Mouse Bag2 Conditional Knockout Project (CRISPR/Cas9) http://www.alphaknockout.com/ Mouse Bag2 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Bag2 conditional knockout mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Bag2 gene ( NCBI Reference Sequence: NM_145392 ; Ensembl: ENSMUSG00000042215 ) is located on mouse chromosome 1. 3 exons are identified , with the ATG start codon in exon 1 and the TAG stop codon in exon 3 (Transcript: ENSMUST00000044691). Exon 2~3 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the mouse Bag2 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-23B12 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 2 starts from about 18.1% of the coding region. The knockout of Exon 2~3 will result in frameshift of the gene. The size of intron 1 for 5'-loxP site insertion: 9252 bp. The size of effective cKO region: ~3900 bp. This strategy is designed based on genetic information in existing databases. Due to the complexity of biological processes, all risk of loxP insertion on gene transcription, RNA splicing and protein translation cannot be predicted at existing technological level. The function of Gm37905-201 will be affected by deleting this cKO region.

Tandem repeats are found in the dot plot matrix. It may be difficult to construct this targeting vector. Overview of the GC Content Distribution Window size: 300 bp Sequence 12 Summary: Full Length(9343bp) | A(26.45% 2471) | C(23.22% 2169) | G(24.16% 2257) | T(26.18% 2446) Note: The sequence of homologous arms and cKO region is analyzed to determine the GC content. No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.

E. Carey at the University of Michigan, Ann Arbor, MI. The UM-SCC cell lines were derived from eight patients with SCC of the upper aerodigestive tract (supplemental Table 1). Patient age at tumor diagnosis ranged from 37 to 72 years. The cell lines selected were obtained from patients with stage I-IV tumors, distributed among oral, pharyngeal and laryngeal sites. All the patients had aggressive disease, with early recurrence and death within two years of therapy. Cell lines established from single isolates of a patient specimen are designated by a numeric designation, and where isolates from two time points or anatomical sites were obtained, the designation includes an alphabetical suffix (i.e., "A" or "B"). The cell lines were maintained in Eagle's minimal essential media supplemented with 10% fetal bovine serum and penicillin/streptomycin.

This complex recently has been shown to be from the cochaperone small, glutamine-rich, tetratricopeptide important in the TRC pathway, the mislocalized protein degrada- repeat protein 2 (Sgt2) [small glutamine-rich tetratricopeptide tion pathway, and the endoplasmic reticulum-associated degrada- repeat-containing protein (SGTA) in mammals] to the delivery tion pathway. Here we define the architecture of the Bag6 factor Get3 (TRC40 in mammals) (19–22). It is expected that the complex, demonstrating that both TRC35 and Ubl4A have distinct mammalian homologs, along with Bag6, play a similar role (23– C-terminal binding sites on Bag6 defining a minimal Bag6 complex.

  • LOXL1 Confers Antiapoptosis and Promotes Gliomagenesis Through Stabilizing BAG2

This article is published with open access Abstract The lysyl oxidase (LOX) family is closely related to the progression of glioma. To ensure the clinical significance of LOX family in glioma, The Cancer Genome Atlas (TCGA) database was mined and the analysis indicated that higher LOXL1 expression was correlated with more malignant glioma progression. The functions of LOXL1 in promoting glioma cell survival and inhibiting apoptosis were studied by gain- and loss-of-function experiments in cells and animals. LOXL1 was found to exhibit antiapoptotic activity by interacting with multiple antiapoptosis modulators, especially BAG family molecular chaperone regulator 2 (BAG2). LOXL1-D515 interacted with BAG2-K186 through a hydrogen bond, and its lysyl 1234567890();,: 1234567890();,: oxidase activity prevented BAG2 degradation by competing with K186 ubiquitylation. Then, we discovered that LOXL1 expression was specifically upregulated through the VEGFR-Src-CEBPA axis. Clinically, the patients with higher LOXL1 levels in their blood had much more abundant BAG2 protein levels in glioma tissues. Conclusively, LOXL1 functions as an important mediator that increases the antiapoptotic capacity of tumor cells, and approaches targeting LOXL1 represent a potential strategy for treating glioma.

  • CLIP2 As Radiation Biomarker in Papillary Thyroid Carcinoma
    Oncogene (2015) 34, 3917–3925 © 2015 Macmillan Publishers Limited All rights reserved 0950-9232/15 www.nature.com/onc ORIGINAL ARTICLE CLIP2 as radiation biomarker in papillary thyroid carcinoma M Selmansberger1, A Feuchtinger2, L Zurnadzhy3, A Michna1, JC Kaiser4, M Abend5, A Brenner6, T Bogdanova3, A Walch2, K Unger1,7, H Zitzelsberger1,7 and J Hess1,7 A substantial increase in papillary thyroid carcinoma (PTC) among children exposed to the radioiodine fallout has been one of the main consequences of the Chernobyl reactor accident. Recently, the investigation of PTCs from a cohort of young patients exposed to the post-Chernobyl radioiodine fallout at very young age and a matched nonexposed control group revealed a radiation-specific DNA copy number gain on chromosomal band 7q11.23 and the radiation-associated mRNA overexpression of CLIP2. In this study, we investigated the potential role of CLIP2 as a radiation marker to be used for the individual classification of PTCs into CLIP2- positive and -negative cases—a prerequisite for the integration of CLIP2 into epidemiological modelling of the risk of radiation- induced PTC. We were able to validate the radiation-associated CLIP2 overexpression at the protein level by immunohistochemistry (IHC) followed by relative quantification using digital image analysis software (P = 0.0149). Furthermore, we developed a standardized workflow for the determination of CLIP2-positive and -negative cases that combines visual CLIP2 IHC scoring and CLIP2 genomic copy number status. In addition to the discovery cohort (n = 33), two independent validation cohorts of PTCs (n = 115) were investigated. High sensitivity and specificity rates for all three investigated cohorts were obtained, demonstrating robustness of the developed workflow.

Here, ten putative SlBAG genes were identified in tomato. SlBAG2 and SlBAG5b have the same gene structure and conserved domains, along with highly similar identity to their homologs in Arabidopsis thaliana, Oryza sativa, and Triticum aestivum. The qPCR data showed that BAG2 and BAG5b were highly expressed in stems and flowers. Moreover, both genes were differentially expressed under diverse abiotic stimuli, including cold stress, heat stress, salt treatment, and UV irradiation, and treatments with phytohormones, namely, ABA, SA, MeJA, and ETH. Subcellular localization showed that SlBAG2 and SlBAG5b were located in the cell membrane and nucleus.

Strategy summary: The Bag2 gene (NCBI Reference Sequence: NM_145392 ; Ensembl: ENSMUSG00000042215 ) is located on Mouse chromosome 1. 3 exons are identified, with the ATG start codon in exon 1 and the TAG stop codon in exon 3 (Transcript: ENSMUST00000044691). Exon 1~3 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 1 starts from about 0.16% of the coding region. Exon 1~3 covers 100.0% of the coding region. The size of effective KO region: ~12080 bp. The function of mouse Gm37905 will be affected by deleting this KO region..

OPEN ACCESS Abstract Hsp70 proteins are keys to maintaining intra-cellular protein homeostasis. To carry Keywords out this task, they employ a large number of co-chaperones and adapter proteins. Here • Hsp70 proteins we review what is known about the interaction between the chaperones and partners, • Protein chaperones with a strong slant towards structural biology. Hsp70s in general and Hsc70 (HSPA8) in particular, display an amazing array of interfaces with their protein co-factors. We also reviewed the known interactions between Hsp70s and active compounds that may become leads towards Hsp70 modulation for treatment of a variety of diseases. INTRODUCTION misfolded proteins to favor protein (re)folding cycles [6]; (ii) transporting unfolded proteins through membranes to enable Hsp70 chaperones are highly conserved in all kingdoms; delivery of cargo to organelles [7]; (iii) recruiting proteins to in animals, they are an important member of the collection of the proteasome for turnover [8] and (iv) bringing proteins to protein chaperones including Hsp60, Hsp70, Hsp90 and small Hsps [1].

  • Investigations Into the Cellular Interactome of the PB2 Protein Expressed by Seasonal and Highly Pathogenic Avian Influenza Viruses
    Investigations into the cellular interactome of the PB2 protein expressed by seasonal and highly pathogenic avian influenza viruses D i s s e r t a t i o n zur Erlangung des akademischen Grades d o c t o r r e r u m n a t u r a l i u m (Dr. rer. nat.) im Fach Biologie eingereicht an der Lebenswissenschaftlichen Fakultät der Humboldt-Universität zu Berlin von Ulrike Arnold Präsidentin der Humboldt-Universität zu Berlin Prof. Dr.-Ing. Dr. Sabine Kunst Dekan der Lebenswissenschaftlichen Fakultät Prof. Dr. Bernhard Grimm Gutachter: 1. Prof. Andreas Herrmann 2. PD Thorsten Wolff 3. Dr. Benedikt Beckmann Tag der mündlichen Prüfung: 10.07.2018 Abstract Influenza virus replication relies on the functionality of its trimeric RNA dependent RNA polymerase complex under the conditions provided by the infected cell. PB2 is an essential component of this complex and is known to be a key factor for influenza virus host range. Given its importance, the interplay of PB2 with the cellular host proteome was investigated in several studies and various interaction partners such as protein phosphatase 6 (PP6) have been reported. However, these studies were mostly performed with laboratory/mouse- adapted strains or in the context of transiently transfected cells. Here, a combined affinity-purification/mass spectrometric approach was performed to identify novel interaction partners of PB2 of seasonal and highly pathogenic viral strains in infected human alveolar epithelial cells (A549). The subsequent analysis of selected cellular interaction partners aimed to determine the influence of these proteins on the replication cycle of these non-laboratory adapted viral strains.
