The lncRNA encoded by metallothionein 1 J (MT1JP) has been linked to carcinogenesis, and its expression is downregulated in different types of cancer [112–114]. Meanwhile, in vivo and in vitro studies recently showed that MT1JP inhibition increases miRNA-214 gene expressions in BC cells by modulating miRNA-214/RUNX3 Axis [115]. The gene discussed is MT1JP; the disease is cancer.
