Our findings showcased conspicuous down‐regulation of MATN1‐AS1 in most cancers, particularly in gynaecological oncology, such as cervical cancer (CESC), endometrioid cancer (UCEC), ovarian cancer (OV), and uterine carcinosarcoma (UCS), indicating its possible tumour suppressor role in these malignancies (Figure 1A). The gene discussed is MATN1; the disease is cancer.
