The lipid peroxidation product 4-hydroxynonenal contributes to oxidative stress-mediated deterioration of the ageing oocyte

open access: yesScientific Reports, 2017
An increase in intraovarian reactive oxygen species (ROS) has long been implicated in the decline in oocyte quality associated with maternal ageing. Oxidative stress (OS)-induced lipid peroxidation and the consequent generation of highly electrophilic ...

Mapping the Non‐Canonical Splicing Variants: Decrypting the Hidden Genetic Architecture of Idiopathic Male Infertility

open access: yesAdvanced Science, EarlyView.
This study highlights the significance of non‐canonical splicing variants in male infertility, a factor often overlooked during the analysis of high‐throughput sequencing data. Incorporating the non‐canonical splicing variants prioritization in the genetic analysis pipeline will increase the genetic diagnosis of patients with male infertility ...

Soft Micromanipulation Robot for Real‐Time Adaptive Multimodal Operation

open access: yesAdvanced Science, EarlyView.
This manuscript proposes a soft micromanipulator robot (SMR) for “full‐angle” precision biomedical operations. Bio‐inspired SMR achieves omnidirectional motion, micrometer precision, and multimodal capabilities including aspiration, transfer, rotation, assembly, injection, and cutting.

Disruption of ovarian function and induction of apoptosis in female mice by Brefeldin A: Mechanistic insights into reproductive toxicity

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Brefeldin A (BFA) significantly inhibits oocyte release and induces apoptosis in ovarian granulosa cells by disrupting follicular development. It downregulates proliferation‐associated genes, reduces SIRT1/SIRT6 proteins, and upregulates cell cycle inhibitors P21 and P16. Additionally, BFA impairs estrogen synthesis and affects ovarian function through

The Role of Oocyte Organelles in Determining Developmental Competence

open access: yesBiology, 2017
The ability of an oocyte to undergo successful cytoplasmic and nuclear maturation, fertilization and embryo development is referred to as the oocyte’s quality or developmental competence.

Generating golden Syrian hamsters with conditional alleles via zygote microinjection of CRISPR/Cas9

open access: yesAnimal Models and Experimental Medicine, EarlyView.
We established the first conditional knockout (cKO) model in the golden Syrian hamster by CRISPR/Cas9‐mediated genome editing. Cas9 protein, two sgRNAs, and a donor plasmid carrying loxP‐flanked exon 2 of the ApoF gene were microinjected into one‐cell embryos. The floxed allele was efficiently generated (up to 27%) and transmitted through the germline.

Equilibrium between anti‐oxidants and reactive oxygen species: a requisite for oocyte development and maturation

open access: yesReproductive Medicine and Biology, 2016
Reactive oxygen species (ROS) are required for cellular functioning and are controlled by anti‐oxidants. The ROS influence the follicles, oocytes, endometrium, and their environment.
