Effect of DSM (an inhibitor of Alk2, 3, and 6) on DHT-stimulated follicle
growth in vitro for 72 hours. (a)
TGFβ receptor inhibition by DSM. (b) Isolated
follicle growth in the presence and absence of DHT and/or DSM. Relative area
of follicles in different treatments was compared at each time point using
one-way ANOVA with a Tukey’s multiple comparisons test.
*P < 0.05,
**P < 0.01,
***P < 0.001,
****P < 00001. Values
are mean and 95% confidence interval. Numbers in parentheses are numbers of
follicles. (c–f) Effect of DHT alone, DSM alone, and DHT in
combination with DSM on gene expression following 72 hours of culture. Data
have been log2 transformed, and DHT, DSM, or DHT plus DSM
treatment was compared with control samples (0) using an unpaired
t test. Fold change is indicated in right-hand y axis.
Asterisks by error bars indicate significant difference in expression from
control, and differences between treatments are indicated by asterisks on
horizontal lines. *P < 0.05,
**P < 0.01,
***P < 0.001,
****P < 00001. Values
are mean and SEM. (c) TGFβ ligands. (d) Hormone
receptors. (e) TGFβ receptors. (f) Steroidogenic
enzymes.
