1. Chemical Constituents, Antiproliferative and Antioxidant Activities of Vernonanthura nudiflora (Less.) H. Rob. Aerial Parts
Sesquiterpene lactones are an important class of secondary metabolites frequently isolated from Vernonanthura genus that present a variety of biological properties, including antiproliferative activity. Due to the limitation of pharmacological studies on Vernonanthura nudiflora, the aim of this work was to investigate their antioxidant potential and antiprol

2. 4-Nerolidylcatechol induces autophagy in human glioblastoma cells
ABSTRACT Gliomas account for the majority of primary malignant brain tumors and present invasive behavior into adjacent healthy tissue. While 4-NC had previously shown to induce apoptotic cell death in a melanoma model, for the glioma model described in this paper 4-NC is cytotoxic for the cells with the induction of the autophagic pathway. Trypan blue exclu

5. The prevalence of human cytomegalovirus DNA in gliomas of Brazilian patients
Members of the Herpesviridae family have been implicated in a number of tumours in humans. At least 75% of the human population has had contact with cytomegalovirus (HCMV). In this work, we screened 75 Brazilian glioma biopsies for the presence of HCMV DNA sequences. HCMV DNA was detected in 36% (27/75) of the biopsies. It is possible that HCMV could be a co

6. Chemical composition and cytotoxicity activity of the essential oil of Pterodon emarginatus
Pterodon emarginatus Vogel, Fabaceae, is a native aromatic tree distributed by central region of Brazil. Hydroalcoholic infusions of the seeds are used in folk medicine for their anti-rheumatic and anti-inflammatory properties. The objective of this work was identified the chemical components and verify the cytotoxic effect of the essential oil (EO) from P.

8. Análise do papel da prostaglandina E2 na proliferação, migração e apoptose na linhagem de glioma humano T98G e o efeito do ácido gama-linolênico e ibuprofeno sobre este prostanóide. / Analysis of the role of prostaglandin E2 on proliferation, migration and apoptosis in the T98G human glioma cell line and the effects of gamma - linolenic acid and Ibuprofen on this prostanoid.
Gliomas são tumores do sistema nervoso central e o glioblastoma multiforme (GBM) é sua forma mais comum e de pior prognóstico. A proliferação desordenada, migração estão entre os processos biológicos que conferem ao GBM um comportamento altamente agressivo. O objetivo deste estudo foi analisar in vitro o papel de PGE2 na proliferação, migração e

9. Atividade anticâncer in vitro e in vivo de Psidium guajava L. (nome popular: goiabeira) / Psidium guajava L. (popular name guava) in vitro and in vivo anticancer activity
Anticancer drug research based on screening of natural sources enabled the discovery of several drugs that are used in cancer treatment. This project aimed to evaluate the in vitro and in vivo anticancer activity of Psidium guajava L. (popular name: guava), elected for its ethnopharmacological use for antiparasitic activity. After harvesting, the vegetal mat

11. Chemical composition and cytotoxic activity of the essential oil from the leaves of Casearia lasiophylla
The essential oil obtained by hydrodistillation from fresh leaves of Casearia lasiophylla Eichler, Salicaceae, was analyzed by gas capillary (GC/FID and GC/MS). The cytotoxicity of the leaves essential oil was tested in vitro againstU251 (glioma), UACC-62 (melanoma), MCF-7 (breast), NC1-ADR/RES (ovarian-resistant), NCI-H460 (lung), PC03 (prostate), OVCAR-3 (

12. A sinalização parácrina da triiodotironina derivada das células gliais ativa a expressão de genes neuronais no cérebro de roedores e em células humanas / A paracrine signaling of triiodothyronine derived from glial cells activates the expression of neuronal genes in brain of rodents and in human cells
O hipotiroidismo nos humanos caracteriza-se por distúrbios neurológicos graves, frequentemente irreversíveis, que ressaltam o papel crítico dos hormônios tiroidianos (HT) no cérebro. Apesar disto, pouco se sabe sobre as vias de sinalização que controlam a ação dos HT no cérebro. O que é conhecido é que a tiroxina (T4), um pró-hormônio, é conv
