Steroid Control of Longevity in Drosophila melanogaster [PDF]

open access: yes, 2003
Ecdysone, the major steroid hormone of Drosophila melanogaster, is known for its role in development and reproduction. Flies that are heterozygous for mutations of the ecdysone receptor exhibit increases in life-span and resistance to various stresses ...

The role of cytochrome c in caspase activation in Drosophila melanogaster cells [PDF]

open access: yes, 2002
The release of cytochrome c from mitochondria is necessary for the formation of the Apaf-1 apoptosome and subsequent activation of caspase-9 in mammalian cells.

Ecdysteroids: A novel class of anabolic agents? [PDF]

open access: yes, 2015
Increasing numbers of dietary supplements with ecdysteroids are marketed as “natural anabolic agents”. Results of recent studies suggested that their anabolic effect is mediated by estrogen receptor (ER) binding. Within this study the anabolic potency of

Bab2 Functions as an Ecdysone-Responsive Transcriptional Repressor during Drosophila Development

open access: yesCell Reports, 2020
Summary: Drosophila development is governed by distinct ecdysone steroid pulses that initiate spatially and temporally defined gene expression programs. The translation of these signals into tissue-specific responses is crucial for metamorphosis, but the

Mechanisms regulating nutrition-dependent developmental plasticity through organ-specific effects in insects [PDF]

open access: yes, 2013
Nutrition, via the insulin/insulin-like growth factor (IIS)/Target of Rapamycin (TOR) signaling pathway, can provide a strong molding force for determining animal size and shape.

Increased insulin/insulin growth factor signaling advances the onset of metamorphosis in Drosophila. [PDF]

open access: yesPLoS ONE, 2009
Mechanisms by which attainment of specific body sizes trigger developmental transitions to adulthood (e.g. puberty or metamorphosis) are incompletely understood.

Juvenile hormone regulates body size and perturbs insulin signaling in Drosophila [PDF]

open access: yes, 2014
The role of juvenile hormone (JH) in regulating the timing and nature of insect molts is well-established. Increasing evidence suggests that JH is also involved in regulating final insect size.

Effects of contaminants of emerging concern on Megaselia scalaris (Lowe, Diptera: Phoridae) and its microbial community. [PDF]

open access: yes, 2017
Drought, rising temperatures, and expanding human populations are increasing water demands. Many countries are extending potable water supplies by irrigating crops with wastewater.

The steroid-hormone ecdysone coordinates parallel pupariation neuromotor and morphogenetic subprograms via epidermis-to-neuron Dilp8-Lgr3 signal induction

open access: yesNature Communications, 2021
Pupariation in Drosophila is triggered by the steroid-hormone ecdysone and requires coordination between associated behavioral and body-reshaping motor subprograms.

Autophagy occurs upstream or parallel to the apoptosome during histolytic cell death [PDF]

open access: yes, 2006
Histolysis refers to a widespread disintegration of tissues that is morphologically distinct from apoptosis and often associated with the stimulation of autophagy. Here, we establish that a component of the apoptosome, and pivotal regulator of apoptosis,
