Long interspersed nuclear element - Wikipedia
LINEs are the most abundant transposable element within the human genome, [8] with approximately 20.7% of the sequences identified as being derived from LINEs. The only active lineage of LINE found within humans belongs to the LINE-1 class, and is referred to as L1Hs. [9]
LINE1 - Wikipedia
LINE1 (an abbreviation of Long interspersed nuclear element-1, also known as L1 and LINE-1) is a family of related class I transposable elements in the DNA of many groups of eukaryotes, including animals and plants, classified with the long interspersed nuclear elements (LINEs). [1]
Long Interspersed Nuclear Element - an overview - ScienceDirect
Long Interspersed Nuclear Element-1 (LINE-1) are DNAs that compromise 17% of our genome. LINE-1 expression is triggered by environmental stressors and accomplished through its demethylation leading to genomic instability.
Long (LINEs) and the Short (SINEs) of It: Altered Methylation as a ...
2003年10月1日 · The mutagenicity and/or altered genome stability resulting from expression and movement of transposable elements, in particular, LINEs and SINEs, may occur subsequent to epigenetic changes, e.g., altered DNA methylation.
Short interspersed nuclear element - Wikipedia
Short interspersed nuclear elements (SINEs) are non-autonomous, non-coding transposable elements (TEs) that are about 100 to 700 base pairs in length. [1] They are a class of retrotransposons, DNA elements that amplify themselves throughout eukaryotic genomes, often through RNA intermediates. SINEs compose about 13% of the mammalian genome.

2024年7月4日 · The impact of transposable elements (TEs) on gene regulatory networks and how they are governed remain poorly understood. A new study identifies a role for LINE1, a specific subset of TEs, in the...
The Human LINE-1 Retrotransposon Creates DNA Double-strand …
2006年4月14日 · Long interspersed element-1 (L1) is an autonomous retroelement that is active in the human genome. The proposed mechanism of insertion for L1 suggests that cleavage of both strands of genomic DNA is required. We demonstrate that L1 expression leads to a high level of double-strand break (DSB) formation in DNA using immunolocalization of γ-H2AX ...
