Adamts4 coordinates the transcriptomic profile of primary rat costal chondrocytes.

ABSTRACT: Chondrocytes play a pivotal role in cartilage tissue engineering. ADAMTS4 gene encodes aggrecanase-1, which is known to affect chondrocyte biology by regulating aggrecan degradation. However, the molecular mechanism by which ADAMTS4 regulates chondrocyte phenotype remains unclear. To comprehensively investigate Adamts4-regulated genes in primary rat costal chondrocytes, we conducted siRNA-mediated Adamts4 knockdown alongside RNA sequencing (RNA-seq), co-immunoprecipitation coupled with mass spectrometry (CO-IP/MS), and enhanced RNA immunoprecipitation sequencing (iRIP-seq). Our results demonstrated that Adamts4 knockdown did not affect chondrocyte apoptosis. However, Adamts4 silencing markedly changed the expression levels of numerous genes linked to cell differentiation and cell cycle pro
