title: Coincident induction of K rev-1/rap 1A, rap 1B and H-ras mRNAs in the rat spinal cord by noxious stimulation.
abstract: Two cDNA fragments, K rev-1/rap 1A and rap 1B, were amplified from total cellular RNA of the rat spinal cord by reverse transcription-polymerase chain reaction with a set of oligonucleotide primers specific for the human rap 1A cDNA. We report here using Northern blot analysis with these cDNA probes that noxious stimulation causes a marked and coincident increase in rap 1A, rap 1B and H-ras mRNAs in the rat spinal cord. This suggests that Rap 1 participates in sensory processing in spinal neurons in parallel with Ras.
