Exploring the Stress Impact in the Paternal Germ Cells Epigenome: Can Catecholamines Induce Epigenetic Reprogramming?

open access: yesFrontiers in Endocrinology, 2021
Spermatogenesis is characterized by unique epigenetic programs that enable chromatin remodeling and transcriptional regulation for proper meiotic divisions and germ cells maturation. Paternal lifestyle stressors such as diet, drug abuse, or psychological

A new common functional coding variant at the DDC gene change renal enzyme activity and modify renal dopamine function. [PDF]

open access: yes, 2019
The intra-renal dopamine (DA) system is highly expressed in the proximal tubule and contributes to Na+ and blood pressure homeostasis, as well as to the development of nephropathy.

Norepinephrine Induces Sertoli Cell Ferroptosis via Receptors Desensitization Causing Stress‐Related Male Reproductive Dysfunction

open access: yesAdvanced Science, EarlyView.
Psychological stress activates the sympathetic–adrenal axis, elevating norepinephrine (NE) and suppressing reproductive hormones, thereby impairing male reproduction. Excess NE overactivates and desensitizes β‐adrenergic receptors (β‐ARs), triggering Sertoli cell ferroptosis and disrupting spermatogenesis.

α1D-Adrenoceptors are responsible for the high sensitivity and the slow time-course of noradrenaline-mediated contraction in conductance arteries [PDF]

open access: yes, 2013
The objective of this study was to determine whether the different time-course characteristics of α1-adrenoceptor-mediated contraction in arteries can be related to the subtypes involved.

Stress‐Induced Activation of Prolactin‐NR4A1‐Midkine Axis Exacerbates Skin Inflammation

open access: yesAdvanced Science, EarlyView.
Chronic psychological stress activates prolactin signaling to reprogram dermal fibroblasts into APCDD1+ inflammatory effectors via NR4A1, driving midkine secretion. This paracrine hub amplifies keratinocyte proliferation and immune recruitment, thus exacerbating skin inflammation.

The Effect of a Reduced-Calorie Diet on alpha-2 Adrenergic Receptor Responsiveness in Abdominal Adipose Tissue in Obese Men During Exercise [PDF]

open access: yes, 2008
There is at present an imperfect understanding of the effect of diet on availability of inhibitory receptors in fat cells during exercise among obese men. *Objective:* The purpose of this study was to determine whether diet results in

The Effect of High Dose Total Body Irradiation on ACTH, Corticosterone, and Catecholamines in the Rat [PDF]

open access: yes, 2011
Total body irradiation (TBI) or partial body irradiation is a distinct risk of accidental, wartime, or terrorist events. Total body irradiation is also used as conditioning therapy before hematopoietic stem cell transplantation.
