Abstract:
Gliomas and gastric cancer are more common in China than in Western countries. We performed RNA-seq of 272 gliomas and Exome-seq of 130 gastric cancer patients in the Chinese population. Transcriptome analysis identified 67 in-frame fusion transcripts in gliomas, including 3 recurrent fusion transcripts (FGFR3-TACC3, RNF213-SLC6A11, PTPRZ1-MET). Interestingly, the PTPRZ1-MET (ZM) fusions were mainly found in secondary glioblastoma with an occurrence of 15%. Whole-genome analysis revealed tandem duplication events could contribute to the ZM fusion. Survival analyses indicated ZM fusion as a possible predictive marker in glioma. In the gastric cancer study, we compared somatic mutation and copy number alteration profiles in different subtypes that classified based on anatomic classification (Proximal and Distal) and Lauren classification (Intestinal and Diffuse). Our analyses showed distinct genomic profiles in each subtype.
