ACTA1 and non-small cell lung carcinoma: Our cohort study detected a strong positive correlation between the abundance of RUNX1+ TAMs and MMTs in NSCLC (P < 0.0001; r = 0.4393) but absent between the abundance of RUNX1 and α‐SMA alone (Figure 2C), and high level of RUNX1+ TAMs was associated with the mortality of NSCLC patients (Figure 2D).
