Brazilian scientists unveil chemotherapy resistance mechanism related to p53 mutation

Instituto Nacional de Ciência e Tecnologia de Biologia Estrutural e Bioimagem (INBEB)
Peer-Reviewed Publication

Brazilian study uncovered an anticancer chemotherapy resistance mechanism related to amyloid aggregation of mutant p53. The research was conducted in cells derived from glioblastoma, a super aggressive brain tumor, and in living cells. The results open up new opportunities for the development of more effective therapies against cancer.

Jaguars could prevent a not-so-great American biotic exchange

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

In eastern Panama, canid species from North and South America are occurring together for the first time. Urban and agricultural development and deforestation along the Mesoamerican Biological Corridor might be generating a new passageway for these invasive species adapted to human disturbance.

The sympathetic nervous system can inhibit the defense cells in autoimmune disease

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

Using an experimental model of multiple sclerosis, the scientists found that the sympathetic nervous system can limit the generation of effector responses by inhibiting the action of the cells that attack an antigen taken as a threat by the immune system.

The wild relatives of major vegetables, needed for climate resilience, are in danger

The Alliance of Bioversity International and the International Center for Tropical Agriculture
Peer-Reviewed Publication

The genes that make crop wild relatives robust have the potential to make their cultivated cousins -- our food plants -- better prepared for a harsh climate future. But a series of new research papers show these critical plants are imperiled.
