Introduction:
Yippee Like 1 (YPEL1) is a nuclear protein involved in various cellular processes, including cell cycle regulation, senescence, and mammalian develop-ment. It plays a dual role in cancer, functioning as either an antitumor or tumor-promoting factor.
Methods:
In the current study, via The Cancer Genome Atlas (TCGA) search, we found that YPEL1 is aberrantly expressed in various cancers. High expression of YPEL1 corre-lated with poorer survival outcomes, whereas low expression of YPEL1 was associated with improved overall survival of patients. YT cell lines and gemcitabine-resistant YT cell line (YT/Gem-R) exhibit elevated levels of the YPEL1 protein.
Result:
Furthermore, we determined that knocking down YPEL1 in both YT cell and YT/Gem-R induces apoptosis and autophagy. Additionally, silencing YPEL1 significantly reduced the tumor growth the xenograft model.
Conclusion:
These findings suggest that YPEL1 exhibits the potential for being used as a target for NK / T cell lymphoma treatment.
Insights
Yippee Like 1 (YPEL1) protein shows dual roles in cancer. Silencing YPEL1 in NK/T cell lymphoma models induced cell death and reduced tumor growth, suggesting YPEL1 as a potential therapeutic target.
Area of Science:
- Molecular Biology
- Cancer Research
- Immunology
Background:
- Yippee Like 1 (YPEL1) is a nuclear protein regulating cell cycle, senescence, and development.
- YPEL1 has a dual role in cancer, acting as either an antitumor or tumor-promoting factor.
Purpose of the Study:
- Investigate the role of YPEL1 in various cancers.
- Determine YPEL1's potential as a therapeutic target for NK/T cell lymphoma.
Main Methods:
- Utilized The Cancer Genome Atlas (TCGA) for expression analysis.
- Examined YPEL1 protein levels in YT and gemcitabine-resistant YT (YT/Gem-R) cell lines.
- Performed YPEL1 knockdown experiments in vitro and in vivo xenograft models.
Main Results:
- Aberrant YPEL1 expression was observed across multiple cancers.
- High YPEL1 expression correlated with poorer patient survival, while low expression indicated better outcomes.
