| dihydrocapsaicin (dhc), a saturated structural analog of capsaicin, induces autophagy in human cancer cells in a catalase-regulated manner. | although capsaicin, a pungent component of red pepper, is known to induce apoptosis in several types of cancer cells, the mechanisms underlying capsaicin-induced cytotoxicity are unclear. here, we showed that dihydrocapsaicin (dhc), an analog of capsaicin, is a potential inducer of autophagy. dhc was more cytotoxic than capsaicin in hct116, mcf-7 and wi38 cell lines. capsaicin and dhc did not affect the sub-g(1) apoptotic peak, but induced g(0)/g(1) arrest in hct116 and mcf-7 cells. dhc caused t ... | 2008 | 18818525 |

| prevalence and toxigenic profiles of bacillus cereus isolated from dried red peppers, rice, and sunsik in korea. | bacillus cereus is a spore-forming foodborne pathogen responsible for diarrheal and emetic types of food poisoning. intoxication is caused by various enterotoxins or by emetic toxin. because of its widespread presence and the ability to form heat-stable endospores in a relatively short time, b. cereus has been difficult to control. in this study, 21 rice and 36 sunsik (a mixture of powdered raw grains) samples were examined for the prevalence of b. cereus. a multiplex pcr assay was used to evalu ... | 2009 | 19343947 |
| pepper chat fruit viroid: biological and molecular properties of a proposed new species of the genus pospiviroid. | in autumn 2006, a new disease was observed in a glasshouse-grown crop of sweet pepper (capsicum annuum l.) in the netherlands. fruit size of the infected plants was reduced up to 50%, and plant growth was also slightly reduced. here we show that the disease is caused by a previously non-described viroid. the pepper viroid is transmitted by both mechanical inoculation and pepper seeds and, when inoculated experimentally, it infects several solanaceous plant species inducing vein necrosis and redu ... | 2009 | 19442691 |

| effects of capsaicin, green tea and ch-19 sweet pepper on appetite and energy intake in humans in negative and positive energy balance. | bioactive ingredients have been shown to reduce appetite and energy intake. the magnitude of these effects might depend on energy balance why it was investigated how capsaicin, green tea, ch-19 sweet pepper as well as green tea and capsaicin affect appetite and energy intake during respectively negative and positive energy balance. | 2009 | 19345452 |
| effects of postharvest treatments on fruit quality of sweet pepper at low temperature. | postharvest storage of sweet pepper fruits (capsicum annuum l.) at low temperatures could impair their physical and chemical composition. therefore, maintenance of essential nutrition support or altered gas exchange could preserve fruit quality, minimizing chilling injury. thus our aim was to determine the response to postharvest application of a low concentration of nitrogen (urea) or antitranspirant (pinolene) during a period of 21 days at 5 °c. | 2010 | 20812372 |
| effect of foliar application of antitranspirant on photosynthesis and water relations of pepper plants under different levels of co2 and water stress. | strategies such as foliar application of antitranspirants have the potential to regulate transpiration, but often, the limitation of co(2) exchange as a result of reduced stomatal conductance can impair this beneficial effect. elevated ambient [co(2)] could significantly improve co(2) diffusion while effectively reducing transpiration. in this experiment, we examined the response of sweet pepper (capsicum annuum l.) to the foliar application of antitranspirant (at) under two [co(2)] (380 and 200 ... | 2010 | 20542351 |
| hydrophilic and lipophilic antioxidant capacities of georgian spices for meat and their possible health implications. | georgian cuisine is famous for its spices for meat dishes. many spices are rich in polyphenols and other antioxidants that reduce the formation of carcinogenic products during thermal processing of meat and counteract its adverse health effects. in spite of the relative popularity of meat dishes, georgia is characterized by low incidence of the colorectal cancer. we suggest that this phenomenon may be at least partially related to antioxidant-rich spices and other products of plant origin copiou ... | 2010 | 20234067 |

| capsaicin induces apoptosis through ubiquitin-proteasome system dysfunction. | capsaicin is an active component of red pepper having an antiproliferative effect in a variety of cancer cells, which recent evidence suggests due to its ability to induce apoptosis. however, the molecular mechanisms through which capsaicin induces apoptosis are not well understood. here we demonstrate that capsaicin-induced apoptosis is mediated via the inhibition cellular proteasome function. treatment of capsaicin to mouse neuro 2a cells results in the inhibition of proteasome activity in a d ... | 2010 | 20069556 |
| characterization of acc deaminase gene in pseudomonas entomophila strain ps-pjh isolated from the rhizosphere soil. | the enzyme 1-aminocyclopropane-1-carboxylate (acc) deaminase cleaves the ethylene precursor acc into alpha-ketobutyrate and ammonia. the decreased level of ethylene allows the plant to be more resistant to a wide environmental stress including plant pathogens. in the present study, we characterized the acc deaminase activity of a pseudomonas entomophila strain ps-pjh isolated from the red pepper rhizosphere region of red pepper grown at jinan, korea. the isolate produced 23.8 +/- 0.4 micromol of ... | 2010 | 20082369 |
| toward a quarter century of pathogen-derived resistance and practical approaches to plant virus disease control. | the concept of pathogen-derived resistance (pdr) describes the use of genetic elements from a pathogen's own genome to confer resistance in an otherwise susceptible host via genetic engineering [j. theor. biol. 113 (1985) 395]. illustrated with the bacteriophage qbeta in escherichia coli, this strategy was conceived as a broadly applicable approach to engineer resistance against pathogens. for plant viruses, the concept of pdr was validated with the creation of tobacco plants expressing the coat ... | 2010 | 20109666 |
| nsaid-activated gene-1 as a molecular target for capsaicin-induced apoptosis through a novel molecular mechanism involving gsk3beta, c/ebpbeta and atf3. | capsaicin, a natural product of the capsicum species of red peppers, is known to induce apoptosis and suppress growth. non-steroidal anti-inflammatory drug-activated gene-1 (nag-1) is a cytokine associated with pro-apoptotic and antitumorigenic property in colorectal and lung cancer. our data demonstrate that capsaicin leads to induction of apoptosis and up-regulates nag-1 gene expression at the transcriptional level. overexpression of ccaat/enhancer binding protein beta (c/ebpbeta) caused a sig ... | 2010 | 20110283 |
| capsiate inhibits ultraviolet b-induced skin inflammation by inhibiting src family kinases and epidermal growth factor receptor signaling. | capsiate, one of the major capsaicinoids, is nonpungent and present in sweet pepper. we investigated the effects of capsiate on the ultraviolet b (uvb)-induced inflammatory response in skin and its molecular mechanisms. capsiate-pretreated human keratinocytes inhibited intracellular reactive oxygen species (ros), which activate the mitogen-activated protein kinase and nuclear factor-kappab (nf-kappab) pathways. therefore, we determined the effects of capsiate on these pathways. capsiate inhibite ... | 2010 | 20123015 |
