MicroRNA 1237 (MIR1237)

Target
MIR1237
Molecular classification
microRNA (miRNA), Non-coding RNA
01

Overview

MicroRNA 1237 is a short (20-24 nucleotide) non-coding RNA molecule that regulates gene expression at the post-transcriptional level by guiding the RNA-induced silencing complex (RISC) to target mRNAs, resulting in their translational inhibition or degradation. It has context-dependent disease associations, notably acting as a tumor marker in oral squamous cell carcinoma with upregulation linked to poor prognosis and recurrence, and as a tumor suppressor in gastric cancer where it is epigenetically silenced via DNA methylation. MIR1237 is predicted or validated to regulate genes critical for cancer progression, including ERBB3 and CCND2, impacting cell proliferation, migration, and invasion. Its expression pattern and epigenetic status are being explored for cancer diagnosis, prognosis, and potential future therapeutic targeting.

Mechanism of action

Post-transcriptional gene silencing via imperfect base pairing with target mRNAs; Indirect modulation of cellular pathways (e.g., PI3K-AKT signaling, transcriptional misregulation in cancer); Downregulation of specific cancer-related genes (e.g., ERBB3, CCND2)

03

Biological functions

Post-transcriptional regulation of gene expressionRegulation of stability and translation of mRNAsModulation of cell proliferation, migration, and invasion (inhibition in cancer contexts)
04

Disease associations

Cancer (reported in oral squamous cell carcinoma, gastric cancer, colorectal cancer, acute lymphoblastic leukemia)Tumorigenesis and tumor progression (as an onco-miR or tumor suppressor depending on context)Disease prognosis (e.g., poor prognosis signature in oral cancer, tumor recurrence prediction)
05

Safety considerations

Lack of established safety profile for direct targeting; general concerns include off-target effects and delivery specificity for miRNA-based therapiesPotential risks exist with miRNA modulating therapies due to broad gene regulatory networks
06

Biomarkers

Overexpression in oral squamous cell carcinoma (OSCC), especially in early-stage and low tumor depth, associated with tumor recurrence and poor prognosisMethylation status in gastric cancer as a marker for epigenetic silencing
