Prognostic significance of MST1R dysregulation in renal cell tumors.

ABSTRACT: Macrophage stimulating 1 receptor (MST1R) is a C-MET proto-oncogene family receptor tyrosine kinase. Promoter methylation patterns determine transcription of MST1R variants as hypermethylation of a region upstream of transcription start site (TSS) is associated with lack of MST1R long transcript (MST1R long) and expression of a short transcript with oncogenic potential. Thus, we aimed to investigate MST1R variant transcript regulation in renal cell tumors (RCT) and assess their prognostic potential. We found, in a series of 120 RCT comprising the four main subtypes (clear cell, papillary and chromophobe renal cell carcinoma, and oncocytoma), that higher methylation levels close to TSS were associated with total MST1R expression levels (MST1R total) in primary tumors (p=0.049) and renal can
