Proteomics is a technology that allows to decipher the molecular networks involved in the regulation of biological processes such as spermatogenesis. Sertoli cells (SCs) are key players in the paracrine control of this process. Envisioning to increase the knowledge on the molecular networks harbored in SCs, we propose a methodology based on GeLC-MS/MS for the characterization of these cells' proteome. Proteins are separated by SDS-PAGE hyphenated to HPLC and identified by mass spectrometry. The integration of data with bioinformatics tools such as ClueGO + CluePedia from Cytoscape allows the identification of the biological pathways more prevalent in SCs, and that might be modulated by pathophysiological conditions...

Sertoli cells are crucial for germ cell support, create a suitable environment for spermatogenesis, and integrate information from the nervous system and germ cell line. To fully understand the role of Sertoli cells, it is necessary to characterize the protein-protein interactions. Identifying the interactome of a given protein may provide leads about the role and molecular mechanism of such protein in Sertoli cells. One of the techniques to characterize protein interactomes consists of co-immunoprecipitation followed by mass spectrometry or Western blot...

The trend towards precision-based therapeutic approaches dictated by molecular alterations offers substantial promise for men with metastatic castration resistant prostate cancer (mCRPC). However, current approaches for molecular characterization are primarily tissue based, necessitating serial biopsies to understand changes over time and are limited by the challenges inherent to extracting genomic material from predominantly bone metastases. Therefore, a circulating tumor cell (CTC)-based assay was developed to determine gene expression across a panel of clinically relevant and potentially actionable prostate cancer related genes...

BACKGROUND: The incidence of obesity is rising, particularly among women. Microvascular dysfunction is more common with female sex, obesity, and hyperlipidemia and predicts adverse cardiovascular outcomes, but the molecular mechanisms are unclear. Because obesity is associated with mineralocorticoid receptor (MR) activation, we tested the hypothesis that MR in endothelial cells contribute to sex differences in resistance vessel dysfunction in response to cardiometabolic risk factors. METHODS AND RESULTS: Male and female endothelial cell-specific MR knockout mice and MR-intact littermates were randomized to high-fat-diet-induced obesity or obesity with hyperlipidemia induced by adeno-associated virus-based vector targeting transfer of the mutant stable form (DY mutation) of the human PCSK9 (proprotein convertase subtilisin/kexin type 9) gene and compared with control diet...

We investigated plasma microRNA (miRNA) profiles associated with variation of hyperglycemia, measured as hemoglobin A 1c (HbA 1c ), in two panels of patients with type 1 diabetes (T1D). Using the HTG Molecular Diagnostics EdgeSeq platform, 2,083 miRNAs were measured in plasma from 71 patients included in a screening panel. Quantitative real-time polymerase chain reaction was used to measure the candidate miRNAs in plasma from 95 patients included in an independent replication panel. We found 10 miRNAs replicated in both panels and four with high statistical significance...

Invariant Natural Killer T (iNKT) cells are a heterogeneous innate T cell population that recognizes lipid antigens. Despite the monospecific nature of their T cell receptor, iNKT cells differentiate into stable sublineages during thymic development, before foreign antigen encounter. How iNKT cell subsets acquire and maintain their functional programs is a central question in innate lymphocyte biology. Global transcriptional and epigenetic profiling of iNKT subsets has provided insights into the internal wiring of these subsets that defines their identity...

STUDY QUESTION: Is endometrial recurrent implantation failure (RIF) only a matter of an asynchronous (displaced) window of implantation (WOI), or could it also be a pathological (disrupted) WOI? SUMMARY ANSWER: Our predictive results demonstrate that both displaced and disrupted WOIs exist and can present independently or together in the same RIF patient. WHAT IS KNOWN ALREADY: Since 2002, many gene expression signatures associated with endometrial receptivity and RIF have been described...

The enormous diversity of proteoforms produces tremendous complexity within cellular proteomes, facilitates intricate networks of molecular interactions, and constitutes a formidable analytical challenge for biomedical researchers. Currently, quantitative whole-proteome profiling often relies on non-targeted liquid chromatography-mass spectrometry (LC-MS), which samples proteoforms broadly, but can suffer from lower accuracy, sensitivity, and reproducibility compared with targeted LC-MS. Recent advances in bottom-up proteomics using targeted LC-MS have enabled previously unachievable identification and quantification of target proteins and posttranslational modifications within complex samples...

Acral melanoma (AM) is a rapidly progressing subtype of melanoma with poor prognosis. The complete array of molecular changes that occur during AM metastasis remains unclear. In this study, we compared the gene expression profiles of six primary and 12 lymph node metastatic AM samples by tissue microarray analysis. We found that the expression levels of 396 genes were increased, and that of 766 genes were decreased in the metastatic tissues compared with that in the primary tumors. The top 19 genes upregulated in the metastatic tissue specimens were selected for high-content short interfering (si)RNA screening...

Exosomes are membrane-bound, virus-size vesicles present in circulating blood. Tumor cells are avid producers of exosomes, which are thought to mimic molecular features of parent tumor cells. T-cell Immunoglobulin- and Mucin-domain-containing molecule 3 (Tim-3) is one of the next generation immune checkpoints and can be activated by its ligand Galectin-9, negatively regulating anti-tumor immune response. However, the characteristics of plasma exosomal Tim-3/Galectin-9 (Exo-T/G) in cancer remained unknown. Our study aimed to investigate the expression patterns and clinical value of plasma exosomal total protein (Exo-pro) and Exo-T/G in non-small cell lung caner (NSCLC)...

The structural nature of the solvation shells of an iodate ion, which is known to be a polyoxy-anion with a large cationic centre, is investigated by means of Born-Oppenheimer molecular dynamics (BOMD) simulations using BLYP and the dispersion corrected BLYP-D3 functionals. The iodate ion is found to have two distinct solvation regions around the positively charged iodine (iodine solvation shell or ISS) and the negatively charged oxygens (oxygen solvation shell or OSS). We have looked at the spatial, orientational, and hydrogen bond distributions of water in the two solvation regions...

Odorant-binding proteins (OBPs) in insects are essential for mating and oviposition host selection. How these OBPs respond to different hosts at the mRNA level and their effects on behavior remain poorly characterized. The oriental fruit fly Bactrocera dorsalis is a highly invasive agricultural pest with an extremely broad host range and high fecundity. Based on our previously constructed B. dorsalis transcriptome, six OBPs that were differentially expressed during three different physiological adult stages were identified...

Pheochromocytomas and paragangliomas (PCC/PGLs) are rare neuroendocrine tumors that are unusually diverse in metabolic profiles, in classes of molecular alterations and across a large number of altered genes. The Cancer Genome Atlas (TCGA) comprehensively profiled the molecular landscape of PCC/PGLs and identified novel genomic alterations and a new molecular classification of PCC/PGLs. In this review, we discuss the significant clinico-molecular findings of this integrated profiling study. We then review the molecular data of the TCGA cohort centering around known markers of sympathoadrenal cell lineage to better understand chromaffin cell biology...

Synovial sarcoma is an aggressive mesenchymal malignancy characterized by unique gene fusions. Tissue culture cells are essential tools for further understanding tumorigenesis and anti-cancer drug development; however, only a limited number of well-characterized synovial sarcoma cell lines exist. Thus, the objective of this study was to establish a patient-derived synovial sarcoma cell line. We established a synovial sarcoma cell line from tumor tissue isolated from a 72-year-old female patient. Prepared cells were analyzed for the presence of gene fusions by fluorescence in situ hybridization, RT-PCR, and karyotyping...
