Moreover, there have been very few reports on genetic markers associated with canine obesity. These studies were limited to the use of a single breed in the association study. In this study, we have performed a GWAS and supplemented it with gene-set enrichment and pathway-based analyses to identify causative loci and genes associated with canine obesity in 18 different dog breeds. From the GWAS, the significant markers associated with obesity-related traits including body weight (CACNA1B, C22orf39, U6, MYH14, PTPN2, SEH1L) and blood sugar (PRSS55, GRIK2), were identified. Furthermore, the gene-set enrichment and pathway-based analysis (GESA) highlighted five enriched pathways (Wnt signaling pathway, adherens junction, pathways in cancer, axon guidance, and insulin secretion) and seven GO terms (fat cell differentiation, calcium ion binding, cytoplasm, nucleus, phospholipid transport, central nervous system development, and cell surface) which were found to be shared among all the traits. -

Mouse Rab14 Conditional Knockout Project (CRISPR/Cas9)
https://www.alphaknockout.com Mouse Rab14 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Rab14 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Rab14 gene (NCBI Reference Sequence: NM_026697 ; Ensembl: ENSMUSG00000026878 ) is located on Mouse chromosome 2. 8 exons are identified, with the ATG start codon in exon 2 and the TAG stop codon in exon 8 (Transcript: ENSMUST00000028238). Exon 3~4 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Rab14 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-198N5 as template. Cas9, gRNA and targeting vector will be co-injected into fertilized eggs for cKO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Exon 3 starts from about 8.22% of the coding region. The knockout of Exon 3~4 will result in frameshift of the gene. The size of intron 2 for 5'-loxP site insertion: 1055 bp, and the size of intron 4 for 3'-loxP site insertion: 3159 bp. The size of effective cKO region: ~2166 bp. The cKO region does not have any other known gene.

Downloaded, Each with Over 20 Samples for AD-Specific Pathways, Biological Processes, and Driver Each Specific Brain Region in Each Condition
Xiang et al. BMC Medical Genomics 2018, 11(Suppl 6):115 https://doi.org/10.1186/s12920-018-0431-1 RESEARCH Open Access Condition-specific gene co-expression network mining identifies key pathways and regulators in the brain tissue of Alzheimer’s disease patients Shunian Xiang1,2, Zhi Huang4, Wang Tianfu1, Zhi Han3, Christina Y. Yu3,5, Dong Ni1*, Kun Huang3* and Jie Zhang2* From 29th International Conference on Genome Informatics Yunnan, China. 3-5 December 2018 Abstract Background: Gene co-expression network (GCN) mining is a systematic approach to efficiently identify novel disease pathways, predict novel gene functions and search for potential disease biomarkers. However, few studies have systematically identified GCNs in multiple brain transcriptomic data of Alzheimer’s disease (AD) patients and looked for their specific functions. Methods: In this study, we first mined GCN modules from AD and normal brain samples in multiple datasets respectively; then identified gene modules that are specific to AD or normal samples; lastly, condition-specific modules with similar functional enrichments were merged and enriched differentially expressed upstream transcription factors were further examined for the AD/normal-specific modules. Results: We obtained 30 AD-specific modules which showed gain of correlation in AD samples and 31 normal- specific modules with loss of correlation in AD samples compared to normal ones, using the network mining tool lmQCM. Functional and pathway enrichment analysis not only confirmed known gene functional categories related to AD, but also identified novel regulatory factors and pathways. Remarkably, pathway analysis suggested that a variety of viral, bacteria, and parasitic infection pathways are activated in AD samples.
