Title: [BRG1 expression in prostate carcinoma by application of tissue microarray].

There was no statistically significant difference in BRG1 gene expression either between PIN and BPH (P > 0.05) or between the groups of the moderate differentiation (the Gleason histologic grading: 5-7) and the lower one (the Gleason histologic grading: 8-10) (P > 0.05).BRG1 may play an important role in the development of prostate carcinoma. Tissue microarray technology, with the advantages of high throughput, conciseness, rapidity, high efficiency, low cost, and nice reproducibility, has significant practical value and broad application prospects in pathology.Read More
