Osteosarcoma(OS) is a highly aggressive bone cancer for which treatment has remained essentially unchanged for decades. Although OS is characterized by extensive genomic heterogeneity and instability, RB1 and TP53 have been shown to be the most commonly inactivated tumor suppressors in OS. We previously generated a mouse model with a double knockout (DKO) of Rb1 and Trp53 within cells of the osteoblastic lineage, which largely recapitulates human OS with nearly complete penetrance. SKP2 is a repression target of pRb and serves as a substrate recruiting subunit of the SCFSKP2 complex. In addition, SKP2 plays a central role in regulating the …

Faculty, Staff and Student Publications

The Von-Hippel-Lindau (VHL) gene, acting as a tumor suppressor, plays a crucial role in the tumorigenesis of clear cell renal cell carcinoma (ccRCC). Approximately 90% of individuals with advanced ccRCC exhibit somatic mutations in the VHL gene. Belzutifan, orally administered small-molecule inhibitor of hypoxia-induced factor-2α, has demonstrated promising efficacy in solid tumors associated with germline loss-of-function mutations in VHL, including ccRCC. However, its impact on cases with somatic or sporadic VHL mutations remains unclear. Here, we present 2 cases where belzutifan monotherapy was employed in patients with advanced ccRCC and somatic loss-of-function mutations in VHL. Both patients exhibited a swift …

Effect Of Vitamin E Enhanced Highly Cross-Linked Polyethylene On Wear Rate And Particle Debris In Anatomic Total Shoulder Arthroplasty: A Biomechanical Comparison To Ultrahigh-Molecular-Weight Polyethylene, Adam Khan, Andrew Jawa, Matthew J. Smith, J Michael Wiater, Derek J. Cuff, Anand M. Murthi, Luke Stanford Austin

Conference Presentation Abstracts

INTRODUCTION: Particle-induced osteolysis resulting from polyethylene wear remains a source of implant failure in anatomic total shoulder designs. Modern polyethylene components are irradiated in an oxygen-free environment to induce polyethylene cross-linking, but an unfortunate byproduct of this process is free radical production. Melting or heat annealing is one method of reducing free radicals but can compromise the component’s mechanical properties. The antioxidant, Vitamin E, has been introduced as an alternative adjuvant to neutralize free radicals. Specifically, in anatomic shoulder arthroplasty with a ceramic head component, the vitamin E-enhanced polyethylene showed improved wear compared to the conventional highly-cross linked polyethylene. This …

Conference Presentation Abstracts

The field of shoulder arthroplasty has changed markedly since the inception of the reverse total shoulder arthroplasty (RTSA) in 2004. With yearly gains of 32%, the RTSA now encompasses the largest portion of shoulder arthroplasty procedures. In contrast, the anatomic total shoulder arthroplasty (ATSA) and hemiarthroplasty (HA) have steadied or decreased in usage. Some have offered several explanations for these trends, such as expanding indications for the RTSA, in particular for pathologies traditionally treated with ATSA such as glenohumeral arthritis with an intact rotator cuff and no major bone loss/deformity. Others have cited superior postoperative outcomes of the RTSA over …
