DICER1 and osteosarcoma: Similar to other studies using different cell lines (Bandiera et al., 2011a,b; Das et al., 2012; Sripada et al., 2012; Tattikota et al., 2013; Zhang et al., 2014; Wang et al., 2015; Bose et al., 2020), we found that both components of the miRNA pathway, Dicer and Ago2, can be located in the mitochondria of osteosarcoma 143B cybrids.
