The roles of mitochondrial glutaredoxin (Grx2a) under serum deprivation were assessed using the human stable HepG2 cell lines overexpressing or down-regulating Grx2a. The Grx2a-overexpressing stable cells displayed enhanced proliferation, decreased reactive oxygen species (ROS) and caspase-3 activity levels, and increased total GSH level, compared to the(More)
Ginsenoside Rg3 is one of ginsenosides that are the well-known bioactive principles of Panax ginseng. Among the two stereoisomeric forms of Rg3, 20(S)-ginsenoside Rg3 [20(S)-Rg3] is predominant. 20(S)-Rg3 is capable of suppressing the nitric oxide (NO), reactive oxygen species (ROS) and prostaglandin E2 (PGE2) productions induced by lipopolysaccharide (LPS)(More)
We examined whether steady-state mRNA levels of five tumor suppressor genes are subjected to oxidative stress. Superoxide radical-generating menadione and serum deprivation diminished the steady-state mRNA levels for the genes phosphatase and tensin homolog (PTEN), ubiquitin specific peptidase 28 (USP28), damage-regulated autophagy modulator (DRAM),(More)
BACKGROUND Multiple neurodegenerative diseases are characterized by the abnormal accumulation of FUS protein including various subtypes of frontotemporal lobar degeneration with FUS inclusions (FTLD-FUS). These subtypes include atypical frontotemporal lobar degeneration with ubiquitin-positive inclusions (aFTLD-U), basophilic inclusion body disease (BIBD)(More)
The present work aimed to examine whether transcriptional regulation of the human PGC-1α gene encoding peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) is subjected to oxidative stress or not. Oxidative stressors, such as superoxide radical-generating menadione (MD) and hydrogen peroxide (H2O2), brought about a diminishment in the PGC-1α(More)
AIM To treat neurodegenerative disorders such as Parkinson's disease (PD), drugs must be able to cross the blood-brain barrier (BBB). Patients with PD are deficient in dopamine (DA), a neurotransmitter that cannot pass through the BBB. Liposomes modified by adding polyethylene glycol (PEGylated liposomes (PLs)) can be conjugated with antibody to form(More)
This work aimed to assess some pharmacological activities of P. leptostachya var. asiatica Hara. The dried roots of P. leptostachya var. asiatica Hara were extracted with 70% ethanol to generate the powdered extract, named PLE. Anti-angiogenic activity was detected using chick chorioallantoic membrane (CAM) assay. In vitro anti-inflammatory activity was(More)
