Influence of genetic variability on specialty potato functional components and their effect on prostate cancer cell lines

Reddivari, Lavanya 15 May 2009 (has links)
The influence of genotype (selection), location, and year on antioxidant activity (AOA), total phenolics (TP), total carotenoids (TC), phenolic and carotenoid composition was studied using specialty (colored) potatoes (Solanum tuberosum L.) from the Texas Potato Variety Development Program, grown at two Texas locations (McCook and Dalhart), and in two years (2003 and 2004). Chlorogenic acid, gallic acid, catechin, caffeic acid, and malvidin-3-(p-coumaryl rutinoside)–5-galactoside were the major phenolics, and lutein and violaxanthin were the major carotenoids identified. The AOA, TP, and TC and phenolic composition differed significantly with genotype, location and year. However, genotypic effects were larger than location and year effects. Selection CO112F2-2 was high in all the measured parameters and also stable across locations and years, suggesting that this selection could be used as a parent in breeding varieties with improved health benefits. The AOA, TP and chlorogenic acid content were highly significantly correlated with one another. The effects of whole specialty potato extracts, fractions and individual compounds on LNCaP (androgen-dependent) and PC-3 (androgen-independent) prostate cancer cells were also investigated. Ethanol extract of the selection CO112F2-2 (5 µg chlorogenic acid eq/ml), the anthocyanin fraction (AF; 5 µg chlorogenic acid eq/ml), gallic acid and chaconine showed potent anti-proliferative properties and increased the cyclin-dependent kinase inhibitor p27 levels in LNCaP and PC-3 cells. Induction of apoptosis was cell context dependent and associated with JNK (c-Jun NH2-terminal Kinase) and Erk (extracellular signal regulated kinase) activation. Cell death pathways, induced by potato extract and the AF, were associated with Erk and JNK activation, and these kinases activated caspase-independent apoptosis through nuclear translocation of endonuclease G (endo G) and apoptosis-inducing factor (AIF) in both cell lines. Induction of caspase-dependent apoptosis was also kinase-dependent but was observed only in LNCaP cells. Kinase inhibitors reversed this nuclear translocation of endo G and AIF. This is the first report showing that the cytotoxic activities of potato extract/AF in cancer cells were due to activation of caspase-independent apoptosis.

Effect of the antidepressant mirtazapine on intracellular Ca2+ signals and proliferation of prostate cancer PC3 and osteosarcoma MG63 cells

Pan, Chih-chuan 12 July 2005 (has links)
The effects of the antidepressant mirtazapine on cytosolic Ca2+ concentrations ([Ca2+]i) in human prostate cancer PC3 cells and human osteosarcoma MG63 cells were measured by Ca2+-sensitive fluorescent probe fura-2. In Ca2+-containing medium, mirtazapine induced [Ca2+]i rises in a concentration-dependent manner in both PC3 and MG63 cells. Removal of extracellular Ca2+ inhibited the mirtazapine-induced Ca2+ signal. In Ca2+-free medium, thapsigargin (an inhibitor of the endoplasmic reticulum Ca2+-ATPase pump) induced [Ca2+]i rises by passively depleting the endoplasmic reticulum Ca2+ store, after which the increasing effect of mirtazapine (1.5 mM) on [Ca2+]i was reduced. Conversely, pretreatment with mirtazapine decreased thapsigargin-induced [Ca2+]i rises in PC3 and MG63 cells. When PC3 cells were pretreated with U73122, a phospholipase C inhibitor, mirtazapine-induced [Ca2+]i rises were inhibited by 47%. But in MG63 cells, 2 mM U73122 did not change mirtazapine-induced [Ca2+]i rises. These finding suggest that mirtazapine-induced [Ca2+]i rises were caused both by extracellular Ca2+ influx and intracellular depletion of the endoplasmic reticulum Ca2+ stores. Furthermore, the mechanism of mirtazapine-induced Ca2+ release may be different between PC3 and MG63 cells. Additionally, cell proliferation assays suggest that overnight incubation with higher concentrations of mirtazapine decreased cell viability in a concentration-dependent manner.

Membrane insertion and secretion of the Engrailed-2 (EN2) transcription factor by prostate cancer cells may induce antiviral activity in the stroma

Punia, N., Primon, Monika, Simpson, G.R., Pandha, H.S., Morgan, Richard 26 March 2019 (has links)
Yes / Engrailed-2 (EN2) is a homeodomain-containing transcription factor that has roles in boundary formation and neural guidance in early development, but which is also expressed in a range of cancers. In addition to transcriptional regulation, it is secreted by cells and taken up by others through a mechanism that is yet to be fully elucidated. In this study, the distribution of EN2 protein in cells was evaluated using immunofluorescence with a set of antibodies raised against overlapping epitopes across the protein, and through the use of an EN2-GFP construct. MX2 expression in primary prostate tumors was evaluated using immunohistochemistry. We showed that EN2 protein is present in the cell membrane and within microvesicles that can be secreted from the cell and taken up by others. When taken up by normal cells from the stroma EN2 induces the expression of MX2 (MxB), a protein that has a key role in the innate immune response to viruses. Our findings indicate that EN2 secretion by tumors may be a means of preventing viral-mediated immune invasion of tissue immediately adjacent to the tumor. / The Ringrose Family Trust supported this study through a studentship awarded to N.P.
