Lithium chloride could offer effective treatment against osteoarthritis

Bioengineers from Queen Mary University of London (QMUL) have shown for the first time that lithium chloride, a common drug used to treat mental health disorders, could offer an effective treatment against osteoarthritis by disrupting the length of the cells' antennae called primary cilia.

Publishing in the journal FASEB, the scientists show that medical manipulation of the primary cilia, which are tiny hair-like structures protruding from the surface of most human cells, disrupts a key biological process called 'Hedgehog Signalling'.

Osteoarthritis is a painful disease affecting millions of people. It results from the cartilage breaking down at the joints and leads to difficulties in moving around and being active. Being able to control Hedgehog Signalling has previously been shown to reduce the severity of arthritis.

Praziquantel treatment safe for pregnant women after first trimester



Praziquantel.svg
A study by Rhode Island Hospital researchers confirmed that a drug used to treat a disease afflicting millions of people in developing countries is safe to give pregnant women following their first trimester. The finding could prove critical to the care of pregnant women and lactating women with schistosomiasis, a disease caused by a parasitic worm, who were denied the drug out of concern for their health and the health of their fetuses.


Authored by Jennifer F. Friedman, M.D., Ph.D., MPH, director of clinical studies for the Center for International Health Research at Rhode Island Hospital, the study found that praziquantel does not lead to adverse events for the pregnant woman or her newborn. The study was published today in The Lancet Infectious Diseases.

"Millions of women, many of whom are in a multi-year, cyclical pattern of pregnancy and breast-feeding, are denied praziquantel," said Friedman. "The accumulation of evidence shows that commencement of this treatment after the first trimester does not adversely affect the mother or fetus. We wanted to conduct this study to demonstrate that this drug is safe after the first trimester, and we remain hopeful that public health policies will change. Deferring treatment only exacerbates the morbidity of the patients."

Early trial results in lung cancer



Erlotinib Structural Formulae.png


Results from early phase trials investigating different therapeutic agents in lung cancer patients were presented during the third Presidential Session at the European Cancer Congress in Vienna, Austria. Here we summarise two studies reported at the session.

Erlotinib (structure) plus bevacizumab promising in EGFR T790M-positive advanced NSCLC patients. 

Rolf Stahel, from University Hospital Zurich in Switzerland, presented the findings of the BELIEF trial [1] on behalf of his fellow investigators from the Spanish Lung Cancer Group and the European Thoracic Oncology Platform. The phase II trial enrolled 109 patients with metastatic or locally advanced non-squamous non-small-cell lung cancer (NSCLC) harbouring activating epidermal growth factor receptor (EGFR) mutations (either the exon 19 deletion or the exon 21 L858R point mutation).

Of these, 37 (33.9%) patients also carried the EGFR T790M mutation at baseline, while the remaining 72 participants were negative for T790M.

Patients were treated with a combination of everolimus and bevacizumab on the basis of previous preclinical results suggesting that inhibiting both the EGFR and vascular EGFR pathways could be beneficial in the presence of the T790M mutation, explained Stahel.

After a median follow-up of 17.5 months, progression-free survival (PFS) was a median of 13.8 months in the overall cohort, with times of 16.0 and 10.5 months for the T790M-positive and -negative groups, respectively. The corresponding 1-year PFS rates were 56.7%, 72.4% and 49.4%.

Complete responses were achieved by 6.4% of all study participants, 8.1% of those positive for T790M and 5.6% of T790M-negative patients, while partial responses were achieved by 69.7%, 62.2% and 73.6% of patients, respectively.

New synthetic process helps study key molecule involved in diabetes, inflammation, aging



Glucosepane.svg


A synthetic process developed at Yale University will allow researchers to study a key molecule involved in diabetes, inflammation, and human aging.

The new process synthesizes glucosepane, which is considered a critical chemical link in both diabetes and aging. It is also an independent risk factor for long-term microvascular complications in diabetes.

In a study published this week in the journal Science, senior author David Spiegel and his colleagues describe the new synthesis, as well as a new synthetic methodology, which may have applications beyond the current research.

"Glucosepane forms in all human beings during the aging process, and also forms during various diseases, including diabetes," said Spiegel, a professor of chemistry and pharmacology at Yale. "It is unknown what role glucosepane might play in aging and in these diseases, but several hypotheses have been proposed. With access to synthetic glucosepane, we will now be able to generate tools to examine the role this molecule plays in human health and also, perhaps, develop molecules to inhibit or reverse its formation."
Until now, it has been difficult to study glucosepane effectively. There is a scarcity of chemically homogeneous glucosepane available for scientists to examine -- due to its unusual structure and properties -- and researchers have been forced to rely on time-consuming extraction protocols to obtain usable material.

Glucosepane contains a rare isomer of imidazole, which has never before been observed in natural molecules, other than those in the glucosepane family. Spiegel and his colleagues developed a new methodology for synthesizing this imidazole form. The process requires only eight steps.

In an accompanying article in Science, Dale L. Boger of the Scripps Research Institute wrote that the Yale study represents "an important, yet largely underexplored, frontier for chemistry with broad implications in human health." Boger said Spiegel's methodology "is important in its own right and will find applications well beyond that envisioned by the authors."

Study could lead to better understanding of metabolic processes behind type 2 diabetes

Scientists in Sweden have discovered that human intestinal flora regulates the levels of the body's main antioxidant, glutathione, which fights a host of diseases. The findings could lead to new probiotic-delivering foods, and a better understanding of the metabolic processes behind diseases such as type 2 diabetes.

Chalk up another reason why your gut bacteria is so critical to your health — and why it could be the key to preventing a host of diseases. Scientists in Sweden have discovered that human intestinal flora regulates the levels of the body's main antioxidant, glutathione, which fights a host of diseases.

The study could lead to new probiotic-delivering foods, and a better understanding of the metabolic processes behind diseases such as type 2 diabetes, says co-author Adil Mardinoglu, a systems biology researcher at Stockholm's KTH Royal Institute of Technology.

Published in the scientific journal, Molecular Systems Biology, the findings help complete our understanding of how nonessential amino acids are synthesized to equip the body's cells with detoxifying agents and antioxidants, Mardinoglu says.

Cranberry juice consumption may protect against cardiovascular disease

In continuation of my updates on Cranberries

Results from a new study presented at the Cranberry Health Research Conference preceding the annual Berry Health Benefits Symposium 2015 in Madison, WI, revealed that cranberry juice consumption may play a role in protecting against cardiovascular disease. Presented by principal investigator, Ana Rodriguez-Mateos, PhD, from the Division of Cardiology, Pulmonology and Vascular Medicine at the University Duesseldorf, Germany, the research uncovered a potent, dose-dependent relationship between cranberry juice and improved vascular function. Because vascular dysfunction, including limitations in blood flow, is a central feature in the development of atherosclerosis - improving vascular function can have a powerful, beneficial effect on a person's cardiovascular health.

"Cranberry juice is a rich source of phytonutrients, including proanthocyanidins, anthocyanins and phenolic acids," explains Dr. Rodriguez-Mateos. "Due to this robust profile of polyphenols, our team sought to evaluate the immediate vascular impact of drinking one, 450 ml (or 16 ounces) glass of cranberry juice with a different range of concentrations of cranberry-polyphenols."

Veltassa (patiromer for oral suspension) gets FDA approval for treatment of hyperkalemia



2D chemical structure of 1260643-52-4



The U.S. Food and Drug Administration today approved Veltassa (patiromer for oral suspension) to treat hyperkalemia, a serious condition in which the amount of potassium in the blood is too high.

"Too much potassium in the blood can lead to dangerous, even fatal, changes in heart rhythm," said Norman Stockbridge, M.D., Ph.D., director of the Division of Cardiovascular and Renal Products in the FDA's Center for Drug Evaluation and Research. "It is important to have treatment options for hyperkalemia available to patients."

Potassium, a mineral that is delivered to the body by food, is needed for cells to function properly. The kidneys remove potassium from the blood to maintain a proper balance of potassium in the body. But when the kidneys are not able to remove enough potassium from the blood, the level of potassium can get too high. Hyperkalemia typically occurs in patients with acute or chronic kidney disease or heart failure, particularly in those who are taking drugs that inhibit the renin-angiotensin-aldosterone system, which regulates blood pressure and fluid balance in the body.

Orange pigment may have potential as anti-cancer drug



Caloplaca_Fenwick
An orange pigment found in lichens and rhubarb called parietin may have potential as an anti-cancer drug, scientists at Winship Cancer Institute of Emory University have discovered.

The results are scheduled for publication on October 19 in Nature Cell Biology.

Parietin, also known as physcion, could slow the growth of and kill human leukemia cells obtained directly from patients, without obvious toxicity to human blood cells, the authors report. The pigment could also inhibit the growth of human cancer cell lines derived from lung and head and neck tumors when grafted into mice.
A team of researchers led by Jing Chen, PhD, discovered the properties of parietin because they were looking for inhibitors for the metabolic enzyme 6PGD (6-phosphogluconate dehydrogenase). 6PGD is part of the pentose phosphate pathway, which supplies cellular building blocks for rapid growth. Researchers have already found 6PGD enzyme activity increased in several types of cancer cells.

"This is part of the Warburg effect, the distortion of cancer cells' metabolism," says Chen, professor of hematology and medical oncology at Emory University School of Medicine and Winship Cancer Institute. "We found that 6PGD is an important metabolic branch point in several types of cancer cells."

This work represents a collaboration among three laboratories at Winship led by Chen, Sumin Kang, PhD, assistant professor of hematology and medical oncology, and Jun Fan, PhD, assistant professor of radiation oncology. Co-first authors are postdoctoral fellows Ruiting Lin, PhD, and Changliang Shan, PhD, and former graduate student Shannon Elf, PhD, now at Harvard.

The Winship team obtained cancer cells from a patient with acute lymphoblastic leukemia, and found doses of physcion/parietin that could kill half the leukemia cells in culture within 48 hours, while the same doses left healthy blood cells unscathed. A more potent derivative of the pigment called S3 could cut the growth of a lung cancer cell line by a factor of three over 11 days, when the cells were implanted into mice.
