Modeling early germline immunization after horizontal transfer of transposable elements reveals internal piRNA cluster heterogeneity

BMC Biology, 2023
Background A fraction of all genomes is composed of transposable elements (TEs) whose mobility needs to be carefully controlled. In gonads, TE activity is repressed by PIWI-interacting RNAs (piRNAs), a class of small RNAs synthesized by heterochromatic ...

Mechanistic insights into non-coding Y RNA processing

RNA Biology, 2022
Y RNAs (84–112 nt) are non-coding RNAs transcribed by RNA polymerase III and are characterized by a distinctive secondary structure. Human Y RNAs interact with the autoimmune proteins SSB and RO60 that together form a ribonucleoprotein (RNP) complex ...

The roles of small RNAs: insights from bacterial quorum sensing [PDF]

ExRNA, 2019
Ribonucleic acids (RNAs) mainly played auxiliary roles in regulations of genetic processes while recent explorations into small non-coding RNAs (sRNAs) in bacteria have broadened the scope of RNAs studies in these processes.

vtRNA2-1/nc886 Produces a Small RNA That Contributes to Its Tumor Suppression Action through the microRNA Pathway in Prostate Cancer

Non-Coding RNA, 2020
vtRNA2-1 is a vault RNA initially classified as microRNA precursor hsa-mir-886 and recently proposed as “nc886”, a new type of non-coding RNA involved in cancer progression acting as an oncogene and tumor suppressor gene in different tissues.
