Abstract:
Long non-coding RNAs (lncRNAs) have attracted significant attention for their role in tumor initiation and progression. Specifically, studying lncRNA small nucleolar RNA host genes (lncSNHGs) has opened up new possibilities for the treatment of osteosarcoma (OS). This review aims to give a thorough overview of the state of research on the biological roles, molecular mechanisms, and expression of the lncRNA SNHG family in OS. Through an extensive analysis, it is demonstrated that members of the SNHG family exhibit dysregulated expression patterns in OS. These dysregulations affect multiple oncogenic processes, including tumor proliferation, metastasis, apoptosis, autophagy, and chemotherapy resistance. The lncRNA SNHG family promises to identify novel strategies and targets for diagnosing, treating, and prognosis OS.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
