High Dose Vitamin B1 Reduces Proliferation in Cancer Cell Lines Analogous to Dichloroacetate
Hanberry BS, Berger R, et al, Cancer Chemother Pharmacol, 2014 Jan 23; [Epub ahead of print].
In a cell culture study involving pancreatic cancer cells, high dose thiamine (vitamin B1) was found to reduce "cancer cell proliferation by a mechanism similar to that described for dichloroacetate." Administration of thiamine was found to exhibit a lower IC50 value, as compared to DCA, and both thiamine and DCA reduced the extent of PDH phosphorylation, reduced glucose consumption, lactate production, and mitochondrial membrane potential, and increases caspase-3 activity.
