Molecular regulation underlying emergency hematopoiesis uncovered

If the body’s emergency hematopoiesis program activates, it signifies an alert state of the immune system and serves two functions: In comparison to “normal mode” hematopoiesis, the emergency program results in enhanced replacement of immune cells consumed during infections or inflammations.

Research shows how bacteria silence potentially deadly genes

Humans are all made of collections of cells, where each cell contains instructions in the DNA to become another cell.

7 Jan 2022

Experts identify proteins that regulate dual processes

According to recent research, the protein UBR7 acts as a histone chaperone and controls histone re-deposition at certain sites at the time of DNA replication.

Researchers identify a new approach to triggering differentiation in acute myeloid leukemia

In the late 1980s, scientists developed a revolutionary approach to treating acute myeloid leukemia (AML), a type of blood cancer. Called differentiation therapy, it amounted to a bona fide cure for many patients.
