Description Breast cancer, as the malignancy with the highest incidence rate and mortality rate in women, seriously threatens human life and health. Pieces of evidence have suggested that long non-coding RNAs (lncRNAs) possess important effects on regulating the occurrence and development of breast cancer. In addition, microRNA-22-3p (miR-22-3p) expression was down-regulated in breast cancer tissues and cell lines, and negatively associated with lncRNA MIR4435-2HG expression. Over-expression of miR-22-3p obviously inhibited the viability, proliferation, migration, invasion and EMT of breast cancer cell lines. Furthermore, Transmembrane protein 9 domain family member B (TMEM9B) was up-regulated in breast cancer tissues and cell lines and negatively associated with miR-22-3p expression. Finally, TMEM9B inhibition partially restored the effects of lncRNA MIR4435-2HG/miR-22-3p on the viability, proliferation, migration, invasion and EMT of breast cancer cell lines. LncRNA MIR4435-2HG potentially played a tumor-promoting role in the occurrence and development of breast cancer, which might be achieved by regulating the miR-22-3p/TMEM9B axis.
