My lab investigates the role of proteins and non-coding RNAs in the initiation of multiple myeloma (MM), with the goal of designing new therapeutic strategies for MM. MM is a cancer characterized by proliferation of plasma cell colonies in the bone marrow. Increasingly, evidence shows that a super family of small (20~24 nt) non-coding RNAs, termed microRNAs (miRNAs), are involved in cell differentiation, proliferation, and apoptosis by targeting the 3’UTR of mRNAs of protein-coding genes, and therefore are involved in cancer pathogenesis, including MM. Currently, my research group is working on four projects related to this topic:

  • We are analyzing the role of miRNAs and noncoding RNAs in MM initiation and progression using a genetically engineered mouse model and mouse model of human MM dissemination.
  • We are functionally identifying the key downstream protein targets of miRNAs and noncoding RNAs related to MM progression.
  • We are identifying and characterizing new miRNAs and noncoding RNAs related to MM initiation, progression, and drug resistance.
  • We are developing a mouse model that recapitulates human MM for preclinical studies.
The long-term goal of the Zhao lab is to test novel microRNAs and noncodng RNAs as potential diagnostic or prognostic markers and as therapeutic tools and targets to ultimately translate the knowledge gained to improved MM treatments.

In other words ...

We study multiple myeloma, the second most frequently diagnosed hematologic cancer in the United States. Many genes contain blueprints for proteins, but many others have the blueprints for molecules called miRNAs and noncoding RNAs that do not code for proteins.  These miRNAs and noncoding RNAs, however, are quite important in regulating genes and are clearly involved in the development and progression of cancer, as well as other diseases.  Right now, we have several projects that focus on the roles of miRNA and noncoding RNAs in multiple myeloma.  We are investigating how miRNA and noncoding RNAs initiate the growth and further development of multiple myeloma.  In addition, we are identifying novel genes and miRNAs and noncoding RNAs involved in the development of multiple myeloma. Finally,  because testing potential new drugs requires models that resemble the human disease as closely as possible, we are developing a new mouse model that recapitulates human multiple myeloma for preclinical studies.
