Therefore, the current study specifically investigated bone cell activity in clinical bone metastases in relation to tumor cell AR activity, in order to gain novel insight into biological heterogeneities of possible importance for patient stratification into bone-targeting therapies.

Multivariate logistic regression showed that PSA (OR: 1.005; 95%CI: 1.001-1.010; P=0.016), Gleason score (OR: 4.095; 95%CI: 1.592-10.529; P=0.003), and AR expression (OR: 14.023; 95%CI: 3.531-55.6981; P=0.005) were independently associated with bone metastases.

The majority of CRPC bone metastases (80%) was defined as AR-driven based on PCA analysis and high expression of the AR, AR co-regulators (FOXA1, HOXB13), and AR-regulated genes (KLK2, KLK3, NKX3.1, STEAP2, TMPRSS2); 20% were non-AR-driven.

Sub-groups of bone metastases could be identified according to their expression levels of AKR1C3 and AR-Vs, which might be of relevance for patient response to 2(nd) line androgen-deprivation therapy.

By comparing expression profiles of primary prostate cancer biopsies, with and without bone metastasis, we discovered that the expression of activin A is increased in cases with bone metastatic propensity and correlates with increased androgen receptor (AR), PSA expression, and Gleason scores.

A relatively high frequency of the Thr868Ala mutation (originally reported for the human prostate cancer cell line androgen receptor) is particularly found in metastatic lesions (bone metastases) of prostate cancer and can be considered as a hot spot.
