Furthermore, correlation analysis of mRNA receptor expression levels quantified in FF and FFPE material of the same tumor, resulted in a significant positive correlation for both GRPR (Spearman rs = 0.77, p = 0.0034) and SSTR2 (Spearman rs = 0.72, p = 0.0082) (Fig 1C+1E). The gene discussed is GRPR; the disease is neoplasm.
