BMC Cancer 2013, 13:517 http://www.Amprenavir biomedcentral/1471-2407/13/RESEARCH ARTICLEOpen AccessCD26 Expression on T-Anaplastic Massive Cell Lymphoma (ALCL) Line Karpas 299 is linked with improved expression of Versican and MT1-MMP and enhanced adhesionPamela A Havre1, Extended H Dang1, Kei Ohnuma2, Satoshi Iwata2, Chikao Morimoto2 and Nam H Dang1,3*AbstractBackground: CD26/dipeptidyl peptidase IV (DPPIV) can be a multifunctional membrane protein using a key function in T-cell biology and also serves as a marker of aggressive cancers, which includes T-cell malignancies.Tisotumab vedotin Procedures: Versican expression was measured by real-time RT-PCR and Western blots.PMID:24513027 Gene silencing of versican in parental Karpas 299 cells was performed employing transduction-ready viral particles. The effect of versican depletion on surface expression of MT1-MMP was monitored by flow cytometry and surface biotinylation. CD44 secretion/ cleavage and ERK (1/2) activation was followed by Western blotting. Collagenase I activity was measured by a live cell assay and in vesicles utilizing a liquid-phase assay. Adhesion to collagen I was quantified by an MTS assay. Results: Versic.
