A previous study identified 95 genes with decreased abundance in striatal tissue in a unilateral 6-OHDA rat model of L-DOPA-induced dyskinesia, of which 19 were included in the salmon module (e.g., Arc, Atf3, Egr1, Egr2, and Nr4a1) and four in the list of the differentially expressed genes (i.e., Klf4, Per1, Cdc24ep4, and Nab2). The gene discussed is KLF4; the disease is Dyskinesia.
