Lithium Chloride 184-200 microRNA let-7a-2 Homo sapiens 120-127 21365266-13 2011 Our results suggest that 9-cis-RA, all-trans-RA,lithium chloride and CEBPalpha might play important regulatory roles in let-7a2 gene expression in A549 cells. Lithium Chloride 48-64 microRNA let-7a-2 Homo sapiens 120-127
