Bernard G Forget MD

Professor Emeritus of Medicine (Hematology) and Professor of Genetics and of Medicine (Hematology)

Research Interests

Molecular Genetics of Erythroid Cell Differentiation; Hematopoietic Stem Cell Biology

Research Summary

Dr. Forget's laboratory is involved in a research program studying the regulation of gene expression in hematopoietic cells, with an emphasis on erythroid-specific gene expression. Work is devoted to: study of the transcriptional regulation of genes encoding red cell membrane skeleton proteins such as spectrin and ankyrin; study of the molecular basis of mutations of these genes that cause hereditary anemias; and study of differential gene expression in highly enriched primitive hematopoietic stem cells. The study of the regulation of tissue-specific gene expression and hematopoietic stem cell-specific gene expression is relevant to the elucidation of mechanisms responsible for abnormal gene expression in genetic and acquired disorders of blood cells, and to research directed at the purification and manipulation of reconstituting hematopoietic stem cells for the purposes of gene therapy.

Extensive Research Description

Hematopoiesis provides an excellent model system for the study of gene expression and the molecular basis of disease. In hematopoietic cells, a number of genes are expressed in a tissue-specific and developmentally regulated fashion. Furthermore, a number of inherited and acquired disorders of hematopoietic cells are due to mutations that result in abnormal expression of these specialized genes.
