There are a sub-population of cells in tumor tissues known as cancer stem cells (CSCs) which have similar features with stem cells, including self-renewal and differentiation capacity. Recently, it was established that not only stem cells factors such as Oct4, but also ES-associated lncRNAs are contributing to various regulatory aspects of CSCs. Myocardial infarction associated transcript (MIAT...
amphiphilic cationic micelles have recently attracted much attention as non-viral vector. in the current study the retinoic acid-g-chitosan (ra-chitosan) micelles have been used as novel gene carriers. uptake of micelles, condensation ability and transfection efficiency of micelle–dna complexes (miceplexes) in the presence or absence of serum had been investigated on hela and hepg2 cell lines. ...
Isolation and identification of some potent anti-tumor compounds from medicinal plants, has motivated researchers to screen different parts of plant species for anti-tumor effects. It has been reported that several conifer posses cytotoxic activities on some human tumor cell lines. In this study, male and female branchlets or fruit of four different species of Iranian conifers (Juniperus Sabina...
Cytotoxicity of ICD-85 NPs on Human Cervical Carcinoma HeLa Cells through Caspase-8 Mediated Pathway
The biological application of nanoparticles (NPs) is a rapidly developing area of nanotechnology that raises new possibilities in the treatment of human cancers. The cytotoxicity was evaluated by MTT and LDH assays. The apoptotic effect of free ICD-85 and ICD-85 NPs on HeLa cells was assessed using caspase-8 colorimetric assay. The MTT assay showed that ICD-85 NPs could enhance the in-vitro cyt...

conclusions these results suggest that toxins induce inflammatory responses, particularly through expression of chemokine. recombinant stx and native toxin induced apoptosis by balancing between different pro- and anti-apoptotic bcl-2 family-factors in epithelial cells. in this study, for the first time, recombinant and native stx induction of apoptotic factors and stimulation of immune respons...
the objective of this study was to observe the apoptosis-inducing effect and mechanism of baicalin on human cervical cancer hela cells. the inhibitory effect of baicalin on the growth of hela cells was measured by mtt assay, and cell proliferation and migration was analyzed by cell scratch assay. morphological changes of apoptotic cells were viewed by the light microscope and electron microscop...
objective(s) the cytotoxic effects of crude ethanol extracts of some previously tested iranian conifers on tumor cell lines have motivated us to screen different parts of two subspecies in these genus. materials and methods terminal branchlets and berries of juniperus excelsa subsp. excelsa and j. excelsa subsp. polycarpos were collected, dried and extracted with ethanol/h2o (80/20 v/v) via pe...
