Lung cancer is the most common visceral malignancy in males, with rapidly increasing incidence in females, and a devastatingly poor prognosis. Transforming growth factor (TGF)-beta has been shown to induce senescence in A549 lung cancer cells, and both TGF-beta and bone morphogenetic protein (BMP) 2 can suppress the transformed phenotype of A549 cells in vitro. We examined the effects of BMP4, ...
In the normal mouse embryo, Bmp4 is expressed in mesenchymal cells surrounding the Wolffian duct (WD) and ureter stalk, whereas bone morphogenetic protein (BMP) type I receptor genes are transcribed either ubiquitously (Alk3) or exclusively in the WD and ureter epithelium (Alk6). Bmp4 heterozygous null mutant mice display, with high penetrance, abnormalities that mimic human congenital anomalie...
The Crim1 gene is predicted to encode a transmembrane protein containing six von Willebrand-like cysteine-rich repeats (CRRs) similar to those in the BMP-binding antagonist Chordin (Chrd). In this study, we verify that CRIM1 is a glycosylated, Type I transmembrane protein and demonstrate that the extracellular CRR-containing domain can also be secreted, presumably via processing at the membrane...
BACKGROUND The Bone Morphogenetic Protein 4 gene (BMP4) is located in chromosome 14q22-q23 which has shown evidence of linkage for isolated nonsyndromic cleft lip with or without cleft palate (NSCL/P) in a genome wide linkage analysis of human multiplex families. BMP4 has been shown to play crucial roles in lip and palatal development in animal models. Several candidate gene association analyse...
objective(s):mesenchymal stem cells (mscs) derived from wharton’s jelly (wj-mscs) are now much more appealing for cell-based infertility therapy. hence, wj-mscs differentiation toward germ layer cells for cell therapy purposes is currently under intensive study. materials and methods: mscs were isolated from human wharton’s jelly and treated with bmp4, retinoic acid (ra) or co-cultured on human...
25 There are 2 different types of fat present in mammals: white adipose tissue, the primary site of 26 energy storage, and brown adipose tissue, which is specialized in energy expenditure. Factors 27 that specify the developmental fate and function of brown fat are poorly understood. Bone 28 morphogenic proteins (BMPs) play an important role in adipogenesis. While BMP4 is capable of 29 triggeri...
In response to acute damage, Müller glia in the chicken retina have been shown to be a source of proliferating progenitor-like cells. The secreted factors and signaling pathways that regulate this process remain unknown. The purpose of this study was to test whether secreted factors, which are known to promote glial differentiation during development, regulate the ability of Müller glia to prol...
AIM To investigate the influence of bone morphogenetic protein type IA receptor [BMPR-IA (ALK3)] conditional knockout in lens on expression of bone morphogenetic protein 4 (BMP4) in lens during the development of the vertebrate eye. METHODS Cre-positive mice were mated with Cre-negative mice to generate 50% Cre-positive (conditional knockout, CKO) 4 embryos, 8 eyes and 50% Cre-negative offspr...
Objective(s):Mesenchymal stem cells (MSCs) derived from Wharton’s jelly (WJ-MSCs) are now much more appealing for cell-based infertility therapy. Hence, WJ-MSCs differentiation toward germ layer cells for cell therapy purposes is currently under intensive study. Materials and Methods: MSCs were isolated from human Wharton’s jelly and treated with BMP4, retinoic acid (RA) or co-cultured on huma...
During early tooth development, multiple signaling molecules are expressed in the dental lamina epithelium and induce the dental mesenchyme. One signal, BMP4, has been shown to induce morphologic changes in dental mesenchyme and mesenchymal gene expression via Msx1, but BMP4 cannot substitute for all the inductive functions of the dental epithelium. To investigate the role of FGFs during early ...
