Loss of LINE-1 Activity in the Megabats [PDF]

Genetics, 2008
Abstract LINE-1 (L1) retrotransposons are the most abundant type of mammalian retroelement. They have profound effects on genome plasticity and have been proposed to fulfill essential host functions, yet it remains unclear where they lie on the spectrum from parasitism to mutualism.

BST2 Suppresses LINE-1 Retrotransposition by Reducing the Promoter Activity of LINE-1 5′ UTR

Journal of Virology, 2022
BST2 is a potent antiviral protein that suppresses the release of several enveloped viruses, mainly by tethering the envelope of newly synthesized virions and restraining them on the surface of producer cells. In mammalian cells, there are numerous DNA elements replicating through reverse transcription, among which LINE-1 is the only retroelement that ...

Improvement of slope soil consolidation capacity of plant root system based on regulation of root architecture

Rock and Soil Mechanics, 2021
The effect of plant slope protection is strongly associated with the root architecture in soil. In this paper, the water?fertilizer combination method was used to regulate the plant root configuration, and the influence of the regulated plant root ...

Well Killing Technology before Workover Operation in Complicated Conditions

Energies, 2021
Well killing is an important technological stage before conducting workover operation, one of the tasks of which is to preserve and restore the natural filtration characteristics of the bottomhole formation zone (BFZ). Special attention should be paid to

Organic Matter Structural Composition of Vascular Epiphytic Suspended Soils of South Vietnam

Applied Sciences, 2023
The biosphere organic matter is stored in nature in various forms. Most of it is associated with classical terrestrial organo-mineral soils. The carbon of woody plant biomass is counted separately from soil as carbon of the standing biomass. Nevertheless,

Characterization of LINE-1 Ribonucleoprotein Particles

PLoS Genetics, 2010
The average human genome contains a small cohort of active L1 retrotransposons that encode two proteins (ORF1p and ORF2p) required for their mobility (i.e., retrotransposition). Prior studies demonstrated that human ORF1p, L1 RNA, and an ORF2p-encoded reverse transcriptase activity are present in ribonucleoprotein (RNP) complexes.

LINE-1 Evasion of Epigenetic Repression in Humans [PDF]

Molecular Cell, 2019
Epigenetic silencing defends against LINE-1 (L1) retrotransposition in mammalian cells. However, the mechanisms that repress young L1 families and how L1 escapes to cause somatic genome mosaicism in the brain remain unclear. Here we report that a conserved Yin Yang 1 (YY1) transcription factor binding site mediates L1 promoter DNA methylation in ...

LSD: a Line Segment Detector [PDF]

, 2012
LSD is a linear-time Line Segment Detector giving subpixel accurate results. It is designed to work on any digital image without parameter tuning. It controls its own number of false detections: On average, one false alarms is allowed per image.
