New technique for IDing proteins secreted by cells developed

(Phys.org)—Researchers from North Carolina State University have developed a new technique to identify the proteins secreted by a cell. The new approach should help researchers collect precise data on cell biology, which ...

Oversized fat droplets: Too much of a good thing

As the national waistline expands, so do pools of intra-cellular fat known as lipid droplets. Although most of us wish our lipid droplets would vanish, they represent a cellular paradox: on the one hand droplets play beneficial ...

Self-digestion as a means of survival

In times of starvation, cells tighten their belts: they start to digest their own proteins and cellular organs. The process - known as autophagy - takes place in special organelles called autophagosomes. It is a strategy ...

'Birth control' for centrioles

Like DNA, centrioles need to duplicate only once per cell cycle. Rogers et al. uncover a long-sought mechanism that limits centriole copying, showing that it depends on the timely demolition of a protein that spurs the organelles' ...

Measuring the temperature inside cells

Organelles inside cells constantly serve specific functions in the same way that individual departments handle certain tasks in an organization. Cellular processes alter the amount of heat organelles generate, but it is not ...

Artificial organelles based on hybrid protein nanoparticles

Compartmentalization is one of the main strategies by which nature allows for control over many biological processes. For the proper functioning of living cells, organelles, small compartments within the cell, are essential. ...
