Metformin potentiates the anticancer activities of gemcitabine and cisplatin against cholangiocarcinoma cells in vitro and in vivo.

Metformin, an oral biguanide drug used to treat type 2 diabetes, has displayed anticancer activities in several types of cancer cells. The combination of gemcitabine and cisplatin is the standard chemotherapy regimen for cholangiocarcinoma, but its benefit is limited. The present study aimed to investigate whether metformin could enhance the activities of gemcitabine and cisplatin against cholangiocarcinoma, and the underlying mechanisms.

Aldosterone and TGF-β₁ synergistically increase PAI-1 expression in hepatic stellate cells of rats.

Aberrant expression of microRNAs in serum may identify individuals with pancreatic cancer.

Pancreatic cancer (PC) has the poorest survival rate among all types of human cancer due to the lack of sensitive and non-invasive diagnostic screen methods for PC screening. Our aim was to identify novel serum microRNA (miRNA) biomarkers for the early detection of PC. We used microarray to screen differential expression of miRNAs in two pooled serum samples (6 PC patients and 6 healthy controls).

Monocarboxylate transporter 4 predicts poor prognosis in hepatocellular carcinoma and is associated with cell proliferation and migration.

Purpose: Monocarboxylate transporter 4 (MCT4) is a critical component in the glycolytic metabolism of cancer cells, and is also important for malignant behavior. We investigated the expression profile of MCT4, its prognostic value in hepatocellular carcinoma (HCC) patients, its role in HCC cell proliferation and metastasis, and associated initial molecular mechanism.

Methods: MCT4 expression was examined through immunohistochemical staining of pathological specimens from 318 HCC patients who had undergone hepatectomy.

Association of the expression of unc-51-Like kinase 1 with lymph node metastasis and survival in patients with esophageal squamous cell carcinoma.

Unc-51-Like Kinase 1 (ULK1) is regarded as a central role in autophagy. Although the details of how ULK1 triggers autophagy are obscure, the relationship between ULK1 expression and the diagnosis and prognosis of cancer patients may guide the clinical practice and scientific research. The aim of this study was to investigate and compare the expression level of ULK1 in 86 paired esophageal squamous cell carcinoma (ESCC) and paracancerous tissues, and to examine the effect of ULK1 expression on the prognosis of ESCC patients.

Inhibitory effect of bone morphogenetic protein-7 on hepatic fibrosis in rats.

Aim: Hepatic cirrhosis is a serious clinical problem caused by the accumulation of extracellular matrix, which can ultimately progress into hepatic failure. Transforming growth factor-beta1 (TGF-β1) plays a pivotal role in extracellular matrix production. Bone morphogenetic protein-7 (BMP-7), as a member of the TGF-β1 superfamily, has been well proved to be capable of reversing renal fibrosis in mice.
