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.

Project description:Gene-specific transcription factors (GSTFs) control of gene transcription by DNA binding and specific protein complex recruitment, which regulates promoter accessibility for transcription initiation by RNA polymerase II. GSTFs that are frequently mutated in colon and rectal carcinomas are Suppressor of Mothers Against Decapentaplegic 2 (SMAD2) and SMAD4, which play an important role in the TGF-β signaling pathways controlling cell fate and proliferation (ref.). The SMAD protein family is a diverse and it can be divided into three subclasses: receptor activated SMADs, inhibitory SMADs and the common SMAD4 co-activator. To study protein interactors of the SMAD protein family we generated a quantitative proteomics pipeline that allows for inducible expression of GFP-tagged SMAD proteins followed by affinity purification and MS analysis. The nuclear importin IPO5 was identified as a novel interacting protein of SMAD1. Overexpression of IPO5 shows forced BMP R-SMAD nuclear localization confirming a functional relationship between BMP but not TGF-β R-SMADs and IPO5. Finally we provide evidence that the length of the lysine stretch in the NLS is involved in importin selection.

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:To identify proteins phosphorylated by Akt downstream of PI3K-mediated PDGFRalpha signaling, we immunoprecipitated Akt phosphorylation substrates from PDGF-AA-treated primary mouse embryonic palatal mesenchyme (MEPM) lysates and analyzed the peptides by nano LC-MS/MS.
