Pleurotus Ostreatus

Pleurotus Ostreatus is commonly known as the Oyster Mushroom and is named because of the appearance with the shell of oysters.

These mushrooms are considered a superfood and can be found at nearly every part of the world. These are one of the easiest mushrooms to grow and find in the wild. While they grow in mostly every climate ranging from temperate to tropical regions.

These mushrooms have been enjoyed for less than a 100 years and studies that are currently conducted are just beginning to show the amazing benefits this mushroom contains.

Anti-Tumor - Water-soluble proteoglycan fractions from P. ostreatus mycelia were purified by alcohol-precipitation, ion exchange and followed by gel permeation (Sephadex G-100) chromatography.

Three neutral fractions were found, which had polysaccharide to protein ratios 14.2, 26.4 and 18.3, respectively.

These fractions were tested for in vitro and in vivo immunomodulatory and anticancer effects on Sarcoma-180-bearing mouse model.

The three neutral proteoglycans derived from the mushroom (P. ostreatus) mycelia could be used as immunomodulators and anti cancer agents.

Apoptosis - Anti-proliferative and pro-apoptotic activities of fractions of Pleurotus ostreatus were examined using HT-29 colon cancer cells in vitro.

A hot-water-soluble fraction of the mycelium of the liquid cultured mushroom was partially isolated and chemically characterized as a low-molecular-weight α-glucan.

We describe a newly identified low-molecular-weight α-glucan with promising anti-tumorigenic properties, and demonstrate its direct effect on colon cancer cell proliferation via induction of programmed cell death.

The role of apoptosis, proliferative cell nuclear antigen (PCNA) and p53 protein in the preventive effects of dietary fiber treated with the fungus Pleurotus ostreatus on rat-colon tumorigenesis was studied.

The fungus treated corn-cob significantly decreased tumor incidence (to 26%) as compared to 44% and 57% in the other dietary groups.

Incubation of corncob with the fungus Pleurotus os, increased the dietary fiber content up to 78%. Thus corncob inhibits colon cancer development, and, therefore, may considered of potential use to the public.

Calvatia lilacina (CL), Pleurotus ostreatus (PO) and Volvariella volvacea (VV) are widely distributed worldwide and commonly eaten as mushroom
