Genetic mutation that alters PIEZO1 ion channel in RBCs contributes to familial xerocytosis

A genetic mutation that alters the kinetics of an ion channel in red blood cells has been identified as the cause behind a hereditary anemia, according to a paper published this month in the Proceedings of the National Academy of Sciences by University at Buffalo scientists and colleagues.

CALHM1 channel protein releases ATP to make neural taste connections

Saying that the sense of taste is complicated is an understatement, that it is little understood, even more so. Exactly how cells transmit taste information to the brain for three out of the five primary taste types was pretty much a mystery, until now.

CALHM1 protein plays critical role in sweet, bitter and umami taste perception

Working with a multidisciplinary consortium of 19 researchers from nine institutions, Monell scientists have provided critical information to identify CALHM1, a channel in the walls of taste receptor cells, as a necessary component in the process of sweet, bitter, and umami (savory) taste perception.

Scientists discover key biochemical step underlying heart failure

Some 5.8 million Americans suffer from heart failure, a currently incurable disease. But scientists at Temple University School of Medicine's (TUSM) Center for Translational Medicine have discovered a key biochemical step underlying the condition that could aid the development of new drugs to treat and possibly prevent it.

Blocking aPKC activity can stop growth of transplanted skin tumors resistant to vismodegib

Hailed as a major step forward in the effort to develop targeted cancer therapies, a recently approved drug for the most common type of skin cancer has been a mixed blessing for patients. Although the initial response is usually dramatic, the tumors often recur as the cancer becomes resistant to treatment.

Engineering chemotherapy drugs' shape increases their ability to target and inhibit cancer cells

Bioengineering researchers at University of California, Santa Barbara have found that changing the shape of chemotherapy drug nanoparticles from spherical to rod-shaped made them up to 10,000 times more effective at specifically targeting and delivering anti-cancer drugs to breast cancer cells.

Elevated cell sugar concentrations increase hyaluronan production and promote cancer growth

According to a recent University of Eastern Finland (UEF) study, elevated cell sugar concentrations increase the production of hyaluronan which, in turn, promotes cancer growth. Regulating the production of hyaluronan may be a way to prevent the spreading of cancer.

Recombinant Newcastle disease virus kills all kinds of prostate cancer cells

A recombinant Newcastle disease virus kills all kinds of prostate cancer cells, including hormone resistant cells, but leaves normal cells unscathed, according to a paper published online ahead of print in the Journal of Virology.

Scientists uncover atomic structure of dermcidin

An international team of scientists has discovered how an important natural antibiotic called dermcidin, produced by our skin when we sweat, is a highly efficient tool to fight tuberculosis germs and other dangerous bugs.

Researchers identify second B-cell attachment receptor for Epstein-Barr virus

Epstein-Barr virus (EBV) affects more than 90 percent of the population worldwide and was the first human virus found to be associated with cancer. Now, researchers from Beth Israel Deaconess Medical Center (BIDMC) have broadened the understanding of this widespread infection with their discovery of a second B-cell attachment receptor for EBV.

FSH, LH two important hormones that regulate puberty and maturation processes

FSH and LH are two important hormones which regulate the processes of puberty and maturation. These hormones are secreted by the pituitary gland and are transported in the blood to the genitalia, where they regulate maturation.

New insights into how cells stick to each other and to other bodily structures

Research carried out by scientists at the Georgia Institute of Technology and The University of Manchester has revealed new insights into how cells stick to each other and to other bodily structures, an essential function in the formation of tissue structures and organs. It's thought that abnormalities in their ability to do so play an important role in a broad range of disorders, including cardiovascular disease and cancer.

Researchers identify new way to influence the vital serotonin signaling system

An interdisciplinary team of researchers from the University of Texas Medical Branch at Galveston and the University of Houston has found a new way to influence the vital serotonin signaling system - possibly leading to more effective medications with fewer side effects.

Berkeley Lab researchers resolve EGFR activation mystery

Researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have provided important new details into the activation of the epidermal growth factor receptor (EGFR), a cell surface protein that has been strongly linked to a large number of cancers and is a major target of cancer therapies.

Previously poorly investigated signalling pathway crucial for proliferation of prostate cancer cells

A previously poorly investigated signalling pathway is crucial for the growth and proliferation of prostate cancer cells. An international research team discovered this when studying the enzyme "soluble adenylyl cyclase" that produces the second messenger molecule cAMP.

Nitric oxide shuts down brain's repair mechanisms

Nitric oxide, a gaseous molecule produced in the brain, can damage neurons. When the brain produces too much nitric oxide, it contributes to the severity and progression of stroke and neurodegenerative diseases such as Alzheimer's. Researchers at Sanford-Burnham Medical Research Institute recently discovered that nitric oxide not only damages neurons, it also shuts down the brain's repair mechanisms.

Cloaked nanoparticles escape immune system surveillance to reach desired target

By cloaking nanoparticles in the membranes of white blood cells, scientists at The Methodist Hospital Research Institute may have found a way to prevent the body from recognizing and destroying them before they deliver their drug payloads. The group describes its "LeukoLike Vectors", or LLVs, in the January issue of Nature Nanotechnology.

Researchers discover safe and efficient way to get large molecules through the cell membrane

Living cells are surrounded by a membrane that tightly regulates what gets in and out of the cell. This barrier is necessary for cells to control their internal environment, but it makes it more difficult for scientists to deliver large molecules such as nanoparticles for imaging, or proteins that can reprogram them into pluripotent stem cells.

Research on dystrophin gene sequence could lead to treatments for Duchenne muscular dystrophy

Muscular dystrophy is caused by the largest human gene, a complex chemical leviathan that has confounded scientists for decades. Research conducted at the University of Missouri and described this month in the Proceedings of the National Academy of Sciences has identified significant sections of the gene that could provide hope to young patients and families.

Researchers report novel charge zipper principle used by proteins to form functional units

Membrane proteins are the "molecular machines" in biological cell envelopes. They control diverse processes, such as the transport of molecules across the lipid membrane, signal transduction, and photosynthesis. Their shape, i.e. folding of the molecules, plays a decisive role in the formation of, e.g., pores in the cell membrane.
