Notably, PTSL and six other p53 transactivated lncRNAs (TP53TG1, GUARDIN, PSLR-1, PSLR-2, AC096677.2, and LINC00475) potentially suppress proliferation in >5 cancer types by modulating ≥5 proliferation-associated Hallmark gene sets (ref. 61; Fig. 4B). This evidence concerns the gene TP53TG1 and cancer.
