TBXT and lung cancer: We chose CXCL2, T-box transcription factor T (TBXT), cadherin 1 (CDH1), and catenin beta 1 (CTNNB1), based on three criteria, (1) significant difference of fold-change values at single-cell level, (2) potentiality as a molecular biomarker in lung cancers, and (3) association with EMT.
