Cells may need some reactive forms of oxygen to maintain health

Within our bodies, high levels of reactive forms of oxygen can damage proteins and contribute to diabetic complications and many other diseases. [More]
New research article reveals global patterns of genetic variation

New research article reveals global patterns of genetic variation

Published in today's edition of Nature, the research led by Dr Monkol Lek of the University of Sydney and Dr Daniel MacArthur of The Broad Institute of MIT and Harvard Universities reveals patterns of genetic variation worldwide by sequencing the exomes of 60,706 individuals with diverse geographic ancestries, including European, African, South Asian, East Asian and Latino populations.

Pancreatic cancer cells find alternative source of nutrition to avoid starvation

Pancreatic cancer cells find alternative source of nutrition to avoid starvation

Pancreatic cancer cells avert starvation in dense tumors by ordering nearby support cells to supply them with an alternative source of nutrition. [More]
Research findings could provide framework for understanding fertilization mechanism

Research findings could provide framework for understanding fertilization mechanism

A Japanese research group has determined the crystal structure of the JUNO protein, an egg surface protein essential for fertilization. These structure-based mutational analyses elucidated a mechanism of the interaction between egg (JUNO protein) and sperm (IZUMO1) on a molecular level. [More]

Study uses computer-based approaches to characterize Zika virus genome

The sudden emergence of the Zika virus epidemic in Latin America in 2015-16 has caught the scientific world unawares. [More]
Brazilian study discovers promising therapeutic and diagnostic target for treatment of melanoma

Brazilian study discovers promising therapeutic and diagnostic target for treatment of melanoma

A Brazilian study shows that inhibition of an RNA named RMEL3, which is encoded by a previously uncharacterized gene (also named RMEL3), can reduce the viability of cultured melanoma cells by up to 95%. [More]
Iron-containing catalysts can alter amino acids to help develop new drug candidates

Iron-containing catalysts can alter amino acids to help develop new drug candidates

For medicinal chemists, making tweaks to peptide structures is key to developing new drug candidates. Now, researchers have demonstrated that two iron-containing small-molecule catalysts can help turn certain types of amino acids -- the building blocks of peptides and proteins -- into an array of potential new forms, even when part of a larger peptide, while preserving a crucial aspect of their chemistry: chirality, or "handedness."

Researchers discover pathway linking oxidative stress and cysteine in Huntington's disease

Researchers at Johns Hopkins Medicine report they have identified a biochemical pathway linking oxidative stress and the amino acid cysteine in Huntington's disease. [More]
Scientists design and construct 10 large protein icosahedra to improve drug delivery

Scientists design and construct 10 large protein icosahedra to improve drug delivery

Using novel computational and biochemical approaches, scientists have accurately designed and built from scratch 10 large protein icosahedra--polyhedra with 20 faces--similar to viral capsids that carry viral DNA. [More]
Researchers identify unique mechanism to suppress colorectal cancer tumors in mice

Researchers identify unique mechanism to suppress colorectal cancer tumors in mice

A new scientific study has identified why colorectal cancer cells depend on a specific nutrient, and a way to starve them of it. Over one million men and women are living with colorectal cancer in the United States. [More]
Researchers discover how Zika virus travels from pregnant mother to fetus

Researchers discover how Zika virus travels from pregnant mother to fetus

Zika virus can infect numerous cell types in the human placenta and amniotic sac, according to researchers at UC San Francisco and UC Berkeley who show in a new paper how the virus travels from a pregnant woman to her fetus. They also identify a drug that may be able to block it. [More]
Scientists capture atomic level snapshots of how key enzyme modifies signaling proteins

Scientists capture atomic level snapshots of how key enzyme modifies signaling proteins

Scientists have captured atomic level snapshots showing how one key enzyme modifies a protein involved in turning genes on or off inside cells. Understanding this process-which is particularly important when cells are first taking on specialized identities such as nerve cells, muscle, skin, and so on-helps explain how complex organisms can arise from a finite number of genes.

Biochemists design genetic poison pill to thwart coxsackievirus B3

It has a funny name - coxsackievirus - but there's nothing funny about how this tiny germ and its close relatives sicken their hosts. [More]
