FEBS Open Bio, EarlyView.ZFAS1 is a lncRNA promoting cell proliferation and migration, exhibiting high expression in various cancers. It is conserved, widely expressed, and produces multiple splice variants with unclear roles. We identified several splice variants in hepatocyte models, and found that inhibiting or suppressing regulators of the unfolded protein response (PERK ...

Molecular characterization and biodiversity of wood-decaying fungi in French Guiana [PDF]
, 2014 Fungi from tropical regions are currently under-represented in the classification system. Indeed, difficult access to tropical forests and irregular occurrence carpophores make it complicated to study fungus species in such environments, unlike in ...

HIV‐1 establishes immediate latency in T cells expressing the viral Nef protein
FEBS Open Bio, EarlyView.Nef is a viral protein often omitted from HIV‐1 reporter viruses. Consequently, its role in viral latency is unclear. We developed three novel dual reporter HIV‐1 derivatives that express Nef and allow for detection of latent and productive infection. Using these reporters, we show that Nef does not affect the establishment of immediate viral latency ...

ABH2 Couples Regulation of Ribosomal DNA Transcription with DNA Alkylation Repair
Cell Reports, 2013 Transcription has been linked to DNA damage. How the most highly transcribed mammalian ribosomal (rDNA) genes maintain genome integrity in the absence of transcription-coupled DNA damage repair is poorly understood.

The Amplified Ribosomal DNA of Dytiscid Beetles [PDF]
Proceedings of the National Academy of Sciences, 1974 During oogenesis in many animals there is a massive extrachromosomal synthesis of the genes for ribosomal RNA. In Dytiscid beetles, as in the toad Xenopus , the amplified ribosomal DNA occurs as circular molecules of different sizes. The circles fall into size classes that are integral multiples of a unit circle. It

Mycosphaerella podagrariae - a necrotrophic phytopathogen forming a special cellular interaction with its host Aegopodium podagraria [PDF]
, 2010 We present a new kind of cellular interaction found between Mycosphaerella podagrariae and Aegopodium podagraria, which is remarkably different to the interaction type of the obligate biotrophic fungus Cymadothea trifolii, another member of the ...

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control
FEBS Open Bio, EarlyView.Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

Balancing copy number in ribosomal DNA [PDF]
Proceedings of the National Academy of Sciences, 2015 Ecologists recognize the balance of nature as a complex system that arises from interacting and connected parts; disturbing the balance can affect other species in nonlinear and dynamic ways. Like ecosystems, the cell and genome are extensively connected by an abundance of molecular interactions. Upsetting the molecular balance, through changes in gene
