RESUMO
PURPOSE: Circ-SHPRH is a circular RNA that can regulate the expression of target genes by sponging microRNAs (miRNAs) or translating tumor suppressor proteins. Recent studies have suggested that circ-SHPRH may play a role in the development of tumors and cancers. Hence, this paper aimed to review the biological characteristics, molecular mechanisms, and potential clinical significance of circ-SHPRH in a variety of tumors and to evaluate its potential as a new diagnostic and prognostic biomarker. METHODS: Numerous experiments were performed regarding the abnormal expression of circ-SHPRH in a variety of tumors, including hepatocellular carcinoma, gastric carcinoma, non-small cell lung cancer, osteosarcoma, colorectal cancer, cholangiocarcinoma, pancreatic ductal adenocarcinoma, retinoblastoma, and glioblastoma. RESULTS: Upregulation of circ-SHPRH reportedly inhibits tumor cell proliferation, migration, and invasion, leading to the inhibition of tumor development. The clinicopathological parameters and the functional characteristics of circ-SHPRH in multiple human tumors and cancers were summarized. Circ-SHPRH functions as a tumor suppressor gene and has great potential as a diagnostic and prognostic biomarker for different types of cancer.
RESUMO
Circular RNAs belong to the class of non-coding RNA molecules, though surprisingly some of them have protein-coding potentials. However, the circular RNA circ-SHPRH is known to code for an unusual protein known as SHPRH-146aa. However, the molecular level details of the protein are not yet identified. It was proposed that the protein has its role in glioblastoma. Therefore, in this work, an attempt was made to decipher the various structural features of SHPRH-146aa. The binding interactions of the protein SHPRH-146aa with its partner protein DTL were also analyzed. The main aim of the work was to decipher the characteristics features of this unusual protein and the region on SHPRH-146aa that would form different types of non-covalent binding interactions both among itself as well as with its binding partner. In this work, we tried to elucidate the various structural and physico-chemical features of the protein as well as its mode of interactions with its binding partner. The study would therefore pave the pathway to design future wet lab experiments to delineate the appropriate structural features of the protein as well as its association with glioblastoma and neuro-degenerative diseases.
