Influência da adição de fator de crescimento fibroblástico 10 (FGF10), durante a maturação oocitária, na produção in vitro de embriões bovinos

The Brazilian livestock stands out for having the world largest commercial herd of cattle and leads meat exportation and production of bovine embryos. The in vitro production (IVP) of embryos is considered an effective option to overcome problems such as infertility in cows with high economic value and also for genetic improvement of cattle. The in vitro oocyte maturation is an essential step to the success of IVP, but is still considered poor when compared to in vivo maturation. Recent studies have suggeested an important role of Fibroblast Growth Factor 10 (FGF10) on the in vitro maturation of oocytes, which favored the expression of genes related to oocyte maturation and cumulus cell expansion. Aware that maturity stage influences the final production of blastocysts, we aimed study to verify if the addition of FGF10 into the maturation medium is able to affect positively the IVP of bovine embryos. Hence, FGF10 was added to maturation in five different concentrations: 0.5 ng/mL (group 0.5), 2.5 ng/mL (group 2.5), 5 ng/mL (group 5), 10 ng/mL (group 10) and 50 ng/mL (group 50). Additionally, two other maturation groups were used, group BSA (Bovine Serum Albumin, 4 mg/mL) and group FCS (Fetal Calf Serum, 10%). The rates of cleavage, morula and blastocyst were analyzed by Analysis of Variance (ANOVA), differences of P<0.05 were considered significant. Cleavage rates did not differ between the seven groups. On the other hand, morula rate on FCS group was higher than groups BSA, 0.5, 10 and 50 (P<0.05), but did not differ among groups treated with intermediate doses of FGF10 (2.5 and 5). FCS group presented higher blastocyst rate compared to all other groups that were well below the FCS group (P<0.0001). Therefore, the use of FGF10 during oocyte maturation did not affect positively embryo development on the IVP of bovine embryos

Efeitos preventivos do exercício físico sobre as proteínas ciclooxigenase-2 (COX-2) e fator de crescimento de vasos derivado do endotélio (VEGF) no músculo cardíaco em ratos tratados com dexametasona

Dexamethasone (DEXA) is a synthetic glucocorticoid widely used in the handling of several drugs, for its proven benefits in fighting inflammation and allergies. Despite their benefits, their chronic use leads to several side effects that include changes in the body in the metabolism of carbohydrates, lipids and proteins. Moreover, being an anti-inflammatory, acts on the arachidonic acid pathway, reducing the expression of the enzyme cyclooxygenase (COX-2) and growth factor derived from the endothelium of blood vessels (VEGF) in various tissues. However, its effects on the myocardium are still uncertain. The physical training (PT), in turn, promotes effects contrary to those caused by chronic use of DEXA, however, little is known about the preventive effects of TF in the side effects of Dexa in the myocardium. Therefore, the aim of this study was to determine if the TF has the ability to prevent and/or mitigate the effects of Dexa in protein expression of COX-2 and VEGF in the myocardium. Forty animals were divided into 4 groups: sedentary control (SC), sedentary treated with Dexa (SD), trained control (TC) and Trained treated with Dexa (TD) and submitted to a protocol of physical training on the treadmill for 70 days (1 h/day-5 days per week, 60% of physical capacity) or kept sedentary. Over the past 10 days, rats were treated with Dexa (Decadron, 0.5 mg/kg per day, ip) or saline. During training the animals were weighed weekly and during treatment daily. At the end of treatment was made to measure fasting glucose levels of animals. The rats were killed with excess anesthesia and cardiac muscle was removed, weighed, homogenized, centrifuged and stored at -20° C for analysis of protein expression of VEGF and COX-2 by Western blotting technique. Treatment with dexamethasone caused a weight loss of 18% in sedentary animals and 13% in trained as well as elevated levels of fasting glucose in sedentary (88%). The TF was unable to mitigate the loss in...
