Extracellular vesicles: Novel mediator for cell to cell communications in liver pathogenesis
Publication date: Available online 11 November 2017 Source:Molecular Aspects of Medicine Author(s): Pradip B. Devhare, Ratna B. Ray Extracellular vesicles (EVs) are membrane derived nanometer-sized vesicles. EVs are released by normal, diseased, and transformed cells in vitro and in vivo, and carry lipids, proteins, mRNAs, non-coding RNAs, and even DNA out of cells. Transferring biological information via EVs to neighboring cells and inter-cellular communication not only maintain physiological functions, but also involve in the pathogenesis of several diseases, including cancer. The aim of this review is to discuss t...

Mechanisms of dietary flavonoid action in neuronal function and neuroinflammation
Publication date: Available online 9 November 2017 Source:Molecular Aspects of Medicine Author(s): Baptiste N. Jaeger, Sarah L. Parylak, Fred H. Gage Flavonoids are a class of plant-derived dietary polyphenols that have attracted attention for their pro-cognitive and anti-inflammatory effects. The diversity of flavonoids and their extensive in vivo metabolism suggest that a variety of cellular targets in the brain are likely to be impacted by flavonoid consumption. Initially characterized as antioxidants, flavonoids are now believed to act directly on neurons and glia via the interaction with major signal transductio...

PDGF-C and PDGF-D in ocular diseases
Publication date: Available online 27 October 2017 Source:Molecular Aspects of Medicine Author(s): Anil Kumar, Xuri Li PDGFs and their receptors are critical regulators of numerous tissues and organs, including the eye. Extensive studies have shown that PDGFs and their receptors play critical roles in many ocular neovascular diseases, such as neovascular age-related macular degeneration, retinopathy of prematurity, and proliferative vitreoretinopathy. In addition, PDGFs and PDGFRs are also important players in ocular diseases involving the degeneration of retinal neuronal and vascular cells, such as glaucoma and retini...

Platelet-derived growth factor-C and -D in the cardiovascular system and diseases
Publication date: Available online 13 October 2017 Source:Molecular Aspects of Medicine Author(s): Chunsik Lee, Xuri Li The cardiovascular system is among the first organs formed during development and is pivotal for the formation and function of the rest of the organs and tissues. Therefore, the function and homeostasis of the cardiovascular system are finely regulated by many important molecules. Extensive studies have shown that platelet-derived growth factors (PDGFs) and their receptors are critical regulators of the cardiovascular system. Even though PDGF-C and PDGF-D are relatively new members of the PDGF family,...

FFA4 (GPR120) as a fatty acid sensor involved in appetite control, insulin sensitivity and inflammation regulation
Publication date: Available online 12 October 2017 Source:Molecular Aspects of Medicine Author(s): Dong-Soon Im Unsaturated long-chain fatty acids have been suggested to be beneficial in the context of cardiovascular disorders based in epidemiologic studies conducted in Greenland and Mediterranean. DHA and EPA are omega-3 polyunsaturated fatty acids that are plentiful in fish oil, and oleic acid is an omega-9 monounsaturated fatty acid, rich in olive oil. Dietary intake of these unsaturated long-chain fatty acids have been associated with insulin sensitivity and weight loss, which contrasts with the impairment of insuli...

PDGFs and their receptors in vascular stem/progenitor cells: Functions and therapeutic potential in retinal vasculopathy
Publication date: Available online 12 October 2017 Source:Molecular Aspects of Medicine Author(s): Weisi Lu, Xuri Li Vascular stem/progenitor cells (VSCs) include endothelial progenitor cells, smooth muscle progenitor cells, pericytes, and mesenchymal stem cells. VSCs can produce functional and mature vascular cells required to build blood vessels. VSCs therefore play critical roles in vascular repair and regeneration, particularly, in various retinal vasculopathies, in which vascular defects are a devastating pathology. The platelet-derived growth factors (PDGFs) and their receptors (PDGFRs) are important regulators o...

Single cell epigenome sequencing technologies
Publication date: Available online 21 September 2017 Source:Molecular Aspects of Medicine Author(s): Lu Wen, Fuchou Tang Epigenetic regulation plays crucial roles in the development and disease processes. Since different cell types with distinct epigenetic characteristics are always intermingled together in the tissues or organs, the single cell analysis provides a universal resolution for dissecting their intrinsic complexities. In this review, we discuss recent advances of developing single cell epigenome sequencing techniques for profiling DNA modifications (5mC, 5hmC, 5fC and 5caC), chromatin accessibility, histone...

Single cell analysis of normal and leukemic hematopoiesis
Publication date: Available online 8 September 2017 Source:Molecular Aspects of Medicine Author(s): Benjamin J. Povinelli, Alba Rodriguez-Meira, Adam J. Mead The hematopoietic system is well established as a paradigm for the study of cellular hierarchies, their disruption in disease and therapeutic use in regenerative medicine. Traditional approaches to study hematopoiesis involve purification of cell populations based on a small number of surface markers. However, such population-based analysis obscures underlying heterogeneity contained within any phenotypically defined cell population. This heterogeneity can only b...
