1. Effect of Arrabidaea chica extract against chemically induced breast cancer in animal model
Abstract Purpose: To examine the effects of Arrabidaa chica (Bignoniacea) extract, a native plant of the Amazon known as crajiru, on a 7,12-dimethyl-1,2-benzanthracene (DMBA)-induced breast cancer model in Wistar rats. Methods: We compared the response of breast cancer to the oral administration of A. chica extract (ACE) for 16 weeks, associated or not wit

2. Angiogênese, células-tronco neoplásicas CD34+ e sinvastatina em modelo de carcinogênese mamária induzida quimicamente / Angiogenesis, CD34+ cancer stem-cells and simvastatin in a chemically induced mammary carcinogenesis model
Breast cancer is the most common malignancy and the leading cause of death from cancer among females worldwide. Despite all the research and all the progress achieved so far, the morbidity and mortality due to this cancer remains high in patients at advanced stages. Recently, it was described a new model of carcinogenesis in which stem cells (SC) could be re

3. Morphological, histological and molecular effects of SERMs tamoxifen and raloxifene in primary prevention of chemically-induced mammary tumors in rats / Efeitos morfológicos, histológicos e moleculares dos moduladores seletivos dos receptores de estrogênios tamoxifeno e raloxifeno na prevenção primária de tumores mamários quimicamente induzidos em ratas
O câncer de mama é a neoplasia mais comum na população feminina, representando até um terço dos novos diagnósticos de neoplasia nessa população em algumas regiões do mundo. A prevenção primária ou secundária constitui a pedra fundamental no controle do câncer de mama; depende da identificação dos determinantes da doença, em termos de inicia

4. Stat3 is required for the development of skin cancer
Signal transducer and activator of transcription 3 (Stat3) is a transcription factor that is constitutively activated in a variety of human malignancies, including prostate, lung, brain, breast, and squamous cell carcinomas. Inhibition of activated Stat3 leads to decreased proliferation and apoptosis of many cancer-derived cell lines, while the introduction

5. A simple and cost-effective method for producing small interfering RNAs with high efficacy
Small interfering RNAs (siRNAs) are powerful RNA interference (RNAi) reagents for directed post- transcriptional gene silencing. Exogenous siRNA is frequently used in RNAi studies. However, due to profound differences in the activity of siRNAs targeted to different regions of a gene, several reagents may have to be screened for optimal activity. This approac

6. Metabolism of benzo[a]pyrene by human mammary epithelial cells: toxicity and DNA adduct formation.
Pure cultures of human breast epithelial cells and of fibroblastic cells in early passage provided the opportunity to ask whether either cell type had the capability for metabolizing chemical carcinogens and, if so, was the fate of the metabolic products compatible with chemical carcinogens being a factor in the initiation of breast cancer in women. For this
