Long noncoding RNA ERICD interacts with ARID3A via E2F1 and regulates migration and proliferation of osteosarcoma cells.

Long noncoding RNA ERICD interacts with ARID3A via E2F1 and regulates migration and proliferation of osteosarcoma cells. Cell Biol Int. 2020 Aug 04;: Authors: Arman K, Saadat KASM, Igci YZ, Bozgeyik E, Ikeda MA, Cakmak EA, Arslan A Abstract Long noncoding RNA (lncRNA) dysregulation is known to be taking part in majority of cancers, including osteosarcoma. In one of our previous studies, we showed that lncRNA MEG3 is being regulated by microRNA-664a (miR-664a) suppresses the migratory potential of osteosarcoma cells (U-2OS). We now report a novel lncRNA, namely, ERICD, which is linked to the transcription factor AT-rich interaction domain 3A (ARID3A) in U-2OS cells. We show that ARID3A binds to ERICD and indirectly interacts with each other via the E2F transcription factor 1 (E2F1). Furthermore, small interfering RNA (siRNA)-mediated knockdown of ERICD inhibited cell migration, formation of colonies, and proliferation in U-2OS cells. Overexpression of ARID3A inhibited cell migration, colony formation, and proliferation, whereas siRNA-mediated knockdown of ARID3A promoted cell migration, colony formation, and proliferation. Our findings indicate that ARID3A and lncRNA ERICD have plausible tumor suppressive and oncogenic functions, respectively, in osteosarcoma. Our data demonstrate the converse interaction between ARID3A and lncRNA ERICD that target DNA-binding proteins and dysregulation of their expression through E2F1 augments osteos...
