"CCL5 and CXCL11 expression were also induced in response to the activation of the PKC pathway and gene silencing experiments indicated that their inducible expression was dependent on RIPK4 and IRF6. Moreover gene reporter assays suggested that RIPK4 induces CCL5 and CXCL11 expression by stimulating the transactivation of their promoters by IRF6."xsd:string
