Transketolase has been purified for the first time from human leukocytes, according to a new procedure which consists of three conventional steps. The enzyme was finally detached from CM-cellulose by specific elution with a D-xylulose-5-phosphate/D-ribose-5-phosphate mixture and the isolated product

Cisplatin is a mainstay of cancer chemotherapy. It forms DNA adducts, thereby activating poly(ADP-ribose) polymerases (PARPs) to initiate DNA repair. The PARP substrate NAD+ is synthesized from 5-phosphoribose-1-pyrophosphate (PRPP), and we found that treating cells for 6 h with cisplatin reduced
