MUC1 oncoprotein promotes refractoriness to chemotherapy in thyroid cancer cells.

2007

Abstract Overexpression of MUC1 oncoprotein is frequently observed in cancer and contributes to confer resistance to genotoxic agents. Papillary, follicular, and anaplastic thyroid carcinomas are the three forms of thyroid epithelial cancer. Anaplastic tumors are less differentiated and extremely aggressive, characterized by a poor prognosis. Little is known about the role of MUC1 in thyroid cancer. We recently showed that autocrine production of interleukin (IL)-4 and IL-10 controls thyroid cancer cell survival, growth, and resistance to chemotherapy through activation of Janus-activated kinase/signal transducers and activators of transcription (JAK/STAT) and phosphatidylinositide 3′-OH ki…

Autocrine production of interleukin-4 and interleukin-10 is required for survival and growth of thyroid cancer cells.

2006

AbstractAlthough CD95 and its ligand are expressed in thyroid cancer, the tumor cell mass does not seem to be affected by such expression. We have recently shown that thyroid carcinomas produce interleukin (IL)-4 and IL-10, which promote resistance to chemotherapy through the up-regulation of Bcl-xL. Here, we show that freshly purified thyroid cancer cells were completely refractory to CD95-induced apoptosis despite the consistent expression of Fas-associated death domain and caspase-8. The analysis of potential molecules able to prevent caspase-8 activation in thyroid cancer cells revealed a remarkable up-regulation of cellular FLIPL (cFLIPL) and PED/PEA-15, two antiapoptotic proteins whos…

A non-redundant role for OX40 in the competitive fitness of Treg in response to IL-2.

2010

OX40 stimulation is known to enhance activation of effector T cells and to inhibit induction and suppressive function of Treg. Here we uncovered a novel role of OX40 in sustaining Treg competitive fitness in vivo, during repopulation of lymphopenic hosts and reconstitution of BM chimeras. Defective expansion of OX40-null Treg diminished their ability to suppress inflammation in a model of lymphopenia-driven colitis. OX40-mediated promotion of Treg fitness spanned beyond lymphopenic environments, as endogenous Treg in OX40-null mice showed decreased accumulation during thymic development, enhanced susceptibility to antibody-mediated depletion and defective turnover following thymectomy. In v…

Differential expression of suppressors of cytokine signaling-1, -2, and -3 in the rat hippocampus after seizure: implications for neuromodulation by …

2003

Numerous studies have investigated the expression of various cytokine families in the CNS after brain injury. The gp130 or interleukin (IL)-6-type cytokines have received a great deal of focus, and it is clear that they exhibit an acute and robust upregulation in various brain injury models. We are interested to determine, however, whether endogenously expressed cytokines in the CNS act in a direct neuromodulatory manner. In an accompanying study, we examined the expression of five gp130 cytokines and their receptors in the lithium-pilocarpine model of status epilepticus. We follow up that study here by trying to determine if gp130 signal transduction occurs in hippocampal principal neurons…

Functional polymorphisms in SOCS1 and PTPN22 genes correlate with the response to imatinib treatment in newly diagnosed chronic-phase chronic myeloid…

2011

a b s t r a c t The function of the natural modulators of BCR-ABL-induced signaling pathways could influence the results to imatinib treatment. We assessed the association between single nucleotide polymorphisms (SNPs) on genes of the phosphatase family and the suppressors of cytokine signaling and the response to imatinib in 105 patients newly diagnosed with chronic-phase CML. SNPs in SOCS1 (rs243327) and PTPN22 (rs2476601) genes correlated with the risk of primary resistance to imatinib. A high-risk Sokal score, the T allele in PTPN22 SNP, and each copy of the C allele in SOCS1 SNP were adverse prognostic factors for failure-free survival (FFS). Based on such parameters, three risk groups…

Suppressor of cytokine signaling 3 sensitizes anaplastic thyroid cancer to standard chemotherapy

2009

We previously showed that cancer cells from papillary, follicular, and anaplastic thyroid carcinomas produce interleukin-4 and interleukin-10, which counteract the cytotoxic activity of conventional chemotherapy through the up-regulation of antiapoptotic molecules. Here, we identify Janus kinase/signal transducers and activators of transcription (STAT) and phosphatidyl inositol 3-kinase (PI3K)/AKT as the down-stream pathways through which these cytokines confer resistance to cell death in thyroid cancer. We found that the absence of suppressors of cytokine signaling (SOCS) molecules allows the propagation of the survival signaling. Exogenous expression of SOCS1, SOCS3, and SOCS5 in the high…
