Transcription profiling of mouse GPI-deficient bone marrow cells in a mouse model of targeted Pig-a deletion

ABSTRACT: Somatic mutation in the X-linked phosphatidylinositol glycan class A (PIG-A) gene causes glycosylphosphatidylinositol (GPI) anchor deficiency in humans with Paroxysmal Nocturnal Hemoglobinuria (PNH). Clinically, patients with PNH have intravascular hemolysis, venous thrombosis and bone marrow failure. We produced a conditional Pig-a knock-out mouse model specifically inactivating the Pig-a gene in hematopoietic cells to study the role of PIG-A deficiency in PNH pathophysiology. We used Affymetrix Mouse Genome 430 2.0 chips to investigate the gene expression pattern in the mouse model of targeted Pig-a deletion. Experiment Overall Design: We performed microarray analysis on 3 pools of sorted GPI-deficient (GPI-) and GPI normal (GPI+) bone marrow cells derived from the same Pig-a knock-out a
