Minocycline protects the immature white matter against hyperoxia.

Poor neurological outcome in preterm infants is associated with periventricular white matter damage and hypomyelination, often caused by perinatal inflammation, hypoxia-ischemia, and hyperoxia. Minocycline has been demonstrated in animal models to protect the immature brain against inflammation and hypoxia-ischemia by microglial inhibition. Here we studied the effect of minocycline on white matter damage caused by hyperoxia.

Mild Nijmegen breakage syndrome phenotype due to alternative splicing.

Hypomorphic mutations of the NBS1 gene are responsible for Nijmegen breakage syndrome (NBS), characterized by microcephaly, chromosomal instability, radiosensitivity, immunodeficiency and high cancer predisposition. Over 90% of NBS patients are homozygous for the 657Delta5 mutation and are of Slavic origin; however, 10 further truncating mutations have been identified in patients of other ethnic origin. Partially functional proteins produced by alternative initiation of translation, and possibly diminishing the severity of the NBS phenotype, have been described for several NBS1 mutations.
