FEBS 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.

Evidence linking exposure of fish primary macrophages to antibiotics activates the NF-kB pathway. [PDF]
, 2020 Low doses of antibiotics are ubiquitous in the marine environment and may exert negative effects on non-target aquatic organisms. Using primary macrophages of common carp, we investigated the mechanisms of action following exposure to several common ...

Structural biology of ferritin nanocages
FEBS 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 ...

Notch-1 signaling promotes the malignant features of human breast cancer through NF-κB activation.
PLoS ONE, 2014 The aberrant activation of Notch-1 signaling pathway has been proven to be associated with the development and progression of cancers. However, the specific roles and the underlying mechanisms of Notch-1 signaling pathway on the malignant behaviors of ...

The Role of RASSF5 on Cell Growth and Hippo Signaling in Rhabdomyosarcoma [PDF]
, 2020 Introduction: Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma of childhood. Dysregulation of the Hippo pathway, a signaling cascade that regulates many biological processes, is associated with many human cancers.

Neurotrophin-regulated signalling pathways [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2006 Neurotrophins are a family of closely related proteins that were identified initially as survival factors for sensory and sympathetic neurons, and have since been shown to control many aspects of survival, development and function of neurons in both the peripheral and the central nervous systems.

FEBS 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 ...

Magnolol alleviates inflammation and oxidative stress in COPD via MAPK and Nrf2 signaling pathways
Current Research in BiotechnologyChronic obstructive pulmonary disease (COPD) is a chronic and progressive lung disease which is closely related to inflammation and oxidative-stress. Magnolol (MAG) is a polyphenolic compound that possesses extensive pharmacological actions, including ...

The Nrf2-Antioxidant Response Element Signaling Pathway and Its Activation by Oxidative Stress*
Journal of Biological Chemistry, 2009 A major mechanism in the cellular defense against oxidative or electrophilic stress is activation of the Nrf2-antioxidant response element signaling pathway, which controls the expression of genes whose protein products are involved in the detoxication ...
