Researchers identify biological pathway that explains why current asthma therapies fail in many cases

Asthma is an enormous public health problem that continues to grow larger, in part because scientists don't fully understand how it is caused. Existing therapies don't cure the disease and often don't even significantly alleviate the symptoms. Now, scientists from the Perelman School of Medicine at the University of Pennsylvania and Rutgers University have identified a biological pathway that potentially explains why current asthma therapies don't work well in many cases—and might be targeted to help those patients.

High dosages of antihistamines have dulling effect on genes associated with post-exercise recovery

After vigorous exercise, some 3,000 genes go to work to aid recovery by boosting muscles and blood vessels, but in the presence of high doses of antihistamines almost 27 percent of the gene response is blunted, according to University of Oregon researchers.

Distribution of c-Myc protein during asymmetric cell division influences fate, roles of activated T cells

The fates of immune cells can be decided at the initial division of a cell. Researchers at St. Jude Children's Research Hospital have discovered that the production of daughter cells with different roles in the immune system is driven by the lopsided distribution of the signaling protein c-Myc. Nudging c-Myc in one direction or the other could make vaccines more effective or advance immunotherapies for cancer treatment. The research appears online today in the scientific journal Nature.

New GHz-class NMR magnet and probe technologies introduced by Bruker at ENC 2016

At the 57th Experimental Nuclear Magnetic Resonance Conference (www.enc-conference.org), Bruker announced new GHz-class NMR magnet and probe technologies to enable expanding frontiers in structural biology, membrane protein and intrinsically disordered protein (IDP) research.

MicroRNA controls tumor cell proliferation in most aggressive large B-cell lymphoma

A recent study by researchers at Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine showed that a microRNA called miR-181a dampens signals from the cancer-driving NFκB protein pathway in the most aggressive large B-cell lymphomas (DLBCL). By reducing NFκB signaling, miR-181a controls tumor cell proliferation and survival and could be the target of novel therapies. The study was published in the journal Blood.

Penn researchers discover molecular mechanism that underlies common cerebrovascular disease

Cerebral cavernous malformations (CCMs) are clusters of dilated, thin-walled blood vessels in the brain that can cause stroke and seizures, yet exactly how they form is somewhat of a mystery. Now, a team from the Perelman School of Medicine at the University of Pennsylvania has discovered the molecular mechanism that underlies this common cerebrovascular disease. They published their results this week online ahead of print in Nature.

Two recently discovered compounds show promise for treating Ewing sarcoma in children

Two recently discovered compounds have shown promise in preclinical studies for treating Ewing sarcoma, a rare cancer that predominantly affects children and adolescents.

Automated sample-to-answer system could make EVD diagnosis easier

An automated "sample-to-answer" system could provide Ebola virus disease (EVD) diagnosis more quickly and easily than the current standard test, according to research published this week in PLOS Medicine.

DNA sequence features predict genome-wide binding pattern of key protein involved in brain disorders

Researchers from the University of Illinois at Urbana-Champaign and the University of California-Davis are combining in vivo experimentation with computation for highly accurate prediction of the genome-wide binding pattern of a key protein involved in brain disorders.

Deleting microRNA-155 prevents diet-induced obesity in female mice

Researchers at The Ohio State University Wexner Medical Center seeking a way to combat the growing epidemic of obesity have found that deleting microRNA-155 in female mice prevents diet-induced obesity.

Sleep suppresses homeostatic rebalancing of brain activity

Why humans and other animals sleep is one of the remaining deep mysteries of physiology. One prominent theory in neuroscience is that sleep is when the brain replays memories "offline" to better encode them ("memory consolidation").

Sandia engineers aim to develop autonomous device to passively monitor mosquito-borne diseases

Mosquitoes are deadly efficient at spreading disease. Despite vaccines and efforts to eradicate the pesky insects, they continue to infect humans with feared diseases like Zika virus, malaria and West Nile virus.

Kanazawa University researchers identify molecular mechanism that links liver disease and obesity

Kanazawa University researchers find similarities in the impeded signalling between central insulin activity and glucose production in the liver for both obese mice and mice that have had the vagus nerve removed.

Scientists find surprising link between iPS cell reprogramming, blood cell formation and cancer

The ability to reprogram cells has revolutionized stem cell research with major implications for almost all fields of modern biology. A decade ago Shinya Yamanaka described a procedure that revolutionized stem cell biology. Using a genetic trick that introduces a cocktail of four genes into cultured cells from human biopsies, he was able to generate induced pluripotent stem cells (iPS) from mature skin or blood cells

Breast cancer can be more aggressive in obese people

An international team of researchers, with the participation of the University of Granada, has revealed new data on why breast cancer has a higher incidence and is more aggressive in obese people. The reason is that peritumoral fat (the fat around the tumor) facilitates the expansion and invasion of cancer stem cells (CSCs), which are responsible of the onset and growth of the tumor.

Maternal bacterial infections affect fetal brain anatomy and cognitive functioning after birth

St. Jude Children's Research Hospital scientists have discovered how pieces of bacterial cell wall cross the placenta and enter developing neurons, altering fetal brain anatomy and cognitive functioning after birth. The study appears today in the scientific journal Cell Host & Microbe.

Study on DNA scrunching may aid in developing new antimicrobial medicines

A research collaboration that combines novel "big-data" informatics tools with expertise in basic biology has uncovered details of an essential process in life: how a crucial enzyme locates the site on DNA where it begins to direct the synthesis of RNA. This finding may aid in the discovery of new antimicrobial medicines, and the powerful technological approaches developed for this research may shed light on other essential cellular processes.

Over-expression of heme oxygenase-1 enzyme protects the heart from doxorubicin damage

Life-threatening heart damage is an adverse side effect of the cancer drug doxorubicin, damage that also limits the use of newer chemotherapeutic agents such as trastuzumab and imatinib. The ability to protect the heart from these side effects would benefit patients, including cancer survivors who are at risk of developing heart damage years later, and it also could allow safer use of these drugs at higher doses.

Researchers make some progress in determining causes for glioblastoma multiforme

A research team, with the participation of the University of Granada (UGR), has made some progress in determining the causes for glioblastoma multiforme (GBM), one of the most aggressive brain tumors known, to be resistant to the drugs currently used, which is one of the main limitations of its treatment.
