Inhibition of c-Jun N-terminal kinase (JNK) suppresses porcine oocyte ageing in vitro
MAPK DNA fragmentation apoptosis Bax
2015/6/24
Oocyte ageing is a complex of processes that occur when matured in vitro oocytes are, after reaching the metaphase II stage, exposed to further in vitro culture. Aged oocytes remaining at the metaphas...
Effects of oocyte collection techniques and maturation media on in vitro maturation and subsequent embryo development in Boer goat
Boer goat collection techniques oocyte maturation ovary medium
2015/6/4
The oocytes (experiment 1) were harvested by one of the four collection techniques (slicing, puncture, aspiration I and aspiration II) and the total number and the number of each grade of oocytes were...
Characterizing the Heavy Metal Chelator, TPEN, as a Ca2+ Tool in the Mammalian Oocyte
Calcium Oocyte TPEN Endoplasmic Reticulum Egg
2014/12/12
N,N,N’,N’-tetrakis-(2-Pyridylmethyl) ethylenediamine (TPEN) is a heavy metal chelator with high affinity for zinc. TPEN causes important responses in mammalian eggs. For example, these eggs are arrest...
CHARACTERIZATION OF Ca2+ INFLUX PATHWAY(S) DURING MOUSE OOCYTE MATURATION
Calcium influx oocyte maturation SOCE Stim1 Phosphorylation
2014/12/10
Ca2+ signaling induced at fertilization, also known as oscillations, is essential in mammalian eggs to initiate early embryonic development. The generation of the oscillations relies on optimization o...
Siberian Sturgeon Oocyte Extract Induces Epigenetic Modifications of Porcine Somatic Cells and Improves Developmental Competence of SCNT Embryos
Epigenetic Modifications Somatic Cell Nuclear Transfer Siberian Sturgeon Oocyte Extract
2016/5/16
Somatic cell nuclear transfer (SCNT) has generally demonstrated that a differentiated cell can convert into a undifferentiated or pluripotent state. In the SCNT experiment, nuclear reprogramming is in...
Effects of Trichostatin A on Cumulus Expansion during Mouse Oocyte Maturation
Mouse Cumulus-oocyte Complex Cumulus Expansion TSA
2016/5/12
This study was conducted to investigate the effects of Trichostatin A (TSA) on cumulus expansion during mouse oocyte maturation. TSA treatment inhibited cumulus expansion and significantly reduced the...
Ovarian Follicular Dynamics, Ovarian Follicular Growth, Oocyte Yield, In vitro Embryo Production and Repeated Oocyte Pick Up in Thai Native Heifers Undergoing Superstimulation
FSH Follicle OPU COCs IVP Cattle
2016/5/11
The objective of this study was to compare the effectiveness of the protocols for superstimulation of follicular growth in Thai native heifers. Heifers (n = 20) were randomly divided into four groups ...
Comparison of Gene Expression between Cumulus Oocyte Complexes and Naked Oocytes by Suppression Subtractive Hybridization in Swine
Suppression Subtractive Hybridization (SSH) Gene Expression Cumulus Cells Porcine
2016/5/3
In the antral follicle phase, several layers of cumulus cells surround the oocyte and play an important support and regulation role in oocyte development and maturation via intercellular communication...
Regulatory Mechanism of Spindle Movements during Oocyte Meiotic Division
Spindle Movement Meiotic Division Cytoskeleton Oocyte
2016/5/3
Female germ cell meiotic divisions are typically asymmetric, giving rise to two daughter cells with different sizes. Spindle movements including spindle migration from the oocyte center to the cortex ...
An Antisense Oligodeoxynucleotide to the LH Receptor Attenuates FSH-induced Oocyte Maturation in Mice
Cumulus-enclosed Oocyte LH Receptor Oligodeoxynucleotide Mouse
2016/4/28
It has been recently shown that expression of the LH receptor (LHR) in cumulus cells is related with FSH-induced meiotic resumption of mouse cumulus enclosed oocytes (CEOs). However, to date, it is st...
