However, the CDR1as expression level is altered in some tumors, pulmonary fibrosis, or myocardial infarction, and we speculate that the regulatory effect of CDR1as is extensive but not specific, as a result, the changes in CDR1as expression are not unique to a single disease; however, CDR1as may be valuable for determining the degree of malignancy and prognosis of tumors. The gene discussed is LINC00632; the disease is myocardial infarction.
