In the BAP31_SERPINE2 and SERPINE2_LRP1 parts, to further understand the influence of the colocalization relation on cancer, the biomarker colocalization relation was analyzed, and the outputs were divided into the following parts: BAP31_SERPINE2 and SERPINE2_LRP1, where the former contains BAP31_SERPINE2 (analyzing BAP31 based on SERPINE2), SERPINE2_BAP31 (analyzing SERPINE2 based on BAP31), and the latter contains SERPINE2_LRP1 (analyzing SERPINE2 based on LRP1), LRP1_SERPINE2 (analyzing LRP1 based on SERPINE2). This evidence concerns the gene BCAP31 and cancer.
