Regulation of 3β-Hydroxysteroid Dehydrogenase/∆5-∆4 Isomerase: A Review [PDF]

open access: yes, 2013
This review focuses on the expression and regulation of 3β-hydroxysteroi ddehydrogenase/Δ5-Δ4 isomerase (3β-HSD), with emphasis on the porcine version. 3β-HSD is often associated with steroidogenesis, but its function in the metabolism of both steroids ...

LRRC4 Deficiency Drives Premature Ovarian Insufficiency by Disrupting Metabolic Homeostasis in Granulosa Cells

open access: yesAdvanced Science, EarlyView.
LRRC4 deficiency disrupts the metabolic homeostasis of mitochondrial aerobic respiration and glycolysis during GC differentiation by inhibiting the ubiquitination‐mediated degradation of YAP, which ultimately leads to POI. These findings reveal the novel molecular etiology of POI and provide a promising target for prevention and treatment.

Transcriptional and posttranscriptional regulation of human androgen receptor expression by androgen. [PDF]

open access: yes, 1993
Autoregulation is a control mechanism common to several proteins of the steroid/thyroid hormone receptor superfamily. In this work the effect of androgens and antiandrogens on the expression of the human androgen receptor (hAR) in prostate and breast ...

FABP4 as a Mediator of Lipid Metabolism and Pregnant Uterine Dysfunction in Obesity

open access: yesAdvanced Science, EarlyView.
Obesity during late pregnancy contributes to uterine smooth muscle dysfunction, but the underlying mechanisms are unclear. This study identifies fatty acid binding protein 4 (FABP4) as a key player in the process, mediating excessive fatty acid uptake, lipid accumulation, and mitochondrial dysfunction in myometrial cells. FABP4 could be a novel uterine

Steroid receptor expression in the fish inner ear varies with sex, social status, and reproductive state [PDF]

open access: yes, 2010
Background Gonadal and stress-related steroid hormones are known to influence auditory function across vertebrates but the cellular and molecular mechanisms responsible for steroid-mediated auditory plasticity at the level of the inner ear remain unknown.

Testosterone Delays Bone Microstructural Destruction via Osteoblast‐Androgen Receptor‐Mediated Upregulation of Tenascin‐C

open access: yesAdvanced Science, EarlyView.
This study reveals that Testosterone–Androgen Receptor signaling delays elderly male bone destruction by upregulation of the osteoblastic extracellular tenascin‐C (TNC). The osteoprotective effect of fibrinogen C‐terminus of TNC is demonstrated in male osteoporotic mice model that osteoblast‐specific Ar‐knockout, potentially via inhibition of ...

Cartilage‐Penetrating Framework Nucleic Acid Nanoparticles Ameliorate Osteoarthritis by Promoting Drug Delivery and Chondrocyte Uptake

open access: yesAdvanced Science, EarlyView.
Based on the poor cartilage penetration of tFNA, a novel tFNA‐2WL with excellent cartilage permeability and perfect chondrocyte endocytosis properties is designed and fabricated. As a result, tFNA‐2WL has a nearly seven‐fold increase in the penetration depth into the cartilage, with the same excellent cell entry properties as tFNA.

Catechol estrogens stimulate insulin secretion in pancreatic β-cells via activation of the transient receptor potential A1 (TRPA1) channel [PDF]

open access: yes, 2019
Estrogen hormones play an important role in controlling glucose homeostasis and pancreatic β-cell function. Despite the significance of estrogen hormones for regulation of glucose metabolism, little is known about the roles of endogenous estrogen ...

An Off‐the‐Shelf Artificial Blood Clot Hydrogel Neutralizing Multiple Proinflammatory Mediators for Pro‐Regenerative Periodontitis Treatment

open access: yesAdvanced Science, EarlyView.
CCS‐RSF@PRP hydrogel is engineered to structurally and functionally mimic the blood clot by integrating PPR, CCS, and RSF nanofibers through in situ activation of PRP. In a rat periodontitis model, CCS‐RSF@PRP hydrogel effectively promotes periodontal tissue repair, attributing to neutralizing the multiple proinflammatory mediators, thus rebuilding a ...

The direct response of the gonads to cues of stress in a temperate songbird species is season-dependent. [PDF]

open access: yes, 2013
The gonadotropin releasing hormone (GnRH) system in the hypothalamus is often considered the final point in integration of environmental cues as they pertain to the reproductive axis.
