Menaquinone 4 (MK-4) is the predominant homolog of vitamin K2 and is composed of a naphthoquinone base with four isoprenoid units in the side chain.1 It is formed primarily via conversion of vitamin K1 in vivo and accumulates in various tissues, including the brain.2,3 MK-4 halts the cell cycle at the G phase in HepG2, Hep3B, and Huh7 hepatocellular carcinoma cells in a concentration-dependent manner.4 It also inhibits IκB kinase (IKK) activity, IκBα phosphorylation, and the transcriptional activity of NF-κB. Vitamin K2 may have a role in bone metabolism.1

Cell experiment: |
Caco-2 cells are plated at a density of 2-5 × 104 cells/cm2 onto a 35-mm dish. Cells are incubated for 2 to 3 days until 60%-70% confluency, and desired concentrations of Menaquinone-4 (0, 1.0, 5.0, and 10.0 μM) are added. The final concentration of the vehicle is 0.1% of the culture medium, and the culture medium is changed twice a week. Cells are assayed on days 0, 3, 7, and 11 after the addition of Menaquinone-4[1]. |

Animal experiment: |
Forty-two male, 4-week-old C57BL/6J mice provided with feed and drink ad libitum. For environmental adaptation, the animals had 1 week of circulation, and then are provided with the experimental diet after being randomly divided into 6 groups (7 animals in each group; randomized block design). The AIN-93G diets consist of a normal diet (N), normal diet + vitamin K1 (N-K1), normal diet + vitamin Menaquinone-4 (N-K2), 45% high-fat diet (HF), 45% high-fat diet + vitamin K1 (HF-K1), and a 45% high-fat diet + vitamin Menaquinone-4 (HF-K2). The vitamin K1 and vitamin Menaquinone-4 contents are 200 mg/1,000 g, and the diet is provided in pellet form. Body weight is measured once a week, and the food efficiency ratio (FER) is calculated by dividing the increased body weight from day 1 to the final day by the food intake amount during the experiment period. For fat amount measurement, the epididymal fat, perirenal fat, and retroperitoneal fat are extracted from dead animal subjects, are washed with 0.9% NaCl, dried by filter paper, and then are weighed[2]. |

DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
