Última Kaurene diterpene induces apoptosis in U87 human malignant glioblastoma cells by suppression of anti-apoptotic signals and activation of cysteine proteases BJMBR Lizarte Neto,F.S.; Tirapelli,D.P.C.; Ambrosio,S.R.; Tirapelli,C.R.; Oliveira,F.M.; Novais,P.C.; Peria,F.M.; Oliveira,H.F.; Carlotti Junior,C.G.; Tirapelli,L.F.. Gliomas are the most common and malignant primary brain tumors in humans. Studies have shown that classes of kaurene diterpene have anti-tumor activity related to their ability to induce apoptosis. We investigated the response of the human glioblastoma cell line U87 to treatment with ent-kaur-16-en-19-oic acid (kaurenoic acid, KA). We analyzed cell survival and the induction of apoptosis using flow cytometry and annexin V staining. Additionally, the expression of anti-apoptotic (c-FLIP and miR-21) and apoptotic (Fas, caspase-3 and caspase-8) genes was analyzed by relative quantification (real-time PCR) of mRNA levels in U87 cells that were either untreated or treated with KA (30, 50, or 70 µM) for 24, 48, and 72 h. U87 cells treated with KA demonstrated... Tipo: Info:eu-repo/semantics/article Palavras-chave: Kaurenoic acid; Glioblastoma; MiR-21; C-FLIP; Apoptosis. Ano: 2013 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-879X2013000100071 Coupling of palmitate to ovalbumin inhibits the induction of oral tolerance BJMBR Oliveira,F.M.; Silva-Neto,A.F.; Silva,C.A.; Gontijo,C.M.. Oral tolerance is a phenomenon that may occur in animals exposed to protein antigens for the first time by the oral route. They become unable to produce immune responses at the levels normally observed when they are immunized parenterally with antigen in the presence of adjuvants. Lipids have been used as adjuvants for both parenteral and oral immunization. In the present study we coupled ovalbumin with palmitate residues by incubating the protein with the N-hydroxysuccinimide palmitate ester and tested the preparation for its ability to induce oral tolerance. This was performed by giving 20 mg of antigen to mice by the oral route 7 days prior to parenteral immunization in the presence of Al(OH)3. Mice were bled one week after receiving a booster that was... Tipo: Info:eu-repo/semantics/other Palavras-chave: Oral tolerance; Lipid-protein conjugates; Antigen absorption; Gut mucosa; Ovalbumin.
