The µ-opioid receptor is the primary site for the action of morphine. In the present study, we investigated the regulation of the µ-opioid receptor mRNA levels in the locus ceruleus, ventral tegmental area, nucleus accumbens and hypothalamus of the rat brain following intracerebroventricular administration of morphine for 7 days. The isolated mRNA from(More)
BACKGROUND Prostate cancer is the second most common cause of mortality. Gallic acid (GA) is a natural polyphenol, and we tested its in-vitro cytotoxicity after 24 h in prostate cancer LNCaP cells. MATERIALS AND METHODS GA autoxidation was measured fluorimetrically for H(2)O(2), and O(2)(•-) radicals by chemiluminescence. Intracellular reactive oxygen(More)
Morphine is an effective analgesic that acts by binding to the µ-opioid receptor (MOR) coded in the human by the OPRM1 gene. In the present study, we investigated the regulation of µ-opioid receptor (MOR-1) mRNA levels in all-trans-retinoic acid-differentiated SH-SY5Y human neuroblastoma cells under in vitro conditions with 10 µM morphine treatment for 24(More)
BACKGROUND Prostate cancer is one of the most commonly diagnosed solid malignancies among US men. We identified gallic acid (GA) as a major bioactive cytotoxic constituent of a polyherbal Ayurvedic formulation - triphala (TPL). Both TPL and GA were evaluated on (AR)(+) LNCaP prostate cancer and normal epithelial cells. MATERIALS AND METHODS Total(More)
The main objective of this paper was to investigate the extraction process of ethanol extract of Radix Semiaquilegiae, as well as its inhibitory activity on human hepatoma HepG-2 and SMMC-7721 cells, and to compare the inhibitory effects of different concentrations of ethanol extracts against these two hepatoma cells. Ethanol reflux extraction and(More)
