Glucuronan lyases from family PL7 use a Tyr/Tyr syn β-elimination catalytic mechanism for glucuronan breakdown

open access: yes
TpPL7A and TpPL7B, members of CAZy family PL7, act as β-glucuronan lyases. TpPL7A diverges by lacking the catalytic histidine, identified as the Brønsted base in PL7 alginate lyases.

A horizontally transferred bacterial gene for pantothenic acid biosynthesis regulates diapause and reproduction in the spider mite Amphitetranychus viennensis

open access: yesInsect Science, EarlyView.
A bacterial‐derived AvPBL gene encoding a pantothenate‐β‐alanine ligase was identified in Amphitetranychus viennensis. RNAi silencing of AvPBL reduced pantothenic acid production, impairing reproduction and diapause induction, while pantothenic acid supplementation rescued these phenotypes.

High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

open access: yesIntegrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Hydroxynitrile Lyases: Biological Sources and Application as Biocatalysts

open access: yesFood Technology and Biotechnology, 2004
We review the state of the art regarding the application of hydroxynitrile lyases to obtain, enantioselectively, (R)- and (S)-cyanohydrins of aldehydes and ketones.

Seasonal Dynamics of Community and Function of Gut Microbiome in Taihangshan Macaque (Macaca mulatta tcheliensis): Inferred From Metagenomic Data

open access: yesIntegrative Zoology, EarlyView.
A total of 435 non‐redundant metagenome‐assembled genomes (MAGs) were obtained from fecal samples of Taihangshan macaque across all four seasons. The alpha diversity of the gut microbiome in spring and winter was significantly higher than in summer and autumn. Furthermore, marked differences were detected in functional pathways and carbohydrate enzymes

Art v 1 and Amb a 4 Co‐Sensitization Identifies Italian Patients at Risk for Mugwort‐Celery‐Spice Syndrome

open access: yesAllergy, EarlyView.
Three molecular profiles identified among Art v 1/Amb a 4‐sensitized patients: Art v 1 monosensitization, Amb a 4 monosensitization, and dual sensitization to both allergens. Art v 1 monosensitization was predominantly associated with allergic rhinitis, reflecting a classical airborne allergy pattern.

Testicular Biopsies in Adolescent and Adult Andrological Patients: The EAA Clinical Guidelines

open access: yesAndrology, EarlyView.
ABSTRACT Background Histological evaluation of testicular tissue is central to the assessment of infertile men, particularly those at an increased risk of testicular germ cell tumors (TGCT). Traditionally, testicular biopsies have been used primarily for diagnostic purposes, such as the detection of germ cell neoplasia in situ (GCNIS). With advances in

Re‐thinking peripheral dysfunctions in obesity: The emerging role of sulphaceutics and sulphanutraceutics

open access: yesBritish Journal of Pharmacology, EarlyView.
Obesity is a chronic, relapsing, multisystem disease in which cardiometabolic risk arises from excess adiposity and progressive dysfunction of peripheral organs, ultimately disrupting endocrine and metabolic crosstalk among tissues. Within this network, sulphur‐based biology, centred on hydrogen sulphide and related reactive sulphur species, has ...

Pleiotropic Roles of FBXO11 in Tumorigenesis: Implications for Targeted Therapy

open access: yesCancer Science, EarlyView.
This complex comprises of scaffold CUL1, SKP1, RBX1 and FBXO11 receptor. The substrate is phosphorylated by specific kinase enzyme and recognized by the substrate recognition domain. FBXO11 targets numerous substrates for ubiquitination and degradation, FBXO11 substrates mainly include Snail, ZEB1, p53, BCL6, CDT2, CIITA, Cdc25a, hnRNPA2B1, SAMD1 and ...
