Research progress of long noncoding RNA in gastric cancer

Non-coding RNA is a kind of RNA, without protein coding function, which plays an important role in the occurrence and development of tumors. Studies show that long non-coding RNA, circRNA and pseudogenes play tumor-promoting and anti-tumor effects in the occurrence and development of gastric cancer, which can regulate all kinds of malignant biological behaviors of gastric cancer such as cell proliferation, apoptosis, invasion and metastasis through internal competitive RNA (ceRNA) mechanism. In addition, studies show that small interfering RNA and Piwi-interacting RNA may also be related to the occurrence and development of gastric cancer. Key words: Stomach neoplasms; Non-coding RNA
