Target
MIR4288
Molecular classification
microRNA, Non-coding RNA, Regulatory RNA, Small RNA
01

Overview

microRNA 4288 (MIR4288) is a small, non-coding RNA molecule in humans, belonging to the microRNA family. Like other miRNAs, MIR4288 regulates gene expression by binding to target messenger RNAs, typically resulting in their degradation or translational inhibition. It has been implicated in prostate cancer, where loss of MIR4288 is associated with increased metastatic and invasive potential due to upregulation of specific target genes (MMP16, ROCK1)[5]. Outside of this role, functional and therapeutic information is limited. As a regulatory molecule rather than a receptor or enzyme, MIR4288 is not a classical drug target but may be useful as a biomarker or in future RNA-based therapies.

02

Mechanism of action

Inhibition of target gene expression via mRNA degradation or translational repression (typical for miRNAs); Specific for MIR4288: direct repression of MMP16 and ROCK1 in prostate cancer

03

Biological functions

Post-transcriptional regulation of gene expressionFine-tuning and buffering of protein outputPotential involvement in cancer cell migration/invasion suppressionOther (general functions associated with miRNAs)
04

Disease associations

Cancer (notably, deletion or reduced expression of miR-4288 is seen in prostate cancer; it directly represses genes involved in metastasis/invasion such as MMP16 and ROCK1)Other (since miRNAs have wide roles in various diseases, but specific evidence for MIR4288 is mainly cancer)
05

Safety considerations

None documented specifically for MIR4288. General challenges for miRNA-based therapies include off-target effects and delivery issues
06

Interacting drugs

None known. MicroRNAs like MIR4288 do not have identified direct drug interactions, but gene therapy or oligonucleotide-based therapeutics (antagomirs, mimics) may be used experimentally
07

Biomarkers

Loss or deletion of MIR4288 may serve as a biomarker of prostate cancer or metastatic potential
