In this study, we identify a subset of human melanomas that have loss-of-function mutations in ATR, a kinase that recognizes and repairs UV-induced DNA damage and is required for cellular proliferation. ATR mutant tumors exhibit both the accumulation of multiple mutations and the altered expression of inflammatory genes, resulting in decreased T cell recruitment and increased recruitment of macrophages known to spur tumor invasion. Taken together, these studies identify a mechanism by which melanoma cells modulate the immune microenvironment to promote continued growth.","tracks":[{"project":"kaiyin_test","denotations":[{"id":"T1","span":{"begin":0,"end":3},"obj":"Gene"},{"id":"T2","span":{"begin":4,"end":13},"obj":"Var"},{"id":"T3","span":{"begin":14,"end":21},"obj":"PosReg"},{"id":"T5","span":{"begin":26,"end":32},"obj":"MPA"},{"id":"T4","span":{"begin":36,"end":51},"obj":"Disease"},{"id":"T6","span":{"begin":133,"end":142},"obj":"Var"},{"id":"T7","span":{"begin":166,"end":174},"obj":"Reg"},{"id":"T8","span":{"begin":175,"end":186},"obj":"MPA"},{"id":"T9","span":{"begin":200,"end":208},"obj":"NegReg"},{"id":"T10","span":{"begin":213,"end":259},"obj":"MPA"},{"id":"T11","span":{"begin":464,"end":467},"obj":"Gene"},{"id":"T12","span":{"begin":468,"end":474},"obj":"Var"},{"id":"T13","span":{"begin":597,"end":606},"obj":"NegReg"},{"id":"T14","span":{"begin":607,"end":625},"obj":"MPA"},{"id":"T15","span":{"begin":630,"end":639},"obj":"PosReg"},{"id":"T16","span":{"begin":640,"end":666},"obj":"MPA"}],"relations":[{"id":"R1","pred":"ThemeOf","subj":"T1","obj":"T2"},{"id":"R10","pred":"CauseOf","subj":"T12","obj":"T13"},{"id":"R11","pred":"ThemeOf","subj":"T14","obj":"T13"},{"id":"R12","pred":"CauseOf","subj":"T12","obj":"T15"},{"id":"R13","pred":"ThemeOf","subj":"T16","obj":"T15"},{"id":"R2","pred":"CauseOf","subj":"T2","obj":"T3"},{"id":"R3","pred":"ThemeOf","subj":"T5","obj":"T3"},{"id":"R4","pred":"ThemeOf","subj":"T4","obj":"T5"},{"id":"R5","pred":"CauseOf","subj":"T6","obj":"T7"},{"id":"R6","pred":"ThemeOf","subj":"T8","obj":"T7"},{"id":"R7","pred":"CauseOf","subj":"T6","obj":"T9"},{"id":"R8","pred":"ThemeOf","subj":"T10","obj":"T9"},{"id":"R9","pred":"ThemeOf","subj":"T11","obj":"T12"}],"attributes":[{"subj":"T1","pred":"source","obj":"kaiyin_test"},{"subj":"T2","pred":"source","obj":"kaiyin_test"},{"subj":"T3","pred":"source","obj":"kaiyin_test"},{"subj":"T5","pred":"source","obj":"kaiyin_test"},{"subj":"T4","pred":"source","obj":"kaiyin_test"},{"subj":"T6","pred":"source","obj":"kaiyin_test"},{"subj":"T7","pred":"source","obj":"kaiyin_test"},{"subj":"T8","pred":"source","obj":"kaiyin_test"},{"subj":"T9","pred":"source","obj":"kaiyin_test"},{"subj":"T10","pred":"source","obj":"kaiyin_test"},{"subj":"T11","pred":"source","obj":"kaiyin_test"},{"subj":"T12","pred":"source","obj":"kaiyin_test"},{"subj":"T13","pred":"source","obj":"kaiyin_test"},{"subj":"T14","pred":"source","obj":"kaiyin_test"},{"subj":"T15","pred":"source","obj":"kaiyin_test"},{"subj":"T16","pred":"source","obj":"kaiyin_test"}]},{"project":"name_no","denotations":[{"id":"T1","span":{"begin":0,"end":3},"obj":"Gene"},{"id":"T2","span":{"begin":4,"end":13},"obj":"Var"},{"id":"T3","span":{"begin":14,"end":21},"obj":"PosReg"},{"id":"T5","span":{"begin":26,"end":32},"obj":"MPA"},{"id":"T4","span":{"begin":36,"end":51},"obj":"Disease"},{"id":"T6","span":{"begin":133,"end":142},"obj":"Var"},{"id":"T7","span":{"begin":166,"end":174},"obj":"Reg"},{"id":"T8","span":{"begin":175,"end":186},"obj":"MPA"},{"id":"T9","span":{"begin":200,"end":208},"obj":"NegReg"},{"id":"T10","span":{"begin":213,"end":259},"obj":"MPA"},{"id":"T11","span":{"begin":464,"end":467},"obj":"Gene"},{"id":"T12","span":{"begin":468,"end":474},"obj":"Var"},{"id":"T13","span":{"begin":597,"end":606},"obj":"NegReg"},{"id":"T14","span":{"begin":607,"end":625},"obj":"MPA"},{"id":"T15","span":{"begin":630,"end":639},"obj":"PosReg"},{"id":"T16","span":{"begin":640,"end":666},"obj":"MPA"}],"relations":[{"id":"R1","pred":"ThemeOf","subj":"T1","obj":"T2"},{"id":"R10","pred":"CauseOf","subj":"T12","obj":"T13"},{"id":"R11","pred":"ThemeOf","subj":"T14","obj":"T13"},{"id":"R12","pred":"CauseOf","subj":"T12","obj":"T15"},{"id":"R13","pred":"ThemeOf","subj":"T16","obj":"T15"},{"id":"R2","pred":"CauseOf","subj":"T2","obj":"T3"},{"id":"R3","pred":"ThemeOf","subj":"T5","obj":"T3"},{"id":"R4","pred":"ThemeOf","subj":"T4","obj":"T5"},{"id":"R5","pred":"CauseOf","subj":"T6","obj":"T7"},{"id":"R6","pred":"ThemeOf","subj":"T8","obj":"T7"},{"id":"R7","pred":"CauseOf","subj":"T6","obj":"T9"},{"id":"R8","pred":"ThemeOf","subj":"T10","obj":"T9"},{"id":"R9","pred":"ThemeOf","subj":"T11","obj":"T12"}],"attributes":[{"subj":"T1","pred":"source","obj":"name_no"},{"subj":"T2","pred":"source","obj":"name_no"},{"subj":"T3","pred":"source","obj":"name_no"},{"subj":"T5","pred":"source","obj":"name_no"},{"subj":"T4","pred":"source","obj":"name_no"},{"subj":"T6","pred":"source","obj":"name_no"},{"subj":"T7","pred":"source","obj":"name_no"},{"subj":"T8","pred":"source","obj":"name_no"},{"subj":"T9","pred":"source","obj":"name_no"},{"subj":"T10","pred":"source","obj":"name_no"},{"subj":"T11","pred":"source","obj":"name_no"},{"subj":"T12","pred":"source","obj":"name_no"},{"subj":"T13","pred":"source","obj":"name_no"},{"subj":"T14","pred":"source","obj":"name_no"},{"subj":"T15","pred":"source","obj":"name_no"},{"subj":"T16","pred":"source","obj":"name_no"}]}],"config":{"attribute
