Artigo Bioinformatics analysis of the human surfaceome reveals new targets for a variety of tumor types(Hindawi, 2016-10-18) Fonseca, André L.; Silva, Vandeclécio Lira da; Fonseca, Marbella M.; Meira, Isabella Tanus Job e; Silva, Thayná Emília Oliveira; Kroll, José Eduardo; Ribeiro-dos-Santos, André M.; Freitas, Cléber R.; Furtado, Raimundo; Souza, Jorge Estefano Santana de; Ferreira, Beatriz Stransky; Souza, Sandro José deIt is estimated that 10 to 20% of all genes in the human genome encode cell surface proteins and due to their subcellular localization these proteins represent excellent targets for cancer diagnosis and therapeutics. Therefore, a precise characterization of the surfaceome set in different types of tumor is needed. Using TCGA data from 15 different tumor types and a new method to identify cancer genes, the -score, we identified several potential therapeutic targets within the surfaceome set. This allowed us to expand a previous analysis from us and provided a clear characterization of the human surfaceome in the tumor landscape. Moreover, we present evidence that a three-gene set—WNT5A, CNGA2, and IGSF9B—can be used as a signature associated with shorter survival in breast cancer patients. The data made available here will help the community to develop more efficient diagnostic and therapeutic tools for a variety of tumor typesArtigo Bioinformatics Analysis of the Human Surfaceome Reveals New Targets for a Variety of Tumor Types(2016-10-18) Fonseca, André L.; Silva, Vandeclécio L. da; Fonseca, Marbella M.; Meira, Isabella T.

In this study, we provide a genomewide screen for CT genes with the identification of 745 putative CT genes. Comparison with a set of known CT genes shows that 201 new CT genes were identified. Integration of gene expression and clinical data led us to identify dozens of CT genes associated with either good or poor prognosis. For the CT genes related to good prognosis, we show that there is a direct relationship between CT gene expression and a signal for CD8+ cells infiltration for some tumor types, especially melanoma
