Long-term inheritance of the 28S rDNA-specific retrotransposon R2.
R2 is a non-long-terminal-repeat (LTR) retrotransposon that inserts specifically into 28S rDNA. R2 has been identified in many species of arthropods and three species of chordates. R2 may be even more widely distributed in animals, and its origin may be traceable to early animal evolution. In this study, we identified R2 elements in medaka fish, White Cloud Mountain minnow, Reeves' turtle, hagf...
متن کاملExpression of Endoderm and Hepatic Specific Genes after in vitro Differentiation of Human Embryonic Stem Cells
Background: Human embryonic stem cells (hESC), which are derived from the inner cell mass of the blastocysts, have been considered to be pluripotent cells. In this study we examine the differentiating potential of hESC into hepatocytes by characterization of the expression of endoderm and liver-specific genes. Methods: hESC were cultivated in suspension to form aggregates, the embryoid bodies. ...
متن کاملTissue Specific Expression of Human Calcitonin Gene in Potato Tubers by an Organ Specific Promoter
To increase the production level of heterologous proteins in plants, strategies such as choice of strongerpromoters, optimization of codon usage and specific localization of foreign proteins are of major concern.Calcitonin (CT), a 32 amino acid polypeptide is a powerful and specific inhibitor of bone resorption and isused to treat several human diseases. Calcitonin activity is...
متن کاملLINE-1 retrotransposition in human embryonic stem cells.
LINE-1 elements comprise approximately 17% of human DNA and their mobility continues to impact genome evolution. However, little is known about the types of non-transformed cells that can support LINE-1 retrotransposition. Here, we show that human embryonic stem cells express endogenous LINE-1 elements and can accommodate LINE-1 retrotransposition in vitro. The resultant retrotransposition even...
متن کاملLINE-1 Retrotransposition Activity in Human Genomes
Highly active (i.e., "hot") long interspersed element-1 (LINE-1 or L1) sequences comprise the bulk of retrotransposition activity in the human genome; however, the abundance of hot L1s in the human population remains largely unexplored. Here, we used a fosmid-based, paired-end DNA sequencing strategy to identify 68 full-length L1s that are differentially present among individuals but are absent...
