Sarcosine has no apparent effect on the expression of the androgen receptor (AR) in LNCaP cells. (a) Relative AR mRNA levels in LNCaP cells after 24 and 48 h of sarcosine treatment. Black and grey bars represent control cells and treated cells, respectively. Mean values of at least three independent experiments are shown; error bars show SD; (b) Western blot analysis of whole cell extracts from LNCaP cells exposed to sarcosine for 24 and 48 h
