Retrotransposon hypomethylation in melanoma and expression of a placenta-specific gene.
PLoS ONE, 2014 In the human placenta, DNA hypomethylation permits the expression of retrotransposon-derived genes that are normally silenced by methylation in somatic tissues.

R-loop landscape in mature human sperm: Regulatory and evolutionary implications
Frontiers in Genetics, 2023 R-loops are three-stranded nucleic acid structures consisting of an RNA:DNA hybrid and a displaced DNA strand. While R-loops pose a potential threat to genome integrity, they constitute 5% of the human genome.

Short-term mutagenicity test by using IRAP molecular marker in rice grown under herbicide treatment
Biotechnology & Biotechnological Equipment, 2018 Rice is an economically important plant as well as a model organism. The rice genome consists of 35% retrotransposons. Although most of the retrotransposons are inactivated through evolutionary processes, they can be activated under various biotic and ...

A seed-specific regulator of triterpene saponin biosynthesis in Medicago truncatula [PDF]
, 2020 Plants produce a vast array of defense compounds to protect themselves from pathogen attack or herbivore predation. Saponins are a specific class of defense compounds comprising bioactive glycosides with a steroidal or triterpenoid aglycone backbone. The
