โœฆ Synopsis


The presence of a prostatic-like acid phosphatase is reported in human lactating milk. Its activity is associated with skim milk and it could be separated from the other acid phosphatases only after Triton X-100 treatment. By all the criteria applied, it appears to be very similar to prostatic acid phosphatase. An approximate molecular weight of 96 000 was measured for the native enzyme, which is inhibited by L-(+)tartrate and has similar electrophoretic migration. Besides, it hydrolyzes choline-o-phosphate very well and cross-reacts with an antibody anti-prostatic acid phosphatase. This prostatic-like acid phosphatase has also been detected in a human mammary carcinoma from a lactating patient.

The stimulated secretion of prostatic acid phosphatase (PAcP) has been known to be a hallmark of androgen action on human prostate epithelial cells for the last five decades. The molecular mechanism of androgen action on PAcP secretion, however, has remained mostly unknown. We investigated the molec
