·Role of Cathepsin K in Bone Invasion of Pituitary Adenomas: A Dual Mechanism Involving Cell Proliferation and Osteoclastogenesis.

This study aimed to investigate the regulation and underlying mechanism of Cathepsin K (CTSK) in bone-invasive pituitary adenomas (BIPAs). A total of 1437 patients with pituitary adenomas were included and followed up. RNA sequencing, immunohistochemistry, and qRT-PCR were used to analyze CTSK expression.
