By assessing multiple discrete areas across multiple metastases, we find a high level of intra-patient homogeneity with respect to tumor phenotype. Here we use digital spatial profiling (DSP) technology to quantitate transcript and protein abundance in spatially-distinct regions of mPCs. However, the extent of inter- and intra-tumor heterogeneity is not established. Metastatic prostate cancer (mPC) comprises a spectrum of diverse phenotypes. We operate a private outpatient clinic in Smithers, British Columbia that offers physiotherapy, massage therapy, acupuncture, concussion screening, ergonomic assessments, pre-employment screening, and intra-muscular stimulation (IMS). Alpine physiotherapy was established in 2000 and is a leading provider of physical assessment and rehabilitation.

The recording format is XAVC, which was first used in. The PXW-Z100 uses Exmor R CMOS sensors capable of 4K resolution (4096 x 2160) at 60 fps or 50fps, while weighing under 3 kg even with a 4K-compatible high-performance G lens mounted. Notably, the variation in the histological patterns are highly prognostic of PC outcomes 1, and molecular assays of gene expression also associate with recurrences following prostatectomy and radiotherapy, indicating a high degree of interindividual variation in tumor behavior 7.Professional handheld camcorder records 4K using the XAVC format on to XQD solid state memory cards. As observed in most solid tumors, PCs are comprised of heterogeneous populations of neoplastic cells interacting within complex ecosystems of resident cell types such as fibroblasts and vascular endothelium, infiltrating cell types including immune cells, as well as nutrients, growth factors, collagens, and other constituents that collectively contribute to an organizational framework that supports cancer cell survival and growth 6. At the time of diagnosis, biopsies often demonstrate the presence of multiple histological Gleason patterns, and independent cancer foci harbor distinct structural genomic alterations such as those involving TMPRSS2-ERG rearrangements 1вЂ“ 5. Attachment cc: Corporate Audit and Response Management Retail Systems Software Business Process Controls Report Number FT-AR-15-008 3Localized prostate cancer (PC) is notable for substantial inter- and intratumor heterogeneity in both phenotype and molecular composition.

Collectively, these studies emphasize that PC is driven by a diverse spectrum of oncogenic aberrations and provide strong rationale for personalized/precision approaches for cancer therapy.While the application of advanced technologies such as laser-assisted microdissection, proteomics, single-cell sequencing, and spatial transcriptomics have delineated the molecular diversity of localized PCs, an understanding of the intraindividual and intratumoral diversity of metastatic PC is lacking 13вЂ“ 17. The results of TCGA for localized PC 8 and further efforts involving analyses of metastatic PC identified molecular subtypes of PC with otherwise indistinguishable histological features and nominated new therapeutic targets 9вЂ“ 12. Applying genome-scale technologies to cancer resulted in the construction of The Cancer Genome Atlas (TCGA) that provided a working taxonomy for numerous solid tumors and hematological malignancies. Insulin.The recognition that cancers originating from the same organ can harbor a spectrum of oncogenic and tumor suppressor alterations between individuals led to concerted efforts to understand the diversity and frequency of pathogenic molecular features present in common human malignancies. Particularly central (intra-abdominal) adiposity, and relative inactivity.

We apply this method to the study of formalin-fixed tumor biospecimens from multiple metastatic sites, including bone, acquired through rapid autopsy. However, the intra- and intertumor variation in these phenotypes and potential associations with tumor-microenvironment (TME) features such as immune responses has not been evaluated.In this study, we seek to investigate the inter- and intratumor variation in gene expression using an approach termed digital spatial profiling (DSP) for quantitative, high-plex analysis of mRNAs and proteins in spatially defined regions of PC metastasis 24, 25. In addition to genomic aberrations, recent studies have identified processes contributing to therapy resistance involving alterations in tumor phenotypes through transdifferentiation that may be driven by epigenetic modifications 20вЂ“ 23. Autopsy studies capable of evaluating multiple disseminated tumors within an individual patient determined that in the majority of patients, all PC metastasis share a common monoclonal origin, but subsequent therapeutic pressures promote a degree of diversity with respect to resistance mechanisms 10, 18, 19.

Reasons for exclusion include missing/100% fat ( NвЂ‰=вЂ‰14), 100% stroma ( NвЂ‰=вЂ‰1), quality control failure ( NвЂ‰=вЂ‰4), or в‰¤100 genes detected ( NвЂ‰=вЂ‰8). Of the total 168 ROIs, 141 were utilized for analysis. One 500вЂ‰ВµM region of interest (ROI) per core was selected for DSP. NвЂ‰=вЂ‰27 patients from the UW Rapid Autopsy Program were selected with two sites of metastasis per patient ( NвЂ‰=вЂ‰56).

Gene counts are displayed on the left side (green) and the geometric mean of negative probe counts is displayed on the right side (gray). C Split violin plot overlaid on scatterplot of RNA assay counts by patient ( NвЂ‰=вЂ‰3-12 ROIs for most patients). Both assays were read out by next-generation sequencing. Serial sections of the TMA were run through GeoMx RNA (top) or GeoMx protein (bottom) assays.

LOQ was defined as three times the geometric mean of the negative control antibodies.To quantitate gene expression in spatially defined tumor regions, we assembled a gene panel of utility in assessing the molecular composition of neoplastic disease that included transcripts for the functional classification of PC phenotypes and the categorization of specific cell types. F Histogram of the number of proteins above the limit of quantitation (LOQ) per ROI. Antibody counts are displayed on the left side (green) and the geometric mean of negative control antibodies (mouse and rabbits IgGs) displayed on the right side (gray). E Split violin plot overlaid on scatterplot of protein assay counts by patient ( NвЂ‰=вЂ‰3-12 ROIs for most patients). LOQ was defined as the geometric mean of the negative probesвЂ‰Г—вЂ‰geometric standard deviation of negative probes squared.

Negative probe counts were used to set a limit of quantitation (LOQ), which was defined as the geometric mean plus two standard deviations of the negative probes. Gene and negative count distributions for each patient ( NвЂ‰=вЂ‰6 ROIs for most patients) are shown in Fig. These cores were excluded from further analyses for both protein and RNA experiments.For the RNA DSP, probe counts were collapsed to gene counts by first removing outlier probes and then taking the geometric mean of remaining probes for each gene in each ROI. For the RNA DSP assay, seven additional ROIs were missing and four did not pass sequencing quality control. Manual inspection of the TMAs used for DSP determined that of 168 cores arrayed, 7 were either missing or were 100% fat and 1 was entirely stroma devoid of tumor cells. Following probe hybridization, UV cleavage, and barcode collection, gene expression was quantitated by Illumina sequencing (for protein) or by PCR amplification and Illumina sequencing (for RNA) (Fig.
