Cellular stress causes cancer cell chemoresistance

There is a broad range of mechanisms associated with chemoresistance, many of which to date are only poorly understood. The so-called cellular stress response—a set of genetic programs that enable the cells to survive under ...

Catch and release: Collagen-mediated control of PEDF availability

Cells are like tiny self-contained machines that are constantly fine-tuned in response to both internal and external signals. Some of these signals are induced by extracellular ligands, specialized proteins that bind to specific ...

Same genes, same conditions, different transport

The bacterium Lactococcus lactis, which plays an important role in the dairy industry, is unable to produce the amino acid methionine and has to rely on uptake from the environment. To do this, the bacteria have two systems ...

Variability in the molecules of life

How variable are gene transcripts and proteins, the molecules of life, across the tissues and organs of the human body? Furthermore, how variable are they within the same tissue type from different people? Understanding this ...

Dundee lab solves HOIL-1 mystery

The mysterious function of a key protein has been revealed following a breakthrough by University of Dundee scientists.

Engineers make injectable tissues a reality

A simple injection that can help regrow damaged tissue has long been the dream of physicians and patients alike. A new study from researchers at UBC Okanagan moves that dream closer to reality with a device that makes encapsulating ...

A better way to measure cell survival

Measuring the toxic effects of chemical compounds on different types of cells is critical for developing cancer drugs, which must be able to kill their target cells. Analyzing cell survival is also an important task in fields ...
