Triple coding in human SRD5A1 mRNA.

Background: Nucleotide sequence can be translated in three reading frames from 5' to 3' producing distinct protein products. Many examples of RNA translation in two reading frames (dual coding) have been identified so far.

Results: We report simultaneous translation of mRNA transcripts derived from locus in all three reading frames that result in the synthesis of long proteins.

Knockout Mice Exhibit Fraser Syndrome Phenotypes and Neonatal Lethality Due to Bilateral Renal Agenesis.

Fraser syndrome is a rare autosomal recessive disorder characterized by multiple congenital malformations, including cryptophthalmos, syndactyly, and renal agenesis, which can lead to severe complications beginning at the embryonic stage. Mutations in genes encoding extracellular matrix proteins such as FRAS1, FREM1, FREM2, and the associated trafficking protein GRIP1, are implicated in Fraser syndrome. These proteins are critical for maintaining epithelial integrity during embryogenesis, with deficiencies leading to tissue detachment and blistering phenotypes in mouse models.

RiboSeq.Org: an integrated suite of resources for ribosome profiling data analysis and visualization.

Ribosome profiling (Ribo-Seq) has revolutionised our understanding of translation, but the increasing complexity and volume of Ribo-Seq data present challenges for its reuse. Here, we formally introduce RiboSeq.Org, an integrated suite of resources designed to facilitate Ribo-Seq data analysis and visualisation within a web browser.

Translation Complex Profile Sequencing Allows Discrimination of Leaky Scanning and Reinitiation in Upstream Open Reading Frame-controlled Translation.

Upstream open reading frames (uORFs) are a class of translated regions (translons) in mRNA 5' leaders. uORFs are believed to be pervasive regulators of the translation of mammalian mRNAs. Some uORFs are highly repressive but others have little or no impact on downstream mRNA translation either due to inefficient recognition of their start codon(s) or/and due to efficient reinitiation after uORF translation.

Unraveling the developmental heterogeneity within the human retina to reconstruct the continuity of retinal ganglion cell maturation and stage-specific intrinsic and extrinsic factors.

Tissue development is a complex spatiotemporal process with multiple interdependent components. Anatomical, histological, sequencing, and evolutional strategies can be used to profile and explain tissue development from different perspectives. The introduction of scRNAseq methods and the computational tools allows to deconvolute developmental heterogeneity and draw a decomposed uniform map.
