Q: Question: Does pTEN loss in biopsy tissue predict poor clinical outcomes in prostate cancer?
Answer: PTEN loss at the time of biopsy seems to predict time to development of metastasis, prostate cancer-specific mortality and, for the first time, castration-resistant prostate cancer and response to androgen deprivation therapy after radical prostatectomy. If confirmed by larger studies, this would support the use of PTEN loss as an early marker of aggressive prostate cancer.

A: yes

Q: Question: Does inhibition of osteoclasts prevent joint ankylosis in a mouse model of spondyloarthritis?
Answer: These data suggest that bone erosion at the enthesis does not necessarily precede entheseal ankylosis. Therefore, these observations further support the concept that inflammation and new tissue formation in SpA are at least partially uncoupled events and may be different therapeutic targets.

A:
no
