This study was conducted to investigate whether lysophosphatidic acid (LPA) could improve the development of porcine somatic cell nuclear transfer (SCNT) embryos. Porcine SCNT-derived embryos were cultured in chemically defined polyvinyl alcohol (PVA)-based zygote medium (PZM)-4 without or with LPA, and development, proliferation potential, apoptosis, expression levels pluripotent markers evalu...
Bidirectional action of the Igf2r imprint control element on upstream and downstream imprinted genes
Background and objective: Association of 6q loci, where IGF2R gene is located, with insulin resistance has been well established. In this study, relationship between 3'UTR and type 2 diabetes and insulin resistance indices in non diabetic subjects was investigated. Materials and Methods: 350 participants (175 diabetic type 2 patient and 175 non-diabetic individuals) were entered in this study. ...
The only documents allowed are your own printed copy of the course slides and your personal notes. The use of electronic devices (computers, phones) is prohibited. The questions are written in English. You can answer either in English or French. The different parts in this exam are independent and can be solved in any order. It will not be answered to any question during the exam. In case of am...
In mammals, genomic imprinting governed by DNA methyltransferase DNMT3A and its cofactor DNMT3L is essential for functional gametes. Oocyte-specific methylation imprints are established during oocyte growth concomitant with DNMT3A/DNMT3L expression, although the mechanisms of oocyte-specific imprinting are not fully understood. To determine whether the presence of DNMT3A/DNMT3L in oocytes is su...
Alterations of learning and memory in mice with deregulated neuron-specific nuclear factor κB (NF-κB) activity support the idea that plastic changes of synaptic contacts may depend at least in part on IκB kinase (IKK)/NF-κB-related synapse-to-nucleus signaling. There is, however, little information on the molecular requirements and mechanisms regulating this IKK/NF-κB-dependent synapse developm...
Chicken growth performance provides direct economic benefits to the poultry industry. However, the underlying genetic mechanisms are unclear. The objective of this study was to identify candidate genes associated with chicken growth and investigate their potential mechanisms. We used RNA-Seq to study the breast muscle transcriptome in high and low tails of Recessive White Rock (WRRh, WRRl) and ...
DNA methylation is a major epigenetic modification in the mammalian genome that regulates crucial aspects of gene function. Mammalian cloning by somatic cell nuclear transfer (SCNT) often results in gestational or neonatal failure with only a small proportion of manipulated embryos producing live births. Many of the embryos that survive to term later succumb to a variety of abnormalities that a...
Deregulated apoptosis of MCs (mesangial cells) is associated with a number of kidney diseases including end-stage diabetic nephropathy. Cell death by apoptosis is a tightly orchestrated event, whose mechanisms are not completely defined. In the present study we show that the uPA (urokinase-type plasminogen activator)/uPAR (uPA receptor) system can initiate both cell survival and pro-apoptotic s...
