An improved superoxide-generating nanodevice for oxidative stress studies in cultured cells

Biotechnology Reports, 2015
The effects of reactive oxygen species on cells have attracted great attention from both physiological and pathological aspects. Superoxide (O2−) is the primary reactive oxygen species formed in animals.

Blood cytokine patterns suggest a modest inflammation phenotype in subjects with long‐chain fatty acid oxidation disorders

Physiological Reports, 2019
Excessive cellular accumulation or exposure to lipids such as long‐chain acylcarnitines (LCACs), ceramides, and others is implicated in cell stress and inflammation.

Caspase-3 deficiency during development increases vulnerability to hypoxic–ischemic injury through caspase-3-independent pathways

Neurobiology of Disease, 2006
Neonatal hypoxia–ischemia (H–I) is a common cause of perinatal morbidity and mortality leading to prominent activation of caspase-3 in the brain. Previous studies have shown that acute inhibition of caspase-3 can protect against neonatal H–I in rats.

Total extract of Abelmoschus manihot L. alleviates uric acid-induced renal tubular epithelial injury via inhibition of caspase-8/caspase-3/NLRP3/GSDME signaling

Frontiers in Pharmacology, 2022
Purpose: The incidence of uric acid (UA)-induced kidney injury is increasing owing to the high incidence of hyperuricemia in recent years. The flower of Abelmoschus manihot (Linneus) Medik is a traditional Chinese medicinal herb widely used in the ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Apoptosis in prostate carcinoma tissue: The role of caspase-3, caspase-1, and alkaline DNase activity [PDF]

Journal of Medical Biochemistry
Background: Prostate glandular tissue maintains a delicate balance between cellular proliferation and programmed cell death (apoptosis), ensuring the preservation of normal glandular architecture in healthy individuals.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Caspase inhibition attenuates accumulation of β-amyloid by reducing β-secretase production and activity in rat brains after stroke

Neurobiology of Disease, 2008
In this study, we tested if caspase-3 inhibition decreased ischemia-induced Aβ elevation by reducing β-secretase (BACE1) activity. Changes in caspase-3, Aβ and BACE1 levels were detected in rat striatum on different days after middle cerebral artery ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
