We have previously developed a human macrophage hybridoma model system to study the effect of HIV-1 infection on monocytic function. Upon coculture of one chronically (35 days postinfection) HIV-1-infected human macrophage hybridoma cell line, 43HIV, there was a dose-dependent decrease in the viability of cocultured Ag-stimulated T cells associated with an increase in DNA strand breaks. Enhance...
Many red algae-derived natural products are known to have anticancer effects. The biological functions of the red alga Solieria robusta from the Karachi coast (Pakistan) remain unclear. Here, we prepared a methanolic extracts of S. robusta (MESR) to examine its possible anti-oral cancer effects and the corresponding mechanism of action. Cell viability of MESR-incubated oral cancer Ca9-22 cells ...
OBJECTIVES The effects of chlorine dioxide (ClO2), sodium hypochlorite (NaOCl), and hydrogen peroxide (H2O2) on cell death and the cell cycle of human gingival fibroblast (HGF) cells were examined. METHODS The inhibition of HGF cell growth was evaluated using a Cell Counting Kit-8. The cell cycle was assessed with propidium iodide-stained cells (distribution of cells in G0/G1, S, and G2/M pha...
We used immunohistochemistry and flow cytometry to assess apoptosis in human glioblastoma multiforme (GBM). Our immunohistochemical study revealed apoptosis of glioma cells expressing glial fibrillary acidic protein and of CD3(+) T cells infiltrating GBM. To quantify and phenotype the apoptotic T cells, we performed flow cytometry on lymphocytes separated from GBM. The cells were stained with a...
Viruses have great potential as nanotools in medicine for gene transfer, targeted gene delivery, and oncolytic cancer virotherapy. Here we have studied cell death mechanisms of canine parvovirus (CPV) to increase the knowledge on the CPV life cycle in order to facilitate the development of better parvovirus vectors. Morphological studies of CPV-infected Norden laboratory feline kidney (NLFK) ce...
In the present study, we aimed to investigate the relationship between autophagy and apoptosis in selenite‑treated colorectal cancer (CRC) cells. The effects of selenite on HCT116 and SW480 cell apoptosis were investigated with an Annexin V/propidium iodide (PI) double staining kit by flow cytometry. The punctate of LC3 protein following treatment with selenite was observed by a laser scanning ...
Intake of fruits rich in antioxidants in daily diet is suggested to be cancer preventive. Sapota is a tropical fruit grown and consumed extensively in several countries including India and Mexico. Here we show that methanolic extracts of Sapota fruit (MESF) induces cytotoxicity in a dose-dependent manner in cancer cell lines. Cell cycle analysis suggested activation of apoptosis, without arrest...
G6P translocase (G6PT) is thought to play a crucial role in transducing intracellular signaling events in brain tumor-derived cancer cells. In this report, we investigated the contribution of G6PT to the control of U-87 brain tumor-derived glioma cell survival using small interfering RNA (siRNA)-mediated suppression of G6PT. Three siRNA constructs were generated and found to suppress up to 91% ...
Methylglyoxal (MG) is a ubiquitous metabolite derived from glycolysis; however, this aldehyde kills all types of cell. We analyzed the properties of MG-induced cell death of the budding yeast Saccharomyces cerevisiae. The MCA1 gene encodes a caspase homologue that is involved in H2O2-induced apoptosis in yeast, although the disruption of MCA1 did not repress sensitivity to MG. In addition, the ...
مقدمه: ترکیبات پلی فنلی دارای اثر ضد تکثیر(آنتی پرولیفراتیو) و محرک آپوپتوز در سلول های سرطانی هستند. پی-کوماریک اسید به طور گسترده ای در میوه ها، سبزی ها، محصولات گیاهی و عسل یافت می شود. از طرفی دیگر سرطان پستان، در دنیا شایع ترین سرطان در زنان است. هدف از مطالعه حاضر، بررسی اثر ضد سرطانی پی-کوماریک اسید بر سلول های سرطان پستان رده mcf-7 بود. روش بررسی: به منظور بررسی اثر آپوپتوزی پی-کوماریک ...
