Preface
More than 60 years ago, in 1954, James Watson and the Russian Physicist George
Gamow founded the “RNA Tie club”, a scientific club of selected gentlemen
members with the main objective of sharing their ideas and findings not yet mature
enough to be published in scientific journals. Brainstorming sessions gave rise to
many seminal concepts in cell biology, which were further demonstrated by labo-
ratoryexperiences.Gamow postulated the concept ofa “genetic code” based onthe
existence of triplets of bases (codons) that will translate the DNA language into
proteinaminoacids.Furthermore,inthelast1950s,anotherillustratedmemberofthe
club, Francis Crick, enunciated the “adaptor theory” based on an intermediate
molecule (transfer-RNA) that would be the physical link between nucleic acids and
proteins. These ideas were later described in an essential Crick’s article, which is
consideredbymanyauthorsastheembryoniccoreoftheconceptoftheRNAworld.
The RNA world stands on the idea that RNA molecules were the first precursors
ofthelivingcells,beingtheoriginoftheevolutionofallbiologicalmacromolecules.
Several arguments clearly support the theory that the primitive cells could be built
over processing units based on RNA molecules, including the existence of catalytic
RNA molecules. However, for long time the chemical and structural similarities
between DNA and RNA, catalogued RNA as a short-life accessory player in cell
physiology. Moreover, the paradigm of the reduced stability of RNA vs DNA
prevented for a long time the consideration of RNA as a precursor molecule. In
consequence, RNA must be placed at the root of the molecular tree of life.

organisms whose genomes are almost entirely composed of closely packed protein
coding sequences. However, this is not the case in higher organisms in which pro-
teomes and their coding sequences occupy only a tiny fraction of the genome.

humans and other complex organisms suggests that a second tier of genetic output

which may enable the integration and coordination of sophisticated suites of gene
expression required for differentiation and development.
Recent evidences also pointed out to the pivotal role of ncRNAs in the
cell-to-cell communication phenomenon, suggesting a transversal role of ncRNA
molecules as modulators in organism interaction. There is a common and central
biological language represented by functional RNA molecules. Within a complex
multi-cellular organism, cells are able to secrete ncRNAs that can travel using the
circulating biofluids to reach distant targets where they will exert their regulatory
actions functioning as slow genetic hormones. In pathological conditions such as
cancer, experimental evidences suggested the use of ncRNAs by tumour cells to
preparetheirtissueniche before ametastatic colonization. Different organisms can

and fungi that can hijack the host defenses using ncRNAs, but also this phe-
nomenon can be observed in mutualistic and symbiotic interactions.
The present book is a compilation of selected biological topics where ncRNAs
are mediators of inter-kingdom communication. The book is divided in two main
sectionscoveringtheroleofncRNAsinbacterialandviralinteractionwithdifferent

organisms.

The Roles of MicroRNAs and PiRNAs
in Virus-Host Interactions
Anh T. Tran
Abstract MicroRNAs (miRNAs) and Piwi-interacting RNAs (piRNAs) are two
groups of small non-coding RNAs with different functional roles. miRNAs are
post-transcriptionalregulatorsofgeneexpressioninaplethoraofcriticalprocesses
in multicellular eukaryotes. Therefore, it comes as no surprise that viral pathogens
have evolved ways to subvert the miRNA network. It is increasingly evident that
miRNAs have functional roles in viral replication as well as their potential
employment by host cells to combat viral infection. A number of viruses are now
known to encode for miRNAs, predominantly in DNA viruses such as her-
pesviruses. Although virus-encoded miRNAs have been reported in retroviruses
such as HIV-1, their functional significance is under debate. This controversy also

genesforsomeoftheseviralmiRNAssuggeststheymayfunctionintheregulation
of lytic and latent viral replication and in restricting antiviral responses. Viruses
have also evolved the ability to downregulate or upregulate the expression of
specific cellular miRNAs to enhance their replication. I will also briefly review
evidencethatdemonstratetheroleofpiRNAsinsilencingtransposableelementsto
maintain germline genome integrity. This chapter provides an overview of our
current understanding of the complex relationship between viruses and cellular
miRNA and piRNA machineries.

1.1.1 miRNAs
miRNAs are noncoding RNAs *21–23 nucleotide (nt) in length that
post-transcriptionally regulate the expression of a plethora of eukaryotic genes.
