MIR4435-2HG: A Tumor-associated Long Non-coding RNA

It is well known that the changes in the expression level of LncRNA can affect the progression of tumors, which has caused a great upsurge of research in recent years. Several LncRNAs have been identified to affect a series of cancers and can promote tumor growth, migration, and invasion. In this review, we aim to clarify the pathophysiological functions of LncRNA MIR4435-2 HG in multiple tumors.

By searching the literature through PubMed, this paper summarizes the relationship between MIR4435-2HG and tumor and its role in the occurrence and development of cancer and also explains the specific molecular mechanism of the effect of MIR4435-2HG on cancer.

MIR4435-2HG can function as an oncogene in a variety of cancers. The expression level was reported to be abnormally elevated in a series of cancers, consisting of melanoma, gastric cancer, head and neck squamous cell carcinoma, oral squamous cell carcinoma, lung cancer, cervical cancer, prostate carcinoma, ovarian cancer, breast cancer, hepatocellular carcinoma, clear cell renal cell carcinoma malignant, glioma, and colorectal cancer. Moreover, MIR4435-2HG is related to the poor prognosis of a variety of cancers. MIR4435-2HG can also affect tumor proliferation, invasion, and apoptosis. In addition, MIR4435-2HG can also enhance the metabolic function of myeloid dendritic cells of elite HIV-1 controllers.

MIR4435-2HG affects the development of a variety of cancers. It can act as a clinical marker for early tumor diagnosis and affects tumor-targeted therapy.
