Sequence of events in prostate #cancer, by @MarkARubin1
http://www.Nature.com/articles/d41586-018-06029-5 Discusses the high prevalence of AR-enhancer amplifications in recent studies

“Quigley and colleagues performed whole-genome sequencing of 101 samples of metastatic, castration-resistant prostate-cancer tissue obtained from previous studies11,12. The most frequently altered genomic site identified was the AR-enhancer region, which was amplified in 81% of samples. The high prevalence of this type of amplification is notable because enhancer amplifications identified so far for other cancer types generally arise at much lower
frequency13–16. Moreover, the high prevalence of this AR-enhancer amplification in the data presented by Viswanathan and Quigley contrasts with its occurrence in only 1 of 54 previously published whole-genome sequences of prostate-cancer samples obtained before clinical treatment had commenced17.”

“… comprehensive genomic characterization of 27 strains of the common breast cancer cell line MCF7 uncovered rapid genetic
diversification. Similar results were obtained with multiple strains of 13 additional cell lines.

Here is the STAR Methods format (Structured, Transparent, Accessible Reporting) introduced last year by Cell, marketed as a structure that “promotes transparent reporting of experimental design and
methodological details.” Details are in the links below.

“The NCI will continue to supply the NCI-60 cell lines to researchers, but will eventually refocus its drug screening on newer models. It is developing hundreds of ‘patient-derived xenografts’ (PDXs), which are created by implanting small chunks of human tumours into mice. There, the tumours grow in an environment that, although not human, better mimics their native environment”
