Study shows how osteocalcin plays a significant role in bone strength

A new study from engineering researchers at Rensselaer Polytechnic Institute shows, for the first time, how the little-understood protein osteocalcin plays a significant role in the strength of our bones. The findings could lead to new strategies and therapeutics for fighting osteoporosis and lowering the risk of bone fracture.

New coronavirus can infect cells from humans and bats alike

The SARS epidemic of 2002-2003 was short-lived, but a novel type of human coronavirus that is alarming public health authorities can infect cells from humans and bats alike, a fact that could make the animals a continuing source of infection, according to a study to be published in in mBio-, the online open-access journal of the American Society for Microbiology, on December 11.

Study finds high serum galectin-1 levels in Hodgkin lymphoma patients

Blood levels of an immunity-related protein, galectin-1, in patients with newly diagnosed Hodgkin lymphoma reflected the extent of their cancer and correlated with other predictors of outcome, scientists reported at the American Society of Hematology annual meeting.

Pfizer's PD0325901 experimental drug blocks untreatable NF1 tumors

Researchers conducting a preclinical study in mice successfully used targeted molecular therapy to block mostly untreatable nerve tumors that develop in people with the genetic disorder Neurofibromatosis 1 (NF1).

Bolstering extracellulal matrix prevents skin aging

As we get older, the trillions of cells in our body do too. And like us, they become less resilient and able to weather the stress of everyday life. Our skin especially tells the tale of what's happening throughout our bodies.

Weill Cornell research team develops new experimental drug therapy to target DLBCL

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin's lymphoma and the seventh most frequently diagnosed cancer. The most chemotherapy resistant form of DLBCL, called activated B-cell - DLBCL (ABC-DLBCL), remains a major therapeutic challenge.

Lack of TDP-43 protein can lead to frontotemporal dementia/ALS

Researchers at Mayo Clinic in Florida have uncovered a toxic cellular process by which a protein that maintains the health of neurons becomes deficient and can lead to dementia.

Transplanting spermatogonial stem cells could restore fertility in male cancer patients

Radiation and chemotherapy can pack a powerful punch against all kinds of cancers. Those who survive, however, are often left with bad news: Their treatments have rendered them infertile.

FAC PET identifies liposarcoma tumors that are sensitive to chemotherapy

Liposarcoma, the most common type of sarcoma, is an often lethal form of cancer that develops in fat cells. It is particularly deadly, in part, because the tumors are not consistently visible with positron emission tomography (PET) scans that use a common probe called FDG and because they frequently do not respond to chemotherapy.

GSK, Fred Hutch to develop therapeutics against facioscapulohumeral muscular dystrophy

Fred Hutchinson Cancer Research Center and GlaxoSmithKline PLC (GSK) today announced a partnership to develop therapeutics to treat an inherited form of muscular dystrophy.

Acetylon announces results from selective HDAC 1/2 inhibitor preclinical study on SCD and bT

Acetylon Pharmaceuticals Inc., a leader in targeted epigenetic drug discovery and development for enhanced therapeutic outcomes, today announced results from a preclinical study of a selective histone deacetylase (HDAC) 1/2 inhibitor for the treatment of sickle cell disease (SCD) and beta-thalassemia (bT) at the 54th Annual Meeting of the American Society of Hematology (ASH), taking place in Atlanta, Georgia.

UNM study to understand why and how DNA repair mechanisms go awry in cancer cells

DNA, like houses and cars, needs ongoing maintenance. Rays of ultraviolet sunlight, chemical pollutants and normal biochemical processes in the cell can damage it. Cells routinely repair this damage before making proteins or copying DNA for cell division. The repairs are remarkably accurate in normal cells but cancer cells make far more mistakes in fixing their DNA.

Combination of diagnostic tests can predict conversion from MCI to Alzheimer's

A combination of diagnostic tests, including imaging and cerebrospinal fluid biomarkers can improve prediction of conversion from mild cognitive impairment (MCI) to Alzheimer's disease, according to a new study published online in the journal Radiology.

Orientation of antibody binding to bacteria can mean life or death to the bug

The orientation of antibody binding to bacteria can mean life or death to the bug, according to a study published in The Journal of Experimental Medicine on December 10th. These findings may help explain why these bacteria cause millions of localized infections, but more serious, systemic blood infections are rare.

Alpha arrestins may play a role in cell signaling that is crucial to new drug development

A newly found understanding of receptor signaling may have revealed a better way to design drugs. A study from Nationwide Children's Hospital suggests that a newly identified group of proteins, alpha arrestins, may play a role in cell signaling that is crucial to new drug development.

Auditory systems differ between sexes in sparrows depending on the season

Auditory systems differ between sexes in sparrows depending on the season, a Georgia State University neuroscientist has found. The work adds to our knowledge of how the parts of the nervous system, including that of humans, are able to change.
