Pseudopregnancy and aseasonal breeding in dairy goats: genetic basis of fertility and impact on lifetime productivity

Animal, 2018
Until recently, the main selection focus in UK dairy goats has been on milk yield. To develop a selection index suitably weighted for a variety of traits, it is important to understand the genetic relationships between production, health and fertility ...

Prolactin signaling through the short isoform of the mouse prolactin receptor regulates DNA binding of specific transcription factors, often with opposite effects in different reproductive issues [PDF]

, 2009
Background It has been well established that prolactin (PRL) signals through the long form of its receptor (PRL-RL) and activates the Jak/Stat pathway for transcription of PRL target genes.

The Absence of Collagen VI Reduces Systolic Function but Paradoxically Increases Ca2+ Release in the Rat Heart

Acta Physiologica, Volume 242, Issue 1, January 2026.
ABSTRACT Aim Collagen VI has recently been strongly linked to poor outcomes in heart failure through increased endotrophin, a collagen VI‐derived signaling molecule linked to fibrotic remodeling in cardiovascular disease. The mutation of collagen VI can result in Ullrich congenital muscular dystrophy and Bethlem myopathy, pointing to a critical ...

When – and whether – should we spay/neuter companion dogs

Journal of Small Animal Practice, Volume 66, Issue 11, Page 761-766, November 2025.
The recent publication of guidelines for the control of reproduction in dogs and cats shows that a variety of non‐neoplastic and neoplastic conditions occur more commonly in spayed/neutered than entire dogs, and for several of such conditions the earlier the age at surgery – the higher the risk. In addition, unwanted behavioural changes may occur after

A Novel Cultivation System for Germ Cell Proliferation and Sustaining Whole Testicular Niche

Advanced Science, Volume 12, Issue 39, October 20, 2025.
A hydrogel microneedle‐based system enables whole testicular cultivation, supporting spermatogonial proliferation and enhancing spermatogenesis in vitro. This ‘whole testicular spermatogonia pool’ (WTSP) significantly increases spermatid production and fertility potential in mice. This system also promotes spermatogonial expansion in human fetal testes,
