After washing the cells twice with DMEM containing no fetal bovine serum, Using a culture containing S xl O ⁇ mol 1 insulin The culture medium was incubated at 37 ° C in a 5% C0 2 incubator for 16 ho. This was used as a model cell for HepG 2 cells incubated with insulin-containing medium for 16 h.
- the prepared cell suspension was counted, and the cell concentration was adjusted to 5 ⁇ 10 4 ⁇ ⁇ .
- the cells were seeded in a 96-well cell culture plate, and each group was provided with 8 replicate wells, each of which was 200 ⁇ M.
- the experiment was divided into 5 groups: normal control group, insulin resistance model group, compound sea cucumber preparation high and low dose group and metformin positive control group. Except the normal control group, the other groups were incubated with the final concentration of Sx lO ⁇ moH 1 insulin for 16 h to induce insulin resistance.
- the cells were incubated with the insulin-free medium, and each of the administration groups was incubated with a final concentration of a compound sea cucumber preparation 2.5 g_lA compound sea cucumber preparation 5.0 g_lA metformin 30 mg 1 in a culture medium. After 24 hours of administration, the glucose in the culture solution was detected by glucose oxidase method, and the sugar contained in the unrecovered cells was used.
- the mean value is subtracted and the glucose consumption of each well cell is calculated.
- the GPO-POD enzymatic method was used to determine the glycerol content in the culture solution, and the average glycerol content in the unrecovered cell blank was subtracted, and the glycerol consumption of each well cell was calculated.
- the MTT stock solution of Sg.L and the serum-free DMEM medium were mixed into MTT medium in a volume of 1:9.
- the culture solution was removed, and MTT culture solution was added to each well, 37 °. C continued the culture, and the culture was terminated after 4 hours, and the culture supernatant in the well was carefully aspirated, 200 L of dimethyl sulfoxide was added per well, and the crystal was shaken for 10 min to dissolve the crystal at a wavelength of 570 nm in a microplate reader.
- the absorbance values of the respective wells were measured, and the % survival of the cells was calculated to evaluate the effect of the drug on cell proliferation.
- Type group ⁇ 40 ⁇ .00 .00 .00 .31 2.57 ⁇
