Erroneous Laboratory Operation May Lead To a Cancer Drug

...cording to Schaefer, mode of action of PPAR-gamma is different from the current drugs. It attacks a section of cell cytoskeleton called tubulin. While tubulin is involved in building the cell arrangement, PPAR-gamma breaks it down. This indirectly indicates that the gamma compound could actually counter the ...
