For statistical analysis, the predominant Fuhrman nuclear grade (the grade occupying the largest area) was used to represent each tumor.In cases with Fuhrman grade ≥2, the ratio of visfatin mRNA in peri-tumor fat versus peri-normal fat was higher in comparison with that in cases with Fuhrman grade 1 (Figure 1). The gene discussed is NAMPT; the disease is neoplasm.
