Nicotine, the principal alkaloid in tobacco, induces a cellular damage on heart and cardiomyocyte culture. We investigate the protective role of green tea extract (GTE) against nicotine. Male albino rats were treated by injecting nicotine (1 mg/kg b.w. for 2 months) subcutaneously and thereby

In present research, the full-length cDNA and the genomic sequence of a novel cold-regulated gene, CsCOR1, were isolated from Camellia sinensis L. The deduced protein CsCOR1 contains a hydrophobic N-terminus as a signal peptide and a hydrophilic C-terminal domain that is rich in glycine, arginine

CONCLUSIONS Overexpression of CsHis in tobacco promoted chromatin condensation, but did not affect the phenotype. It also conferred tolerance to low-temperature, high-salinity, ABA, drought and oxidative stress in transgenic tobacco. H1 histone, as a major structural protein of higher-order

Tea (Camellia sinensis) is one of the richest sources of flavan-3-ols, an important class of flavonoids. The expression level of gene-encoded key regulatory enzymes of flavan-3-ol/anthocyanin biosynthetic pathway, dihydroflavonol 4-reductase (DFR) and anthocyanidin reductase (ANR), has been highly

Black tea is more widely consumed than green tea worldwide, particularly in India. Therefore, it is necessary to focus attention on black tea with respect to its health promoting and anti-cancer actions. In order to establish the concept that black tea is a potential candidate for cancer prevention,

Antimutagenic activity of green tea (Camellia sinensis) was studied using Salmonella typhimurium strains (TA 102) (Ames test). Aqueous tobacco extract was found to be mutagenic to S. typhimurium TA 102 at concentration of 50 mg/plate. Green tea polyphenols was found to inhibit the mutagenicity of

Male and female strain A/J mice were exposed to a mixture of cigarette sidestream and mainstream smoke at a chamber concentration of total suspended particulates of 82.5 mg/m3. Exposure time was 6 h/day, 5 days/week for 5 months. The animals were allowed to recover for another 4 months in filtered

Tea possesses a distinctive flavor profile and can have health benefits owing to the high levels of flavonoids in its leaves. However, the mechanism of the flavonoid glycosylation hasn't been well studied in tea plants, especially glycosylation at the 7-OH site has rarely been reported. In this

Nicotine is a parasympathomimetic alkaloid found in the nightshade family of plants (Solanaceae) and is a cholinergic drug. It acts directly by stimulating the nicotinic or muscarinic receptors or indirectly by inhibiting cholinesterase, promoting acetylcholine release, or by other mechanisms. 3% of

Endogenous nicotine was confirmed to be present in tea plants (Camellia sinensis L.) by liquid chromatography-tandem mass spectrometry of tea samples from tea-producing regions in six Asian countries. All samples contained nicotine (0.011-0.694 μg g-1 dry weight). Nicotine contents remained constant

OBJECTIVE To study the harmful effects of nicotine on the developing femur of chick and to observe the role of antioxidant camellia sinensis in the prevention of these effects. METHODS The experimental study was conducted at Army Medical College, Rawalpindi, from November 2, 2011, to November 1,

The aim of this study is to investigate the protective effect of green tea (GT) against the toxicity of nicotine. BALB/c mice were divided into four groups. Group I received food and water intake ad libidium, Group II received GT solution at a dose of 1 ml/kg body weight orally twice a day via

Cigarette smoke, specifically the nicotine contained within, has been shown to correlate closely with cell invasion and strategies to downregulate their expression may ultimately be of clinical utility. Matrix metalloproteinase-9 (MMP-9) is critically involved in the cell invasion and metastasis

OBJECTIVE Tobacco use has been identified as the most important environmental risk factor for periodontitis. The aim of this study was to investigate the effect of green tea epigallocatechin-3-gallate on the nicotine-induced toxic and inflammatory responses in oral epithelial cells and gingival

Strain A/J mice underwent whole body exposure for 6 hours a day, 5 days a week, for 5 months to a mixture of cigarette sidestream and mainstream smoke (89%-11%; total suspended particulates 80-150 mg/m3), then were kept for another 4 months in air before being killed for scoring of lung tumors. In 7
