Genetics tools for corpora allata specific gene expression in Aedes aegypti mosquitoes [PDF]

open access: yesScientific Reports, 2022
Juvenile hormone (JH) is synthesized by the corpora allata (CA) and controls development and reproduction in insects. Therefore, achieving tissue-specific expression of transgenes in the CA would be beneficial for mosquito research and control. Different

Farnesyl phosphatase, a Corpora allata enzyme involved in juvenile hormone biosynthesis in Aedes aegypti. [PDF]

open access: yesPLoS ONE, 2013
The juvenile hormones (JHs) are sesquiterpenoid compounds that play a central role in insect reproduction, development and behavior. The late steps of JH III biosynthesis in the mosquito Aedes aegypti involve the hydrolysis of farnesyl pyrophosphate (FPP)

Negative Feedbacks by Isoprenoids on a Mevalonate Kinase Expressed in the Corpora Allata of Mosquitoes. [PDF]

open access: yesPLoS ONE, 2015
Juvenile hormones (JH) regulate development and reproductive maturation in insects. JHs are synthesized through the mevalonate pathway (MVAP), an ancient metabolic pathway present in the three domains of life.

Differential gene expression and microRNA profile in corpora allata-corpora cardiaca of Aedes aegypti mosquitoes with weak juvenile hormone signalling [PDF]

open access: yesBMC Genomics
The corpora allata-corpora cardiaca (CA-CC) is an endocrine gland complex that regulates mosquito development and reproduction through the synthesis of juvenile hormone (JH). Epoxidase (Epox) is a key enzyme in the production of JH.

Juvenile hormone biosynthesis gene expression in the corpora allata of honey bee (Apis mellifera L.) female castes. [PDF]

open access: yesPLoS ONE, 2014
Juvenile hormone (JH) controls key events in the honey bee life cycle, viz. caste development and age polyethism. We quantified transcript abundance of 24 genes involved in the JH biosynthetic pathway in the corpora allata-corpora cardiaca (CA-CC ...

Lithium salts alter the size and morphology of the Madagascar hissing cockroach’s neuroendocrine system [PDF]

open access: yesScientific Reports
Lithium salts have been used in psychiatry for decades as normothymics. The full mechanism of action of these drugs is not yet known. The limited work on lithium suggests that it may affect brain structure and size in humans and animals. This study aimed

Peptidomic Analysis of the Brain and Corpora Cardiaca-Corpora Allata Complex in the Bombyx mori [PDF]

open access: yesInternational Journal of Peptides, 2012
The silkworm, Bombyx mori, is an important economic insect for silk production. However, many of the mature peptides relevant to its various life stages remain unknown. Using RP-HPLC, MALDI-TOF MS, and previously identified peptides from B. mori and other insects in the transcriptome database, we created peptide profiles showing a total of 6 ion masses

The effect of ovary implants on juvenile hormone production by corpora allata of male Diploptera punctata [PDF]

open access: yesJournal of Insect Science, 2003
In the cockroach Diploptera punctata, vitellogenic basal oocytes stimulate juvenile hormone production by the corpora allata. Experiments with males were designed to determine whether oocytes must grow vitellogenically in order to stimulate juvenile ...

Tissue-specific transcriptomic and endocrine signatures of obligatory reproductive diapause in Eurygaster integriceps [PDF]

open access: yesScientific Reports
Obligatory reproductive diapause is a hormonally regulated, developmentally programmed state occurring independently of environmental cues. Despite its prevalence in univoltine insects, the molecular regulation remains unclear.

Ovarian transcriptome analyses indicate that weak juvenile hormone signaling underlies the molecular basis of oogenesis deficiencies in mosquitoes [PDF]

open access: yesBMC Biology
Background Juvenile hormone (JH) is synthesized by the corpora allata (CA) and controls development and reproduction in insects. We recently used CRISPR/Cas9 to establish a line lacking the enzyme that catalyzes the final step of JH biosynthesis in ...
