Co-operation between Polymerases and Nucleotide Synthetases in the RNA World. [PDF]
PLoS Computational Biology, 2016 It is believed that life passed through an RNA World stage in which replication was sustained by catalytic RNAs (ribozymes). The two most obvious types of ribozymes are a polymerase, which uses a neighbouring strand as a template to make a complementary ...

, 2020 In searching for life in extraterrestrial space, it is essential to act based on an unequivocal definition of life. In the twentieth century, life was defined as cells that self-replicate, metabolize, and are open for mutations, without which genetic ...

Metabolite-dependent regulation of gene expression in trypanosoma brucei [PDF]
, 2013 Mechanisms regulating gene expression in trypanosomatid protozoa differ significantly from those in other eukaryotes. Transcription of the genome appears to be more or less constitutive with the polyadenylation and trans-splicing of large polycistronic ...

Molecular Oncology, EarlyView.Integrating ancestry, differential methylation analysis, and machine learning, we identified robust epigenetic signature genes (ESGs) and Core‐ESGs in Black and White women with endometrial cancer. Core‐ESGs (namely APOBEC1 and PLEKHG5) methylation levels were significantly associated with survival, with tumors from high African ancestry (THA) showing ...

How Amino Acids and Peptides Shaped the RNA World
Life, 2015 The “RNA world” hypothesis is seen as one of the main contenders for a viable theory on the origin of life. Relatively small RNAs have catalytic power, RNA is everywhere in present-day life, the ribosome is seen as a ribozyme, and rRNA and tRNA are ...

Origins of Life, RNA world or alternative RNA world
Cell & Developmental Biology, 2012 Why and how our living-bodies, such as human beings, have originated from a barely non-life planet into the highly-intelligent life existing Earth, and have been interested and pursued by large population of readers and investigators. Based on evolution of Darwin’s arguments, some detailed evolutionary theories and steps have been renewed and discussed

Molecular Oncology, EarlyView.Loss of the frequently mutated chromatin remodeler ARID1A, a subunit of the SWI/SNF cBAF complex, results in less open chromatin, alternative splicing, and the failure to stop cells from progressing through the cell cycle after DNA damage in bladder (cancer) cells. Created in BioRender. Epigenetic regulators, such as the SWI/SNF complex, with important

Comparative analysis of RNA families reveals distinct repertoires for each domain of life.
PLoS Computational Biology, 2012 The RNA world hypothesis, that RNA genomes and catalysts preceded DNA genomes and genetically-encoded protein catalysts, has been central to models for the early evolution of life on Earth.
