Objectives: Menopausal transition with declining estrogen levels significantly affects the physiological properties of women and consequently contributes to a series of medical conditions, including obesity. collagen hydrolysate (2.5 mg/mL) exhibited significant attenuation in body weight gain and adipocyte enlargement ( em P /em 0.05), but insignificant change in uterus weight. Further investigation indicated that collagen hydrolysate supplementation insignificantly affected the levels of dorsal excess fat, serum total cholesterol, and serum triacylglycerol. Levels of serum biochemical factors, calcium, phosphorus, and glucose were also insignificantly altered by collagen hydrolysate supplementation. Conclusion: Collagen hydrolysate supplementation reduced body weight gain and adipocyte enlargement in response to ovariectomy but slightly affected blood lipids, calcium, and glucose in both sham-operated and OVX rats. Collagen AZD4547 small molecule kinase inhibitor hydrolysate supplementation is beneficial in ameliorating estrogen deficiency-induced obesity and its associated risk factors. strong class=”kwd-name” Keywords: Collagen, Unhealthy weight, estrogen deficiency Launch The alter in body composition of post-menopausal females is considered due to long-term interactions AZD4547 small molecule kinase inhibitor among energy intake, energy expenditure, and sex hormonal position or a mixture thereof 1, 2, 3, 4,5. Menopause is generally associated with elevated central (visceral) surplus fat 6,7, accompanied by a growing incidence of hypertension 8 and the AZD4547 small molecule kinase inhibitor aggravation of the lipoprotein profile 9, which result in metabolic syndrome 10 and the next rise in the BMP8B incidence of cardiovascular illnesses 11. During menopausal transition, women knowledge deleterious adjustments in circulating inflammatory markers and adipokines correlated with an increase of visceral adiposity 12. An increasing number of proof provides demonstrated that chronic low-quality/subclinical irritation is an integral aspect in the advancement of atherosclerotic coronary disease and is certainly closely connected with unhealthy weight, insulin level of resistance, and metabolic syndrome 13,14,15,16. Dietary proteins is important in controlling bodyweight, which is certainly partially related to its results on satiety. Among common dietary proteins, purified collagen hydrolysate provides been clinically established as a highly effective appetite retardant that maintains a satiating impact to market weight reduction 17,18. Insoluble fibrous proteins collagen, the one most abundant proteins in animals, may be the major element of the extracellular matrix and connective cells. At least 16 types of collagen have already been determined in human beings; among these, 80%-90% participate in types I, II, and III collagen. Although supplementing with collagens and their derived peptides provides been proven to improve cellulite and epidermis wellness 19, whether collagen hydrolysate supplementation impacts menopause-induced unhealthy weight continues to be unclear. In today’s research, we aimed to research the consequences of collagen hydrolysate supplementation on estrogen deficiency-induced obesity through the use of an ovariectomized (OVX) animal model. Your body fat, uterus weight, fats mass, and serum biochemical AZD4547 small molecule kinase inhibitor elements of OVX rats had been assessed. Adipocyte size was also established. Materials and Strategies Reagents All chemical substances used were attained from Sigma-Aldrich (St. Louis, MO, United states) except when usually specified. Collagen hydrolysate was bought from KVW Wellness Co. Ltd. (Taipei, Taiwan). Ovariectomized rat model All feminine Sprague-Dawley rats weighing around 200 g had been bought from the National Laboratory Pet Center (Taipei City, Taiwan) and managed under the supervision of the Institutional Animal Care and Use Committee (IACUC) of the China Medical University. Animal experiment protocol was approved by the IACUC and performed in accordance with the guidelines. For estrogen deficiency-induced obesity and collagen supplementation, 24 rats were divided into 4 groups for sham operation (group 1) and OVX operation (groups 2-4). Operation was performed under Nembutal (Pentobarbital sodium, 50 mg/kg body weight) anesthesia. Groups 1 and 2 were supplied with sterile water. Groups 3 and 4 were supplied with sterile water containing 1.25 mg/mL and 2.5 mg/mL collagen hydrolysate, respectively. All animals were managed under 12 h/12 h light-dark cycles at controlled heat (22 0.5 AZD4547 small molecule kinase inhibitor oC) and humidity (45%-50%). Body weight was measured daily at a specified time during the experiment. At the end of the experiment, blood and perigonadal adipose tissue were immediately obtained after the animals were sacrificed. The dorsal excess fat and uterus of each rat were dissected and weighed. Histological analysis of adipose tissue and cell size determination The perigonadal adipose tissues were fixed in zinc formaldehyde overnight at 4 C and transferred into phosphate-buffered saline. The fixed tissues were then embedded into paraffin, sectioned, and stained with hematoxylin and eosin. Digital images were captured at 200 magnitude using an Olympus DX51 light microscope (Tokyo, Japan). Measurement of serum biochemical makers The blood was coagulated by maintaining it at room temperature for 15-20 min, followed by centrifugation for 10 min. The indicated parameters (calcium ions, glucose, inorganic phosphorus, total cholesterol, and triacylglycerol) were measured using a serum biochemistry analyzer (AU400, Olympus, Tokyo, Japan). Statistical analysis Data were expressed as means standard error. Statistical comparisons were made via ANOVA test using a statistical software (SigmaStat 3.5, Systat Software, Inc.
