Time-resolved analysis of proteolytic products of ANXA1 by recombinant HTRA1

ABSTRACT: A proteolytic cleavage experiment was performed with the recombinant unfolded protein Annexin A1 (ANXA1) and recombinant HTRA1_∆mac protease, to identify cleavage sites in ANXA1. In this experiment, unfolded and denatured ANXA1 was used to compare the cleavage sites that are cleaved efficiently and are surface exposed or not.

Time-resolved analysis of proteolytic cleavage sites in Malate dehydrogenase by Trypsin.

Project description:A proteolytic cleavage experiment was performed with the protein Malate dehydrogenase (MDH) and Trypsin protease, to identify early cleavage sites in MDH. Various concentrations of Trypsin (5,000, 10,000 and 100,000 x diluted) were tested and early timepoints taken to detect only few cleavage sites in order to identify the very first events of MDH proteolysis

Investigation of xylan degradation in Thermococcus sp. 2319x1E

Project description:Thermococcus sp. 2319x1E is able to grow on different mono- or polysaccharides as carbon source, including xylan. To investigate xylan degradation in Thermococcus sp. 2319x1E, cells were grown on 4 different carbon sources for 12 h (mid-exponential phase) and harvested by centrifugation. Using a label-free quantification approach the whole proteomes were analyzed. In another experiment a glycosidase specific activity-based probe (JJB384) was used to isolate specific Thermococcus glycosidases activated during growth on xylan or xylose.

Degradome sequencing from S. castellii

Project description:The RNA-induced silencing complex, comprising Argonaute and guide RNA, mediates RNA interference. Here we report the 3.2 M-CM-^E crystal structure of Kluyveromyces Argonaute (KpAGO) fortuitously complexed with guide RNA originating from small-RNA duplexes autonomously loaded by recombinant KpAGO. Despite their diverse sequences, guide-RNA nucleotides 1-8 are positioned similarly, with sequence-independent contacts to bases, phosphates and 2'-hydroxyl groups pre-organizing the backbone of nucleotides 2-8 in a near-A-form conformation. Compared with prokaryotic Argonautes, KpAGO has numerous surface-exposed insertion segments, with a cluster of conserved insertions repositioning the N domain to enable full propagation of guide-target pairing. Compared with Argonautes in inactive conformations, KpAGO has a hydrogen-bond network that stabilizes an expanded and repositioned loop, which inserts an invariant glutamate into the catalytic pocket. Mutation results and analogies to Ribonuclease H indicate that insertion of this glutamate finger completes a universally conserved catalytic tetrad, thereby activating Argonaute for cleavage. High-throughput sequencing of cellular RNAs containing both a 5'-monophosphate group and a poly(A) tail. To identify Argonaute-dependent cleavage tags, sequencing libraries were prepared from M-NM-^Txrn1 and M-NM-^Txrn1 M-NM-^Tago1 strains.

Transcription profiling by array of human breast cancer cell line BT-474 with annexin A1 over-expression or silenced with siRNA to demonstrate design of multi-condition experiments

Project description:Multiple-condition experiment was desinged to be any number of conditions in an experiment without replicate observations for microarray and used to identify genes differentially expressed between different pairs of conditions (treatments).<br> In this study we used breast cancer stable cell lines for overexpressing and silencing annexin A1 (ANXA1), which belongs to a family of -dependent phospholipid binding proteins and are preferentially located on the cytosolic face of the plasma membrane. Cell lines overexpressing ANXA1 (MDA_MB-453/cDNA) were generated by introducing retroviral vectors containing ANXA1 cDNA (pBabe/ANXA1 cDNA) into breast cancer cell line MDA-MB-453 (a low expressor of ANXA1). Breast cancer cell line BT-474, a high expressor of ANXA1, was infected with ANXA1 siRNA-plasmid viruses to knockdown ANAXAI expressor (BT-474/siRNA) where nucleotides corresponding to siRNA were synthesized and ligated into the pLNCX retroviral vector [35,36]. We also used a pLNCX/U6 empty vector to infect BT-474 and obtained an empty vector expressor. Therefore, 5 breast cancer cell lines (MDA_MB-453, MDA_MB-453/cDNA, BT-474, BT-474/siRNA, and BT-474/U6) are attributed to two genotypes: MDA_MB-453 and BT-474. MCE was performed for microarray analysis with these 5 breast cancer cell lines, that is, only one sample was drawn from each breast cancer cell line.

miR-196a is able to restore the aggressive phenotype of Annexin A1 CRISPR/Cas9 knock-out pancreatic cancer cells

Project description:Annexin A1 (ANXA1) is a Ca2+-binding protein involved in pancreatic cancer (PC) progression. It is able to mediate cytoskeletal organization maintaining a malignant phenotype. ANXA1 Knock-Out (KO) MIA PaCa-2 cells partially lost their migratory and invasive capabilities and also the metastatization process is affected in vivo. Here, we investigated the microRNA (miRNA) profile in ANXA1 KO cells. The analysis of the modification in miRNA expression remarked the significant involvement of ANXA1 in PC progression. In this study, we focused on miR-196a which is a well known oncogenic factor in several tumour models and it appeared down-modulated in absence of ANXA1. Furthermore, both ANXA1 and miR-196a are able to trigger the mechanisms of the epithelial to mesenchymal transition (EMT). Our results show that the reintroduction of miR-196a through the mimic sequence restored the early aggressive phenotype of MIA PaCa-2. Then, ANXA1 seems to support the expression of miR-196a and its role. On the other hand, this miRNA is able to mediate some of protein functions in PC progression. This work elucidates the correlation between ANXA1 and specific miRNA sequences, particularly miR-196a, and provides new knowledge about the protein intracellular role.

miRNA expression data from MCF-7 cells, overexpressing ANXA1

Project description:Annexin 1 (ANXA1), an endogenous anti-inflammatory protein which modulates cellular processes such as proliferation, differentiation and apoptosis has been implicated in cancer initiation and progression. ANXA1 was previously shown to be regulated by hsa-miR-196a and promoted cell proliferation and anchorarge-dependent growth and suppressed apoptosis. However, whether ANXA1 itself regulates miRNA expression is unknown. Therefore, in this study, we investigated the regulation of miRNA by ANXA1 in breast cancer cells. Using microarray technology, 12 miRNAs were found to be significantly and consistently downregulated in MCF-7 cells (MCF-V5) overexpressing ANXA1 overexpressing MCF-7 cells (MCF-V5). Hsa-miR-26b* and hsa-miR-562 were chosen for further investigation.The data suggest that miR-26b* and miR-562 may play a role in ANXA1-induced migration and possibly angiogenesis by targeting NFKB and point towards a potential therapeutic target for breast cancer. Breast cancer MCF-7 cells (MCF-V5) overexpressing ANXA1 were cultured for RNA extraction and hybridization on Affymetrix miRNA microarrays. These were compared against the control, which were MCF-7 cells (MCF-EV) carrying an empty expression vector. Expression analyses were carried out in triplicates

CBC-ARS2 stimulates 3'-end maturation of multiple RNA families and favors cap-proximal processing

Project description:The nuclear cap-binding complex (CBC) stimulates multiple steps in several RNA maturation pathways, but how it functions in humans is incompletely understood. For small capped RNAs like pre-snRNAs, the CBC recruits PHAX. Here, we identify the CBCAP complex, composed of CBC, Ars2 and PHAX, and show that both CBCAP and CBC-Ars2 complexes can be reconstituted from recombinant proteins. Ars2 stimulates PHAX binding to the CBC as well as snRNAs 3'-end processing, hereby coupling maturation with export. In vivo, CBC and Ars2 bind similar capped non-coding and coding RNAs, and stimulate their 3M-bM-^@M-^Y-end processing. Strongest effects are displayed for cap-proximal polyadenylation sites, thereby favoring premature transcription termination. Ars2 functions in part through the mRNA 3M-bM-^@M-^Y-end cleavage factor CLP1, which binds RNA Polymerase II through PCF11. Ars2 is thus a major CBC effector that stimulates functional and cryptic 3'-end processing sites. In total 12 samples; 4 control IP, 2 Flag- Ars2 IP and 2 Flag-CBP20 IP; 2 control FFL siRNA and 2 siRNA Ars2
