How does Circular RNA expression level play role in pancreatic cancer patients?

The eligible studies were included with the following criteria: studies evaluating the expression of CircRNA profiling in patients with pancreatic cancer, the association between pancreatic cancer cell lines or human samples and CircRNA, their potential role as a biomarker for early diagnosis, and the connection between chemotherapyresistant metastatic pancreatic cancer and CircRNA. 

Circular RNA expression.

Comparing cancer with control.

Biomarkers with prognostic and diagnostic aims.
Quantification of RNA with RT-qPCR and protein with Western blotting (other techniques will be described if identified), quantified through fold change.
