Who We Are

Meet the Program Advisory Committee

The members of the Program Advisory Committee serve under the authority of their respective institutional presidents as the governing body of the Bone Disease Program of Texas. Additionally, the Committee has an external advisor. Most recently, the Committee added Dr. Thomas Hunt III from Baylor College of Medicine and Dr. Roland Baron from Harvard School of Dental Medicine.  

 

Robert F. Gagel, M.D.

Director, Bone Disease Program of Texas
Professor and Head, Division of Internal Medicine

Recognizing that bone health had not been a priority in Houston or the Texas medical community, Dr. Gagel worked with other physicians and members of the Houston community, including C. Berdon Lawrence, to establish the Bone Disease Program of Texas. Over the past three decades, Dr. Gagel has made significant contributions to bone research, including studies on calcitonin, a major regulator of bone resorption.

Dr. Gagel has focused on the clinical management of osteoporosis and other disorders of bone metabolism. He is a charter member of the American Society for Bone and Mineral Research and for the past 30 years has been broadly involved in the development of strategies to prevent and treat osteoporosis.

Dr. Baron has studied multiple aspects of skeletal biology ranging from cell differentiation and function to regulation of bone remodeling in health and disease. His laboratory was the first to show proton secretion by osteoclasts and to establish polarity of membrane domains, vesicular and ion transport in the osteoclast. This was followed by significant contributions to the understanding of integrin signaling and, in particular, the role of Src tyrosine kinase in the establishment of osteoclast polarity and in the organization and regulation of actin-based podosomes in osteoclasts.

Dr Baron's interest in translational medicine and drug discovery led his laboratory to integrate their molecular work in the framework of cellular basis of bone remodeling for the purpose of therapeutic intervention. Dr Baron is also the founder and Editor-in-Chief of the journal Bone. He has received numerous national and international awards.

I am a Medical Physicist licensed to practice in the state of Texas.

Phone: 713-834-6376

My laboratory is studying the transcriptional control of cartilage and bone formation, more specifically, the role of the transcription factor Sox9 in chrondrocyte differentiation and the role of the transcription factor Osterix in the differentiation of osteoblasts and osteocytes. Our previous work has focused on the essential role of these transcription factors during embryonic development. More recently we have examined the physiological role of Sox9 in the homeostatic control of mouse articular cartilage and intervertebral discs postnatally. We are also exploring the mechanisms by which Sox9 controls its target genes as well as the extent of the genetic program controlled by Sox9 in chrondrocytes. In other work, we study the multiple functions of Osterix in the control of bone homeostasis in growing and adult bones.

I was invited to present the Louis V. Avioli Memorial Lecture at this year's meeting of the American Society of Bone and Mineral Research. I also received the Senior Investigator Award at this year's meeting of the American Society of Matrix Biology.

As a physician scientist I focus on osteosarcoma, both in the clinic and the lab. Our laboratory investigates mechanisms of metastasis and therapy resistance in osteosarcoma, focusing particularly on cell signaling and pathways that may be targets of small molecular medicines, especially the Notch and ERBB signaling pathways. Since Notch is difficult to target with inhibitory therapies, our laboratory is exploring the regulation of this pathway in sarcoma, both upstream and downstream of Notch, itself, to find better therapeutic targets.

 

Robert F. Gagel, M.D. 

Co-Director, Rolanette and Berdon Lawrence Bone Disease Program of Texas
Head, Division of Internal Medicine
Professor of Medicine, Department of Endocrine Neoplasia and Hormonal Disorders
MD Anderson Cancer Center
Email: rgagel@mdanderson.org
Phone: 713-792-6517

My primary clinical focus within the Section of Bone and Mineral Disorders, Department of Endocrine Neoplasia and Hormonal Disorders, is the prevention and treatment of osteoporosis in patients with cancer. We have established programs to address bone loss in the context of breast cancer, stem cell transplant, and leukemia. We also look for opportunities to optimize bone health in other malignancies

My research program is focused on the bone resorption inhibitor, calcitonin. Our lab created a mouse model of calcitonin deficiency by deleting the calcitonin/CGRP gene. These animals have an interesting phenotype distinguished by cortical and trabecular thinning and a redistribution of cortical bone to trabeculae in the pericortical region.  Deficiency of calcitonin also leads to modulation of several regulatory molecules responsible for bone formation, suggesting a link between calcitonin and bone formation. In addition, calcitonin/CGRP -/- mice have a distinctive phenotype characterized by splenomegaly and a defect in regulation of T lymphocytes. Studies are being performed to characterize these phenotypes.

Khalid A. Mohamedali, Ph.D.

Phone: 713-792-5953

My research program focuses primarily on the development of targeted therapeutic agents for cancer therapy, particularly in relation to bone metastasis. We have tested agents targeting breast and prostate cancer metastasis and growth in bone in various mouse models, leading to a better understanding of the mechanisms by which tumor cells target the bone and promote osteoblastic and osteolytic effects. Of particular interest is the role that bone marrow derived cells (BMDCs) play in all aspects of bone metastasis. Studies to identify BMDC populations that may play a role in tumor growth in bone are currently under way in our laboratory. 

 

Nora Navone, Ph.D.

Associate Professor
Department of Genitourinary Medical Oncology
MD Anderson Cancer Center
Email: nnavone@mdanderson.org
Phone: 713-563-7273

The main focus of my laboratory research is to study the pathogenesis of prostate cancer bone metastases. Prostate cancer has clinical features unique among adult solid tumors, including high tropism for bone and the osteoblastic nature of most bone metastases. Yet little is known about the dynamic interactions between prostate cancer cells and bone cells essential to the growth of metastatic cells in the bone. We have, thus, approached our studies by investigating the nature of the prostate cancer-cell-osteoblast interactions and how they exacerbate progression of prostate cancer in bone. This focus on tumor-bone interactions, rather than on 'standard' studies that examine biologic changes in tumor cells alone, is a unique aspect of my research program. The goals of my studies are to develop better models for mimicking prostate cancer growth in the bone and then using these models to enhance our understanding of the process of molecular interactions between prostate cancer and bone cells required in metastasis. Continued emphasis is placed on translating these results into more effective therapeutic targets and prognostic measures.

Phone: 713-834-6377 (lab)

For the past several years working in the lab of Dr Benoit deCrombrugghe, my research interest has been on the regulation of Osterix (Osx) function during osteoblast differentiation. Osx is an osteoblast-specific transcription factor which is required for bone formation. Recently we identified the chromatin protein NO66 as an Osx-interacting protein using a proteomic approach. NO66 is a histone demethylase, negatively regulates Osx transcriptional activity and inhibits osteoblast differentiation and maturation. We are currently involved in exploring the biological role of NO66 in osteoblasts using mouse genetic approach as well as the epigenetic control of Osx target genes expression during bone formation.
