Extracellular vesicles derived from mesenchymal stem cells mediate extracellular matrix remodeling in osteoarthritis through the transport of microRNA-29a

BACKGROUNDKnee osteoarthritis (KOA) is a common orthopedic condition with an uncertain etiology, possibly involving genetics and biomechanics. Factors like changes in chondrocyte microenvironment, oxidative stress, inflammation, and immune

RESEARCH ALERT: Stopping Multiple Myeloma

Cedars-Sinai Cancer investigators have discovered a protein expressed on multiple myeloma cancer cells that drives disease growth and development. The new study found that blocking part of the protein’s unique signaling pathway stops myeloma growth in culture and in laboratory mice.

Oral Pill Improves Care of Patients with Bone Marrow Cancer: Study

Momelotinib, an oral pill taken once a day, significantly improved outcomes of patients treated for myelofibrosis (MF), a rare but fatal bone marrow cancer, researchers reported June 7. Ruben Mesa, MD, FACP, executive director of the Mays Cancer Center, home to UT Health San Antonio MD Anderson Cancer Center, presented results of the MOMENTUM phase 3 randomized study, which evaluated momelotinib against a second medication, danazol, in symptomatic and anemic MF patients previously treated with standard-of-care JAK inhibitor therapy.

Study: Obesity raises the risk of gum disease by inflating growth of bone-destroying cells

Chronic inflammation caused by obesity may trigger the development of cells that break down bone tissue, including the bone that holds teeth in place, according to new University at Buffalo research that sought to improve understanding of the connection between obesity and gum disease.

Researchers Identify Mechanism By Which Exercise Strengthens Bones And Immunity

Scientists at the Children’s Medical Center Research Institute at UT Southwestern (CRI) have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced. The study, published in Nature, also shows that movement-induced stimulation is required for the maintenance of this niche, as well as the bone and immune-forming cells that it contains. Together, these findings identify a new way that exercise strengthens bones and immune function.

Scientists Engineer New Cancer Immunotherapy to Train Immune System in Cancer Fight

A groundbreaking new type of cancer immunotherapy developed at the Icahn School of Medicine at Mount Sinai trains the innate immune system to help it eliminate tumor cells through the use of nanobiologics, tiny materials bioengineered from natural molecules that are paired with a therapeutic component, according to a study published in Cell in October.

Mouse Study Shows Spinal Cord Injury Causes Bone Marrow Failure Syndrome

Researchers at The Ohio State University Wexner Medical Center and College of Medicine found that spinal cord injuries in mice cause an acquired bone marrow failure syndrome that may contribute to chronic immune dysfunction.
