متن کاملTrash or Treasure: extracellular microRNAs and cell-to-cell communication
Circulating RNAs in human body fluids are promising candidates for diagnostic purposes. However, the biological significance of circulating RNAs remains elusive. Recently, small non-coding RNAs, microRNAs (miRNAs), were isolated from multiple human body fluids, and these "circulating miRNAs" have been implicated as novel disease biomarkers. Concurrently, miRNAs were also identified in the extra...
متن کاملChromosome Pairing: A Hidden Treasure No More

One organizational state that chromosomes adopt is pairing in a homology-dependent manner [3–8]. Although homolog pairing in meiosis has been extensively studied and is important for chromosome segregation, pairing of hom...
