The long term goal of the Nuclear Receptor Signaling Atlas (NURSA) resides in unraveling the physiological and pathological functions of nuclear receptors (NRs) at the molecular, biochemical and cellular levels. This multi-oriented task requires complementary approaches in order to determine the specific function(s) and precise expression and receptor activity patterns for each individual conve...
Transgenesis may allow the generation of farm animals with altered phenotype, animal models for research and animal bioreactors. Although such animals have been produced, the time and expense involved in generating transgenic livestock and then evaluating the transgene expression pattern is very restrictive. If questions about the ability and efficiency of expression could be asked solely in vi...
Transgenesis in cattle has provided numerous opportunities for livestock production. The development of nuclear transfer (NT) technology has improved the production of transgenic livestock. However, the isolation of pure colonies from a single transfection event remains laborious and can be a constraint in the production of transgenic livestock. We used 96-well cell culture plates to isolate ce...
Nuclear transfer procedures have been recently applied for clinical and research targets as a novel assisted reproductive technique and were used for increasing the oocyte activity during its growth and maturation. In this review, we summarized the nuclear transfer technique for germinal vesicle stage oocytes to reconstruct the maturation of them. Our study covered publications between 1966 and...
Somatic cell nuclear transfer and transcription factor mediated reprogramming are two widely used techniques for somatic cell reprogramming. Both fully reprogrammed nuclear transfer embryonic stem cells and induced pluripotent stem cells hold potential for regenerative medicine, and evaluation of the stem cell pluripotency state is crucial for these applications. Previous reports have shown tha...
Sperm nuclear transfer or intracytoplasmic sperm injection (ICSI) is a powerful assisted reproductive technology (ART) for treating human male infertility. Controversial reports of increased birth defects have raised concerns about the ART's safety. The cause for birth defects, however, has remained elusive for analysis in human because of the sample size, male infertility genetics, physiologic...
The use of mitochondrial transfer as a clinic procedure is drawing closer to reality. Here we provide a detailed overview of mitochondrial transfer techniques - both established and recent - including pronuclear, spindle, ooplasmic and blastomere transfer. Reasons as to why some techniques are more suitable for the prevention of mitochondrial DNA disease than others, as well as the advantages a...
Gene transfer technologies in mammals are the focus of renewed interest owing to the recent emphasis on analyzing gene function in the postgenomic era. Three important developments in this area include transgenics, gene targeting and nuclear transfer or animal cloning. These technological innovations have enhanced our ability to analyze gene function at the level of the whole organism and have ...
The somatic cell nuclear transfer (SCNT) technique is the most popular method for producing genetically modified pigs, but its efficiency depends upon a number of factors. In the present study, we attempted to generate transgenically cloned Guangxi Bama mini-pigs--which possess great potential for modeling human diseases--through genetic modification of fibroblasts, followed by SCNT and embryo ...
