Stem cell discovery could open the door to new approach for bone marrow transplantation

Mount Sinai researchers have discovered a way to enhance the potency of blood-forming stem cells, potentially opening the door to a new approach for bone marrow transplantation, according to a study being published on February 27 in Cell Stem Cell.

Study reveals how cells remove misfolded proteins from tissues

Researchers in Japan have identified a new quality control system that allows cells to remove damaged and potentially toxic proteins from their surroundings.

Defective ATP13A2 gene can lead to Parkinson's disease, shows study

Biomedical scientists at KU Leuven have discovered that a defect in the ATP13A2 gene causes cell death by disrupting the cellular transport of polyamines.

Study suggests prenatal origin for ‘young’ Parkinson’s disease

A new study published in the journal Nature Medicine on January 2020 suggests that Parkinson’s disease developing before the age of 50 years could be due to an abnormality in certain brain cells that remains dormant until the age of onset of the disease. It also indicates the potential usefulness of a specific drug to prevent this by correcting the brain cell disorder.

Parkinson's disease may affect brain cells before birth

People who develop Parkinson's disease before age 50 may have been born with disordered brain cells that went undetected for decades, according to new Cedars-Sinai research. The research points to a drug that potentially might help correct these disease processes.

Scientists discover why the cells need acidic lysosomes

Just like the body contains lungs, liver, and lymph nodes, so does each of the body's cells contain tiny specialized organs. Perhaps most peculiar among them are lysosomes--bubble-like sacks that act as part recycling bin, part stomach.

Novel drug can simultaneously help diagnose, treat gastric cancer

A novel drug, named "FerriIridium", can simultaneously help diagnose and treat gastric cancer. The initially weakly active precursor (prodrug), based on an iridium-containing compound, is selectively activated only after reaching the interior of a tumor cell. This is possible because of the higher amount of iron present there, report scientists in the journal Angewandte Chemie.

Certain enzymes implicated in diseases like cancer also destroy each other

Like motley bandits, certain enzymes implicated in cancer and other diseases also annihilate each other. A new study reveals details of their mutual foils in the hopes that these behaviors can be leveraged to fight the enzymes' disease potential.

Enzymes that cannibalize each other and promote cancer

A new study to be published this week in the journal The Proceedings of the National Academy of Sciences in the week of January 20, 2020. shows that certain human enzymes play dual roles in health and disease. Not only do they promote the occurrence of cancer and some other illnesses, they also eliminate one another rather like cannibals. The researchers hope this behaviour can be exploited to prevent these enzymes from causing human disease.

New nanotech technique fights advanced-stage sepsis

Scientists have found a novel approach using nanotechnology that can fight late-stage sepsis.

Researchers develop new way to fight late-stage sepsis

Researchers have developed a way to prop up a struggling immune system to enable its fight against sepsis, a deadly condition resulting from the body's extreme reaction to infection.

RNA hitches lysosome rides to make proteins far away from the nucleus

Proteins inside a cell are often made at the site where they are used, rather than being shipped long distances. This is so with nerve cells which have long cell extensions in the form of axons and dendrites, up to four feet long in some case

Researchers discover how cancer cells can trigger chronic muscle wasting condition

A solid tumor can cause muscle cells in the body to self-destruct. Many cancer patients die from the consequences. Now researchers are discovering more about how cancer cells in a tumor can take control of muscle cell wasting and trigger a chronic, serious condition.

Cancer cells survive chemotherapy by eating their neighboring tumor cells

Researchers from the Tulane University School of Medicine have discovered that some cancer cells survive chemotherapy by eating their neighboring tumor cells.

Researchers discover potential of antihistamines that cause death of leukemic stem cells

Ruth M. Risueño leads the Leukaemic Stem Cell group of the Josep Carreras Leukaemia Research Institute. This group investigates Acute Myeloid Leukemia and the cell population responsible for the disease spreading, persisting, and if it has been treated and overcome, reappear.

Researchers study biological risk potential of nanoparticles

Nanoparticles are smaller than five nanometres - a nanometre being one millionth of a millimetre - which corresponds approximately to the size of macromolecules. Such tiny particles are very easily absorbed in body cells.

Researchers identify new transmembrane protein as chloride ion channel

In the human body the salt content of cells and their surrounding is regulated by sophisticated transport systems.

New research suggests another possible mechanism for Alzheimer’s

Neurofibrillary plaques and tau protein are among the most widely known pathological entities characterizing Alzheimer’s disease (AD), but new research at the University of California, Riverside, has come up with another plausible explanation for this debilitating disorder.

Researchers identify alternate chemistry that could account for Alzheimer's pathologies

Alzheimer's disease, the most common cause of dementia among the elderly, is characterized by plaques and tangles in the brain, with most efforts at finding a cure focused on these abnormal structures.

Cascade aggravates hereditary storage diseases

In rare, hereditary storage diseases such as Sandhoff's disease or Tay-Sachs syndrome, the metabolic waste from accumulating gangliosides cannot be properly disposed of in the nerve cells because important enzymes are missing.
