Magnesium from Deep Seawater as a Potentially Effective Natural Product against Insulin Resistance: A Randomized Trial.

: Deep seawater has been shown to restore pancreatic function in obese diabetic mice and considerably improve the homeostatic model assessment for insulin resistance, total cholesterol, and low-density lipoprotein cholesterol concentrations in patients with impaired fasting glucose or glucose tolerance. In this study, the effect of 12-week daily consumption of magnesium (Mg)-containing deep seawater mineral extracts on blood glucose concentration and insulin metabolism-associated indicators was investigated in patients with impaired glucose tolerance. : In this 12-week randomized, double-blind trial, patients ( = 37) with impaired glucose tolerance consumed deep seawater mineral extracts.

Natural Magnesium-Enriched Deep-Sea Water Improves Insulin Resistance and the Lipid Profile of Prediabetic Adults: A Randomized, Double-Blinded Crossover Trial.

Previous in vitro and in vivo studies have shown that the antidiabetic effect of balanced deep-sea water (BDSW) works through the suppression of hyperglycemia and improvement of glucose tolerance. Based on these promising results, we conducted an eight week randomized, double-blinded crossover trial of the effects of BDSW in prediabetic adults. The subjects consumed 440 mL of BDSW (hardness 4000) per day, and maintained an otherwise normal lifestyle and diet throughout.

Mineral-Enriched Deep-Sea Water Modulates Lactate Metabolism via PGC-1α-Mediated Metabolic Reprogramming.

Metabolic disorders such as diabetes and obesity are serious global health issues. These diseases are accelerated by mineral deficiencies, emphasizing the importance of addressing these deficiencies in disease management plans. Lactate metabolism is fundamentally linked to glucose metabolism, and several clinical studies have reported that blood lactate levels are higher in obese and diabetic patients than in healthy subjects.

Effects of proton beam irradiation on mitochondrial biogenesis in a human colorectal adenocarcinoma cell line.

Proton beam therapy has recently been used to improve local control of tumor growth and reduce side-effects by decreasing the global dose to normal tissue. However, the regulatory mechanisms underlying the physiological role of proton beam radiation are not well understood, and many studies are still being conducted regarding these mechanisms. To determine the effects of proton beams on mitochondrial biogenesis, we investigated: mitochondrial DNA (mtDNA) mass; the gene expression of mitochondrial transcription factors, functional regulators, and dynamic-related regulators; and the phosphorylation of the signaling molecules that participate in mitochondrial biogenesis.

Magnesium and calcium-enriched deep-sea water promotes mitochondrial biogenesis by AMPK-activated signals pathway in 3T3-L1 preadipocytes.

Recent studies showed that deficiencies of essential minerals including Mg, Ca, and K, and trace minerals including Se, Zn, and V, have implications for the development, prevention, and treatment of several chronic diseases including obesity and type 2 diabetes. Our previous studies revealed that balanced deep-sea water (BDSW), which is composed of desalinated water enriched with Mg and Ca, has potential as a treatment for diabetes and obesity. In this study, to determine whether BDSW regulates mitochondrial biogenesis and function, we investigated its effects on mitochondrial DNA (mtDNA) content, mitochondrial enzyme activity, expression of key transcription factors and mitochondria-specific genes, phosphorylation of signaling molecules associated with mitochondrial biogenesis, and mitochondrial function in 3T3-L1 preadipocytes.

Stimulatory Effects of Balanced Deep Sea Water on Mitochondrial Biogenesis and Function.

The worldwide prevalence of metabolic diseases, including obesity and diabetes, is increasing. Mitochondrial dysfunction is recognized as a core feature of these diseases. Emerging evidence also suggests that defects in mitochondrial biogenesis, number, morphology, fusion, and fission, contribute to the development and progression of metabolic diseases.

Inhibitory effects of proton beam irradiation on integrin expression and signaling pathway in human colon carcinoma HT29 cells.

Proton radiotherapy has been established as a highly effective modality used in the local control of tumor growth. Although proton radiotherapy is used worldwide to treat several types of cancer clinically with great success due to superior targeting and energy deposition, the detailed regulatory mechanisms underlying the functions of proton radiation are not yet well understood. Accordingly, in the present study, to assess the effects of proton beam on integrin-mediated signaling pathways, we investigated the expression of integrins related to tumor progression and integrin trafficking, and key molecules related to cell adhesion, as well as examining phosphorylation of signaling molecules involved in integrin-mediated signaling pathways.

Evaluation of cell viability and apoptosis in human amniotic fluid-derived stem cells with natural cryoprotectants.

A previous study demonstrated that disaccharides, antioxidants, and caspase inhibitors can be used in freezing solutions to reduce the concentration of Me2SO from the current standard of 10% (v/v) to 5% (v/v) or 2.5% and to eliminate fetal bovine serum (FBS) for the cryopreservation of human amniotic fluid-derived stem cells (AFSCs). Hence, this study investigated whether an irreversible inhibitor of caspase enzymes, benzyloxycarbonyl-Val-Ala-dl-Asp-fluoromethylketone (zVAD-fmk), could be used in post-thaw culture media to increase the survival rate of AFSCs.

Ginkgolide C inhibits platelet aggregation in cAMP- and cGMP-dependent manner by activating MMP-9.

In this report, we investigated the effect of ginkgolide C (GC) from Ginkgo biloba leaves in collagen (10 mug/ml)-stimulated platelet aggregation. It has been known that matrix metalloproteinase-9 (MMP-9) is released from human platelets, and that it significantly inhibited platelet aggregation stimulated by collagen. Zymographic analysis confirmed that pro-MMP-9 (92-kDa) was activated by GC to form an activated MMP-9 (86-kDa) on gelatinolytic activities.

Chemopreventive and cytotoxic effect of genistein against human breast cancer cell lines was investigated. Genistein inhibited cell proliferation in estrogen receptor-positive (MCF-7) and estrogen receptor-negative (MDA-MB-231) human breast carcinoma cell lines. Cytochrome P450 (CYP) 1A1-mediated ethoxyresorufin O-deethylase (EROD)activity was inhibited by genistein in a concentration-dependent manner.

Chemopreventive effect of protein extract of Asterina pectinifera in HT-29 human colon adenocarcinoma cells.

We investigated the effect of protein extract of Asterina pectinifera on the activity of 4 enzymes that may play a role in adenocarcinoma of the colon: quinone reductase (QR), glutathione S-transferase (GST), ornithine decarboxylase (ODC), and cyclooxygenase (COX)-2. QR and GST activity increased in HT-29 human colon adenocarcinoma cells increased that had been exposed to 4 concentrations of the protein extract (80, 160, 200, and 240 microg/mL). Additionally, 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced ODC activity decreased significantly in cells exposed to the extract in concentrations of 160 microg/mL (p<0.
