Project description:Fibrosis is driven by activated fibroblasts, but key transcriptional regulators remain unclear. We investigated the role of RUNX2 using three human skin fibroblast lines with RUNX2 knockdown (shRUNX2) and matched controls (shControl), treated with or without TGF-β, followed by bulk RNA sequencing. RUNX2 depletion attenuated TGF-β–induced pro-fibrotic gene programs, including extracellular matrix organization and myofibroblast differentiation. In primary fibroblasts, the small molecule F0565-0303 reduced TGF-β–induced fibrotic signatures and decreased RUNX2 expression, partially mimicking RUNX2 knockdown, while showing minimal effects under basal conditions. These results identify RUNX2 as a key driver of fibroblast activation and support its pharmacological targeting as an anti-fibrotic strategy.

Project description:Runx2 and Axin2 regulate skeletal development. We recently determined that Axin2 and Runx2 molecularly interact in differentiating osteoblasts to regulate intramembranous bone formation, but the relationship between these factors in endochondral bone formation was unresolved. To address this, we examined the effects of Axin2 deficiency on the cleidocranial dysplasia (CCD) phenotype of Runx2+/- mice, focusing on skeletal defects attributed to improper endochondral bone formation. Axin2 deficiency unexpectedly exacerbated calvarial components of the CCD phenotype in the Runx2+/- mice; the endocranial layer of the frontal suture, which develops by endochondral bone formation, failed to mineralize in the Axin2-/-:Runx2+/-mice, resulting in a cartilaginous, fibrotic and larger fontanel than observed in Runx2+/- mice. Transcripts associated with cartilage development (e.g., Acan, miR140) were expressed at higher levels, whereas blood vessel morphogenesis transcripts (e.g., Slit2) were suppressed in Axin2-/-:Runx2+/-calvaria. Cartilage maturation was impaired, as primary chondrocytes from double mutant mice demonstrated delayed differentiation and produced less calcified matrix in vitro. The genetic dominance of Runx2 was also reflected during endochondral fracture repair, as both Runx2+/- and double mutant Axin2-/-:Runx2+/- mice had enlarged fracture calluses at early stages of healing. However, by the end stages of fracture healing, double mutant animals diverged from the Runx2+/- mice, showing smaller calluses and increased torsional strength indicative of more rapid end stage bone formation as seen in the Axin2-/- mice. Taken together, our data demonstrate a dominant role for Runx2 in chondrocyte maturation, but implicate Axin2 as an important modulator of the terminal stages of endochondral bone formation. 4 mice per genotype X 4 genotypes: wildtype (WT), Runx2+/- (R-Het), Axin2-/- (A-KO), Axin2-/-:Runx2+/- (A-KO:R-Het).

Project description:To investigate the genome-wide transcription targets of RUNX2 in MC3T3-E1 cells, cleavage under targets and tagmentation (CUT&Tag) was performed using antibody against RUNX2. Following CUT&Tag, DNAs were amplified using non-biased conditions, labeled, and sequenced with Illumina NovaSeq 150PE.

Project description:In this study, we demonstrated that baseline SOX11 expression was significantly higher in dermal fibroblasts (DFs) isolated from patients with SSc than that in controls, and increased in response to TGF-b. We then showed that SOX11 is involved in the expression of periostin and some periostin-dependent fibrotic factors identified in lung fibroblasts previously. Moreover, we identified some fibrotic factors induced by SOX11 in DNA microarrays combining TGF-b induction and SOX11 knockdown. Finally, we showed that genetic deletion of SOX11 in Postn positive fibroblast cells protects from bleomycin (BLM)-induced skin fibrosis. Altogether, our data indicate that SOX11 and periostin forms a vicious circle and that TGF-b activates this circle specifically in SSc dermal fibroblasts.
