MILIP and nonpapillary renal cell carcinoma: Of the two annotated isoforms of MILIP (Supplementary Fig. 1d), the longer isoform (MILIP-001) was readily detected, whereas the shorter isoform (MILIP-002) was barely measurable with exon-specific primers in ccRCC cells (Supplementary Fig. 1d, e), consistent with the notion that the longer isoform is the major functional variant of MILIP [19].
