Abstract:
MicroRNAs are known as non-coding RNAs that regulate the expression of target mRNA. Accumulating evidence has indicated that microRNA expression in human malignancies can be utilized as a prognostic marker for patients. However, the prognostic value of miR-650 in human glioma has not been investigated yet. In the present investigation, we have recruited 168 cases glioma specimens and 21 normal control brain specimens. Quantitative real-time PCR was carried out to investigate the expression of miR-650. Kaplan-Meier analysis and Cox's proportional hazards model was used to evaluate the association of miR-650 with prognosis of glioma patients. Results showed that miR-650 expression was increased in glioma compared with normal control specimens (P < 0.001). It was also found that miR-650 expression was related to World Health Organization grade and Karnofsky performance score (KPS) for high expression was more frequently detected in glioma of high grade or low KPS score (P < 0.001). The prognosis of glioma with high miR-650 expression was significantly worse compared with that of glioma with low miR-650 expression. These results proved that miR-650 expression was a significant prognostic indicator in glioma, which may suggest new management of human glioma.
Insights
MicroRNA-650 (miR-650) is elevated in glioma and indicates a worse prognosis for patients. This microRNA may serve as a valuable prognostic marker for glioma management.
Area of Science:
- Molecular Biology
- Oncology
- Genetics
Background:
- MicroRNAs (miRNAs) are non-coding RNAs regulating gene expression.
- Aberrant miRNA expression is linked to various human malignancies.
- The prognostic role of miR-650 in glioma remains uninvestigated.
Purpose of the Study:
- To investigate the expression of miR-650 in human glioma.
- To evaluate the association between miR-650 expression and glioma patient prognosis.
Main Methods:
- Quantitative real-time PCR to measure miR-650 expression in 168 glioma specimens and 21 normal brain tissues.
- Kaplan-Meier analysis and Cox's proportional hazards model to assess prognostic value.
Main Results:
- miR-650 expression was significantly higher in glioma tissues compared to normal controls (P < 0.001).
- Elevated miR-650 correlated with higher World Health Organization grade and lower Karnofsky performance score (KPS) (P < 0.001).
- High miR-650 expression was associated with significantly poorer patient prognosis.
Conclusions:
- miR-650 is upregulated in glioma and serves as a significant independent prognostic indicator.
- miR-650 expression levels can predict patient outcomes in human glioma.
- This finding may inform novel therapeutic strategies for glioma treatment.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
