La Jolla Institute's new RNAi Center to focus on genetics behind myriad diseases

A major Center that will propel scientific efforts to pinpoint the specific genes involved in causing immune diseases, cancer and other diseases will be opened today at the La Jolla Institute for Allergy & Immunology.

Researchers helps explain how the adult brain cleans out dead brain cells and produces new ones

Adult brains generate thousands of new brain cells called neurons each day; however only a small fraction of them survive. The rest die and are consumed by scavenger cells called phagocytes. Until now, scientists have not fully understood how this process works, which phagocytes are unique in the brain, and how the removal of dead neurons influences the production of new neurons.

Scientists reveal why human heart has little regenerative capacity

Stem cell researchers at UCLA have uncovered for the first time why adult human cardiac myocytes have lost their ability to proliferate, perhaps explaining why the human heart has little regenerative capacity.

Flatworms provide new insight into organ regeneration, evolution of mammalian kidneys

Our bodies are perfectly capable of renewing billions of cells every day but fail miserably when it comes to replacing damaged organs such as kidneys. Using the flatworm Schmidtea mediterranea-famous for its capacity to regrow complete animals from minuscule flecks of tissue-as an eloquent example, researchers at the Stowers Institute for Medical Research demonstrated how our distant evolutionary cousins regenerate their excretory systems from scratch.

Researchers team up to combat age-related macular degeneration

A professor at the University of California, Riverside Bourns College of Engineering has received a $100,000 grant to develop a new technique to fight a disease that gradually destroys vision.

New finding about cell metabolism may have implications for neurodegenerative disorders

Cells are the building blocks of the human body. They are a focus of scientific study, because when things go wrong at the cellular and molecular level the consequences for human health are often significant.

Stem cells could provide sperm for infertile males

Researchers have been successful in creating sperm-producing germ cells from stem cells in a lab and transferred them into infertile mice, which after the treatment were able to produce healthy offspring. This new development could help thousands of infertile men become fathers if the method proves similarly effective in humans.

Scientists convert human skin cells into forebrain neurons

Columbia University Medical Center researchers have for the first time directly converted human skin cells into functional forebrain neurons, without the need for stem cells of any kind.

Roadmap to overcome obstacles for using induced pluripotent stem cells

The possibility of developing stem cells from a patient's own skin and using them to treat conditions as diverse as Parkinson's disease, Alzheimer's disease and cancer has generated tremendous excitement in the stem cell research community in recent years. Such therapies would avoid the controversial need for using stem cells derived from human embryos, and in theory, also bypass immunological problems inherent in using cells from one person to treat another.

Conference to focus on connection between fluid balance and hypertension

Each day we consume liquids in order to keep hydrated and maintain our body's fluid balance. But just as a water balloon can get overtaxed by too much liquid, the human body is negatively affected when it retains fluids because it is unable to eliminate them properly. One of the key variables influencing how much fluid we hold in our bodies is ordinary table salt.

Cancer Research UK honors Nottingham scientist with prestigious award

A University of Nottingham scientist who uses fruit flies to study the genetics of cancer has won a prestigious award from Cancer Research UK.

Taxoxifen combined with dasatinib reverses chemo-resistance in breast cancer cells

Taking a leukemia chemotherapy drug may help breast cancer patients who don't respond to tamoxifen overcome resistance to the widely-used drug, new research from the Kimmel Cancer Center at Jefferson suggests.

Researchers reveal molecular mechanisms responsible for organizing intestinal epithelium

How do cells know where to position themselves and where to accumulate in order to carry out their functions correctly within each organ? Researchers with the Colorectal Cancer Lab at IRB Barcelona have revealed the molecular mechanisms responsible for organizing the intestinal epithelium into distinct comportments, defined by frontiers or territories.

Therapeutic hypothermia might not be effective for children after heart attack

Intravenous delivery of cold fluids to reduce body temperature quickly after a heart attack and improve neurologic outcomes may not be as effective in children as it is in adults, according to a study reported in Therapeutic Hypothermia and Temperature Management, a peer-reviewed journal published by Mary Ann Liebert, Inc.

Researchers examine drug that has potential to stop Parkinson's progression

Researchers from Michigan State University's College of Human Medicine, Van Andel Research Institute and the Translational Genomics Research Institute are investigating a drug that has the potential to not only alleviate Parkinson's symptoms but also halt the disease's progression.

Scientist discovers novel way to convert human skin cells into neurons

A scientist at the Gladstone Institutes has discovered a novel way to convert human skin cells into brain cells, advancing medicine and human health by offering new hope for regenerative medicine and personalized drug discovery and development.

Invadopodia could help survival of cancer cells

Delicate, threadlike protrusions used by cancer cells when they invade other tissues in the body could also help them escape control mechanisms supposed to eliminate them, a research group led by led by Bradley Davidson in the University of Arizona's department of molecular and cellular biology reports in Nature Cell Biology.

U.S. Judge approves federal funding for embryonic research

Federal funding of human embryonic stem cell (hESC) research is now legal in the United States. Chief judge of the US District Court for the District of Columbia Royce Lamberth has ruled on the case Sherley et al. v. Sebelius, in favor of hESC research. This overturns an existing law that prohibits the government from funding research that destroys the embryo.

Carcinogenesis is just another form of speciation, proposes new theory

Cancer patients may view their tumors as parasites taking over their bodies, but this is more than a metaphor for Peter Duesberg, a molecular and cell biology professor at the University of California, Berkeley.
