Summary: | The aim of this study is to investigate the effect of 1-131 on different type of
cancer cell lines. HeLa, T24, and DBTRG-05 cells exposed to radioiodine-131 of activity
100, 200, 300, 400, and 500 pCi were incubated at 37°C temperature in 1 hour, 2
hours and 3 hours. The cells then washed with PBS and being trypsinized followed
by performing measurement using well counter to acquire the cell counts.
Percentage uptake was calculated, proceeded with the cells viability and
clonogenic assay procedure. HeLa cells uptake was found to be inversely correlated to the radioactivity
and uptake by DBTRG-05 cells was significantly high than compare to HeLa and
T24 cells. T24 cells uptake was increased with activity in 3 hours incubation time.
As for the cells viability, result obtained was increased by time in HeLa that reverse
to T24 and DBTRG-05 cells which viability was reduced by time but the viability
with respect to activity was not significantly obtained. Meanwhile, the use of high
activity 1-131 within few days was found suppressed the proliferation of cancer cells
especially for DBTRG-05 cells followed by T24 and HeLa..
The findings of this study suggest that the cellular uptake of 1-131,
cells viability and proliferation were highly dependent on cells metabolism, mitotic
rate, occurrence of apoptosis, doubling time, cells radiosensitivity, and so on with
consideration of some limitations.
