1. Transcriptional profiling of uterine leiomyoma rats treated by a traditional herb pair, Curcumae rhizoma and Sparganii rhizoma
The aim of this study was to elucidate the concise effects of a traditional herb pair, Curcumae rhizoma-Sparganii rhizoma (CRSR), on uterine leiomyoma (UL) by analyzing transcriptional profiling. The UL rat model was made by intramuscular injection of progesterone and gavage administration of diethylstilbestrol. From 11 weeks of the establishment of the mode

2. Carcinoma ex-adenoma pleomórfico derivado de adenoma pleomórfico recorrente mostra diferença importante por array CGH em comparação com adenoma pleomórfico recorrente sem transformação maligna
Resumo Introdução: Uma etapa fundamental do desenvolvimento do câncer é o acúmulo progressivo de alterações genômicas, resultando na ruptura de vários mecanismos biológicos. Carcinoma ex-adenoma pleomórfico (CXAP) é uma neoplasia agressiva que surge a partir de um adenoma pleomórfico. O CXAP derivado de um AP recorrente (APR) foi raramente rela

3. Atrial Fibrillation, Neurocognitive Decline and Gene Expression After Cardiopulmonary Bypass
ABSTRACT OBJECTIVE: Atrial fibrillation and neurocognitive decline are common complications after cardiopulmonary bypass. By utilizing genomic microarrays we investigate whether gene expression is associated with postoperative atrial fibrillation and neurocognitive decline. METHODS: Twenty one cardiac surgery patients were prospectively matched and under

5. Análise cromossômica por microarray em crianças com deficiências de desenvolvimento e anomalias congênitas
OBJETIVO: O uso clínico de técnicas baseadas em microarrays para a análise de transtornos de desenvolvimento tem surgido durante a última década. Assim, o microarray cromossômico tem sido posicionado como um teste de primeiro nível clínico. Relatamos a primeira experiência em uma coorte chilena. MÉTODOS: Pacientes chilenos com atraso de desenvolvi

6. Transcriptional profile of fibroblasts obtained from the primary site, lymph node and bone marrow of breast cancer patients
Cancer-associated fibroblasts (CAF) influence tumor development at primary as well as in metastatic sites, but there have been no direct comparisons of the transcriptional profiles of stromal cells from different tumor sites. In this study, we used customized cDNA microarrays to compare the gene expression profile of stromal cells from primary tumor (CAF, n

7. Leptin and leptin receptor expressions in prostate tumors may predict disease aggressiveness?
PURPOSE: The aim of this study was to evaluate the expression of leptin and its receptor in histological sections of prostate tumors, and their association with prognostic factors. METHODS: A total of 532 surgical specimens from prostate cancer were studied. After histopathological diagnosis, the samples were included in tissue microarrays containing cores

8. Whole transcriptome organisation in the dehydrated supraoptic nucleus
The supraoptic nucleus (SON) is part of the central osmotic circuitry that synthesises the hormone vasopressin (Avp) and transports it to terminals in the posterior lobe of the pituitary. Following osmotic stress such as dehydration, this tissue undergoes morphological, electrical and transcriptional changes to facilitate the appropriate regulation and relea

9. Evaluation of Bcl-2, Bcl-x and Cleaved Caspase-3 in Malignant Peripheral Nerve Sheath Tumors and Neurofibromas
OBJETIVOS: Estudar a expressão das proteínas Bcl-2, Bcl-x, assim como a presença da caspase-3 clivada em neurofibromas e tumores malignos da bainha do nervo periférico. A expressão de Bcl-2 e Bcl-x e a presença da caspases-3 clivada foram comparadas com as características clinicopatológicas dos tumores malignos da bainha do nervo periférico e seu im

10. Basal cytokeratin as a potential marker of low risk of invasion in ductal carcinoma in situ
OBJECTIVES: Biological markers that predict the development of invasive breast cancer are needed to improve personalized therapy for patients diagnosed with ductal carcinoma in situ. We investigated the role of basal cytokeratin 5/6 in the risk of invasion in breast ductal carcinoma in situ. METHODS: We constructed tissue microarrays using 236 ductal carc

12. ImunoexpressÃo de metaloproteinases 2 e 14 e do inibidor TIMP-2 no cÃncer colorretal / Immunoexpression of metalloproteinases 2 and 14 and the inhibitor TIMP-2 in colorectal cancer
O cÃncer colorretal(CCR) Ã altamente prevalente nos paÃses mais ricos e industrializados. As metaloproteinases de matriz (MMPs) sÃo importantes enzimas que facilitam a invasÃo e disseminaÃÃo do tumor em vÃrios tipos de cÃncer, inclusive o colorretal. Os inibidores teciduais de metaloproteinases (TIMPs) sÃo os principais inativadores fisiolÃgicos d
