Annexin-1 downregulation in thyroid cancer correlates to the degree of tumour differentiation

2006

We investigated the expression of annexin-1 (ANXA1) in thyroid carcinoma cell lines and in thyroid cancers with a different degree of differentiation. The highest level of ANXA1 expression examined by Western blotting was detected in the papillary carcinoma cells (NPA) and in the follicular cells (WRO). On the other hand, the most undifferentiated thyroid carcinoma cells (ARO and FRO) presented the lowest level of ANXA1 expression. In surgical tissue specimens from 32 patients with thyroid cancers, we found high immunoreactivity for ANXA1 in papillary (PTC) and follicular (FTC) thyroid cancers while in undifferentiated thyroid cancers (UTC) the expression of the protein was barely detectabl…

NF-κB protects Behçet's disease T cells against CD95-induced apoptosis up-regulating antiapoptotic proteins

2005

Objective To determine whether prolongation of the inflammatory reaction in patients with Behcet's disease (BD) is related to apoptosis resistance and is associated with the up-regulation of antiapoptotic factors. Methods The percentage of cell death was evaluated by flow cytometry in peripheral blood mononuclear cells from 35 patients with BD and 30 healthy volunteers. The expression levels of antiapoptotic factors and NF-κB regulatory proteins were measured using Western blotting and immunohistochemical analyses. To down-regulate NF-κB nuclear translocation, BD T lymphocytes were exposed in vitro to thalidomide and subjected to transfection with NF-κB small interfering RNA. Results Althou…
