Article Synopsis
  • Laccase is an enzyme essential for fungi, aiding in processes like lignin breakdown, stress resilience, and fruiting body formation, specifically in white-rot fungi known for wood delignification.
  • The study identified seven laccase family genes through de novo sequencing, revealing various domains and analyzing their physical, phylogenetic, and structural characteristics.
  • Findings included the identification of N-glycosylation sites and significant genetic consistency within laccase sequences, with a phylogenetic analysis showing close relationships among the laccases studied, indicating their similarities in structure and function.

In this study, the α-amylase inhibitory activity, α-glucosidase inhibitory activity, pancreatic lipase inhibitory activity, and Xanthine Oxidase inhibitory activity of the fruiting body extracts of 5 varieties of (AB) were confirmed. First, the α-amylase inhibitory activity of AB12, AB13, AB18, AB34, and AB40 methanol extracts was lower than that of acarbose, a positive control, in all concentration ranges. The α-glucosidase inhibitory activity of the AB40, AB13, and AB12 methanol extracts at the extract concentration of 1.

Purpose: The purposes of this study were to review the types of nurse-led nonpharmacological pain interventions (NPI) offered to cancer patients and/or family caregivers, and to determine a comprehensive and robust estimate of the effect size of nurse-led NPI for cancer patients on various pain-related outcomes.

Design: Systematic review and meta-analysis. Studies assessing nurse-led NPIs targeting cancer patients and published between January 2008 and December 2020 were identified by searching multiple literature databases, including MEDLINE , EMBASE, Google Scholar, Cochrane Library, ProQuest Medical Library, and CINAHL .

This study investigated the changes in (WK) protein expression levels during fermentation in MRS medium supplemented with garlic of WK. WK was first discovered as lactic acid bacteria (LAB) in a Korean fermented cabbage dish known as kimchi. The number of WK cells in MRS medium with garlic (MBCG) and without (MB) after 7 days was 3.

Blue light is an important environmental factor that induces mushroom growth and morphological changes. In this study, after confirming the morphological difference between (LE) under blue light condition (BL) and lightless condition (LL), the increase and decrease in LE protein and the expression of RNA of each protein were confirmed under each condition. LE specimens grown in BL and LL were identified by 253 spots in BL through 2D electrophoresis and LC-MSMS analysis, and 22 types of proteins were identified.

To increase coverage of protein identification of an fruiting body, we analyzed the crude protein fraction of the fruiting body by using a shotgun proteomics approach where 7 MudPIT (Multi-Protein identification Technology) runs were conducted and the MS/MS spectra from the 7 MudPIT runs were merged. Overall, 3093 non-redundant proteins were identified to support the expression of those genes annotated in the genome database of . The physicochemical properties of the identified proteins, i.

Lentinula edodes is one of the most popular edible mushrooms worldwide and contains important medicinal components such as lentinan, ergosterol, and eritadenine. Mushroom metabolism is regulated by the mycelia and fruit body using light; however, in mushrooms, the underlying molecular mechanisms controlling this process as well as light-induced gene expression remain unclear. Therefore, in this study, we compared morphological changes and gene expression in the fruit bodies of L.

Nonalcoholic fatty liver disease is a complex disorder which includes simple steatosis, steatohepatitis, fibrosis and ultimately cirrhosis. Previous studies have reported that genistein, a soy phytoestrogen, attenuates steatohepatitis induced in obese and type 2 diabetic models. Here we investigated the effect of dietary genistein supplementation (0.

Scope: Genistein (GEN) is a compound that has been shown to alleviate hepatic steatosis. Here, we investigated its protective effects against non-alcoholic steatohepatitis (NASH) development in apolipoprotein E-deficient (ApoE(-/-) ) mice fed a high-fat diet (HFD).

Methods And Results: Wild-type and ApoE(-/-) mice were fed an HFD with or without GEN (0.

Mammalian AMP-activated protein kinase (AMPK) acts as a metabolite-sensing protein kinase in multiple tissues. Recent studies have shown that AMPK activation also regulates intracellular signaling pathways involved in cellular survival and apoptosis. Previously, we have reported that AMPK activation alleviates the endoplasmic reticulum (ER) stress-mediated neurotoxicity and tau hyperphosphorylation caused by palmitate.

Obesity and diabetes have been shown to be associated with cognitive impairment or early neurodegeneration. However, the cellular mechanisms that link between these two pathologies have not been clarified. In this study, we treated SH-SY5Y human neuroblastoma cells with palmitate and observed its effect on cell apoptosis and tau hyperphosphorylation.

Previously, we reported that isoflavones exert a protective effect against the endoplasmic reticulum (ER) stress-mediated neuronal degeneration, and ER stress-mediated homocysteine toxicity may play an important role in the pathogenesis of neurodegeneration. Therefore, in this study we investigated the effects of isoflavones (genistein and daidzein) against homocysteine-mediated neurotoxicity in SH-SY5Y human neuroblastoma cells. The treatment of cells with either 17beta-estradiol or isoflavones significantly protected the cells against homocysteine-mediated apoptosis.

Several studies have demonstrated a protective effect of estrogen against the risk of developing neurodegenerative diseases; however, the molecular mechanisms involved have not been fully addressed. Isoflavones have been proposed as potential alternatives to estrogen replacement therapy. Therefore, in the present study, we investigated effects of isoflavones on cell death and tau phosphorylation in SH-SY5Y human neuroblastoma cells.
