Term Name:	positive regulation of nuclear-transcribed mRNA poly(A) tail shortening
Synonyms:	positive regulation of 3' to 5' mRNA deadenylation, positive regulation of mRNA deadenylation, positive regulation of nuclear mRNA poly(A) tail shortening
Definition:	Any process that increases the frequency, rate or extent of poly(A) tail shortening of a nuclear-transcribed mRNA. Poly(A) tail shortening is the decrease in length of the poly(A) tail of an mRNA from full length to an oligo(A) length.
