Brain Regulation of Energy Metabolism [PDF]

open access: yesEndocrinology and Metabolism, 2016
In healthy individuals, energy intake is in balance with energy expenditure, which helps to maintain a normal body weight. The brain's inability to control energy homeostasis underlies the pathology of hyperphagia and obesity.

Blood Levels of Neuropeptide 26RFa in Relation to Anxiety and Aggressive Behavior in Humans—An Exploratory Study

open access: yesBrain Sciences, 2023
26RFa, also referred to as QRFP, is a hypothalamic neuropeptide mainly known for its role in the regulation of appetite and glucose metabolism. Its possible relevance to emotional regulation is largely unexplored.

Impact of the gut microbiota on inflammation, obesity, and metabolic disease [PDF]

open access: yes, 2016
The human gut harbors more than 100 trillion microbial cells, which have an essential role in human metabolic regulation via their symbiotic interactions with the host.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Current status of traditional Chinese medicine in modulating mitochondrial metabolic abnormalities in tumors

open access: yesCancer Biology & Medicine
Tumor cells undergo metabolic reprogramming to adapt to rapid proliferation and harsh microenvironments, as evidenced by aerobic glycolysis. Mitochondria serve as key coordinators of this process.

Bioactivity in Whey Proteins Influencing Energy Balance [PDF]

open access: yes, 2012
Peer-reviewedObesity develops due to energy (food) intake exceeding energy expenditure. Nutrients that reduce the positive energy balance are thus being considered as therapies to combat obesity.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

PI3K/AKT/mTOR pathway and c-Myc inhibit hepatocyte suspension under simulated microgravity

open access: yesnpj Microgravity
Microgravity affects cell growth and apoptosis. Using a random positioning machine, we previously found that simulated microgravity (SMG) suppresses total cell proliferation and induces apoptosis of in vitro cultured hepatocytes.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Partial involvement of Nrf2 in skeletal muscle mitohormesis as an adaptive response to mitochondrial uncoupling

open access: yesScientific Reports, 2018
Mitochondrial dysfunction is usually associated with various metabolic disorders and ageing. However, salutary effects in response to mild mitochondrial perturbations have been reported in multiple organisms, whereas molecular regulators of cell ...
