BIOMARKERS accepted our latest paper on „microRNA signatures in peripheral blood fail to detect acute cellular rejection after liver transplantation“ for publication. Authors are N. Raschzok, A. Reutzel-Selke, R. Schmuck, L. Tannus, M. Morgul, C. Dietel, A. Leder, B. Struecker, S. Lippert, H. Sallmon, M. Schmelzle, M. Bartels, S. Jonas, J. Pratschke, and I.M. Sauer.

We investigated whether microRNA signatures in whole blood samples are associated with acute cellular rejection (ACR) after liver transplantation. Blood samples were collected using Paxgene technology and analyzed by microarrays and qRT-PCR. microRNA signatures failed to distinguish between 19 patients with ACR and 16 controls. Let-7b-5p and let-7c were up-regulated in a subgroup of patients with ACR during the 6th and 7th postoperative day but failed in an independent validation of 20 patients. microRNA signatures in whole blood processed by Paxgene technology are not suited for detection of ACR after liver transplantation.
