Ethnomedicinal Uses, Phytochemistry, Pharmacological Activities, and Toxicology of the Subfamily Gomphrenoideae (Amaranthaceae): A Comprehensive Review

Chemistry &Biodiversity, EarlyView.
ABSTRACT The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its ...

Effect of precocene II, ecdysone and juvenile Hormone on the glicogen concentration in pupae of Stomocys calcitram (Diptera muscidae)

Memorias do Instituto Oswaldo Cruz, 1988
Third instar larvae of Stomoxys calcitrans (L.) were treated with precocene II, ecdysone and juvenile hormone. The larvae were allowed to develop until pupation and when it occurred, determination of glycogen levels was assayed.

microRNA-14 as an efficient suppressor to switch off ecdysone production after ecdysis in insects

RNA Biology, 2019
The precise increase and decrease of hormone ecdysone are critical for accurate development in insects. Most previous works focus on transcriptional activation of ecdysone production; however, little is known about the mechanism of switching off ecdysone

Bridging the Gap Between Human Toxicology and Ecotoxicology Under One Health Perspective by a Cross‐Species Adverse Outcome Pathway Network for Reproductive Toxicity

Environmental Toxicology and Chemistry, EarlyView.
Cross‐species extrapolation of adverse outcome pathway network on reproductive toxicity under the One Health perspective using new approach methodologies. AOP = adverse outcome pathway. Abstract Although ecotoxicological and toxicological risk assessments are performed separately from each other, recent efforts have been made in both disciplines to ...

Long‐term impact of exposure to Royal Guard, a pyriproxyfen‐based bed net, on pyrethroid‐resistant malaria vectors from Cameroon using DNA‐based metabolic resistance markers

Pest Management Science, Volume 81, Issue 4, Page 2165-2180, April 2025.
We used recently detected P450 DNA‐based markers of pyrethroid resistance in both Anopheles funestus and Anopheles gambiae to demonstrate that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood feeding ability and interestingly ...

26-[125I]iodoponasterone A is a potent ecdysone and a sensitive radioligand for ecdysone receptors. [PDF]

Proceedings of the National Academy of Sciences, 1988
The effects of ecdysone, the steroid molting hormone of arthropods, are of considerable interest both to insect physiologists and to those studying steroid-regulated gene expression. Yet progress in understanding ecdysone receptors has been inhibited by the lack of a suitable highly radioactive hormone analog with high affinity for the receptor.

Molecular surveillance of resistance mutations in invasive populations of Spodoptera frugiperda in Europe, for evidence‐based pest control

Pest Management Science, EarlyView.
All Spodoptera frugiperda were rice strain with two haplotypes, likely from a common mixed source. ABCC2 and Ace‐1 mutations, conferring resistance to Bacillus thuringiensis and organophosphates/carbamates, respectively, were detected. Abstract BACKGROUND The invasive fall armyworm (Spodoptera frugiperda, FAW), a highly destructive pest affecting more ...

Translational control by the DEAD Box RNA helicase belle regulates ecdysone-triggered transcriptional cascades.

PLoS Genetics, 2012
Steroid hormones act, through their respective nuclear receptors, to regulate target gene expression. Despite their critical role in development, physiology, and disease, however, it is still unclear how these systemic cues are refined into tissue ...

Unexpected role of the steroid-deficiency protein ecdysoneless in pre-mRNA splicing. [PDF]

PLoS Genetics, 2014
The steroid hormone ecdysone coordinates insect growth and development, directing the major postembryonic transition of forms, metamorphosis. The steroid-deficient ecdysoneless1 (ecd1) strain of Drosophila melanogaster has long served to assess the ...

JNK signaling coordinates with ecdysone signaling to promote pruning of Drosophila sensory neuron dendrites

Development, 2019
Developmental pruning of axons and dendrites is crucial for the formation of precise neuronal connections, but the mechanisms underlying developmental pruning are not fully understood.
