Estrogen receptor (ER)-negative breast cancers are a group of tumors with poor prognosis and fewer cancer prevention and treatment strategies compared to ER-positive tumors. The aim of this study was to assess the morphological characteristics and immunohistochemical profile of ER-negative tumors and thus to understand the biological behavior and unique(More)
Hepatocellular carcinoma (HCC) is an aggressive cancer with a poor prognosis. Autophagy and hypoxia have been involved in HCC tumorigenesis. In the present study, we examined the relationship between Beclin-1 expression and hypoxia-inducible factor (HIF)-1α expression in HCC by immunohistochemistry on 65 tumor specimens. Their correlations with(More)
