Farnesol-like endogenous sesquiterpenoids in vertebrates: the probable but overlooked functional "inbrome" anti-aging counterpart of juvenile hormone of insects?.

Frontiers in endocrinology

De Loof A, Marchal E, Rivera-Perez C, Noriega FG, Schoofs L.
PMID: 25610425
Front Endocrinol (Lausanne). 2015 Jan 06;5:222. doi: 10.3389/fendo.2014.00222. eCollection 2014.

Literature on the question whether the juvenile stage of vertebrates is hormonally regulated is scarce. It seems to be intuitively assumed that this stage of development is automated, and does not require any specific hormone(s). Such reasoning mimics the...

Cloning and structural characterization of juvenile hormone diol kinase in Spodoptera litura.

Insect science

Zeng BJ, Lv Y, Zhang LL, Huang LH, Feng QL.
PMID: 29080335
Insect Sci. 2017 Oct 28; doi: 10.1111/1744-7917.12553. Epub 2017 Oct 28.

Juvenile hormone (JH) is one of key insect hormones that regulate metamorphosis. Juvenile hormone diol kinase (JHDK) is an enzyme involved in JH metabolism and catalyzes JH diol to form a polar end product, JH diol phosphate that has...

Intraluminal Farnesol and Farnesal in the Mealworm's Alimentary Canal: An Unusual Storage Site Uncovering Hidden Eukaryote Ca.

Frontiers in endocrinology

Front Endocrinol (Lausanne). 2019 Dec 19;10:885. doi: 10.3389/fendo.2019.00885. eCollection 2019.

Farnesol, the sesquiterpenoid precursor of the six presently known insect juvenile hormones (JHs) was for the first time chemically identified in 1961, not in JH synthesizing glands or whole body extracts, but in excrements of the mealworm

Insulin and Neuroparsin Promote Neurite Outgrowth in Cultured Locust CNS.

The European journal of neuroscience

Vanhems E, Delbos M, Girardie J.
PMID: 12106278
Eur J Neurosci. 1990;2(9):776-782. doi: 10.1111/j.1460-9568.1990.tb00468.x.

Organotypic cultures of locust embryo central nervous system (CNS) were used to study the influence of hormonal factors on neurite outgrowth. Explants from the third thoracic ganglion (embryonic day 9) were grown in a serum-free medium and exposed to...

Reconstruction of insect hormone pathways in an aquatic firefly, .

PMID: 31396456
PeerJ. 2019 Aug 02;7:e7428. doi: 10.7717/peerj.7428. eCollection 2019.

Insect hormones: ecdysteroids and juvenile hormones have crucial functions during the regulation of different developmental pathways in insects. Insect metamorphosis is one of the primary pathways regulated by these hormones. The insect hormone biosynthetic pathway is conserved among arthropods,...

Role of hormones in starvation-induced delay in larval hemolymph protein gene expression in Galleria mellonella.

Roux's archives of developmental biology : the official organ of the EDBO

Memmel NA, Ray A, Kumaran AK.
PMID: 28305475
Rouxs Arch Dev Biol. 1988 Jan;197(8):496-502. doi: 10.1007/BF00385683.

Developmental Northern analysis of larval hemolymph protein gene transcripts in Galleria mellonella showed that Lhp76 is expressed all through the larval life, while Lhp82 is expressed only during the last larval stadium. Neither transcript was detectable in pharate adults...

Detoxification gene families in Phylloxera: Endogenous functions and roles in response to the environment.

Comparative biochemistry and physiology. Part D, Genomics & proteomics

Chertemps T, Le Goff G, Maïbèche M, Hilliou F.
PMID: 34246923
Comp Biochem Physiol Part D Genomics Proteomics. 2021 Dec;40:100867. doi: 10.1016/j.cbd.2021.100867. Epub 2021 Jun 25.

Phylloxera, Daktulosphaira vitifoliae, is an agronomic pest that feeds monophagously on grapevine, Vitis spp. host plants. Phylloxera manipulates primary and secondary plant metabolism to establish either leaf or root galls. We manually annotated 198 detoxification genes potentially involved in...

The Effect of Nutritional Supplements on Muscle-Derived Stem Cells in vitro.

International journal of stem cells

Fernyhough ME, Bucci LR, Feliciano J, Dodson MV.
PMID: 24855542
Int J Stem Cells. 2010 May;3(1):63-7. doi: 10.15283/ijsc.2010.3.1.63.

Postnatal muscle stem cells, recognized as myogenic satellite cells, were isolated from sheep skeletal muscle and used in these experiments. Forty-one different metabolic compounds that are commonly found in commercially-available oral supplements were exposed to primary muscle stem cell...

Mode of Action of Farnesol, the "Noble Unknown" in Particular in Ca.

Frontiers in neuroscience

De Loof A, Schoofs L.
PMID: 30858798
Front Neurosci. 2019 Feb 25;13:141. doi: 10.3389/fnins.2019.00141. eCollection 2019.

Farnesol, the sesquiterpenoid precursor of insect juvenile hormones (JH) that itself has JH activity, existed already long before animals and their hormones came into being. Although it is omnipresent in all eukaryotes, this molecule remains a "noble unknown" in...

Eat to reproduce: a key role for the insulin signaling pathway in adult insects.

Frontiers in physiology

Badisco L, Van Wielendaele P, Vanden Broeck J.

Insects, like all heterotrophic organisms, acquire from their food the nutrients that are essential for anabolic processes that lead to growth (larval stages) or reproduction (adult stage). In adult females, this nutritional input is processed and results in a...
