UCSD researchers describe surprising role of protein in embryonic development

Hematopoietic stem cells (HSCs) give rise to all blood and immune cells throughout the life of vertebrate organisms, from zebrafish to humans. But details of their genesis remain elusive, hindering efforts to develop induced pluripotent stem cell (iPSC) replacements that might address a host of blood disorders.

Induced neural stem cells hold promise for therapeutic transplantation

Induced neural stem cells (iNSCs) created from adult cells hold promise for therapeutic transplantation, but their potential in this capacity has been limited by failed efforts to maintain such cells in the desirable multi-potent NSC state without continuous expression of the transcription factors used initially to reprogram them.

Findings pave way for personalized probiotic therapies for obesity-related diseases

Our genetic makeup influences whether we are fat or thin by shaping which types of microbes thrive in our body, according to a Cornell-led study published today in the journal Cell.

Researchers discover new genetic cause of rare, complex form of epilepsy

A research team led by scientists at the Scripps Translational Science Institute has used whole genome sequencing to identify a new genetic cause of a severe, rare and complex form of epilepsy that becomes evident in early childhood and can lead to early death.

Liposomes can help prevent bacterial toxins from killing human cells

Published in Nature Biotechnology, the study at the University of Liverpool showed that specially engineered lipid (fat) bodies, called liposomes, can be used to prevent bacterial toxins from killing human cells.

Regenerative medicine may offer new standard of advanced treatment for foot and leg ulcers

These are exciting times for regenerative medicine. Unlike conventional medicines, the regenerative approach can potentially work to restore the lost functionality of tissues or organs—the major reason for intensive focus on research and development in the field.

Researchers obtain detailed picture of how Gas5 RNA interacts with steroid hormone receptors

It arises from what scientists previously described as "junk DNA" or "the dark matter of the genome," but this gene is definitely not junk.

Single mutation in beta-catenin gene can lead to infertility

Scientists from the RIKEN BioResource Center in Tsukuba, Japan, have discovered that a single mutation in the beta-catenin gene, which codes a protein known to be deeply involved in a number of developmental and homeostatic processes, can lead to infertility not through a disruption of the production of egg or sperm cells, but rather by leading to abnormalities in the morphology of the sexual organs, making natural reproduction impossible.

Researchers synthetize molecules to block virus that causes influenza A

The influenza A virus is a contagious and severe respiratory infection that affects animals but also humans. Researchers from the University of Barcelona have synthetized some molecules which are able to block the virus that causes influenza A and some of the mutations that make it resistant to common drugs.

Zinc supplements more beneficial for some people with diabetes

Researchers at the Johns Hopkins University School of Medicine and elsewhere have found that genetic differences may account for why zinc supplements are more beneficial to some people than to others for the prevention and control of diabetes. The results of their pilot study of a population of Old Order Amish is believed to be the first to point out the relevance of small genetic differences in response to zinc supplementation at play in diabetes management.

McLean Hospital lab explores use of stem cell therapy to treat epilepsy

McLean Hospital and Harvard Stem Cell Institute scientists have new evidence that stem cell transplantation could be a worthwhile strategy to help epileptics who do not respond to anti-seizure drugs.

Genetically diverse mouse model can predict human response to chemical exposures

A genetically diverse mouse model is able to predict the range of response to chemical exposures that might be observed in human populations, researchers from the National Institutes of Health have found. Like humans, each Diversity Outbred mouse is genetically unique, and the extent of genetic variability among these mice is similar to the genetic variation seen among humans.

Researchers edging closer to first ever stem cell transplants for people with Parkinson's disease

A major breakthrough in the development of stem cell-derived brain cells has put researchers on a firm path towards the first ever stem cell transplantations in people with Parkinson's disease. A new study presents the next generation of transplantable dopamine neurons produced from stem cells. These cells carry the same properties as the dopamine neurons found in the human brain.

Salk Institute researchers heal injured hearts of living mice

Researchers at the Salk Institute have healed injured hearts of living mice by reactivating long dormant molecular machinery found in the animals' cells, a finding that could help pave the way to new therapies for heart disorders in humans.

New study explains role of cilia in type 2 diabetes

Tiny extensions on cells, cilia, play an important role in insulin release, according to a new study, which is published in Nature Communications. The researchers report that the cilia of beta cells in the pancreas are covered with insulin receptors and that changed ciliary function can be associated with the development of type 2 diabetes.

U-M researchers show how neurons perform multiple functions

Researchers at the University of Michigan have shown how a single neuron can perform multiple functions in a model organism, illuminating for the first time this fundamental biological mechanism and shedding light on the human brain.

Scientists develop human stem cell disease model of Parkinson's disease in a dish

A team of scientists led by The New York Stem Cell Foundation Research Institute successfully created a human stem cell disease model of Parkinson's disease in a dish. Studying a pair of identical (monozygotic) twins, one affected and one unaffected with Parkinson's disease, another unrelated Parkinson's patient, and four healthy control subjects, the scientists were able to observe key features of the disease in the laboratory, specifically differences in the patients' neurons' ability to produce dopamine, the molecule that is deficient in Parkinson's disease.

Scientists awarded grant to investigate new drug-based treatment for NF2

Scientists from Plymouth University Peninsula Schools of Medicine and Dentistry have been awarded a grant from young person's cancer charity The Laura Crane Youth Cancer Trust to investigate a new drug-based treatment for a multi-tumour brain and nervous system cancer which affects teenagers and young adults.

Researchers develop 'smart bomb' to attack B-lineage ALL

Fatih Uckun, Jianjun Cheng and their colleagues have taken the first steps towards developing a so-called "smart bomb" to attack the most common and deadly form of childhood cancer — called B-lineage acute lymphoblastic leukemia (ALL).

Johns Hopkins researchers capture images of protein complex that keeps hearts beating

For years, a multidisciplinary team of Johns Hopkins researchers has tracked an elusive creature, a complex of proteins thought to be at fault in some cases of sudden cardiac death. As they report Nov. 5 in the online edition of Nature Communications, they have finally captured images of the complex.
