Background: Mitochondrial manganese superoxide dismutase (MnSOD) converts superoxide anion into H2O2, which is neutralized sequentially by either catalase (CAT) or glutathione peroxidase 1 (Gpx 1) into water or converted into highly reactive hypochlorous acid by myeloperoxidase (MPO). We hypothesize that gene variants for these enzymes might be associated with the risk of breast cancer in non-smoking, non-alcohol-consuming women. Methods: Genotypes of oxidative stress-related enzymes (MnSOD1183T>C, MPO-463G>A, GPx1Pro198Leu and CAT-262C>T) were analysed in 260 non-smoking and non-alcohol-consuming female patients with breast cancer and 224 habit-matched controls. Results: Subjects with the MnSOD1183T>C C carrier or those with the GPx1Pro198Leu CT genotype had significantly decreased age-adjusted risks (odds ratio [OR]: 0.56 and 0.16 with 95% confidence intervals [95% CI]: 0.38-0.83 and 0.08-0.29, respectively) for breast cancer. Certain combined genotypes of the polymorphisms also significantly modulated the age-adjusted risk. Conclusions: We conclude that oxidative stress-related enzyme genetic variants, especially GPx1Pro198Leu CT, modify the risk of breast cancer development in non-smoking and non-alcohol-consuming women. The role of unidentified environmental factors predisposing to breast cancer development through an oxidative stress mechanism merits further investigation.

Impacts of Oxidative Stress and PI3K/AKT/mTOR on Metabolism and the Future Direction of Investigating Fucoidan-Modulated Metabolism

Jun-Ping Shiau, Ya-Ting Chuang, Yuan-Bin Cheng, Jen-Yang Tang, Ming-Feng Hou, Ching-Yu Yen, Hsueh-Wei Chang

Summary: The critical factors for regulating cancer metabolism are oxidative stress and PI3K/AKT/mTOR. However, their effects on various metabolic mechanisms are complex. Natural product fucoidan has the potential to modulate oxidative stress and PI3K/AKT/mTOR and has anticancer properties. This review summarizes the roles of oxidative stress and PI3K/AKT/mTOR in metabolism and explores the potential application of fucoidan in metabolic regulation.

Fucoidan/UVC Combined Treatment Exerts Preferential Antiproliferation in Oral Cancer Cells but Not Normal Cells

Ya-Ting Chuang, Jun-Ping Shiau, Ching-Yu Yen, Ming-Feng Hou, Jiiang-Huei Jeng, Jen-Yang Tang, Hsueh-Wei Chang

Summary: Combined treatment is a promising strategy for cancer therapy, but it may have adverse effects on normal cells. This study found that fucoidan (FN), a safe food ingredient derived from brown algae, has preferential antiproliferation effects on oral cancer cells. When combined with ultraviolet C (UVC) irradiation, FN effectively reduced the viability of oral cancer cells and induced higher levels of apoptosis, oxidative stress, and DNA damage compared to single treatments. This suggests that UVC/FN treatment has potential for targeted and synergistic antiproliferation in oral cancer therapy.

Antiproliferation Effects of Marine-Sponge-Derived Methanol Extract of Theonella swinhoei in Oral Cancer Cells In Vitro

Jun-Ping Shiau, Ya-Ting Chuang, Jen-Yang Tang, Shu-Rong Chen, Ming-Feng Hou, Jiiang-Huei Jeng, Yuan-Bin Cheng, Hsueh-Wei Chang

Summary: This study aimed to evaluate the antiproliferative effects of methanol extract of T. swinhoei (METS) on oral cancer cells and compare its detailed responses to normal cells. The results showed that METS effectively inhibited the proliferation of oral cancer cells while not affecting normal cell viability, suggesting a preferential antiproliferative function. METS induced apoptosis, cellular and mitochondrial oxidative stress, and DNA damage in oral cancer cells, which could be reversed by an oxidative stress inhibitor. Additionally, METS activated both extrinsic and intrinsic caspases.

The Impact of Oxidative Stress and AKT Pathway on Cancer Cell Functions and Its Application to Natural Products

Jun-Ping Shiau, Ya-Ting Chuang, Jen-Yang Tang, Kun-Han Yang, Fang-Rong Chang, Ming-Feng Hou, Ching-Yu Yen, Hsueh-Wei Chang

Summary: Oxidative stress and AKT pathway play crucial roles in regulating various cell functions in cancer cells. Natural products have the potential to modulate oxidative stress and AKT for anticancer effects. However, the underlying mechanisms of how they regulate cell functions, particularly the contribution of AKT downstream effectors, are not well understood. This review discusses the roles of oxidative stress and AKT pathway in ten cell functions and highlights the potential of natural products in regulating these functions, with a focus on AKT effectors that have been rarely reported.

Huei-Yi Tsai, Tsung-Yu Tsai, Chia-Hui Wu, Wei-Shiuan Chung, Jo-Ching Wang, Jui-Sheng Hsu, Ming-Feng Hou, Ming-Chung Chou

Summary: This study explored the potential of a machine learning model integrating clinical and CT-based radiomics features to predict the pathologic complete response (pCR) to neoadjuvant systemic therapy (NST) in breast cancer patients. The results showed that integrating clinical data and radiomics features significantly improved model performance, achieving an accuracy of 0.87, compared to clinical (0.69) and radiomics (0.78) models. Furthermore, the use of more high-order textural features with high reproducibility further enhanced the model's performance. In conclusion, the integration of clinical and CT-based radiomics features was found to be helpful in predicting pCR to NST in breast cancer patients.

Summary: This study found that 3HDT has an antiproliferative effect on triple-negative breast cancer cells, while having less impact on normal cells. Through various tests, it was found that 3HDT mainly acts on TNBC cells through oxidative stress and causes DNA damage. Therefore, 3HDT is an effective drug with selective antiproliferative and therapeutic effects on TNBC cells.
