Schema of CARMN’s role in triple negative breast cancer: Triple negative breast cancer cells have low level of CARMN. CARMN can inhibit breast cancer and sensitize chemotherapy by regulating many essential pathways and processes. CARMN functions partially by producing embedded miR143-3p which binds with MCM5. MCM5 acts as member of DNA replication initiation factor MCM complex, which combines with ORC and licenses DNA replication. Suppressing of MCM5 by CARMN inhibits normal DNA replication, leading to inhibited tumor growth and higher cisplatin sensitivity. Cisplatin can upregulate CARMN to cause cell apoptosis as a feedback. cDDP: cisplatin; ORC: origin recognition complex
