Description of Clinical Expertise

Acute and Chronic Myeloid Malignancies

Description of Research Expertise

The Paralkar Lab studies how genes regulating ribosome biogenesis guide normal hematopoiesis, and how mutations in these genes lead to acute or chronic myeloid leukemias.

Hematopoiesis, Leukemia, Gene regulation, Ribosome biogenesis, Stem cells

Hematopoiesis is a complex and highly regulated process by which stem cells residing in bone marrow produce a constant stream of blood cells to preserve a functional hematopoietic system throughout the duration of a human lifespan. Mutations in epigenetic regulators, transcription factors, splicing proteins and tumor suppressors can derange the normal course of hematopoiesis, and lead to clonal expansion and leukemia. Several mutated proteins also regulate ribosomal biogenesis. Normal ribosomal function is crucial for hematopoiesis, and dysfunction can either lead to bone marrow failure or myeloproliferation. The mechanisms by which most of these mutated genes produce malignancy remain poorly understood.

In the Paralkar Lab, we apply state-of-the art molecular biology techniques to in vitro and in vivo models of hematopoiesis and leukemia to study normal blood development and the mechanisms of leukemogenesis, and gain insight into the delicate balance between normal differentiation and malignancy.
