This interesting image illustrates a case of biopsy-proven pulmonary anthracosilicosis, a mixed dust pneumoconiosis, associated with Ga-PSMA-ligand uptake. Prostate-specific membrane antigen (PSMA) is an emerging imaging biomarker, with clinical application in evaluation of prostate cancer using Ga-PSMA-ligand PET/CT. Contrary to its name, PSMA is expressed in a number of other normal tissues and pathological states. Prostate-specific membrane antigen expression has been linked to tumor angiogenesis in various other epithelial neoplasms, as well as neovasculature associated with tissue regeneration and repair...

A 76-year-old man with biochemical relapse of prostate cancer underwent Ga-prostate-specific membrane antigen PET/CT. Besides a local lymph node metastasis, a nodular structure inside the left orbit caudal to the optic nerve showed increased uptake. A metastasis in this location is unlikely. The subsequently performed MRI showed the structure being T1 hypointense, T2 indifferent, and strongly gadolinium contrast agent enhancing. Histopathologic examination after surgical removal identified the tumor as hemangiopericytoma, which rarely occurs in the orbit...

Purpose Increasing evidence indicates that statin use may reduce mortality from prostate cancer. In this work, we examined whether postdiagnosis statin use was associated with reduced cancer-specific mortality or all-cause mortality among patients with prostate cancer in Denmark. Material and Methods From nationwide Danish registries, we identified all patients with incident prostate adenocarcinoma from 1998 to 2011 and retrieved data on tumor and patient characteristics, drug use, and primary treatment. We defined postdiagnosis use (two or more prescriptions) of statins as a time-varying covariate with 1-year lag...

The bromodomain and extraterminal (BET) family of proteins comprises four members-BRD2, BRD3, BRD4 and the testis-specific isoform BRDT-that largely function as transcriptional coactivators and play critical roles in various cellular processes, including the cell cycle, apoptosis, migration and invasion. BET proteins enhance the oncogenic functions of major cancer drivers by elevating the expression of these drivers, such as c-Myc in leukemia, or by promoting the transcriptional activities of oncogenic factors, such as AR and ERG in prostate cancer...

Kinase gene fusions are important drivers of oncogenic transformation and can be inhibited with targeted therapies. Clinical grade diagnostics using RNA sequencing to detect gene rearrangements in solid tumors are limited, and the few that are available require prior knowledge of fusion break points. To address this, we have analytically validated a targeted RNA sequencing assay (OSU-SpARKFuse) for fusion detection that interrogates complete transcripts from 93 kinase and transcription factor genes. From a total of 74 positive and 36 negative control samples, OSU-SpARKFuse had 93...

The technique of whole genome amplification is advancing rapidly and generating attention on detecting genomic lesions in individual cancer cells. Also, single-cell genome could label the uniqueness of each cell, its individual mutations and structural variations especially in cancer studies. In this Review, we provide the insight into the current state of single-cell genome in urological tumor mainly including kidney cancer, bladder cancer and prostate cancer. We put more forward on the new progress of the technique used by single-cell genomes and different results of the genes transform on random tumor tissue from single cell isolated on account of tumor heterogeneity...

We investigated the potential of combining the hypoglycemic drug metformin (MET) and the anti-epileptic drug valproic acid (VPA), which act via different biochemical pathways, to provide enhanced anti-tumor responses in prostate cancer. Prostate cancer cell lines (LNCaP and PC-3), normal prostate epithelial cells (PrEC), and patient-derived prostate tumor explants were treated with MET and/or VPA. Proliferation and apoptosis were assessed. The role of p53 in response to MET+VPA was assessed in cell lines using RNA interference in LNCaP (p53(+)) and ectopic expression of p53 in PC-3 (p53(-))...

Implementing targeted drug therapy in radio-oncologic treatment regimens has greatly improved the outcome of cancer patients. However, the efficacy of molecular targeted drugs such as inhibitory antibodies or small molecule inhibitors essentially depends on target expression and activity, which both can change during the course of treatment. Radiotherapy has previously been shown to activate pro-survival pathways which can help tumor cells to adapt and thereby survive treatment. Therefore, we aimed to identify changes in signaling induced by radiation and evaluate the potential of targeting these changes with small molecules to increase the therapeutic efficacy on cancer cell survival...

Familial risks of breast cancer (BC) are well established but whether BC clusters with other, i.e. discordant, cancers is less certain but of interest for the identification of common genetic and possible environmental factors contributing to a general cancer susceptibility. We apply a novel approach to search for familial associations of BC with other (discordant) cancers based on the Swedish Family-Cancer Database. Relative risks (RRs) were calculated for BC in families with increasing numbers of patients with discordant cancer X, and conversely, familial RRs for cancer X in families with increasing numbers of BC patients...

Phosphatases and cancer have been related for many years now, as these enzymes regulate key cellular functions, including cell survival, migration, differentiation and proliferation. Dysfunctions or mutations affecting these enzymes have been demonstrated to be key factors for oncogenesis. The aim of this review is to shed light on the role of four different phosphatases (PTEN, PP2A, CDC25 and DUSP1) in five different solid tumors (breast cancer, lung cancer, pancreatic cancer, prostate cancer and ovarian cancer), in order to better understand the most frequent and aggressive primary cancer of the central nervous system, glioblastoma...

The recent and exciting discovery of germline HOXB13 mutations in familial prostate cancer has brought HOX signaling to the forefront of prostate cancer research. An enhanced understanding of HOX signaling, and the co-factors regulating HOX protein specificity and transcriptional regulation, has the high potential to elucidate novel approaches to prevent, diagnose, stage, and treat prostate cancer. Toward our understanding of HOX biology in prostate development and prostate cancer, basic research in developmental model systems as well as other tumor sites provides a mechanistic framework to inform future studies in prostate biology...

Regulation by microRNAs (miRNAs) and modulation of miRNA activity are critical components of diverse cellular processes. Recent research has shown that miRNA-based regulation of the tumor suppressor gene PTEN can be modulated by the expression of other miRNA targets acting as competing endogenous RNAs (ceRNAs). However, the key sequence-based features enabling a transcript to act as an effective ceRNA are not well understood and a quantitative model associating statistical significance to such features is currently lacking...

INTRODUCTION: Quantitative small animal radionuclide imaging studies are often carried out with the intention of estimating the total radioactivity content of various tissues such as the radioactivity content of mouse xenograft tumors exposed to putative diagnostic or therapeutic agents. We show that for at least one specific application, positron projection imaging (PPI) and PET yield comparable estimates of absolute total tumor activity and that both of these estimates are highly correlated with direct well-counting of these same tumors...

Program death receptor-1 (PD-1)/program death ligand 1 (PD-L1) signaling plays an important role in tumor adaptive immune resistance. The streptavidin-granulocyte-macrophage colony stimulating factor (SA-GM-CSF) surface-modified tumor cells vaccine developed through our novel protein-anchor technology could significantly promote the activation of dendritic cells. Although GM-CSF vaccine could significantly increase the number of tumor-specific CD8(+)T-cells, the majority of these CD8(+)T-cells expressed PD-1...
