GSE146111: -catenin inhibits adipogenic differentiation of hypertrophic chondrocytes and promote osteogenesis

Bulk RNA sequencing

It has been shown that hypertrophic chondrocyte (HC) can become osteoblast, contributing to the formation of trabecular bone and endosteum. However, it is unclear what genes regulate the process of differentiation from chondrocyte to osteoblast. Conditional knock-out of catenin in HCs can reduce the trabecular bone amount and there is also some evidence that ablation of catenin in HCs can promote bone marrow adipogenesis. Conditional stabilization of catenin in HCs results in osteopetrosis. In order to investigate the gene regulatory network with different dosage of catenin in HC descendants (i.e. in Loss-of-Function mutant, Gain-of-Function mutant and Wildtype control), we collected HC descendant cells from proximal tibia of mice at postnatal day 5 and performed bulk RNA seq to profile the gene expression pattern in HC descendants.
