Project description:The BMP signaling pathway regulates multiple steps of hematopoiesis, mediated through receptor-regulated Smads, including Smad1 and Smad5. Here we use loss-of-function approaches in zebrafish to compare the roles of Smad1 and Smad5 during embryonic hematopoiesis. Microarray experiments revealed that the two proteins regulate redundantly the key initiators of the hemato-vascular program, including scl, lmo2, and gfi1. However, each also regulates a remarkably distinct genetic program, with Smad5 uniquely regulating the BMP signaling pathway itself. Our results suggest that specificity of BMP signaling output, with respect to hematopoiesis, can be explained by differential functions of Smad1 and Smad5. Keywords: Gene expression transcript profiles The experiment was designed to identify the unique Smad1 and Smad5 dependent transcripts during the somitogenesis stage of development, during which mesoderm is specified to the hematopoietic lineage. Embryos were injected with translational blocking morpholinos for Smad1, Smad5 or both, and then collected at the 1-somite stage for RNA extraction. For every experiment control uninjected wildtype sibling embryo were also collected for comparison. Three biological replicates were done for each knockdown set. Total RNA was sent to Nimblegen for cDNA synthesis, dye labeling and hybridization. Single knockdown samples were hybridized to the Nimblegen 2006 Danio rerio Gene Expression Array chip and the double knockdown samples to the 2007 verison of the chip, which contains the same test genes, but with additional control oligos. Dye swaps were done for each set; for 2 of the 3 hybridization in each set Cy3 was the dye used for the experimental sample and in the 3rd Cy5 was used. The raw hybridization data was obtained from Nimblegen, normalized using NimbleScan and anaylzed using R software.

Project description:SOX9 is well-known for its role in chondrogenesis and gonadogensis. Campomelic Dysplasia (CD) is an example of SOX9 haploinsufficiency-caused rare congenital disease, in which the patients are reported to have skeletal abnormalities. In this study, we created a hiPSC-modeling CD patient and investigated the effect of SOX9 on the regulation of chondrocyte differentiation in BMP-SMAD signaling in vitro. In the CD patient transcriptome, the BMP-SMAD signaling pathway and ribosome-related and chromosome segregation-related gene sets were altered. Upon further experimentation, noggin was found to be significantly upregulated in HT and HM mutants. The overexpression of SOX9 also showed upregulation in SOX9 and COL2A1. . We hope this finding can give a better picture of the dosage-dependent role of SOX9 in chondrogenesis and reveal the manifestation of skeletal dysplasia in CD patients, thereby helping to develop better drugs for these patients.

Project description:The specification of cartilage requires Sox9, a transcription factor with broad roles for organogenesis outside the skeletal system. How Sox9 gains selective access to cartilage-specific cis-regulatory regions during skeletal development had remained unclear. By analyzing chromatin accessibility during the differentiation of neural crest cells into chondrocytes of the zebrafish head, we find that cartilage-associated chromatin accessibility is dynamically established. Cartilage-associated regions that become accessible after neural crest migration are co-enriched for Sox9 and Fox transcription factor binding motifs. In zebrafish lacking Foxc1 paralogs, we find a global decrease in chromatin accessibility in chondrocytes, consistent with a later loss of dorsal facial cartilages. Zebrafish transgenesis assays confirm that many of these Foxc1-dependent elements function as enhancers with region- and stage-specific activity in facial cartilages. We propose that Foxc1-dependent chromatin accessibility helps directs the versatile Sox9 protein to a chondrogenic program in the face.

Project description:Non-syndromic facial asymmetry is commonly found in dentofacial deformity populations with skeletal malocclusions. Asymmetry of this type may result from imbalanced growth and function of both the jaw and associated muscles. Among the multiple genes that interact to affect the craniofacial musculoskeletal complex during pre and postnatal growth and development, NODAL signaling pathwy (NSP) genes are active in adult skeletal muscle and may be key factors in development, growth and maintenance of facial asymmetry. It is of interest to determine whether expression of NODAL pathway genes might differ in masseter muscles between individuals with malocclusion that have facial asymmetry and normal symmetry. Human Transcriptome 2.0 GeneChips (HTA2.0) were used to examine global gene expression in masster muscles between malocclusion subjects with posterior facial asymmetry and with normal facial symmetry.

Project description:The canonical bone morphogenetic protein (BMP) signaling pathway plays a crucial regulatory role in tooth development by activating Smad proteins to regulate gene expression. We previously identified an atypical canonical BMP signaling in dental mesenchyme that is Smad4-independent but Smad1/5-dependent. This study demonstrates that phosphorylated Smad1/5 (pSmad1/5) and Smad4 regulate distinct gene sets in dental mesenchyme. Real-time monitoring of BMP-Smad transcriptional activity revealed that Smad4-dependent canonical BMP signaling is restricted to neurovascular cells surrounding the condensed dental mesenchymal cells where pSmad1/5 is present. Notably, pSmad1/5 in dental mesenchymal cells form complexes with pSmad3 to prevent canonical BMP signaling. CUT&RUN assays revealed genome-wide co-occupancy of pSmad1/5 and pSmad3, indicating their function as transcriptional regulation units. Integrative analyses demonstrated that this atypical canonical BMP signaling regulates tooth sensory innervation and maintains odontogenic inductive potential in dental mesenchyme, enabling the identification of critical genes for maintaining tooth inductive capability. Our findings elucidate the operating mechanism of atypical canonical BMP signaling in dental mesenchymal cells and clarify how BMP-Smad signaling exerts diverse functions across different cell types, informing future tooth bioengineering strategies.
