The characterization and targeting of Philadelphia chromosome positive (Ph(+)) acute lymphoblastic leukemia (ALL)-initiating cells remains unresolved. Expression of the polycomb protein Bmi1 is up-regulated in patients with advanced stages of chronic myelogenous leukemia (CML). We report that Bmi1 transforms and reprograms CML B-lymphoid progenitors into(More)
Krüppel-like factor 5 regulates pluripotent stem cell self-renewal, but its role in somatic stem cells is unknown. Here we show that Krüppel-like factor 5-deficient haematopoietic stem cells and progenitors fail to engraft after transplantation. This haematopoietic stem cell and progenitor defect is associated with impaired bone marrow homing and lodging(More)
Alterations within the renal renin angiotensin system play a pivotal role in the development and progression of cardiovascular and renal disease. Angiotensin converting enzyme 2 (ACE2) is highly expressed in renal tubules and has been shown to be renoprotective in diabetes. The protease, a disintegrin and metalloprotease (ADAM) 17, is involved in the(More)
Despite the introduction of tyrosine kinase inhibitor therapy, the prognosis for p190-BCR-ABL(+) acute lymphoblastic leukemia remains poor. In the present study, we present the cellular and molecular roles of the Rho GTPase guanine nucleotide exchange factor Vav in lymphoid leukemogenesis and explore the roles of Vav proteins in BCR-ABL-dependent signaling.(More)
BACKGROUND Efavirenz is the preferred nonnucleotide reverse transcriptase inhibitor for first-line antiretroviral treatment in many countries. It is orally active and is specific for human immunodeficiency virus type 1. Its effectiveness can be attributed to its long half-life, which is 52-76 h after multiple doses. The drug is having poor water solubility.(More)
