Constitutively nuclear FOXO3a localization predicts poor survival and promotes Akt phosphorylation in breast cancer.

Background: The PI3K-Akt signal pathway plays a key role in tumorigenesis and the development of drug-resistance. Cytotoxic chemotherapy resistance is linked to limited therapeutic options and poor prognosis.

Methodology/principal Findings: Examination of FOXO3a and phosphorylated-Akt (P-Akt) expression in breast cancer tissue microarrays showed nuclear FOXO3a was associated with lymph node positivity (p = 0.

Granulin-epithelin precursor as a therapeutic target for hepatocellular carcinoma.

Unlabelled: Primary liver cancer, hepatocellular carcinoma (HCC), is the fifth most common cancer and the third leading cancer killer in the world. There is no effective therapeutic option for most HCC patients. A new therapeutic strategy is essential.

GEP associates with wild-type p53 in hepatocellular carcinoma.

Granulin-epithelin precursor (GEP) is a novel growth factor whose up-regulation we previously reported in 72% of hepatocellular carcinoma (HCC). GEP expression has been reported to be associated with p53 protein accumulation in a breast cancer study, though the p53 mutation status was not revealed. We aim to investigate whether p53 protein and mutation status correlates with GEP expression in HCC.

Granulin-epithelin precursor overexpression promotes growth and invasion of hepatocellular carcinoma.

Purpose: Granulin-epithelin precursor (GEP) is a novel growth factor. Our earlier cDNA microarray study indicated that GEP was overexpressed in hepatocellular carcinoma (HCC). The aim of this study was to investigate the clinical significance of GEP expression and its potential as a therapeutic target in HCC.

Identify metastasis-associated genes in hepatocellular carcinoma through clonality delineation for multinodular tumor.

Disease recurrence and metastasis are frequently observed in many successfullytreated localized cancers, including hepatocellular carcinoma in which intrahepatic and extrahepatic recurrence (metastasis) are frequently observed after curative resection. The present study aimed at identifying metastasis-associated genes through delineation of the clonality for multinodular liver cancer. The clonal relationship of 22 tumor foci from six patients was investigated by the genome-wide expression profile via cDNA microarray consisting of 23,000 genes.

Liver as an ideal target for gene therapy: expression of CTLA4Ig by retroviral gene transfer.

Background And Aims: Liver has been a target organ for gene therapy as it plays a central role in metabolism and production of serum proteins. Many metabolic disorders result from a deficiency of liver-derived protein products. In transplantation settings, modulation of the immune responses caused by CTLA4Ig protein has been shown to be an attractive direction.
