Abstract
Patients with heart failure (HF) often experience repeated acute decompensation and develop comorbidities such as chronic kidney disease and frailty syndrome. Although this suggests pathological interaction among comorbidities, the mechanisms linking them are poorly understood. Here, we identified alterations in hematopoietic stem cells (HSCs) as a critical driver of recurrent HF and associated comorbidities. Bone marrow transplantation from HF-experienced mice resulted in spontaneous cardiac dysfunction and fibrosis in recipient mice, as well as increased vulnerability to kidney and skeletal muscle insults. HF enhanced the capacity of HSCs to generate proinflammatory macrophages. In HF mice, global chromatin accessibility analysis and single-cell RNA-seq showed that transforming growth factor-β (TGF-β) signaling was suppressed in HSCs, which corresponded with repressed sympathetic nervous activity in bone marrow. Transplantation of bone marrow from mice in which TGF-β signaling was inhibited similarly exacerbated cardiac dysfunction. Collectively, these results suggest that cardiac stress modulates the epigenome of HSCs, which in turn alters their capacity to generate cardiac macrophage subpopulations. This change in HSCs may be a common driver of repeated HF events and comorbidity by serving as a key carrier of "stress memory."

Abstract
Philadelphia chromosome-like acute lymphoblastic leukemia (Ph-like ALL) is a high-risk subtype of B-ALL often associated with genetic variants that alter cytokine receptor signaling, including mutations in the interleukin-7 receptor (IL7R). To investigate whether IL7R variants are leukemia-initiating, we built mouse models expressing activated Il7r (aIL7R). B-cell intrinsic aIL7R mice developed spontaneous B-ALL, demonstrating sufficiency of Il7r activating mutations in leukemogenesis. Concomitant introduction of a knock-out allele in the associated adapter protein Lnk (encoded by Sh2b3) or a dominant-negative variant of the transcription factor Ikaros (Ikzf1) increased disease penetrance. The resulting murine leukemias displayed monoclonality and recurrent somatic Kras mutations and efficiently engrafted into immunocompetent mice. Phosphoproteomic analyses of aIL7R leukemic cells revealed constitutive Stat5 signaling and B cell receptor (BCR)-like signaling despite the absence of surface pre-BCR. Finally, in vitro treatment of aIL7R leukemic B-cells with Jak, mTOR, or Syk inhibitors blocked growth, confirming that each pathway is active in this mouse model of IL7R-driven B-ALL.

Mutant Idh2 Cooperates with a NUP98-HOXD13 Fusion to Induce Early Immature Thymocyte Precursor ALL. Cancer Res 2021; 81:5033-5046.

Abstract
Mutations in the isocitrate dehydrogenase 1 (IDH1) and IDH2 genes are frequently observed in a wide variety of hematologic malignancies, including myeloid and T-cell leukemias. In this study, we generated Idh2R140Q transgenic mice to examine the role of the Idh2R140Q mutation in leukemia. No leukemia developed in Idh2R140Q transgenic mice, suggesting a need for additional genetic events for leukemia development. Because myeloid cells from NUP98-HOXD13 fusion (NHD13) transgenic mice frequently acquire somatic Idh mutations when they transform to acute myeloid leukemia, we generated Idh2R140Q/NHD13 double transgenic mice. Idh2R140Q/NHD13 transgenic mice developed an immature T-cell leukemia with an immunophenotype similar to double-negative 1 (DN1) or DN2 thymocytes. Idh2R140Q/NHD13 leukemic cells were enriched for an early thymic precursor transcriptional signature, and the gene expression profile for Idh2R140Q/NHD13 DN1/DN2 T-ALL closely matched that of human early/immature T-cell precursor (EITP) acute lymphoblastic leukemia (ALL). Moreover, recurrent mutations found in patients with EITP ALL, including KRAS, PTPN11, JAK3, SH2B3, and EZH2 were also found in Idh2R140Q/NHD13 DN1/DN2 T-ALL. In vitro treatment of Idh2R140Q/NHD13 thymocytes with enasidenib, a selective inhibitor of mutant IDH2, led to a marked decrease in leukemic cell proliferation. These findings demonstrate that Idh2R140Q/NHD13 mice can serve as a useful in vivo model for the study of early/immature thymocyte precursor acute lymphoblastic leukemia development and therapy. SIGNIFICANCE: T-cell leukemia induced in Idh2R140Q/NUP98-HOXD13 mice is immunophenotypically, transcriptionally, and genetically similar to human EITP ALL, providing a model for studying disease development and treatment.

Abstract
Mice homozygous for a hypomorphic allele of DNA replication factor minichromosome maintenance protein 2 (designated Mcm2cre/cre) develop precursor T cell lymphoblastic leukemia/lymphoma (pre-T LBL) with 4-32 small interstitial deletions per tumor. Mice that express a NUP98-HOXD13 (NHD13) transgene develop multiple types of leukemia, including myeloid and T and B lymphocyte. All Mcm2cre/cre NHD13+ mice develop pre-T LBL, and 26% develop an unrelated, concurrent B cell precursor acute lymphoblastic leukemia (BCP-ALL). Copy number alteration (CNA) analysis demonstrated that pre-T LBLs were characterized by homozygous deletions of Pten and Tcf3 and partial deletions of Notch1 leading to Notch1 activation. In contrast, BCP-ALLs were characterized by recurrent deletions involving Pax5 and Ptpn1 and copy number gain of Abl1 and Nup214 resulting in a Nup214-Abl1 fusion. We present a model in which Mcm2 deficiency leads to replicative stress, DNA double strand breaks (DSBs), and resultant CNAs due to errors in DNA DSB repair. CNAs that involve critical oncogenic pathways are then selected in vivo as malignant lymphoblasts because of a fitness advantage. Some CNAs, such as those involving Abl1 and Notch1, represent attractive targets for therapy.

Abstract
Objective: To report the rate of candidate actionable somatic mutations in patients with locally advanced and metastatic gastro-enteropancreatic (GEP) neuroendocrine tumors (NET) and of other genetic alterations that may be associated with tumorigenesis. Methods: A phase II mutation targeted therapy trial was conducted in patients with advanced well-differentiated G1/G2 GEP-NET. Mutations found in the mTOR pathway-associated genes led to treatment with the mTOR inhibitor everolimus, and were defined as actionable. Tumor deoxyribonucleic acid (DNA) from GEP-NET were sequenced and compared with germline DNA, using the OncoVAR-NET assay, designed for hybrid capture sequencing of 500 tumor suppressor genes and oncogenes. Somatic variants were called and copy-number (CN) variant analysis was performed. Results: Thirty patients (14 small-intestine, 8 pancreatic, 3 unknown primary NET, and 5 of other primary sites) harbored 37 lesions (4 patients had DNA of multiple lesions sequenced). Only 2 patients with sporadic NET (n = 26) had an actionable mutation leading to treatment with everolimus. Driver somatic mutations were detected in 18 of 30 patients (21/37 lesions sequenced). In the remaining samples without a driver mutation, CN alterations were found in 11/16 tumors (10/12 patients), including CN loss of chromosome (Chr) 18 (P<.05), CN gain of Chr 5, and loss of Chr 13. CN losses in Chr 18 were more common in patients without driver mutations detected. Pronounced genetic heterogeneity was detected in patients with multiple lesions sequenced. Conclusion: Genome-wide DNA sequencing may identify candidate actionable genes and lead to the identification of novel target genes for advanced well-differentiated GEP-NET. Abbreviations: Chr = chromosome; CN = copy number; DNA = deoxyribonucleic acid; FDA = Food and Drug Administration; GEP = gastro-enteropancreatic; MEN-1 = multiple endocrine neoplasia syndrome type 1; mTOR = mammalian target of rapamycin; NET = neuroendocrine tumor; PFS = progression-free survival; PNET = pancreatic neuroendocrine tumors; SINET = small-intestine neuroendocrine tumor.

Abstract
The TCL1 mouse model is widely used to study pathophysiology, clonal evolution, and drug sensitivity or resistance of chronic lymphocytic leukemia (CLL). By performing whole exome sequencing, we present the genetic landscape of primary tumors from TCL1 mice and of TCL1 tumors serially transplanted into wild-type recipients to mimic clonal evolution. We show that similar to CLL patients, mutations in mice are frequently subclonal and heterogenous among different primary TCL1 mice. We further describe that this molecular heterogeneity mirrors heterogenous disease characteristics such as organ infiltration or CLL dependent T cell skewing. Similar to human CLL, we further observed the occurrence of novel mutations and structural variations during clonal evolution and found plasticity in the expansion of B cell receptor specific subclones. Thus, our results uncover that the genetic complexity, pathway dependence and clonal dynamics in mouse CLL are in relevant agreement to human CLL, and they are important to consider in future research using the TCL1 mouse for studying CLL.

Abstract
B-1 and B-2 lymphocytes are derived from distinct developmental pathways and represent layered arms of the innate and adaptive immune systems, respectively. In contrast to a majority of murine B-cell malignancies, which stain positive with the B220 antibody, we discovered a novel form of B-cell leukemia in NUP98-PHF23 (NP23) transgenic mice. The immunophenotype (Lin- B220- CD19+ AA4.1+) was identical to that of progenitor (pro) B-1 cells, and VH gene usage was skewed toward 3' V regions, similar to murine fetal liver B cells. Moreover, the gene expression profile of these leukemias was most similar to that of fetal liver pro-B fraction BC, a known source of B-1 B cells, further supporting a pro-B-1 origin of these leukemias. The NP23 pro-B-1 acute lymphoblastic leukemias (ALLs) acquired spontaneous mutations in both Bcor and Janus kinase (Jak) pathway (Jak1/2/3 and Stat5a) genes, supporting a hypothesis that mutations in 3 critical pathways (stem-cell self-renewal, B-cell differentiation, and cytokine signaling) collaborate to induce B-cell precursor (BCP) ALL. Finally, the thymic stromal lymphopoietin (Tslp) cytokine is required for murine B-1 development, and chromosomal rearrangements resulting in overexpression of the TSLP receptor (CRLF2) are present in some patients with high-risk BCP-ALL (referred to as CRLF2r ALL). Gene expression profiles of NP23 pro-B-1 ALL were more similar to that of CRLF2r ALL than non-CRLF2r ALL, and analysis of VH gene usage from patients with CRLF2r ALL demonstrated preferential usage of VH regions used by human B-1 B cells, leading to the suggestion that this subset of patients with BCP-ALL has a malignancy of B-1, rather than B-2, B-cell origin.
