Next-generation RNA sequence analysis of platelets from an individual with autosomal recessive gray platelet syndrome detected abnormal transcript reads, including intron retention, mapping to NBEAL2 (encoding neurobeachin-like 2), which was confirmed as the genetic cause of GPS.
Abstract
Next-generation RNA sequence analysis of platelets from an individual with autosomal recessive gray platelet syndrome (GPS, MIM139090) detected abnormal transcript reads, including intron retention, mapping to NBEAL2 (encoding neurobeachin-like 2). Genomic DNA sequencing confirmed mutations in NBEAL2 as the genetic cause of GPS. NBEAL2 encodes a protein containing a BEACH domain that is predicted to be involved in vesicular trafficking and may be critical for the development of platelet α-granules.

Platelet secretion: From haemostasis to wound healing and beyond

TL;DR: Current understanding of the roles of platelet secretion in health and disease is summarized, and some of the hypotheses that may explain how platelets may control the release of its many secreted components in a context-specific manner are discussed to allow platelets to play multiple roles in health.

The complex transcriptional landscape of the anucleate human platelet

TL;DR: Deep-sequence RNA from leukocyte-depleted platelets is deep-sequenced to capture the complex profile of all expressed transcripts, revealing diverse classes of non-coding RNAs, including: pervasive antisense transcripts to protein-c coding loci; numerous, previously unreported and abundant microRNAs; retrotransposons; and thousands of novel un-annotated long and short intronic transcripts, an intriguing finding considering the anucleate nature of platelets.

Platelets and cancer: a casual or causal relationship: revisited.

TL;DR: Human platelets arise as subcellular fragments of megakaryocytes in bone marrow and are essential to hemostasis, vascular integrity, angiogenesis, inflammation, innate immunity, wound healing, and cancer biology.

Lysosome-related organelles: unusual compartments become mainstream.

TL;DR: New insights have revealed previously unappreciated specialized endosomal sorting processes in all cell types, and are expanding the views of the plasticity of the endosome and secretory systems in adapting to cell type-specific needs.

Membrane recognition by phospholipid-binding domains.

TL;DR: Many different globular domains bind to the surfaces of cellular membranes, or to specific phospholipid components in these membranes, and this binding is often tightly regulated.

The WD repeat: a common architecture for diverse functions.

TL;DR: The solution of the three-dimensional structure of one WD- repeat protein and the assumption that the structure will be common to all members of this family has allowed subfamilies of WD-repeat proteins to be defined on the basis of probable surface similarity.

A perfect message : RNA surveillance and nonsense-mediated decay

TL;DR: It is suggested that mutated b-globin mRNA from a thalassemia patient was most of the available evidence can be integrated into a reported to be very low (Chang and Kan, 1979), forecommon model.

Identification and mutation analysis of the complete gene for Chediak-Higashi syndrome.

TL;DR: Analysis of the CHS polypeptide demonstrates that its modular architecture is similar to the yeast vacuolar sorting protein, VPS15, and this work describes the sequence of a human cDNA homologous to mouse beige, identify pathologic mutations and clarify the discrepancies of the previous reports.

Genome-wide RNA-seq analysis of human and mouse platelet transcriptomes

TL;DR: It is reported that RNA-seq provides unprecedented resolution of mRNAs that are expressed across the entire human and mouse genomes, and provides new insights into the human and murine platelet transcriptomes.
