    Evoked Potential Recordings of Auditory Brainstem Activity in the Mouse: An Optimized Method for the Assessment of Hearing Function of Mice
    Author:  Neil J. Ingham, date: 12/05/2019, view: 68, Q&A: 0
    [Abstract] Hearing loss is a common sensory deficiency suffered by millions worldwide. It is a heterogeneous condition and genetics plays a critical role in its etiology. Gene variants can fundamentally alter hearing function, or predispose the auditory system towards loss of function resulting from other factors. In mouse studies of hearing loss and gene ...
    Trial-based Discrimination Procedure for Studying Drug Relapse in Rats
    [Abstract] In abstinent drug addicts, cues formerly associated with drug-taking experiences gain relapse-inducing potency (‘incubate’) over time. Animal models of incubation may help in developing treatments for relapse prevention. However, these models have primarily focused on the role of conditioned stimuli (CSs) signaling drug delivery and not ...
    Quantification of Nitric Oxide and Reactive Oxygen Species in Leishmania-infected J774A.1 Macrophages as a Response to the in vitro Treatment with a Natural Product Compound
    Authors:  Kalliopi Karampetsou, Olga S. Koutsoni and Eleni Dotsika, date: 12/05/2019, view: 65, Q&A: 0
    [Abstract] Leishmaniasis is a parasitic disease caused by the obligatory intracellular protozoa Leishmania spp. Current therapeutic options are limited and thus, drug discovery against leishmaniasis is very important. Nevertheless, there is a great difficulty to develop therapeutic strategies against the disease because the parasite deploys various ...
    Intra-arterial Drug Delivery to the Ischemic Brain in Rat Middle Cerebral Artery Occlusion Model
    [Abstract] Rat transient middle cerebral artery occlusion (tMCAO) model is one of the most commonly used animal models in ischemic stroke studies. In the model, increasing safety and efficacy of therapeutic agent administration, such as stem cells and drugs directly to the ischemic brain using the internal carotid artery (ICA) is essential, because using the ...
    Mapping the Mechanome–A Protocol for Simultaneous Live Imaging and Quantitative Analysis of Cell Mechanoadaptation and Ingression
    [Abstract] Mechanomics, the mechanics equivalent of genomics, is a burgeoning field studying mechanical modulation of stem cell behavior and lineage commitment. Analogous to mechanical testing of a living material as it adapts and evolves, mapping of the mechanome necessitates the development of new protocols to assess changes in structure and function in ...
    ELISA Based Protein Ubiquitylation Measurement
    Authors:  Yuka Kamada, Ryosuke Fukuda and Tsukasa Okiyoneda, date: 11/20/2019, view: 371, Q&A: 0
    [Abstract] Ubiquitylation is a common post-translational modification of cellular proteins that results in proteasomal and lysosomal degradations. Ubiquitylation is generally measured by methods such as immunoblotting using anti-ubiquitin antibodies after isolating the protein-of-interest by denaturing immunoprecipitation. The following protocol can be used ...
    Bacterial Synchronized Transfer Assays in Bone Marrow Derived Macrophages

    [Abstract] Merocytophagy (“mero”, Greek for partial; “cytophagy” for cell eating) is a process by which cells acquire microbes and cytosolic material through phagocytosis of a small portion of neighboring cells upon cell-cell contact. Cell-cell contact dependent transfer events can be assessed through co-incubation of differently labeled cells. With these ...
    Labeling and Isolation of Fluorouracil Tagged RNA by Cytosine Deaminase Expression
    Authors:  Harihar Basnet and Joan Massague, date: 11/20/2019, view: 250, Q&A: 0
    [Abstract] Tissues are comprised of different cell types whose interactions elicit distinct gene expression patterns that regulate tissue formation, regeneration, homeostasis and repair. Analysis of these gene expression patterns require methods that can capture as closely as possible the transcriptomes of cells of interest in their tissue microenvironment. ...
    Opto-magnetic Selection and Isolation of Single Cells
    Authors:  Loïc Binan, Joannie Roy and Santiago Costantino, date: 11/20/2019, view: 342, Q&A: 0
    [Abstract] Capturing single cells from large heterogenous populations based solely on observable traits is necessary for many cell biology applications and remains a major technical challenge. The protocol we present allows the isolation of viable and metabolically active cells selected for their shape, migration speed, contact to other cells, or ...
    Isolation and Quantification of Metabolite Levels in Murine Tumor Interstitial Fluid by LC/MS
    Authors:  Mark R Sullivan, Caroline A Lewis and Alexander Muir, date: 11/20/2019, view: 668, Q&A: 0
    [Abstract] Cancer is a disease characterized by altered metabolism, and there has been renewed interest in understanding the metabolism of tumors. Even though nutrient availability is a critical determinant of tumor metabolism, there has been little systematic study of the nutrients directly available to cancer cells in the tumor microenvironment. Previous ...
