Drug response assay system in a microchip using human hepatoma cells.
A microchip-based cell response assay system to an anticancer agent was developed. The hepatoma cell line HepG2 was used to assess the effects of an anticancer agent, doxorubicin. The required cell number was reduced by two orders, and the observation of the time course of cell response became possible. The system clearly showed that treatment with higher doses of the drug or longer exposure ti...
متن کاملRadioadaptive Response in Human Lymphocyte Cells
The adaptive response (AR) is a phenomenon by which cells exposure to sublethal doses of DNA-damaging agents (non-mutagenic dose of chemical or radiation), known as conditioning treatment (CT), leads to increased resistance to a subsequent exposure to a higher dose of the same or other agents, known as challenge treatment (CR). The adaptive response (AR) induced by radiation in human lymphocyte...
متن کاملGenotoxic 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...
متن کاملCulture and leukocyte adhesion assay of human arterial endothelial cells in a glass microchip.
Cells are frequently exploited as processing components for integrated chemical systems, such as biochemical reactors and bioassay systems. By culturing vascular endothelial cells (ECs) in integrated chemical devices, vascular models have also been fabricated. Here, we utilized a thermally fused-glass microchip which is chemically and physically stable and favorable for optical detections, and ...
متن کاملExpression of CXC Chemokines Gro/KC and SDF-1a in Rat H4 Hepatoma Cells in Response to Different Stimuli
Background: It is now well established that several environmental stress factors cause activation of p38 MAP kinase and JNK in various cell types to produce chemokines. Objective: To investigate the expression of CXC chemokines Gro/KC and SDF- 1a in rat's H4 hepatoma cells in response to heat shock, hyperosmolarity and oxidative stress. Methods: Hepatoma cells were maintained in MEM medium. Cel...
