Association Of Upregulation Of Serine And One Carbon Metabolism Genes With Shorter Recurrence-Free And Overall Survival In Urothelial Bladder Cancer (Ubc)
JOURNAL OF CLINICAL ONCOLOGY(2018)
摘要
477Background: Antimetabolites (e.g. methotrexate and gemcitabine) are not frequently used in the treatment of most solid tumors, but are effective in the treatment of UBC. Rapid cancer cell proliferation relies on an abundance of serine-derived one carbon units to support macromolecule synthesis. Specifically, PHGDH, which encodes a key enzyme of de novo serine synthesis, is amplified in breast cancer and in melanoma, and small molecule inhibitors of enzymes in this pathway are in early clinical development. However, the enzymes of serine and one carbon metabolism have not been widely investigated in UBC. Methods: We conducted an observational analysis of The Cancer Genome Atlas UBC cohort, focusing on gene expression data from a targeted panel indicated by Yang, et al. to be involved in serine and one carbon metabolism. Univariate Cox proportional hazard models were utilized to identify genes impacting OS and RFS, and a subsequent multivariate model was employed to control for inter-gene associations. R...
