About this deal
Vitamin K2-7 is taken in the form of drug (capsules) or included in dietary supplements such as dairy products (yoghurt, cheese, etc). The mechanistic basis for the disease-modulating effects of K2-7 is mediated through various signal transduction pathways such as PI3K/AKT, MAP Kinase, JAK/STAT, NF-κB, etc. studied the effect of vitamin K2-7 (with and without vitamin D3) on differentiation of human mesenchymal stem cells (hMSCs) obtained from bone marrow. Vitamin K2 Supplementation Does Not Influence Bone Loss in Early Menopausal Women: a Randomised Double-Blind Placebo-Controlled Trial.
Vitamin K2 inhibited the nuclear translocation of NF-κB in MG6 cells induced by LPS, resulting in inhibition of NF-κB signaling. In a subsequent study, five healthy female subjects were administered with 60 μg of MK-7 daily after supper for 7 days. The serum samples showed increase in MK-7 and decrease in circulating ucOC concentration ( van Summeren et al. Some of the trials on vitamin K2-7 that enrolled people with chronic diseases such as diabetes were limited to 8–12 weeks duration. Bone mineralization is influenced by osteocalcin as it has high affinity towards hydroxyapatite, a mineral component of bone; this results in stronger skeleton and less susceptibility to fracture ( Hoang et al.It also helps regulate the immune system, reduce inflammation, and may play a role in helping protect against certain diseases. Phase 1 Study of Combination Strontium, Melatonin and Nutritional Co-factors on Bone Health and Quality of Life in Postmenopausal Women with Osteopenia.
The medium used for the production was glycerol-based as it is relatively cheaper compared to other carbon sources like sucrose, glucose and mannose and can also improve the production of vitamin K2-7. Therefore, to gain the ability to bind to hydroxyapatite, calcium and BMP-2 MGP is required to be carboxylated as well as phosphorylated ( Figure 4) ( Wallin et al. Interestingly, K2-7 is also responsible for suppression of proinflammatory mediators such as IL-1α, IL-1β and TNF-α. NF-κB is a nuclear transcription factor and associates itself with cell growth by regulation of the cyclin D1 gene ( Xia et al.
Vitamin K2-7, also known as menaquinone-7 (MK-7) is a form of vitamin K that has health-beneficial effects in osteoporosis, cardiovascular disease, inflammation, cancer, Alzheimer’s disease, diabetes and peripheral neuropathy. In addition, statin inhibited activity of VKDPs and calcium accumulation was increased in arterial walls. Biphasic decline of MK-7 was observed during the 2-week washout period with a T 1/2 of 3 and 8 days during the first phase and second phase, respectively.
