Purines are nitrogenous bases that constitute fundamental building blocks of DNA and RNA. Through two primary routes—de novo synthesis and salvage pathways—cells maintain purine pools required for ...

This image illustrates the chemical structure of a purine molecule, highlighting the numbering of the carbon and nitrogen atoms. The purine structure consists of a pyrimidine ring (positions 1 to 6) ...

Cell metabolism is often thought of as the process of breaking down sugars to create energy, but the process also involves all the biosynthetic reactions necessary to sustain life. One of these ...

Northwestern Medicine scientists have uncovered a surprising link between a tiny cellular engine and the way cancer cells build the DNA they need to proliferate, according to a new study published in ...

Purine nucleotides are essential for cell growth and function as they serve as nucleic acid building blocks, signaling molecules, and energy carriers. Treatments that inhibit their synthesis offer a ...

Parkinson's disease (PD), the second most common neurodegenerative disorder globally, has long baffled scientists with its progressive nature and debilitating effects on motor function. A recent study ...

While modern life includes many conveniences, humans are still incessantly exposed to a variety of metabolic stresses we have never experienced before. Our immune systems are constantly trying to ...

NUDT5 enzyme acts as a molecular scaffold that maintains metabolic balance. Inside every cell, a finely tuned metabolic network determines when to build, recycle or stop producing essential molecules.

Scientists from Duke-NUS Medical School and their international collaborators have developed a new computational tool that maps how gene pathways interact in complex biological systems. Using this ...
