Researchers shed new light on molecular pump that ejects anticancer agents

Sometimes cells resist medication by spitting it back out. Cancer cells, in particular, have a reputation for defiantly expelling the chemotherapy drugs meant to kill them. Researchers at The Rockefeller University have shed new light on a molecular pump that makes this possible, by determining its three-dimensional structure, down to the level of atoms.

Scientists unravel mechanism of rare, early phenomenon that can affect human development

The genetic material of an organism encodes the instructions that guide its development. These codes are not written in stone; they can change or mutate any time during the life of the organism.

MGH researchers discover regulators of gene expression programs in medulloblastoma

Massachusetts General Hospital researchers have identified a mechanism that controls the expression of genes regulating the growth of the most aggressive form of medulloblastoma, the most common pediatric brain tumor. In their report published online in Cancer Discovery, the team also identifies potential targets for future treatments.

Adolescent female offspring could be rescued from negative effects of poor maternal diet during pregnancy

Here’s some good news if you are female: Research published online in The FASEB Journal, shows that in mice, what is eaten during adolescence or childhood development may alter long-term behavior and learning, and can even “rescue” females from the negative effects on behavior resulting from a poor maternal diet during pregnancy.

Pitt study sheds light on shared roots of schizophrenia and rheumatoid arthritis

An in-depth computational analysis of genetic variants implicated in both schizophrenia and rheumatoid arthritis by researchers at the University of Pittsburgh points to eight genes that may explain why susceptibility to one of the disorders could place individuals at lower risk for the other, according to the results of a study published today in the journal npj Schizophrenia.

BUSM researchers uncover unique patterns of protein synthesis linked to increased longevity

Aging is a complex process that involves multiple metabolic and regulatory pathways. Previous studies have identified hundreds of genes whose deletion can significantly increase lifespan in model organisms. Yet, how these different aging genes and pathways are interconnected remains poorly understood.
