Metastatic Castrate-Resistant Prostate Cancer Study (MCRPCS)

ABSTRACT:

We examined genetic resistance to second generation androgen targeting therapies (abiraterone acetate or enzalutamide) by analyzing whole exome sequencing of patient-matched pre-treatment and post-resistance tumors from a series of castrate-resistant prostate cancer (CRPC) patients. Abiraterone resistant tumors harbored alterations in AR and MYC, whereas patients treated with enzalutamide had acquired alterations in the cell cycle pathway. We experimentally confirmed expression of cell-cycle kinases sufficed to drive enzalutamide resistance, which was mitigated through CDK4/6 blockade. These observations link genetic resistance to specific therapeutic agents to inform strategies in genomically selected advanced CRPC.

Hes6 expression is controlled by c-Myc and the AR to promote E2F1 activity and poor outcome in castrate-resistant prostate cancer (cMyc ChIP-seq)

Project description:Hes6 is a transcription co-factor that is associated with stem cell characteristics in neural tissue, but its role in cancer remains uncertain. Here we show that Hes6 is controlled by c-Myc and the AR and can drive castration resistance in xenografts of the androgen-dependent LNCaP prostate cancer cell line model. Hes6 activates a cell cycle enhancing transcriptional network that maintains tumour growth in the absence of circulating androgen but with maintained nuclear AR. We demonstrate interaction between E2F1, the AR and Hes6 and show the co-dependency of these factors in the castration-resistant setting. In the clinical setting, we have discovered a Hes6-associated signature that predicts poor outcome in prostate cancer, which could be pharmacologically targeted. Myc ChIPseq on LNCaP cells.

Regulation of the glucocorticoid receptor via a BET-dependent enhancer drives antiandrogen resistance in prostate cancer

Project description:In prostate cancer, resistance to the antiandrogen enzalutamide (Enz) can occur through bypass of androgen receptor (AR) blockade by the glucocorticoid receptor (GR). In contrast to fixed genomic alterations, here we show that GR-mediated antiandrogen resistance is adaptive and reversible due to regulation of GR expression by a tissue-specific enhancer. GR expression is silenced in prostate cancer by a combination of AR binding and EZH2-mediated repression at the GR locus, but is restored in advanced prostate cancers upon reversion of both repressive signals. Remarkably, BET bromodomain inhibition resensitizes drug-resistant tumors to Enz by selectively impairing the GR signaling axis via this enhancer. In addition to revealing an underlying molecular mechanism of GR-driven drug resistance, these data suggest that inhibitors of broadly active chromatin-readers could have utility in nuanced clinical contexts of acquired drug resistance with a more favorable therapeutic index.

Integrative Clinical Sequencing Analysis of Metastatic Castration Resistant Prostate Cancer Reveals a High Frequency of Clinical Actionability

Project description:<p>Most prostate cancer deaths are caused by metastatic, castration resistant disease (mCRPC). To develop a precision medicine framework for mCRPC, we established a multi-institutional, international clinical sequencing infrastructure to enroll and carry out prospective whole exome and transcriptome sequencing of tumors from a cohort of mCRPC patients. We obtained high quality DNA and RNA sequence data from 150 bone or soft tissue biopsies. Central pathology revealed high-grade adenocarcinoma with only four cases (3.6%) showing neuroendocrine differentiation. Aberrations of AR, ETS genes, TP53 and PTEN were frequent (40-60% of cases), with TP53 and AR alterations being the most enriched in mCRPC compared to primary prostate cancer. We identified novel genomic alterations in PIK3CA/B (fusions and mutations); R-spondin, BRAF and RAF1 (fusions); APC (inactivating mutations); delta-catenin (missense mutations); and ZBTB16/PLZF (homozygous deletions). Aberrations of BRCA2, BRCA1 and ATM were observed at substantially higher frequencies (19.3% overall) than seen in primary prostate cancers, with 56% of these being exclusively somatic. Putative driver gene alterations were identified in nearly all patients, and over half also harbored driver gene fusions, homozygous deletions and/or amplifications. Moreover, 89% of patients harbored a clinically actionable aberration including 62.7% with aberrations in AR, 65% in other cancer-related genes, and 8% with actionable pathogenic germline alterations. Overall, integrative clinical sequencing analysis can be safely and efficiently performed in mCRPC, yields findings that may be actionable for enrolling patients in clinical trials of targeted therapies, and may inform the basis of individual clinical responses.</p>

Molecular patterns of resistance to immune checkpoint blockade in melanoma [scRNA-Seq]

Project description:Immune checkpoint blockade (ICB) has improved outcome for patients with metastatic melanoma but not all benefit from treatment. Several immune- and tumor intrinsic features are associated with clinical response at baseline. However, we need to further understand the molecular changes occurring during development of ICB resistance. Here, we collected biopsies from a cohort of 44 melanoma patients after progression to anti-CTLA4 or anti-PD1 monotherapy. Genetic alterations of antigen presentation and interferon gamma signaling pathways were observed in approximately 25% of ICB resistant cases. Anti-CTLA4 resistant lesions had a sustained immune response, including immune-regulatory features, as suggested by multiplex spatial and TCR clonality analyses. One anti-PD1 resistant lesion harbored a distinct immune cell niche, however, anti-PD1 resistant tumors were generally immune poor with non-expanded TCR clones. Such immune poor microenvironments were associated with melanoma cells having a de-differentiated phenotype lacking expression of MHC-I molecules. In addition, anti-PD1 resistant tumors had reduced fractions of PD1+ CD8+ T cells as compared to ICB naïve metastases. Collectively, these data show the complexity of ICB resistance and highlight differences between anti-CTLA4 and anti-PD1 resistance that may underlie differential clinical outcomes of therapy sequence and combination.

Hes6 drives a network with therapeutic potential in castrate-resistant prostate cancer

Project description:Castrate-resistant prostate cancer (CRPC) is poorly characterized and heterogeneous and while the androgen receptor (AR) is of singular importance in early prostate cancer, other factors such as c-Myc and the E2F family also play a role in later stage disease. Hes6 is a transcription co-factor that has been associated with neurogenesis during gastrulation, a neuroendocrine phenotype in the prostate and metastasis in breast cancer but its role in prostate cancer remains uncertain. Here we show that Hes6 is controlled by c-Myc and AR and drives castration resistance in prostate cancer. Hes6 activates a cell-cycle enhancing transcriptional network that maintains tumour growth and nuclear AR localization in castrate conditions. We show aphysical interaction between E2F1 and both Hes6 and AR, and suggest a co-dependency of these transcription factors in castration-resistance. In the clinical setting, we have uncovered a Hes6-associated signature that predicts poor outcome in prostate cancer, which can be pharmacologically targeted. We have therefore shown for the first time the critical role of Hes6 in the development of CRPC and identified its potential in patient specific therapeutic strategies.

Temporal evolution of cellular heterogeneity during the progression to advanced, AR-negative prostate cancer [scRNA-seq]

Project description:Despite advances in the development of highly effective androgen receptor (AR)-directed therapies for the treatment of men with advanced prostate cancer, acquired resistance ultimately ensues. A significant subset of patients with resistant disease develop AR-null, androgen-indifferent tumors that lose their luminal identify and display neuroendocrine features (neuroendocrine prostate cancer (NEPC)). Utilizing a genetically engineered mouse model, we have characterized the synergy between N-Myc overexpression and RB1 loss-of-function which results in the formation of AR-negative, poorly differentiated tumors with high metastatic potential. Single-cell-based approaches revealed striking changes to the transcriptome and chromatin accessibility during the transition to NEPC. Global DNA methylation and the N-Myc cistrome are redirected following RB1 loss. Altogether, our data provide new insight into the progression to NEPC.
