To understand the underlying mechanism by which the Hif1a gene is required by hematopoietic stem cells (HSCs), we performed a comparative DNA microarray analysis using total RNA isolated from wild type Lin-Sca-1+c-Kit+ cells and Hif1a-/- Lin-Sca-1+c-Kit+ cells. The result was validated by quantitati...
Using a mouse model of chronic myelogenous leukemia (CML), here we report that HIF1M-NM-1 plays a crucial role in survival maintenance of leukemia stem cells (LSCs). Deletion of HIF1M-NM-1 impairs the propagation of CML through impairing cell cycle progression and inducing apoptosis of LSCs. Deletio...
Using BCR-ABL-induced chronic myeloid leukemia (CML) as a disease model for leukemia stem cells (LSCs), we showed that BCR-ABL down-regulates the B lymphoid kinase (Blk) gene in leukemia stem cells in CML mice and that Blk functions as a tumor suppressor in LSCs and suppresses LSC function. Inhibiti...
Chaperone-mediated autophagy (CMA) acting as a crucial, selective protein degradation pathway is a key topic in understanding tissue remodeling and disease, with recent research showing its pivotal role in maintaining organ health, particularly through the maintenance of fibroblast quiescence and su...
We performed affinity purification of PRRX1 using cells expressing Flag tagged PRRX1 isoforms - PRRX1A or PRRX1B, and carried out mass spectrometry (AP-MS) analysis.
