Research shows how protein component of Epstein-Barr virus promotes development of cancer

After an infection with the Epstein-Barr virus (EBV), the virus persists in the body throughout a person's lifetime, usually without causing any symptoms.

LMU study shows crucial role of microRNAs in protecting precursors of neurons

Programmed cell death is an integral part of embryonic development. Exploring the regulation of the process, Ludwig-Maximilians-Universitaet in Munich researchers have shown that so-called microRNAs protect the precursors of neurons from 'precocious' elimination.

Researchers discover earliest-acting protein in C-elegans that plays key role in cell division

Researchers from three U.S. universities have identified, using roundworms, the earliest-acting protein known to duplicate the centriole, a tiny cylinder-shaped structure that is a key component of the machinery that organizes cell division in animals.

Johns Hopkins scientists reveal extra centrosomes can promote tumor formation in mice

When a cell is dividing, two identical structures, called centrosomes, move to opposite sides of the cell to help separate its chromosomes into the new cells.

Protective barrier inside chromosomes helps prevent errors during cell division, study finds

Fresh insights into the structures that contain our genetic material could explain how the body's cells stay healthy.

HSCI researchers use color tagging system to track development of blood stem cells

Harvard Stem Cell Institute (HSCI) researchers have used a colorful, cell-labeling technique to track the development of the blood system and trace the lineage of adult blood cells travelling through the vast networks of veins, arteries, and capillaries back to their parent stem cell in the marrow.

Researchers explore how polymeric nanoparticles can be used to transport quantum dots into cells

Nanoparticles are particles that are smaller than 100 nanometers. They are typically obtained from metals and, because of their tiny size, have unique properties that make them useful for biomedical applications.

Fission yeast could help discover novel cancer drugs

Cancer is a notoriously difficult disease to treat. Not only do a wide variety of cancers exist, requiring specialized treatments for each type, but cancer cells within an individual can morph and render previously potent therapeutics ineffective.

Scientists discover key molecule that drives regeneration in planarian stem cells

Many living creatures possess exceptional abilities that set them apart from other species. Cheetahs can run up to 60 miles per hour; ants can lift 100 times their body weight; flatworms can regrow amputated body parts.

Study provides insight into why individual mycobacteria respond differently to antibiotics

Tuberculosis is one of the most common infectious diseases in the world, infecting almost 10 million people each year. Treating the disease can be challenging and requires a combination of multiple antibiotics delivered over several months.

Study could offer new ways to enhance cancer immunotherapy

When an immune T cell divides into two daughter cells, the activity of an enzyme called mTORC1, which controls protein production, splits unevenly between the progeny, producing two cells with different properties.

Study links proteins involved in cell division to insulin signaling

Proteins that play key roles in the timing of cell division also moonlight in regulating blood sugar levels, UT Southwestern Medical Center researchers have found.

Researchers determine how Ki-67 protein disperses chromosomes in dividing cells

Billions of your cells divide every day. Cell division fuels growth and also replaces short-lived cells in some organs, like your skin, blood, and gut.

Penn researchers help identify unique characteristics of reserve stem cells

Adult stem cells represent a sort of blank clay from which a myriad of different cell and tissue types are molded and as such are of critical importance to health, aging and disease.

Mayo study finds mechanism by which Pten safeguards against tumor formation

Pten (short for phosphatase and tensin homolog) is a tumor suppressor that is defective in about 20-25 percent of all patients with cancers. Mayo Clinic researchers now have discovered that Pten safeguards against tumor formation by keeping chromosome numbers intact when a cell splits into two daughter cells.

Cryptococcus research: an interview with Associate Professor Kirsten Nielsen

Cryptococcus is a fungus found in the environment throughout the world that is able to cause disease in humans. While most fungal pathogens don’t receive as much press as their bacterial or viral counterparts, they can be just as deadly.

Nanoparticles of ultrapure silicon act as luminescent markers in early diagnosis of cancer

The group of Russian and French researchers, with the participation of scientists from the Lomonosov Moscow State University, has succeeded to synthesize nanoparticles of ultrapure silicon, which exhibited the property of efficient photoluminescence, i.e., secondary light emission after photoexcitation.

Key protein involved in mitosis helps prevent abnormal distribution of chromosomes

A tension-sensitive "fail safe" protein helps make sure that when our cells divide the two resulting cells inherit the normal number of chromosomes, researchers from the University of Washington and the Fred Hutchinson Cancer Research Center report today, May 5, in the journal Cell.

LJI study could provide important target for autoimmune disease interventions

Follicular helper T cells (Tfh cells), a rare type of T cells, are indispensable for the maturation of antibody-producing B cells. They promote the proliferation of B cells that produce highly selective antibodies against invading pathogens while weeding out those that generate potentially harmful ones.

Hippo signaling pathway controls phases of quiescence in fruit fly central nervous system

Neural stem cells are responsible for the formation of differentiated daughter cells in the developing brain. If no new cells are needed, the stem cells may enter a resting phase called quiescence. Biologists at Johannes Gutenberg University Mainz have now discovered that the phases of quiescence in the Drosophila fruit fly central nervous system are controlled by the Hippo signaling pathway. Drosophila serves as a model organism that helps geneticists to decode the molecular fundamentals of cellular biology and unravel mechanisms that are conserved in human beings and other vertebrates.
