Conclusions In this study, we present data which indicate that knockdown of could induce mitochondrial stress and result in cell death via apoptotic and autophagy pathways. storage droplet 2 (Lsd2) [9]. More importantly, and higher animals share the same basic metabolic functions and lipid metabolism-related genes [11,12]. The function of in lipid metabolism in is well known. For example, analyses with GFP (green fluorescent protein)-tagged displayed its presence on the surface of LDs in fat body cells [13]. In addition, loss of function or overexpression of in indicated that probably facilitates lipid mobilization [8]. studies identified as a PKA phosphorylation target [14], while mutant analysis demonstrated an essential role of as a pro-lipolytic effector of the AKH/AKHR pathway on the LD surface [2]. To date, other functions and genetic regulatory mechanisms of this gene are still under investigation. In this study, the function of was further investigated in by selective knockdown of the gene using the GAL4-UAS targeted expression system in combination with RNA interference [15]. By crossing tissue and developmentally specific GAL4 driver fly lines with a fly line carrying the UAS-gene can be specifically knocked down in any desired tissue or developmental stage. The knockdown experiments in this study revealed that is necessary for the development of wings, possibly through maintaining the function of mitochondria. 2. Results 2.1. Effect of Lsd1 Knockdown in Various Tissues and Entire Drosophila We knocked down by crossing the UAS-fly line with several GAL4 driver lines. As summarized in Table 1, knockdown in the whole fly by Act5C-GAL4 or Tubp-GAL4 resulted in a lethal phenotype at the embryonic stage. knockdown by En-Gal4 also caused lethality, probably because of the reported leaky expression of GAL4 during embryogenesis [16,17]. These results indicate an essential role of the gene for viability and/or development of knockdown in the fat body caused a delay in growth at 25 C and lethality at 28 C. These results are consistent with previous studies of mutants and indicate that plays an important role in lipid metabolism [8]. The specific knockdown of the gene in wing discs with MS1096-GAL4 driver resulted in a severe atrophied wing phenotype, suggesting that plays unexplored role/s during wing development. Eye disc-specific knockdown of the gene by GMR-GAL4 (at 28 C) exhibited no detectable phenotype, suggesting that plays no apparent role during eye development. These observations suggest the tissue-specific role of in the development, although the possibility of low level expression of GAL4 protein leading to insufficient knockdown of in eye disc can not be excluded. Table 1 Summary of phenotypes induced by knockdown of with various GAL4 driver lines. in lipid metabolism is well known, its potential function in wing development has not been explored. We therefore focused on the analyses of the wing phenotype induced by knockdown.

For example, analyses with GFP (green fluorescent protein)-tagged displayed its presence on the surface of LDs in fat body cells [13]. In addition, loss of function or overexpression of in indicated that probably facilitates lipid mobilization [8]. studies identified as a PKA phosphorylation target [14], while mutant analysis demonstrated an essential role of like a pro-lipolytic effector of the AKH/AKHR pathway within the LD surface [2]. To day, other functions and genetic regulatory mechanisms of this gene are still under investigation. With this study, the function of was further investigated in by selective knockdown of the gene using the GAL4-UAS targeted manifestation system in combination with RNA interference [15].
