# Prostaglandins limit nuclear actin rod formation during Drosophila oogenesis

## TL;DR

This study shows that prostaglandins help control nuclear actin rod formation in fruit fly egg development.

## Contribution

The study demonstrates that prostaglandin signaling limits nuclear actin rod formation in Drosophila oogenesis.

## Key findings

- Loss of prostaglandin synthesis increases the frequency of nuclear actin rods in Drosophila oogenesis.
- PG signaling affects rod length and number, suggesting a regulatory role in nuclear actin dynamics.

## Abstract

Expression of GFP-Actin results in nuclear actin rod formation during specific stages of
Drosophila melanogaster
oogenesis. Loss of prostaglandin (PG) synthesis and signaling results in an increased frequency of cells with nuclear actin rods; there are less rods per cell, but the rods are longer. These findings suggest that loss of PGs results in increased nuclear actin and are consistent with prior findings assessing the roles of PGs in modulating endogenous nuclear actin. Thus, GFP-Actin rod formation can be used as a tool to screen for new regulators of nuclear actin.
