FADS1 and neoplasm: To further elucidate the effect of LINC01569/miR-193a-5p/FADS1 in macrophages on hypopharyngeal carcinoma cell growth, a co-culture of macrophages and hypopharyngeal carcinoma cells (transfected with LINC01569 siRNA or miR-193a-5p inhibitor) was used to detect tumor cell proliferation and apoptosis combining with the Transwell apparatus (Fig. 8A).
