Post-mortem Interval and Its Relation with the RNA Degradation in the Dental Pulp in Submerged Teeth
Post-mortem interval is the time between death and the discovery of the body or human remains. Teeth are the most resistant structures of the human body, able to withstand extreme conditions such as high temperature, humidity, and post-mortem degradation.

Incoherent dual regulation by a SAM-II riboswitch controlling translation at a distance
In Sinorhizobium meliloti, the methionine biosynthesis genes metA and metZ are preceded by S-adenosyl-L-methionine (SAM) riboswitches of the SAM-II class. Upon SAM binding, structural changes in the metZ riboswitch were predicted to cause transcriptional

Novel endoribonucleases as central players in various pathways of eukaryotic RNA metabolism [PDF]
For a long time it has been assumed that the decay of RNA in eukaryotes is mainly carried out by exoribonucleases, which is in contrast to bacteria, where endoribonucleases are well documented to initiate RNA degradation.

VfoldCPX Server: Predicting RNA-RNA Complex Structure and Stability. [PDF]
RNA-RNA interactions are essential for genomic RNA dimerization, mRNA splicing, and many RNA-related gene expression and regulation processes. The prediction of the structure and folding stability of RNA-RNA complexes is a problem of significant ...

Characterizing RNA stability genome-wide through combined analysis of PRO-seq and RNA-seq data
Background The concentrations of distinct types of RNA in cells result from a dynamic equilibrium between RNA synthesis and decay. Despite the critical importance of RNA decay rates, current approaches for measuring them are generally labor-intensive ...

Stability of SARS-CoV-2 RNA in Nonsupplemented Saliva
The expense of saliva collection devices designed to stabilize severe acute respiratory syndrome coronavirus 2 RNA is prohibitive to mass testing. However, virus RNA in nonsupplemented saliva is stable for extended periods and at elevated temperatures ...

Repression of PUM1-mediated mRNA decay activates translesion synthesis after DNA damage
Biological roles of Pumilio1 (PUM1) in ubiquitous cells remain unclear. Here we identify 48 degrading target mRNAs by combined analysis of transcriptome-wide mRNA stabilities and the binding of mRNAs.

Maf1-mediated repression of RNA polymerase III transcription inhibits tRNA degradation via RTD pathway [PDF]
tRNA precursors, which are transcribed by RNA polymerase III, undergo end-maturation, splicing and base modifications. Hypomodified tRNAs, such as tRNAVal(AAC), lacking 7-methylguanosine and 5-methylcytidine modifications, are subject to degradation by a

Frozen section histopathology and preanalytical factors affecting nucleic acid integrity in biobanked fresh-frozen human cancer tissues [PDF]
Background In this study, we evaluated the effects of storage duration and ischemic time on nucleic acid quality of fresh-frozen tissue (FFT) from colon adenocarcinoma (COAD), hepatocellular carcinoma (HCC), and renal cell carcinoma (RCC) collected at ...
