Figure 4From: Proto-oncogene c-erbB2 initiates rat primordial follicle growth via PKC and MAPK pathwaysEffect of c-erbB 2 siRNA on c-erbB 2 mRNA expression. (A), Expression of c-erbB 2 mRNA (322 bp) measured by RT-PCR in cultured ovaries after c-erbB 2 siRNA transfection. (B), Semiquantitative analysis of the RT-PCR results. Control is the group without transfection; Negetive control is the group transfected with negative control siRNA. Data are presented as means ± SEM (n = 3). **, P < 0.01.Back to article page
