Role of the Mitochondrial Genome During Early Development in Mice [PDF]

open access: yes, 1973
The role of the mitochondrial genome in early development and differentiation was studied in mouse embryos cultured in vitro from the two to four cell stage to the blastocyst (about 100 cells).

HIV‐1 establishes immediate latency in T cells expressing the viral Nef protein

open access: yesFEBS 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 ...

Effect of growth medium composition on the efficiency of non-ribosomal synthesis in bacteria of the genus Bacillus [PDF]

open access: yesBIO Web of Conferences
Bacteria of the genus Bacillus are known for their ability to suppress a wide range of pathogenic microflora through the production of a variety of secondary metabolites, a significant proportion of which are non-ribosomal peptides.

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

open access: yesFEBS 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.

Developmental, Neuroanatomical and Cellular Expression of Genes Causing Dystonia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Dystonia is one of the most common movement disorders, with variants in multiple genes identified as causative. However, an understanding of which developmental stages, brain regions, and cell types are most relevant is crucial for developing relevant disease models and therapeutics.

Nutrient availability dictates the regulation of metabolism by the ribosomal protein-MDM2-p53 pathway

open access: yesMolecular & Cellular Oncology, 2018
Nutrient availability alters ribosomal biogenesis, causing ribosomal proteins to act as secondary messengers of nutrient response by binding to MDM2 and activating p53. Recent work suggests that the ribosomal protein (RP)-MDM2-p53 pathway responds to the

Spatial Analysis of Arabidopsis thaliana Gene Expression in Response to Turnip mosaic virus Infection

open access: yesMolecular Plant-Microbe Interactions, 2007
Virus-infected leaf tissues comprise a heterogeneous mixture of cells at different stages of infection. The spatial and temporal relationships between sites of virus accumulation and the accompanying host responses, such as altered host gene expression ...

Unraveling the Molecular Mechanisms of Glioma Recurrence: A Study Integrating Single‐Cell and Spatial Transcriptomics

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Glioma recurrence severely impacts patient prognosis, with current treatments showing limited efficacy. Traditional methods struggle to analyze recurrence mechanisms due to challenges in assessing tumor heterogeneity, spatial dynamics, and gene networks.

Anti-ribosomal P2: could it be a useful new criterion for patients with systemic lupus erythematosus?

open access: yesEgyptian Rheumatology and Rehabilitation
Background Systemic lupus erythematosus is a multisystem autoimmune disorder that displays numerous autoantibodies such as anti-nuclear, anti-Smith, anti-double-stranded DNA, and anti-ribosomal antibodies.

Conformational switches control early maturation of the eukaryotic small ribosomal subunit

open access: yeseLife, 2019
Eukaryotic ribosome biogenesis is initiated with the transcription of pre-ribosomal RNA at the 5’ external transcribed spacer, which directs the early association of assembly factors but is absent from the mature ribosome.
