Project description:The study aimed the effects of Sasa quelpaertensis leaf hot water extract (SQH) on anti-fatigue function and the global gene expression pattern in muscle tissue. When rat skeletal muscle cells were cultured in hypoxic condition, the levels of lactate and lactate dehydrogenase (LDH) was increased approximately more than 2-fold, but SQH decreased effectively these levels. Thus, we assessed the exercise and fatigue recovery function using several physical biomarkers such as glycogen, lactate and so on in high intensity exercise mice. The mice were divided into three groups; Normal Control (NC), Exercise Control (EC), and Exercise SQH (ES) by oral administered at 50mg/kg/day for 7 days. After excessive swimming,the ES group showed increases serum glucose and decrease serum lactate than EC group. Lactate content in muscle was lower ES group than EC group. Glycogen contents in muscle and liver were higher ES group than EC group. And, SQH administration increased the expression of phospho-Acetyl-CoA (p-ACC), and reduced the expression of phospho-AMP-activated protein kinase (p-AMPK) and GLUT4 in in-vivo model. Also, genome wide expression profiles of tissue were determined by RNA sequencing. SQH up-regulates and down-regulates several genes associated with fatigue. In conclusion, this study suggested that SQH are effective for anti-fatigue agent.
Project description:To investigate effects of intake of mulberry leaf extracts on hypercholesterolemia, we performed gene expression profiling on rat liver by microarray analysis. Microarray analysis revealed that mulberry leaf extracts up-regulated the gene expression involved in suppression of cholesterol synthesis and stimulation of innate-adaptive Immunity.

Microarray analysis revealed that mulberry leaf extracts up-regulated the gene expression involved in suppression of cholesterol synthesis and stimulation of innate-adaptive Immunity. Mice were fed a high-cholesterol diet without/with orally administration of mulberry leaf extracts for 4 weeks. Livers were taken for RNA extraction and hybridization on Agilent microarrays.
Project description:Members of the Caryophyllaceae Juss. family possess anabolic, adaptogenic, radioprotective, antitumoral and hemorheological properties and have been used in medical practice for the treatment of various inflammatory disorders. Macrophages are key immune cells that coordinate the inflammatory reaction. To identify the effects of Silene sendtneri and Silene roemeri on macrophage activation, primary human macrophages were cultured with extracts of these plants .We used microarrays to determine the global expression pattern induced by the extracts in macrophages.
Project description:The COVID-19 pandemic has unveiled an urgent need for new anti-virals to control emerging infectious diseases and potential future pandemics. Classic anti-virals are currently designed to directly interfere with pathogens. However, anti-virals are often insufficient to rapidly clear infections in the absence of an effective immune response. Immunotherapy could complement the use of anti-virals, however its application to infectious diseases remains largely unexplored. In this work, we found that the anti-viral drug remdesivir has previously unknown immunomodulatory properties which contribute to its therapeutic effect against SARS-CoV-2. These properties are due to remdesivir metabolite, GS-441524, acting as an Adenosine A2A Receptor antagonist, a function that is distinct from its intrinsic anti-viral activity. Our findings support a new rationale for the design of next-generation anti-viral agents with dual – immunomodulatory and intrinsic - anti-viral properties. These compounds could represent game-changing therapies to control emerging viral diseases and future pandemics.
