.... Drosophila Fat2 is a cadherin related to Fat; however, its role during planar cell polarity has not been studied. Here, we have generated mutations in fat2 and show that Fat2 is required for the planar polarity of actin filament orientation at the basal side of ovarian follicle cells. Defects in actin...

...Salim Abdelilah-Seyfried; Daniel N. Cox; Yuh Nung Jan Drosophila Bazooka and atypical protein kinase C are essential for epithelial polarity and adhesion. We show here that wild-type bazooka function is required during cell invasion of epithelial follicle cells mutant for the tumor suppressor discs...

... patterns the somatic follicular epithelium, establishing the dorsoventral asymmetry of eggshell and embryo. Analysis of follicle cell clones homozygous for a null allele of Ras demonstrates that Ras is required cell-autonomously to repress pipe transcription, the critical first step in embryonic...

...Jonaki Sen; Jason S. Goltz; Mary Konsolaki; Trudi Schüpbach; David Stein ABSTRACT Drosophila embryonic dorsal-ventral polarity originates in the ovarian follicle through the restriction of pipe gene expression to a ventral subpopulation of follicle cells. Pipe, a homolog of vertebrate...

... a temperature-sensitive mutation or exogenous ecdysone results in corresponding changes in early gene expression. The stage 10 follicle cell expression of E75 in wild-type, K10 and EGF receptor (Egfr) mutant egg chambers reveals regulation of E75 by both the Egfr and ecdysone signaling pathways. Genetic...

...Muriel Grammont,; Bernard Dastugue; Jean-Louis Couderc ABSTRACT We have characterized a new gene, called toucan , that is expressed and required in germline cells to promote proper differentiation of the somatic follicle cells. toucan mutant ovaries are defective in (i) the enclosure of newly...

... that Bic-D is indeed required in the later stages of oogenesis. In ovaries from mutant females, oocyte growth is reduced, apparently due to defects in nurse-cell-to-oocyte transport. Smaller oocyte size results in the misalignment of follicle cells and the underlying germ line, leading to ventralization...

.... In the present study, we have examined the role of Ras in the migration of a small subset of follicle cells, known as the border cells, during Drosophila oogenesis. A dominant-negative Ras protein inhibited cell migration when expressed specifically in border cells during the period when these cells normally...
