Microscopy opens doors for studying neurological diseases

The intricate functions of cellular processes have mystified scientists for decades. But with the help of tools like cryogenic electron microscopy (Cryo-EM), researchers at Penn State College of Medicine are starting to see ...

Cells optimized to improve 'healthy ageing' compound

The population on Earth is increasingly growing and people are expected to live longer in the future. Thus, better and more reliable therapies to treat human diseases such as Alzheimer's and cardiovascular diseases are crucial. ...

Biochemist discovers a promising enzyme to fight cancer cells

A RUDN University biochemist has studied the stimulating effect of chemical substances on the catabolic enzyme PAO (polyamine oxidase). The results could contribute to the development of drugs against cancer. The article ...

The deadly toxin acrolein has a useful biological role

Scientists from RIKEN in Japan have discovered that acrolein—a toxic substance produced in cells during times of oxidative stress—in fact may play a role in preventing the process of fibrillation, an abnormal clumping ...

Pregnancy changes perception of odours and tastes

The perception and reactions to odours and tastes can change in pregnancy, sometimes dramatically. This is also true for flies. The mechanisms, however, that trigger these changes are not understood in either mammals or insects. ...

Polyamine receptors boost food selection and reproductive success

The amount and composition of nutrients required by the body vary according to its state and physiological circumstances. Polyamines, for example, are needed in greater quantities whenever tissues develop, grow or regenerate. ...

Lessons from herbicide tolerance

(Phys.org)—Polyamines are widespread and important organic compounds involved in multiple cellular processes in living organisms. Their levels are highly regulated through a combination of processes including synthesis, ...
