The consequences of nuclear transfer for mammalian foetal development and offspring survival : a mitochondrial DNA perspective [PDF]

, 2004
Review of the articleThe introduction of nuclear transfer (NT) and other technologies that involve embryo reconstruction require us to reinvestigate patterns of mitochondrial DNA (mtDNA) transmission, transcription and replication.

The Influence of Socio-Cultural Factors on Oocyte Donors' Motivations and Disclosure Decisions

Changing Societies & Personalities, 2022
The study focuses on the motivations of Russian oocyte donors and the socio-cultural factors affecting these motivations. We conducted 16 semi-structured interviews with actual or prospective oocyte donors.

Embryo donation families : mothers' decisions regarding disclosure of donor conception [PDF]

BACKGROUND: Previous data suggest that parents who adopt a child tend to support full disclosure while donor conception families prefer to keep the method of conception relatively private.

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Cleavage Stage versus Blastocyst Stage Embryo Transfer in Oocyte Donation Cycles

Medicina, 2019
Background and Objective: During the last few years, a trend has been noted towards embryos being transferred at the blastocyst stage, which has been associated with improved rates regarding implantation and clinical pregnancy in comparison to cleavage ...

Regulated mitochondrial DNA replication during oocyte maturation is essential for successful porcine embryonic development. [PDF]

, 2006
Cellular ATP is mainly generated through mitochondrial oxidative phosphorylation, which is dependent on mitochondrial DNA (mtDNA). We have previously demonstrated the importance of oocyte mtDNA for porcine and human fertilization.

Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

FEBS Open Bio, EarlyView.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...
