Many studies have explored the regulatory mechanism of lncRNA HOXC13-AS in different types of cancer (Figure 5), including nasopharyngeal carcinoma (Gao et al., 2019), breast cancer (Li et al., 2019a), oral squamous cell carcinoma (Li et al., 2020), glioma (Liu et al., 2019), and cervical cancer (Wang et al., 2021). The gene discussed is HOXC13; the disease is cervical carcinoma.
