Bethesda, MD – Dr. Barr's research interest is molecular genetics of cancer with a focus on recurrent chromosomal alterations in sarcomas. His research team has most recently been conducting a multidisciplinary approach to understand the biological consequences of these genetic events in rhabdomyosarcoma, a family of pediatric soft tissue cancers. Major focal points of this research program are fusions of the PAX3 or PAX7 gene with the FOXO1 (FKHR) gene to generate fusion oncoproteins and the amplification of several oncogenic loci. These studies revealed that the gene fusions result in an aberrant gene expression program that contributes to tumorigenesis. Amplification events involving known and new candidate oncogenes occur in specific gene fusion subsets and are associated with distinct clinical outcomes. Current studies are examining tumorigenic effects, functional domains, downstream targets, regulation of gene expression, and clinical applications.

Carbondale, IL – Research in my lab is focused on gene regulatory mechanisms in a development system. We focus on the specification and differentiation of skeletal muscle which is controlled by four highly related basic helix loop helix proteins referred to as the Myogenic Regulatory Factors, or MRFs. Much of the work in the lab is focused on understanding the function and specificity of myogenin, the only MRF singly required for viability. Our research is directed towards understanding the regulation of the genes controlled by myogenin by determining promoter elements that control expression and identifying additional protein factors that contribute to the unique role of myogenin on these genes, including chromatin modifying factors and additional transcription activators and co-activators.

Brescia, Italy – The Fanzani lab currently focuses in establishing the functional role of the different caveolar proteins, termed Caveolins and Cavins, in the progression of rhabdomyosarcoma. These multifunctional proteins play a pivotal role in the generation of the plasma membrane domains known as caveolae, which are involved in endocytosis, cholesterol homeostasis and signal transduction. Understanding whether and how these proteins may facilitate or hamper the development of rhabdomyosarcoma is our main goal.

Columbus, OH – The Guttridge Lab at Ohio State investigates the role of the nuclear factor kappa-B (NF-κB) family of transcription factors in the growth and development of skeletal muscle. Recent lab findings have supported the idea that NF-κB functions as an inhibitor of cellular differentiation and have further elucidated the many mechanisms by which this occurs. Current projects in the lab are investigating the NF-κB signaling in myogenesis, rhabdomyosarcoma, Duchenne muscular dystrophy, and cancer cachexia.

Göttingen, Germany – Cancer is a disease that results from inappropriate cell division induced by hyperproliferation. In many cases, the development of cancer is associated with genes or signaling pathways important for patterning during embryogenesis. We investigate the role of the Hedgehog/Patched (Hh/Ptch) signaling cascade in the development of solid tumors. The focus is on tumors caused by mutations in Ptch, such as medulloblastoma, rhabdomyosarcoma and basal cell carcinoma.

Durham, NC – Sarcomas are among the most difficult-to-treat cancers in pediatric oncology, with metastatic forms having the highest mortality. We have established genetically defined human cell-based models for the pediatric skeletal muscle cancer known as rhabdomyosarcoma. Current therapies are based on xenograft models in immunocompromised mice, using established patient-derived patient cell lines, but because of the genetic variability of these cell lines, a true understanding of the causative role of certain genetic changes (e.g. chromosomal translocations) in rhabdomyosarcoma formation is not understood. Specific goals of this research program include the identification of signaling pathways corrupted in rhabdomyosarcoma, with focus on the PAX3-FOXO1 mutation and its downstream effectors, and identification of new therapeutic targets for treatment of this childhood cancer.

Buffalo, NY – The research program in Dr. Mal's laboratory is focused on broad but highly integrated areas of study. The epigenetic gene regulation program involves identifying the epigenetic changes and deciphering the mechanism as a potential target strategy for therapy. This program is aimed to identify the epigenetic mechanism regulating normal and perturb differentiation. Particularly, the research focuses on epigenetic modulation of gene expression regulating skeletal muscle differentiation during development and regeneration, as well as in muscle tumor rhabdomyosarcoma (RMS). The drug discovery program involves searching small molecule modulators that would activate the skeletal muscle differentiation program in multipotent muscle stem cells (satellite cells) and in RMS tumor cells. Both programs are aimed at therapeutic applications for skeletal muscle associated tumors and degenerative diseases.

Toronto, ON, Canada – Dr. Malkin's research interests are closely integrated with his clinical field of expertise. Specifically, his research program focuses primarily on genetic mechanisms of childhood cancer susceptibility, and the genetic basis of childhood sarcomas (cancers of bone, muscle and other soft tissues). His research team was the first to demonstrate that highly variable regions of DNA, termed copy number variations, are found in excess in the blood of some people, both children and adults, at very high risk of developing cancer, and may represent the earliest genetic changes that ultimately lead to development of cancer. Recently, his work has focused on application of this genetic/genomic information to develop rational clinical surveillance and treatment guidelines for children and adults deemed at genetic ‘high risk’ for cancer. In his sarcoma work, Dr. Malkin has studied the molecular and cell biology pathways that are associated with the development and progression of these cancers, and has identified molecules that might represent viable targets for novel drug therapies.

Rossella Rota Lab – Website in Progress

Rome, Italy – Our research interest is to investigate the mechanisms responsible for the inability of tumor cells to differentiate towards the cell lineage of origin. The main goal of our investigations on rhabdomyosarcoma, a soft-tissue sarcoma of myogenic origin, is the reactivation of the de-regulated pathways inhibiting skeletal muscle cell determination to achieve tumor cell cycle arrest and differentiation. Specifically, we evaluate, in in vitro and in vivo rhabdomyosarcoma models, the crosstalk among some developmental networks driving embryonic myogenesis such as transcription factors, chromatin modifying regulators and non-coding RNA to identify new therapeutic anti-cancer targets.

London, UK – The current aims of the Sarcoma Molecular Biology Team are to identify therapeutic targets and/or molecular markers that will aid the treatment of patients with specific types of soft tissue sarcomas, as well as continuing a more minor interest in testicular germ cell tumours. Gene products relevant to sarcoma biology are identified through analyses of data from various screening approaches, including gene expression profiling, high-throughput sequencing and analysis of genomic copy number changes. This work is supported through use of extensive, well-characterised tumour collections. The functional relevance of selected gene products in specific sarcomas is evaluated using in vitro and in vivo experimental models.

Los Angeles, CA – The overarching goal of our research is to improve the outcome for patients with cancer. To do so, we seek to better understand the underlying genetic mechanisms that drive the development of cancer, or oncogenesis. In addition, we hope to utilize this newfound knowledge to identify therapeutic targets and deliver targeted therapies to tumor cells using nanoparticle delivery therapy.

Click HereZammit Lab

London, UK – The Zammit group's core research aims to understanding the regulation of satellite cell function in both normal and diseased muscle. The functional unit of skeletal muscle is the myofibre: a giant syncytial cell maintained by hundreds of myonuclei. Growth, maintenance and repair of the post-mitotic myofibres is performed by satellite cells. These resident stem cells are located on the edge of muscle fibres, below the surrounding basal lamina.

Click HereWager Lab

Cambridge, MA – Effective functioning of the body’s tissues and organs depends upon innate regenerative processes that maintain proper cell numbers (homeostasis) and replace damaged cells after injury (repair). In many tissues, regenerative potential is determined by the presence and functionality of a dedicated population of stem and progenitor cells, which respond to exogenous cues to produce replacement cells when needed. Understanding how these unspecialized precursors are maintained and regulated is essential for understanding the fundamental biology of tissues. In addition, this knowledge has practical implications, as the regenerative potential of tissue-specific stem and progenitor cells can be exploited therapeutically by transplantation (to replenish the stem cell pool) or by endogenous manipulation (to boost the repair activity of cells already present in the tissue).
