Measurement of Insulin Resistance and Triglycerides

Blood was collected from the heart, and the fasting blood glucose level was measured. The blood samples were left at room temperature for 2 h, and then centrifuged at 1,000 × g for 20 min. The supernatant was collected, and the serum insulin content was detected using an INS ELISA kit (E-EL-M1382c; Elabscience, Wuhan, China). Finally, the homeostatic model assessment for insulin resistance (HOMA-IR) index and the homeostatic model assessment for insulin sensitivity index (HOMA-ISI) of each group were calculated using the following formulae (Fang et al., 2010 (link)): insulin resistance index = [fasting blood glucose (mmol/L) × serum insulin (mIU/L)] / 22.5; insulin sensitivity index = 1 / [fasting blood glucose (mmol/L) × serum insulin (mIU/L)]. Triglycerides (TGs) in the liver tissue or serum were measured using a TG assay kit (E-BC-K261; Elabscience, Wuhan, China).

Plasma insulin (E-EL-M1382c, Elabscience, Wuhan, China), GLP-1 (E-EL-M3012, Elabscience), TNF-α (RK00027, ABclonal, Wuhan, China), IL-6 (RK00008, ABclonal), and IL-4 (RK00036, ABclonal) levels were determined via ELISA according to the manufacture’s protocols. Total cholesterol (A111-1-1), triglyceride (A110-1-1), low-density lipoprotein cholesterol (A113-1-1), and high-density lipoprotein cholesterol (A112-1-1) were measured using relative commercial colorimetric enzymatic assay kits from Najing Jiancheng Bioengineering, as described previously [25 (link)].

ELISA kits for mouse ghrelin (E-EL-M0551c; Elabscience), insulin (E-EL-M1382c, Elabscience), GLP-1 (E-EL-M3012; Elabscience), and PYY (E-EL-M2375c; Elabscience) were purchased from BGsciences Biotechnology Co., Ltd. (Guangzhou, China). ELISA was performed using serum samples. Blood samples were obtained from heart and allowed to clot for 30 min at 37 °C. After centrifugation at 2000g for 15 min, the serum was collected from the blood samples. Serum was used for ELISA. The ELISA was performed according to the manufacturer’s instructions. The standard curves were plotted for each experiment.

After fasted for 6 h, whole blood was collected from the posterior vena cava of mice soon after euthanasia. Serum was then obtained after centrifuging the whole blood at 2000 rpm for 10 min at room temperature. Serum insulin levels were measured using an enzyme-linked immunosorbent assay (ELISA) kit (E-EL-M1382c, Elabscience, China) according to the manufacturer's instructions.

Fasting Metabolic Markers in Mice

All mice fasted for 12 h after prior acupuncture. On the second morning, fasting blood glucose (FBG) levels were tested from mouse tails. Mice were then anesthetized with tribromoethanol and blood samples were collected by eye enucleation. Samples were measured by ELISA to detect fasting insulin (FINS) (E-EL-M1382c; Elabscience, Wuhan, China) and Adipo (E-EL-M0002c; Elabscience, Wuhan, China). ELISA was performed according to the manufacturer’s instructions. Additionally, the following formula was used to calculate the homeostasis model assessment estimated insulin resistance (HOMA-IR) = FINS (mU/L) × FBG (mmol/L)/22.5.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
