Aims: microRNAs (miRNAs) are a class of small noncoding RNAs that can act as key
modulators in tumorigenesis-related genes. Specifically, it has been suggested that miR-21 …

Purpose: Among more than 500 microRNAs, microRNA-21 (miR-21) is known to act as an
oncogene. The aim of this study was to investigate the significance of miR-21 expression …

Background MicroRNAs (miRNAs) have been shown to be involved in the initiation and
progression of cancers in the literature. In this study, we aimed to evaluate the …

Objective: The recently discovered microRNAs (miRNAs) are non-protein-coding,
endogenous small RNAs. The aim of this study was to investigate the relationship between …

Purpose Therapeutic decisions in breast cancer are increasingly guided by prognostic and
predictive biomarkers. Non-protein-coding microRNAs (miRNAs) have recently been found …

Introduction MicroRNAs (miRNAs) are a class of small non-coding RNAs (20 to 24
nucleotides) that post-transcriptionally modulate gene expression. A key oncomir in …

Breast cancer is characterized by an elevated capacity for tumor invasion and lymph node
metastasis, but the cause remains to be determined. Recent studies suggest that microRNAs …

Growing evidence suggests microRNAs (miRNAs) have an important role in tumorigenesis.
MicroRNA-21 (miR-21) is up-regulated in many malignant tumors, including breast cancer …

Abstract MicroRNA-21 (miR-21) located on 17q23. 1 expressed in breast cancer has anti-
apoptotic ability and causes tumor cell growth. It is also involved in functions such as signal …

OBJECTIVE: MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene
expression at the posttranscriptional level. Some miRNAs, including let-7a and miR-195 …
