Traditional use of the tiger milk medicinal mushroom, Lignosus rhinocerus, to treat various illnesses has been recorded for > 4 centuries. Successful cultivation of L. rhinocerus using proprietary solid-state fermentation (SSF) technology by LiGNO Biotech has enabled large-scale production of L.

Antioxidant and Cytotoxic Effects and Identification of Bioactive Proteins Using Shotgun Proteomic Analysis.

Research Background: a highly valued medicinal fungus, is close to extinction due to overexploitation. Successful cultivation of fruiting body (OCS02®) shows that the cultivar has a promising nutritional value and numerous bioactive compounds. Antioxidant and antiproliferative properties and biologically active proteins of the OCS02® are investigated for possible development into nutraceuticals.

Proteins from with selective apoptotic cytotoxicity towards MCF7 cell line and suppresses MCF7-xenograft tumor growth.

Background: , a recently discovered species of the unique family, has been traditionally used by the indigenous communities in Peninsular Malaysia to treat various ailments and as an alternative medicine for cancer treatment. The cultivar sclerotia (Ligno TG-K) was found to contain numerous bioactive compounds with beneficial biomedicinal properties and the sclerotial extract exhibited potent antioxidant activity. However, the anticancer property of the Ligno TG-K including in vitro and in vivo antitumor effects as well as its anticancer active compounds and the mechanisms has yet to be investigated.

Acute Toxicity Study and the In Vitro Cytotoxicity of a Black Lingzhi Medicinal Mushroom, Amauroderma rugosum (Agaricomycetes), from Malaysia.

Amauroderma rugosum is a wild medicinal mushroom also known as budak cendawan sawan. Members of the indigenous Malaysian Temuan community wear the fresh stipes as a necklace to prevent epileptic seizure and unremitting crying by babies. In our previous studies, A.

Heterologous expression of cytotoxic sesquiterpenoids from the medicinal mushroom Lignosus rhinocerotis in yeast.

Background: Genome mining facilitated by heterologous systems is an emerging approach to access the chemical diversity encoded in basidiomycete genomes. In this study, three sesquiterpene synthase genes, GME3634, GME3638, and GME9210, which were highly expressed in the sclerotium of the medicinal mushroom Lignosus rhinocerotis, were cloned and heterologously expressed in a yeast system.
