Mouse Brcc3 Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Brcc3 Knockout Project (CRISPR/Cas9) Objective: To create a Brcc3 knockout Mouse model (C57BL/6N) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Brcc3 gene (NCBI Reference Sequence: NM_001166457 ; Ensembl: ENSMUSG00000031201 ) is located on Mouse chromosome X. 11 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 10 (Transcript: ENSMUST00000033544). Exon 5~7 will be selected as target site. Cas9 and gRNA will be co-injected into fertilized eggs for KO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Exon 5 starts from about 36.2% of the coding region. Exon 5~7 covers 26.69% of the coding region. The size of effective KO region: ~2527 bp. The KO region does not have any other known gene.

No significant tandem repeat is found in the dot plot matrix. So this region is suitable for PCR screening or sequencing analysis. Overview of the Dot Plot (down) Window size: 15 bp Forward Reverse Complement Sequence 12 Note: The 2000 bp section downstream of Exon 7 is aligned with itself to determine if there are tandem repeats. Tandem repeats are found in the dot plot matrix. The gRNA site is selected outside of these tandem repeats.

No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated.

Paired-End diTag (PET) analysis possesses a unique capability to accurately and efficiently characterize the two ends of DNA fragments, which may have either normal or unusual compositions. This unique nature of PET analysis makes it an ideal tool for uncovering unconventional features residing in the human genome. Using the PET approach for comprehensive transcriptome analysis, we were able to identify fusion transcripts derived from genome rearrangements and actively expressed retrotransposed pseudogenes, which would be difficult to capture by other means. Here, we demonstrate this unique capability through the analysis of 865,000 individual transcripts in two types of cancer cells.

  • The Impact of the Ubiquitin System in the Pathogenesis of Squamous Cell Carcinomas
    cancers Review The Impact of the Ubiquitin System in the Pathogenesis of Squamous Cell Carcinomas Veronica Gatti 1, Francesca Bernassola 2, Claudio Talora 3, Gerry Melino 2 and Angelo Peschiaroli 1,* 1 National Research Council of Italy, Institute of Translational Pharmacology, 00133 Rome, Italy; [email protected] 2 Department of Experimental Medicine, TOR, University of Rome Tor Vergata, 00133 Rome, Italy; [email protected] (F.B.); [email protected] (G.M.) 3 Department of Molecular Medicine, Sapienza University of Rome, 00185 Rome, Italy; [email protected] * Correspondence: [email protected] Received: 20 May 2020; Accepted: 13 June 2020; Published: 16 June 2020 Abstract: The ubiquitin system is a dynamic regulatory pathway controlling the activity, subcellular localization and stability of a myriad of cellular proteins, which in turn affects cellular homeostasis through the regulation of a variety of signaling cascades. Aberrant activity of key components of the ubiquitin system has been functionally linked with numerous human diseases including the initiation and progression of human tumors. In this review, we will contextualize the importance of the two main components of the ubiquitin system, the E3 ubiquitin ligases (E3s) and deubiquitinating enzymes (DUBs), in the etiology of squamous cell carcinomas (SCCs). We will discuss the signaling pathways regulated by these enzymes, emphasizing the genetic and molecular determinants underlying their deregulation in SCCs. Keywords: squamous cell carcinoma; E3 ubiquitin ligase; deubiquitinating enzymes; oncogenes; tumor suppressor 1. Introduction 1.1. Molecular Landscape of SCCs Squamous cell carcinomas (SCCs) are highly common and malignant solid cancers that arise from stratified and pseudo-stratified epithelia of the skin, and the aerodigestive and genitourinary tracts.

This article is published with open access Abstract BRCA1/BRCA2-containing complex 3 (BRCC3) is a Lysine 63-specific deubiquitinating enzyme (DUB) involved in inflammasome activity, interferon signaling, and DNA damage repair. Recurrent mutations in BRCC3 have been reported in myelodysplastic syndromes (MDS) but not in de novo AML. In one of our recent studies, we found BRCC3 mutations selectively in 9/191 (4.7%) cases with t(8;21)(q22;q22.1) AML but not in 160 cases of inv(16)(p13.1q22) AML. Clinically, AML patients with BRCC3 mutations had an excellent outcome with an event-free survival of 100%. Inactivation of BRCC3 1234567890();,: 1234567890();,: by CRISPR/Cas9 resulted in improved proliferation in t(8;21)(q22;q22.1) positive AML cell lines and together with expression of AML1-ETO induced unlimited self-renewal in mouse hematopoietic progenitor cells in vitro. Mutations in BRCC3 abrogated its deubiquitinating activity on IFNAR1 resulting in an impaired interferon response and led to diminished inflammasome activity.

Peters Veterans Affairs Medical Center, New York, New York ABSTRACT The Connectivity Map database contains microarray signatures of gene expression derived from approximately 6000 experiments that examined the effects of approximately 1300 single drugs on several human cancer cell lines. We used these data to prioritize pairs of drugs expected to reverse the changes in gene expression observed in the kidneys of a mouse model of HIV-associated nephropathy (Tg26 mice). We predicted that the combination of an angiotensin-converting enzyme (ACE) inhibitor and a histone deacetylase inhibitor would maximally reverse the disease-associated expression of genes in the kidneys of these mice. Testing the combination of these inhibitors in Tg26 mice revealed an additive renoprotective effect, as suggested by reduction of proteinuria, improvement of renal function, and attenuation of kidney injury. Furthermore, we observed the predicted treatment-associated changes in the expression of selected genes and pathway components. In summary, these data suggest that the combination of an ACE inhibitor and a histone deacetylase inhibitor could have therapeutic potential for various kidney diseases.
