Article Title: Upregulation of nucleoprotein AHNAK is associated with poor outcome of pancreatic ductal adenocarcinoma prognosis via mediating epithelial-mesenchymal transition

doi: 10.7150/jca.31291

Figure Lengend Snippet: AHNAK mediates the EMT to promote PDAC cell proliferation and migration via TP53 signaling pathway. A: GSEA was carried out in the paired PDAC samples in GEO database. It showed that most biomarkers were involved in the EMT phenotype. B: Western blotting analysis showed that AHNAK suppression caused an increase in E-cadherin but a decrease in N-cadherin. C and D: The qPCR results showed the alteration of gene expression in EMT phenotype after knockdown of AHNAK.

Article Snippet: Recombinant p53 protein was purchased from Origene (Catalog: TP710022) and Cell culture experiments were used to verify the predictions.

Article Title: Upregulation of nucleoprotein AHNAK is associated with poor outcome of pancreatic ductal adenocarcinoma prognosis via mediating epithelial-mesenchymal transition

doi: 10.7150/jca.31291

Figure Lengend Snippet: AHNAK mediates the EMT via TP53 signaling pathway. A: Western blot analysis showed that after knockdown of AHNAK, only expression of TP53 was altered, while other markers, including AKT and ERK. The phosphorylated level of TP53, AKT and ERK also showed no alterations. B: qRT-PCR showed the alteration of markers in TP53 signaling pathway. C: GSEA suggested an enrichment of TP53 signaling pathway in PDAC by analyzing the GEO database. D: Western blot showed after the recombinant TP53 protein was added into the AHNAK deficiency cell lines, E-cad, the epithelial markers of EMT phenotype was restored. E and F: CCK-8 and Transwell assays showed that recombinant TP53 could restore cellular proliferation and migration.

( A ) Inhibition of galectin-7 mRNA levels by CAPE in MDA-MB-453 cells transfected with the expression vector encoding p53 R175H or with the (empty) pCDNA3.1 control vector (CTRL). GAPDH was used as loading control. ( B ) Effect of CAPE on NF-κB reporter activity in MDA-MB-453 cells transfected with the expression vector encoding p53 R175H or with the (empty) pCDNA3.1 control vector (CTRL). Transfection efficiency was normalized by co-transfection with a β-galactosidase reporter vector.

Article Title: Identifying the substrate proteins of U-box E3s E4B and CHIP by orthogonal ubiquitin transfer

doi: 10.1126/sciadv.1701393

Figure Lengend Snippet: ( A ) fE4B-KB2 and fE4B-KB12 could assemble an OUT cascade with xUba1 and xUbcH5b to mediate xUB transfer to p53. The efficiency of p53 ubiquitination by xUB and the OUT cascade was similar to p53 ubiquitination with wt UB and the wt Uba1-UbcH5b-fE4B cascade. In contrast, wt E4B could not pair with xUba1-xUbcH5b to transfer xUB to p53, suggesting the orthogonality between the OUT cascade and native E3s. Mutant fE4B KB2 or KB12 could not pair with wt Uba1–wt UbcH5b to transfer wt UB to p53. ( B ) Similar to E4B OUT cascade, CHIP-KB2 and CHIP-KB12 could relay with xUba1-xUbcH5b to transfer xUB to p53. The efficiency of xUB modification of p53 by the CHIP OUT cascades was similar to that of p53 modification by wt UB going through the wt Uba1-UbcH5b-CHIP cascade. xUB could not be transferred to p53 with the crossover cascade of xUba1-xUbcH5b–wt CHIP. wt UB could not be transferred to p53 with the crossover cascade of wt Uba1–wt UbcH5b–mutant CHIP (KB2 or KB12).
