Tue, 21 Mar 2017 07:00:00 PDT

Study suggests that a mechanism of drug resistance in ER+ breast cancers could be changes to the estrogen receptor caused by two immune system molecules.

Immune cell drives heart failure in mice

Mon, 20 Mar 2017 00:00:00 PDT

A new study in mice reveals that eosinophils, a type of disease-fighting white blood cell, appear to be at least partly responsible for the progression of heart muscle inflammation to heart failure...

Fat cells step in to help liver during fasting

Mon, 20 Mar 2017 00:00:00 PDT

How do mammals keep two biologically crucial metabolites in balance during times when they are feeding, sleeping, and fasting? The answer may require rewriting some textbooks.

Lactate may be key for cancer development

Sun, 19 Mar 2017 00:00:00 PDT

New research examines the role of lactate - a molecule that is produced and accumulates during intense workout - in the formation of cancer cells.

Triple-negative breast cancer: Nanodelivery of new drug shows promise

Fri, 17 Mar 2017 07:00:00 PDT

Delivering a new drug directly into triple-negative breast cancer cells via nanoparticles stops the drug degrading before reaching target, study shows.

Researchers mapped interactions of key group of human proteins, the protein phosphatases

Fri, 17 Mar 2017 00:00:00 PDT

Coordinated activities of protein kinases and protein phosphatases ensure phosphorylation homeostasis and amplitude of signaling response, and understandably its imbalance is linked to diseases...

MS: Treatments to reverse myelin damage step closer with brain repair study

Wed, 15 Mar 2017 07:00:00 PDT

Mouse study reveals that regulatory T cells not only help to control immune system but can also stimulate regrowth of myelin, which is destroyed in MS.

Study highlights possible Achilles' heel in key immune memory cells

Tue, 14 Mar 2017 00:00:00 PDT

The capacity for memory isn't exclusive to the brain. The immune system, with its sprawling network of diverse cell types, can recall the pathogens it meets, helping it to swiftly neutralize those...

Researchers identify a new way to promote tissue regeneration

Mon, 13 Mar 2017 00:00:00 PDT

Houston Methodist researchers have identified an immune pathway that promotes the formation of a cell that can develop into new tissues and organs.

Vitamin C can target and kill cancer stem cells, study shows

Mon, 13 Mar 2017 00:00:00 PDT

A new study investigates the effectiveness of experimental drugs, a clinical drug, and natural compounds in stopping the growth of cancer stem-like cells.

How rare sugars might help control blood glucose

Fri, 10 Mar 2017 06:00:00 PDT

In an era when the label "natural" hits a sweet spot with consumers, some uncommon sugars emerging on the market could live up to the connotation.

Dental plaque DNA shows Neandertals used 'aspirin'

Fri, 10 Mar 2017 00:00:00 PDT

Ancient DNA found in the dental plaque of Neandertals - our nearest extinct relative - has provided remarkable new insights into their behaviour, diet and evolutionary history, including their use...

Molecule discovery may lead to new drugs for brain and spinal cord injury

Thu, 09 Mar 2017 07:00:00 PDT

The discovery that a small molecule from fungi stimulates axon regeneration could lead to much needed new drugs to repair central nervous system damage.
