Project description:We analysed the impact of single nucleotide polymorphisms (SNPs) in drug transporter genes on the molecular response to imatinib, using 857 SNPs covering 94 drug transporter genes on 355 chronic phase chronic myeloid leukemia (CP-CML) patients.
Project description:Arrays were used to determine the copy numbers of genomic regions harboring gene mutations and to identify heterozygous single nucleotide polymorphisms (SNPs) that were located close to these gene mutations. The gene mutations were identified through the COSMIC database and sequencing. The SNPs were used as control in single cell genetic analyses.
Project description:A core task to understand the consequences of non-coding single nucleotide polymorphisms (SNP) is to identify their genotype specific binding of transcription factor (TF). Here, we generate a large-scale TF-SNP interaction map for a selection of 116 colorectal cancer (CRC) risk loci and validated TF binding to 10 putatively functional SNPs. Our data further revealed TF binding complexity adjacent to the 116 risk loci, adding an additional layer of understanding to regulatory networks associated with CRC relevant loci.
Project description:This study aimed to evaluate the genomic effects of single nucleotide polymorphisms (SNPs) at the 9p21 locus that are clinically correlated with heart disease. We performed ATAC sequencing on iPSC-derived cardiac fibroblasts and found large differences in AP-1 and GATA family motifs between cells containing the SNPs and those lacking them.
Project description:Body weight (BW) is a critical economic trait for meat production in sheep. The current study aimed to perform a genome-wide association study (GWAS) to detect significant single-nucleotide polymorphisms (SNPs) that are associated with BW in Hu sheep.
Project description:The majority of single nucleotide polymorphisms (SNPs) associated with insulin resistance (IR)-relevant phenotypes by genome-wide association studies (GWASs) are located in noncoding regions, complicating their functional interpretation. Here, we utilized an adapted STARR-seq to systematically detect regulatory activity of 5,987 noncoding GWASs SNPs in three IR-relevant cell lines. We identified 876 SNPs with biased allelic enhancer activity across 133 loci, and further uncovered the genetic regulatory mechanisms underlying functional SNPs through integrating multi-omics analyses.
Project description:Short title: Innate Gene/miRNA MDP-response in CD RNA-seq and small RNA-seq were used to identify the expression of gene and microRNA (miRNA) in monocytes from healthy controls and patients with Crohn's Disease (CD), with and without NOD2 (nucleotide-binding oligomerization domain-containing protein 2) single nucleotide polymorphisms (SNPs) after stimulation with muramyl dipeptide (MDP).
Project description:Previously, cooperative binding to DNA between the bZIP domain of CREB1 and the ETS domain of GABPα was observed for the composite ETS-CRE motif (A0C1C2G3G4A5A6G7T8G9A10C11G12T13C14A15). Single nucleotide polymorphisms (SNPs) at the beginning and end of the ETS motif (ACCGGAAGT) increased cooperative binding. Here, we use a microarray containing all double nucleotide polymorphisms (DNPs) of the ETS-CRE motif to explore GABPα and CREB1 binding to their canonical motifs and their cooperative binding to the ETS-CRE motif. For GABPα, binding to SNPs predicted binding the DNPs. In contrast, CREB1 binding to DNPs showed cooperativity. Similar results were observed for other ETS and bZIP family members. Cooperative binding between GABPα and CREB1 was typically weaker than expected except for DNPs containing A7 and SNPs at the beginning of the ETS motif.
Project description:ApoC-III is a proatherogenic protein associated with elevated triglycerides; its deficiency is associated with reduced atherosclerosis. Mixed dyslipidemia, characterized by elevated triglyceride and apoC-III levels and low HDL cholesterol level, with or without elevated LDL cholesterol, increases cardiovascular disease risk and is commonly treated with combined statin and fibrate therapy. We sought to identify single nucleotide polymorphisms (SNPs) associated with apoC-III level response to combination therapy with statins and fenofibric acid (FA) in individuals with mixed dyslipidemia. Participants in a multicenter, randomized, double-blind, active-controlled study examining response to FA alone and in combination with statin were genotyped for candidate SNPs. Association between genotyed SNPs and APOC3 response to therapy was conducted We sought to identify single nucleotide polymorphisms (SNPs) associated with apoC-III level response to combination therapy with statins and fenofibric acid (FA) in individuals with mixed dyslipidemia. Participants in a multicenter, randomized, double-blind, active-controlled study examining response to FA alone and in combination with statin were genotyped for candidate SNPs. Genomic DNA extracted from peripheral blood was genotyped using a custom GoldenGate bead array encompassing 384 SNPs (Illumina). Multivariate linear regression and 2-way ANOVA for percent change in apoC-III level were performed between the groups receiving FA alone compared with FA+statin compared with statin alone.
