mRNA methylation is an important regulator of many physiological processes in eukaryotes but has not been studied in depth in prokaryotes. Working with bacterial mRNA is challenging because it lacks a poly(A)-tail. However, methods for detecting RNA modifications, both sequencing and mass spectrometry, rely on efficient preparation of mRNA. Here, we compared size-dependent separation by electrophoresis and rRNA depletion for enrichment of Escherichia coli mRNA. The purification success was monitored by qRT-PCR and RNA sequencing. Neither method allowed complete removal of rRNA. Nevertheless, we were able to quantitatively analyze several modified nucleosides in the different RNA types. We found evidence for stress dependent RNA modification reprofiling in rRNA, but also several modified nucleosides in the mRNA enriched fractions showed significant changes.

Hereditary transthyretin amyloidosis with polyneuropathy (ATTRv-PN) is a neurodegenerative disease caused by mutations in the gene encoding transthyretin (TTR). Despite amyloid deposition being pathognomonic for diagnosis, this pathology in nervous tissues cannot fully account for nerve degeneration, implying additional pathophysiology for neurodegeneration, which, however, has not yet been fully elucidated. In this study, neuroinflammation in ATTRv-PN was investigated by examining nerve morphometry, the blood-nerve barrier, and macrophage infiltration in the sural nerves of ATTRv-PN patients and the sciatic nerves of a complementary mouse system, i.

Objective: To study the subcutaneous adipose tissue (SAT) transcriptome in people with HIV (PWH) switching efavirenz (EFV) or a protease inhibitor (PI) to raltegravir and to compare the transcriptome of PWH to those of people without HIV (PWoH).
Design: PWH (n = 36) on EFV (n = 22) or a PI (n = 14) based ART regimen were randomized to switch to RAL (n = 15) or to continue unchanged medication (n = 17). PWoH (n = 10), comparable in age and body mass index, were included for comparison.

Mesenchymal stem cells (MSCs) are pluripotent stem cells with self-renewal. They play a critical role in cell therapy due to their powerful immunomodulatory and regenerative effects. Recent studies suggest that one of the key therapeutic mechanisms of MSCs seems to derive from their paracrine product, called extracellular vesicles (EVs).

Background: Hepatocellular carcinoma (HCC), the most common form of liver cancer, has a significant mortality rate, largely due to late diagnosis. Recent advances in medical research have demonstrated the potential of biomarkers for early detection. Moreover, the discovery and use of prognostic biomarkers offer a ray of hope in the fight against liver cancer.
