Abstract:
Prostate cancer (PCa) is one of the most common cancers and is the second leading cause of mortality in men. Studies exploring novel therapeutic methods are urgently needed. FAM107A, a coding gene located in the short arm of chromosome3, is generally downregulated in PCa and is associated with a poor prognosis. However, the downregulation of FAM107A in PCa and the mechanism of its action remain challenging to determine. This investigation found that downregulation of FAM107A expression in PCa was caused by hypermethylation of CpG islands. Furthermore, DNA methyltransferase 1 (DNMT1) was involved in maintaining hypermethylation. Mechanistically, overexpression of FAM107A inhibits tumor cell proliferation, migration, invasion and promotes apoptosis through the FAK/PI3K/AKT signaling pathway, indicating that FAM107A may be a molecular brake of FAK/PI3K/AKT signaling, thus limiting the active state of the FAK/PI3K/AKT pathway. These findings will contribute to a better understanding of the effect of FAM107A in PCa, and FAM107A may represent a new therapeutic target for PCa.
Insights
FAM107A gene downregulation in prostate cancer (PCa) is caused by hypermethylation. Overexpressing FAM107A inhibits PCa cell growth and migration via the FAK/PI3K/AKT pathway, suggesting it as a potential therapeutic target.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Prostate cancer (PCa) is a leading cause of cancer mortality in men, necessitating novel therapeutic strategies.
- The FAM107A gene is frequently downregulated in PCa, correlating with poor prognosis, but its regulatory mechanisms and functional impact are unclear.
Purpose of the Study:
- To investigate the mechanisms underlying FAM107A downregulation in prostate cancer.
- To elucidate the functional role of FAM107A in PCa progression and its associated signaling pathways.
Main Methods:
- Analysis of FAM107A expression levels in PCa tissues.
- Investigation of CpG island methylation and DNA methyltransferase 1 (DNMT1) involvement.
- Functional assays assessing the impact of FAM107A overexpression on tumor cell proliferation, migration, invasion, and apoptosis.
- Exploration of the FAK/PI3K/AKT signaling pathway.
Main Results:
- FAM107A downregulation in PCa is attributed to hypermethylation of its CpG islands, with DNMT1 maintaining this hypermethylation.
- FAM107A overexpression significantly inhibits PCa cell proliferation, migration, and invasion.
- FAM107A promotes apoptosis in PCa cells.
- FAM107A functions as a molecular brake on the FAK/PI3K/AKT signaling pathway.
Conclusions:
- FAM107A downregulation in prostate cancer is epigenetically regulated by DNA hypermethylation.
- FAM107A exerts tumor-suppressive effects by inhibiting cell proliferation, migration, and invasion through the FAK/PI3K/AKT pathway.
- FAM107A represents a promising novel therapeutic target for prostate cancer treatment.
