Life cycle, growth characteristics and host cell response of Rickettsia helvetica in a Vero cell line

In vitro studies of Rickettsia-host cell interactions: Confocal laser scanning microscopy of Rickettsia helvetica-infected eukaryotic cell lines

Rickettsia (R.) helvetica is the most prevalent rickettsia found in Ixodes ricinus ticks in Germany. Several studies reported antibodies against R. helvetica up to 12.5% in humans investigated, however, fulminant clinical cases are rare indicating a rather low pathogenicity compared to other rickettsiae. We investigated growth characteristics of R. helvetica isolate AS819 in two different eukar...

CYTOKINE AND GROWTH FACTOR MODULATION OF CELL CYCLE EVENTS IN HUMAN MELANOMA CELL LINES

Cytokines influence cell cycle events, which in some but not all instances can be associated with melanoma progression. Analysis of the G0/G 1 and S phase fractions of the cell cycle was used to assay the proliferative or inhibitory activity of cytokines against ten human melanoma cell lines, including pairs of cell lines derived from primary and metastatic tissue of individual patients. Cy...

evaluation of effect of as2o3 on cell growth, cell cycle and apoptosis in human leukemia cell line hl-60

introduction : arsenic trioxide (as2o3) causes antitumor effects by various mechanisms, including degradation of pml-rara in the acute promyelocytic cells, growth inhibition and induction of apoptosis. however, the precise mechanisms of these processes remain incompletely understood. the purpose of this study was to evaluate the effects of arsenic trioxide on cell growth, cell cycle regulation ...

Growth and persistent infection of African horse-sickness virus in a mosquito cell line

P.oleracea induced apoptosis and inhibited the cell growth in oral epithelial cancer cell line

Despite the progress in cancer therapies such as chemotherapy and radiation, its eradication remains as unattainable dream for the patients and doctors. Recently, using supplementary agents such as herbal medicine with fewer side effects seems efficient and attractive. Therefore, the purpose of the present study is to investigate if the ethanolic extract of P.oleracea has cytotoxicity and apopt...
