GPC3 reduces cell proliferation in renal carcinoma cell lines

Background: Glypican 3 (GPC3) is a member of the family of glypican heparan sulfate proteoglycans (HSPGs). The GPC3 gene may play a role in controlling cell migration, negatively regulating cell growth and inducing apoptosis. GPC3 is downregulated in several cancers, which can result in uncontrolled cell growth and can also contribute to the malignant phenotype of some tumors. The purpose of this study was to analyze the mechanism of action of the GPC3 gene in clear cell renal cell carcinoma.Methods: Five clear cell renal cell carcinoma cell lines and carcinoma samples were used to analyze GPC3 mRNA expression (qRT-PCR). Then, representative cell lines, one primary renal carcinoma (786-O) and one metastatic renal carcinoma (ACHN), were chosen to carry out functional studies. We constructed a GPC3 expression vector and transfected the renal carcinoma cell lines, 786-O and ACHN. GPC3 overexpression was analyzed using qRT-PCR and immunocytochemistry. We evaluated cell proliferation using MTT and colony formation assays. Flow cytometry was used to evaluate apoptosis and perform cell cycle analyses.Results: We observed that GPC3 is downregulated in clear cell renal cell carcinoma samples and cell lines compared with normal renal samples. GPC3 mRNA expression and protein levels in 786-O and ACHN cell lines increased after transfection with the GPC3 expression construct, and the cell proliferation rate decreased in both cell lines following overexpression of GPC3. Further, apoptosis was not induced in the renal cell carcinoma cell lines overexpressing GPC3, and there was an increase in the cell population during the G1 phase in the cell cycle.Conclusion: We suggest that the GPC3 gene reduces the rate of cell proliferation through cell cycle arrest during the G1 phase in renal cell carcinoma.

Moderate Exercise Reduces Food Consumption in Obese Mice for Activate Jak-2/Stat-3 Pathway in the Hypothalami

It is very known that due to inflammatory processes the obesity leads to resistance to leptin, it reduces phosphorylation via JAK-2/STAT-3, which generates lower STAT-3 activity in the cell nucleus, and it leads to decrease the number of transcription of anorexigenic neurons (POMC/CART) and allowing transcription of orexigenic (NPY/AgRP). PURPOSE: The present study aimed to evaluate the effects of moderate aerobic training on food intake of obese mice through analysis of activity of hypothalamic proteins JAK-2/STAT-3. METHODS: It were used 30 Swiss mice (30 days old) divided into 3 groups: Control Group (C): sedentary animals fed with balanced diet ; Obese (OB) sedentary animals fed with high-fat diet throughout the experiment and Trained Obese (TOB) : animals fed with high fat diet throughout the experiment , kept sedentary during the first half of the experiment (8 weeks) and submitted to physical training protocol during the second half of the experiment (8 weeks). The exercise program consisted of treadmill running 1h, 5 days/week during 8 weeks at a speed equivalent to 60 % of maximum potency determined at the beginning of training period. To assess the leptin resistance, after rats were deprived of food for 6h with free access to water, they received i.p injection with leptin (2.0µl, 10-6M), after this, the chow was returned and food intake was determined by measuring the quantity and Kcal consumed at the end of 2h. The hypothalami was removed for determination of JAK-2 and STAt-3 activity. RESULTS: Our results showed that moderate physical exercise was effective in improving the JAK/STAT signaling pathway in the hypothalamus of obese animals. This has made these obese animals had reduced food intake and consequently lower body mass gain. CONCLUSION: It can be concluded that physical exercise, for restoring leptin signaling in the hypothalamus, controls the synthesis of neurons responsible for appetite and thus is an important tool in the treatment of obesity.

Efeitos do aparelho de Herbst no tratamento proecoce da má oclusão classe II de Angle

Due to its high prevalence in general population, Angle Class II malocclusion has been widely studied by several authors, as well as the methods for its treatment. Among the possible treatment methods stands out the Herbst appliance. Reintroduced more than three decades ago in the orthodontics community, it became the most utilized appliance because it does not require patient compliance, and provides continued action through bilateral telescopic tubes. The objective of the present article was to demonstrate the early treatment of Class II Division 1 malocclusion with mandibular retrusion using Herbst appliance.
