Resumen
In the present study, we determined the hepatopancratic shbg transcript abundance and ovarian immunoreactive Shbg (ir-Shbg) localization in pejerrey females at different gonadal stages during an annual ovarian cycle. In the hepatopancreas, shbg expression remains was constant in pre-vitellogenic stages, decreased at final vitellogenesis to increase again in final maturation and atretic stages to previous levels at post-vitellogenic stages. Related to this, also we found a negative significant relation between sex steroid and shbg expression. On the other hand, in the 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 oocyte fertilization/development process.
