Branched-chain amino acids catabolism and cancer progression: focus on therapeutic interventions

open access: yesFrontiers in Oncology, 2023
Branched-chain amino acids (BCAAs), including valine, leucine, and isoleucine, are crucial amino acids with significant implications in tumorigenesis across various human malignancies.

Inhibition of HMGB1 suppresses inflammation and catabolism in temporomandibular joint osteoarthritis via NF-κB signaling pathway

open access: yesEuropean Journal of Histochemistry, 2022
HMGB1 is a highly conserved nuclear protein that is rapidly released into the extracellular environment during infection or tissue damage. In osteoarthritis, HMGB1 acts as a pro-inflammatory cytokine inducing a positive feedback loop for synovial ...

Ferroptosis Inhibition by Lysosome-Dependent Catabolism of Extracellular Protein

open access: yesCell Chemical Biology, 2022
SUMMARY Cancer cells must ensure a steady supply of nutrients to enable proliferation and evade cell death. Depriving cancer cells of the amino acid cystine can trigger the non-apoptotic cell death process of ferroptosis.

Cryo‐EM structure of fission yeast tetrameric α‐mannosidase Ams1

open access: yesFEBS Open Bio, 2020
Fungal α‐mannosidase Ams1 and its mammalian homolog MAN2C1 hydrolyze terminal α‐linked mannoses in free oligosaccharides released from misfolded glycoproteins or lipid‐linked oligosaccharide donors.

Amino acid catabolism regulates hematopoietic stem cell proteostasis via a GCN2-eIF2α axis.

open access: yesCell Stem Cell, 2022
Hematopoietic stem cells (HSCs) adapt their metabolism to maintenance and proliferation; however, the mechanism remains incompletely understood. Here, we demonstrated that homeostatic HSCs exhibited high amino acid (AA) catabolism to reduce cellular AA ...

Cancer Cachexia Induces Preferential Skeletal Muscle Myosin Loss When Combined With Denervation

open access: yesFrontiers in Physiology, 2020
Patients with cancer cachexia (CCX) suffer from muscle wasting, which is often but not always accompanied by selective loss of myosin. Here we examined the effects of CCX on muscle mass and myosin heavy chain (MyHC) expression in denervated (DEN) muscles,

Unraveling the 17β-Estradiol Degradation Pathway in Novosphingobium tardaugens NBRC 16725

open access: yesFrontiers in Microbiology, 2020
We have analyzed the catabolism of estrogens in Novosphingobium tardaugens NBRC 16725, which is able to use endocrine disruptors such as 17β-estradiol, estrone, and estriol as sole carbon and energy sources.

Role of Parathyroid Hormone and Parathyroid Hormone-Related Protein in Protein-Energy Malnutrition

open access: yesFrontiers in Bioscience-Landmark, 2023
Parathyroid hormone (PTH) is an endocrine peptide found exclusively in the parathyroid glands, whereas parathyroid hormone-related protein (PTHrP) is expressed in a wide range of tissues and organs and exerts endocrine, paracrine, and autocrine actions ...

Use of Digital Technologies in the Nutritional Management of Catabolism-Prone Chronic Diseases: A Rapid Review

open access: yes, 2021
**Background:** Diet and nutrition applications (apps) have become more readily accessible as smartphone ownership increases. These apps have the potential to improve nutritional outcomes, but it remains unclear whether they are effective in patients ...
