Abstract:
Prostate cancer (PCa), which is an aggressive malignancy of the male genitourinary system. In the present study, the effects of microRNA-140 (miR-140) on PCa were determined. We transfected miR-140 mimics or negative control into PCa cells, and we used MTT, wound healing, and Transwell assays for determining the capacities of miR-140 in cell proliferation, migration, and invasion, respectively. We also confirmed the relationship between miR-140 and YES proto-oncogene 1 (YES1) using Luciferase reporter assay. The results showed that miR-140 was downregulated in PCa cells and tissues, and overexpression of miR-140 could significantly suppress their capacities of proliferation, migration, and invasion. Moreover, YES1 was shown to be a direct target of miR-140. Moreover, miR-140 expression is negatively correlated with YES1 levels. miR-140 exhibits significant tumor-suppressive effects in PCa by inhibiting YES1. The study indicated that miR-140 and YES1 could be the potential targets for PCa therapy.
Insights
MicroRNA-140 (miR-140) is downregulated in prostate cancer (PCa). Overexpressing miR-140 suppresses PCa cell proliferation, migration, and invasion by targeting YES proto-oncogene 1 (YES1).
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Prostate cancer (PCa) is an aggressive malignancy impacting the male genitourinary system.
- Understanding the molecular mechanisms underlying PCa progression is crucial for developing effective therapies.
Purpose of the Study:
- To investigate the role and effects of microRNA-140 (miR-140) in prostate cancer.
- To determine if miR-140 can be a potential therapeutic target for PCa.
Main Methods:
- PCa cells were transfected with miR-140 mimics or a negative control.
- Cell proliferation, migration, and invasion were assessed using MTT, wound healing, and Transwell assays.
- The interaction between miR-140 and YES proto-oncogene 1 (YES1) was validated using a Luciferase reporter assay.
Main Results:
- miR-140 was found to be downregulated in PCa cells and tissues.
- Overexpression of miR-140 significantly inhibited PCa cell proliferation, migration, and invasion.
- YES1 was identified as a direct target of miR-140, with inverse correlation between their expression levels.
Conclusions:
- miR-140 exerts significant tumor-suppressive effects in prostate cancer by inhibiting YES1.
- Both miR-140 and YES1 represent potential therapeutic targets for prostate cancer treatment.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
