Histone variant H3.5 in testicular cell differentiation and its interactions with histone chaperones.

Testicular cell differentiation is a highly regulated process, essential for male reproductive health. The histone variant H3.5 is apparently a critical player in this intricate orchestra of cell types, but its regulation and function remains poorly understood.

Exploring Individual and Contextual Factors Associated With Sexual Risk and Substance Use Among Underserved GBQMSM and Transgender and Nonbinary Persons in South Central Appalachia.

Gay, bisexual, queer, and other men who have sex with men (GBQMSM) and transgender and nonbinary persons are at elevated risk for HIV, sexually transmitted infections (STIs), and hepatitis C (HCV); in Appalachia, these communities experience more disease burden. However, little is known about the factors influencing risk. Sixteen semistructured in-depth interviews were conducted examining factors influencing prevention and care.

Uncovering the gastrointestinal passage, intestinal epithelial cellular uptake, and AGO2 loading of milk miRNAs in neonates using xenomiRs as tracers.

Background: Human breast milk has a high microRNA (miRNA) content. It remains unknown whether and how milk miRNAs might affect intestinal gene regulation and homeostasis of the developing microbiome after initiating enteral nutrition. However, this requires that relevant milk miRNA amounts survive the gastrointestinal (GI) passage, are taken up by cells, and become available to the RNA interference machinery.

The Overlooked Microbiome-Considering Archaea and Eukaryotes Using Multiplex Nanopore-16S-/18S-rDNA-Sequencing: A Technical Report Focusing on Nasopharyngeal Microbiomes.

In contrast to bacteria, microbiome analyses often neglect archaea, but also eukaryotes. This is partly because they are difficult to culture due to their demanding growth requirements, or some even have to be classified as uncultured microorganisms. Consequently, little is known about the relevance of archaea in human health and diseases.

An Adenoviral Vector as a Versatile Tool for Delivery and Expression of miRNAs.

Only two decades after discovering miRNAs, our understanding of the functional effects of deregulated miRNAs in the development of diseases, particularly cancer, has been rapidly evolving. These observations and functional studies provide the basis for developing miRNA-based diagnostic markers or new therapeutic strategies. Adenoviral (Ad) vectors belong to the most frequently used vector types in gene therapy and are suitable for strong short-term transgene expression in a variety of cells.
