Scientists shed light on mechanisms responsible for maturation of the splicing machinery

Alternative Splicing is an extraordinarily complex process that requires the coordinated action of multiple proteins, each specialized in very specific functions. These proteins are assembled and matured, forming a kind of consortium of proteins that perform these gene reading functions.

Researchers grow intestinal organoids to study why bats infected with viruses do not succumb to diseases

Experiments attempting to explain why bats can be infected with many viruses at a time without succumbing to diseases such as COVID-19-;knowledge that could help us to reduce the threat to humans of infectious disease-;have struggled until now with the fact that live wild bats make poor research subjects.

Study identifies novel function for existing protein

Researchers recently identified a new role of the protein tBID, which was to date linked to the regulatory role in cancer and cell death. But tBID also directly mediates apoptosis (controlled cell death).
