The second correlation in this category was found between RARB SN1 in blood and ACIN1 SN1 (ρ = 0.536, p = 0.005) and SN3 (ρ = 0.504, p = 0.009) in pancreatic tumor tissue and, reciprocally, ACIN1 SN1 (ρ = −0.664, p<0.001) and SN3 (ρ = −0.433, p = 0.027) in blood correlated with RARbeta SN1 in pancreatic tumor tissue. The gene discussed is ACIN1; the disease is pancreatic neoplasm.
