Project description:FBS and BMP influence the somatic reprogramming induced by Oct4/Sox2/Klf4/c-Myc similarly. Bone morphogenetic proteins (BMPs) are abundant in serum and activate Smad1/5/8 to regulated target genes. BMPs play a important role in ES self-renewal, neurogenesis, osteogenesis, angiogenesis. We performed this experiment for identify what targets are regulated by BMPs and FBS.

Project description:Bone Morphogenetic Proteins (BMPs), a subgroup of the TGF-ï¢ superfamily, were originally isolated from bone on the basis of their ability to induce ectopic bone development. While BMPs are involved in a wide range of developmental and physiological functions, very few vertebrate target genes in this pathway have been identified. To identify target genes regulated by the BMP growth factor family in Xenopus, large-scale microarray analyses were conducted to discover genes directly activated by this factor in dissociated animal cap tissues treated with a combination of the protein synthesis inhibitor cycloheximide and BMP2.

Project description:Bone morphogenetic proteins (BMPs) are extracellular signaling molecules that belong to the transforming growth factor beta (TGF-β) superfamily. By regulating target gene transcription, BMPs control various cellular processes, such as proliferation, differentiation, apoptosis and migration. In addition, rBMP2 was used to observe BMP signaling in treatment of ovarian cancer cell line SK-OV-3. We attempted to address the possible roles of BMP signaling by inhibiting a wide-range of downstream pathways using a small molecule inhibitor of type I BMPRs, dorsomorphin. The potential utility of this molecule as a molecular inhibitor of BMP signaling in treatment of ovarian cancer cell line SK-OV-3 was also evaluated.

Project description:The BMP/TGFβ-Smad, Notch and VEGF signaling guides formation of endothelial tip and stalk cells. However, the crosstalk of bone morphogenetic proteins (BMPs) and vascular endothelial growth factor receptor 2 (VEGFR2) signaling has remained largely unknown. We demonstrate that BMP family members regulate VEGFR2 and Notch signaling, and act via TAZ-Hippo signaling pathway. BMPs were found to be regulated after VEGF gene transfer in C57/Bl6 mice and in a porcine myocardial ischemia model. BMPs 2/4/6 were identified as endothelium-specific targets of VEGF. BMP2 modulated VEGF-mediated endothelial sprouting via Delta like Canonical Notch Ligand 4 (DLL4). BMP6 modulated VEGF signaling by regulating VEGFR2 expression and acted via Hippo signaling effector TAZ, known to regulate cell survival/proliferation, and to be dysregulated in cancer. In a matrigel plug assay in nude mice BMP6 was further demonstrated to induce angiogenesis. BMP6 is the first member of BMP family found to directly regulate both Hippo signaling and neovessel formation. It may thus serve as a target in pro/anti-angiogenic therapies.

SK-OV-3 cells were incubated in 12 separate culture dishes, 3 dishes with PBS, 3 dishes with recombinant BMP2 (rBMP2) (100 ng/ml), 3 dishes with DM (5 μM) and 3 dishes with recombinant BMP2 (rBMP2) (100 ng/ml) plus DM (5 μM) in the culture medium for 24 hours prior to the analysis.

Project description:Salivary glands produce saliva and play essential roles in digestion and oral health. Pluripotent stem cell-derived (PSC) organoids provide a powerful platform for studying salivary gland development and developing new regenerative therapy. The previous protocol of PSC-derived salivary gland organoids required complicated manufacturing processes, which hampered the organoids for basic research and clinical application.Here, by mimicking the regulatory mechanism of developing salivary glands, we reported the differentiation of induced embryonic salivary glands (iE-SGs) from mouse embryonic stem cells by step-wise treatment of retinoic acid and FGF10. We showed that the iE-SGs recapitulated early morphogenetic events, including the thickening and invagination of the salivary gland placode, and then formed initial buds. The iE-SGs also differentiated into developing ducts structures and could develop to striated and excretory ducts when transplanted in vivo. RNA- seq revealed that iE-SGs had gene expression profiles similar to mouse embryonic SMGs. Thus, our study provided an easy and safe method to generate iE-SGs and offered possibilities for studying events during salivary gland morphogenesis in vitro

Project description:Numerous studies have established a critical role for BMP signaling in skeletal development. In the developing axial skeleton, sequential SHH and BMP signals are required for specification of a chondrogenic fate in somitic tissue. A similar paradigm is thought to operate in the limb, but the signals involved are unclear. To investigate the nature of these signals we examined BMP action in mesenchymal populations derived from the early murine limb bud (~ E10.5). These populations exhibited a graded response to BMPs, in which early limb mesenchymal (EL) cells (from the distal hind limb) displayed an anti-chondrogenic response, whereas BMPs promoted chondrogenesis in older cell populations. To better understand the molecular basis of disparate BMP action in these various populations, gene expression profiling with Affymetrix microarrays was employed to identify BMP-regulated genes. These analyses showed that BMPs induced a distinct gene expression pattern in the EL cultures versus later mesenchymal limb populations (IM and LT).

Project description:Although the salivary transcriptome of adult mosquitoes has been thoroughly described in several recent papers, very little information exists regarding the biological role of larval salivary glands in the Culicidae. We used whole-transcriptome Affymetrix® chips to compare the transcriptional profiles of Anopheles gambiae larval (L4) salivary glands and whole larvae. We identified a total of 277 transcripts as being significantly enriched in the salivary glands. Based on available annotation for the known or predicted protein sequences encoded by these transcripts, 41 were identified as corresponding to secreted proteins, 233 as corresponding to non-secreted (housekeeping) proteins, and 3 as encoding proteins of unknown function. Based on functional annotation of the putatively secreted gene products, we propose that larval salivary secretions have roles in nutrient digestion, detoxification, immunity, and mouthpart lubrication. Interestingly, several components of the larval saliva (e.g. apyrase and serine proteases) have also been reported to exist in adult female saliva, where they are though to help regulate a vertebrate hostâs immune response to bloodfeeding. In conclusion, our results suggest that the salivary glands are important components of both the digestive and immune systems of larval mosquitoes, and that their study might provide clues about the evolution of adaptations to bloodfeeding observed in adults. Experiment Overall Design: We attempted to identify transcripts that are both present and significantly enriched in the salivary glands (SG) of the 4th instar Anopheles gambiae larva. Transcripts were considered as present in the SG if the built-in Affymetrix detection call scored them as such in all three biological replicates of the experiment. Expression values (i.e. signal intensities) of transcripts from the salivary glands were compared to those of a matching group of whole 4th instar larvae using a t-test. Transcripts showing an expression value two-fold or higher (p < 0.01; false discovery rate=1%) in the SG as compared to whole larvae were considered to be significantly enriched.
