Research Interest:


Our laboratory studies the NF-kB family of transcription factors and the role they play in cell growth and differentiation.  Aside from NF-kB’s more recognizable role in regulating immune response, strong evidence suggests that the NF-kB signaling pathway is also involved in tumor progression. However, exactly how NF-kB functions in cellular transformation has not been resolved. To further understand this disease property of NF-kB, my laboratory is using skeletal muscle as a model of cellular growth and differentiation. Skeletal muscle maturation involves growth arrest and fusion of progenitor myoblasts into terminally differentiated myofibers. Our findings have elucidated that NF-kB acts in this system as an inhibitor of differentiation, and we have further identified that this activity can occur through multiple mechanisms. More recently, our group has expanded studies using in vivo models of muscle regeneration, where results support the notion that NF-kB functions in skeletal muscle to limit it’s regenerative potential. We believe this function of NF-kB may be relevant in muscle diseases such as Duchenne muscular dystrophy and cancer cachexia. The long-term goal is to not only to better dissect the function and mechanisms by which NF-kB regulates muscle differentiation and turnover associated with muscle disorders, but to also translate this information into better understanding the role of NF-kB in developing tumors.
