PTCH1 and neoplasm: Recent studies have shown that ncRNA can regulate HH signaling pathway by changing Gli1/2, Smo and Ptch1, such as lncRNA, miRNA and circular RNA (circRNA).507 LncRNA can regulate HH signaling pathway through activation or inhibition, which is related to tumor initiation or progression, chemotherapy resistance, recurrence and other processes.508 The diagnosis or treatment methods based on lncRNA are promising.
