Cytotoxicity of Subtoxic AgNP in Human Hepatoma Cell Line (HepG2) after Long-Term Exposure

Background: We aimed at evaluating the toxicity effects of low (subtoxic) concentrations of silver nanoparticles (AgNP, 5-10 nm) in human hepatoblastoma (HepG2) cell line after and during a period of about one month. Methods: XTT and MTT assays were used to draw a dose-response curve IC50 (half maximal inhibitory concentration) value of the AgNP on HepG2 cells was calculated to be 2.75-3.0 mg/l...

Antioxidant Effects of Pinus Eldarica Extracts Against Cisplatin-Induced Cytotoxicity in Human Hepatoma (Hepg2) Cell Line

Background:  Cisplatin has cytotoxic effects through free radical generation. Reports indicate that various members of Pinaceae family may have antioxidant properties. In this study we investigated the cytoprotective effects of needle volatile oil and bark extract of Pinus eldarica in hepatoma G2 (HepG2) cell line.  Methods: Using the maceration technique, we obtained the ethanolic extract of ...

Comparison of the cytotoxicity of high-level disinfectants by the MTT assay and direct contact assay.

Most critical instruments are not designed for heat sterilization and autoclaving. These items are usually treated with chemical agents such as peracetic acid(PAA), glutaraldehyde (GA) and ortho-phthalaldehyde (OPA). MTT assay is often used to evaluate the in vitro cytotoxicity of these chemical agents. In this study, disinfectants were allowed to come in direct contact with cells. Their cytoto...

Genotoxic effect induced by hydrogen peroxide in human hepatoma cells using comet assay

BACKGROUND Hydrogen peroxide (H(2)O(2)) is a common reactive oxygen intermediate generated by various forms of oxidative stress. AIM The aim of this study was to investigate the DNA damage capacity of H(2)O(2) in HepG2 cells. METHODS Cells were treated with H(2)O(2) at concentrations of 25 µM or 50 µM for 5 min, 30 min, 40 min, 1 h, or 24 h in parallel. The extent of DNA damage was assessed...

Comparison of MTT, trypan blue, and clonogenic assay, to determine the viability in human anaplastic thyroid cancer cell line

Background: Evaluation of cell viability is momentous in pharmacologic and oncological research. Cell viability evaluation determines cell sensitivity and consequently treatment outcome. Various methods are available to determine cell survival. Each of these methods evaluates different endpoints. Accordingly, determining the correlation between these methods is important. In this study, in orde...
