SAV1 in Cooperation With FKBP52 Participates in Implantation

Advanced Science, EarlyView.
The MST‐SAV1 complex modulates FKBP52 phosphorylation to fine‐tune PR activity, ensuring timely uterine transition to receptivity under estrogen signaling for implantation. Stromal SAV1 scaffolds MST1/2‐mediated FKBP52 phosphorylation via noncanonical Hippo to promote PR activity.

Oocyte Quality: Molecular Constituents Altered in the Oocyte Due to Various Environmental Factors [PDF]

, 2016
An estimated 1.6 million American couples struggle with infertility. Some causes for poor fertility can be clearly defined but in many instances, subfertility is unexplained. Poor oocyte quality is now considered to be a main contributing factor for many

Systematic pathway‐level analysis defines conserved transcriptional divergence between primary lung tumors and cell line models

Animal Models and Experimental Medicine, EarlyView.
Lung cancer cell lines diverge substantially from primary tumors at the transcriptional level. Using single‐sample gene set enrichment analysis and L1‐penalized feature selection across TCGA‐LUAD and CCLE‐LUAD, we identified five Hallmark pathways (E2F targets, G2M checkpoint, IFNγ response, coagulation, and EMT) that discriminated primary tumors from ...

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment

The Anatomical Record, EarlyView.
Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

Unraveling ovarian histology: The key morphological aspects that spur the development of the Fossa ovarii in equine

The Anatomical Record, EarlyView.
Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...

EFNA5 as an Oocyte-Derived Factor Enhances Developmental Competence by Modulating Oxidative Stress, Inflammation, and Apoptosis During In Vitro Maturation

Antioxidants
In vitro maturation (IVM) of oocytes remains suboptimal due to oxidative stress and disrupted cumulus–oocyte communication. Oocyte-derived factors (ODFs) are key mediators of this crosstalk and crucial for oocyte competence.

Follicular steroid hormones as markers of oocyte quality and oocyte development potential

Journal of Human Reproductive Sciences, 2014
Various components of follicular fluid are suggested as biochemical predictors of oocyte quality. Previous studies of follicular steroid hormone levels have shown disparate results when related with fertilization outcomes.The objective of the study was to relate the levels of steroid hormones of each individual follicle with oocyte maturation ...

Supraphysiological estradiol levels do not affect oocyte and embryo quality in oocyte donation cycles [PDF]

, 2002
Background: The study aim was to determine whether supraphysiological estradiol (E2) levels reduce oocyte/embryo quality in oocyte donation cycles. Methods: A retrospective analysis of 330 consecutive fresh oocyte donation cycles was performed in an ...

Male reproductive system in stenopodidean shrimps: Unveiling basal reproductive traits in shrimp‐like Pleocyemata (Stenopodidae and Spongicolidae)

The Anatomical Record, EarlyView.
Abstract Stenopodidea represents one of the basal lineages within Pleocyemata, yet the male reproductive system (MRS) of this group remains poorly understood, with limited information available regarding its morphology and function. This study provides the first detailed description of the MRS in four stenopodidean shrimp species from two families ...
