The expression of apoptosis-related genes mRNAs was examined in the dorsal skin of hypotrichotic WBN/ILA-Ht rats topically applied with T-2 toxin (10 microl of 0.5 microg/microl solution). The total mRNA was obtained from skin biopsy samples from each rat at 3, 6, 12 and 24 hours after T-2 toxin treatment (HAT), and RT-PCR was carried out with pairs of oligonucleotide primers corresponding to the cDNA sequences of rat p53, bcl-2, c-ki-ras, c-fos and c-jun oncogenes. The expression of c-fos mRNA markedly increased at 3 HAT, peaked at 6 HAT, and greatly decreased at 12 HAT. However it maintained a higher level, compared with the control level, even at 24 HAT. Although not prominent, the expression of c-jun mRNA also showed significant elevation from 3 to 12 HAT. On the other hand, there were no changes in the expression of p53, bcl-2 and c-ki-ras mRNAs throughout the observation period. Judging from the present results and our previous report that epidermal cells developed apoptosis at 12 HAT (Histol Histopathol 1999; 14: 337-342), the induction of c-fos and perhaps of c-jun mRNAs may be associated with T-2 toxin-induced epidermal cell apoptosis.
