A simple in vitro expt could be done.. I think I could have such data gathered, but it would COST time.. ANd I'm not positive the demand is high enough...
A general tissue culture viability expt along with p53 Western would get us started... A Western will tell us if p53 is up-regulated or not. An increase in this protein is usually a good indicator of bad things occuring in the cell. Such things that would warrant DNA repair, apoptosis machinery.
If this data becomes interesting, co-treatment with anti-oxidants and/or other drugs may provide more feedback.
Like I said, I would be willing to see it done.. And it would not be any real expense to an appropriately equipped lab.. But time is money.
