A micro-tetrazolium assay was employed to evaluate vitamin C (VC), vitamin K-3 (VK3) and vitamin C/vitamin K-3 combinations (VC/VK3) for their antitumor activity against eight human urologic tumor cell lines. While the individual vitamins exhibited…
Transmission and scanning electron microscopy and flow cytometry were employed to characterize the cytotoxic effects of vitamin C (VC), vitamin K3 (VK3), or VC-VK3 combinations on a human prostate carcinoma cell line (DU145) following a 1-h vitamin…
Vitamins C, K3 (VC, VK3) and a VC/VK3 combination with a VC:VK3 ratio of 100:1 were assayed for their antitumour activity against two human prostatic carcinoma cell lines. Co-administration of the vitamins enhanced the antitumour activity 5- to…
Immortalized human lymphoid cells treated with Methyl-2,5-dihydroxycinnamate (MDHC), a stable analog of erbstatin, inhibited the G2/M transition of the cell cycle. The MDHC inhibition of the cell cycle was observed at concentrations well below the…
