A group of collaborative researchers, led by Alan Warren’s group at the LMB, have discovered a surprising link between human ribosome maturation and cancer.
The team identified the conserved mechanism that underlies a critical step in the maturation of ribosomes and showed that this step is defective in an inherited form of bone marrow failure that is associated with significant leukemia predisposition (Shwachman-Diamond syndrome, SDS).
Link Between Ribosome Maturation and Cancer
LMB scientists reconstruct ‘Nature’s first enzyme’.
The origin of life is one of the great, unsolved mysteries of biology. In a quest to improve understanding of how life might have originally emerged, a group of LMB scientists have managed to construct an enzyme that can mimic how the first forms of life may have arisen and begun to evolve – before DNA came along.
Hijacking protein quality control to regulate cellular communication.
A small molecule to correct protein folding defects.
The deposition of misfolded proteins is a central characteristic of many devastating diseases including neurodegenerative diseases such as Alzheimer’s, Parkinson’s, Huntington’s, amyotrophic lateral sclerosis and prion diseases. In principle, improving the cells’ ability to deal with misfolded proteins should reduce the pathology in these diverse neurodegenerative diseases.
First X-ray crystal structure of dynein motor domain
The first X-ray crystal structure of the motor domain of cytoplasmic dynein, a protein that uses the cellular energy from ATP to walk along microtubule tracks that run throughout the cell, has been solved.
Cytoplasmic dynein moves numerous cargos around the cell including proteins and RNAs that set up the cell polarity, membraneous organelles, aggregated proteins that are toxic unless collected and disposed of, and even whole nuclei.
Propagation of mutant SOD1 misfolding.
Amyotrophic lateral sclerosis (ALS) is caused by the progressive dysfunction of specific nerve cells that control muscle movement. It belongs to a group of devastating neurodegenerative diseases including Alzheimer’s, Parkinson’s, Huntington’s and prion diseases. Each disease is caused by the progressive accumulation of specific proteins in an aberrant, misfolded shape. The formation of the protein deposits is somehow toxic to nerve cells but why and how they initially form is unclear.
