TACR1 and acute myeloid leukemia: By analyzing NK-1R gene expression in Gene Expression Profiling Interactive Analysis (http://gepia.cancer-pku.cn/), a webserver for gene expression profiling based on The Cancer Genome Atlas data (29), we found up-regulated NK-1R messenger RNA (mRNA) expression in AML patients compared with normal controls, implicating a potential pathological role of NK-1R in AML.
