B-cell substances may play a role in MS progression

Wayne State University School of Medicine researchers, working with colleagues in Canada, have found that one or more substances produced by a type of immune cell in people with multiple sclerosis (MS) may play a role in the disease's progression. The finding could lead to new targeted therapies for MS treatment.

Possible molecular link between circadian rhythm disturbances and increased inflammatory response

Scientists have known for some time that throwing off the body's circadian rhythm can negatively affect body chemistry. In fact, workers whose sleep-wake cycles are disrupted by night shifts are more susceptible to chronic inflammatory diseases such as diabetes, obesity and cancer.

Scientists discover critical molecular switch that regulates autophagy

The body has a built-in system known as autophagy, or 'self-eating,' that controls how cells live or die. Deregulation of autophagy is linked to the development of human diseases, including neural degeneration and cancer.

Three papers focus on nucleosomes and may help uncover the rules governing gene transcription

A trio of groundbreaking publications from researchers in Northwestern University's Physical Sciences-Oncology Center (PS-OC) report important methodological advances that will enable a better understanding of how gene expression is regulated, both in normal cells and in cancer cells. This knowledge could lead to the development of more effective therapeutic agents to treat cancer patients.

'Global brain connectivity' explains 10% of variance in individual intelligence

When it comes to intelligence, what factors distinguish the brains of the exceptionally smart from those of average humans? As science has long suspected, overall brain size matters somewhat, accounting for about 6.7 percent of individual variation in intelligence. More recent research has pinpointed the brain's lateral prefrontal cortex, a region just behind the temple, as a critical hub for high-level mental processing, with activity levels there predicting another 5 percent of variation in individual intelligence.

Researchers discover genetic process that can restore function to a CF defective protein

Researchers at the University of Iowa Carver College of Medicine have discovered a genetic process that can restore function to a defective protein, which is the most common cause of cystic fibrosis (CF).

Diacetyl intensifies damaging effects of beta-amyloid proteins linked to Alzheimer's

A new study raises concern about chronic exposure of workers in industry to a food flavoring ingredient used to produce the distinctive buttery flavor and aroma of microwave popcorn, margarines, snack foods, candy, baked goods, pet foods and other products.

CAP publishes revised version of molecular pathology checklist with dedicated section on NGS

The College of American Pathologists (CAP) published a revised version of its molecular pathology checklist with a dedicated section on next generation sequencing (NGS) as part of the new edition of the CAP Laboratory Accreditation Program checklists released July 31, 2012.

Researchers unlock genetic secrets of peripheral T-cell lymphomas

Researchers at Mayo Clinic have completed the world's first genome-wide sequencing analysis of peripheral T-cell lymphomas, unlocking the genetic secrets of this poorly understood and highly aggressive cancer of the immune system.

MLK3 protein critical driver of breast cancer cell migration and invasion

By identifying a key protein that tells certain breast cancer cells when and how to move, researchers at Michigan State University hope to better understand the process by which breast cancer spreads, or metastasizes.

Patients with multiple colorectal adenomas may carry germline mutations in APC or MUTYH genes

Among patients with multiple colorectal polyps, the prevalence of certain gene mutations varied considerably by polyp count, according to a study in the August 1 issue of JAMA.

HIV people with high CD4 counts could work more hours per week

In a first-of-its-kind health campaign in Uganda, researchers from the University of North Carolina at Chapel Hill show that adults with HIV who had less severe infections could work more hours per week, and their children were more likely to be enrolled in school.

Link between skeletal development and Fraser syndrome deafness in mammals

Using mutant zebra fish, researchers studying the earliest formation of cartilage of the mouth believe they may have gotten a look at a mechanism involved in a genetic defect linked to Fraser syndrome deafness in humans.

Scientists identify biological mechanism that may be responsible for icy extremities

Cold feet-those chilly appendages that plague many people in the winter and an unlucky few all year round-can be the bane of existence for singles and couples alike. In a new study, scientists led by Selvi C. Jeyaraj of the Research Institute at Nationwide Children's Hospital have identified a biological mechanism that may be responsible for icy extremities: an interaction between a series of molecules and receptors on smooth muscle cells that line the skin's tiny blood vessels.

Study explains why patients with sinusitis sneeze more often than others

Who would have thought that our noses and Microsoft Windows' infamous blue screen of death could have something in common? But that's the case being made by a new research report appearing online in The FASEB Journal.

Flightless molecule may help control spread of cancer from one tissue to another

Thanks to the "flightless" molecule, the spread of cancer from one tissue to another may one day be grounded. In a new report published in the August 2012 print issue of The FASEB Journal, laboratory experiments show that "flightless" (named after its effects on fruit flies) increases the "stickiness" that causes cells, including cancer cells, to attach to underlying tissue, which in turn, slows their movement throughout the body.

Miami Project to Cure Paralysis receives FDA permission to begin Phase 1 trial

The Miami Project to Cure Paralysis, a Center of Excellence at the University of Miami Miller School of Medicine, has received permission from the Food and Drug Administration to begin a revolutionary Phase 1 clinical trial to evaluate the safety of transplanting human Schwann cells to treat patients with recent spinal cord injuries.

Scientists decode stability blueprint of rhomboid enzyme

Johns Hopkins scientists have decoded for the first time the "stability blueprint" of an enzyme that resides in a cell's membrane, mapping which parts of the enzyme are important for its shape and function.

Orc1 mutations may explain pathology in manifestations of Meier-Gorlin syndrome

Research published Aug. 1 by scientists at Cold Spring Harbor Laboratory (CSHL) links gene mutations found in some patients with Meier-Gorlin syndrome (MGS) with specific cellular dysfunctions that are thought to give rise to a particularly extreme version of dwarfism, small brain size, and other manifestations of abnormal growth which generally characterize that rare condition.
