Abstract:
Long noncoding RNAs (lncRNAs) are recognized as a class of critical regulators in various tumors. Recently, lncRNA LSINCT5 has been reported to promote the progression of bladder cancer, ovarian cancer, gastric cancer, and breast cancer. However, the biological function of LSINCT5 remains elusive in osteosarcoma (OS). In our study, we found that LSINCT5 was significantly upregulated in OS tissues than in adjacent normal tissues. Additionally, the expression of LSINCT5 was inversely associated with the prognosis of patients with OS. LSINCT5 knockdown dramatically inhibited OS cell proliferation in vitro and tumor growth in vivo. Mechanistic exploration revealed that LSINCT5 interacted with EZH2 to suppress the expression of APC, a negative regulator of the Wnt/β-catenin pathway. Moreover, rescue assays suggested that LSINCT5 exerted oncogenic roles by partially inhibiting APC expression in OS. In summary, our study demonstrated that LSINCT5 was a promising candidate for OS prognosis and therapy.

What is Gene Expression?
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...
