Cancer-specific association between Tau (MAPT) and cellular pathways, clinical outcome, and drug response

ABSTRACT: Tau (MAPT) is a microtubule-associated protein causing frequent neurodegenerative diseases or inherited frontotemporal lobar degenerations. Emerging evidence for non-canonical functions of Tau in DNA protection and P53 regulation suggests its involvement in cancer. Indeed, Tau expression correlates with cancer-specific survival or response to microtubule therapeutics. These data may imply common molecular pathways involved in the pathogenesis of neurodegenerative disorders and cancer. To bring new evidence that Tau represents a key protein in cancer, we present an in silico pan-cancer analysis of MAPT transcriptomic profile in over 11000 clinical samples and over 1300 pre-clinical samples provided by the TCGA and the DEPMAP datasets respectively. We completed this analysis by exploring a possible interplay of MAPT with wild-type or mutated P53. Then, we calculated the impact of MAPT expression on clinical outcome and drug response. Overall, the results support a relevant role of the MAPT gene in several cancer types, although the contribution of Tau to cancer appears to very much depend on the cellular context.

Identification of proteins that interact with extracellularly applied fibrillar Tau assemblies

Project description:The microtubule associated protein Tau (MAPT) expressed in neurons is involved in microtubules stabilization, cell morphogenesis and axonal transport. In pathological conditions, Tau assembles into high molecular weight assemblies leading to neuropathological Tau deposits, the hallmark of several neurodegenerative diseases collectively named “tauopathies”, including Alzheimer’s disease. These pathologic Tau assemblies are released by affected neuronal cells and taken up by naïve neighbor cells, propagate from one cell to another and amplify by seeding the aggregation of endogenous Tau. In order to identify plasma membrane proteins exposed extracellularly that interact with extracellularly applied fibrillar Tau assemblies, we exposed pure-neuronal cultures to fibrillar Tau for 10 min, pulled down the associated proteins, and identified them using a proteomic-based approach. Of the six Tau isoforms produced by alternative splicing of the MAPT gene and differing from each other by the presence or absence of one or two inserts in the N-terminal part (0N, 1N or 2N) of the protein and by the presence of either three or four repeated microtubule binding motifs in the protein C-terminal part (3R or 4R), we have expressed and purified 1N3R and 1N4R Tau isoforms and further assembled them into 1N3R and 1N4R Tau fibrils. Using pull-down of whole cell lysates and mass spectrometry, we have identified proteins interacting with extracellularly applied Tau fibrils. We have performed two different experiments with either 1N3R Tau fibrils or 1N4R Tau fibrils (condition 1 and condition 2 respectively). Each condition consists in six experimental replicates of cells exposed 10 min to Tau fibrils and of the non-treated cells used as controls.

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.

The effect of the Autoimmune regulator (Aire) gene on mRNA and lncRNA transcriptional profile of mTEC 3.10 cell line

Project description:In this study, we used the murine (Mus musculus) medullary thymic epithelial cell line (mTEC 3.10 cell line) co-cultured with fresh thymocytes as a functional assay for mTEC-thymocyte adhesion. Then we analyzed the differential transcriptional profile of this cell line, by means of Agilent oligo microarray hybridization, comparing Autoimmune regulator (Aire) wild-type cells vs Crispr-Cas9-induced Aire KO cells. The comparative transcriptional expression signatures allowed us to find those differentially expressed mRNAs or lncRNAs between the samples tested.

Synergistic on auxin and cytokinin 1 positively regulates growth and attenuates soil pathogen resistance

Project description:Plants as non-mobile organisms constantly integrate varying environmental signals to flexibly adapt their growth and development. Local fluctuations in water and nutrient availability, sudden changes in temperature or other abiotic and biotic stresses can trigger changes in the growth of plant organs. Multiple mutually interconnected hormonal signaling cascades act as essential endogenous translators of these exogenous signals in the adaptive responses of plants. Although the molecular backbones of hormone transduction pathways have been identified, the mechanisms underlying their interactions are largely unknown. Here, using genome wide transcriptome profiling we identify an unknown auxin and cytokinin cross-talk component; SYNERGISTIC ON AUXIN AND CYTOKININ1 (SYAC1), whose expression in roots is strictly dependent on both of these hormonal pathways. We show that SYAC1 is a component of secretory pathway, whose enhanced activity interferes with deposition of cell wall components and can fine-tune organ growth and sensitivity to soil pathogens

Human pluripotent stem cell-derived kidney organoids reveal tubular epithelial pathobiology of heterozygous HNF1B-associated dysplastic kidney malformations CL

Project description:Hepatocyte nuclear factor 1B (HNF1B) encodes a transcription factor expressed in developing human kidney epithelia. Heterozygous HNF1B mutations are the commonest monogenic cause of dysplastic kidney malformations (DKMs). To understand their pathobiology, we generated heterozygous HNF1B mutant kidney organoids from CRISPR-Cas9 gene-edited human ESCs and iPSCs reprogrammed from a family with HNF1B-asscociated DKMs. Mutant organoids contained enlarged malformed tubules and displayed deregulated cell turnover. This submission is RNAseq of organoids from MAN13 embryonic stem cells.

Identical transcriptome reprograming by interferon lambda 3 and 4 and its absence in IFNLR1 or IL10R2 deficient cells rules out the IFNL4 non-canonical signaling hypothesis

Project description:Lambda interferons IFNL1-3 mediate antiviral immunity by inducing interferon sensitive genes (ISGs) in epithelial tissues. Contrarily, a variant creating the functional gene IFNL4 is associated with impaired clearance of hepatitis C virus (HCV) despite of higher liver expression of ISGs in untreated HCV patients. We aimed to explore IFNL4 signaling mechanism by comparing expression profiles from human hepatic cell line clones with genetic modifications influencing the ISG signaling pathway (IFNLR1/IL10R2 knockouts, IFNL4/IFNL3 expression stimulation by transfection).
