Carrageenan 103-114 Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus 130-135 9824685-3 1998 Two hours after intraplantar injection of carrageenin (6 mg/150 microliter of saline), c-Fos-like immunoreactivity (FLI) was observed predominantly in the superficial and deep laminae of the dorsal horn in segments L4 and L5 of the spinal cord. Carrageenan 42-53 Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus 87-92
