FOSL1 promotes oxaliplatin resistance in CRC by suppressing ferroptosis through the upregulation of SRSF2. Targeting FOSL1 may represent a novel therapeutic strategy to overcome oxaliplatin resistance in colorectal cancer.

SRSF2 (Serine and arginine rich splicing factor 2) • GPX4 (Glutathione Peroxidase 4) • FOSL1 (FOS Like 1) • SLC7A11 (Solute Carrier Family 7 Member 11)
We found a p53-mediated downregulation of the Solute Carrier Family 7 Member 11 (SLC7A11)/Cystine/Glutamate Transporter (xCT) expression and glutathione levels. Our results suggest that combined administration of DMF and cisplatin, by targeting the dependency of cervical cancer cells on glutathione and (re)activating p53, represents a promising anticancer therapeutic strategy.
The patient received craniospinal radiation with a boost and concurrent temozolomide. She achieved rapid and significant neurologic recovery of function with KPS increasing to 90, accompanied by radiographic improvement. This case highlights the utility of PET/MRI in biopsy planning and underscores the importance of integrated histological and molecular diagnosis for management of non-enhancing gliomas.
