Fig 5. Expression of tilapia CREBs during: (A) natural ovarian cycle and (B) hCG induced -oocyte maturation as determined by RT-PCR and Northern Blot respectively. A plasmid DNA with CREB partial cDNA was used as positive control (PC) and PCR reaction without RT was used as negative control (NC) (Ma, Marker). (C) Densitometric analysis of CREB2 and CREB3 (mean ±SEM of two independent experiments).
