1. Smooth muscle cell behavior of rat ventral prostate after androgen deprivation in vivo and mechanical stretch assay in vitro / Comportamento da celula muscular lisa da prostata ventral de ratos apos privação androgenica in vivo e sob estiramento mecanico in vitro
Smooth muscle cells (SMC) are the main component of the prostatic stroma and play important roles in the organ physiology, acting on the contraction associated with ejaculation and on the remodeling related to neoplasias or androgen deprivation, on the production of paracrine factors and the synthesis/degradation/reorganization of extracellular matrix compon

2. Reposição hormonal na prostata ventral de ratos castrados : recuperação glandular, reorganização estremal e atividade de metaloproteinases de matriz
The ventral prostate (VP) and the seminal vesic1e (SV) are both androgen dependents, in which undergoe atrophy and regrowth processes afier androgen deprivation and reposition. In both events, it was observed alterations in the epithelium as well as in the stromal compartiments. The aspects related to the prostate epithelium induced by testosterone replaceme

3. Efeito inibidor da finasterida sobre a enzima 5-alfa-redutase na prostata de gerbilos adultos (Meriones unguiculatus)
Prostatic deve1opment and differentiatíon are induced by androgens acting via mesenchymal-epithelial interactions, and during adult life the gland is maintained functionally active by reciprocal homeostatic stromal-epithelial interactions. Hormonal alterations, usually associated with the physical aspects of aging, leads to disruptions of this homeostatic i

4. Mononuclear cells from umbilical cord blood and from granulocyte colony-stimulating factor (G-CSF) mobilized peripheral blood. Analysis of proliferation and apoptosis in vitro / "Células mononucleares de sangue de cordão umbilical e de sangue periférico estimulado com fator de crescimento granulocítico (G-CSF) : análise da proliferação e de apoptose in vitro"
Células mononucleares de sangue de cordão umbilical (SCU) e sangue periférico mobilizado (SPM) com G-CSF, foram cultivadas in vitro com citocinas, na presença ou não de estroma de medula óssea. Os objetivos foram avaliar a capacidade proliferativa de células progenitoras, a ocorrência de apoptose e expressão de integrina. Nas culturas sem estroma, a

5. Cell-type-specific expression of rat steroid 5 alpha-reductase isozymes.
The enzyme steroid 5 alpha-reductase (EC 1.3.99.5) is a component of an intercellular signaling pathway that determines cell fate in the primordium of the mammalian reproductive tract. During male phenotypic sexual differentiation, the dihydrotestosterone product of this enzyme binds to the androgen receptor and initiates development of the external genitali

6. Tissue factor gene expression in the adipose tissues of obese mice
Altered expression of proteins of the fibrinolytic and coagulation cascades in obesity may contribute to the cardiovascular risk associated with this condition. We previously reported that plasminogen activator inhibitor 1 (PAI-1) is dramatically up-regulated in the plasma and adipose tissues of genetically obese mice. This change may disturb normal hemostat
