Recent advances in combining flow cytometry and mass spectrometry have led to the development of mass cytometry, allowing for the interrogation of complex cell populations on an unprecedented scale. The volumes and high dimensionality of mass cytometry data pose significant challenges in terms of analysis and visualization. We implement a method called Radviz (1-3), where multidimensional single cell data can be visualized as a projection that maintains the original dimensions and data complexity whilst facilitating analysis and visualization...

Advances in scientific techniques have provided researchers with exceptional new opportunities to identify and monitor changes between different cancer types, during different stages of progression, between individual tumor cells and in the surrounding stroma. The wealth of information that can be obtained from new scientific techniques places additional requirements on the conventional cancer models. New models that could be used to rapidly access the (potential) functional importance of newly identified (epi)genetic and proteomic changes and test the efficacy on emerging (combinatorial) therapies are desperately required...

Diversity Outbred (DO) mice are a multiparental advanced generation intercross population derived from eight inbred strains which are genetically very diverse. They are maintained as an outbred population using a randomized mating design. Thus DO mice represent an ideal population to map phenotypic traits. Here, we provide a case study in which male DO mice were exposed to benzene and phenotyped for the number of micronucleated reticulocytes. We provide step-by-step R scripts for the analysis of phenotypes, genotypes, mapping of resistance gene loci and identification of candidate genes...

The aim of expression Quantitative Trait Locus (eQTL) mapping is the identification of DNA sequence variants that explain variation in gene expression. Given the recent yield of trait-associated genetic variants identified by large-scale genome-wide association analyses (GWAS), eQTL mapping has become a useful tool to understand the functional context where these variants operate and eventually narrow down functional gene targets for disease. Despite its extensive application to complex (polygenic) traits and disease, the majority of eQTL studies still rely on univariate data modeling strategies, i...

The abundance of existing functional genomics studies permits an integrative approach to interpreting and resolving the results of diverse systems genetics studies. However, a major challenge lies in assembling and harmonizing heterogeneous data sets across species for facile comparison to the positional candidate genes and coexpression networks that come from systems genetic studies. GeneWeaver is an online database and suite of tools at www.geneweaver.org that allows for fast aggregation and analysis of gene set-centric data...

REVIEW
Lucas T Vu, Robert Bowser
Amyotrophic lateral sclerosis (ALS) is a highly heterogeneous disease with no effective treatment. Drug development has been hampered by the lack of biomarkers that aid in early diagnosis, demonstrate target engagement, monitor disease progression, and can serve as surrogate endpoints to assess the efficacy of treatments. Fluid-based biomarkers may potentially address these issues. An ideal biomarker should exhibit high specificity and sensitivity for distinguishing ALS from control (appropriate disease mimics and other neurologic diseases) populations and monitor disease progression within individual patients...

Treatment-related neurotoxicity is a potentially life-threatening clinical condition that can represent a diagnostic challenge. Differentiating diagnoses between therapy-associated brain injury and recurrent disease can be difficult, and the immediate recognition of neurotoxicity is crucial to providing correct therapeutic management, ensuring damage reversibility. For these purposes, the knowledge of clinical timing and specific treatment protocols is extremely important for interpreting MRI patterns. Neuroradiologic findings are heterogeneous and sometimes overlapping, representing the compounding effect of the different treatments...

Metastasis is one of the most characteristic yet problematic behaviors of cancer cells. Stage IV breast cancer accounts for a large portion of breast cancer-related morbidity and mortality. Despite early detection and improvement in survival owing to advancements in biomedical research and overall improvement of the health system, 6-10% of patients present with stage IV disease in the developed world, with a higher incidence noted elsewhere. Despite advances in biomedical research into cancer, up to 70-80% of patients with stage IV breast cancer die of cancer in 5 years, a disproportionally higher mortality compared with non-metastatic breast cancer...

BACKGROUND: Although quality of life (QOL) is one of the most important considerations in patients treated with anticancer therapies, desirable regimens for neoadjuvant chemotherapy including QOL in locally advanced urothelial carcinoma remain unclear. The present study evaluated the influence of neoadjuvant platinum-based chemotherapy on QOL in patients with locally advanced urothelial carcinoma. METHODS: Between June 2013 and March 2016, 83 urothelial carcinoma patients who received two courses of neoadjuvant chemotherapy were enrolled in this prospective observational study...

BACKGROUND: Left heart valve thickening (LVT) was described in patients with light-chain amyloidosis (AL). This phenomenon reflects likely infiltration of the valve by amyloid proteins. However, the prevalence of LVT and its prognostic value have not been investigated in patients with AL. METHODS AND RESULTS: Comprehensive transthoracic echocardiography was performed at baseline in 150 patients [median age 68 (33-87) years; 59% male] with confirmed AL. The presence of abnormal mitral and/or aortic valve thickening (>3 mm) was assessed in all included patients...

The incidence of thyroid cancer has been greatly increasing. Several studies aimed to investigate biomarkers for prediction of thyroid cancer. Some of these studies have suggested that thyroid autoantibodies (TAb) could be used as predictors of thyroid cancer risk, but the correlation between TAb and PTC is still a matter of debate. The aim of this study is to evaluate thyroid autoimmunity and TAbs in patients with PTC and benign multinodular goiter (MNG) to investigate if TAbs and autoimmune thyroid disease (ATD) could predict thyroid malignancy...

During the last decades, imaging mass spectrometry has gained significant relevance in biomedical research. Recent advances in imaging mass spectrometry have paved the way for in situ studies on drug development, metabolism and toxicology. In contrast to whole-body autoradiography that images the localization of radiolabeled compounds, imaging mass spectrometry provides the possibility to simultaneously determine the discrete tissue distribution of the parent compound and its metabolites. In addition, imaging mass spectrometry features high molecular specificity and allows comprehensive, multiplexed detection and localization of hundreds of proteins, peptides and lipids directly in tissues...

Tunneling nanotubes (TNTs) are ultrafine, filamentous actin-based cytoplasmic extensions which form spontaneously to connect cells at short and long-range distances. We have previously described long-range intercellular communication via TNTs connecting mesothelioma cells in vitro and demonstrated TNTs in intact tumors from patients with mesothelioma. Here, we investigate the ability of TNTs to mediate a viral thymidine kinase based bystander effect after oncolytic viral infection and administration of the nucleoside analog ganciclovir...
