<h2 class="jove_title"><a href="https://www.jove.com/video/54529">Identification of Small Molecule-binding Proteins in a Native Cellular Environment by Live-cell Photoaffinity Labeling</a></h2>Sarah A. Head1, Jun O. Liu1,21Department of Pharmacology and Molecular Sciences, Johns Hopkins University School of Medicine, 2Department of Oncology, Johns Hopkins University School of MedicineWe describe here a method for identification of small molecule-binding proteins using photoaffinity labeling. The advantage of this technique is that binding and covalent labeling of the target proteins occurs within the live cellular environment, removing the risk of disrupting native protein structure and binding conditions upon cell lysis. <h2 class="jove_title"><a href="https://www.jove.com/video/54402">Improved Polymerase Chain Reaction-restriction Fragment Length Polymorphism Genotyping of Toxic Pufferfish by Liquid Chromatography/Mass Spectrometry</a></h2>Hajime MiyaguchiNational Research Institute of Police ScienceAn improved polymerase chain reaction-restriction fragment length polymorphism method for genotyping pufferfish species by liquid chromatography/ mass spectrometry is described. A reverse-phase silica monolith column is employed for separating digested amplicons. This method can elucidate the monoisotopic masses of oligonucleotides, which is useful for identifying base composition.<h2 class="jove_title"><a href="https://www.jove.com/video/54429">A Mimic of the Tumor Microenvironment: A Simple Method for Generating Enriched Cell Populations and Investigating Intercellular Communication</a></h2>Jason D. Domogauer, Sonia M. de Toledo, Edouard I. AzzamDepartment of Radiology, New Jersey Medical School, Rutgers UniversityWe adapted a permeable microporous membrane insert to mimic the tumor microenvironment (TME). The model consists of a mixed cell culture, allows simplified generation of highly enriched individual cell populations without using fluorescent tagging or cell sorting, and permits studying intercellular communication within the TME under normal or stress conditions.<h2 class="jove_title"><a href="https://www.jove.com/video/54315">A Method of Targeted Cell Isolation via Glass Surface Functionalization</a></h2>Ali Ansari1, Reema Patel2, Kinsey Schultheis1, Vesna Naumovski3, P. I. Imoukhuede11Department of Bioengineering, University of Illinois at Urbana-Champaign, 2Department of Liberal Arts &amp; Sciences, University of Illinois at Urbana-Champaign, 3Department of Biomedical Engineering, Illinois Institute of TechnologyThis protocol describes customizable surface functionalization of the desthiobiotin, streptavidin, and APTES system in order to isolate specific cell types of interest. In addition, this manuscript covers the applications, optimization, and verification of this process. <h2 class="jove_title"><a href="https://www.jove.com/video/54371">Genetic Engineering of an Unconventional Yeast for Renewable Biofuel and Biochemical Production</a></h2>Ai-Qun Yu1,2, Nina Pratomo1,2, Tee-Kheang Ng1,2, Hua Ling1,2, Han-Saem Cho1,2, Susanna Su Jan Leong1,2,3, Matthew Wook Chang1,21Department of Biochemistry, Yong Loo Lin School of Medicine, National University of Singapore, 2NUS Synthetic Biology for Clinical and Technological Innovation (SynCTI), Life Sciences Institute, National University of Singapore, 3Food Science and Chemical Engineering, Singapore Institute of TechnologyWe herein report methods on the molecular genetic manipulation of the Yarrowia lipolytica Po1g strain for improved gene deletion efficiency. The resulting engineered Y. lipolytica strains have potential applications in biofuel and biochemical production.<h2 class="jove_title"><a href="https://www.jove.com/video/54420">Species Determination and Quantitation in Mixtures Using MRM Mass Spectrometry of Peptides Applied to Meat Authentication</a></h2>Yvonne Gunning1, Andrew D. Watson1, Neil M. Rigby2, Mark Philo1, Joshua K. Peazer1,3, E. Kate Kemsley11Analytical Sciences Unit, Institute of Food Research, 2Institute of Food Research, 3School of Chemistry, University of East AngliaWe present a protocol for identifying and quantifying the components in mixtures of species possessing similar proteins. Mass spectrometry detects peptides for identification, and gives relative quantitation by ratios of peak areas. As a tool food for fraud detection, the method can detect 1% horse in beef.

September 2016-This Month in JoVE: Introducing JoVE Genetics, JoVE Biochemistry, and JoVE Cancer Research

This month we are pleased to introduce three new sections of the JoVE family: Genetics, Biochemistry, and Cancer Research.
JoVE Genetics contains methodologies for exploring all aspects of genes and heredity-from human genetics to model organisms, epigenetics to evolutionary genetics, and gene editing to gene therapy. This section features a method for genotyping pufferfish species by liquid chromatography/mass spectrometry, described by <a href="http://www.jove.com/video/54402/">Miyaguchi</a>. This technique can aid in the appropriate identification and differentiation of toxic species, which is not only important for public health but also for forensics and investigations of food fraud. Also in JoVE Genetics, <a href="http://www.jove.com/video/54371/">Yu et al.</a> report methods for genetically engineering the unconventional yeast Yarrowia lipolytica with improved gene deletion efficiency. The engineered Y. lipolytica strains have potential applications in biofuel and biochemical production.
JoVE Biochemistry comprises methods that advance our understanding of biomolecule structure and function, as well as their interactions and transformations during biological processes. This month, <a href="http://www.jove.com/video/54420">Gunning et al.</a> present a method of meat authentication using multiple reaction monitoring (MRM) mass spectrometry, which identifies peptides and gives relative quantitation for detecting adulterant species in meat mixtures. This method is sensitive enough to detect 1% horsemeat in beef products. Also in JoVE Biochemistry, <a href="http://www.jove.com/video/54529/">Head and Liu</a> describe a method for identifying small molecule-binding proteins using photoaffinity labeling. The target proteins are bound and covalently labeled within the live cellular environment, which helps preserve native protein structure and binding conditions.
JoVE Cancer Research encompasses a broad range of techniques used to advance the understanding and treatment of cancer. This includes methodologies for studying carcinogenesis, developing innovative diagnostics and therapeutics, and uncovering the mechanisms of drug resistance. This month in JoVE Cancer Research, <a href="http://www.jove.com/video/54315">Ansari et al.</a> report a method of targeted cell isolation via glass surface functionalization. This method can identify biomarkers of resistance or susceptibility to anti-angiogenic therapies. Also in this section, <a href="http://www.jove.com/video/54429/">Domogauer et al.</a> present a mixed cell culture model that mimics the tumor microenvironment. With this model, the intercellular communication within the tumor microenvironment can be studied under various conditions.
