Abstract
Objective: This study investigated the potential anticancer properties of Myo-inositol on the DU-145 prostate cancer cell line.
Methods: The DU-145 cells have been treated to different doses of Myo-inositol in order to ascertain the half-maximal inhibitory concentration (IC50) using the trypan blue exclusion assay. The impact of Myo-inositol on proteomic profiles was evaluated using 2D gel electrophoresis and liquid chromatography-mass spectrometry (LC-MS).
Results: Myo-inositol significantly reduced DU-145 cell viability with an IC50 of 0.06 mg/ml (p<0.05). Proteomic analysis highlighted marked differences in protein expression between treated and untreated cells, particularly in proteins related to cytoskeletal regulation, apoptosis, and stress response. LC-MS further identified significant alterations in protein profiles, with suppression of proteins like Annexin A2 and Cofilin-1-A in controls, and upregulation of proteins such as Rho GTPase-activating protein, Apoptotic protease-activating factor 1 (APAF1), and TNF receptor-associated factor 2 (TRAF2) in treated samples (p<0.001), indicating modulation of key signaling pathways involved in tumor suppression and oncogenesis.
Conclusion: Myo-inositol exhibits anticancer properties in prostate cancer cells by impacting cell viability and altering protein expression. While promising as an adjunctive treatment, further studies are needed to understand its mechanisms and potential in combination therapies for managing CRPC.
期刊介绍：
Cancer is a very complex disease. While many aspects of carcinoge-nesis and oncogenesis are known, cancer control and prevention at the community level is however still in its infancy. Much more work needs to be done and many more steps need to be taken before effective strategies are developed. The multidisciplinary approaches and efforts to understand and control cancer in an effective and efficient manner, require highly trained scientists in all branches of the cancer sciences, from cellular and molecular aspects to patient care and palliation.
The Asia Pacific Organization for Cancer Prevention (APOCP) and its official publication, the Asia Pacific Journal of Cancer Prevention (APJCP), have served the community of cancer scientists very well and intends to continue to serve in this capacity to the best of its abilities. One of the objectives of the APOCP is to provide all relevant and current scientific information on the whole spectrum of cancer sciences. They aim to do this by providing a forum for communication and propagation of original and innovative research findings that have relevance to understanding the etiology, progression, treatment, and survival of patients, through their journal. The APJCP with its distinguished, diverse, and Asia-wide team of editors, reviewers, and readers, ensure the highest standards of research communication within the cancer sciences community across Asia as well as globally.
The APJCP publishes original research results under the following categories:
-Epidemiology, detection and screening.
-Cellular research and bio-markers.
-Identification of bio-targets and agents with novel mechanisms of action.
-Optimal clinical use of existing anti-cancer agents, including combination therapies.
-Radiation and surgery.
-Palliative care.
-Patient adherence, quality of life, satisfaction.
-Health economic evaluations.
