Kinome profiling of shControl and shFANCA THP1 cells treated with volasertib

ABSTRACT: The Fanconi anemia (FA) pathway is a network of proteins critical to the preservation of genomic integrity and the prevention of cancer. FA proteins safeguard the genome by regulating the cell cycle and facilitating error-free repair of DNA damage. Bi-allelic mutation of genes encoding FA pathway proteins causes the cancer predisposition syndrome Fanconi anemia (FA), which is associated with a high incidence of acute myeloid leukemia (AML). Individuals with mono-allelic mutation of a subset FA genes do not develop FA but suffer increased lifetime risk of solid and hematological malignancies. Within the general population, approximately 14% of sporadic AMLs harbor damaging mutations within the FA pathway. Our previous work demonstrated that inhibition of the mitotic kinase PLK1 induced synthetic lethality in cells deficient for FANCA, the gene most frequently lost in FA. This finding corroborates work from others that have identified synthetic lethal interactions between PLK1 and additional FA genes (FANCG, BRCA1, and BRCA2). Together, these findings suggest that FA pathway mutations may serve as biomarkers for sensitivity to PLK1 inhibitors, which have demonstrated therapeutic efficacy in an undefined subset of AML patients. Here, THP1 AML cells were generated with shControl or shFANCA and treated with 10nM volasertib for 24 h prior to kinome profiling.

Transcription profiling of human bone marrow cells from normal volunteers and from children and adults with Fanconi anemia

Project description:Fanconi anemia (FA) is a rare inherited disease complicated by aplastic anemia. There is evidence that hematopoietic stem cells have lost self replicative capacity and undergo apoptosis when exposed to inhibitory cytokines including interferon gamma and tumor necrosis factor-alpha. We used gene expression microarrays to identify transcriptomal differences between bone marrow cells from normal volunteers and from children and adults with Fanconi anemia Experiment Overall Design: Fanconi anemia patients were identified using mitomycin C and/or diepoxybutane chromosomal breakage analysis. Eleven normal volunteers and 21 FA patients were studied. All FA patients with cytogenetic evidence of clonal evolution were excluded. All FA patients with acute leukemia were excluded. RNA was prepared from freshly obtained low density mononuclear cell fractions.

Effect of oxygen tension on MMTV-PyMT tumor cell kinome

Project description:Solid tumors are characterized by significantly lower oxygen (O2) levels. Despite this fact, routine preclinical cancer studies are performed under ambient O2 conditions. We have developed an experimental approach that allows us to collect, process and evaluate cancer and non-cancer cells under physioxia (3-5% O2), in such a way that there is very minimal exposure to air. We have shown in previous studies that ambient and physioxic O2 differentially impact relevant cell surface markers and sensitivity to therapy. In this study, our goal was to further explore oxygen-dependent signaling pathway alterations and to determine how these pathways influence response to targeted therapies. Using cells derived from transgenic mouse mammary tumors and healthy primary human breast epithelial cells, we show the impact of ambient air and physioxia on the kinome, with subsequent pathway alterations that mediate the effectiveness of single and combination therapies. Our data emphasize the importance of O2 considerations in preclinical cancer research and drug development.

Determining the KRAS-regulated kinome in PDAC

Project description:Oncogenic KRAS drives cancer growth by activating diverse signaling networks, not all of which have been fully delineated. We set out to establish a system-wide profile of the KRAS-regulated kinase signaling network (kinome) in KRAS-mutant pancreatic ductal adenocarcinoma (PDAC). We knocked down KRAS expression in a panel of six cell lines, and then applied Multiplexed Inhibitor Bead/Mass Spectrometry (MIB/MS) chemical proteomics to monitor changes in kinase activity and/or expression. We hypothesized that depletion of KRAS would result in downregulation of kinases required for KRAS-mediated transforming activities, and in upregulation of other kinases that could potentially compensate for the deleterious consequences of the loss of KRAS. We identified 15 upregulated and 13 downregulated kinases in common across the panel. In agreement with our hypothesis, all 15 of the upregulated kinases have established roles as cancer drivers (e.g., SRC, TGFBR1, ILK), and pharmacologic inhibition of the upregulated kinase, DDR1, suppressed PDAC growth. Interestingly, 11 of the 13 downregulated kinases have established driver roles in cell cycle progression, particularly in mitosis (e.g., WEE1, Aurora A, PLK1). Consistent with a crucial role for the downregulated kinases in promoting KRAS-driven proliferation, we found that pharmacologic inhibition of WEE1 also suppressed PDAC growth. The unexpected paradoxical activation of ERK upon WEE1 inhibition led us to inhibit both WEE1 and ERK concurrently, which caused further potent growth suppression and enhanced apoptotic death than WEE1 inhibition alone. We conclude that system-wide delineation of the KRAS-regulated kinome can identify potential therapeutic targets for KRAS-mutant pancreatic cancer.

Transcriptional silencing of ALDH2 confers a dependency on Fanconi anemia proteins in acute myeloid leukemia

Project description:With domain focused CRISPR screen, we revealed Fanconi anemia (FA) proteins UBE2T (an E2) and FANCL (an E3) as unique dependencies in AML. We demonstrate that these dependencies are due to a synthetic lethal interaction between FA proteins and Aldehyde Dehydrogenase 2 (ALDH2), which function in parallel pathways to counteract the genotoxic effects of endogenous aldehydes. We provide evidence that DNA hypermethylation and transcriptional silencing of ALDH2 occur in a recurrent manner in human AML patient samples, which is sufficient to confer FA pathway dependency in this disease. Taken together, our study suggests that targeting of the ubiquitination reaction catalyzed by FA proteins can eliminate ALDH2-deficient AML.

Global gene expression analysis for neuron stem cells (NSC) derived from iPSCs with Fanconi Anemia

Project description:Fanconi Anemia (FA) is a recessive disorder associated with genomic instability We generated iPSC from FA patient fibroblasts and further corrected the mutated FANCA gene with a homologous recombination-based approach. The NSCs were differentiated from control-iPSCs, FA-iPSCs, and corrected FA-NSCs, and their gene expressions were determined by microarray analysis.

In Fanconi Anemia, impaired accumulation of bone marrow neutrophils during emergency granulopoiesis induces hematopoietic stem cell stress

Project description:Fanconi Anemia (FA) is an inherited disorder of DNA-repair caused by mutation in one of 20+ interrelated genes that repair intra-strand DNA crosslinks and rescue collapsed or stalled replication forks. The most common hematologic abnormality in FA is anemia, but progression to bone marrow failure (BMF), clonal hematopoiesis, or acute myeloid leukemia (AML) may also occur. In prior studies, we found that Fanconi DNA-repair is required for successful emergency granulopoiesis; the process for rapid neutrophil production during the innate immune response. Specifically, Fancc-/- mice did not develop neutrophilia in response to emergency granulopoiesis stimuli, but instead exhibited apoptosis of bone marrow hematopoietic stem cells (HSCs) and differentiating neutrophils. Repeated emergency granulopoiesis challenges induced BMF in most Fancc-/- mice, with AML in survivors. In contrast, we found equivalent emergency granulopoiesis-induced neutrophilia in Fancc-/-Tp53+/- mice and wild type (WT) mice, without BMF in either. Since bone marrow neutrophil accumulation triggers termination of emergency granulopoiesis, we hypothesize neutrophilia protects Fancc-/-Tp53+/- bone marrow from the stress of sustained inflammatory physiology, as experienced by Fancc-/- mice.
