The expansion of cancer-induced myeloid cells is thought to be one of the main obstacles to successful immunotherapy. Nevertheless, in murine tumors undergoing immune-mediated destruction by adoptively transferred T cells, we have recently shown that such cells maintain their immunosuppressive properties. Therefore, adoptive T-cell therapy can, under certain conditions, overcome myeloid cell im...

Myeloid-derived suppressor cells are a heterogeneous group of pathologically activated immature cells that play a major role in the negative regulation of the immune response in cancer, autoimmunity, many chronic infections, and inflammatory conditions, as well as in the regulation of tumor angiogenesis, tumor cell invasion, and metastases. Accumulation of myeloid-derived suppressor cells is go...

background and objective: p53 is a suppressive gene that plays a key role in dna repair and apoptosis. the purpose of this study was to investigate the effect of p53 protein over-expression and some clinicopathological factors on the esophageal squamous cell carcinoma (scc) response to neoadjuvant chemoradiotherapy. patients and methods: in this retrospective cohort study, 44 patients with loca...

introdouction: squamous cell carcinoma is the most common oral cancer and the prognosis because of a late diagnosis remains poor despite numerous treatments. therefore, we conducted a cross-sectional study to investigate the relationships between survival rate(sr) of oral squamous cell carcinoma (oscc) and clinical,demographic, pathological, and molecular factors in yazd city during 1998– 2008....

conclusions despite the fact that abnormalities in p53 and p27kip1 may be involved in the development of oscc, their clinical significance in the studied population seems limited. further investigation on the combined p53/p27kip1 expression may be helpful in predicting the biologic behavior of this tumor. results p53 and p27kip1 expression were found in 28.57% (8 positive versus 20 negative) an...
