Placental Lactogen Is Expressed but Is Not Translated into Protein in Breast Cancer
Figure 7
Expression of CSH mRNA in some primary breast carcinomas but undetectable hPL protein.
(A) Comparison of CSH expression by real-time PCR in eight primary tumors (T1–T8) and three normal breast tissue samples (N1–N3). Data are presented as fold over ZR75 cells used for reference. (B) None of the above tissues show hPL protein, as determined in western blotting using mAb-6, which detected rhPL, placental hPL, and hPL in overexpressing MCF7 cells (MCF7-PL).
