Figure 1. Metrn and Metrnl expression in human tissues (BIGE database).

(A) BIGE expression profiles of METRN and METRNL indicating that METRN is mainly expressed in the CNS while METRNL is not expressed in the CNS but is highly expressed in activated monocytes, skin and mucosal tissues.
(B) Q-PCR was used to confirm the microarray data (BIGE database) pattern of Metrnl expression.
