Dynamic Changes in Proteome during Yak Oocyte Maturation Analyzed Using iTRAQ Technology

open access: yesAnimals, 2023
The aim of this study was to investigate protein regulation at different time points during the in vitro maturation of yak oocytes. Yak oocytes at GV, MI, and MII stages were collected during in vitro maturation, and differential proteomics sequencing ...

Active mechanics reveal molecular-scale force kinetics in living oocytes [PDF]

open access: yesBiophysical Journal 114,7, 1667(2018), 2015
Active diffusion of intracellular components is emerging as an important process in cell biology. This process is mediated by complex assemblies of molecular motors and cytoskeletal filaments that drive force generation in the cytoplasm and facilitate enhanced motion. The kinetics of molecular motors have been precisely characterized in-vitro by single

Executive Privilege in the Federal Courts [PDF]

open access: yes, 1962
Apoptosis is one type of programmed cell death, important during tissue development and to maintain the tissue homeostasis. Apoptosis comprises a complex network of internal signaling pathways, and an important part of this signaling network is the ...

Cortical microtubule nucleation can organise the cytoskeleton of $Drosophila$ oocytes to define the anteroposterior axis [PDF]

open access: yeseLife 4, e06088 (2015), 2015
Many cells contain non-centrosomal arrays of microtubules (MT), but the assembly, organisation and function of these arrays are poorly understood. We present the first theoretical model for the non-centrosomal MT cytoskeleton in $Drosophila$ oocytes, in which $bicoid$ and $oskar$ mRNAs become localised to establish the anterior-posterior body axis ...

Fatty Acid Oxidation and Meiotic Resumption in Mouse Oocytes [PDF]

open access: yes, 2009
We have examined the potential role of fatty acid oxidation (FAO) in AMP-activated protein kinase (AMPK)-induced meiotic maturation. Etomoxir and malonyl CoA, two inhibitors of carnitine palmitoyl transferase-1 (CPT1), and thus FAO, blocked meiotic ...

Cryopreservation of equine oocytes: looking into the crystal ball [PDF]

open access: yes, 2020
In vitro embryo production has evolved rapidly in the horse over the past decade, but blastocyst rates from vitrified equine oocytes remain quite poor and further research is needed to warrant application.

Kompetensi Maturasi dan Fertilisasi Oosit Domba Prapubertas Secara In Vitro (DEVELOPMENTAL COMPETENCE OF MATURATION AND FERTILIZATION PREPUBERTAL SHEEP OOCYTES IN VITRO)

open access: yesJurnal Veteriner, 2017
The objective of this study was to evaluate the maturation and fertilization ability of oocytes frompre-pubertal sheep ovary in vitro. Prepubertal ovary were collected based on the absence of corpus luteum or absence of corpus albicans in both of the ...

Nonequilibrium dissipation in living oocytes [PDF]

open access: yesEPL 116, 30008 (2016), 2015
Living organisms are inherently out-of-equilibrium systems. We employ new developments in stochastic energetics and rely on a minimal microscopic model to predict the amount of mechanical energy dissipated by such dynamics. Our model includes complex rheological effects and nonequilibrium stochastic forces.

Comparing self‐reported race and genetic ancestry for identifying potential differentially methylated sites in endometrial cancer: insights from African ancestry proportions using machine learning models

open access: yesMolecular Oncology, EarlyView.
Integrating ancestry, differential methylation analysis, and machine learning, we identified robust epigenetic signature genes (ESGs) and Core‐ESGs in Black and White women with endometrial cancer. Core‐ESGs (namely APOBEC1 and PLEKHG5) methylation levels were significantly associated with survival, with tumors from high African ancestry (THA) showing ...
