New test for cancer, diabetes biomarkers 1000x more detailed

A new test for detecting biomarkers for cancer and diabetes is more than 1000x more detailed and 100% faster than existing methods, report researchers. Named 2D Mass Spectrometry (2DMS), the test provides a new tool in the rapidly expanding field research into the structure and function of proteins: Proteomics.

When cancer of unknown origin strikes, patient's family members face increased risk

Cancer usually begins in one location and then spreads, but in 3 percent to 5 percent of cancer patients, the tissue where a cancer begins is unknown. Family members of patients with cancers of unknown origin have a higher risk for getting those and other types of cancers, suggests a new study.

Pancreas cancer liquid biopsy flows from blood-borne packets of tumor genes

Pancreatic cancer tumors spill their molecular secrets into the blood stream, shedding their complete DNA and RNA wrapped inside protective lipid particles that make them ripe for analysis with a liquid biopsy, researchers at report.

Drugging the microbiome may treat heart disease | NOTICIAS CIENTIFICAS | Scoop.it

A first-of-a-kind drug that interferes with the metabolic activity of gut microbes could one day treat heart disease in humans, according to a mouse study. Dietary supplementation with a compound that is naturally abundant in red wine and olive oil prevented gut microbes from turning unhealthy foods into metabolic byproducts that clog arteries.

Many unexpected genetic variants hamper personalized medicine

In recent decades much hope has been based on the development of personalized drug treatments, in which genetic tests determine the choice and optimal dose of medication for each individual patient. However, the real breakthrough is still to be seen, and now researchers show in two separate scientific papers that many more gene variants affect how a person responds to medication than previously thought – and thus that today’s analytical tools are too coarse.

Researchers find out cause of mutations that are not in genetic material

Researchers find out cause of mutations that are not in genetic material | NOTICIAS CIENTIFICAS | Scoop.it

Proteins are like bricks that form our cells and they are built by the orders given by our genetic material, DNA. In human diseases, eventually DNA alterations modify proteins and they don't do their normal function, either by excess or defect. But recently scientists have started to find alterations of proteins without an obvious damage of the gene that produces them.

The role sphingolipids play in the death of cancer cells is now better understood, thanks to a recent study. The research traces how levels of various sphingolipids spike inside cancer cells when the cells are undergoing a highly organized form of cellular death called apoptosis.

Scientists predict activity of human genes

Genetically identical sibling cells do not always behave the same way. So far this has been attributed to random molecular reactions. Now systems biologists have discovered an overlooked consequence of the spatial separation of cells into a nucleus and a cytoplasm. Building on top of this insight they could predict with supercomputers the activity of genes in individual human cells.

Cancer: Pinpoint targeting instead of shotgun approach, say experts | NOTICIAS CIENTIFICAS | Scoop.it

Integrins help cells communicate with and adapt to their environment. Also cancer cells depend on their properties to survive and spread throughout the body. Now scientists have successfully developed a small, highly active molecule that binds to a specific integrin that operates in many types of cancer. In the future it may allow patient-specific diagnoses and subsequent targeted treatment of tumor cells.

Research reveals promising novel strategy to target cancer-causing protein

The mechanism by which tumor cells elevate levels of MDM4, a protein that is highly expressed in cancer cells but not in normal adult tissues, has been revealed by researchers. The team has also found that the mechanism can be interfered with antisense oligonucleotides to suppress cancer growth.
