Cell signaling is vital for cells to communicate and coordinate their activities, not just in the human body, but in all organisms. There are thousands of signaling pathways, ranging from protein homeostasis to carcinogenesis and biofilm formation.

Study finds genetic vulnerability to use of menthol cigarettes

A genetic variant found only in people of African descent significantly increases a smoker's preference for cigarettes containing menthol, a flavor additive.

Study shows how neuroactive steroids inhibit activity of pro-inflammatory proteins

For the first time, scientists discovered how neuroactive steroids naturally found in the brain and bloodstream inhibit the activity of a specific kind of protein called Toll-like receptors, which have been known to play a role in inflammation in many organs, including the brain.

New model sheds light on how small cell lung cancer is initiated

Scientists from Weill Cornell Medicine have developed a stem-cell-based model of small cell lung cancer that will help them understand how the disease is initiated and how it progresses.

Scientists uncover new information about development of gastric cancer

Cardiff University researchers have uncovered new information about the underlying mechanisms for gastric cancer, providing hope of potential new therapies in the future.

Preparation, characterization of Soyasapogenol B loaded onto functionalized MWCNTs

Multi-Walled Carbon Nanotubes is the name that is derived from their structure and walls are formed by one atom thick sheet of carbon.

Identifying genetic factors that lead to squamous cell carcinoma

Skin cancer is on the rise in the United States. Squamous cell carcinoma, the second most common form of cancer in the U.S., has the highest mortality rate of all non-melanoma skin cancers. In roughly two to five percent of patients, the disease will metastasize and spread throughout the body, making it difficult to treat.

New discovery casts doubt on plasma membrane models

Like planets, the body's cell surfaces look smooth from a distance but hilly closer up. An article published in Communications Biology describes implications, unknown to date, of the way data from cell surfaces are normally interpreted; i.e. as if they lacked topographic features.

Mechanism underlying impaired allergic inflammation in children may explain hygiene hypothesis

The hygiene hypothesis may explain why asthma and other allergic airway diseases have dramatically increased over the past decades in industrialized countries.

New technique using microneedles may mean rapid diagnoses of major illnesses

When people are in the early stages of an undiagnosed disease, immediate tests that lead to treatment are the best first steps. But a blood draw -- usually performed by a medical professional armed with an uncomfortably large needle -- might not be quickest, least painful or most effective method, according to new research.

Research reviews role of protein tyrosine phosphatase in molecular biology

As the proteomics technology develops and human genomic analysis becomes easier to execute, molecules involved in the regulation of biochemical signaling pathways have become interesting subjects for researchers.

MUSC researchers link higher levels of AGEs to ER-positive breast cancer risk

Poor diet and lack of exercise are associated with cancer development, but the underlying biology is not well understood. Advanced glycation end products could offer a biological link to help us understand how certain lifestyle behaviors increase cancer risk or lessen the likelihood that an anti-cancer therapy will be effective.

Soyasapogenol B: A new drug delivery technology for therapeutics

Multi-Walled Carbon Nanotubes (MWCNTs) are characterized by walls formed by a one atom thick sheet of carbon.

Study: Cholesterol uptake is decreased in GM3S-deficient cells

Approximately 1 in every 4 deaths in the United States is caused by heart disease, according to the Centers for Disease Control and Prevention.

Breast tumors recruit bone marrow cells to boost their growth, study reveals

Tel Aviv University researchers have discovered that breast cancer tumors boost their growth by recruiting stromal cells that originate in bone marrow.

Insights into protein-protein interactions and methods for designing small molecule inhibitors

Proteins are polymers of amino acids that are linked by peptide bonds and they are one of the major classes of bio-molecules existing in a living organism. Proteins are involved in various cellular functions and events like cell signaling, cell adhesion, metabolic reactions, in the generation of immune response and many more.

Newly developed molecules may provide more reliable relief for people with autoimmune diseases

Living with an autoimmune disease can feel like an insider is attacking your body. An estimated 24 million people in the United States are affected by autoimmune diseases, a group of diseases in which a person's immune system attacks part of the person's own body.

New drug combination could kill melanoma cells more effectively, study shows

A class of cancer drugs called protein kinase inhibitors is one of the most effective treatments for melanoma. However, in many cases, tumors eventually become resistant to the drugs and cause a relapse in the patient.

Scientists alleviate schizophrenic symptoms in mice

Despite extensive research efforts, schizophrenia remains one of the least understood brain disorders. One promising area of research is in receptors on the surfaces of brain cells that help sense growth factors.

New ointment for treating brown recluse spider bites is tested on humans

The bite from a brown recluse spider (Loxosceles) can cause skin necrosis, renal failure, and even death. A new ointment is being tested in Brazil, however. Its effects have already been proven in tests conducted in cell cultures and animal models.

Rainforest vine compound makes pancreatic cancer cells susceptible to nutrient starvation

Pancreatic cancer cells are known for their ability to thrive under extreme conditions of low nutrients and oxygen, a trait known in the cancer field as "austerity." The cells' remarkable resistance to starvation is one reason why pancreatic cancer is so deadly.
