(Submitter supplied) TCL1 is an an oncogene and transgenic (Tg) mice expressing TCL1 specifically in B-cells are well-characterized models for chronic lymphocytic leukemia. On the contrary, PTPROt is a phosphatase with tumor suppressor characteristics in many cancers including leukemia. Our hypothesis was that transgenic expression of PTPROt in the B-cells of TCL1 Tg mice will alleviate disease phenotype and allow the study of the in vivo mechanism of action of PTPROt. more...

(Submitter supplied) Aberrant CXCR4 activity has been implicated in lymphoma pathogenesis, disease progression and resistance to therapies. Using a mouse model with a gain-of-function CXCR4 mutation (CXCR4C1013G) that hyperactivates CXCR4 signaling, we identified CXCR4 as a crucial activator of multiple key oncogenic pathways. CXCR4 hyperactivation furthermore resulted in an expansion of transitional B1 lymphocytes, which represent the precursors of chronic lymphocytic leukemia (CLL). more...

(Submitter supplied) The function of ID4 in CLL development was studied in vivo using TCL1 transgenic mouse model that develop leukemia similar to human CLL. TCL1 mice with ID4 single knockout gene have accelerated CLL progression. Results from the animal study suggest ID4 as a tumor suppressor gene that might regulate cell proliferation and apoptosis in B lymphocytes.

(Submitter supplied) Transcriptome analysis of RNA samples from leukemia cells of ROR1xTCL1 and TCL1 transgenic mice Animals engrafted with ROR1xTCL1 leukemia-cells developed more aggressive disease than mice engrafted with TCL1 leukemia cells. Transcriptome analysis of RNA samples from leukemia ROR1xTCL1 transgenic mice revealed shared common gene expression signatures that were distinct from those of TCL1 leukemia-cells.

(Submitter supplied) B-cell chronic lymphocytic leukemia (B-CLL) is a heterogenous disease with a highly variable clinical course and analysis of ZAP-70 and CD38 expression on B-CLL cells allowed for identification of patients with good (ZAP-70-CD38-), intermediate (discordant expression of ZAP-70 and CD38) and poor (ZAP-70+CD38+) prognosis. In an attempt to identify a molecular basis that may underly this diverse clinical behaviour DNA microarray technology was employed to compare eight ZAP-70+CD38+ with eight ZAP-70-CD38- B-CLL cases. more...

Analysis of B-cell chronic lymphocytic leukemia (B-CLL) cells that express or do not express zeta-associated protein (ZAP-70) and CD38. The prognosis of patients with ZAP-70-CD38- B-CLL cells is good, those with ZAP-70+CD38+ B-CLL cells is poor.

(Submitter supplied) FoxM1, a mammalian Forkhead Box M1 protein, is known as a typical proliferation-associated transcription factor that regulates of G1/S and G2/M transition in the proliferating cells. However, the in vivo function of FoxM1 in adult stem cells remains unknown. Here, we found that FoxM1 is highly expressed in hematopoietic stem cells (HSCs) and is essential for maintaining quiescence and self-renewal of HSCs in vivo. more...

(Submitter supplied) In the marrow and lymphatic tissues, chronic lymphocytic leukemia (CLL) cells interact with accessory cells that constitute the leukemia microenvironment. In lymphatic tissues, CLL cells are interspersed with CD68+ nurselike cells (NLC) and T cells. However, the mechanism regulating co-localization of CLL cells and these accessory cells are largely unknown. To dissect the molecular cross-talk between CLL and NLC, we profiled the gene expression of CD19-purified CLL cells before and after co-culture with NLC. more...

(Submitter supplied) Deletion of the short arm of chromosome 17 (17p-) is one of the most critical genetic variants used in B-CLL risk stratification. The tumor suppressor TP53 maps to this region, and its loss or mutation significantly accelerates B-CLL progression, hampers response to chemotherapy, and shortens survival. While florescent in situ hybridization (FISH) analyses for 17p deletions are routinely performed during clinical diagnoses, mutational analyses of the TP53 gene is not widely available and thus its mutational status is often unknown in patients with CLL. more...

(Submitter supplied) B cell chronic lymphocytic leukemia (CLL) is often preceded by a benign monoclonal or oligoclonal CD5+ B cell lymphocytosis. We have generated transgenic mice expressing a catalytically inactive, dominant-negative recombination activating gene 1 (dnRAG1 mice) in the periphery. These animals develop an early-onset indolent CD5+ B cell lymphocytosis, caused in part by a defect in secondary V(D)J rearrangements initiated to alter autoreactive B cell receptor specificity. more...

(Submitter supplied) Mutations of the tumor suppressor p53 lead to chemotherapy resistance and a dismal prognosis in chronic lymphocytic leukemia (CLL). Comparing miRNA/non-coding RNA expression profiles between p53 wild-type and p53 mutant samples in response to DNA damage, we exploit the impaired transcriptional activity of mutant p53 to map out p53 targets in primary CLL by small RNA sequencing. Focusing on miRNAs, we identify a set of p53-dependent miRNAs (miR-182-5p, miR-7-5p, miR-320c/d) in addition to the key p53 target miR-34a. more...

(Submitter supplied) Immune deficiency is common in cancer, but the biological basis for this and ways to reverse it remains elusive. Here we present a mouse model of B cell chronic lymphocytic leukemia (CLL) that recapitulates changes in the non-malignant circulating T cells seen in patients with this illness.1 To validate this model, we examined changes in T cell gene expression, protein expression and function in Em-TCL1 transgenic mice as they developed CLL 2,3 and demonstrate that development of CLL in these transgenic mice is associated with changes in impaired T cell function and in gene expression in CD4 and CD8 T cells similar to those observed in patients with this disease. more...

(Submitter supplied) Chronic Lymphocytic Leukaemia (CLL) is the most common leukemia in adults in the Western world. B cell receptor (BCR) signalling is known to be crucial for the pathogenesis and maintenance of CLL cells develop from mature CD5+ B cells. BCR signalling is regulated by the inhibitory co-receptor Siglec-G and Siglec-G-deficient mice have an enlarged CD5+ B1a cell population. Here, we determine how Siglec-G expression influences the severity of CLL.

Whole exome sequencing has identified hot-spot somatic XPO1 point mutations which we found to disrupt highly conserved biophysical interactions in the NES-binding groove, conferring novel cargo-binding abilities and forcing cellular mis-localization of critical regulators. more...
