Atherosclerotic Plaque in Mice Decreased by Genetically Engineered Tomatoes

Scientists from UCLA’s School of Medicine genetically engineered tomatoes to product 6F–a peptide that mimics the chief protein in HDL (“good cholesterol”). The tomatoes were consumed by mice that did not have the ability to purge LDL (“bad cholesterol”) from their blood. The mice that ate the genetically engineered tomatoes “had less inflammation and reduced atherosclerosis (plaque build-up in the arteries)” and had higher levels of HDL (details of effects Click here to read more…

New Chloroplast Discovery Could Allow Us to Control Ripening in Fruits and Other Crops

Biologists from the University of Leicester have found that chloroplast biogenesis is regulated by the ubiquitin proteasome system (UPS), a process that causes unwanted proteins in cells to break down. Researchers theorize that they can use specific proteins to regulate chloroplast function, including “the conversion of chloroplasts into highly-pigmented chromoplasts during the ripening of fruit.” (details of how SP1 gene may be important in controlling fruit ripening available through link Click here to read more…

A Path to Smarter Antibiotics? Mass Spectrometry Now Lets Scientists See How Antibiotics Work Inside Living Cells

Researchers from Cornell Medical College report that mass spectrometry (which is a tool commonly used to identify lipids and proteins by weighing individual molecules) can for the first time ever give scientists insight into how antibiotics work inside living cells to kill microbes. This new application of mass spectrometry can enhance our ability to develop more effective and less drug-resistant antibiotics. The need for new antibiotics is a particularly pressing Click here to read more…

SurgOptix Changes The Way We View Cancer

 “I feel more like a butcher than a surgeon,” said a doctor at the Mayo Clinic in Rochester, Minnesota to Kirk Knight of SurgOptix, Inc. The surgeon was specifically referring to oncology surgeries in which the tumor has metastasized to surrounding tissue. Resecting the tumor surgically involves having to hack away at healthy tissue neighboring the tumor region. While there is plenty of research aimed at “curing” cancer, and even Click here to read more…
