Friend or Foe: Epigenetic Regulation of Retrotransposons in Mammalian Oogenesis and Early Development
Epigenetics is the study of phenotypic variation arising from developmental and environmental factors regulating gene transcription at molecular, cellular, and physiological levels. A naturally occurring biological process driven by epigenetics is the egg-to-embryo developmental transition when two fully differentiated adult cells - egg and sperm - revert to an early stem cell type with totipot...
متن کاملManipulating mammalian genome by gene targeting.
The development of strategies which allow the inactivation of specific murine genes by homologous recombination in embryonic cells has revolutionized biological science in the last 10 years. A large number of mice carrying genetic lesions, generated by gene targeting technology, has tremendously increased our knowledge in many areas of biology, culminating in the identification of mouse models ...
متن کاملManipulating the mammalian genome by homologous recombination.
Gene targeting in mammalian cells has proven invaluable in biotechnology, in studies of gene structure and function, and in understanding chromosome dynamics. It also offers a potential tool for gene-therapeutic applications. Two limitations constrain the current technology: the low rate of homologous recombination in mammalian cells and the high rate of random (nontargeted) integration of the ...
متن کاملControl of mammalian retrotransposons by cellular RNA processing activities
Retrotransposons make up roughly 50% of the mammalian genome and have played an important role in genome evolution. A small fraction of non-LTR retrotransposons, LINE-1 and SINE elements, is currently active in the human genome. These elements move in our genome using an intermediate RNA and a reverse transcriptase activity by a copy and paste mechanism. Their ongoing mobilization can impact th...
متن کاملLoss of ATRX in Chondrocytes Has Minimal Effects on Skeletal Development
BACKGROUND Mutations in the human ATRX gene cause developmental defects, including skeletal deformities and dwarfism. ATRX encodes a chromatin remodeling protein, however the role of ATRX in skeletal development is currently unknown. METHODOLOGY/PRINCIPAL FINDINGS We induced Atrx deletion in mouse cartilage using the Cre-loxP system, with Cre expression driven by the collagen II (Col2a1) prom...
