In triple-negative breast cancer (TNBC), SMARCA4, a core subunit of the ATPase-dependent protein complex SWI/SNF, interacts with the lncRNA TGFB2-AS1 [37], an antisense RNA to the protein coding TGFB2 (Transforming Growth Factor Beta 2) gene. This evidence concerns the gene TGFB2 and triple-negative breast carcinoma.
