Abstract
The phenotypic manifestations of increased expression of the Bap170 and e(y)3 (SAYP) genes in D. melanogaster were analyzed. Using the wing disc model, we show that moderate co-expression of Bap170 and e(y)3 genes in wing discs leads to abnormalities in wing veining. which was probably caused by suppression of EGFR/Ras/MAPK signaling pathways. Strong induction of co-expression of the above genes in wing discs leads to complete suppression of wing development in adults. Ubiquitous co-expression of Bap170 and e(y)3 is lethal at the 1st instar larval stage and leads to the formation of melanotic tumors. The above phenotypes are observed exclusively when Bap170 and e(y)3 are co-expressed. This evidence suggests a robust synergistic effect of the combined action of these genes, which is manifested in the hyperactivity of cell proliferation and differentiation.
期刊介绍:
Doklady Biochemistry and Biophysics is a journal consisting of English translations of articles published in Russian in biochemistry and biophysics sections of the Russian-language journal Doklady Akademii Nauk. The journal''s goal is to publish the most significant new research in biochemistry and biophysics carried out in Russia today or in collaboration with Russian authors. The journal accepts only articles in the Russian language that are submitted or recommended by acting Russian or foreign members of the Russian Academy of Sciences. The journal does not accept direct submissions in English.
