Role of Sam68 in different types of cancer (Review).

Src‑associated in mitosis 68 kDa protein (Sam68) is a protein encoded by the heteronuclear ribonucleoprotein particle K homology (KH) single domain‑containing, RNA‑binding, signal transduction‑associated protein 1 (known as KHDRBS1) gene in humans. This protein contains binding sites for critical components in a variety of cellular processes, including the regulation of gene expression, RNA processing and cell signaling. Thus, Sam68 may play a role in a variety of diseases, including cancer. Sam68 has been widely demonstrated to participate in tumor cell proliferation, progression and metastasis to be involved in the regulation of cancer stem cell self‑renewal. Based on the body of evidence available, Sam68 emerges as a promising target for this disease. The objectives of the present included summarizing the role of Sam68 in cancer murine models and cancer patients, unraveling the molecular mechanisms underlying its oncogenic potential and discussing the effectiveness of antitumor agents in reducing the malignant effects of Sam68 during tumorigenesis.
