The study authors found that the cell growth and radiosensitivity of the malignant tumor cells were not affected by any of the supplements, but two of the supplements inhibited the growth rate of the normal prostate cell lines while a third supplement also increased the cellular radiosensitivity of some normal cell lines by inhibiting DNA repair.
-
Prostate-specific dietary supplements should not be taken during radiation therapy treatments because they have been shown to increase the radiosensitivity of normal prostate cell lines, leading to normal tissue complications, according to a study in the March issue of the

Researchers at William Beaumont Hospital in Royal Oak, Michigan, have suggested that during radiation therapy treatments prostate-specific dietary supplements should not be taken as they increase the radiosensitivity of normal prostate cell lines, leading to normal tissue complications.

We have previously shown that radiosensitivity of human tumor cells segregate non-randomly into a limited number of groups.
-
However we have also shown that abrogation of a single gene (p21) in a human tumor cell unexpectedly sensitized xenograft tumors comprised of these cells to radiotherapy while not affecting in vitro cellular radiosensitivity.
-
In the current work, we measure in vitro radiosensitivity and in vivo response of their xenograft tumors in a series of human tumor lines that represent the range of radiosensitivity observed in human tumor cells.
-
We assayed in vitro survival patterns in eight tumor cell lines that vary in cellular radiosensitivity and genotype.
-
In this respect, individuals with ATM (ataxia telangiectasia) related anomalies are of particular interest becausse of their association with increased risk of both breast cancer and clinical radiosensitivity.
