Thinking afresh about how cells respond to stress

Just like people, cells get stressed too. A sudden drop in oxygen, overheating, or toxins can trigger a cascade of molecular changes that lead cells to stop growing, produce stress-protective factors, and form stress granules—proteins ...

Researchers light cells using nanosheets for cancer treatment

Scientists in the Department of Biomedical Engineering at Texas A&M University are developing new ways to advance the field of regenerative medicine and cancer treatment. They are developing a 2-D nanosheet that is 1,000 ...

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 ...

Widespread misinterpretation of gene expression data

Reproducibility is a major challenge in experimental biology, and with the increasing complexity of data generated by genomic-scale techniques this concern is immensely amplified. RNA-seq, one of the most widely used methods ...

Intracellular transport in 3-D

Ludwig Maximilian University researchers have visualized the complex interplay between protein synthesis, transport and modification.
