From: Menaquinone-4 enhances testosterone production in rats and testis-derived tumor cells
Warfarin does not inhibit enhanced testosterone production by menaquinone-4 in I-10 cells. I-10 cells were treated with warfarin and menaquinone-4 (MK-4) simultaneously for 24 h, and testosterone levels in the culture medium were then determined by ELISA. Data are represented as means ± SE (n = 3). Values indicated with different letters are significantly different at p < 0.05.
