objective(s): valproic acid (vpa) has proven to be as one of the most promising useful drug with anticancer properties.in this study, we investigate the vpa effects on e-cadherin expression in hela, tc1, mkn45, and hct116 cell lines.  this study assesses the effects of vpa on human papillomavirus e7 expression in hpv positive cell lines. materials and methods: cell lines were treated by2 mmol/l...

Estradiol valerate (Exogenous estrogen) is a synthetic ester and is also a female estrogen hormone. There arestudies showing that estradiol may have anticancer effects. This study was performed to reveal the effects ofexogenous estrogens on the viability of cervical cancer cells in cell culture. We used Hela cells as our cell linein this study. Hela cells were exposed to 0.0001, 0.001, 0.01, 0....

The impact of radiation-induced bystander effect (RIBE) is still not well understood in radiotherapy. RIBEs are biological effects expressed by nonirradiated cells near or far from the irradiated cells. Most radiological studies on cancer have been based biochemical characterization. However, biophysical investigation with label-free techniques to analyze and compare direct irradiation RIBE has...

objective: cervical cancer is the second most common cause of death from cancer in women throughout the world. the aim of this study was to evaluate the cytotoxic activity of kelussia odoratissima (k. odoratissima) extract associated with radiotherapy in cervical cancer cells (hela cell line).materials and methods: different concentration of the extract (25-500µg/ml) was tested in hela cell lin...

Objective(s): Mitofilin contributes to the maintenance of mitochondrial structure and functions. This study was undertaken to determine the mechanisms underlying its regulation of apoptosis.  Materials and Methods: Mitofilin was knockdowned by specific short hairpin RNA (shRNA) and the stable HeLa cell clone was selected. The autophagy a...

the anti-cancer activity of metal ions in the lanthanide group is being considered recently. it has been reported that cerium salts might stimulate the metabolism and therefore, produce anti-cancer effects. however, little is known about the effects of protein-cerium complex in controlling cancer cell growth. the aim of the present study was to elucidate the possible pathways for the cytotoxic ...

background and objective: in addition to the use of chemicals in food, pharmaceutical, cosmetic and hygiene industries, use of herbal and natural compounds have also increased. it seems natural ingredients compared with the chemical components show less side effects, such as mutagenicity and carcinogenesis however, their use can also be associated with side effects and toxicity. some significan...
