Hypothesis

The study investigates the role of the TGF-β1 3′Untranslated Region (3′UTR) and its regulation by microRNA-744.

Conclusion

MicroRNA-744 directly targets the short isoform of the TGF-β1 3′UTR, leading to decreased TGF-β1 synthesis.

Supporting Evidence

  • Both long and short TGF-β1 3′UTR variants were expressed in HK-2 cells.
  • Transfection with miR-744 precursor led to a significant decrease in TGF-β1 release.
  • miR-744 was confirmed to repress TGF-β1 synthesis experimentally.

Takeaway

This study shows that a tiny molecule called microRNA-744 can stop a protein called TGF-β1 from being made, which is important for many body processes.

Methodology

The study used luciferase reporter assays and qRT-PCR to analyze the effects of microRNA-744 on TGF-β1 expression.
