Bone-lining osteolineage cells were previously implicated as contributors to hematological disorders and malignancies. A recent report in Nature now demonstrates that a specific mutation in mouse collagen-expressing osteoblastic cells leads to MDS and AML with 100% penetrance and is associated with strikingly similar findings in human patients.
The high variability and the limited knowledge of the structure of the hepatitis C virus (HCV) envelope glycoproteins (GP) are challenging hurdles for vaccine design. Recently, Kong et al. published a new model of HCV E2 GP structure in Science, revealing a globular structure, starkly contrasting from the extended model of class II fusion proteins from other Flaviviridae viruses.
Mitochondrial genes including Mfn2 are at the center of many diseases, underscoring their potential as a therapeutical target. The Chen group now identified 15-oxospiramilactone as a chemical inhibitor of the mammalian deubiquitylase USP30, acting on Mfn1 and Mfn2.
