Abstract

The effects of interferon (IFN) alpha-2a treatment on platelet function were evaluated in 20 patients affected by essential thrombocythaemia (ET). Baseline data documented the well-known abnormalities of in vitro platelet aggregation and the constant presence of a delta-storage pool deficiency. The therapy in all patients reduced the platelet count, and in the majority of them caused a partial improvement of in vitro platelet aggregation. Although the mean intraplatelet ADP level improved during treatment, it always remained below the normal range documenting persistence of the delta-storage pool deficiency. The plasma beta-TG levels, which initially were high, significantly decreased during treatment, but the beta-TG ratio and the platelet beta-TG values always remained within the normal range--this suggests an absence of platelet activation either before or during therapy. Our results demonstrate that, despite significantly reducing the platelet count, IFN alpha-2a treatment only partially corrects the qualitative platelet abnormalities in ET.

A novel DPH5-related diphthamide-deficiency syndrome causing embryonic lethality or profound neurodevelopmental disorder.

PURPOSE: Diphthamide is a post-translationally modified histidine essential for messenger RNA translation and ribosomal protein synthesis. We present evidence for DPH5 as a novel cause of embryonic lethality and profound neurodevelopmental delays (NDDs). METHODS: Molecular testing was performed using exome or genome sequencing. A targeted Dph5 knockin mouse (C57BL/6Ncrl-Dph5em1Mbp/Mmucd) was created for a DPH5 p.His260Arg homozygous variant identified in 1 family. Adenosine diphosphate-ribosylation assays in DPH5-knockout human and yeast cells and in silico modeling were performed for the identified DPH5 potential pathogenic variants. RESULTS: DPH5 variants p.His260Arg (homozygous), p.Asn110Ser and p.Arg207Ter (heterozygous), and p.Asn174LysfsTer10 (homozygous) were identified in 3 unrelated families with distinct overlapping craniofacial features, profound NDDs, multisystem abnormalities, and miscarriages. Dph5 p.His260Arg homozygous knockin was embryonically lethal with only 1 subviable mouse exhibiting impaired growth, craniofacial dysmorphology, and multisystem dysfunction recapitulating the human phenotype. Adenosine diphosphate-ribosylation assays showed absent to decreased function in DPH5-knockout human and yeast cells. In silico modeling of the variants showed altered DPH5 structure and disruption of its interaction with eEF2. CONCLUSION: We provide strong clinical, biochemical, and functional evidence for DPH5 as a novel cause of embryonic lethality or profound NDDs with multisystem involvement and expand diphthamide-deficiency syndromes and ribosomopathies.

A mobile tryptophan is the intrinsic charge transfer donor in a flavoenzyme essential for nikkomycin antibiotic biosynthesis.

The flavoenzyme nikD is required for the biosynthesis of nikkomycin antibiotics. NikD exhibits an unusual long wavelength absorption band attributed to a charge transfer complex of FAD with an unknown charge transfer donor. NikD crystals contain an endogenous active site ligand. At least four different compounds are detected in nikD extracts, including variable amounts of two ADP derivatives that bind to the enzyme's dinucleotide binding motif in competition with FAD, picolinate (0.07 mol/mol of nikD) and an unknown picolinate-like compound. Picolinate, the product of the physiological catalytic reaction, matches the properties deduced for the active site ligand in nikD crystals. The charge transfer band is eliminated upon mixing nikD with excess picolinate but not by a reversible unfolding procedure that removes the picolinate-like compound, ruling out both compounds as the intrinsic charge transfer donor. Mutation of Trp355 to Phe eliminates the charge transfer band, accompanied by a 30-fold decrease in substrate binding affinity. The results provide definitive evidence for Trp355 as the intrinsic charge transfer donor. The indole ring of Trp355 is coplanar with or perpendicular to the flavin ring in "open" or "closed" crystalline forms of nikD, respectively. Importantly, a coplanar configuration is required for charge transfer interaction. Absorption in the long wavelength region therefore constitutes a valuable probe for monitoring conformational changes in solution that are likely to be important in nikD catalysis.

Bioinformatic discovery of novel bioactive peptides.

Short synthetic oligopeptides based on regions of human proteins that encompass functional motifs are versatile reagents for understanding protein signaling and interactions. They can either mimic or inhibit the parent protein's activity and have been used in drug development. Peptide studies typically either derive peptides from a single identified protein or (at the other extreme) screen random combinatorial peptides, often without knowledge of the signaling pathways targeted. Our objective was to determine whether rational bioinformatic design of oligopeptides specifically targeted to potentially signaling-rich juxtamembrane regions could identify modulators of human platelet function. High-throughput in vitro platelet function assays of palmitylated cell-permeable oligopeptides corresponding to these regions identified many agonists and antagonists of platelet function. Many bioactive peptides were from adhesion molecules, including a specific CD226-derived inhibitor of inside-out platelet signaling. Systematic screens of this nature are highly efficient tools for discovering short signaling motifs in molecular signaling pathways.
