MiR-27a-3p enhances the cisplatin sensitivity in hepatocellular carcinoma cells through inhibiting PI3K/Akt pathway.

MicroRNAs (miRNAs) play an important role in drug resistance, and it is reported that miR-27a-3p regulated the sensitivity of cisplatin in breast cancer, lung cancer and ovarian cancer. However, the relationship between miR-27a-3p and chemosensitivity of cisplatin in hepatocellular carcinoma (HCC) was unclear, especially the underlying mechanism was unknown. In the present study, we analyzed miR-27a-3p expression levels in 372 tumor tissues and 49 adjacent tissues in HCC samples from TCGA database, and found that the miR-27a-3p was down-regulated in HCC tissues.

GP73 promotes epithelial-mesenchymal transition and invasion partly by activating TGF-β1/Smad2 signaling in hepatocellular carcinoma.

The transforming growth factor-β1 (TGF-β1) signaling pathways contribute to cell metastasis and epithelial-mesenchymal transition (EMT). Golgi protein 73 (GP73), a type II transmembrane protein in the Golgi apparatus, was initially regarded as a potential biomarker for the diagnosis of hepatocellular carcinoma (HCC). Recently, it was reported that GP73 acts as a key oncogene by promoting HCC growth and metastasis.

Silencing of GP73 inhibits invasion and metastasis via suppression of epithelial-mesenchymal transition in hepatocellular carcinoma.

Epithelial-mesenchymal transition (EMT) is associated with invasion and metastasis of cancer cells. Golgi protein 73 (GP73) is a serum biomarker for hepatocellular carcinoma (HCC) and our previous study demonstrated that the expression of GP73 correlated with aggressive behavior and EMT molecules in HCC. However, its role in metastatic mechanism of HCC is not clear.

Assessment and prognostic analysis of EGFR mutations or/and HER2 overexpression in Uygur's Non-small Cell Lung Cancer.

Aim: The epidermal growth factor receptor (EGFR) mutations and human epidermal growth factor receptor HER-2/neu (HER2) have been established roles in the signal transduction pathways leading to cell growth and differentiation. The present study focus on the significance of EGFR mutations combined with HER2 overexpression on survival outcomes in Non-small Cell Lung Cancer patients in Uygur population.

Methods: A total of 111 consecutive Uygurods: A total of 111 consecutive Cell Lung Cancer under went lung Cell Lung biopsy or surgery at the Affiliated Tumor Hospital of Xin Jiang Medical University between March 2009 and January 2013 were included in this retrospective study.
