Menaquinone-7 (Vitamin K2-7), a highly valuable member of the vitamin K series, has significant effects on preventing osteoporosis and cardiovascular disease besides its positive effects on blood coagulation [1].
Menaquinone-7 (10 µM) treated MC3T3E1 cells for 24, 48, 96 and 240 h, no statistical differences at 24, 48 and 96 h, the growth of MK-7 treated cells was significantly suppressed at 240 h. Menaquinone-7 increased osteocalcin, osteoprotegerin, and RANKL mRNA expression in osteoblastic MC3T3E cells [2]. After 24 h of Menaquinone-7 administration, genes upregulated by Menaquinone-7 included tenascin C and BMP2. Genes downregulated by Menaquinone-7 administration included biglycan and butyrophilin [3]. Menaquinone-7 (1 µM) increases alkaline phosphatase activity and calcium content in femoral-metaphyseal tissues isolated from normal and skeletal-unloaded rats [4]. Menaquinone-7 (10 µM) promotes osteoblast maturation thereby increasing osteogenic differentiation [5].
Menaquinone-7 increased The bone formation marker osteocalcin (OC), which is the bone formation marker [6]. Menaquinone-7 (200 mg/1,000 g fed with diets) supplementation decreases the bone resorption index and increases the bone formation index, balancing bone metabolism, and is considered to prevent bone loss [6].
