1. Molecular mechanism of benign biliary stricture inhibition by rosiglitazone-activated peroxisome proliferator-activated receptor gamma
SUMMARY OBJECTIVE: The aim of this study was to investigate whether rosiglitazone-activated peroxisome proliferator-activated receptor gamma can inhibit the occurrence of benign biliary stricture and further elucidate the relevant molecular signaling mechanism. METHODS: The primary cultured rat biliary fibroblasts following experiments were performed using

2. The role of KDR in intrauterine adhesions may involve the TGF-β1/Smads signaling pathway
The aim of this study was to investigate the role of kinase-insert domain-containing receptor (KDR) in intrauterine adhesions (IUA) and its mechanism. The Case group consisted of 92 patients diagnosed with IUA, and the Control group included 86 patients with uterine septum who had normal endometrium verified with an uteroscope. In addition, 50 rats were rand

3. Retinoic acid increases the effect of bone morphogenetic protein type 2 on osteogenic differentiation of human adipose-derived stem cells
Abstract Bone morphogenetic protein type 2 (BMP-2) and retinoic acid (RA) are osteoinductive factors that stimulate endogenous mechanisms of bone repair which can be applied on management of osseous defects in oral and maxillofacial fields. Objective Considering the different results of RA on osteogenesis and its possible use to substitute/potency BMP-2 ef

4. MicroRNA-221 promotes cell proliferation, migration, and differentiation by regulation of ZFPM2 in osteoblasts
Bone fracture is a common medical condition, which may occur due to traumatic injury or disease-related conditions. Evidence suggests that microRNAs (miRNAs) can regulate osteoblast differentiation and function. In this study, we explored the effects and mechanism of miR-221 on the growth and migration of osteoblasts using MC3T3-E1 cells. The expression leve

5. Galunisertib (LY2157299), a transforming growth factor-β receptor I kinase inhibitor, attenuates acute pancreatitis in rats
Galunisertib (LY2157299), a selective ATP-mimetic inhibitor of TGF-β receptor I (TGF-βRI), is the only known TGF-β pathway inhibitor. In the present study, we investigated the effect of galunisertib on taurocholate (TAC)-induced acute pancreatitis (AP) in rats, and the role of TGF-β and NF-κB signaling pathways. AP was induced by infusion of TAC into th

6. Eventos moleculares associados ao aumento gengival induzido por ciclosporina A são atenuados pela superexpressão de Smad7 / Molecular events associated with cyclosporin A induced gingival overgrowth are attenuated by Smad 7 overexpression
O aumento gengival induzido por ciclosporina A (CsA) é causado por um acúmulo excessivo de matriz extracelular, resultado da ação do fator de crescimento transformante-beta 1 (TGF-ß1) sobre a atividade dos fibroblastos gengivais. O presente estudo investigou in vitro os efeitos da superexpressão de Smad7, um inibidor da sinalização de TGF-ß1, nos ev

7. O EFEITO DO LASER DE BAIXA INTENSIDADE NA FIBROSE INTERSTICIAL RENAL
Justificativa e Objetivo: Independente da etiologia, a doença renal crônica (DRC) envolve fibrose generalizada e progressiva do tecido, atrofia tubular e a perda da função renal. Atualmente, as terapias eficazes para esta condição são escassas. Neste estudo, foram investigados os efeitos da terapia laser de baixa intensidade (LLLT) sobre a fibrose int

8. Transforming growth factor-β in graft vessels: histology and immunohistochemistry
OBJECTIVES: The biological functions of transforming growth factor-β signaling that involves Smad proteins have not been previously investigated with respect to coronary artery bypass grafts. The aim of the present study was to observe the immunostaining of proteins that are related to this signaling pathway. METHODS: Fifteen remnants of coronary artery byp

9. O efeito das proteínas morfogenéticas ósseas (BMPs) associadas a osso esponjoso autógeno na reparação de falhas experimentais na calota craniana de coelho (Oryctolagus cuniculus) / The effect of the Bone morphogenetic protein (BMPs) associated with cancelous autogenous bone graft in the reparation of calvarial experimental rabbits defects (Oryctolagus cuniculus)
As proteínas morfogenéticas ósseas (BMPs) são promotores de crescimento capazes de induzir a formação de osso e cartilagem, promovendo a quimiotaxia e diferenciação de células mesenquimais para o local onde foram implantadas, mas para uma efetiva osteocondução necessitam de uma substância carreadora. Quando implantadas em tecidos animais, as BMPs

10. CHIP Mediates Degradation of Smad Proteins and Potentially Regulates Smad-Induced Transcription
Transforming growth factor beta (TGF-β)/bone morphogenetic protein (BMP) family ligands interact with specific membrane receptor complexes that have serine/threonine kinase activities. The receptor phosphorylation and activation induced by the ligands leads to phosphorylation of the Smad proteins, which translocate to the nucleus, controlling gene expressio

11. CREB binding protein is a required coactivator for Smad-dependent, transforming growth factor β transcriptional responses in endothelial cells
The transforming growth factor-β (TGF-β) superfamily of growth factors and cytokines has been implicated in a variety of physiological and developmental processes within the cardiovascular system. Smad proteins are a recently described family of intracellular signaling proteins that transduce signals in response to TGF-β superfamily ligands. We demonstrat

12. Repression of Smad transcriptional activity by PIASy, an inhibitor of activated STAT
Smad proteins mediate transforming growth factor β (TGF-β)-inducible transcriptional responses. Protein inhibitor of activated signal transducer and activator of transcription (PIAS) represents a family of proteins that inhibits signal transducer and activator of transcription and also regulates other transcriptional responses. In an effort to identif
