Tiny carbon nanotube pores make big impact

Tiny carbon nanotube pores make big impact

A team led by the Lawrence Livermore scientists has created a new kind of ion channel consisting of short carbon nanotubes, which can be inserted into synthetic bilayers and live cell membranes to form tiny pores that transport water, protons, small ions and DNA. These carbon nanotube “porins” have significant implications for future health care and bioengineering applications. Continue reading

First atlas of body clock gene expression informs timing of drug delivery

First atlas of body clock gene expression informs timing of drug delivery

A new effort mapping 24-hr patterns of expression for thousands of genes in 12 different mouse organs — five years in the making — provides important clues about how the role of timing may influence the way drugs work in the body. A study detailing this veritable “atlas” of gene oscillations, never before described in mammals, is published this week in the Proceedings of the National Academy of Sciences Continue reading

How lymph nodes expand during disease

How lymph nodes expand during disease

CANCER RESEARCH UK and UCL scientists have discovered that the same specialised immune cells that patrol the body and spot infections also trigger the expansion of immune organs called lymph nodes, according to a study published in Nature . Continue reading

Blood Test Helps Predict Relapse in Patients with Autoimmune Disease Affecting the Kidneys

Blood Test Helps Predict Relapse in Patients with Autoimmune Disease Affecting the Kidneys

In patients with an autoimmune disease that often involves the kidneys, monitoring the blood for autoantibodies may help doctors predict the chance of relapse. The findings are from a study appearing in an upcoming issue of the Journal of the American Society of Nephrology ( JASN ). Such measures may help protect patients’ kidney health. Continue reading

Researchers at the University of Connecticut have found a new way to identify protein mutations in cancer cells. The novel method is being used to develop personalized vaccines to treat patients with ovarian cancer. Continue reading

Diabetic men with low testosterone run higher risk of developing atherosclerosis

Diabetic men with low testosterone run higher risk of developing atherosclerosis

Men who have low testosterone and Type 2 diabetes face a greater risk of developing atherosclerosis — a condition where plaque builds up in the arteries — than men who have diabetes and normal testosterone levels, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism ( JCEM ). Atherosclerosis occurs when fats, cholesterol and other substances build up in and on the walls of the body’s arteries. This can restrict blood flow through the body’s blood vessels.

Molecular ‘breadcrumb trail’ that helps melanoma spread found

Molecular ‘breadcrumb trail’ that helps melanoma spread found

Cancer Researchers UK scientists have discovered that melanoma cells are drawn to follow the ‘trail’ of a naturally-occurring molecule in the body, which directs this serious type of skin cancer to spread, according to research published in PLOS Biology . The team at the Cancer Research UK Beatson Institute at the University of Glasgow, revealed that melanoma cells give themselves the ‘green light’ to move using the molecule — a type of fatty chemical called lysophosphatidic acid (LPA). This signal prompts them to travel and spread in the body. Continue reading
