A) The mean values of the ΔC _T for women in the follicular and luteal phase in syndecan-1, syndecan-4 and decorin. 18 S was used as an endogenous control and was used for normalization of the mRNA levels for the gene of interest. The endogenous control was subtracted from respective gene giving the ΔC_T as a reflection of the relative mRNA. Since a higher ΔC_T corresponds to a lower mRNA expression the ΔC_T values are presented inverted as 10/ΔC_T. B) The mRNA expression of the proteoglycans syndecan-1, syndecan-4 and decorin in human breast tissue from 20 women, including 14 parous women. The value from the follicular phase was used as control, using the ΔΔC_T method.
