Abstract
Adrenocortical carcinoma (ACC) is a rare but highly aggressive cancer with limited treatment options and poor survival for patients with advanced disease. An improved understanding of the transcriptional programs engaged in ACC will help direct rational, targeted therapies. Whereas activating mutations in Wnt/β-catenin signaling are frequently observed, the β-catenin-dependent transcriptional targets that promote tumor progression are poorly understood. To address this question, we analyzed ACC transcriptome data and identified a novel Wnt/β-catenin-associated signature in ACC enriched for the extracellular matrix (ECM) and predictive of poor survival. This suggested an oncogenic role for Wnt/β-catenin in regulating the ACC microenvironment. We further investigated the minor fibrillar collagen, collagen XI alpha 1 (COL11A1), and found that COL11A1 expression originates specifically from cancer cells and is strongly correlated with both Wnt/β-catenin activation and poor patient survival. Inhibition of constitutively active Wnt/β-catenin signaling in the human ACC cell line, NCI-H295R, significantly reduced the expression of COL11A1 and other ECM components and decreased cancer cell viability. To investigate the preclinical potential of Wnt/β-catenin inhibition in the adrenal microenvironment, we developed a minimally invasive orthotopic xenograft model of ACC and demonstrated that treatment with the newly developed Wnt/β-catenin:TBL1 inhibitor Tegavivint significantly reduced tumor growth. Together, our data support that the inhibition of aberrantly active Wnt/β-catenin disrupts transcriptional reprogramming of the microenvironment and reduces ACC growth and survival. Furthermore, this β-catenin-dependent oncogenic program can be therapeutically targeted with a newly developed Wnt/β-catenin inhibitor. These results show promise for the further clinical development of Wnt/β-catenin inhibitors in ACC and unveil a novel Wnt/β-catenin-regulated transcriptome.

Abstract
Adrenocortical carcinoma (ACC) is a rare cancer in which tissue-specific differentiation is paradoxically associated with dismal outcomes. The differentiated ACC subtype CIMP-high is prevalent, incurable, and routinely fatal. CIMP-high ACC possess abnormal DNA methylation and frequent β-catenin-activating mutations. Here, we demonstrated that ACC differentiation is maintained by a balance between nuclear, tissue-specific β-catenin-containing complexes, and the epigenome. On chromatin, β-catenin bound master adrenal transcription factor SF1 and hijacked the adrenocortical super-enhancer landscape to maintain differentiation in CIMP-high ACC; off chromatin, β-catenin bound histone methyltransferase EZH2. SF1/β-catenin and EZH2/β-catenin complexes present in normal adrenals persisted through all phases of ACC evolution. Pharmacologic EZH2 inhibition in CIMP-high ACC expelled SF1/β-catenin from chromatin and favored EZH2/β-catenin assembly, erasing differentiation and restraining cancer growth in vitro and in vivo. These studies illustrate how tissue-specific programs shape oncogene selection, surreptitiously encoding targetable therapeutic vulnerabilities. SIGNIFICANCE Oncogenic β-catenin can use tissue-specific partners to regulate cellular differentiation programs that can be reversed by epigenetic therapies, identifying epigenetic control of differentiation as a viable target for β-catenin-driven cancers.

Abstract
Abstract
Adrenocortical carcinoma (ACC) is a rare cancer of the adrenal cortex without curative medical therapies. CIMP-high is an aggressive ACC molecular subtype defined by global CpG island hypermethylation with paradoxical activation of adrenal differentiation (driven by master transcription factor SF1) and stemness (driven by β-catenin). We show DNA hypermethylation redistributes histone methyltransferase EZH2 and its mark, H3K27me3. EZH2 inhibition remains lethal to CIMP-high ACC cells, erasing transcriptional programs without altering DNA methylation. We reconcile this phenomenon by discovery of two nuclear complexes, SF1/β-catenin and EZH2/β-catenin, present in physiology and persistent through advanced ACC. We find SF1/β-catenin is a chromatin-bound complex that controls the ACC super-enhancer landscape, while EZH2/β-catenin is restricted to off-chromatin pools. EZH2 inhibition purges SF1/β-catenin from chromatin, sparing EZH2/β-catenin, inducing dedifferentiation and restraining ACC growth in vitro and in vivo. Our studies illustrate how cell-of-origin programs dictate cancer evolution, exposing differentiation as an therapeutic vulnerability.

Abstract
OBJECTIVE The authors searched for genetic and transcriptional signatures associated with tumor progression and recurrence in their cohort of patients with meningiomas, combining the analysis of targeted exome, NF2-LOH, transcriptome, and protein expressions. METHODS The authors included 91 patients who underwent resection of intracranial meningioma at their institution between June 2000 and November 2007. The search of somatic mutations was performed by Next Generation Sequencing through a customized panel and multiplex ligation-dependent probe amplification for NF2 loss of heterozygosity. The transcriptomic profile was analyzed by QuantSeq 3' mRNA-Seq. The differentially expressed genes of interest were validated at the protein level analysis by immunohistochemistry. RESULTS The transcriptomic analysis identified an upregulated set of genes related to metabolism and cell cycle and downregulated genes related to immune response and extracellular matrix remodeling in grade 2 (atypical) meningiomas, with a significant difference in recurrent compared with nonrecurrent cases. EZH2 nuclear positivity associated with grade 2, particularly with recurrent tumors and EZH2 gene expression level, correlated positively with the expression of genes related to cell cycle and negatively to genes related to immune response and regulation of cell motility. CONCLUSIONS The authors identified modules of dysregulated genes in grade 2 meningiomas related to the activation of oxidative metabolism, cell division, cell motility due to extracellular remodeling, and immune evasion that were predictive of survival and exhibited significant correlations with EZH2 expression.

Abstract
The adrenal glands are paired endocrine organs that produce steroid hormones and catecholamines required for life. Adrenocortical carcinoma (ACC) is a rare and often fatal cancer of the peripheral domain of the gland, the adrenal cortex. Recent research in adrenal development, homeostasis, and disease have refined our understanding of the cellular and molecular programs controlling cortical growth and renewal, uncovering crucial clues into how physiologic programs are hijacked in early and late stages of malignant neoplasia. Alongside these studies, genome-wide approaches to examine adrenocortical tumors have transformed our understanding of ACC biology, and revealed that ACC is composed of distinct molecular subtypes associated with favorable, intermediate, and dismal clinical outcomes. The homogeneous transcriptional and epigenetic programs prevailing in each ACC subtype suggest likely susceptibility to any of a plethora of existing and novel targeted agents, with the caveat that therapeutic response may ultimately be limited by cancer cell plasticity. Despite enormous biomedical research advances in the last decade, the only potentially curative therapy for ACC to date is primary surgical resection, and up to 75% of patients will develop metastatic disease refractory to standard-of-care adjuvant mitotane and cytotoxic chemotherapy. A comprehensive, integrated, and current bench-to-bedside understanding of our field's investigations into adrenocortical physiology and neoplasia is crucial to developing novel clinical tools and approaches to equip the one-in-a-million patient fighting this devastating disease.

Abstract
Abstract
Adrenocortical carcinoma (ACC) is a rare, aggressive cancer. Up to 75% of patients develop incurable metastatic disease, highlighting an urgent need for novel medical therapies. We recently identified a rapidly progressive ACC subtype characterized by CpG island hypermethylation (CIMP-high), sustained Wnt/β-catenin signaling, steroidogenic differentiation, and cell cycle activation. CIMP-high status alone accounts for 40% of ACC, but predicts 70% of recurrences and >50% of deaths. Intriguingly, hypermethylated CpG islands in CIMP-high ACC are unmethylated in fetal and adult adrenal cortex, suggesting DNA methylation is supported by cancer-specific mechanisms. We therefore sought to investigate how aberrant epigenetic programming contributes to ACC biology. In embryonic stem cells, the Polycomb repressive complex 2 (PRC2) represses differentiation programs through EZH2-mediated histone H3 lysine 27 trimethylation (H3K27me3) deposition in promoter CpG islands free of DNA methylation. Gain or loss of EZH2/PRC2 function prevails in a variety of human cancers, enabling proliferation in a tissue-specific manner. Here, we identify that CIMP-high ACC exhibit high expression of EZH2/H3K27me3, but paradoxically bear DNA hypermethylation in annotated PRC2 target regions. To determine if DNA methylation of PRC2 targets disrupts or is controlled by EZH2, we characterized EZH2’s role in CIMP-high ACC cell line NCI-H295R at baseline and in response to EZH2 inhibition (EZH2i). EZH2-directed IP-MS revealed EZH2 interacts with PRC2 members and DNA methylation-sensitive accessory proteins, but no DNA methyltransferase machinery. ChIP-seq revealed EZH2 and H3K27me3 colocalize in repressive domains genome-wide, but DNA methylation and H3K27me3 are mutually exclusive. EZH2i induced H3K27 demethylation and loss of viability, but with no effect on CIMP-high DNA methylation. These data suggest PRC2 target DNA methylation in CIMP-high ACC is maintained independently of EZH2, enabling EZH2/PRC2 to coordinate alternative programs required for cell survival. We then measured the consequences of EZH2i on the NCI-H295R transcriptome (RNA-seq), EZH2/H3K27me3 deposition genome-wide (ChIP-seq), and chromatin accessibility landscape (ATAC-seq). EZH2i led to global downregulation of cell cycle, Wnt/β-catenin transcriptional programming, and steroidogenic differentiation, partially explained by EZH2i-induced offloading of EZH2 from H3K27me3 domains to accessible promoters genome-wide. Taken together, our studies illustrate how aberrant CpG island hypermethylation in CIMP-high ACC participates in a targetable repressive epigenetic cascade that reinforces oncogenic adrenocortical transcriptional programs. Ultimately, we hope to illuminate novel strategies for tissue-specific disruption of the aberrant epigenetic wiring that defines CIMP-high ACC.

Abstract
OBJECTIVES High-throughput sequencing of genomes, exomes, and disease-focused gene panels is becoming increasingly common for molecular diagnostics. However, identifying a single clinically relevant pathogenic variant among thousands of genetic polymorphisms is a challenging task. Publicly available genomic databases are useful resources to filter out common genetic variants present in the population and enable the identification of each disease-causing variant. Based on our experience applying these technologies at Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP), São Paulo, Brazil, we recognized that the Brazilian population is not adequately represented in widely available genomic databases. METHODS Here, we took advantage of our 5-year experience as a high-throughput sequencing core facility focused on individuals with putative genetic disorders to build a genomic database that may serve as a more accurate reference for our patient population: SELAdb. RESULTS/CONCLUSIONS Currently, our database comprises a final cohort of 523 unrelated individuals, including patients or family members managed by different clinics of HCFMUSP. We compared SELAdb with other publicly available genomic databases and demonstrated that this population is very heterogeneous, largely resembling Latin American individuals of mixed origin, rather than individuals of pure European ancestry. Interestingly, exclusively through SELAdb, we identified a spectrum of known and potentially novel pathogenic variants in genes associated with highly penetrant Mendelian disorders, illustrating that pathogenic variants circulating in the Brazilian population that is treated in our clinics are underrepresented in other population databases. SELAdb is freely available for public consultation at: http://intranet.fm.usp.br/sela.

Targeted Assessment of G0S2 Methylation Identifies a Rapidly Recurrent, Routinely Fatal Molecular Subtype of Adrenocortical Carcinoma. Clin Cancer Res 2019; 25:3276-3288.

Abstract
PURPOSE Adrenocortical carcinoma (ACC) is a rare, aggressive malignancy with few therapies; however, patients with locoregional disease have variable outcomes. The Cancer Genome Atlas project on ACC (ACC-TCGA) identified that cancers of patients with homogeneously rapidly recurrent or fatal disease bear a unique CpG island hypermethylation phenotype, "CIMP-high." We sought to identify a biomarker that faithfully captures this subgroup.Experimental Design: We analyzed ACC-TCGA data to characterize differentially regulated biological processes, and identify a biomarker that is methylated and silenced exclusively in CIMP-high ACC. In an independent cohort of 114 adrenocortical tumors (80 treatment-naive primary ACC, 22 adrenocortical adenomas, and 12 non-naive/nonprimary ACC), we evaluated biomarker methylation by a restriction digest/qPCR-based approach, validated by targeted bisulfite sequencing. We evaluated expression of this biomarker and additional prognostic markers by qPCR. RESULTS We show that CIMP-high ACC is characterized by upregulation of cell cycle and DNA damage response programs, and identify that hypermethylation and silencing of G0S2 distinguishes this subgroup. We confirmed G0S2 hypermethylation and silencing is exclusive to 40% of ACC, and independently predicts shorter disease-free and overall survival (median 14 and 17 months, respectively). Finally, G0S2 methylation combined with validated molecular markers (BUB1B-PINK1) stratifies ACC into three groups, with uniformly favorable, intermediate, and uniformly dismal outcomes. CONCLUSIONS G0S2 hypermethylation is a hallmark of rapidly recurrent or fatal ACC, amenable to targeted assessment using routine molecular diagnostics. Assessing G0S2 methylation is straightforward, feasible for clinical decision-making, and will enable the direction of efficacious adjuvant therapies for patients with aggressive ACC.

Abstract
Adrenocortical carcinoma (ACC) is a rare and often fatal cancer, affecting ~1 person per million per year worldwide. Approximately 75% of patients with ACC eventually develop metastases and progress on the few available standard-of-care medical therapies, highlighting an incredible need for an improved understanding of the molecular biology of this disease. Although it has long been known that ACC is characterized by certain histological and genetic features (e.g., high mitotic activity, chromosomal instability, and overexpression of IGF2), only in the last two decades of genomics has the molecular landscape of ACC been more thoroughly characterized. In this review, we describe the findings of historical genetics and recent genomics studies on ACC and discuss how underlying concepts emerging from these studies contribute to the current model of critical pathways for adrenocortical carcinogenesis. Integrative synthesis across these studies reveals that ACC consists of three distinct molecular subtypes with divergent clinical outcomes and implicates differential regulation of Wnt signaling, cell cycle, DNA methylation, immune biology, and steroidogenesis in ACC biology. These cellular programs are pharmacologically targetable and may enable the development of therapeutic strategies to improve outcomes for patients facing this devastating disease.

Abstract
Actinomyces odontolyticus has been reported as an opportunistic pathogen causing systemic infections. A case of empyema thoracis due to this organism in a 68-year-old male is reported here. The patient did not have any underlying disease or immunosuppression. The organism was isolated from his oral flora also. Eight cases of thoracopulmonary infections due to A. odontolyticus have been reported from the western countries, but none from India.

Abstract
We studied the effect of staurosporine (SSP), a broad-spectrum protein kinase inhibitor, on the levels of protein kinase C (PKC) activity and proliferation in two murine neuroblastoma cell lines, Neuro2a and its clone NB41A3. The PKC activity was examined in whole cell lysate, cytosolic and particulate fractions. A differential response to SSP treatment in the enzyme activity in whole cell lysate and particulate fractions was demonstrated in the two cell lines. The data on proliferation indicated that Neuro2a cells were more sensitive to the SSP treatment with significant inhibition in DNA synthesis in a time course study. Our findings suggest that the data on basal levels of PKC activity in tumors will be of significance in studies using PKC inhibitors as an approach for therapeutic intervention.

Abstract
This paper is concerned with the dielectrophoretic study of human erythrocytes under cylindrical field geometry. The influence of physical variables such as the frequency and voltage of the applied electric field, conductivity of the medium in which the cells are suspended, cell concentration and exposure time of the cell to the non-uniform electric field on dielectrophoretic collection rate (DCR) is determined in a systematic manner. It is interesting to note from the DCR spectrum of human erythrocytes that the DCR is minimum at one frequency, maximum at another and there is practically no yield over a certain frequency range. This may be attributed to the variation of complex dielectric constant of the particle and medium over that frequency range. From the DCR spectrum of different groups, it is clear that DCR behaviour is different in the frequency range from 0.3-1.5 MHz, under similar conditions of temperature, conductivity and concentration of erythrocyte suspension and strength of applied AC field. The response of DCR with voltage of the applied field, concentration of cell suspension and square root of elapsed time of the cells confirms the theory of dielectrophoresis.
