We found a statistically significant positive relationship between SMARCA1 and the estimated value of cancer-associated fibroblasts infiltration for BRCA, CESC, COAD, ESCA, HNSC, HNSC-HPV-, PAAD, READ, STAD and TGCT (Fig 10A, P < 0.05) based on all the algorithms. Here, SMARCA1 is linked to cancer.
