Research group: Functional Genomics and Biotechnology of ncRNAs

The development of massive sequencing techniques of nucleic acids has allowed to discover new forms and routes of regulation of the gene expression in living beings. All this information points to an enormous complexity in the biology of multicellular eukaryotes, which makes us rethink the classical concept of gene, as well as the possible function of each pair of bases of a given genome. Within this revolution, it can be highlighted the central role of the RNA macromolecule in a multitude of biological processes, beyond the classical intermediary of genetic information. Our group is interested into finding and characterizing new biological functions for non-coding RNAs, focusing especially on their catalytic (ribozymes) and regulatory (riboswitches) capabilities, as well as on providing biotechnological utility to any of new RNA motif that we may discover. For all this, in the laboratory we use multidisciplinary approaches that combine Bioinformatics, Biochemistry and Molecular and Structural Biology, and mostly using plants as an experimental biological reference system.

 

Current lines of research: 

• To understand the biological roles and functions of circular RNAs with ribozymes encoded in plant and animal genomes (Cervera et al, Genome Biol 2016, De la Peña, Cevera, RNA Biol 2017).

• Bioinformatic search and characterization of new catalytic and regulatory RNA motifs (De la Peña et al., Molecules 2017).

• Functional characterization of small ribozymes associated with retrotransposons (Cervera, de la Peña, Mol Biol Evol 2014).

• To decipher the role of the small ribozymes in the human genome conserved in introns of antioncogenes and tumor antigens (De la Peña, García-Robles, EMBO Rep 2010, De la Peña et al., Biol Chem 2012).

• The development of biotechnological tools based on circular RNAs with ribozymes for gene therapies (De la Peña, Adv Exp Medicine Biology 2018).
