Fig. 1. Effects of 2-hydroxyestradiol-17ß (2-OHE2, 5 µmol
l1) on germinal vesicle breakdown (GVBD, line curves) and
cAMP level (bars) in Heteropneustes fossilis. Values are means
± s.e.m. (N=3 for GVBD assay; N=5 for cAMP assay).
Data were analyzed by one-way ANOVA (P<0.001) and
NewmanKeuls' test (P<0.05). Asterisks indicate significant
difference from the respective vehicle control groups
(P<0.05).
