Additionally, we found that the expression levels between CDC42 and CACNA2D2, LARS2 and REG1CP were significantly correlated in the tumor samples (Spearman's correlation r = −0.2507655 and p-value = 1.84e–10 for CACNA2D2; r = −0.2097521 and p-value 1.207e–07 for LARS2 and r = 0.08323233 and p-value = 0.03705 for REG1CP) in agreement with our array data in SW620 cells. This evidence concerns the gene REG1CP and neoplasm.
