abstract = {The Epstein-Barr virus (EBV) transforms resting B cells and
is involved in the development of B cell lymphomas. We
report here that the viral noncoding RNA EBER2 accelerates B
cell growth by potentiating expression of the UCHL1
deubiquitinase that itself increased expression of the
Aurora kinases and of cyclin B1. Importantly, this effect
was also visible in Burkitt's lymphoma cells that express
none of the virus's known oncogenes. Mechanistically, EBER2
bound the UCHL1 messenger RNA (mRNA), thereby bringing a
protein complex that includes PU.1, a UCHL1 transactivator,
to the vicinity of its promoter. Although the EBV oncogene
LMP1 has been suggested to induce UCHL1, we show here that
EBER2 plays a much more important role to reach significant
levels of the deubiquitinase in infected cells. However,
some viruses that carried a polymorphic LMP1 had an
increased ability to achieve full UCHL1 expression. This
work identifies a direct cellular target of a viral
noncoding RNA that is likely to be central to EBV's
oncogenic properties.},
