The non-metabolic function of 6PGD coordinates CCNA2 and HMGA2 expression to drive colorectal cancer progression and drug response.
Emerging evidence demonstrates that the metabolic and non-metabolic functions of metabolic enzymes play a key role in tumorigenesis and progression. 6-phosphogluconate dehydrogenase (6PGD) is a key metabolic enzyme in the pentose phosphate pathway (PPP), which displays aberrant expressions and functions in cancer. However, whether 6PGD serves non-metabolic functions in regulating cancer progression and drug response has not been reported. Here, we found that highly expressed 6PGD contributes to colorectal cancer (CRC) tumor growth and tumor metastasis. Mechanistically, 6PGD binds to ALKBH5 and inhibits its activity through the non-metabolic activity of 6PGD; this increases m6A modification levels and the stability of MDM2 mRNA and decreases the p53 protein stability, subsequently activating the expression of CCNA2 and HMGA2, which are responses to CRC tumor growth and tumor metastasis. Collectively, these findings reveal the multi-functionality of 6PGD in promoting CRC tumor growth, tumor metastasis, and drug responses through its non-metabolic activity.
期刊介绍：
The Journal of Experimental & Clinical Cancer Research is an esteemed peer-reviewed publication that focuses on cancer research, encompassing everything from fundamental discoveries to practical applications.
We welcome submissions that showcase groundbreaking advancements in the field of cancer research, especially those that bridge the gap between laboratory findings and clinical implementation. Our goal is to foster a deeper understanding of cancer, improve prevention and detection strategies, facilitate accurate diagnosis, and enhance treatment options.
We are particularly interested in manuscripts that shed light on the mechanisms behind the development and progression of cancer, including metastasis. Additionally, we encourage submissions that explore molecular alterations or biomarkers that can help predict the efficacy of different treatments or identify drug resistance. Translational research related to targeted therapies, personalized medicine, tumor immunotherapy, and innovative approaches applicable to clinical investigations are also of great interest to us.
We provide a platform for the dissemination of large-scale molecular characterizations of human tumors and encourage researchers to share their insights, discoveries, and methodologies with the wider scientific community.
By publishing high-quality research articles, reviews, and commentaries, the Journal of Experimental & Clinical Cancer Research strives to contribute to the continuous improvement of cancer care and make a meaningful impact on patients' lives.
