Expression of Mef2Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4Mef2.PR result in one extra row of Mef2-positive cardiac cells in the embryo, whereas the tin-positive cardiac cells are not affected.
Co-expression of vgScer\UAS.T:Ivir\HA1 and Mef2Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4Mef2.PR in the embryo has a synergistic effect on cardiac cells; there are two extra rows of Mef2-positive cardiac cells and six tin-positive cardiac cells per hemisegment, with many more tin-positive pericardial cells.
Co-expression of sdScer\UAS.T:Zzzz\FLAG and Mef2Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4Mef2.PR in the embryo results in a cardiac cell phenotype similar to that of embryos expressing sdScer\UAS.T:Zzzz\FLAG alone under the control of Scer\GAL4Mef2.PR.
