PMID	Cancer type	Relation to immunity	Evidence sentences
27685836	Lung Carcinoma	Promote immunity (T cell function); essential for immunotherapy	It is therefore essential to engineer therapeutic interventions by which T cell reactivity against tumor cells is selectively enhanced (i.e., "focused cancer immunotherapy") based on tumor antigens that are specifically expressed in the tumor of a certain cancer and in many patients with this cancer. This analysis indicated that gelsolin and inter-alpha-trypsin inhibitor heavy chains were specifically and frequently detected (at a frequency higher than 80%), and that phosphoproteins (VENTX, VCIP135) were also specifically present in the ICs of lung cancer patients.

Content	High-throughput screening data (e.g. CRISPR-Cas9, shRNA and RNAi) for T cell-mediated killing. Genetic screen techniques can identify mechanisms of tumor cell resistance (e.g., PTPN2) and sensitivity (e.g., APLNR) to killing by cytotoxic T cells, the central effectors of anti-tumor immunity. After comprehensively searching, eight groups of screening data sets were collected in the current database. In this tab, users can check whether their selected genes cause resistance or increase sensitivity to T cell-mediated killing in various data sets.

Content	Transcriptomic and genomic profiling of pre-treated tumor biopsies from responders and non-responders to immunotherapy. These data were used to identify signatures and mechanisms of response to checkpoint blockade (e.g., anti-PDL1 and anti-PD1). One example is that mutations in the gene PBRM1 benefit clinical survival of patients with clear cell renal cell carcinoma. After comprehensively searching, we collected 5 and 6 of transcriptomic and genomic data sets, respectively. In this tab, users can check whether their selected genes have significant difference of expression or mutation between responders and non-responders in various data sets. > Expression difference between responders and non-responders > Mutation difference between responders and non-responders
