Renal protective effects of helix B surface polypeptide in rats with puromycin aminonucleoside nephropathy.

Background: Recent studies have reported that helix B surface polypeptide (HBSP), an erythropoietin derivative, exhibits strong tissue protective effects, independent of erythropoietic effects, in a renal ischemia-reperfusion (IR) injury model. Meanwhile, the transforming growth factor-β (TGF-β) superfamily member glial cell line-derived neurotrophic factor (GDNF) demonstrated protective effect on podocytes . Using a rat puromycin aminonucleoside nephropathy (PAN) model, this study observed the renal protective effect of HBSP and investigated its renal protective effect on podocytes and mechanism related to GDNF.

Optimisation of hypocrellin production in -like fungi via genetic modification involving a transcription factor gene and a putative monooxygenase gene.

-like fungi, which are rare parasitic fungi found around bamboo, play an important role in traditional medicine. Their main active component, hypocrellin, is widely used in medicine, food, and cosmetics. By comparing strains with different hypocrellin yields, we identified a transcription factor () in the hypocrellin biosynthesis pathway.

Phylogenetic Position of -Like Endophytes on Bamboos and the Diverse Biosynthesis of Hypocrellin and Hypocrellin Derivatives.

The main active ingredients of the fruiting bodies of and are Hypocrellins, belonging perylenequinones with potential photodynamic activity against cancer and microbial diseases. However, the strains of and do not produce hypocrellins in culture, so resource exploitation of natural products was seriously restricted. In this study, a series of novel -like fungal endophyte strains, with varying sporulation ability and synthesizing diverse secondary metabolites, was isolated from different bamboos.

Global identification of alternative splicing in Shiraia bambusicola and analysis of its regulation in hypocrellin biosynthesis.

Hypocrellins, as natural pigments from Shiraia bambusicola, have extensive applications in the agricultural, cosmetic, food, and feed industries, and play a vital role in photodynamic therapy for anticancer and antiviral treatments. However, environmental stresses are always the bottlenecks for increasing hypocrellin yield during the process of fermentation. Pre-mRNA alternative splicing (AS) is an essential mechanism in the defense of abiotic stresses in the animal and plant kingdom, but is seldom involved in fungi.

Antioxidant and antimicrobial activities of various extracts from Engleromyces sinensis fruiting body.

Engleromyces sinensis, as rare macro-ascomycetes and traditional ethnomedicine in the southeast part of China, have been applied in anti-infection, anti-inflammatory and anti-tumor for a long time. In this study, the antioxidant activities of ethyl acetate crude extract (EACE), acetone crude extract (ACE), 95% ethanol crude extract (ECE), methanol crude extract (MCE) and water crude extract (WCE) from E. sinensis fruiting body were investigated using conventional antioxidant assays in vitro for the first time.

Diversity and antimicrobial activity of culturable fungi from fishscale bamboo (Phyllostachys heteroclada) in China.

An important and useful bamboo species, fishscale bamboo (Phyllostachys heteroclada Oliver), is broadly distributed in Southeast China and has multiple purposes, including uses in cuisine, weaving, Chinese medicine and ecological protection. However, no previous studies have focused on the endophytes of this plant. In our article, a total of 127 fungal strains were first isolated from the healthy branches and leaves of common P.

Selection of reference genes from Shiraia bambusicola for RT-qPCR analysis under different culturing conditions.

Stable reference genes are necessary to analyse quantitative real-time reverse transcription PCR (qRT-PCR) data and determine the reliability of the final results. For further studies of the valuable fungus Shiraia bambusicola, the identification of suitable reference genes has become increasingly urgent. In this study, three conventional reference genes and nine novel candidates were evaluated under different light conditions (all-dark, all-light and 12-h light/dark) and in different media (rice medium, PD medium, and Czapek-Dox medium).

High-efficiency biosynthesis of hypocrellin A in Shiraia sp. using gamma-ray mutagenesis.

Hypocrellin A (HA), well known as one of the best natural pigments and bioactive agent to treat skin diseases, is further anticipated to play a vital role in photodynamic therapy (PDT) in anticancer and antiviral treatments. In this study, an HA-producing strain ZZZ816 (Shiraia sp.) was isolated from the moso bamboo (Phyllostachys edulis) seeds, and gamma irradiation was used to mutagenize spores of the original strain.

Identification and Evaluation of Reliable Reference Genes in the Medicinal Fungus Shiraia bambusicola.

The stability of reference genes plays a vital role in real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis, which is generally regarded as a convenient and sensitive tool for the analysis of gene expression. A well-known medicinal fungus, Shiraia bambusicola, has great potential in the pharmaceutical, agricultural and food industries, but its suitable reference genes have not yet been determined. In the present study, 11 candidate reference genes in S.

Characterization and phylogenetic analysis of the mitochondrial genome of Shiraia bambusicola reveals special features in the order of pleosporales.

Shiraia bambusicola P. Henn. is a pathogenic fungus of bamboo, and its fruiting bodies are regarded as folk medicine.

Diversity and antimicrobial activity of culturable endophytic fungi isolated from moso bamboo seeds.

Bamboos, regarded as therapeutic agents in ethnomedicine, have been used to inhibit inflammation and enhance natural immunity for a long time in Asia, and there are many bamboo associated fungi with medical and edible value. In the present study, a total of 350 fungal strains were isolated from the uncommon moso bamboo (Phyllostachys edulis) seeds for the first time. The molecular diversity of these endophytic fungi was investigated and bioactive compound producers were screened for the first time.
