Ribosomal DNA localization on Lathyrus species chromosomes by FISH
Journal of Genetic Engineering and Biotechnology, 2020 Background Fluorescence In Situ Hybridization (FISH) played an essential role to locate the ribosomal RNA genes on the chromosomes that offered a new tool to study the chromosome structure and evolution in plant. The 45S and 5S rRNA genes are independent

Leveraging Transcriptional Signatures of Diverse Stressors for Bumble Bee Conservation
Molecular Ecology, Volume 34, Issue 3, February 2025.ABSTRACT Organisms in nature are subjected to a variety of stressors, often simultaneously. Foremost among stressors of key pollinators are pathogens, poor nutrition and climate change. Landscape transcriptomics can be used to decipher the relative role of stressors, provided there are unique signatures of stress that can be reliably detected in field ...

Fluctuations in protein synthesis from a single RNA template: stochastic kinetics of ribosomes [PDF]
, 2008 Proteins are polymerized by cyclic machines called ribosome which use their messenger RNA (mRNA) track also as the corresponding template and the process is called translation. We explore, in depth and detail, the stochastic nature of the translation.

Keep calm and reboot – how cells restart transcription after DNA damage and DNA repair
FEBS Letters, Volume 599, Issue 2, Page 275-294, January 2025.DNA damage not only inhibits transcription but also disrupts nucleolar architecture. Upon DNA repair, it is crucial to restore RNA polymerase 1 and 2 transcription as well as nucleolar structure for cell survival. However, the mechanisms for reinstating them are complex and involve various proteins and processes that are still not fully understood ...

Ribosome self-assembly leads to overlapping reproduction cycles and increases growth rate [PDF]
arXiv, 2018 In permissive environments, E. coli can double its dry mass every 21 minutes. During this time, ribosomes, RNA polymerases, and the proteome are all doubled. Yet, the question of how to relate bacterial doubling time to other biologically relevant time scales in the growth process remains illusive, due to the complex temporal nesting pattern of these ...

ACR Open Rheumatology, Volume 7, Issue 1, January 2025.Objective Osteoarthritis (OA) is the most common cause of chronic disability in joints among older individuals. The primary goal of OA treatment is pain relief to improve the quality of life. Inflammation and aging are involved in the pathogenesis of pain in OA. In this study, we evaluated the ability of metformin to regulate microRNAs, such as miR‐451

arXiv, 2012 The simplest possible beginning of abiogenesis has been a riddle from the last century, which is most successfully solved by the Lipid World hypothesis. However, origin of the next stages of evolution starting form lipids is still in dark. We propose a 'Lipid-RNA World Scenario' based on the assumption that modern stable lipid-RNA interactions are ...

Resurrection of an ancestral 5S rRNA
BMC Evolutionary Biology, 2011 Background In addition to providing phylogenetic relationships, tree making procedures such as parsimony and maximum likelihood can make specific predictions of actual historical sequences.

TRE5-A retrotransposition profiling reveals putative RNA polymerase III transcription complex binding sites on the Dictyostelium extrachromosomal rDNA element. [PDF]
PLoS ONE, 2017 The amoeba Dictyostelium discoideum has a haploid genome in which two thirds of the DNA encodes proteins. Consequently, the space available for selfish mobile elements to expand without excess damage to the host genome is limited.
