In Vitro Effect of Ciprofloxacin on HT-29 Human Colon Carcinoma Cell Line: Assessment of Cell Proliferation by Thymidine Uptake and Silver Nucleolar Organizer Regions (AgNOR) Histomorphometry
Overview
Affiliations
In an in vitro study, the effect of ciprofloxacin was examined on proliferation of HT-29 human colon carcinoma cell line. Cell proliferation was measured by 3H-thymidine uptake and silver nucleolar organizer region (AgNOR) histomorphometry. A significant increase in [3H]thymidine incorporation (p < 0.05) parallel with a significant increase in the mean AgNOR clusters/cells (p < 0.01) was noted after 5 days of cell exposure to ciprofloxacin. It is suggested that the assessment of AgNOR variables is useful in examination of quinolone effect on HT-29 human colon carcinoma cell proliferation.
