Long terminal repeat retrotransposons (LTR-RTs) represent a major fraction of plant genomes, but processes leading to transposition bursts remain elusive. Polyploidy expectedly leads to LTR-RT proliferation, as the merging of divergent diploids provokes a genome shock activating LTR-RTs and/or genetic redundancy supports the accumulation of active LTR-RTs through relaxation of selective constra...

Marek’s disease (MD), a lymphoproliferative disorder of chickens caused by the MD virus (MDV), is economically significant. The resistance/susceptibility to MD is controlled by host genetics. The host response to different virus strains varies. The pathogenicity of REV-LTR deleted GX0101∆LTR MDV has been previously reported. However, the precise molecular mechanism of the response of chickens t...

Horizontal transfer (HT) is a complex phenomenon usually used as an explanation of phylogenetic inconsistence, which cannot be interpreted in terms of vertical evolution. Most examples of HT of eukaryotic genes involve transposable elements. An intriguing feature of HT is that its frequency differs among transposable elements classes. Although HT is well known for DNA transposons and long termi...

In plants, the genome of the host responds to the amplification of transposable elements (TEs) with DNA methylation. However, neither the factors involved in TE methylation nor the dynamics of the host-TE interaction are well resolved. Here, we identify 5,522 long terminal repeat retrotransposons (LTR-RT) in the genome of Oryza sativa ssp. japonica and then assess methylation for individual ele...

Abstract In this article, we compare short‐term rental (STR) and long‐term (LTR) price patterns in London using one of the most popular STR platforms, Airbnb, LTR platform, Zoopla property website. This research aims to enhance our understanding both patterns; as well dynamics specifically, predictive modeling analyze how might evolve. We used coefficient variation correlation analysis examine ...

The size and scope of microarray experiments continue to increase. However, datasets generated on different platforms or at different centres contain biases. Improved techniques are needed to remove platform- and batch-specific biases. One experimental control is the replicate hybridization of a subset of samples at each site or on each platform to learn the relationship between the two platfor...

A chimeric gene, recombined in vitro, containing a long terminal repeat (LTR) sequence from the proviral DNA of mouse mammary tumor virus and the thymidine kinase (tk) gene of Herpes Simplex Virus was introduced into L tk- cells. No transcription of LTR RNA was observed in transfected cells when glucocorticoid hormones were absent from the growth medium. Accumulation of LTR initiated RNA was me...

In flowering plants, the accumulation of small deletions through unequal homologous recombination (UR) and illegitimate recombination (IR) is proposed to be the major process counteracting genome expansion, which is caused primarily by the periodic amplification of long terminal repeat retrotransposons (LTR-RTs). However, the full suite of evolutionary forces that govern the gain or loss of tra...

We previously reported that inflammatory arthropathy resembling rheumatoid arthritis (RA) develops among transgenic mice carrying the long terminal repeat (LTR)-env-pX-LTR region of human T cell leukemia virus type I (LTR-pX-Tg mice). Because four genes are encoded in this region, we produced transgenic mice that only express the tax gene to examine its role in the development of arthritis. Tra...

OBJECTIVE To test the hypothesis that a safety margin may affect local tumor recurrence (LTR) in subsegmental chemoembolization. MATERIALS AND METHODS In 101 patients with 128 hepatocellular carcinoma (HCC) nodules (1-3 cm in size and ≤ 3 in number), cone-beam CT-assisted subsegmental lipiodol chemoembolization was performed. Immediately thereafter, a non-contrast thin-section CT image was ob...
