| Research Abstract |
The concentration of estrogen in the prostate tissue was very little, that it was difficult to determine it even with a newly developed ultra-sensitive analytical method utilizing liquid chromatography-tandem mass spectrometry (LC-MS/MS). Steroid hormones including active androgens and androgen-synthetic enzyme activity were demonstrated in human adipose tissue. These results suggest that adipose tissue may be another source of androgen synthesis in prostate cancer and may be related to the development of CRPC by stimulating androgen receptor-bearing cancer cells, which become hypersensitive to its ligand.
