line used in the present study is human cervical cancer cell line,
HeLa cells, obtained from National Centre for Cell Science, Pune,
India. For maintenance of cell lines, Dulbecco’s modified Eagle’s
medium (Sigma-Aldrich) containing 10% fetal bovine serum (Gibco),
antibiotics (100 U/mL penicillin and 100 μg/mL streptomycin),
and amphotericin (0.25 μg/mL) (HiMedia) were employed. The cells
were maintained in CO2 incubators at 37 °C with 5%
CO2 in air and 99% humidity. The passaging of cells when
confluent was carried out using 0.25% trypsin and 0.02% ethylenediaminetetraacetic
acid (HiMedia) in phosphate-buffered saline. Experiments were carried
out after 36 h of seeding the cells at appropriate density in suitable
well plates.
