Of interest, serum 25(OH)D was reversely correlated with serum ICAM (r = −0.25, P < 0.05), VCAM (r = −0.23, P < 0.05), MCAM (r = −0.27, P < 0.05), LAMA4 (r = −0.23, P < 0.05) and EpCAM (r = −0.25, P < 0.05) in RCC patients (Table 4). This evidence concerns the gene LAMA4 and renal cell adenocarcinoma.
