The Colour Changes In Lizards, Particularly In Phrynosoma [PDF]

open access: yes, 1938
The activities of the melanophore system of Phrynosoma in comparison with that of Chamaeleo may be stated categorically in the following way. I. The blanching of Phrynosoma blainvillii is due (1) to the action of its concentrating nerve-fibres on ...

The Pivotal Role of GR‐CAR Pathway in Fetal Programming of Hepatic Cytochrome P450 3A Alteration in Adulthood

open access: yesAdvanced Science, EarlyView.
Prenatal dexamethasone exposure (PDE) persistently upregulates hepatic CYP3A1/CYP2B1 in offspring via glucocorticoid receptor (GR) activation. In vivo and in vitro studies show GR promotes P300/CBP binding to the constitutive androstane receptor (CAR) promoter, sustaining histone acetylation (H3K9/K27ac) and enhancing CYP expression. The GR–CAR pathway

Identification and Profiling of Pituitary microRNAs of Sheep during Anestrus and Estrus Stages

open access: yesAnimals, 2020
MicroRNAs (miRNAs) are a class of small non-coding RNAs, molecules of 21 to 25 nucleotides in length, that regulate gene expression by binding to their target mRNA and play a significant role in animal development.

Migrasomes in Ischemic Stroke: Molecular Landscape and Pathophysiological Impact

open access: yesAdvanced Science, EarlyView.
Multi‐omics profiling of stroke patients exposes systemic molecular fingerprints of immune activation, oxidative stress and metabolic collapse. Complement and coagulation cascade, and cholesterol metabolism emerge as shared functional hallmarks of plasma migrasomes in stroke patients and migrasomes isolated from experimental stroke mice.

TBX3‐ Related Disorder

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous pathogenic variants in TBX3 cause Ulnar‐Mammary syndrome (UMS). The phenotype is classically characterized by upper limb defects, apocrine/mammary gland hypoplasia, hypogonadism, and various midline defects. However, the clinical spectrum is highly variable, and some individuals may present with a mild or atypical presentation ...

Impact of Ovariectomy on the Anterior Pituitary Gland in Female Rats

open access: yesInternational Journal of Endocrinology, 2023
Ovariectomy (OVX) causes a depletion of circulating estradiol (E2) and influences hypothalamic kisspeptin neurons, which govern gonadotropin-releasing hormone (GnRH) release and ultimately gonadotropin secretion.
