In vitro cytokinetic response of human colon cancer cells to cis-dichlorodiammineplatinum(II).

چکیده
The cytokinetic response of a human colon carcinoma cell line to cis-dichlorodiammineplatinum(II) was investigated using flow cytometry of DNA content, autoradiography after pulse and continuous tritiated thymidine exposure, and mitotic accumulation after continuous Colcemid treatment. With increasing concentration and exposure time, cis-dichlorodiammineplatinum(II) delayed and then blocked cycle traverse in S and G2 phases. After prolonged treatment with high concentrations of cis-dichlorodiammineplatinum(II), an additional block in G1 or at the G1-S boundary was established. Irreversibility of cell cycle distribution changes after prolonged observation periods suggests cell death in G2, S, and G1 compartments.

The thermosensitivity of human colon adenocarcinoma (LoVo) cells was investigated as a function of temperature and duration of heating in exponentially growing cultures. At 39-43 degrees, time-dependent survival followed a simple exponential function. Do values decreased progressively with a rise in temperature, from Do at 40 degrees = 38 hr to Do at 42 degrees = 17 hr to Do at 43 degrees = 1.5...

Two rabbits were immunized with native DNA modified in vitro by cis-dichlorodiammineplatinum(II) (cis-Pt). The interactions between the antiserum and several natural and synthetic nucleic acids were studied primarily by radioimmunoassays. Native DNA's modified by platinum compounds with labile groups in the cis position are recognized by the antiserum. No cross-reaction is found with native DNA...

Introduction: Radiation therapy is an important procedure for treatment of more than half of tumors. One way to increase the efficiency of radiation therapy is application of radiosensitizer at the site of tumor. gold nanoparticles (GNPs) have several characteristics that make them attractive for using with radiation therapy including small size (1–100 nm), biocompatibility, pr...
متن کاملAnticancer Properties of Chrysin on Colon Cancer Cells, In vitro and In vivo with Modulation of Caspase-3, -9, Bax and Sall4
Background: The SALL4/Sall4 is constitutively expressed in human and mice. SALL4 mRNA could be used as a marker for the diagnosis of different types of cancers. On the other hand, chrysin has diverse biological properties. Objectives: In the present study, the effect of the chrysin was investigated on the CT26 colon cancer in vitro and in vivo. Furthermore, the expression levels of the stem cel...
