Figure 4. Expression levels of PCSKs in mechanically isolated mouse follicles.

The mRNA levels of furin (A), PCSK5 (B), PCSK6 (C) and PCSK7 (D) subunits were measured using real-time RT-PCR and are shown as a ratio over the 50–100 micron follicle levels. The bars labeled with different letters indicate statistically significant differences, as determined by Tukey's multiple comparison test (p<0.05).
