Autophagy in cancer and protein conformational disorders
FEBS Letters, EarlyView.Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Generalized RNA-Directed Recombination of RNA [PDF]
Chemistry & Biology, 2003 RNA strand exchange through phosphor-nucleotidyl transfer reactions is an intrinsic chemistry promoted by group I intron ribozymes. We show here that Tetrahymena and Azoarcus ribozymes can promote RNA oligonucleotide recombination in either two-pot or one-pot schemes. These ribozymes bind one oligonucleotide, cleave following a guide sequence, transfer

Computational identification and analysis of noncoding RNAs - Unearthing the buried treasures in the genome [PDF]
, 2007 The central dogma of molecular biology states that the genetic information flows from DNA to RNA to protein. This dogma has exerted a substantial influence on our understanding of the genetic activities in the cells.

Non-coding RNAs participate in the regulatory network of CLDN4 via ceRNA mediated miRNA evasion [PDF]
, 2017 Thousands of genes have been well demonstrated to play important roles in cancer progression. As genes do not function in isolation, they can be grouped into “networks” based on their interactions.

microRNA Therapeutics in Cancer — An Emerging Concept
EBioMedicine, 2016 MicroRNAs (miRNAs) are an evolutionarily conserved class of small, regulatory non-coding RNAs that negatively regulate protein coding gene and other non-coding transcripts expression.

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

RNA Captor: A Tool for RNA Characterization
PLoS ONE, 2011 In the genome era, characterizing the structure and the function of RNA molecules remains a major challenge. Alternative transcripts and non-protein-coding genes are poorly recognized by the current genome-annotation algorithms and efficient tools are needed to isolate the less-abundant or stable RNAs.A universal RNA-tagging method using the T4 RNA ...

FEBS Letters, EarlyView.Glutaredoxin (Grx) 3 proteins contain a thioredoxin domain and one to three class II Grx domains. These proteins play a crucial role in iron homeostasis in eukaryotic cells. In human Grx3, at least one of the two Grx domains, together with the thioredoxin domain, is essential for its function in iron metabolism.

RNA-directed DNA methylation involves co-transcriptional small-RNA-guided slicing of polymerase V transcripts in Arabidopsis. [PDF]
, 2018 Small RNAs regulate chromatin modifications such as DNA methylation and gene silencing across eukaryotic genomes. In plants, RNA-directed DNA methylation (RdDM) requires 24-nucleotide small interfering RNAs (siRNAs) that bind to ARGONAUTE 4 (AGO4) and ...

Can we always sweep the details of RNA-processing under the carpet? [PDF]
, 2013 RNA molecules follow a succession of enzyme-mediated processing steps from transcription until maturation. The participating enzymes, for example the spliceosome for mRNAs and Drosha and Dicer for microRNAs, are also produced in the cell and their copy-numbers fluctuate over time.
