Rics; FC: Fold modify. Competing interests A patent was filed (DP, DT, RZ). Authors’ contributions DP, DT, and RZ concepted and made the study. DP, GH, ESch, and AW performed microarray and RT-qPCR experiments. EO performed the multiplexed immunoassays. DP made the microarray bioinformatics and DP, GH, and MK analyzed the data statistically. SA, JS, IB, IV, TVG, SM, NC, and PS recruited patients, collected patient samples and information, and revised the manuscript critically. DP, SA and RZ wrote the manuscript and all authors read and approved the final manuscript.
