ABSTRACT
Abstract Introduction: The goal of this study is to investigate the association between diagnosis and severity of coronary artery disease (CAD) and Asprosin level. Methods: Patients diagnosed with CAD who underwent conventional coronary angiography for the first time were included in the present study. The patients were divided into four groups, each consisting of 20 individuals, as medical group, single coronary lesion group, double coronary lesion group, and multiple coronary lesions group. Serum Asprosin values and Gensini scores of the groups were compared in terms of compliance. Results: In this study, Asprosin values were found to be significantly higher in the multiple coronary lesions group than in the medical, single coronary, and double coronary lesion groups (P<0.05). In the double coronary lesion group, Asprosin values were significantly higher (P<0.05) than the in the medical and single coronary lesion groups. It was also found that Asprosin values did not differ at significant levels in the medical and single coronary lesion groups (P>0.05). It was determined that the increases in Asprosin values and Gensini scores were compatible with each other. Conclusion: The present study showed that the increases in serum Asprosin levels, along with the increases in the number of coronary arteries with critical stenosis, might be a marker in diagnosing and determining the severity of CAD.
ABSTRACT
Asprosin is a newly discovered fasting-induced glucogenic adipokine, which is involved in regulating appetite, glucose and fat metabolism and oxidative stress. Recently, it has been found that asprosin is related to metabolic diseases such as type 2 diabetes, obesity, nonalcoholic fatty liver, polycystic ovary syndrome, and cardiovascular diseases such as coronary heart disease and dilated cardiomyopathy, and plays an active role in heart protection. In this paper, the related research progress is summarized.
ABSTRACT
Objective: We hypothesized that asprosin might be increased during pregnancy and gestational diabetes (GD) suggesting a potential role in food intake stimulation during pregnancy and suggesting a role in prediction of GD so, we analyzed changes in plasma asprosin levels in pregnant and non-pregnant rats with and without gestational diabetes. Methods: 40 female rats divided into 4 groups; control non-pregnant, normal pregnant, untreated GD and insulin-treated GD groups. In all groups, body weights (BW), body length, body mass index (BMI) and food intake, levels of asprosin, estrogen, progesterone, serum levels of insulin, glucose and lipid profile were measured. HOMAIR and HOMA-B were calculated. Results: Asprosin levels were found higher in pregnant, GDM and insulin-treated groups in comparison with control group (p ≤ 0.001, p ≤ 0.0001 and p ≤ 0.0001 respectively). Asprosin levels were higher in GDM group during early and late pregnancy in comparison with the pregnant group (p ≤ 0.0001). Asprosin levels decreased in insulin-treated group compared with GDM group (p ≤ 0.0001). Asprosin levels correlated positively with body weight (r=0.821, p<0.05), body mass index (p<0.05), food intake, serum glucose (r=0.9958, p<0.00001), HOMA-IR, cholesterol, triglycerides, LDL-c and VLDL and negatively correlated to HOMA-B, HDL, estradiol and progesterone levels. Conclusion: asprosin levels were significantly elevated during normal pregnancy suggesting that asprosin may have a physiological role during pregnancy as it may participate in stimulation of appetite and food intake commonly occurring during pregnancy. GD rats were found to have significant higher asprosin compared to pregnant group. Asprosin may be a potential factor predicting diabetes mellitus during pregnancy.
ABSTRACT
OBJECTIVE@#To study the effects of high-fat (HF) diet and exercise on the expressions of asprosin and CTRP6 in adipose tissues in different regions of rats during mid-gestation.@*METHODS@#Pregnant SD rats were fed on a standard chow diet or a high-fat (60% fat content) diet for 14 days starting on gestation day (GD) 1. Starting from GD3, the rats fed either on normal or high-fat diet in the exercise groups (CH-RW and HF-RW groups) were allowed access to the running wheels for voluntary running, and those in sedentary groups (CH-SD and HF-SD groups) remained sedentary. At the end of the 14 days, adipose tissues were sampled from different regions of the rats for detecting the mRNA and protein expressions of asprosin and CTRP6 using RT-qPCR and Western blotting.@*RESULTS@#The mRNA expression of asprosin in retroperitoneal adipose tissues was significantly higher in HF-RW group than in the other 3 groups (@*CONCLUSIONS@#High-fat diet and exercise during mid-gedtation can affect the expression levels of asprosin and CTRP6 in adipose tissues of rats in a site-specific manner.

Objective To purify asprosin protein expressed in Escherichia coli expression system and to study its effect on cardiac function.Methods Coding sequence of asprosin was obtained from GenBank.Codon optimization was performed according to the codon preference of E.coli.After gene synthesized, recombinant plasmid was made.Asprosin was then induced and purified by Ni-affinity purification.The mouse model of impaired cardiac function was established by ligating and relaxing the left anterior descending coronary artery.30 mice were randomly divided into 3 groups: sham operation group (sham), cardiac dysfunction group (MI/R) and cardiac dysfunction plus injection of recombinant asposin protein group (MI/R+rAsp).The left ventricular function was detected by echocardiography to determine the improving effect of recombinant asprosin protein on cardiac function.Results After prokaryotic expression and purification, the purity of the target protein was higher than 95%, and the endotoxin content was less than <0.1 EU/μg protein, which was suitable for cell and animal studies.After the recombinant asprosin protein was given, the left ventricular function of the mice was improved significantly (P<0.05).Conclusions Asprosin acts as a myocardial protective molecule to improve cardiac function.
