We investigated the potential benefits of Myo-inositol, a naturally occurring sugar alcohol, on DU-145 prostate cancer cells. By treating these cancer cells with various doses of Myo-inositol, we determined its half-maximal inhibitory concentration (IC50) using a simple method that measures cell viability.
Our findings revealed that Myo-inositol significantly decreased the viability of DU-145 cells, showing an IC50 of 0.06 mg/ml. This suggests that Myo-inositol may effectively inhibit cancer cell growth.
Furthermore, we performed a detailed proteomic analysis using advanced techniques to explore how Myo-inositol changes protein expression. We found notable differences in protein levels between treated and untreated cells, particularly in areas linked to key cellular functions like cytoskeletal regulation, apoptosis (cell death), and stress responses. For instance, certain proteins tied to tumor suppression were upregulated in response to Myo-inositol treatment.
Overall, these observations highlight Myo-inositol's potential as a therapeutic option. However, further studies are necessary to unravel the underlying mechanisms and assess its effectiveness in combination with other treatments for managing prostate cancer, especially castration-resistant prostate cancer (CRPC).

We investigated how isogarcinol (ISO) influences breast cancer cells and what mechanisms are at play. Through lab tests, we found that ISO at 13 μM effectively lowered cell growth and movement. In living subjects, doses of 5 to 15 mg/kg showed a significant reduction in tumor activity.
We observed that ISO achieves its tumor-suppressing effects by lowering the levels of a protein called methionyl-tRNA synthetase (MARS) and deactivating key pathways involved in cancer progression. These findings suggest ISO could be a valuable addition to breast cancer treatment strategies.

Vitamin E Succinate enhances autophagy[The role of endoplasmic reticulum IP(3)R calcium channel in vitamin E succinate induced autophagy of human gastric cancer cell].
High relevance to gastric cancer treatment
We examined how vitamin E succinate (VES) affects autophagy in human gastric cancer cells by activating a calcium signaling pathway. Our study involved cultured gastric cancer cell lines treated with various doses of VES. We noted that VES significantly reduced cell proliferation and enhanced the formation of autophagosomes, indicating increased autophagy.
However, when we inhibited the calcium channel involved, the positive effects of VES diminished, suggesting the importance of this pathway in its action. Overall, while VES shows promise in promoting autophagy, further research is needed to understand its full potential in cancer treatment.
