Hi Dorothy,
The Mouse 430A 2.0, Mouse 430 2.0, and MOE430A are different arrays.
As I understand it, the hgu133plus2 and hgu133plus2.db packages contained
the same information, only in different formats. But only the
hgu133plus2.db format appears to be included in the current release
(2.3) of Bioconductor.
If you are asking whether there have been any changes in the annotations
for the current release (2.3) compared to earlier releases, the
annotations are always changing, ad you can expect differences of the
order of maybe 5-10%, sometimes more, from one release to the next. That
is because the underlying databases that are the sources of the
annotations - EntrezGene, UniGene and RefSeq, for example - are constantly
changing.
Hope this answers your question.
Regards,
Maria
