FOSL1 and head and neck squamous cell carcinoma: Similarly, in head and neck squamous cell carcinoma, the long noncoding RNA (lncRNA) CYTOR stabilizes FOS Like 1 (FOSL1)-dependent transcriptional condensates at SEs (FOSL1 is an AP-1 TF subunit), promoting SE-driven expression of metastasis-related genes (e.g., MMP9) (Wang et al., 2024) (Figure 1A).
