Ergosterol peroxide inhibits ovarian cancer cell growth through multiple pathways
Ergosterol peroxide (EP), a sterol derived from medicinal mushrooms, has been reported to exert antitumor activity in several tumor types. However, the role of EP toward ovarian cancer cells has not been investigated. In this study, we analyzed the cytotoxicity of EP in various cell lines representing high-grade serous ovarian cancer and low-grade serous ovarian cancer, respectively. Although E...
متن کاملRelationship of Soil Ergosterol Concentration and Fungal Biomass
We studied the relationship between amounts of fungi and ergosterol in soil to further evaluate the use of ergosterol as an indicator of soil fungal biomass. Soils from seven sites in central Iowa were analyzed for soil ergosterol content, total fungal hyphal length (living and non-living, using calcofluor as stain), and living fungal hyphal length (using fluorescein diacetate as stain) to: 1) ...
متن کاملErgosterol as a Biochemical Indicator of Fungal Infection in Spruce and Fir Needles from Different Sources
Different fungi are discussed to play a certain role in recent spruce decline in addition to different abiotic factors such as S 0 2, photooxidants (ozone) or unfavourable climatic conditions. Thus, ergosterol as a specific fungal sterol was used as a biochemical indicator for fungal infection in differently damaged spruce and fir needles. With its aid it could be demonstrated that the importan...
متن کاملGrading of Fermented and Dried Cocoa Beans Using Fungal Contamination, Ergosterol Index and Ochratoxin a Production
Sixty four samples of cocoa beans replicated in quadruplicates were collected from five warehouses from southwest Nigeria and examined for fungal loads, ergosterol and ochratoxin A The levels of all the variables obtained were further used as indices for cocoa grading into food quality, FoQ (erg < 5 mg/kg; OTA < 1 µg/kg), feed quality, FeQ (erg = 5~10 mg/kg; OTA in the range of 1.1~3.11 µg/kg),...
متن کاملEvaluating the Use of Ergosterol as a Bioindicator for Assessing Fungal Response to Water Quality
This study investigated the in situ production of fungal biomass on presterilized woody substrates submerged in natural estuarine and freshwater bodies enriched with nitrogen and phosphoruscontaining chemical compounds. Results suggest that the membrane-bound sterol ergosterol may hold significant promise as an quantitative indicator of fungal response to water quality. We suggest that realisti...
