Hypoxia-inducible factor (HIF)-1α is consistently and dramatically upregulated in a variety of fibrotic diseases. The aim of this study was to compare HIF-1α expression from fibroblasts derived from human normal buccal mucosa and oral submucous fibrosis (OSF) specimens and further to explore the
A 25 min anoxia, or an intracerebroventricular bilateral 2 nmol dose of ethylcholine aziridinium (AF-64A), administered postnatally to male rat pups, elicited on further development of these behavioural disorders, which are partly related to central cholinergic hypofunction. These included a
The role of hypothermia in the antihypoxic effects of drugs was examined in the present experiments. The effects of environmentally induced hypothermia and drugs were tested by exposing mice to 100% nitrogen gas for 80 sec and counting the number of survivors. In a series of 68 vehicle control
BACKGROUND
Oral submucous fibrosis (OSF) is regarded as a pre-cancerous condition with fibrosis in oral subepithelial connective tissue. Hypoxia-inducible factor (HIF)-1α regulates a wide variety of profibrogenic genes, which are closely associated with tissue fibrosis. The aim of this study was to
OBJECTIVE
Hypoxia inducible factor (HIF)-1α gene expression is mainly induced by tissue hypoxia. Overexpression of HIF-1α has been demonstrated in a variety of cancers. The aim of this study was to compare HIF-1α expression in normal human oral epithelium and areca quid chewing-associated oral
Long non-coding RNA hypoxia-inducible factor 1α-antisense RNA 1 (HIF1A-AS1) has been known to participate in various types of malignancies, but its role in the development of precancerous oral submucous fibrosis (OSF) has not been investigated. In the current study, we first observed the aberrant
Arecoline is one of the main medicinal constituents in areca. Melatonin is an amine molecule with multiple functions in plants and animals. However, the interaction between arecoline and melatonin remains unknown. Herein, metabolomics analysis showed that multiple metabolites including arecoline
Cytochrome C (a single dose range of 1-200 mg/kg, intraperitoneally) does not possess the antihypoxic activity (altitude chamber, methemoglobinemia, circulatory hypoxia), decreases (in a dose of 50 mg/kg) diuresis in rats modifying diversely (depending on the dose used) the hypnotic effects of
To test the hypothesis that decreased acetylcholine (ACh) metabolism during hypoxia is behaviorally important, the effects of cholinergic drugs and 4-aminopyridine, an enhancer of ACh release, were examined in hypoxic mice. Chemical hypoxia (150 mg/kg NaNO2) reduced tight rope test scores from 13.2
Oral submucous fibrosis (OSF) is prevalent mostly in Southeast Asia, particularly in the Indian subcontinent. Chewing betel nuts and betel leaves, with or without tobacco, has been associated with OSF. Betel quid contents including guvacine, arecoline, guvacoline, arecaidine, and chavibetol are
