New Technique Identifies a Gene that Drives Clonal Expansion of Abnormal Cells

An international coalition of biomedical researchers co-led by Alexander Bick, MD, PhD, at Vanderbilt University Medical Center has determined a new way to measure the growth rate of precancerous clones of blood stem cells that one day could help doctors lower their patients' risk of blood cancer.

B lymphocytes stimulate the in-demand production of innate immune cells during infection

An SOS signals a call for immediate action during an emergency to request a need for protection. The immune system, a network of defense mechanisms, enhances protection to recover the body's internal stability.

Role of clonal hematopoiesis as a broad driver of atherosclerosis

A group at the Centro Nacional de Investigaciones Cardiovasculares (CNIC), collaborating with institutions in the USA, has shown that acquired mutations in the gene encoding the protein p53 contribute to the onset of atherosclerotic cardiovascular disease.

Molecular regulation underlying emergency hematopoiesis uncovered

If the body’s emergency hematopoiesis program activates, it signifies an alert state of the immune system and serves two functions: In comparison to “normal mode” hematopoiesis, the emergency program results in enhanced replacement of immune cells consumed during infections or inflammations.

Spaceflight increases the risk of developing cancer and heart disease

A groundbreaking study from the Icahn School of Medicine at Mount Sinai found that astronauts are more likely to experience mutations that could be connected to spaceflight and increase their lifetime risk of acquiring cancer and heart disease.

Mitochondrial DNA plays a crucial role in inflammation, study finds

Mitochondria are generally known as the powerhouse of the cell, however, growing research indicates that they may potentially be involved in inflammation.

Biochemical signals sent from cell to cell play a key role in deciding their fate

Scientists have found a way to prove that biochemical signals sent from cell to cell play an important role in determining how those cells develop.

Study sheds light on blood and immune systems development in prenatal bone marrow

Researchers carried out the first extensive investigation of the formation of the blood and immune systems in the prenatal bone marrow.

Scientists reveal health benefits of clonal hematopoiesis in allogeneic transplants

Clonal hematopoiesis (CH) is a recently identified condition in which mutations associated with blood cancers are detected in the blood of some healthy, usually older, individuals who don't have cancer. People with CH, while asymptomatic, have an elevated risk of developing blood cancers and other negative health outcomes, including heart attacks and strokes.

Somatic mutation acts as natural gene therapy in patients with GATA2 deficiency

Researchers affiliated with the Center for Cell-Based Therapy (CTC) in Ribeirão Preto, Brazil, have identified for the first time a non-hereditary mutation in blood cells from a patient with GATA2 deficiency, a rare autosomal disease caused by inherited mutations in the gene that encodes GATA-binding protein 2 (GATA2).

Unrelated mutations can lead to false positive results in men with advanced prostate cancer

Unrelated mutations, when present in the blood, can lead to false positive results in men with advanced prostate cancer who are undergoing liquid biopsies.

MIT engineers develop a method to turn off specific genes in bone marrow cells

Using specialized nanoparticles, MIT engineers have developed a way to turn off specific genes in cells of the bone marrow, which play an important role in producing blood cells.
