Fig. 1From: Increased expression of prokineticin 2 and its receptor in endometrium of recurrent implantation failure patients decreased the expression of MMP9 important for decidualizationExpression of PK2, PKR1, PRL, and IGFBP1 in the endometrium of control group and RIF group. A PK2 and PKR1 levels were measured by qRT-PCR in control and RIF groups; B PRL and IGFBP1 levels were measured by qRT-PCR in two groups; C,D Western blotting and densitometric analyses of PK2, PKR1, PRL, IGFBP1 protein levels in two groups; ** P < 0.01Back to article page
