ERBB2 and neoplasm: Guo et al. evaluated the UCA1 expression to be upregulated and enhance tumor development in the established transcriptional tumor suppressor ARID1A-depleted JIMT1 (Her2+), HCC1937, MDA-MB-468 (both triple-negative), and MCF7 cells, whereas the inhibition of UCA1 by ARID1A suppressed their proliferation and invasion abilities.
