Novel modification of structural protein implicated

Studying a protein that gives structure to the nucleus of cells, Johns Hopkins researchers stumbled upon mutations associated with familial partial lipodystrophy, a rare disease that disrupts normal patterns of fat distribution throughout the body.

Rensselaer professor awarded NIH grant to explore cellular function with links to diverse diseases

The interior of every cell within our bodies is crisscrossed with a network of molecular highways upon which nutrients, replacement parts, and other vital materials travel to their appropriate location.

Novel therapeutic strategy for post-prostatectomy erectile dysfunction

Transplantation of mesenchymal stem cells cultivated on the surface of nanofibrous meshes could be a novel therapeutic strategy against post-prostatectomy erectile dysfunction, conclude the authors of a study which is to be presented at the 28th Annual EAU Congress later this week.

Cell fusion studies at Johns Hopkins could lead to improved treatments for muscular dystrophy

Researchers at Johns Hopkins have established a high-efficiency cell-cell fusion system, providing a new model to study how fusion works. The scientists showed that fusion between two cells is not equal and mutual as some assumed, but, rather, is initiated and driven by one of the fusion partners. The discovery, they say, could lead to improved treatments for muscular dystrophy, since muscle regeneration relies on cell fusion to make muscle fibers that contain hundreds or even thousands of nuclei.

mTORC2 plays key role in regulating memory formation

Introductions at a party seemingly go in one ear and out the other. However, if you meet someone two or three times during the party, you are more likely to remember his or her name. Your brain has taken a short-term memory - the introduction - and converted it into a long-term one.

Ampio Pharmaceuticals starts Optina clinical trial

Ampio Pharmaceuticals, Inc. announced oral dosing of the first patient in a 505(b)(2) clinical trial of the investigational drug Optina in diabetic macular edema.

MiR-182 deeply involved in memory formation within the amygdala brain structure

It takes a lot to make a memory. New proteins have to be synthesized, neuron structures altered. While some of these memory-building mechanisms are known, many are not. Some recent studies have indicated that a unique group of molecules called microRNAs, known to control production of proteins in cells, may play a far more important role in memory formation than previously thought.

FDA approves Ampio’s IND for Optina for treatment of diabetic macular edema

Ampio Pharmaceuticals, Inc. announced today that the FDA has accepted the Company's IND for Optina™ for the treatment of diabetic macular edema (DME). Ampio plans to commence enrollment in a clinical trial in the first quarter of 2013. The FDA granted Optina™ 505(b)(2) status in July, 2012. Drugs designated under this pathway can be approved on a single trial.

Biophysical Society Annual Meeting to highlight innovations in medicine, physics, and more

Honeybee silk-inspired materials; a deconstruction of the Ebola virus; how microbes evolve resistance to antibiotics; and a possible connection between Alzheimer's disease and type II diabetes are just some of the intriguing topics that will be presented at the 57th Annual Meeting of the Biophysical Society (BPS).

Scientists define structure of α-catenin protein

Scientists know that cells in all higher organisms cells need to bind to each other for the development, architecture, maintenance and function of tissues. Mysteries have remained, however, about exactly how cells manage this feat.

Researchers demonstrate significance of two proteins in nerve cell development

The study conducted by Prof. Frank Bradke's team provides indications on brain development and about the causes of diseases of the nervous system. The results have now been published in "Neuron".

Targeting km23-1 protein may slow the spread of cancer cells

The spread of cancer cells may be slowed by targeting the protein km23-1, according to researchers at Penn State College of Medicine.

Wichita State professor hopes to understand how cancer cells spread and become fatal

Through her research at Wichita State University, assistant chemistry professor Moriah Beck hopes to understand how cancer cells spread and become fatal.

Researchers solve mystery of radial glial cells

Researchers at Cold Spring Harbor Laboratory (CSHL) have solved an important piece of one of neuroscience's outstanding puzzles: how progenitor cells in the developing mammalian brain reproduce themselves while also giving birth to neurons that will populate the emerging cerebral cortex, the seat of cognition and executive function in the mature brain.

Stanford and MBL scientists win prestigious Lasker Awards

Scientists who invented new ways to study how "cargo" is moved within cells and, as a result, discovered a new biological motor protein, kinesin, at the Marine Biological Laboratory (MBL) in Woods Hole, Mass., have received the prestigious 2012 Lasker Award for Basic Medical Research, the Albert and Mary Lasker Foundation announced today.

Scientists discover new anti-cancer and anti-metastatic molecule

A new molecule with anti-cancer and anti-metastatic properties has been discovered by teams from CNRS, CEA, the Institut Curie and Inserm, in collaboration with Australian and British researchers.

FSU researchers achieve significant benchmarks in alpha-tropomyosin study

Florida State University researchers led by physics doctoral student Campion Loong have achieved significant benchmarks in a study of the human cardiac protein alpha-tropomyosin, which is an essential, molecular-level component that controls the heart's contraction on every beat.

Potential new COPD drug

A study led by researchers at Boston University School of Medicine (BUSM) has shown that a compound used in some skin creams may halt the progression of emphysema and reverse some of the damage caused by the disease. When the compound Gly-His-Lys (GHK) was applied to lung cells from patients with emphysema, normal gene activity in altered cells was restored and damaged aspects of cellular function were repaired.

Abnormalities in mitochondrial length promote development of neurodegenerative diseases

Goldilocks was on to something when she preferred everything "just right." Harvard Medical School researchers have found that when it comes to the length of mitochondria, the power-producing organelles, applying the fairy tale's mantra is crucial to the health of a cell. More specifically, abnormalities in mitochondrial length promote the development of neurodegenerative diseases such as Alzheimer's.

Implanted cells' therapeutic properties depend on their shape

Tissue implants made of cells grown on a sponge-like scaffold have been shown in clinical trials to help heal arteries scarred by atherosclerosis and other vascular diseases. However, it has been unclear why some implants work better than others.
