According to microarray and RT-PCR data, hsa_circ_0043256 is upregulated in NSCLC cells in response to cinnamaldehyde treatment and might inhibit cell proliferation and induce apoptosis via the hsa_circ_0043256/miR-1252/ITCH axis in response to cinnamaldehyde [41]. The gene discussed is ITCH; the disease is non-small cell lung carcinoma.
