Description
Cardiac hypertrophy is an independent risk factor for cardiovascular disease and heart failure. There is increasing evidence that microRNAs (miRNAs) play an important role in the regulation of messenger RNA (mRNA) and the pathogenesis of various cardiovascular diseases. However, the ability to comprehensively study cardiac hypertrophy on a gene regulatory level is impacted by the limited availability of human cardiomyocytes. Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) offer the opportunity for disease modeling.

- Affymetrix HT HG-U133+ PM Array Plate (hthgu133pluspm)
Description
The post-transcriptional control of mRNA stability plays a critical role in numerous biological functions, including the immune response, cell cycle regulation and DNA damage response. HNRNPA0, which encodes an RNA-binding protein shown to regulate transcript stability via binding to the AU-rich elements (AREs) of mRNAs, is located within the commonly deleted segment of 5q31.2 in therapy-related myeloid neoplasms (t-MNs) with a del(5q). We hypothesized that loss of HNRNPA0 leads to alterations in hematopoietic differentiation due to changes in the expression of its target AU-rich transcripts. Using RNAi interference to model Hnrnpa0 loss in primary murine cells and an experimental cell system, we found that reduced Hnrnpa0 expression leads to a shift from monocytic towards granulocytic differentiation. Microarray-based global expression profiling revealed that Hnrnpa0 knockdown disproportionally impacts ARE-containing transcripts and alters expression of myeloid specification genes. The biological importance of ARE-containing genes in myeloid neoplasms is further supported by changes in gene expression of ARE-mRNAs in t-MN del(5q) patients, predicted by pathway analysis to activate tumor growth. Together, our findings suggest that alterations in ARE-containing genes can positively regulate the cellular proliferation of del(5q) cells and implicate haploinsufficiency of HNRNPA0 as one of the key initiation mutations in the pathogenesis of t-MN.

Description
Although cure rates for acute lymphoblastic leukemia (ALL) have increased, development of resistance to drugs and patient relapse are common. The environment in which the leukemia cells are present during the drug treatment is known to provide significant survival benefit. Here, we have modeled this process by culturing murine Bcr/Abl-positive acute lymphoblastic leukemia cells in the presence of stroma while treating them with a moderate dose of two unrelated drugs, the farnesyltransferase inhibitor lonafarnib and the tyrosine kinase inhibitor nilotinib. This results in an initial large reduction in cell viability of the culture and inhibition of cell proliferation. However, after a number of days, cell death ceases and the culture becomes drug-tolerant, enabling cell division to resume. We used gene expression profiling to analyze changes in the transcriptome of these leukemia cells over a 3-4 week period, taking samples at the start, the point at which most of the leukemia cells had been eradicated while a small percentage survived, and at the end when the cells were proliferating again.

Description
Primary pre-B acute lymphoblastic (ALL) cells do not proliferate long-term ex vivo without the presence of stromal support. We developed and use an ex vivo co-culture model, consisting of mouse leukemic pre-B Bcr/Abl-expressing ALL cells grown with mitotically inactivated mouse embryonic fibroblasts (MEFs). This system provides a generic type of environmentally-mediated protection to the ALL cells, because when the ALL cells are treated with a moderate dose of a therapeutic drug, drug-resistant ALL cells can be recovered after a 1-2 week period of culture. Some of the factors produced by stromal cells that provide protection to ALL cells have been identified. However, it is unclear if the presence of drug-treated ALL cells affects the stromal fibroblasts. The current study was initiated to examine this using expression profiling on the irradiated MEFs.
