Proteome Analysis of Hepatocellular Carcinoma by Two-dimensional Difference Gel Electrophoresis

Proteome analysis of hepatocellular carcinoma by two-dimensional difference gel electrophoresis: novel protein markers in hepatocellular carcinoma tissues.

Hepatocellular carcinoma (HCC) is a highly malignant tumor, and chronic infection with hepatitis B virus is one of its major risk factors. To identify the proteins involved in HCC carcinogenesis, we used two-dimensional fluorescence DIGE to study the differentially expressed proteins in tumor and adjacent nontumor tissue samples. Samples from 12 hepatitis B virus-associated HCC patients were an...

Evaluation of two-dimensional gel electrophoresis-based proteome analysis technology.

Proteome analysis is most commonly accomplished by a combination of two-dimensional gel electrophoresis (2DE) to separate and visualize proteins and mass spectrometry (MS) for protein identification. Although this technique is powerful, mature, and sensitive, questions remain concerning its ability to characterize all of the elements of a proteome. In the current study, more than 1,500 features...

Analysis of triplet repeat replication by two-dimensional gel electrophoresis.

Expansions of triplet repeats are responsible for more than 15 hereditary neurological disorders in humans. Triplet repeats are fairly stable when the number of elementary units is under approx 30, but become polymorphic in length with a clear bias for expansions when this threshold is exceeded. This results in the rapid addition of hundreds or even thousands of extra repeats and, ultimately, d...

Fluorescence two-dimensional difference gel electrophoresis for biomaterial applications.

Fluorescence two-dimensional difference gel electrophoresis (DiGE) is rapidly becoming established as a powerful technique for the characterization of differences in protein expression levels between two or more conditions. In this review, we consider the application of DiGE-both minimal and saturation labelling-to biomaterials research, considering the challenges and rewards of this approach.
