Complications Associated with Uterine Artery Embolisation for Fibroids

open access: yesObstetrics and Gynecology International, 2012
Uterine artery embolisation (UAE) is a relative newcomer to the mainstream treatment modalities available for fibroid-related problems. The efficacy of UAE is indisputable and has been shown to be comparable to hysterectomy in the short term in large ...

Protocadherin-1 is expressed in the notochord of mouse embryo but is dispensable for its formation

open access: yesBiochemistry and Biophysics Reports, 2021
Notochord is an embryonic midline structure that serves as mechanical support for axis elongation and the signaling center for the surrounding tissues.

A Tale of Division and Polarization in the Mammalian Embryo [PDF]

open access: yesDevelopmental Cell, 2017
The first cell fate choice in mouse development is the segregation of the embryonic inner cell mass and the extra-embryonic trophectoderm. In this issue of Developmental Cell, Korotkevic and colleagues (2017) show that the interplay between cell polarization and cell-cell contact drives the segregation of these lineages, providing a framework for self ...

The p66(Shc) adaptor protein controls oxidative stress response in early bovine embryos. [PDF]

open access: yesPLoS ONE, 2014
The in vitro production of mammalian embryos suffers from high frequencies of developmental failure due to excessive levels of permanent embryo arrest and apoptosis caused by oxidative stress.

Non-random chromosome positioning in mammalian sperm nuclei, with migration of the sex chromosomes during late spermatogenesis. [PDF]

open access: yes, 2005
Chromosomes are highly organized and compartmentalized in cell nuclei. The analysis of their position is a powerful way to monitor genome organization in different cell types and states.

Telomere lengths in human oocytes, cleavage stage embryos and blastocysts [PDF]

open access: yes, 2010
Telomeres are repeated sequences that protect the ends of chromosomes and harbour DNA-repair proteins. Telomeres shorten during each cell division in the absence of telomerase.

Asynchronous mouse embryo polarization leads to heterogeneity in cell fate specification

open access: yeseLife
The first lineage allocation in mouse and human embryos separates the inner cell mass (ICM) from the outer trophectoderm (TE). This symmetry-breaking event is executed through polarization of cells at the 8 cell stage and subsequent asymmetric divisions,

Epigenetic regulation in mammalian preimplantation embryo development

open access: yesReproductive Biology and Endocrinology, 2009
Preimplantation embryo development involves four stages: fertilization, cell cleavage, morula and blastocyst formation. During these stages, maternal and zygotic epigenetic factors play crucial roles.

Reorganization, specialization, and degradation of oocyte maternal components for early development

open access: yesReproductive Medicine and Biology, 2023
Background Oocyte components are maternally provided, solely determine oocyte quality, and coordinately determine embryo quality with zygotic gene expression.

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.
