Ganoderma lucidum is a medicinal macrofungus that is widely used in traditional Chinese medicine. Nonetheless, the scarcity of basic biological studies of this organism has hindered the further development of its commercial value. The pH-responsive transcription factor PacC/Rim101 governs the adaptation to environmental pH, the development and the secondary metabolism of many fungi. In this study, a homologue of PacC/Rim101 that encodes GlPacC was identified in the higher basidiomycete G. lucidum GlPacC is composed of 807 amino acids and contains three typical C2H2 zinc-finger domains, two potential PEST domains, a putative PKA phosphorylation site, and a putative nuclear localization signal (NLS)...

Plant defensins are plant defence peptides that have many different biological activities, including antifungal, antimicrobial, and insecticidal activities. A cDNA (EgDFS) encoding defensin was isolated from Elaies guineensis. The open reading frame of EgDFS contained 231 nucleotides encoding a 71-amino acid protein with a predicted molecular weight at 8.69 kDa, and a potential signal peptide. The eight highly conserved cysteine sites in plant defensins were also conserved in EgDFS. The EgDFS sequence lacking 30 amino acid residues at its N-terminus (EgDFSm) was cloned into Escherichia coli BL21 (DE3) pLysS and successfully expressed as a soluble recombinant protein...

To examine the role of oral Ganoderma spore oil in cardiovascular disease, we used transverse aortic constriction (TAC) in mice to model pressure overload-induced cardiomyopathy. Our preliminary results demonstrated a potential cardioprotective role for spore oil extracted from Ganoderma. We found that Ganoderma treatment normalized ejection fraction and corrected the fractional shortening generated by TAC. We also found evidence of reduced left ventricular hypertrophy as assessed by left ventricular end diastolic diameter...

Development of sequence-characterized amplified region (SCAR) markers from random-amplified polymorphic DNA (RAPD) fragments is a valuable molecular approach for the genetic identification of different species. By using SCAR markers, molecular analysis is reduced to a simple polymerase chain reaction (PCR) analysis using primers designed from the amplicon sequence of RAPD. In this study, the DNA fragments from an improved RAPD amplification of Ganoderma species were cloned into a pGM-T vector; positive clones were identified by PCR amplification and enzymatic digestion, and finally, DNA fragments were sequenced using the Sanger sequencing method for developing the SCAR markers...

Understanding the mechanism of interaction between the oil palm and its key pathogen, Ganoderma spp. is crucial as the disease caused by this fungal pathogen leads to a major loss of revenue in leading palm oil producing countries in Southeast Asia. Here in this study, we assess the morphological and biochemical changes in Ganoderma disease infected oil palm seedling roots in both resistant and susceptible progenies. Rubber woodblocks fully colonized by G. boninense were applied as a source of inoculum to artificially infect the roots of resistant and susceptible oil palm progenies...

The intestinal mucosal barriers play essential roles not only in the digestion and absorption of nutrients, but also the innate defense against most intestinal pathogens. In the present study, polysaccharide from the mycelia of Ganoderma lucidum was given via oral administration to rats (100mg/kg body weight, 21days) to investigate its effects on intestinal barrier functions, including the mechanical barrier, immunological barrier and biological barrier function. It was found that the polysaccharide administration could significantly up-regulate the expression of occludin, nuclear factor-κB p65 (NF-κB p65) and secretory immunoglobulin A (SIgA) in ileum, markedly improve the levels of interferon-γ (IFN-γ), interleukin-2 (IL-2), and IL-4, and decrease the level of diamine oxidase (DAO) in serum...

Polysaccharides from different types of natural herbs have not been compared with each other to determine their differential potencies on innate immune response, such as maturation of dendritic cells (DC). In addition, the role of endocytosis of polysaccharides in DC maturation has not been explored previously. Polysaccharides isolated from Astragalus membranaceus (APS), Ganoderma lucidum (GLP) and Radix ophiopogonis (OGP) were characterized and applied in bone marrow derived DC. Compared to immature DC, three polysaccharides with immunoactivities showed elongated dendrites, decreased phagocytic abilities, phenotypic changes (CD40/MHCII/CD80/CD86) and increased level of nitric oxide (NO) in a dose dependent manner...

A semi-covalent imprinting strategy has been developed for the synthesis of molecularly-imprinted polymers specific for the fungal sterol, ergosterol, a biological precursor of vitamin D2. This imprinting approach involved a novel post-synthesis cleavable monomer-template composite, namely ergosteryl methacrylate, and resulted in the formation of an imprinted polymer that selectively and efficiently recognized ergosterol through non-covalent interactions. The derived molecularly-imprinted polymer and the corresponding non-imprinted polymer were systematically evaluated for their selectivity towards ergosterol via static and dynamic binding studies using various ergosteryl esters (e...
