‘Terminator’ protein halts tumorigenesis

Essential processes in mammalian cells are controlled by proteins called transcription factors. For example, the transcription factor HIF-1 is triggered by a low-oxygen situation to cause the cell to adapt to decreased oxygen.

Study uncovers why developing nerve cells take a wrong turn

A group of scientists from CECAD, the Cluster of Excellence 'Cellular Stress Responses in Aging-Associated Diseases,' have found a mechanism by which neurodevelopmental diseases concerning neurons can be explained: The loss of a certain enzyme, UBE2K, impeded the differentiation of stem cells by silencing the expression of genes important for neuronal differentiation and, therefore, the development and generation of neurons.

Researchers identify key gene essential for leukemia stem cells' survival

Acute myeloid leukemia (AML) is one of the most common forms of blood cancer among adults and is associated with a low survival rate, and leads to the inhibition of normal blood formation.

Research team discovers proteins that regulate interorganelle communication

Korea Brain Research Institute (KBRI headed by Suh Pann-ghill) announced on the 2nd that the joint research team of KBRI (team led by Dr. Mun Ji-young), Seoul National University, and Pohang University of Science and Technology discovered the proteins that engage in the formation of MAM, which is the cellular signaling hub.

ETH researchers uncover a complex plant-bacteria interaction

Plants need nitrogen in the form of ammonium if they are to grow. In the case of a great many cultivated plants, farmers are obliged to spread this ammonium on their fields as fertilizer.

Review reveals exceptions to the purported rules of sex chromosome evolution theory

For nearly a century, biologists have modeled the evolution of sex chromosomes--the genetic instructions that primarily determine whether an individual will develop into a male or female (or a certain mating type)--resulting in an impressive theoretical framework.

Bacteria that live in soil and on people have widespread antibiotic-destroying genes

The latest generation of tetracyclines - a class of powerful, first-line antibiotics - was designed to thwart the two most common ways bacteria resist such drugs.

Researchers unravel mechanisms behind organ-specific elimination of chromosomes in plants

Whilst we often think of somatic cells in an organism as containing the same DNA and therefore the same number of chromosomes, it is surprising, how often this is not the case.

Dramatic increase in immune cells in mouse lungs after birth may help protect against infections

An explosion in the number and types of immune cells in the lungs of newborn mice likely helps them adapt to breathing and protects them from infection, says a new study published today in eLife.

Scientists decode ancient DNA extracted from Dead Sea Scrolls

An interdisciplinary team from Tel Aviv University, led by Prof. Oded Rechavi of TAU's George S. Wise Faculty of Life Sciences, Prof. Noam Mizrahi of TAU's Department of Biblical Studies, in collaboration with Prof. Mattias Jakobsson of Uppsala University in Sweden, the Israel Antiquities Authority and Prof. Christopher E. Mason of Weill Cornell Medicine, has successfully decoded ancient DNA extracted from the animal skins on which the Dead Sea Scrolls were written.

Study identifies key protein required for optimal immune responses to cancer

A new study led by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Solove Research Institute has identified a protein within certain immune cells that is required for optimal immune responses to cancer.

Researchers create 3D fluorescence and phase imaging of living cells based on digital holography

A research group led by Kobe University's Professor MATOBA Osamu (Organization for Advanced and Integrated Research) has successfully created 3D fluorescence and phase imaging of living cells based on digital holography.

Research suggests new possibility for how glucose transporters operate

Some of the most essential processes on the planet involves water and energy entering and leaving cells.

Scientists uncover a moving target in small cell lung tumors

Lung cancers account for approximately 25 percent of all cancer deaths. Even among those who do not smoke, 1 in 15 men and 1 in 17 women are expected to develop lung cancer in their lifetime, according to the American Cancer Society.

A remote optical stimulation for neural cells

A team led by researchers at Carnegie Mellon University has created a new technology that enhances scientists' ability to communicate with neural cells using light.

Stem cell model sheds new light on neurodegeneration process

A new study published today in Neuron led by The New York Stem Cell Foundation Research Institute's Valentina Fossati, Ph.D., creates astrocytes - an integral support cell in the brain - from stem cells and shows that in disease-like environments, these normally helpful cells can turn into neuron-killers.
