    Lipid-exchange Rate Assay for Lipid Droplet Fusion in Live Cells
    Authors:  Jia Wang, Boon Tin Chua, Peng Li and Feng-Jung Chen, date: 07/20/2019, view: 817, Q&A: 0
    [Abstract] Lipid droplets (LDs) are central organelles in maintaining lipid homeostasis. Defective LD growth often results in the development of metabolic disorders. LD fusion and growth mediated by cell death–inducing DNA fragmentation factor alpha (DFFA)-like effector (CIDE) family proteins are crucial for various biological processes including unilocular ...
    Determining Oxidative Damage by Lipid Peroxidation Assay in Rat Serum
    Authors:  Qian Tang, Yu-Wen Su and Cory J. Xian, date: 06/20/2019, view: 1232, Q&A: 0
    [Abstract] It has been well-established that malondialdehyde (MDA), which is generated during the process of lipid peroxidation, is a commonly known biomarker for oxidative stress. Therefore, the serum levels of MDA are detected by using the lipid peroxidation assay with commercially available kit to determine the induction of oxidative stress in rat models.
    Insulin Tolerance Test under Anaesthesia to Measure Tissue-specific Insulin-stimulated Glucose Disposal
    [Abstract] Insulin resistance is a pathophysiological state defined by impaired responses to insulin and is a risk factor for several metabolic diseases, most notably type 2 diabetes. Insulin resistance occurs in insulin target tissues including liver, adipose and skeletal muscle. Methods such as insulin tolerance tests and hyperinsulinaemic-euglycaemic ...
    Isolation and Analysis of Stromal Vascular Cells from Visceral Adipose Tissue
    Authors:  Jessica Vu and Wei Ying, date: 08/20/2017, view: 6914, Q&A: 0
    [Abstract] The obesity epidemic is the underlying driver of the type 2 diabetes mellitus epidemic. A remarkable accumulation of various pro-inflammatory immune cells in adipose tissues is a hallmark of obesity and leads to pathogenesis of tissue inflammation and insulin resistance. Here, we describe a detailed protocol to isolate adipose tissue stromal ...
    Isolation and Expansion of Mesenchymal Stem Cells from Murine Adipose Tissue
    Authors:  Natalia V. Andreeva, Alexandra A. Dalina and Alexander V. Belyavsky, date: 08/20/2017, view: 6391, Q&A: 1
    [Abstract] Mesenchymal stem cells (MSCs) are currently intensively studied due to significant promise which they represent for successful implementations of future cell therapy clinical protocols. This in turn emphasizes importance of careful preclinical studies of MSC effects in various murine disease models. The appropriate cell preparations with ...
    Secretion of Adipsin as an Assay to Measure Flux from the Endoplasmic Reticulum (ER)
    Authors:  Alexandria Brumfield, Natasha Chaudhary and Timothy E. McGraw, date: 04/05/2017, view: 4326, Q&A: 0
    [Abstract] In this protocol we describe a quantitative biochemical assay to assess the efficiency of endoplasmic reticulum (ER) to Golgi protein transport in adipocytes (Bruno et al., 2016). The assay takes advantage of the fact that adipocytes secrete various bioactive proteins, known as adipokines. As a measure of ER to Golgi flux we determine the ...
    Isolation of Lymphocytes from Murine Visceral Adipose Tissue
    Authors:  Sonja Valentić, Felix M. Wensveen and Bojan Polić, date: 12/05/2015, view: 10373, Q&A: 1
    [Abstract] Several studies have shown that the detrimental influence of abdominal obesity on metabolic processes is mediated by the intra-abdominal fat depot. Visceral adipose tissue has been shown to be an independent risk factor for coronary heart disease, hypertension, impaired glucose tolerance and Diabetes Mellitus Type 2 (DM2). Diet-induced obesity in ...
    Excision of Visceral Adipose Tissue from Live Mice (VATectomy)
    Authors:  Marko Šestan, Felix M. Wensveen and Bojan Polić, date: 12/05/2015, view: 8052, Q&A: 0
    [Abstract] The visceral adipose tissue (VAT) has been shown to play an important role in various biological functions. It is a storage depot for nutrients and it is an important endocrine organ producing hormones that control systemic metabolism (McGown et al., 2014). Importantly, following diet-induced obesity, VAT accumulates a large number of ...
    Isolation of Murine Adipose Tissue-derived Mesenchymal Stromal Cells (mASCs) and the Analysis of Their Proliferation in vitro
    Authors:  Per Anderson, Ana Belén Carrillo-Gálvez and Francisco Martín, date: 11/05/2015, view: 6574, Q&A: 0
    [Abstract] Mesenchymal stromal cells (MSCs) are non-hematopoietic, perivascular cells which support hematopoiesis and are thought to participate in tissue repair in vivo. MSCs can be isolated from various tissues and organs and are defined in vitro as plastic adherent cells expressing CD73, CD90, CD105 (human MSCs) or CD29, CD44, sca-1 ...
