SNP discovery based on transcriptome sequencing of whole blood RNA to find predictive biomarkers for nivolumab in gastric cancer (ESMO 2023)
In comparison between pts with non-HPD and pts with HPD, 306 genes in immune-related GO-Terms were enriched in pts with non-HPD and the median expression value of this genes set was significantly higher in pts with non-HPD; 16 SNPs in 12 genes (COX10-AS1, PASK, DOCK10, CDS2, PASK, CSGALNACT1, ARHGAP26, HLA-DQA1, DIAPH2, NFATC1, ARHGAP6, LCP2, RASA3) were correlated to non-HPD. Conclusions Our translational study demonstrated for the first time that gene expression of whole blood and SNPs as host-related markers can potentially predict response to Nivo in AGC.
