1. Relação da imunoexpressão da bmp-2, bmpr-ia e bmpr-ii com o perfil clínico-patológico em carcinoma epidermóide de lábio inferior
Atualmente as proteínas morfogenéticas do osso (BMPs) têm efetiva participação no crescimento de neoplasias malignas. Sabendo que são escassos os trabalhos envolvendo BMPs e o carcinoma epidermóide oral, este trabalho realizou um estudo imunoistoquímico da BMP-2, BMPR IA e BMPR II em carcinomas epidermóides (CE) de lábio inferior relacionando com o

2. Estudo clínico-patológico do carcinoma epidermóide de língua e imunoistoquímico das proteínas BMP-2, BMPR-IA, BMPR-II e endoglina
As BMPs (proteínas morfogenéticas ósseas) são citocinas relacionadas com a proliferação e angiogênese em diversos tipos de câncer humano. Com este trabalho foi analisada a expressão imunoistoquímica das proteínas BMP-2, BMPR-IA, BMPR-II e endoglina (CD105), correlacionando-a com o comportamento biológico e a angiogênese local nos carcinomas epid

3. Avaliação da expressão da BMP -2/4 e BMPR-IA em Carcinoma Epidermóide Oral metastático e não metastático
A expressão das proteínas morfogenéticas ósseas (BMPs) está alterada em vários cânceres humanos. A BMP-2/4 e o BMPR-IA foram recentemente encontrados superexpressos em lesões malignas e pré-malignas de alto risco em epitélio oral. Este estudo analisou a expressão da BMP-2/4 e seu receptor BMPR-IA em 23 espécimes de Carcinoma Epidermóide Oral (CE

4. Sequential actions of BMP receptors control neural precursor cell production and fate
Bone morphogenetic proteins (BMPs) have diverse and sometimes paradoxical effects during embryonic development. To determine the mechanisms underlying BMP actions, we analyzed the expression and function of two BMP receptors, BMPR-IA and BMPR-IB, in neural precursor cells in vitro and in vivo. Neural precursor cells always express Bmpr-1a, but Bmpr-1b is not

5. Distinct roles of type I bone morphogenetic protein receptors in the formation and differentiation of cartilage
The bone morphogenetic proteins (BMPs), TGFβ superfamily members, play diverse roles in embryogenesis, but how the BMPs exert their action is unclear and how different BMP receptors (BMPRs) contribute to this process is not known. Here we demonstrate that the two type I BMPRs, BMPR-IA and BMPR-IB, regulate distinct processes during chick limb development. B

6. BMP-2 antagonists emerge from alterations in the low-affinity binding epitope for receptor BMPR-II
Bone morphogenetic protein-2 (BMP-2) induces bone formation and regeneration in adult vertebrates and regulates important developmental processes in all animals. BMP-2 is a homodimeric cysteine knot protein that, as a member of the transforming growth factor-β (TGF-β) superfamily, signals by oligomerizing type I and type II receptor serine-kinases in the

7. Human type II receptor for bone morphogenic proteins (BMPs): extension of the two-kinase receptor model to the BMPs.
Bone morphogenic proteins (BMPs) are universal regulators of animal development. We report the identification and cloning of the BMP type II receptor (BMPR-II), a missing component of this receptor system in vertebrates. BMPR-II is a transmembrane serine/threonine kinase that binds BMP-2 and BMP-7 in association with multiple type I receptors, including BMPR

8. Roles of Bone Morphogenetic Protein Type I Receptors and Smad Proteins in Osteoblast and Chondroblast Differentiation
The biological effects of type I serine/threonine kinase receptors and Smad proteins were examined using an adenovirus-based vector system. Constitutively active forms of bone morphogenetic protein (BMP) type I receptors (BMPR-IA and BMPR-IB; BMPR-I group) and those of activin receptor–like kinase (ALK)-1 and ALK-2 (ALK-1 group) induced alkaline phosphatas

9. Outflow tract cushions perform a critical valve-like function in the early embryonic heart requiring BMPRIA-mediated signaling in cardiac neural crest
Neural crest-specific ablation of BMP type IA receptor (BMPRIA) causes embryonic lethality by embryonic day (E) 12.5, and this was previously postulated to arise from a myocardial defect related to signaling by a small population of cardiac neural crest cells (cNCC) in the epicardium. However, as BMP signaling via cNCC is also required for proper development

10. The spatiotemporal expression pattern of the bone morphogenetic protein family in rat ovary cell types during the estrous cycle
In the mammalian ovary, great interest in the expression and function of the bone morphogenetic protein (BMP) family has been recently generated from evidence of their critical role in determining folliculogenesis and female fertility. Despite extensive work, there is a need to understand the cellular sites of expression of these important regulatory molecul
