Quality of Life in Patients with Phenylketonuria: A Systematic Review
This article reviews current researches on the impact of PKU on QoL. The review examines factors that may influence QoL, such as age, metabolic control, and treatment adherence. In this systematic review study, relevant articles were identified using a search strategy built with the keywords phenylketonuria, PKU, or hyperphenylalaninemia (or their synonyms) and QoL in Web of Science, Scopus, and PubMed databases. After identifying the articles, duplicates, reviews, scientific abstracts, articles published in languages other than English, and non relevant studies were excluded. The search strategy identified 951 records fro...

First successful outcomes of pegvaliase (PALYNZIQ) in children
CONCLUSIONS: This report addresses the potential broader applications of Pegvaliase in children, as well as its safety and tolerability in this age group. However, larger sample sizes and robust methodologies are required to validate such findings.PMID:38515136 | DOI:10.1186/s12920-024-01847-1 (Source: Molecular Medicine)

Identified PAH V230A and PAH V230I mutations in a family with diverse clinical presentations
In this study, we report an asymptomatic adult with mHPA who had never taken any medical intervention to control or lower her serum phenylalanine level (Phe). She had 179 μmol/L serum phenylalanine level and carried p.[V230A];[V230I] genotype. Her child was affected with phenylketonuria and had p.[V230A];[V230A] g enotype. Both pathogenic variants detected in the asymptomatic adult with mHPA were computationally analyzed to assess their pathogenicity and the p.V230I pathogenic variant was demonstrated to be responsible for the mHPA phenotype in the asymptomatic adult detected in this study. The findings in th is study c...

Targeting phenylalanine assemblies as a prospective disease-modifying therapy for phenylketonuria
Biophys Chem. 2024 Feb 27;308:107215. doi: 10.1016/j.bpc.2024.107215. Online ahead of print.ABSTRACTPhenylketonuria is characterized by the accumulation of phenylalanine, resulting in severe cognitive and neurological disorders if not treated by a remarkably strict diet. There are two approved drugs today, yet both provide only a partial solution. We have previously demonstrated the formation of amyloid-like toxic assemblies by aggregation of phenylalanine, suggesting a new therapeutic target to be further pursued. Moreover, we showed that compounds that halt the formation of these assemblies also prevent their resulting t...

Roles of the N-terminal motif in improving the activity and soluble expression of phenylalanine ammonia lyases in Escherichia coli
In this study, we aligned the amino acid sequences of AvPAL and PAL derived from Nostoc punctiforme (NpPAL) to obtain several mutants with enhanced activity, expression yield, and thermal stability via amino acid substitution and saturation mutagenesis at the N-terminal position. Enzyme kinetic experiments revealed that the kcat values of NpPAL-N2K, NpPAL-I3T, and NpPAL-T4L mutants were increased to 3.2-, 2.8-, and 3.3-fold that of the wild-type, respectively. Saturation mutagenesis of the fourth amino acid in AvPAL revealed that the kcat values of AvPAL-L4N, AvPAL-L4P, AvPAL-L4Q and AvPAL-L4S increased to 4.0-, 3.7-, 3.6-...

Recent trends in targeted delivery of smart nanocarrier-based microbial enzymes for therapeutic applications
Drug Discov Today. 2024 Feb 8:103915. doi: 10.1016/j.drudis.2024.103915. Online ahead of print.ABSTRACTSmart carrier-based immobilization has widened the use of enzymes for the treatment of several disorders. Large surface areas, tunable morphology, and surface modification ability aid the targeted and controlled release of therapeutic enzymes from such formulations. Smart nanocarriers, such as polymeric carriers, liposomes, and silica have also increased the stability, half-life, and permeability of these enzymes. In this review, summarize recent advances in the smart immobilization of microbial enzymes and their developm...
