Eyes absent in the cockroach panoistic ovaries regulates proliferation and differentiation through ecdysone signalling.
Ramos S, Chelemen F, Pagone V, Elshaer N, Irles P, Piulachs MD. Ramos S, et al. Insect Biochem Mol Biol. 2020 Aug;123:103407. doi: 10.1016/j.ibmb.2020.103407. Epub 2020 May 15. Insect Biochem Mol Biol. 2020. PMID: 32417417
Eya is also involved in insect oogenesis, although studies in this sense are limited to D. melanogaster, which has meroistic ovaries, and where eya mutations abolish gonad formation. In the present work we studied the function of eya in the panoistic ovary of …

BACKGROUND INFORMATION: In insects, the action of microRNAs (miRNAs) on oogenesis has been explored only in dipterans, which possess meroistic ovaries, a highly modified ovarian type. Here we study miRNA function in the most primitive, panoistic type of ovaries …
