Project description:Zebrafish populations recently collected from the wild differ from domesticated populations in anxiety-related behaviors. We measured anxiety-related behaviors in wild and domesticated zebrafish populations and performed a multi-brain region transcriptional comparison using microarrays to try to understand the genetic changes that accompany behavioral adaptation to domestication.

Project description:The ATP-dependent DExH/D-box helicase DHX9 is a key participant in a number of gene regulatory steps, including transcriptional, translational, microRNA-mediated control, DNA replication, and maintenance of genomic stability. DHX9 has also been implicated in maintenance of the tumorigenic process and in drug response. Here, we report that inhibition of DHX9 expression is lethal to multiple human and mouse cancer cell lines. In contrast, using a novel conditional shDHX9 mouse model, we demonstrate that sustained and prolonged suppression of DHX9 is well tolerated at the organismal level. Our results demonstrate a robust tolerance for DHX9 knockdown in non-transformed cells and supports the targeting of DHX9 as an effective and specific chemotherapeutic approach. Comparison of gene expression in large intestine of mice with or without reduced expression of DHX9.

Project description:Zebrafish populations recently collected from the wild differ from domesticated populations in anxiety-related behaviors. We measured anxiety-related behaviors in wild and domesticated zebrafish populations and performed a multi-brain region transcriptional comparison using microarrays to try to understand the genetic changes that accompany behavioral adaptation to domestication. We performed a microarray analysis comparing the midbrain and telencephalon brain regions of male and female adult zebrafish from four populations varying in domestication history (Wild: Nadia (N) and Pargana (P), and Domesticated: Scientific Hatchery (S) and Transgenic Mosaic 1 (T)). We collected 16 samples per brain region (4 samples per zebrafish population, with 1 telencephalon sample missing for the S population). We attempted to maintain equal sex ratios within each zebrafish population, but this was not always possible due to sex biases within some populations.

Project description:During development neuronal progenitors compete for growth factors such as nerve growth factor NGF and require the prolyl hydroxylase EglN3 and the kinesin KIF1Bβ for developmental apoptosis. Inherited KIF1Bβ loss-of-function mutations in neuroblastomas and pheochromocytomas implicate KIF1Bβ as a 1p36.2 tumor suppressor, however the mechanism of tumor suppression is unknown. We found that KIF1Bβ interacts with the RNA helicase A (DHX9) resulting in DHX9 nuclear accumulation to regulate apoptosis. KIF1Bβ-dependent DHX9 nuclear localization leads to transcription of the apoptotic target XIAP-associated factor 1. DHX9 is induced when NGF is limiting and required for apoptosis in cells deprived of NGF. NB1 cells were transduced to incorporate shRNA against DHX9 or a scrambled control, and transfected with a KIF1Bβ expression vector or control, then transfected cells were isolated and lysed after 48h.

Project description:Ctcf heterozygous knockout mice are susceptible to neoplasia in a broad range of tissues, including lymphoma, endometrial cancer, and non-small cell lung cancer. Retention of the wild type Ctcf allele in these tumors establishes CTCF as a haploinsufficient tumor suppressor gene. Both human tumors and normal murine tissues with CTCF disruption are characterized by genome-wide differences in DNA methylation relative to CTCF wild type tissues, indicating even modest disruption of CTCF broadly destabilizes DNA methylation in vivo. This cross species functional analysis identifies CTCF as a commonly mutated tumor suppressor gene and establishes a central role for DNA methylation stability in tumor suppression. RRBS sequencing of transgenic Ctcf heterozygous mice and wild-type litter mate whole lung tissue.

Project description:Condition specific zebrafish metabolic models generated using the COBRA MetaboTools framework. The Wang et al., (2021) zebrafish genome-scale metabolic model (GEM) was constrained with experimental data from 5 days post fertilized (dpf) zebrafish to generate a 'base-model'.
In turn this 5 dpf zebrafish base-model was constrained with experimental (transcriptomics and metabolomics) data from 5 dpf zebrafish exposed to the environmental pollutant perfluorooctane sulfonate (PFOS), at three levels - Low (0.06 uM), Medium (0.6 uM), and High (2 uM) PFOS.
The MetaboTools framework was used to construct three condition-sepcific models: Low, Medium, and High PFOS.
Key simulation predictions of effects on the carnitine shuttle and lipid metabolism were confirmed in wild-caught fish and dolphins (stranded animals) sampled from the northern Gulf of Mexico - published in Nolen et al., (2024) https://doi.org/10.1016/j.cbpc.2023.109817

Project description:LAP-35 and SK-N_MC cells were treated with 10 J/m2 UV light versus untreated Alternative pre-mRNA processing plays a key role in the response to DNA damage as well as in neoplastic transformation. We found that two Ewing Sarcoma (ES) cell lines exhibit different sensitivity to UV light irradiation, with SK-N-MC cells being more sensitive than LAP-35 cells. RNA profiling during the response to low doses of UV light irradiation revealed genes differentially regulated between the two cell lines. In particular, UV light irradiation induced a novel isoform of the RNA helicase DHX9 which is targeted to nonsense-mediated decay (NMD) and therefore causes down-regulation of DHX9 in SK-N-MC cells, but not in LAP-35 cells. DHX9 protein forms a complex with RNA polymerase II (RNAPII) and EWS-FLI1 to enhance transcription, and we found that down-regulation of DHX9 by UV light irradiation in SK-N-MC cells impairs the recruitment of EWS-FLI1 to target genes and increases sensitivity to DNA damage. Notably, sensitivity of SK-N-MC cells to irradiation correlated with enhanced phosphorylation and decreased processivity of RNAPII upon irradiation, which in turn causes inclusion of the novel DHX9 exon in SK-N-MC cells exposed to UV light, an observation that could be recapitulated in LAP35 cells by pharmacological reduction of RNAPII processivity. Our data suggest that EWS-FLI1 oncogene activity could be targeted by modulation of DHX9 gene expression. Three biological replicates were labeled in direct and dye-swap microarray experiments and hybridized onto an Agilent custom splicing-sensitive microarray platform
