... independently of the presence of AREs (Fig. 6B, lanes 2 and 5). It is possible that in the region located before the AREs, consisting of 343 bp of the 3¢ UTR of the IL-1b transcript, there is a putative ... MCPIP (endogenous and exogenous) starts degradation of IL-1b mRNA and also of its own tran- script. For this reason, the level of mRNA for the wild- typ...
