fish species worldwide. Chinook salmon (Oncorhynchus tshawytscha) living in the southern portion of their native range are particularly likely to encounter warmer water due to a confluence of ...

Macrophage autophagy in atherosclerosis [PDF]

, 2013
Macrophages play crucial roles in atherosclerotic immune responses. Recent investigation into macrophage autophagy (AP) in atherosclerosis has demonstrated a novel pathway through which these cells contribute to vascular inflammation.

Engineered GM1 Intersects Between Mitochondrial and Synaptic Pathways to Ameliorate ALS Pathology

Advanced Science, EarlyView.
Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease driven by genetic and molecular disruptions affecting energy balance, protein homeostasis, and stress responses in nerve cells. Studies using human and rodent models identified convergent defects in mitochondria and synaptic function.

Ufmylation‐Deficient DDRGK1 Ameliorates Obesity by Inhibiting FASN‐Mediated Adipocyte Lipogenesis

Advanced Science, EarlyView.
DDRGK1 regulates de novo lipogenesis via stabilization of fatty acid synthase (FASN). DDRGK1‐mediated UFMylation of FASN prevents its ubiquitin–proteasomal degradation. Reduced DDRGK1 expression or mutation at the key UFMylation site enhances FASN degradation and suppresses fatty acid synthesis (FAS), resulting in smaller adipocytes and improved ...
