Cell survival protein research reveals surprise structure

Researchers from the Walter and Eliza Hall Institute have found a structural surprise in a type of protein that encourages cell survival, raising interesting questions about how the proteins function to influence programmed ...

Mitochondrial cooperatives

Mitochondria, the organelles that supply the cell with energy, are highly dynamic and can link up to form complex tubular networks. A new study shows that this response can transiently compensate for a shortfall in energy ...

Newly discovered enzyme is 'firing pin' for plant immunity

Just like humans, plants have an immune system that helps them fight off infections. Plant immunity has some important differences: they don't make antibodies and can't fight off the same bug more quickly months or years ...

New strategy directly activates cellular 'death protein'

Researchers at Dana-Farber/Children's Hospital Cancer Center have devised a strategy to directly activate a natural "death" protein, triggering the self-destruction of cells. They say the development could represent a new ...

Scientists program proteins to pair exactly

Proteins have now been designed in the lab to zip together in much the same way that DNA molecules zip up to form a double helix. The technique, whose development was led by University of Washington School of Medicine scientists, ...

Cell death occurs in the same way in plants, animals and humans

Research has previously assumed that animals and plants developed different genetic programs for cell death. Now an international constellation of research teams, including one at the Swedish University of Agricultural Sciences, ...

Genetic mutation causes ataxia in humans and dogs

Cerebellar ataxia is a condition of the cerebellum that causes an inability to coordinate muscle movements. A study publishing June 16 in Cell Reports now describes a new genetic mutation as an additional cause of ataxia ...

New cobalt complex triggers ferroptosis in cancer cells

In programmed cell death, certain signaling molecules initiate a kind of suicide program to cause cells to die in a controlled manner. This is an essential step to eliminate damaged cells or to control the number of cells ...

Researchers unveil DNA-guided 3-D printing of human tissue

A UCSF-led team has developed a technique to build tiny models of human tissues, called organoids, more precisely than ever before using a process that turns human cells into a biological equivalent of LEGO bricks. These ...
