    Targeting metastasis-initiating cells through the fatty acid receptor CD36

    Targeting metastasis-initiating cells through the fatty acid receptor CD36

    A specific protein, CD36 found in the cell membranes of tumour cells, is responsible for taking up fatty acids. This unique CD36 activity and dependence on fatty acids distinguishes metastasis-initiating cells from other tumour cells. The work was published today in the journal Nature. Professor Benitah’s team found CD36 was present on metastatic cancer cells from patients with a range of different tumours including oral tumours, melanoma skin cancer, ovarian, bladder, lung and breast cancer. To confirm its essential role in cancer spread, they added CD36 to non-metastatic cancer cells which then caused the cells to become metastatic.

    “Although we have not yet tested this in all tumour types, we can state that CD36 ...

    High-Fat Diet Starves the Brain

    A high-fat diet of 3 days in mice leads to a reduction in the amount of glucose that reaches the brain. The mouse brain restored its sugar uptake after 4 weeks, albeit at the cost of the rest of the body. High-fat-content foods throw our bodies out of kilter. Obesity and diseases such as type 2 diabetes can be the result. But what does a high-fat diet actually do to our brain? Scientists from the Max Planck Institute for Metabolism Research in Cologne have looked into the brains of mice to understand how obesity and diabetes develop.

    “A high-fat diet reduces the uptake of blood glucose into the ...

    Impact of High-Fat Diet on Red Blood Cells may cause Cardiovascular Disease

    November 17, 2015, Categories  Biology/Biotechnology, Health/Medical

    MCP-1 released by smooth muscle and endothelial cells promotes the recruitment of monocytes and macrophages to the subendothelial cell layer. Deposition of lipids within these monocytes and macrophages then leads to development of atherosclerotic lesions.

    MCP-1 released by smooth muscle and endothelial cells promotes the recruitment of monocytes and macrophages to the subendothelial cell layer. Deposition of lipids within these monocytes and macrophages then leads to development of atherosclerotic lesions.

    This is one of the 1st studies to demonstrate the effect of red blood cells on the disease and could also affect the way patients with other health conditions, like cancer, who are prone to developing cardiovascular issues, are diagnosed and treated. “White blood cells play a key role in fueling adipose tissue (fat) inflammation and insulin resistance in obesity and also promote the clogging of arteries, or atherosclerosis, setting the stage for heart attack and stroke...

    Insulin Sensitivity: One night of Poor Sleep could equal 6 months on a High-Fat Diet, study in dogs suggests

    New research finds that one night of sleep deprivation and six months on a high-fat diet could both impair insulin sensitivity to a similar degree, demonstrating the importance of a good night's sleep on health. (stock image) Credit: © tab62 / Fotolia

    New research finds 1 night of sleep deprivation and six months on a high-fat diet could both impair insulin sensitivity to a similar degree, demonstrating the importance of a good night’s sleep on health. This study used a canine model to examine whether sleep deprivation and a high-fat diet affect insulin sensitivity in similar ways.

    When the body becomes insulin resistant, it needs to produce more insulin to keep blood sugar stable. This may eventually lead to Type 2 diabetes which is a/w heart disease...
