Molecular mechanisms of the induction of differentiation and inhibition of the cancer phenotype; genes affecting the control of differentiation and viability, MCL1 and other genes in the BCL2 family
Dr. Craig's research is centered on understanding the role of MCL1 in normal cell development and in cancer. MCL1 and pro-survival members of the BCL2 family maintain cell viability, while other family members promote cell death. The expression of the MCL1 mRNA and the stability of the MCL1 protein are modulated by environmental cues such as growth and differentiation factors. This serves to maintain and amplify cell types and lineages that are needed by the organism, while eliminating cells that are not needed or are damaged or senescent. However, loss of the normal regulated pattern of expression of MCL1 can allow for prolonged cell survival, further tumorigenic changes , and increased resistance of cancer cells to damaging stimuli and therapeutic drugs.
The work in Dr. Craig’s laboratory focuses on how MCL1 and other pro-survival genes contribute to the ongoing maintenance of homeostasis in hematopoietic and lymphoid cells, and on how alterations affecting the regulation of these genes can lead to the development of leukemia and lymphoma. The long-term goal is to utilize understanding of the role of genes that control survival, prominently MCL1, in order to regulate normal B-, T-, and hematopoietic cell development and to inhibit tumorigenesis. Major questions being addressed in the laboratory are listed below.
Rotations and Thesis Projects:
1. Can MCL1 expression be manipulated to enhance the function of normal lymphocytes and other immune cells, to enhance responsiveness to infection in young as well as aging animals?
2. How are the various pathways that normally regulate MCL1 coordinated, and what alterations promote survival and drug resistance in cancer?
3. Can MCL1 degradation be enhanced in tumor cells to promote death and enhance sensitivity to other chemotherapeutic agents ?
