Resumen:
A B S T R A C TIn the present study, we determined the hepatopancratic shbg transcript abundance and ovarian immunoreactiveShbg (ir-Shbg) localization in pejerrey females at different gonadal stages during an annual ovarian cycle. In thehepatopancreas, shbg expression remains was constant in pre-vitellogenic stages, decreased at final vitellogenesisto increase again in final maturation and atretic stages to previous levels at post-vitellogenic stages. Related tothis, also we found a negative significant relation between sex steroid and shbg expression. On the other hand, inthe ovary we found ir-Shbg inside of cortical alveoli, from previtellogenic stages to final maturation. This localization of Shbg in a teleost fish ovary suggests a new role for Shbg in oocytes, that may also extend the oocytefertilization/development process.
