AMBP and cancer: With the aim of providing new information to the poor literature on the potential of bikunin as tissue and circulating biomarker of cancer, we searched through the most recent cancer proteogenomics databases with the in silico platform UALCAN for evaluating bikunin protein expression (Fig. 2) across tumor and normal samples to be compared with its transcript levels (Fig. 3, Table 1), using AMBP as query gene.
