Disruptive Effects of Two Curcuminoids (Demethoxycurcumin and Bisdemethoxycurcumin) on the Larval Development of Drosophila melanogaster

open access: yesInsects, 2023
Juvenile hormones (JHs) play a central role in insect development, reproduction, and various physiological functions. Curcuminoids generally exhibit a wide range of biological activities, such as antioxidant, anti-inflammatory, antibacterial, and ...

Suppression of Gene Juvenile Hormone Diol Kinase Delays Pupation in Heortia vitessoides Moore

open access: yesInsects, 2019
Juvenile hormone diol kinase (JHDK) is a critical enzyme involved in juvenile hormone degradation in insects. In this study, HvJHDK in the Heortia vitessoides Moore (Lepidoptera: Crambidae) transcriptional library was cloned.

Functional characterization of a juvenile hormone esterase related gene in the moth Sesamia nonagrioides through RNA interference. [PDF]

open access: yesPLoS ONE, 2013
Juvenile hormone esterase (JHE) is a carboxylesterase that has attracted great interest because of its critical role in regulating larval to adult transition in insects and other arthropods.

Juvenile Hormone Studies in Drosophila melanogaster

open access: yesFrontiers in Physiology, 2022
In the field of insect endocrinology, juvenile hormone (JH) is one of the most wondrous entomological terms. As a unique sesquiterpenoid hormone produced and released by the endocrine gland, corpus allatum (CA), JH is a critical regulator in multiple ...

Analysis of genes expression of Spodoptera exigua larvae upon AcMNPV infection. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: The impact of Autographa californica multicapsid nucleopolyhedrovirus (AcMNPV) infection on host gene expression in Spodoptera exigua 4th instar larvae was investigated through the use of 454 sequencing-based RNA-seq of cDNA libraries ...

Abnormal development in larvae of Sesamia nonagrioides (Lepidoptera: Noctuidae) resulting from baculovirus-mediated overexpression of a JHE-related gene (SnJHER)

open access: yesEuropean Journal of Entomology, 2017
The Mediterranean corn borer Sesamia nonagrioides (Lepidoptera: Noctuidae) has a unique and recently multiplied juvenile hormone esterase gene family (SnJHER) with particular transcriptional profiles and functional characteristics.

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

open access: yesMemorias 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.

Skeletal manifestations of juvenile hypothyroidism and the impact of treatment on skeletal system

open access: yesIndian Journal of Endocrinology and Metabolism, 2013
Thyroid hormone mediates growth and development of the skeleton through its direct effects and through its permissive effects on growth hormone. The effect of hypothyroidism on bone is well described in congenital hypothyroidism, but the impact of ...

Juvenile Hormone Induction of Esterases: A Mechanism for the Regulation of Juvenile Hormone Titer [PDF]

open access: yesProceedings of the National Academy of Sciences, 1972
Within a few hours after injection of juvenile hormone into Hyalophora gloveri pupae, several fast-migrating carboxylesterases (EC 3.1.1.1) that are sensitive to di iso propylfluorophosphate appear in the hemolymph.
