BACKGROUND: The detection of somatic mutations in primary tumors is critical for the understanding of cancer evolution and targeting therapy. Multiple technologies have been developed to enable the detection of such mutations. Next generation sequencing (NGS) is a new platform that is gradually becoming the technology of choice for genotyping cancer samples, owing to its ability to simultaneously interrogate many genomic loci at massively high efficiency and increasingly lower cost. However, multiple barriers still exist for its broader adoption in clinical research practice, such as fragmented workflow and complex bioinformatics analysis and interpretation...

We developed a multi-platform approach for the metabolome exploration of rat brain tissue, using liquid chromatography coupled with mass spectrometry (LC-MS), nuclear magnetic resonance spectroscopy (NMR) and gas-chromatography coupled with mass spectrometry (GC-MS). The critical steps for metabolite exploration of cerebral tissues are tissue lysis and metabolites extraction. We first evaluated the impact of freeze-drying compared to wet tissue metabolites extraction using NMR and LC-MS with a reversed phase liquid chromatography...

Detergents and salts are widely used in lysis buffers to enhance protein extraction from biological samples, facilitating in-depth proteomic analysis. However, these detergents and salt additives must be efficiently removed from the digested samples prior to LC-MS/MS analysis to obtain high-quality mass spectra. Although filter-aided sample preparation (FASP), acetone precipitation (AP), followed by in-solution digestion, and strong cation exchange-based centrifugal proteomic reactors (CPRs) are commonly used for proteomic sample processing, little is known about their efficiencies at removing detergents and salt additives...

REVIEW
Clarisse van der Feltz, Aaron A Hoskins
The spliceosome is an extraordinarily dynamic molecular machine in which significant changes in composition as well as protein and RNA conformation are required for carrying out pre-mRNA splicing. Single-molecule fluorescence resonance energy transfer (smFRET) can be used to elucidate these dynamics both in well-characterized model systems and in entire spliceosomes. These types of single-molecule data provide novel information about spliceosome components and can be used to identify sub-populations of molecules with unique behaviors...

Cryo-electron microscopy (cryo-EM) techniques have made a huge advancement recently, providing close to atomic resolution of the structure of protein complexes. Interestingly, this imaging technique can be performed in cells, giving access to the molecular machines in their natural context, therefore bridging structural and cell biology. However, in situ structural electron microscopy faces one major challenge, which is the ability to focus on specific subcellular regions to capture the objects of interest...

Correlative light and electron microscopy (CLEM) is a powerful tool to perform ultrastructural analysis of targeted tissues or cells. The large field of view of the light microscope (LM) enables quick and efficient surveys of the whole specimen. It is also compatible with live imaging, giving access to functional assays. CLEM protocols take advantage of the features to efficiently retrace the position of targeted sites when switching from one modality to the other. They more often rely on anatomical cues that are visible both by light and electron microscopy...

Correlative light and electron microscopy (CLEM) is a scientific method covered by a broad range of techniques. The path taken to explore a scientific question is often driven both by the question and the technology available. Yet, one common step to all CLEM workflows is the registration of the multimodal images to assign a fluorescent signal to an ultrastructure. The manual relocation and registration of light microscopy and electron microscopy images can be challenging and time-consuming (Muller-Reichert & Verkade, 2014)...

Combining in vivo imaging with electron microscopy (EM) uniquely allows monitoring rare and critical events in living tissue, followed by their high-resolution visualization in their native context. A major hurdle, however, is to keep track of the region of interest (ROI) when moving from intravital microscopy (IVM) to EM. Here, we present a workflow that relies on correlating IVM and microscopic X-ray computed tomography to predict the position of the ROI inside the EM-processed sample. The ROI can then be accurately and quickly targeted using ultramicrotomy and imaged using EM...

Linking cellular structure and function has always been a key goal of microscopy, but obtaining high resolution spatial and temporal information from the same specimen is a fundamental challenge. Two-photon (2P) microscopy allows imaging deep inside intact tissue, bringing great insight into the structural and functional dynamics of cells in their physiological environment. At the nanoscale, the complex ultrastructure of a cell's environment in tissue can be reconstructed in three dimensions (3D) using serial block face scanning electron microscopy (SBF-SEM)...

While fluorescence microscopy provides tools for highly specific labeling and sensitive detection, its resolution limit and lack of general contrast has hindered studies of cellular structure and protein localization. Recent advances in correlative light and electron microscopy (CLEM), including the fully integrated CLEM workflow instrument, the FEI CorrSight with MAPS, have allowed for a more reliable, reproducible, and quicker approach to correlate three-dimensional time-lapse confocal fluorescence data, with three-dimensional focused ion beam-scanning electron microscopy data...

Embryonic stem cells (ESCs) can be established as permanent cell lines, and their potential to differentiate into adult tissues has led to widespread use for studying the mechanisms and dynamics of stem cell differentiation and exploring strategies for tissue repair. Imaging live ESCs during development is now feasible due to advances in optical imaging and engineering of genetically encoded fluorescent reporters; however, a major limitation is the low spatio-temporal resolution of long-term 3-D imaging required for generational and neighboring reconstructions...

A commercial liquid chromatography/drift tube ion mobility-mass spectrometer (LC/IM-MS) was evaluated for its utility in global metabolomics analysis. Performance was assessed using twelve targeted metabolite standards where the limit of detection (LOD), linear dynamic range, resolving power, and collision cross section (Ω), is reported for each standard. Data was collected in three different instrument operation modes: flow injection analysis with IM-MS (FIA/IM-MS), LC/MS and LC/IM-MS. Metabolomics analyses of human plasma and HaCaT cells were used to compare the above three operation modes...
