抄録

The expression of mRNA encoding luteinizing hormone receptor (LHR) and follicle-stimulating hormone receptor (FSHR) was studied in chicken gonads from day 10 of incubation to day 14 of posthatch by Northern hybridization and expression of each mRNA was compared between sexes. LHR mRNA levels in the left ovary increased from day 12 of incubation, reached a peak two days later and remained high thereafter. In contrast, those in the testes remained extremely low until day 18 of incubation but started increasing sharply from day 20 of incubation and reached peak levels at the posthatch day 7. FSHR mRNA levels of the gonads displayed similar changes between both sexes. The changes resembled those of LHR mRNA levels of the testis during the examined period. These results suggest that the earlier expression of LHR mRNA in the ovary is involved in earlier estrogen production and the later expression of LHR mRNA in the testis is involved in androgen production at the late stage of development in the chick. The later expression of FSHR mRNA may be associated with some gonadal functions in common to both sexes.
