Mutation Analysis of PAH Gene in Phenylketonuria Patients from the North of Iran: Identification of Three Novel Pathogenic Variants

International Journal of Preventive Medicine
Background: There are more than 1100 different pathogenic variants in the phenylalanine hydroxylase (PAH) gene that are responsible for phenylketonuria (PKU) diseases, and the spectrum of these mutations varies in different ethnic groups.

High Protein Diet and Phenylalanine Hydroxylase Activities in Rats

Pteridines, 1989
The effects of a diet of 85% casein on the activities of the phenylalanine hydroxylases of rat liver and kidney have been compared. Whereas only the tetrahydrobiopterin-dependent activity of rat hepatic phenylalanine hydroxylase is significantly ...

Microarray analysis of spring barley cultivars displaying differing sensitivity to physiological leaf spot (PLS) [PDF]

, 2015
peer-reviewedPhysiological leaf spot (PLS) is a disorder of spring barley (Hordeum vulgare L.), which has become more pronounced in recent years. The initial symptoms are small chlorotic/brown spots on the upper four leaves, which may develop into ...

The multidimensional regulation roles and mechanisms of calcium in fruit quality

Journal of Integrative Plant Biology, EarlyView.
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...

Phenylalanine Hydroxylase Misfolding and Pharmacological Chaperones [PDF]

Current Topics in Medicinal Chemistry, 2013
Phenylketonuria (PKU) is a loss-of-function inborn error of metabolism. As many other inherited diseases the main pathologic mechanism in PKU is an enhanced tendency of the mutant phenylalanine hydroxylase (PAH) to misfold and undergo ubiquitin-dependent degradation. Recent alternative approaches with therapeutic potential for PKU aim at correcting the

ARF6 integrates auxin and gibberellin signaling to promote stone cell lignification in pear via the HB49‐MYB169 module

New Phytologist, EarlyView.
Summary Stone cells originate from secondary cell wall thickening and contain abundant lignin. Their excessive accumulation compromises pear fruit quality, yet the endogenous hormonal mechanisms governing stone cell formation remain unclear. Here, co‐expression network analysis using transcriptome data – the flesh of 206 sand pear accessions sampled at

A Near Telomere‐to‐Telomere Genome of Belamcanda chinensis Provides Insights Into Genome Evolution and the Biosynthesis of Characteristic Isoflavones

Plant Biotechnology Journal, EarlyView.
ABSTRACT Belamcanda chinensis is a non‐leguminous medicinal plant rich in bioactive isoflavones; however, the lack of a high‐quality reference genome has limited elucidation of its isoflavone biosynthetic and modification network. Here, we present the first near telomere‐to‐telomere genome assembly of B.

Chronic Immune Stimulation May Cause Moderate Impairment of Phenylalanine 4-hydroxylase

Pteridines, 2011
Phenylalanine (4)-hydroxylase (PAH, E.C. 1.14.16.1) is located mainly in liver and converts amino acid phenylalanine (Phe) to tyrosine (Tyr). In 'classical' phenylketonuria (PKU), PAH activity is reduced, whereas in 'atypical' PKU biosynthesis of the ...

Sweet Potato Gene Clusters Control Anthocyanin Biosynthesis and Leaf Morphology

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sweet potato (Ipomoea batatas) exhibits diversity in pigmentation and leaf morphology, yet the genetic architecture and regulatory organisation underlying these traits remain poorly resolved, particularly with respect to organ‐specific control.
