CycA is involved in the control of endoreplication dynamics in the Drosophila bristle lineage.
We focused on CycA, which has been described to function exclusively during mitosis in Drosophila. Using developing mechanosensory organs as model system and PCNA::GFP to follow endocycle dynamics, we show that (1) CycA proteins accumulate during the last period of endoreplication, (2) both CycA los...
Definitive erythropoiesis in the trunk of zebrafish embryos.
[Inheritance of longitudinal shell bands in the snails Littorina obtusata and Littorina saxatilis (Gastropoda, Prosobranchia)].
The hypothesis of a monogenic inheritance of dark longitudinal bands on the shell in the gastropods Littorina obtusata and L. saxatilis was checked. One gene having two alleles proved to be responsible for the shell banding pattern in both of the species. The presence of bands was a...
Evolutionary biology: the origins of novelty.
Effects of human contraceptive on reproduction and offspring in Chrysomya megacephala.
We found the degenerated nuclei and/or incomplete mitochondrial derivative, axoneme and vacuolated flagella. Regarding deformity in F1, F2 and F3 ovariole, ultrastructural alteration observed by scanning electron microscopy (SEM) included malformations involving fragile enveloping peritoneal sheath,...
GABA inhibition of luminescence from lantern shark (Etmopterus spinax) photophores
We also demonstrated that BICU can induce light per se by provoking pigment retraction in the pigmented cells composing the iris-like structure of the photophore, attaining, however, only about 10% of hormonally induced luminescence intensity at 10(-3)mol L(-1). This strongly supports that a GABA in...
Antibody-based targeting of interferon-alpha to the tumor neovasculature: a critical evaluation.
We describe the design, production and characterization of a novel immunocytokine, in which murine interferon-alpha2 was sequentially fused with the tumor-targeting antibody fragment scFv(F8), specific to the alternatively-spliced EDA domain of fibronectin. The resulting fusion protein (F8-IFNa) cou...
IKKepsilon: a kinase at the intersection of signaling and membrane traffic.
The ability to coordinate membrane trafficking events in space and time is of fundamental importance in biology. Polarized trafficking is essential for processes as diverse as cytokinesis, regulated endocytosis, cell motility, and morphogenesis, yet the interface between cellular sig...
DREF is critical for Drosophila bristle development by regulating endoreplication in shaft cells.
We focused our attention on macrochaetes bristle development system. Utilizing cell lineage analysis focusing on a single posterior scutellar (PSC) macrochaete sensory organ precursor (SOP) lineages in combination with GAL4/UAS targeted expression system for DREF double strand RNA, we revealed that...
Characterization and tissue-specific expression patterns of the Plasmodium chabaudi cir multigene family.
Variant antigens expressed on the surface of parasitized red blood cells (pRBCs) are important virulence factors of malaria parasites. Whereas Plasmodium falciparum erythrocyte membrane proteins 1 (PfEMP1) are responsible for sequestration of mature parasites, little is known about p...
