Large-scale sequence analysis of avian influenza isolates.

The spread of H5N1 avian influenza viruses (AIVs) from China to Europe has raised global concern about their potential to infect humans and cause a pandemic. In spite of their substantial threat to human health, remarkably little AIV whole-genome information is available. We report here a preliminary analysis of the first large-scale sequencing of AIVs, including 2196 AIV genes and 169 complete genomes.

Characterization of the MLL partner gene AF15q14 involved in t(11;15)(q23;q14).

Translocations interrupting the mixed lineage leukemia gene (MLL) occur in 7-10% of acute lymphoblastic leukemia (ALL) and 5-6% of acute myeloid leukemia (AML) cases. One of these translocations, t(11;15)(q23;q14), occurs rarely in both ALL and AML. The gene on chromosome 15, AF15q14, was cloned recently in a patient with AML-M4.
