The diminutive dMyc a homolog of the human MYC gene is responsible for cell- apoptosis and its upregulation is responsible for determining the fate of cancerous growth in humans and Drosophila model. This work implores the requirement of dMyc and its expression as one of the major regulator of cancer with other proteins and repression of dMyc mRNA in Drosophila S2 cells. Here we report protein complex of Argonaute 1 AGO1 Bag of marbles Bam and Brain tumor Brat proteins and not the individual factor of this complex repression of dMyc mRNA in Drosophila Schneider 2 cells and promote differentiation in cystoblast of Drosophila ovary. These results exhibit the significant role of this complex including master differentiation factor Bam with other various differentiation factor Brat and microRNA pathway component AGO1 which may negatively regulate dMyc mRNA and so the dMyc protein.
