The piRNA-pathway factor FKBP6 is essential for spermatogenesis butdispensable for control of meiotic LINE-1 expression in humans.
Wyrwoll M.J. et al.
Infertility affects around 7\% of the male population and can be due to severe spermatogenic failure (SPGF), resulting in no or very few sperm in the ejaculate. We initially identified a homozygous frameshift variant in FKBP6 in a man with extreme oligozoospermia. Subsequently, we screened a total of 2,699 men with ...

The seminal plasma microbiome of men with testicular germ cell tumours described by small RNA sequencing
Nina Mørup, Ailsa Maria Main, Niels Jørgensen, Gedske Daugaard, Anders Juul, Kristian Almstrup
Background: It has been estimated that microorganisms are involved in the pathogenesis of approximately 20% of all cancers. Testicular germ cell tumours (TGCTs) are the most common type of malignancy in young men and arise from the precursor cell, Germ Cell Neoplasia in Situ (GCNIS). The microbiome of seminal p...

Neutral sphingomyelinase 2 inhibition attenuates extracellular vesiclerelease and improves neurobehavioral deficits in murine HIV.
Zhu X. et al.
People living with HIV (PLH) have significantly higher rates of cognitive impairment (CI) and major depressive disorder (MDD) versus the general population. The enzyme neutral sphingomyelinase 2 (nSMase2) is involved in the biogenesis of ceramide and extracellular vesicles (EVs), both of which are dysregulated in PL...

A novel, essential trans-splicing protein connects the nematode SL1snRNP to the CBC-ARS2 complex.
Fasimoye Rotimi Yemi et al.
Spliced leader trans-splicing is essential for gene expression in many eukaryotes. To elucidate the molecular mechanism of this process, we characterise the molecules associated with the Caenorhabditis elegans major spliced leader snRNP (SL1 snRNP), which donates the spliced leader that replaces the 5' untranslated ...

Interspecies effectors of a transgenerational memory of bacterial infection in Caenorhabditis elegans .
Legüe Marcela et al.
The inheritance of memory is an adaptive trait. Microbes challenge the immunity of organisms and trigger behavioral adaptations that can be inherited, but how bacteria produce inheritance of a trait is unknown. We use and its bacteria to study the transgenerational RNA dynamics of interspecies crosstalk leading to a...

Diverse Monogenic Subforms of Human Spermatogenic Failure
Nagirnaja L. et al.
Non-obstructive azoospermia (NOA) is the most severe form of male infertility and typically incurable with current medicine. Due to the biological complexity of sperm production, defining the genetic basis of NOA has proven challenging, and to date, the most advanced classification of NOA subforms is based on simple...

Ultrasensitive Ribo-seq reveals translational landscapes duringmammalian oocyte-to-embryo transition and pre-implantation development.
Xiong Zhuqing et al.
In mammals, translational control plays critical roles during oocyte-to-embryo transition (OET) when transcription ceases. However, the underlying regulatory mechanisms remain challenging to study. Here, using low-input Ribo-seq (Ribo-lite), we investigated translational landscapes during OET using 30-150 mouse oocy...

Translation is a key determinant controlling the fate of cytoplasmic longnon-coding RNAs
Andjus Sara et al.
Despite predicted to lack coding potential, cytoplasmic long non-coding (lnc)RNAs can associate with ribosomes, resulting in some cases into the production of functional peptides. However, the biological and mechanistic relevance of this pervasive lncRNAs translation remains poorly studied. In yeast, cytoplasmic Xrn...

MGcount: a total RNA-seq quantification tool to address multi-mappingand multi-overlapping alignments ambiguity in non-coding transcripts
Hita Andrea, Brocart Gilles, Fernandez Ana, Rehmsmeier Marc, Alemany Anna, Schvartzman Sol
Background Total-RNA sequencing (total-RNA-seq) allows the simultaneous study of both the coding and the non-coding transcriptome. Yet, computational pipelines have traditionally focused on particular biotypes, making assumptions that are not fullfilled by total-RNA-seq datasets. Transcripts from distinct RNA biotyp...

Single cell quantification of ribosome occupancy in early mouse development

Genes with 5′ terminal oligopyrimidine tracts preferentially escapeglobal suppression of translation by the SARS-CoV-2 NSP1 protein
Shilpa, Rao and Ian, Hoskins and P., Daniela Garcia and Tori, Tonn andHakan, Ozadam and Elif, Sarinay Cenik and ProfileCan, Cenik
Viruses rely on the host translation machinery to synthesize their own proteins. Consequently, they have evolved varied mechanisms to co-opt host translation for their survival. SARS-CoV-2 relies on a non-structural protein, NSP1, for shutting down host translation. Despite this, it is currently unknown how viral pr...

Non-coding RNA has a proven ability to direct and regulate chromatin modifications by acting as scaffolds between DNA and histone-modifying complexes. However, it is unknown if ncRNA plays any role in DNA replication and epigenome maintenance, including histone eviction and re-instalment of histone-modifications aft...
