Rosuvastatin promotes bone growth in mice with achondroplasia symptoms

Skeletal dysplasia is a group of rare diseases that afflict skeletal growth through abnormalities in bone and cartilage. Its onset hits at the fetal stage and is caused by genetic mutations. A mutation in the gene encoding fibroblast growth factor receptor 3 (FGFR3) has been associated with two types of skeletal dysplasia, thanatophoric dysplasia (TD), a skeletal dysplasia that cause serious respiratory problems at birth and is often lethal, and achondroplasia (ACH), which causes stunted growth and other complications throughout life. Several experimental treatments have been considered, but none are commercially available.

The need for new drug compounds that can combat skeletal dysplasia has led the Noriyuki Tsumaki group at CiRA, Kyoto University, to consider iPS cell technology. In a joint study with Associate Professor Hideaki Sawai of Hyogo College of Medicine and Team Leader Shiro Ikegawa of RIKEN, Professor Tsumaki's team screened molecules based on their ability to rescue TD-iPSCs from degraded cartilage. Molecules known to affect FGFR3 signaling and/or the metabolism of chondrocytes, the cells responsible for growing cartilage, were identified as good candidates. More importantly, so too were statins, a class of drugs renown for their action against cholesterol and investigated because they have anabolic and protective effects on chondrocytes.

The authors used iPS cells generated from the fibroblasts of both healthy individuals (WT-iPSC) and TD patients (TD-iPSC). Chondrocytes differentiated from TD-iPSC produced less cartilage than those from WT-iPSC and also had a lower proliferation rate and greater apoptosis, properties that were attributed to a gain of function by the mutated FGFR3. Adding statin recovered the cartilage formation in TD-iPSC and increased the proliferation rate. Coincidently, the group observed increased expressions of SOX9, a chondrocytic transcription factor, and of COL2A1 and ACAN, two cartilage extracellular components, all of which are down-regulated in TD patients. Moreover, statin treatment was found to accelerate the degradation of the FGFR3 protein in chondrogenically differentiated TD-iPSC, a process inhibited in TD cases.

FDA Approves Cerdelga (eliglustat) for Type 1 Gaucher Disease

The U.S. Food and Drug Administration today approved Cerdelga (eliglustat) for the long-term treatment of adult patients with the Type 1 form of Gaucher disease, a rare genetic disorder.

Gaucher disease occurs in people who do not produce enough of an enzyme called glucocerebrosidase. The enzyme deficiency causes fatty materials to collect in the spleen, liver and bone marrow. The major signs of Gaucher disease include liver and spleen enlargement, low red blood cell counts (anemia), low blood platelet counts and bone problems.

Cerdelga is a hard gelatin capsule containing eliglustat that is taken orally. In patients with Gaucher disease Type 1, the drug slows down the production of the fatty materials by inhibiting the metabolic process that forms them. Type 1 Gaucher disease is estimated to affect about 6,000 people in the United States.

New class of compounds protect brain cells from traumatic brain injury

A new class of compounds has now been shown to protect brain cells from the type of damage caused by blast-mediated traumatic brain injury (TBI). Mice that were treated with these compounds 24-36 hours after experiencing TBI from a blast injury were protected from the harmful effects of TBI, including problems with learning, memory, and movement.

Traumatic brain injury caused by blast injury has emerged as a common health problem among U.S. servicemen and women, with an estimated 10 to 20 percent of the more than 2 million U.S. soldiers deployed in Iraq or Afghanistan having experienced TBI. The condition is associated with many neurological complications, including cognitive and motor decline, as well as acquisition of psychiatric symptoms like anxiety and depression, and brain tissue abnormalities that resemble Alzheimer's disease.

"The lack of neuroprotective treatments for traumatic brain injury is a serious problem in our society," says Andrew Pieper, M.D., Ph.D., senior study author and associate professor of psychiatry, neurology, and radiation oncology at the University of Iowa Carver College of Medicine. "Everyone involved in this work is motivated to find a way to offer hope for patients, which today include both military personnel and civilians, by establishing a basis for a new treatment to combat the deleterious neuropsychiatric outcomes after blast injury."

It is known that TBI, as well as certain neurodegenerative diseases, damages axons - the tendril-like fibers that sprout from brains cells (neurons) and form the connections called synapses. In TBI, axon damage is followed by death of the neuron. The new study, published Sept. 11 in the journal Cell Reports, shows that a group of compounds, called the P7C3 series, blocks axon damage and preserves normal brain function following TBI.

Pieper led the team of scientists that discovered the P7C3 compound several years ago at UT Southwestern Medical Center. Subsequent studies showed that the root compound and its active analogs protect newborn neurons from cell death and also protect mature neurons in animal models of neurodegenerative diseases, including Parkinson's disease and amyotrophic lateral sclerosis (ALS).

The researchers have also previously shown efficacy of P7C3 molecules in brain injury due to concussion, and plan to investigate whether these compound might be applicable in stroke as well, given that there appear to be common factors mediating neuronal cell death in these conditions.

Two Vaccines Help Cut Bacteria That Cause Meningitis, Study Finds

Two new vaccines can reduce the spread of meningitis by reducing the number of meningitis-causing bacteria that people carry, according to a new study.

Researchers tested the two vaccines -- MenACWY-CRM and 4CMenB -- on volunteers aged 18 to 24. MenACWY-CRM cut meningitis-causing bacteria populations in the nose and throat by 39 percent and 4CMenB lowered those populations by 20 to 30 percent.

New Drug May Fight Serious Respiratory Virus in Infants

 An experimental drug shows promise in treating respiratory syncytial virus (RSV), a leading cause of pneumonia in infants, researchers report.

"We are finally making major progress in being able to treat human RSV infections -- the world's second leading cause of serious viral pneumonia, second only to influenza virus," said study author Dr. John DeVincenzo, a professor of pediatrics at the University of Tennessee College of Medicine in Memphis.

"There is no current treatment or vaccine for RSV pneumonia, and so patients were previously forced to get over the virus by themselves," he said. RSV is the leading cause of hospitalization among infants in the United States, the researchers noted.

In this small study of 140 adults, the drug, dubbed GS-5806, reduced the amount of the virus in the systems of those who received the medication.

"For the first time, we showed that once we reduce the amount of virus in patients, they very quickly started to feel better," DeVincenzo said.

Drug Gives 'New Hope' Against Heart Failure, Expert Says

In a head-to-head comparison, an experimental drug was more effective than standard treatment at preventing deaths and hospitalizations in heart failure patients.

According to the study authors, the trial was stopped early because of the marked benefit of the new drug, dubbed LCZ696. [LCZ696 is an investigational combination drug consisting of two antihypertensives (blood pressure lowering drugs), valsartan (left below) and AHU-377 (right below), in a 1:1 mixture. It is being developed by Novartis. The combination is often described as a dual-acting angiotensin receptor-neprilysin inhibitor (ARNi)]

In the trial, 26.5 percent of those getting the standard medication, enalapril (Vasotec), either died or were hospitalized due to heart failure, compared with 21.8 percent of those on the new drug. Enalapril belongs to a class of blood pressure-lowering medications known as ACE inhibitors.

"LCZ696 could become the new gold standard, replacing ACE inhibitors," said lead researcher Dr. John McMurray, a professor of cardiology at the British Heart Foundation Cardiovascular Research Center at the University of Glasgow, in Scotland.

LCZ696 combines two blood pressure drugs -- an angiotensin II receptor blocker (ARB) and the neprilysin inhibitor known as sacubitril.

"We found that LCZ696 was superior to the gold-standard ACE inhibitor for heart failure -- an ACE inhibitor being the absolute cornerstone of treatment for this problem," he said.

Not only did LCZ696 beat enalapril, but it did that even when added to other treatments, McMurray noted.

"The new treatment was very well tolerated, with no significant safety concerns," he added.
