      Background: Reversing multidrug resistance (MDR) has been an important goal for clinical and investigational oncologists. In the last few decades, significant effort has been made to search for inhibitors to reverse MDR ...

    • CD44 is a direct target of miR-199a-3p and contributes to aggressive progression in osteosarcoma 

      Gao, Yan; Feng, Yong; Shen, Jacson K.; Lin, Min; Choy, Edwin; Cote, Gregory M.; Harmon, David C.; Mankin, Henry J.; Hornicek, Francis J.; Duan, Zhenfeng (Nature Publishing Group, 2015)
      Osteosarcoma is the most common primary bone malignancy in children and adolescents. Herein, we investigated the role of cluster of differentiation 44 (CD44), a cell-surface glycoprotein involved in cell-cell interactions, ...

    • Characteristics and Patterns of Metastatic Disease from Chordoma 

      Young, Victoria A.; Curtis, Kevin M.; Temple, H. Thomas; Eismont, Frank J.; DeLaney, Thomas F.; Hornicek, Francis J. (Hindawi Publishing Corporation, 2015)
      Chordoma is a rare, slow-growing malignant tumor arising from notochordal remnants. A retrospective review of patient records at two major referral centers was undertaken to assess the incidence, location, and prognostic ...

    • Cross Species Genomic Analysis Identifies a Mouse Model as Undifferentiated Pleomorphic Sarcoma/Malignant Fibrous Histiocytoma 

      Mito, Jeffrey K.; Riedel, Richard F.; Dodd, Leslie; Lahat, Guy; Lazar, Alexander J.; Dodd, Rebecca D.; Stangenberg, Lars; Eward, William C.; Brigman, Brian E.; Jacks, Tyler; Lev, Dina; Mukherjee, Sayan; Kirsch, David G.; Aziz, Syed A.; Hornicek, Francis John; Yoon, Sam Sunghyun (Public Library of Science, 2009)
      Undifferentiated pleomorphic sarcoma/Malignant Fibrous Histiocytoma (MFH) is one of the most common subtypes of human soft tissue sarcoma. Using cross species genomic analysis, we define a geneset from the \(LSL\)-\(Kras^{G12D}\); ...

    • Differences in sex distribution, anatomic location and MR imaging appearance of pediatric compared to adult chordomas 

      Sebro, Ronnie; DeLaney, Thomas; Hornicek, Francis; Schwab, Joseph; Choy, Edwin; Nielsen, G. Petur; Rosenthal, Daniel I. (BioMed Central, 2016)
      Background: Chordomas are rare malignancies that primarily affect adults, but also rarely affect pediatric patients. We compared the imaging appearance, demographic and anatomic distributions of adult and pediatric chordomas ...

    • The Discrepancy between Patient and Clinician Reported Function in Extremity Bone Metastases 

      Janssen, Stein J.; van Rein, Eva A. J.; Paulino Pereira, Nuno Rui; Raskin, Kevin A.; Ferrone, Marco L.; Hornicek, Francis J.; Lozano-Calderon, Santiago A.; Schwab, Joseph H. (Hindawi Publishing Corporation, 2016)
      Background:. The Musculoskeletal Tumor Society (MSTS) scoring system measures function and is commonly used but criticized because it was developed to be completed by the clinician and not by the patient. We therefore ...

    • Expression of programmed cell death ligand 1 (PD-L1) and prevalence of tumor-infiltrating lymphocytes (TILs) in chordoma 

      Feng, Yong; Shen, Jacson; Gao, Yan; Liao, Yunfei; Cote, Gregory; Choy, Edwin; Chebib, Ivan; Mankin, Henry; Hornicek, Francis; Duan, Zhenfeng (Impact Journals LLC, 2015)
      Chordomas are primary malignant tumors of the notochord that are resistant to conventional chemotherapy. Expression of programmed cell death ligand 1 (PD-L1), prevalence of tumor-infiltrating lymphocytes (TILs), and their ...

    • Genotyping Cancer-Associated Genes in Chordoma Identifies Mutations in Oncogenes and Areas of Chromosomal Loss Involving CDKN2A, PTEN, and SMARCB1 

      Choy, Edwin; MacConaill, Laura E.; Cote, Gregory M.; Le, Long P.; Shen, Jacson K.; Nielsen, Gunnlaugur P.; Iafrate, Anthony J.; Garraway, Levi A.; Hornicek, Francis J.; Duan, Zhenfeng (Public Library of Science, 2014)
      The molecular mechanisms underlying chordoma pathogenesis are unknown. We therefore sought to identify novel mutations to better understand chordoma biology and to potentially identify therapeutic targets. Given the ...

    • MDR1 siRNA loaded hyaluronic acid-based CD44 targeted nanoparticle systems circumvent paclitaxel resistance in ovarian cancer 

      Yang, Xiaoqian; lyer, Arun K.; Singh, Amit; Choy, Edwin; Hornicek, Francis J.; Amiji, Mansoor M.; Duan, Zhenfeng (Nature Publishing Group, 2015)
      Development of multidrug resistance (MDR) is an almost universal phenomenon in patients with ovarian cancer, and this severely limits the ultimate success of chemotherapy in the clinic. Overexpression of the MDR1 gene and ...

    • Pharmacokinetics and tolerability of NSC23925b, a novel P-glycoprotein inhibitor: preclinical study in mice and rats 

      Gao, Yan; Shen, Jacson K.; Choy, Edwin; Zhang, Zhan; Mankin, Henry J.; Hornicek, Francis J.; Duan, Zhenfeng (Nature Publishing Group, 2016)
      Overexpression of P-glycoprotein (Pgp) increases multidrug resistance (MDR) in cancer, which greatly impedes satisfactory clinical treatment and outcomes of cancer patients. Due to unknown pharmacokinetics, the use of Pgp ...

    • Recurrent Chromosomal Copy Number Alterations in Sporadic Chordomas 

      Le, Long Phi; Nielsen, Gunnlaugur Petur; Rosenberg, Andrew Eric; Thomas, Dafydd; Batten, Julie M.; Deshpande, Vikram; Schwab, Joseph H; Duan, Zhenfeng; Xavier, Ramnik; Hornicek, Francis John; Iafrate, Anthony John (Public Library of Science, 2011)
