The process of aging is a complex phenomenon that involves progressive decline in physiological functions required for survival and fertility. To better understand the mechanisms underlying this process, scientific community has utilized several tools. Among them, mitochondrial DNA emerged as crucial factor biological aging, given dysfunction thought to significantly contribute phenomenon. Addi...

The histone acetyltransferase Gcn5 is conserved throughout eukaryotes where it functions as part of large multi-subunit transcriptional coactivator complexes that stimulate gene expression. Here, we describe how studies in the model insect Drosophila melanogaster have provided insight into essential roles played by development multicellular organisms. We outline composition and activity four di...

The flavoprotein CRYPTOCHROME (CRY) is now generally believed to be a magnetosensor, providing geomagnetic information via quantum effect on light-initiated radical pair reaction. Whilst there considerable physical and behavioural data support this view, the precise molecular basis of animal magnetosensitivity remains frustratingly unknown. A key reason for difficulty in combining biological ex...

The aim of this study is to evaluate the neuroprotective role farnesol against rotenone induced neurotoxicity in Drosophila melanogaster by survival rate study, negative geotaxis assay and estimation vivo antioxidant parameters. To induce flies, 500µmol was used. After successful induction flies were treated with 300 µmol 600 for duration experimental period. carried out estimate effect on long...

The relationship between animal mating system variation and patterns of protein polymorphism and divergence is poorly understood. Drosophila provides an excellent system for addressing this issue, as there is abundant interspecific mating system variation. For example, compared to D. melanogaster subgroup species, repleta group species have higher remating rates, delayed sexual maturity, and se...

In Drosophila, the insulin-signaling pathway controls some life history traits, such as fertility and lifespan, and it is considered to be the main metabolic pathway involved in establishing adult body size. Several observations concerning variation in body size in the Drosophila genus are suggestive of its adaptive character. Genes encoding proteins in this pathway are, therefore, good candida...

Drosophila melanogaster telomeres are composed of two retrotransposons, HeT-A and TART. Drosophila virilis has recently been shown to have telomere-specific TART elements with many of the characteristics of their D. melanogaster homologues. We now report identification of the second telomere-specific retrotransposon, HeT-A, from D. virilis. These results show that HeT-A and TART have been maint...

We used Drosophila melanogaster macrophage-like Schneider 2 (S2) cells as a model to study cell-mediated innate immunity against infection by the opportunistic fungal pathogen Candida albicans. Transcriptional profiling of S2 cells coincubated with C. albicans cells revealed up-regulation of several genes. One of the most highly up-regulated genes during this interaction is the D. melanogaster ...
