Test weight is an important trait in maize breeding. Understanding the genetic mechanism of test weight is important for effective selection of maize test weight improvement. In this study, quantitative trait loci (QTL) for maize test weight were identified. In the years 2007 and 2008, a F2:3 population along with the parents Chang7-2 and Zheng58 were(More)
Rapamycin (RAPA) inhibits tumor growth and angiogenesis in hepatocellular carcinoma (HCC). The molecular mechanism underlying the antitumoral effects of RAPA remains unclear. Here we established a chemical-induced rat HCC model to investigate the signaling pathways mediating RAPA’s antitumor activity. We found that RAPA exposure significantly diminished(More)
The docosahexaenoic (DHA), a ω-3 fatty acid, could play a beneficial inhibition of the incidence and progress of a series of human diseases including cancer. It has been report that DHA is involved in cell apoptosis. Recent studies show that the signal transduction pathway links with bcl-2, bax, caspase-3 and MMP-9 molecules. Therefore, we tested the(More)
Available literature on the effects of interferon (IFN) treatment on development and progression of hepatocellular carcinoma (HCC) in patients with chronic virus infection reports controversial results. The primary objective of this meta-analysis was to evaluate the effect of IFN on HCC risk in patients with chronic hepatitis C virus (HCV) or hepatitis B(More)
Occurrence of second primary tumors and metastasis remains the major obstacles to prolonged survival of patients with primary hepatocellular carcinoma (HCC). A somatostatin analogue, octreotide, has been previously reported to inhibit the growth of human HCC xenografts in nude mice through its anti-angiogenic activity. It is therefore important to(More)
Extracellular matrix protein 1 (ECM1) is a glycoprotein involved in a number of biologic processes. To investigate the expression of ECM1 in hepatocellular carcinoma (HCC) and determine its correlation with tumor progression and prognosis, the expression levels of ECM1 in three HCC and one normal liver cell lines, tumor, and corresponding adjacent tissues(More)
BACKGROUND Although hepatectomy is often performed with the Pringle maneuver, the problem of hepatic ischemia-reperfusion injury (HIRI) can also be serious. Thus, the present study was designed to investigate the protective effect of S-adenosylmethionine (SAMe) on HIRI, especially for patients with hepatocellular carcinoma (HCC) associated with chronic(More)
BACKGROUND To examine the expression of signal transducer and activator of transcription 3 (STAT3) and its activated form (p-STAT3), Twist, and E-cadherin in hepatocellular carcinoma (HCC), and explore their correlations with HCC progression and prognosis. MATERIALS AND METHODS The expression profiles of STAT3, p-STAT3, Twist, and E-cadherin were assessed(More)
Vasculogenic mimicry (VM), including tubular VM and patterned matrix VM, has been generally recognized as a new pattern of tumor neovascularization. Pilot studies of tubular VM showed that it was present in hepatocellular carcinoma (HCC) and associated with poor clinical prognosis. However, whether patterned matrix VM is clinically significant in HCC is(More)
Versican, a large extracellular matrix proteoglycan, accumulates both in tumor stroma and cancer cells. It participates in cell adhesion, migration, and angiogenesis, all features of invasion and metastasis. However, the mechanism(s) whereby versican promotes cancer invasion and metastasis is not yet fully understood. A recent study has documented that(More)
