Liver sinusoidal endothelial cells (LSECs) AKA the hepatic sinusoids
They form the lining of the smallest blood vessels in the liver
Juvenile hormone epoxide hydrolase (JHEH) is an enzyme that inactivates insect juvenile hormones
Juvenile hormone epoxide hydrolase (JHEH) is an enzyme that inactivates insect juvenile hormones. This inactivation is accomplished through hydrolysis of the epoxide functional group contained within these hormones into diols. JHEH is one of two enzymes involved in the termination of signaling properties of the various juvenile
The enzyme juvenile hormone esterase catalyzes the hydrolysis of juvenile hormone
The enzyme juvenile hormone esterase (EC 3.1.1.59, systematic name methyl-(2E,6E,10R)-10,11-epoxy-3,7,11-trimethyltrideca-2,6-dienoate acylhydrolase, JH esterase) catalyzes the hydrolysis of juvenile hormone: (1) juvenile hormone I + H2O = juvenile hormone I acid + methanol (2) juvenile hormone III + H2O = juvenile hormone III acid + methanol Nomenclature and function This enzyme belongs to the
The conjugate (10S,11S) JH diol phosphate is the product of a two-step enzymatic process: conversion of JH to JH diol and then addition of a phosphate group to C10

Sex Disparity in Published Studies of IgE-mediated Food Allergy (among children with food allergies, 64.35% were males and 35.65% were females, among adults 34.82% were males and 65.18% were females)
Food allergies are potentially fatal immune-mediated disorders that are growing globally. The relationship between sex and food allergy remains incompletely understood. Here we tested the hypothesis that, should sex influence the clinical response to food allergens, this would be reflected
Growth regulator may refer to growth hormone, insect growth regulator (insecticide) or plant hormone (herbicide)
Growth hormone, stimulates growth in humans and other animals Insect growth regulator, used as insecticides Plant hormone, used to control the growth of weeds
The ecdysone receptor is a nuclear receptor found in arthropods, where it controls development and contributes to other processes such as reproduction
The receptor is a non-covalent heterodimer of two proteins, the EcR protein and ultraspiracle protein (USP). These nuclear hormone receptor proteins are the insect orthologs of the mammalian farnesoid X receptor (FXR) and retinoid X receptor (RXR) proteins, respectively. It binds to and is activated by ecdysteroids. Insect ecdysone receptors are currently better characterized
Juvenile hormone (and Methoprene)
Juvenile hormones (JHs) are a group of acyclic sesquiterpenoids that regulate many aspects of insect physiology. The first discovery of a JH was by Vincent Wigglesworth. JHs regulate development, reproduction, diapause, and polyphenisms. The chemical formula for juvenile hormone is C18H30O3. Riddiford, L. M. (1994). "Cellular and molecular actions
Cleavage (embryology)
In embryology, cleavage is the division of cells in the early development of the embryo, following fertilization. The zygotes of many species undergo rapid cell cycles with no significant overall growth, producing a cluster of cells the same size as the original zygote. The different cells derived from cleavage are called blastomeres and form

The PVN Powerhouse: How the Paraventricular Nucleus Rules Hormone Secretion
Hold onto your hypothalamus, folks! We're about to dive into the wild world of the Paraventricular Nucleus (PVN), where tiny cells pack a mighty hormonal punch! Picture this: deep in the brain's control center, the hypothalamus, sits the PVN - a
Vitellogenin is a precursor of egg yolk that transports protein and some lipid from the liver through the blood to the growing oocytes where it becomes part of the yolk. Normally, it is only found in the blood or hemolymph of females…
Vitellogenin (VTG or less popularly known as VG) (from Latin vitellus, yolk, and genero, I produce) is a precursor of egg yolk that transports protein and some lipid from the liver through the blood to the growing oocytes where it becomes part of the yolk. Normally,
Vitellin is essential in the fertilization process, and embryonic development in egg-laying organisms
Vitellin is a protein found in the egg yolk. It is a phosphoprotein. Vitellin is a generic name for major of many yolk proteins. Vitellins at the U.S. National Library of Medicine Medical Subject Headings (MeSH) KUNKEL, JOSEPH G.; JOHN H. NORDIN (1985). "Yolk Proteins. 2.2 Vitellin, the major
Protein phosphorylation was first reported in 1906
Protein phosphorylation is a reversible post-translational modification of proteins in which an amino acid residue is phosphorylated by a protein kinase by the addition of a covalently bound phosphate group. Phosphorylation alters the structural conformation of a protein, causing it to become activated, deactivated, or otherwise modifying its function. Approximately 13,000 human proteins have
Phosphorylation
In biochemistry, phosphorylation is the attachment of a phosphate group to a molecule or an ion.[1] This process and its inverse, dephosphorylation, are common in biology.[2] Protein phosphorylation often activates (or deactivates) many enzymes.[3][4] During respiration and photosynthesis Phosphorylation is essential to the processes of both anaerobic and aerobic respiration, which involve the production of adenosine triphosphate (ATP),
