The results of this study suggest that most of the selected SNPs in angiogenesis-related genes are not associated with survival of mRCC patients after sunitinib therapy or with adverse effects. Only the VEGFR1 SNP rs9582036 showed a statistically significant association with overall survival. The potential of SNPs as prognostic and predictive markers for sunitinib-treated mRCC patients should be finally assessed by prospective studies.

In summary, we determined proteomic and epigenetic differences between non-tumour fibroblasts and TAF of urinary bladder carcinoma and identified specific protein expression patterns as well as miRNA profiles of TAF in comparison with non-tumour fibroblasts. These findings provide more insights into the complex tumour network and a good starting point for the identification of markers for the prediction of tumour development and progression based on specific TAF expression patterns.

Protein profiling using mass spectrometry is suitable for noninvasive detection of rejection-specific changes following kidney transplantation. A specific protein profile enables the prediction of early acute allograft rejection in the immediate postoperative period. A1MG and Hp appear to be reliable rejection biomarkers.
