Gene expression profiles (stroma and epithelium) of prostate cancer mouse models (JOCK1, Pro-Cat × JOCK1, Ubi-Cat × JOCK1)

ABSTRACT: The fibroblast growth factor receptor (FGFR) and canonical Wnt signaling pathways are important regulators of carcinogenesis; however, the interaction between these two pathways in the context of prostate cancer (PCa) has not been fully elucidated. Using novel transgenic mouse models, we describe Wnt-induced synergistic acceleration of FGFR1-driven adenocarcinoma; largely due to pronounced fibroblastic reactive stroma (RS) activation surrounding prostatic intraepithelial neoplasia (PIN) lesions in endogenous and reconstitution assays. Finally, both mouse and human RS are characterized by increases in TGF-β signaling heterogeneity immediately adjacent to PIN lesions; however, heterogeneity is lost during later stages of progression, likely contributing to tissue invasion. These studies confirm the importance of the FGFR1-Wnt-TGF-β signaling axes as driving forces behind reactive stroma and aggressive adenocarcinoma.

Gene expression profiles (stroma and epithelium) of prostate cancer mouse models (JOCK1, Pro-Cat M-CM-^W JOCK1, Ubi-Cat M-CM-^W JOCK1)

Project description:The fibroblast growth factor receptor (FGFR) and canonical Wnt signaling pathways are important regulators of carcinogenesis; however, the interaction between these two pathways in the context of prostate cancer (PCa) has not been fully elucidated. Using novel transgenic mouse models, we describe Wnt-induced synergistic acceleration of FGFR1-driven adenocarcinoma; largely due to pronounced fibroblastic reactive stroma (RS) activation surrounding prostatic intraepithelial neoplasia (PIN) lesions in endogenous and reconstitution assays. Finally, both mouse and human RS are characterized by increases in TGF-M-NM-2 signaling heterogeneity immediately adjacent to PIN lesions; however, heterogeneity is lost during later stages of progression, likely contributing to tissue invasion. These studies confirm the importance of the FGFR1-Wnt-TGF-M-NM-2 signaling axes as driving forces behind reactive stroma and aggressive adenocarcinoma. To elucidate the mechanism behind the Wnt-accelerated FGFR1 adenocarcinoma, we performed laser capture microdissection (LCM) to separate pre-cancerous (hyperplasia and PIN) epithelia and adjacent reactive-stroma cells. We utilized frozen samples from specific time points (JOCK1, 40 weeks, Pro-Cat M-CM-^W JOCK1 and Ubi-Cat M-CM-^W JOCK1, 24 weeks) and performed gene expression profiling on the respective tissues.

Microarray analysis of PIN lesions from APT121 mouse prostate

Project description:High grade prostate intraepithelial neoplasia (HGPIN) is a precursor lesion for prostate cancer. The APT121 mouse is a model of early stage prostate cancer that develops PIN lesions that progress to adenocarcinoma over a period of 6 months. At 12 wks of age APT121 mouse prostate contains mostly high grade PIN lesions. We compared the transcript profile of RNA from the anterior prostate of age- and genetic background matched wild type and APT121 mice using Affymetric microarrays.

The contribution of FGFR1 to the development of SCLC is dictated by the cell-of-origin

Project description:Enhanced RAF/MEK/ERK signaling plays an obligatory role in many different types of cancer. Although genetic lesions promoting its aberrant activation are found in lung adenocarcinoma (LADC), the biological role of this pathway is not well documented in small cell lung cancer (SCLC). Here we explored the role of this pathway in SCLC and the broader class of tumors with neuroendocrine (NE) differentiation by introducing a constitutively active form of Fibroblast growth factor receptor 1 (Fgfr1) together with biallelic inactivation of Rb1 and Trp53 in mouse lung. Our data show that FGFR1 expression primarily results in LADC but also in NE tumors depending on the cell-of-origin. FGFR1 activation selectively promoted NE bronchial lesions in a novel lung cell subpopulation, whereas it impaired progression of typical central SCLC initiated from CGRP-expressing NE cells, which is believed to be the most prominent cell-of-origin of SCLC. Strikingly, FGFR1 activation was well tolerated by K14-expressing cells that were efficiently transformed into SCLC and other NE lesions. Taken together, our results indicate that FGFR1 can serve either as driver or suppressor of distinct lung cancer subtypes depending on the cell-of-origin, which should be taken into account when considering FGFR1 as a therapeutic target.

Genomic profiling of Richter-syndrome Chronic Lymphocytic Leukemia

Project description:Richter syndrome (RS) occurs in up to 15% of patients with chronic lymphocytic leukemia (CLL). While RS, usually represented by the histologic transformation to a diffuse large B-cell lymphoma (DLBCL), is associated with a very poor outcome, especially when clonally related to the pre-existing CLL, mechanisms leading to RS have not been clarified yet. To better understand the pathogenesis of RS, we analyzed a series of cases including: 59 RS, 28 CLL-phase of RS, 315 CLL and 127 de novo DLBCL. RS demonstrated a genomic complexity intermediate between CLL and DLBCL. Cell cycle deregulation via inactivation of TP53 and of CDKN2A was a main mechanism in the histologic transformation from CLL-phase, being present in approximately half of the cases, and affected the outcome of the RS patients. A second major subgroup was characterized by the presence of trisomy 12 and comprised one third of the cases. While RS shared some of the lesions seen in de novo DLBCL, its genomic profile was clearly separate. The CLL-phase preceding RS had not a generalized increase in genomic complexity when compared with untransformed CLL, but it presented clear differences in the frequency of specific genetic lesions.

Genomic Landscape and Therapeutic Targets of Adenosquamous Carcinoma of the Pancreas [CGH Microarray]

Project description:We applied DNA content flow cytometry to a series of adenosquamous cancer of the pancreas (ASCP) tumor samples and patient derived xenografts (PDXs). We interrogated purified sorted tumor fractions from each sample with whole genome copy number variant (CNV) and whole exome sequencing (WES) analyses. These identified a variety of somatic genomic lesions targeting chromatin regulators in ASCP genomes that were superimposed on well characterized genomic lesions including mutations in KRAS and TP53, homozygous deletion of CDKN2A, and amplification of c-MYC, that are common in PDACs. Furthermore, a comparison of ATAC-seq profiles of ASCP and pancreatic ductal adenocarcinoma (PDAC) genomes using flow sorted PDX models distinguished genes with accessible chromatin in ASCP genomes including the lysine methyltransferase SMYD2, the pancreatic cancer stem cell driver RORγ, and a FGFR1-ERLIN2 fusion associated with focal CNVs in both genes. Organoids derived from these models were used to screen compounds of interest. Notably a FGFR inhibitor had significant activity against the FGFR1-ERLIN2 fusion positive PDX.
