Measurement of Poly A Tail Length from Drosophila Larva Brain and Cell Line.

ABSTRACT: Polyadenylation is a crucial posttranscriptional modification that adds poly(A) tails to the 3' end of mRNA molecules. The length of the poly(A) tail is tightly regulated by cellular processes. Dysregulation of mRNA polyadenylation has been associated with abnormal gene expression and various diseases, including cancer, neurological disorders, and developmental abnormalities. Therefore, comprehending the dynamics of polyadenylation is vital for unraveling the complexities of mRNA processing and posttranscriptional gene regulation. This paper presents a method for measuring poly(A) tail lengths in RNA samples isolated from Drosophila larval brains and Drosophila Schneider S2 cells. We employed the guanosine/inosine (G/I) tailing approach, which involves the enzymatic addition of G/I residue
