MiR‐195, located on the chromosome 17p13.1, is a member of the miR‐16/15/195/424/497 family.9 Besides, miR‐195 has been reported to be involved in tumorigenesis as a tumour suppressor.10 High miR‐195 level has been used as a tumour predictor for the prognosis of non‐smoking women with lung adenocarcinoma.11 A bioinformatics website microRNA.org then further revealed that homeobox A10 (HOXA10) was a potential target gene of miR‐195. The gene discussed is HOXA10; the disease is lung adenocarcinoma.
