Possible Chemosensitizing and Potent Anticancer Effects of D-Fraction in Combination with Vitamin C on Three Prevalent Urologic Cancer Cells

引用

Journal of Cancer Therapy 2014年第14期5卷 1402-1411页

作者： Drew Freilich Eric Moskowitz Nicholas Feuer Muhammad Choudhury john phillips Sensuke Konno Department of Urology New York Medical College Valhalla USA

Chemotherapy is currently one of the most common therapeutic options for cancer patients despite the poor efficacy with considerable side effects. We then examined if D-fraction (DF), a bioactive mushroom extract, could potentiate (poor) anticancer effects of those drugs?in vitro. Three urologic cancers, prostate, bladder, and kidney cancers, were tested with various chemotherapeutic drugs and their combinations with DF. Compared to individual drugs alone, combinations of drugs and DF have improved anticancer activity, resulting in the significant (P < 0.05) cell viability reduction in all three cancer cells. As vitamin C (VC) has been postulated to potentiate the bioactivity of DF, this possibility was also examined. The specific combination of DF (300 μg/ml) and VC (200 μM) indeed led to the drastic (≥90%) viability reductions in all three cancer cells. To have a better understanding of such a profound viability reduction, the effect of DF/VC combination on cell cycle was examined next. Cell cycle analysis indicated that this combination induced a G1cell cycle arrest, which was also confirmed by the down-regulation of specific cell cycle regulators (CDK2, CDK4, and cyclin D1) detected on western blots. Moreover, it was crucial to address if the DF/VC-induced viability reduction could be also linked to apoptosis. Western blot analysis revealed that anti-apoptotic bcl-2 was down-regulated while pro-apoptotic Bax was up-regulated with DF/VC combination in all cancer cells, indicating induction of apoptosis. Therefore, the DF/VC combination could ultimately induce apoptosis, accounting for the severe cell viability reduction. In conclusion, DF appears to be a promising agent with chemosensitizing effect, enhancing the efficacy of chemotherapeutic drugs, and its combination with VC exhibits a potent anticancer effect, which is far superior to any combinations of drugs and DF tested in three prevalent urologic cancer cells.

Observations of the Germination Behavior of <i>Tilletia indica</i>Teliospores on the Soil Surface under Varying Simulated Environmental Conditions

引用

American Journal of Plant Sciences 2017年第11期8卷 2878-2897页

作者： Gary L. Peterson Dana K. Berner john G. phillips USDA ARS Foreign Disease-Weed Science Research UnitFort Detrick USA USDA-ARS-North Atlantic Area Wyndmoor USA

A series of replicated growth chamber studies were conducted to determine the effects of soil type and simulated European temperature conditions from fall planting to anthesis in Hungary, United Kingdom, Italy and Norway on the initiation of Tilletia indica teliospore germination on the soil surface. A concurrent study examined effects on teliospore germination of a simulated temperature profile for Ciudad Obregon, Mexico, where Karnal bunt is known to occur. Three soil moisture treatments were tested;40.5% water holding capacity (WHC), 16.2% WHC and weekly fluctuation of soil WHC. Results suggest that soil type would not have a significant effect on germination during the cropping season. Under all conditions tested, some portion of the teliospore population remained dormant but viable throughout the entire season. In comparing Mexican and Hungarian temperature profiles, highest soil surface germination for the Hungarian profile was at 40.5% WHC during the first 30 days of the simulation (30 days after planting date). The highest germination for the Mexican profile was at the 16.2% WHC during the last 30 days of the study (time of anthesis).
