Phospholipid-mediated signal transduction plays a key role in responses to environmental changes, but little is known about the role of phospholipid signalling in microorganisms. Heat stress (HS) is one of the most important environmental factors. Our previous study found that HS could induce the biosynthesis of the secondary metabolites, ganoderic acids (GA). Here, we performed a comprehensive mass spectrometry-based analysis to investigate HS-induced lipid remodelling in Ganoderma lucidum. In particular, we observed a significant accumulation of phosphatidic acid (PA) upon HS...

Laccases catalyze the oxidation of various aromatic organic compounds concomitantly with molecular oxygen reduction to water. Triphenylmethane dyes are synthetic compounds widely used in diverse industries. Their removal from effluents is difficult, due to their high degree of structural complexity; hence, their high concentration in effluents cause a negative impact on the environment. In the present work, molecular docking was used to evaluate interactions between rGlLCC1 or rPOXA 1B enzymes with Crystal Violet (CV) or Malachite Green (MG) dyes...

Doxorubicin (DOX) is a widely used anthracycline derivative anticancer drug, but the use of DOX in clinical applications is limited by its cardiotoxicity. In the current research, we were aiming to assess the effects of Ganoderma lucidum polysaccharides (GLPS) on DOX-induced cardiotoxicity and to illustrate the associated mechanisms. H9c2 rat cardiomyocytes were treated with DOX in the absence or presence of GLPS, and we found GLPS treatment ameliorated DOX-induced H9c2 cell death. Moreover, results of in vivo studies indicated that GLPS significantly decreased the serum levels of lactate dehydrogenase (LDH), creatine kinase (CK) and aspartate aminotransferase (AST) and attenuated DOX-induced histological changes of the heart tissues...
