Optogenetic perturbation of lipid droplet localization affects lipid metabolism and development in Drosophila

Journal of Lipid Research
Lipid droplets (LDs) are dynamic organelles crucial for lipid storage and homeostasis. Despite extensive documentation of their importance, the causal relationship between LD localization and function in health and disease remains inadequately understood.

Oogenesis in Caenorhabditis elegans

, 2001
Oogenesis is the process of forming the female gamete, i.e., the ovum or egg. In Caenorhabditis elegans, gametes derive from a tissue called the germ line, which is specified early in embryonic development.

Oogenesis: Setting one sister above the rest

, 2001
Recent studies have revealed that the Par-1 protein, in addition to its established role in anterior–posterior patterning of the Drosophila oocyte, has both microtubule-dependent and microtubule-independent roles very early in ...

Изменение актинового цитоскелета и кольцевых каналов питающих клеток Calliphora erythrocephala в оогенезе

Фактори експериментальної еволюції організмів, 2014
Aims. The purpose of this study was to investigate changes of the actin cytoskeleton syncytial clusters in ovaries C. erythrocephala at different stages of oogenesis. Methods. Ovarioles were stained phalloidin- FITC and DAPI.

Decoding zebrafish oogenesis: From primordial germ cell development to fertilization

Oogenesis – the formation and development of an oocyte – is fundamental to reproduction and embryonic development. Due to its accessibility to genetic manipulations and the ability to culture and experimentally manipulate oocytes ex vivo, zebrafish has ...

The Memory Gene, Murashka, Is a Regulator of Notch Signalling and Controls the Size of the Drosophila Germline Stem Cell Niche

Biomolecules
We identified Murashka, a RING finger protein, in an oogenesis screen as a regulator of Drosophila ovary germline stem cell niche development. Mutant alleles of murashka exhibited an enlarged niche phenotype reminiscent of increased Notch signalling and ...

Characterization of the Drosophila Egfl7/8 ortholog during oogenesis

, 2006
During animal development precise coordination and regulation of cell proliferation, differentiation and cell death is required for proper tissue organization. This is achieved through specific cell communication by intercellular signals. Cell death, for

Polystyrene micro- and nanoparticles induce ultrastructural alterations and disrupt gametogenesis and midgut homeostasis in the soil oligochaete Enchytraeus albidus

The European Zoological Journal
Plastic pollution in terrestrial ecosystems is an increasing concern, yet its impact on soil fauna, particularly minute annelids, remains understudied.
