Objective:To explore relationships between CANX expression,prognosis and immune infiltration of acute myeloid leukemia(AML)patients.Methods:The TIMER database was used to compare the CANX expression among a variety of TCGA tumor and normal tissue samples.The difference of CANX expression between AML and normal samples was found by R software.The Kaplan-Meier method and Log-Rank test were used to assess the relationship between CANX expression and patient survival.The R software was used to find correlations between CANX expression,clinical characteristics,drug sensitivity,and immune infiltration in AML.Results:The differential expression of CANX in 13 tumor and normal tissue samples were statistically significant(P<0.05).The high CANX expression was associated with a favorable prognosis(P<0.05),which was validated in GSE37642.The expression of CANX was correlated with age,survival status,FAB stage,and karyotype(P<0.05).High CANX expression,low age and favorable karyotype were independent predictors of a favorable prognosis(P<0.05).CANX expression may affect the sensitivity of AML patients to multiple drugs(P<0.05).The expression of CANX was positively correlated with that of M1 macrophages and CD8 T cells.Conclusion:CANX may be used as a novel potential biomarker,and could benefit AML patients by predicting patient prognosis and providing precise treatment indications.
