Background: The putative functions of the cellular prion protein (PrPc) are believed to be associated with cell signaling, differentiation, survival, and cancer progression. With respect to cancer development and progression, elevations and mutations of PrPc expression have been shown to increase the risk for malignancy and metastasis in breast and colorectal cancer. Since both natural supplements and direct regulation of PrPc expression contribute to inhibition of cancer progression and growth, we hypothesized that knockdown of PrPc could lead to an enhanced synergic effect on the inhibition of cancer growth by fucoidan. Materials and Methods: PrPc expression was suppressed in HT29 human colon cancer cells by utilizing small-interfering RNA (si-PRNP), and cells were subsequently used to study the antiproliferative and anticancer effects of fucoidan treatment of HT29 human colon cancer cells. Results: Fucoidan treatment significantly inhibited growth and reduced cyclin and cyclin-dependent kinase (CDK) expression in HT29 colon cancer cells. Furthermore, silencing PrPc expression with si-PRNP amplified the fucoidan-induced changes in cell proliferation, apoptosis, and migration. Intraperitoneal injection of si-PRNP with fucoidan reduced proliferation and tumor volume in Balb/c nude mice. This enhanced antitumor efficacy was associated with decreased angiogenesis. Conclusion: Combination of fucoidan with silencing of PrPc has a synergic effect on the inhibition of HT29 colon cancer cell growth. Furthermore, we provide evidence for the therapeutic application of PrPc silencing with other anticancer drugs for cancer.

Chronic renal failure (CRF) is a major public health problem worldwide. In this work, we investigated the effects of a purified Laminaria japonica polysaccharide (LJP61A) on the renal function using adenine-induced CRF mice model. Results exhibited that adenine treatment caused serious renal pathological damages and elevation of serum creatinine and blood urea nitrogen of mice. However, these changes could be significantly reversed by the administration of LJP61A in a dose-dependent manner. Additionally, LJP61A could dramatically reduce the weight loss, improve the urine biochemical index, and regulate the electrolyte disturbance of CRF mice. These results suggested that the renal functions of adenine-induced CRF mice could be improved by LJP61A, which might be developed to a potential therapeutic agent for CRF patients.

Benefits of A Ketogenic Approach Keto diets have been proven to be beneficial for those with diabetes, high cholesterol, epilepsy, insulin resistance, celiac disease, and many other health problems. One of the major benefits of keto is that it is a gluten free diet. Many with celiac or gluten intolerance go keto and notice health improvements. Eating keto is also helpful for those eating a carbohydrate toxic diet. To connect with Dr. Osborne visit: On the web: https://drpeterosborne.com/ Facebook: https://www.facebook.com/DoctorPeterO...

Background/Aim: Administration of cisplatin in cancer patients is limited by the kidney-related adverse effects; however, a protective strategy is absent. We hypothesized that fucoidan protects the proximal tubule epithelial (TH-1) cells against the effects of cisplatin. Materials and Methods: To assess the effect of fucoidan, its effect on reactive oxygen species (ROS) formation, endoplasmic reticulum (ER) stress response, DNA damage response (DDR), apoptosis, and cell-cycle arrest in TH-1 cells was investigated. Results: Cisplatin increased the accumulation of ROS, leading to excessive ER stress. In presence of cisplatin, treatment of TH-1 cells with fucoidan significantly reduced the ER stress by maintaining the complex of GRP78 with PERK and IRE1α. In particular, fucoidan enhanced the antioxidative capacity through up-regulation of PrPC. Furthermore, fucoidan suppressed cisplatin-induced apoptosis and cell-cycle arrest, whereas silencing of PRNP blocked these effects of fucoidan. Conclusion: Fucoidan may be a potential adjuvant therapy for cancer patients treated with cisplatin as it preserves renal functionality.

This study investigated the protective effect of the butanol (BuOH) fraction from Laminaria japonica (BFLJ) extract on high glucose-induced oxidative stress in human umbilical vein endothelial cells (HUVECs). Freeze-dried L japonica was extracted with distilled water, and the extracted solution was mixed with ethanol then centrifuged. The supernatant was subjected to sequential fractionation with various solvents. The BuOH fraction was used in this study because it possessed the strongest antioxidant activity among the various solvent fractions. To determine the protective effect of the BFLJ, oxidative stress was induced by exposing of HUVECs to the high glucose (30 mM) or normal glucose (5.5 mM) for 48 hr. Cell viability, lipid peroxidation, glutathione (GSH) concentration, and antioxidant enzyme activities such as catalase, superoxide dismutase (SOD), glutathione peroxidase (GSH-px), and glutathion reductase (GSH-re) were measured. Exposure of HUVECs to high glucose for 48 hr resulted in a significant (p

Fucoidan is a unique bioactive and dietary polymer enriched mainly in the cell wall matrix of the brown seaweeds. This present study was intended to reveal the antigenotoxicity effect of fucoidan on 4-nitroquinolin-1-oxide (4-NQO) induced genetics damage and apoptosis in mice bone marrow cells. The 4-NQO caused genetic damages in the form of chromosome/chromatic breakage was estimated by micronuclei assay whereas apoptosis by annexin-V FITC kit and DNA damage by comet assay kit. In addition, oxidative damage in terms of plasma lipid peroxidation (LPO) and 8-OHdG was also estimated. In the experimental regime, six groups with each in five either sex of mice were used. Fucoidan constituted (50,100,200 mg/kg bwt) by orally for 5 days consequently and on 6th day, 4-NQO was administered (7.5 mg/kg bwt) by i.p. The results clearly show that negative control (H2O) and fucoidan alone constituted mice were not exhibited significant effect on LPO, genetic damages whereas positive control group (4-NQO 7.5 mg/kg bwt, i.p.) showed significant effect on genetic damage by showing increased level of LPO (6.25 vs 1.3 μM MDA), 8-OHdG (12 vs 4%), micronuclei about six-fold, 5-fold of comet, and 4-fold of apoptosis when compared with negative control, 11.6 ± 2.07, 5.00 ± 1.58, and 4.14 ± 0.65 respectively. Fucoidan pretreatment significantly protected the 4-NQO-induced genetic damage by 77% decreased level of micronuclei and 96% comet at dose of 200 mg/kg bwt over the positive control whereas LPO, 8-OHdG, and apoptosis were restored as equal to negative control. This study found as fucoidan possessing significant antigenotoxicity property by protecting 4-NQO-induced genetic damage in mice bone marrow cells as dose dependent manner suggest as valuable food supplements and medicine for mankind from environmental toxicants.

Protective effect of fucoidan from Fucus vesiculosus on liver fibrosis via the TGF-β1/Smad pathway-mediated inhibition of extracellular matrix and autophagy Jingjing Li,1 Kan Chen,1 Sainan Li,1 Jiao Feng,1 Tong Liu,1 Fan Wang,1 Rong Zhang,1,2 Shizan Xu,1,2 Yuqing Zhou,1,3 Shunfeng Zhou,1,3 Yujing Xia,1 Jie Lu,1 Yingqun Zhou,1 Chuanyong Guo1 1Department of Gastroenterology, Shanghai Tenth People’s Hospital, Tongji University School of Medicine, Shanghai, 2The First Clinical Medical College of Nanjing Medical University, Nanjing, 3Department of Gastroenterology, The First Affiliated Hospital of Soochow University, Suzhou, People’s Republic of China Abstract: Liver fibrosis is a dynamic reversible pathological process in the development of chronic liver disease to cirrhosis. However, the current treatments are not administered for a long term due to their various side effects. Autophagy is initiated to decompose damaged or excess organelles, which had been found to alter the progression of liver fibrosis. In this article, we hypothesized that fucoidan from Fucus vesiculosus may attenuate liver fibrosis in mice by inhibition of the extracellular matrix and autophagy in carbon tetrachloride- and bile duct ligation-induced animal models of liver fibrosis. The results were determined using enzyme-linked immunosorbent assay, quantitative real-time polymerase chain reaction, Western blotting, and immunohistochemical staining. Fucoidan from F. vesiculosus could inhibit the activation of hepatic stellate cells and the formation of extracellular matrix and autophagosomes, and its effect may be associated with the downregulation of transforming growth factor beta 1/Smads pathways. Fucoidan, as an autophagy and transforming growth factor beta 1 inhibitor, could be a promising potential therapeutic agent for liver fibrosis.
