Spheroids as a model for endometriotic lesions

open access: yesJCI Insight, 2023
The development and progression of endometriotic lesions are poorly understood, but immune cell dysfunction and inflammation are closely associated with the pathophysiology of endometriosis.

Regulatory T cells are paramount effectors in progesterone regulation of embryo implantation and fetal growth

open access: yesJCI Insight, 2023
Progesterone (P4) is essential for embryo implantation, but the extent to which the pro-gestational effects of P4 depend on the maternal immune compartment is unknown.

Signaling through retinoic acid receptors is essential for mammalian uterine receptivity and decidualization

open access: yesJCI Insight, 2021
Retinoic acid (RA) signaling has long been speculated to regulate embryo implantation, because many enzymes and proteins responsible for maintaining RA homeostasis and transducing RA signals are tightly regulated in the endometrium during this critical ...

Reproductive biology of Bellucia (MELASTOMATACEAE) [PDF]

open access: yesActa Amazonica, 1986
The reproductive biology of five of the seven species of Bellucia (Melastomataceae), a genus of shrubs and small trees, was investigated in Amazonia. Sucessful fruit-set by Bellucia requires floral visitation by bees.

WNK1 regulates uterine homeostasis and its ability to support pregnancy

open access: yesJCI Insight, 2020
WNK1 (with no lysine [K] kinase 1) is an atypical kinase protein ubiquitously expressed in humans and mice. A mutation in its encoding gene causes hypertension in humans, which is associated with abnormal ion homeostasis.

Loss-of-function mutations in CFAP57 cause multiple morphological abnormalities of the flagella in humans and mice

open access: yesJCI Insight, 2023
Multiple morphological abnormalities of the sperm flagella (MMAF) are the most severe form of asthenozoospermia due to impaired axoneme structure in sperm flagella. Dynein arms are necessary components of the sperm flagellar axoneme.

Transcriptome and DNA methylome analyses reveal underlying mechanisms for the racial disparity in uterine fibroids

open access: yesJCI Insight, 2022
Uterine fibroids (leiomyomas) affect Black women disproportionately compared with women of other races and ethnicities in terms of prevalence, incidence, and severity of symptoms. The causes of this racial disparity are essentially unknown.

Notes on the floral sexuality of some species of the tree genus Triplaris (Polygonaceae)

open access: yesCaldasia, 2021
The majority of angiosperms (~94 %) are synoecious, with only a small minority separating the pro-duction of the two gamete types onto different biological individuals (dioecy).

ARRDC5 expression is conserved in mammalian testes and required for normal sperm morphogenesis

open access: yesNature Communications, 2023
In sexual reproduction, sperm contribute half the genomic material required for creation of offspring yet core molecular mechanisms essential for their formation are undefined.

A review of the reproductive system in anuran amphibians

open access: yesZoological Letters, 2023
Reproductive biology is an important topic that is well explored in many vertebrates, but information about frogs’ reproductive mechanisms could be improved.
