Exosomal microRNA-214 expression and its prognostic significance in non-small cell lung cancer patients
Altered miRNAs expression have been found to be linked with several solid tumors and expression levels detected in serum, plasma or other body fluids. Thus the current study aimed to explore the serum based exosomal microRNA-214 expression in NSCLC patients.Present study recruited 100 NSCLC case and...

Study concluded higher serum based miRNA-214 expression is associated with advancement of disease and it suggested that serum based miRNA-214 expression could be used as prognostic and poor survival indicator in NSCLC patients.
