Ancient Origin of the U2 Small Nuclear RNA Gene-Targeting Non-LTR Retrotransposons Utopia
Most non-long terminal repeat (non-LTR) retrotransposons encoding a restriction-like endonuclease show target-specific integration into repetitive sequences such as ribosomal RNA genes and microsatellites. However, only a few target-specific lineages of non-LTR retrotransposons are distributed widely and no lineage is found across the eukaryotic kingdoms. Here we report the most widely distribu...
متن کاملWidespread horizontal transfer of retrotransposons.
In higher organisms such as vertebrates, it is generally believed that lateral transfer of genetic information does not readily occur, with the exception of retroviral infection. However, horizontal transfer (HT) of protein coding repetitive elements is the simplest way to explain the patchy distribution of BovB, a long interspersed element (LINE) about 3.2 kb long, that has been found in rumin...
متن کاملSilencing of retrotransposons in Dictyostelium by DNA methylation and RNAi
We have identified a DNA methyltransferase of the Dnmt2 family in Dictyostelium that was denominated DnmA. Expression of the dnmA gene is downregulated during the developmental cycle. Overall DNA methylation in Dictyostelium is approximately 0.2% of the cytosine residues, which indicates its restriction to a limited set of genomic loci. Bisulfite sequencing of specific sites revealed that DnmA ...
متن کاملTargeting Radiotherapy to Cancer by Gene Transfer
Targeted radionuclide therapy is an alternative method of radiation treatment which uses a tumor-seeking agent carrying a radioactive atom to deposits of tumor, wherever in the body they may be located. Recent experimental data signifies promise for the amalgamation of gene transfer with radionuclide targeting. This review encompasses aspects of the integration of gene manipulation and targeted...
متن کاملTargeting Cardiac Myocytes by Gene Transfer
among the earliest in the field, and more recently gene and cell therapies have demonstrated significant potential for the treatment of common cardiovascular problems such as refractory myocardial ischaemia and dysfunction. Accumulating preclinical studies are providing an increasingly sound scientific basis for cautious human evaluation of additional gene and cell therapy strategies. Furthermo...
