Introduction: Many patients with breast cancer fail to respond to conventional chemotherapeutic agents; these agents are also associated with numerous adverse events and toxicities. These concerns have led to the ongoing search for natural ingredients with antitumor effects. As such, the aim of this study was to explore the anti-cancer properties of an ethanolic extract of propolis (EEP), a natural product derived from the stingless bee, from Tetragonula laeviceps. Methods: Bioactive components of EEP were identified by gas chromatography{\textendash}mass spectrometry (GC{\textendash}MS) and antioxidant capacity was tested by 2.2-diphenyl1-picrylhydrazyl (DPPH) analysis. Selective cytotoxic actions of EEP on both MCF-7 and Vero cells were then evaluated using the MTT assay. Polyphenols were identified as the major components of EEP from T. laeviceps. Results: our results indicated that EEP was selectively toxic for human MCF-7 breast cancer cells and had only limited impact on African Green Monkey kidney Vero cells. Conclusion: EEP from T. laeviceps has bioactive components that may selectively inhibit the proliferation of cancer cells. As such, EEP may be useful source material to be used for the development of novel anti-cancer agents.

Introduction: Ovarian cancer is a major cause of cancer-related death among women. The growth, persistence, and cancer metastasis are causes of poor prognosis and high mortality rate. Honokiol and magnolol are derivative compounds extracted from the root and stem bark of Magnolia officinalis. Many studies have reported that honokiol and magnolol have anti-tumour effects on various types of cancer. The present study investigates the anti-tumour effect of these compounds on human ovarian cancer. Methods: Ovarian cancer cell lines, SKOV3 and ES-2 cells were tested with honokiol and magnolol to determine their responses including the cytotoxicity, cell proliferation, induction of cell apoptosis and metastasis ability. Result: The results indicate that low concentrations of honokiol and magnolol suppressed the proliferation of ovarian cancer cells through induction of cell cycle arrest at G0/G1 and down-regulation of the cyclin D1 protein. These compounds also exhibited an anti-metastatic ability mediated by inhibiting migration, adhesion, and MMP activities. Additionally, high concentrations of honokiol and magnolol could activate cell death associated with the apoptosis signalling pathway, either along an intrinsic or extrinsic pathway. Conclusion: The data provides evidence that honokiol and magnolol have potential anti-tumour properties and minimal toxicity on normal cells, and could therefore be applied in the treatment of ovarian cancer.

The endothelial progenitor cell (EPCs) proliferation capability is reduced in the patient with stable coronary artery disease (SCAD). Garlic (Allium sativum), purple sweet potato (Ipomoea batatas), and vitamin C are proven antioxidant which potentially improve EPCs proliferation ability. Objective: To investigate the effect of garlic (Allium sativum), purple sweet potato (Ipomoea batatas), and vitamin C in EPCs proliferation from CAD patients and identify the involvement of Extracellular-Signal Regulated Kinase (ERK) Signalling Pathway. Material and Method: Mononuclear cells were isolated from SCAD patients and cultivated with colony-forming unit (CFU)-Hill medium and divided into untreated (control), garlic extract (10 mcg/ml and 100 mcg/ml), purple sweet potato extract (1 mcg/ml and 25 μg/ml), and vitamin C (10 μg/ml and 250 μg/ml). EPCs proliferation was measured using the MTT Assay. Results: This research shows that EPCs proliferation was increased in the treatment with garlic extract at 10 mcg/ml and 100 mcg/ml dose (0.267 {\textpm} 0,003 and 0.391 {\textpm} 0.008 ; p \< 0.05), purple sweet potato extract at 1 mcg/ml and 25 μg/ml dose (0.250 {\textpm} 0.005 and 0.3562 {\textpm} 0.023 ; p \< 0.001), and vitamin C at 10 μg/ml and 250 μg/ml dose (0.259 {\textpm} 0.016 and 0.306 {\textpm} 0.022 ; p \< 0.001). Increased ERK expression was found in the treatment with garlic extract, purple sweet potato extract and vitamin C. Conclusion: Garlic extract, purple sweet potato extract, and vitamin C can increase EPC proliferation through the ERK signaling pathway.
