C-Path and Japan's PMDA join forces on first-of-its-kind biomarker project

Critical Path Institute announced today that a formal consultation between its Predictive Safety Testing Consortium and Japan's Pharmaceuticals and Medical Devices Agency has resulted in an agreement on a first-of-its-kind approach to compare the levels of eight novel urinary kidney safety biomarkers in healthy Japanese volunteers to data collected on these same biomarkers in healthy Western volunteers in a bridging study.

Researchers show how mechanical stress affects bone development

Researchers at Okayama University show how mechanical stress at very early stages of bone development alters expression pattern of the non-collagenous matrix responsible for biological property of the bone.

Study shows new emerging role of osteopontin in HCV-related hepatocellular carcinoma

Hepatitis C virus (HCV) infection is the major cause of hepatocellular carcinoma (HCC) and was estimated to be responsible for 745,000 deaths in 2012.

Researchers develop diagnostic test to determine risk of developing malignant breast cancer

Currently, with a pre-malignant breast cancer diagnosis from a biopsy, there are three options: observation, chemoprevention or surgery, all of which require a patient to make decisions while operating from a place of fear and unknown outcomes.

MIT researchers devise way to help blood cells regenerate after radiation therapy

Patients with blood cancers such as leukemia and lymphoma are often treated by irradiating their bone marrow to destroy the diseased cells. After the treatment, patients are vulnerable to infection and fatigue until new blood cells grow back.

Scientists analyze nanostructure of chicken eggshells

The results of a study recently published in the prestigious international journal Science Advances have enabled researchers to better understand the role of eggshells in embryo development and hatching.

Scientists propose rejuvenating bone marrow stem cell niche to boost immunity, fend off cancers

As people get older so do the hematopoietic stem cells (HSCs) that form their blood, creating an increased risk for compromised immunity and certain blood cancers. Now researchers are reporting in the scientific journal that the bone marrow niche where HSC's form also ages, contributing to the problem.

Researchers reveal mechanism for side effects of drug used for treating hematological malignancies

A team of Japanese researchers revealed the mechanism for side effects such as fever and bone pain caused by G-CSF, which is widely used for peripheral blood hematopoietic stem cell harvesting (PBSCH).

Study reveals promising strategy against bladder cancer metastasis

The popular kids' card game "Exploding Kittens" teaches a concept critical to cancer science: When a player plays a "Nope" card, the subsequent player may lay another "Nope", thus creating a double-negative that becomes a positive, allowing the initial action to proceed.

Researchers explore molecular mechanisms through which lead exposure may affect neural stem cells

Researchers have identified a potential molecular mechanism through which lead, a pervasive environmental toxin, may harm neural stem cells and neurodevelopment in children.

Specific urine proteins may be indicators of acute kidney injury in preterm infants

A new study indicates that several proteins are excreted differently in preterm infants with kidney injury compared with those with healthy kidneys.

Removing immunomodulatory protein improves symptoms of muscular dystrophy in mice

Removing an immunomodulatory protein called osteopontin improves the symptoms of mice with muscular dystrophy by changing the type of macrophages acting on damaged muscle tissue, according to a paper published in The Journal of Cell Biology.

"Self-fitting" material precisely fills bone defects and acts as scaffold for new bone growth

Injuries, birth defects (such as cleft palates) or surgery to remove a tumor can create gaps in bone that are too large to heal naturally. And when they occur in the head, face or jaw, these bone defects can dramatically alter a person's appearance.

FAK inhibitors prevent ovarian cancer progression

A team of scientists, led by principal investigator David D. Schlaepfer, PhD, professor in the Department of Reproductive Medicine at the University of California, San Diego School of Medicine report that small molecule inhibitors to a protein called focal adhesion kinase (FAK) selectively prevent the growth of ovarian cancer cells as tumor spheroids.

Protein helps leukemia cells avoid effects of chemotherapy by appearing dormant

A new study on how the progression of acute lymphocytic leukemia is influenced by the bone marrow environment has demonstrated for the first time that targeting a specialized protein known as osteopontin may be an effective strategy to increase the efficacy of chemotherapy in patients with this type of blood cancer.

Osteopontin plays a role in X-linked hypophosphatemia

Diagnosed in toddlers, X-linked hypophosphatemia (XLH) is the most common form of heritable rickets, in which soft bones bend and deform, and tooth abscesses develop because infections penetrate soft teeth that are not properly calcified. Researchers at McGill University and the Federal University of Sao Paulo have identified that osteopontin, a major bone and tooth substrate protein, plays a role in XLH. Their discovery may pave the way to effectively treating this rare disease.

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.

Liver x receptor plays an important role in diabetic nephropathy

Researchers have discovered a new therapeutic target for diabetic nephropathy, the leading cause of kidney failure.

Biomarkers predict benefit of targeted therapy in metastatic renal-cell cancer

In metastatic renal-cell cancer, the level of cytokines and angiogenic factors identify those patients with an aggressive disease course who derive the greatest benefit from treatment with the molecular-targeted therapy pazopanib, a retrospective analysis of clinical trials shows.

PRDM16 transcription co-factor plays a critical role in development of embryonic palate

In the United States, a baby is born with a facial cleft every hour, of every day of the year! Such birth defects result from both gene mutations and environmental insults. PRDM16 is a transcription factor originally described as being aberrantly activated in specific types of leukemia's, and more recently as a master regulator of brown adipose tissue differentiation.
