Correlations between the expression of PKCα and Elk-1/MZF-1 in human HCC.IHC analyses and correlations of PKCα and Elk-1/MZF-1 expression in human HCC. The up-panel shows the representative staining results for the samples scored by visual assessment as “weak,” “moderate,” or “strong” on the basis of staining intensity. The label (i.e. F4) at the bottom-left corner of each sample is the serial number of the patients indicated by US Biomax, Inc. (Rockville, MD, USA), and can be viewed at http://www.biomax.us/tissue-arrays/. The numbers of each group classified on the basis of PKCα, Elk-1, or MZF-1 staining intensity or grade are depicted in the down-panel. A positive rating was given to the moderate or strong expression of the genes of interest; otherwise, a negative rating was given. The clinical characteristic grades of I, II, and III were obtained from US Biomax, Inc. *p< 0.05, Pearson's chi-squared test.
