China Received September 28, 2019; Accepted May 7, 2020 DOI: 10.3892/ol.2020.11752 Abstract. Hepatocellular carcinoma (HCC) is a heterogeneous cyclin B1 (CCNB1), cell-division cycle protein 20 (CDC20), malignancy, which is a major cause of cancer morbidity and cyclin-dependent kinase 1, BUB1 mitotic checkpoint serine/ mortality worldwide. Thus, the aim of the present study was threonine kinase β (BUB1B), cyclin A2, nucleolar and spindle to identify the hub genes and underlying pathways of HCC associated protein 1, ubiquitin‑conjugating enzyme E2 C via bioinformatics analyses. The present study screened three (UBE2C) and ZW10 interactor. Furthermore, upregulated datasets, including GSE112790, GSE84402 and GSE74656 CCNB1, CDC20, BUB1B and UBE2C expression levels from the Gene Expression Omnibus (GEO) database, and indicated worse disease-free and overall survival. Moreover, downloaded the RNA-sequencing of HCC from The Cancer a meta-analysis of tumor and healthy tissues in the Oncomine Genome Atlas (TCGA) database. -

Read Full License Page 1/23 Abstract Background: Breast cancer (BRCA) remains one of the most common forms of cancer and is the most prominent driver of cancer-related death among women. The mechanistic basis for BRCA, however, remains incompletely understood. In particular, the relationships between driver mutations and signaling pathways in BRCA are poorly characterized, making it dicult to identify reliable clinical biomarkers that can be employed in diagnostic, therapeutic, or prognostic contexts. Methods: First, we downloaded publically available BRCA datasets (GSE45827, GSE42568, and GSE61304) from the Gene Expression Omnibus (GEO) database. We then compared gene expression proles between tumor and control tissues in these datasets using Venn diagrams and the GEO2R analytical tool. We further explore the functional relevance of BRCA-associated differentially expressed genes (DEGs) via functional and pathway enrichment analyses using the DAVID tool, and we then constructed a protein-protein interaction network incorporating DEGs of interest using the Search Tool for the Retrieval of Interacting Genes (STRING) database. -

Protein Interaction Network of Alternatively Spliced Isoforms from Brain Links Genetic Risk Factors for Autism

Iakoucheva1 Increased risk for autism spectrum disorders (ASD) is attributed to hundreds of genetic loci. The convergence of ASD variants have been investigated using various approaches, including protein interactions extracted from the published literature. However, these datasets are frequently incomplete, carry biases and are limited to interactions of a single splicing isoform, which may not be expressed in the disease-relevant tissue. Here we introduce a new interactome mapping approach by experimentally identifying interactions between brain-expressed alternatively spliced variants of ASD risk factors. The Autism Spliceform Interaction Network reveals that almost half of the detected interactions and about 30% of the newly identified interacting partners represent contribution from splicing variants, emphasizing the importance of isoform networks. Isoform interactions greatly contribute to establishing direct physical connections between proteins from the de novo autism CNVs. Our findings demonstrate the critical role of spliceform networks for translating genetic knowledge into a better understanding of human diseases. -

Mouse Casp8ap2 Conditional Knockout Project (CRISPR/Cas9)
https://www.alphaknockout.com Mouse Casp8ap2 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Casp8ap2 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Casp8ap2 gene (NCBI Reference Sequence: NM_011997 ; Ensembl: ENSMUSG00000028282 ) is located on Mouse chromosome 4. 11 exons are identified, with the ATG start codon in exon 2 and the TAG stop codon in exon 10 (Transcript: ENSMUST00000029950). Exon 4 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Casp8ap2 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-75H14 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: Mice homozygous for disruption of this gene die before implantation. Exon 4 starts from about 2.12% of the coding region. The knockout of Exon 4 will result in frameshift of the gene. The size of intron 3 for 5'-loxP site insertion: 819 bp, and the size of intron 4 for 3'-loxP site insertion: 639 bp. The size of effective cKO region: ~601 bp. The cKO region does not have any other known gene.

Par6c Is at the Mother Centriole and Controls Centrosomal Protein
860 Research Article Par6c is at the mother centriole and controls centrosomal protein composition through a Par6a-dependent pathway Vale´rian Dormoy, Kati Tormanen and Christine Su¨ tterlin* Department of Developmental and Cell Biology, University of California, Irvine, Irvine, CA 92697-2300, USA *Author for correspondence ([email protected]) Accepted 3 December 2012 Journal of Cell Science 126, 860–870 ß 2013. Published by The Company of Biologists Ltd doi: 10.1242/jcs.121186 Summary The centrosome contains two centrioles that differ in age, protein composition and function. This non-membrane bound organelle is known to regulate microtubule organization in dividing cells and ciliogenesis in quiescent cells. These specific roles depend on protein appendages at the older, or mother, centriole. In this study, we identified the polarity protein partitioning defective 6 homolog gamma (Par6c) as a novel component of the mother centriole. This specific localization required the Par6c C-terminus, but was independent of intact microtubules, the dynein/dynactin complex and the components of the PAR polarity complex. Par6c depletion resulted in altered centrosomal protein composition, with the loss of a large number of proteins, including Par6a and p150Glued, from the centrosome. As a consequence, there were defects in ciliogenesis, microtubule organization and centrosome reorientation during migration. Par6c interacted with Par3 and aPKC, but these proteins were not required for the regulation of centrosomal protein composition. Par6c also associated with Par6a, which controls protein recruitment to the centrosome through p150Glued. Our study is the first to identify Par6c as a component of the mother centriole and to report a role of a mother centriole protein in the regulation of centrosomal protein composition. -
