Potential Anticancer Effect of Bioactive Extract of Monk Fruit (Siraitia grosvenori) on Human Prostate and Bladder Cancer Cells

Journal of Cancer Therapy 2023年第5期14卷 211-224页

Prostate and bladder cancers are the two prevalent urological cancers, and several therapeutic options are currently available but the outcomes have not been satisfactory. To find the better therapeutic option, we investigated if the bioactive extracts of monk fruit, mogrosides, with potential anticancer activity might have anticancer effect against prostate and bladder cancer cells. Four of commercial products made of mogrosides known as Lakantoò (LKT) products, LK1, LK2, LLE, and MOG, were then tested. A dose-dependent study at given concentrations of four products showed that LK1 and LK2 had little effects, while LLE and MOG showed a significant cell viability reduction in both PC-3 and T24 cells. To explore the anticancer mechanism of such products, cell cycle analysis was first performed. Such analysis revealed that LLE and MOG, not LK1 and LK2, led to a G1 cell cycle arrest. Potential induction of endoplasmic reticulum (ER) stress was next examined because it is known to be linked to a cell cycle arrest. The three key regulators involved in ER stress were all up-regulated with LLE or MOG, indicating induction of ER stress. As ER stress is also known to induce apoptosis, this possibility was tested. The two apoptotic regulators were modulated in a specific manner with LLE or MOG, indicating induction of apoptosis. Lastly, to validate anticancer effect of LLE or MOG, anticancer effect of four chemotherapeutic drugs was also assessed in comparison with that of LLE/MOG. None of drugs had any effects but two products showed significant anticancer effect. In conclusion, two monk fruit products, LLE and MOG, demonstrated anticancer activity against PC-3 and T24 cells, significantly reducing cell viability and ultimately inducing apoptosis. Therefore, these two LKT products with few side effects may have clinical implications in the treatment of urological cancers.

Saturated anisotropic hydraulic conductivity of a compacted lateritic soil

引用

Journal of Rock Mechanics and Geotechnical Engineering 2018年第5期10卷 986-991页

作者： Roberto Aguiar dos Santos Edmundo rogerio Esquivel Varzea Grande Institute of Engineering Federal University of Mato Grosso Cuiaba Mato Grosso Brazil Sao Carlos School of Engineering University of Sao Paulo Sao Carlos Sao Paulo Brazil

This study focuses on the saturated anisotropic hydraulic conductivity of a compacted lateritic clayey sandy soil. The effects of the molding water content and the confining stress on the anisotropic hydraulic conductivity are investigated. The hydraulic conductivity is measured with a flexible-wall permeameter. Samples are dynamically compacted into the three compaction states of a standard Proctor compaction curve： the dry branch, optimum water content and wet branch. Depending on the molding water content and confining stress, the hydraulic conductivity may increase or decrease. In addition, the results indicate that, when the samples are compacted to the optimum water content, lower hydraulic conductivity is obtained, except at a confining stress equal to 50 kPa. The increase of the confining stress decreases the hydraulic conductivity for each of the evaluated compaction states. In the wet branch, horizontal hy- draulic conductivity is about 8 times higher than the vertical value. The anisotropic hydraulic conduc- tivities of the dry and wet branches decrease when the confining stress increases, and the opposite is observed in the optimum water content state.
