Disrupting CENP-N mediated SEPT9 methylation as a strategy to inhibit aerobic glycolysis and liver metastasis in colorectal cancer.
Colorectal cancer (CRC) is a prevalent malignancy with a high mortality rate, primarily due to liver metastasis. This study explores the role of centromere protein N (CENP-N) in mediating the methylation of septin 9 (SEPT9) and its subsequent effects on aerobic glycolysis and liver metastasis in CRC. We employed in vitro and in vivo experiments, including single-cell RNA sequencing, methylation-specific PCR (MSP), ChIP assays, and various functional assays to assess the impact of CENP-N and SEPT9 on CRC cell proliferation, migration, invasion, and metabolic reprogramming. Our data reveal that CENP-N directly interacts with SEPT9, enhancing its methylation at specific lysine residues. This modification significantly upregulates key glycolytic enzymes, thereby promoting aerobic glycolysis, CRC cell proliferation, and migration. In vivo studies further demonstrate that the CENP-N/SEPT9 axis facilitates liver metastasis of CRC, as confirmed by fluorescence imaging and histological analysis. This study identifies a novel pathway where CENP-N-mediated methylation of SEPT9 drives metabolic reprogramming and metastasis in CRC. These findings suggest potential therapeutic targets for inhibiting CRC progression and liver metastasis, offering new insights into CRC pathogenesis.
期刊介绍:
The Journal''s scope encompasses all aspects of metastasis research, whether laboratory-based, experimental or clinical and therapeutic. It covers such areas as molecular biology, pharmacology, tumor biology, and clinical cancer treatment (with all its subdivisions of surgery, chemotherapy and radio-therapy as well as pathology and epidemiology) insofar as these disciplines are concerned with the Journal''s core subject of metastasis formation, prevention and treatment.
