Glutathione is the most abundant natural antioxidant in cells. It protects them from damage and regulates a number of important functions, including cell proliferation and death, the synthesis of the genetic material and proteins and the activation of gene expression. These functions are regulated by changes in the concentration of glutathione, but the current methods...

What does green, yellow, or brown phlegm mean?
Phlegm is a type of mucus that is produced in the lungs and nearby lower respiratory tract airways. This kind of mucus has a crucial role in preventing germs and materials from entering the airways and lungs and potentially causing an infection. Other areas of the body, including the upper respiratory tract (nose, mouth, and...

T-cells lacking HDAC11 enzyme perform more effectively in destroying cancer cells
GW Cancer Center researchers identified the HDAC11 enzyme as an epigenetic checkpoint of T-cell function in the treatment of cancer tumors WASHINGTON (July 17, 2017) — Researchers at the George Washington University (GW) Cancer Center have discovered a new role for the enzyme, histone deacetylase 11 (HDAC11), in the regulation of T-cell function. T-cells can...

Simple bladder cancer test can accurately predict the return of the disease for 80% of patients
Researchers have developed a machine which can detect a protein called TERT People suffering with bladder cancer often have high levels of TERT in their urine Detecting presence of TERT early could lead to earlier diagnosis and treatment Bladder cancer is the seventh most common cancer in the UK, statistics show A simple bladder cancer test developed...

A new weapon for the war on cancer
Cancerous tumors are formidable enemies, recruiting blood vessels to aid their voracious growth, damaging nearby tissues, and deploying numerous strategies to evade the body’s defense systems. But even more malicious are the circulating tumor cells (CTCs) that tumors release, which travel stealthily through the bloodstream and take up residence in other parts of the body,...

Tumor Test Helps Identify Which Breast Cancers Don’t Require Extra Treatment
For years, doctors have focused on detecting breast cancer at the earliest possible moment after a tumor develops so treatment can start right away. But more and more studies are showing many small, early tumors don’t present a danger. So, when is it safe to remove a tumor but skip additional treatments like tamoxifen, chemotherapy...

This New Gene-Editing Technique Can Spot CRISPR’s Mistakes
IN BRIEF Scientists have developed a tool that can test an entire genome against a CRISPR molecule to predict potential errors and interactions. This will allow doctors to ensure treatments are safer and more effective. EDITING THE EDITOR The CRISPR gene-editing tool is already in use by scientists all over the world who are racing to cure...

Combined molecular biology test is the first to distinguish benign pancreatic lesions
When performed in tandem, two molecular biology laboratory tests distinguish, with near certainty, pancreatic lesions that mimic early signs of cancer but are completely benign. The lesions almost never progress to cancer, so patients may be spared unnecessary pancreatic cancer screenings or operations. The two-test combination is the only one to date that can accurately...

Blood cell discovery identifies patients with aggressive prostate cancer
Patients who have aggressive prostate cancer could be identified by a highly accurate and simple blood test, according to an early study by Queen Mary University of London (QMUL). The research discovered rare cells in the blood that could be used to identify patients who are 10 times more likely to die of their prostate...

Predicting autism: Study links infant brain connections to diagnoses at age 2
Researchers use MRIs to make connections between brain regions to predict which high-risk infants will develop autism. For the first time, autism researchers used MRIs of six-month olds to show how brain regions are connected and synchronized, and then predict which babies at high risk of developing autism would be diagnosed with the condition...
