MIR8084
Molecular classification
MicroRNA (miRNA), Non-coding RNA, Regulatory RNA
01

Overview

MicroRNA 8084 (MIR8084) is a small, non-coding RNA molecule (miRNA) that regulates gene expression post-transcriptionally, mainly by promoting mRNA degradation or repressing translation. MIR8084 is upregulated in breast cancer, where it acts as an oncogene (“oncomiR”) by promoting cell proliferation, migration, invasion, and suppressing apoptosis. Its oncogenic effects are linked to downregulation of the tumor suppressor *ING2*, as well as activation of signaling pathways such as ERK1/2 and AKT and suppression of the p53-BAX apoptosis axis. MIR8084 is detectable in serum and tumor tissue, suggesting utility as a non-invasive diagnostic or prognostic biomarker in breast cancer. Although it is a potential therapeutic target, there are no current drugs directly approved for MIR8084, and more research is required into risk and clinical applicability[1].

Biological functions

Regulation of gene expression (post-transcriptional)Promotion of cell proliferationInhibition of apoptosisEnhancement of cell migration and invasion (epithelial–mesenchymal transition/EMT)Tumorigenesis
03

Disease associations

Cancer, specifically breast cancer (oncomiR)Potentially involved in other conditions such as osteoporosis and epithelial ovarian tumor (as suggested by limited early studies)
04

Safety considerations

Therapeutic targeting of microRNAs may have broad off-target effects due to their regulation of multiple genes.Lack of clinical trials or safety data for direct targeting of miR-8084 in patients (as of current research)
05

Biomarkers

Diagnostic biomarker for breast cancer (detectable and elevated in serum and tissue of breast cancer patients)
