... eggshell. In C. elegans oocytes and embryos, SEIP-1 is associated with LDs and is crucial for controlling LD size and lipid homeostasis. The seip-1 deletion mutants reduced the ratio of polyunsaturated fatty acids (PUFAs) in their embryonic fatty acid pool. Interestingly, dietary supplementation...

...Matthew G. Niepielko; Nir Yakoby Drosophila eggshells display remarkable morphological diversity among species; however, the molecular origin of this structural diversification is mostly unknown. Here, we analyzed the dorsal ridge (DR), a lumen-like structure along the dorsal side of eggshells...

...Yukio Nakamura; Tatsuo Kagesawa; Minori Nishikawa; Yoshiki Hayashi; Satoru Kobayashi; Teruyuki Niimi; Kenji Matsuno Patterning of the respiratory dorsal appendages (DAs) on the Drosophila melanogaster eggshell is tightly regulated by epidermal growth factor receptor (EGFR) signaling. Variation...

... Slmb Oogenesis Egg chamber Eggshell Destruction of intracellular proteins at the 26S proteasome is a finely regulated process that determines the half-life of most key cell regulators( Hershko and Ciechanover,1998 ). The proteasome is a 25 MDa multi-subunit protease complex that recognizes...

...David H. Tran; Celeste A. Berg bullwinkle ( bwk ) regulates embryonic anteroposterior patterning and, through a novel germline-to-soma signal, morphogenesis of the eggshell dorsal appendages. We screened for dominant modifiers of the bullwinkle mooseantler eggshell phenotype and identified shark...

...Wu-Min Deng; Mary Bownes ABSTRACT The Drosophila eggshell, which has a pair of chorionic appendages (dorsal appendages) located asymmetrically along both the anterior/posterior and dorsal/ventral axes, provides a good model to study signal instructed morphogenesis. We show that the Broad-Complex...
