Within the short span of the cell cycle, Poly(ADP-ribose) (pADPr) can be rapidly produced by Poly(ADP-ribose) Polymerases (PARPs) and degraded by Poly(ADP-ribose) Glycohydrolases (PARGs). Here we show that changes in association between pADPr and heterogeneous nuclear ribonucleoproteins (hnRNPs) regulate germline stem cell maintenance and egg chamber polarity during oogenesis in Drosophila. The association of pADPr and Hrp38, an ortholog of human hnRNPA1, disrupts the interaction of Hrp38 with the 5′UTR of DE-cadherin mRNA, thereby diminishing DE-cadherin translation in progenitor cells. Following the reduction of DE-cadherin level, germline stem cells leave the stem cell niche and differentiate. Defects in either pADPr catabolism or Hrp38 function cause a decreased translation of DE-cadherin, leading to a loss of germline stem cells and mislocalization of oocytes in the ovary. Taken together, our findings suggest that Hrp38 and its association with pADPr control germline stem cell self-renewal and oocyte localization by regulating DE-cadherin translation.
