Dietary L‐Tyrosine Sustains Egg Production and Quality by Modulating Promoter CpG Methylation, Gene Expression, and Hormone Profiles in Reproductive Signalling Pathways of Aged Laying Hens

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Managing prolactin (PRL)‐mediated reproductive suppression is critical for maintaining egg production in commercial laying hens. L‐tyrosine (TYR), a precursor of dopamine (DA), may counteract age‐related reproductive decline by suppressing PRL, thereby sustaining productivity and egg quality in late‐phase laying hens.

Gut microbiota-gonadal axis: the impact of gut microbiota on reproductive functions

Frontiers in Immunology
The influence of gut microbiota on physiological processes is rapidly gaining attention globally. Despite being under-studied, there are available data demonstrating a gut microbiota-gonadal cross-talk, and the importance of this axis in reproduction ...

Influence of oestradiol on exercise induced muscular damage and heart rate variability in a non‐trained healthy population

Experimental Physiology, EarlyView.
Abstract This study evaluates in non‐trained healthy women the influence of oestradiol (E2) on exercise induced muscular damage (EIMD) and performance. Thirty‐six young healthy women performed a step‐exercise until exhaustion, assessing the number of repetitions, pain perception and well‐being (questionnaires, 15 min and at 48 h post‐exercise), blood ...

Intramuscular pathways of maladaptation in overtraining syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...

Steroidogenic differentiation of human amniotic membrane-derived mesenchymal stem cells into a progesterone-/androgen-producing cell lineage by SF-1 and an estrogen-producing cell lineage by WT1−KTS

Frontiers in Endocrinology
BackgroundSex steroid hormones, primarily synthesized by gonadal somatic cells, are pivotal for sexual development and reproduction. Mice studies have shown that two transcription factors, steroidogenic factor 1 (SF-1) and Wilms’ tumor 1 (WT1), are ...

Endocrine and androgenic response to altitude training in professional cyclists

The Journal of Physiology, EarlyView.
Abstract figure legend Steroidal and endocrine variables are altered during altitude training. Abstract This study investigated endocrine and steroidal blood markers in 31 male elite cyclists monitored over 7 weeks, including a 3 week altitude training camp either at 2050 m (n = 19) or 3000 m (n = 12).
