miR-149 in Human Cancer: A Systemic Review

Area of Science:

• Molecular Biology
• Genetics
• Oncology

Background:

• MicroRNAs (miRNAs) are small noncoding RNAs regulating gene expression post-transcriptionally.
• miRNAs play significant roles in cancer initiation and progression.
• Aberrant regulation of miR-149 is observed across various tumor types.

Purpose of the Study:

• To provide a comprehensive overview of miR-149.
• To summarize the critical roles of miR-149 in cancer.
• To establish a foundation for future research on miR-149 in oncology.

Main Methods:

• Literature review of studies on miR-149 and cancer.
• Analysis of reported functions and dysregulation of miR-149 in tumorigenesis.
• Synthesis of current knowledge on miR-149's involvement in various cancers.

Main Results:

• miR-149 is confirmed to be aberrantly regulated in multiple cancers.
• miR-149 exhibits critical roles in the complex processes of tumorigenesis and cancer progression.
• Evidence suggests miR-149 acts as a key regulator in the tumor microenvironment.

Conclusions:

• miR-149 is a significant microRNA with critical implications in cancer.
• Understanding miR-149's functions is essential for cancer research.
