Transcriptomic study in explanted liver from a patient with acute intermittent porphyria

open access: yesJIMD Reports, 2023
Acute intermittent porphyria (AIP) is a rare disease caused by a deficiency of hydroxymethylbilane synthase (HMBS), the third enzyme of the heme‐synthesis pathway. Decreased enzymatic activity in the liver induces an overproduction of heme‐precursors and

Gene Dosage Sensitivity and Human Genetic Diseases

open access: yesJournal of Inherited Metabolic Disease, Volume 48, Issue 4, July 2025.
ABSTRACT Here we review the historical background and contemporary insights into genetic dominance, focusing on haploinsufficiency (HI), that is, when the function of only one allele of a gene is not enough to ensure a normal phenotype in a diploid organism.

A Prospective, Blinded Study of Symptom Prevalence and Specificity of Porphyrin Precursors in Carriers of Acute Hepatic Porphyria

open access: yesLiver International, Volume 45, Issue 7, July 2025.
ABSTRACT Background and Aims This study aimed to characterise symptoms and assess the prevalence of elevated urine porphyrin precursors in first‐degree relatives of acute hepatic porphyria (AHP) patients who have never experienced acute attacks and had no previous AHP genetic or biochemical testing.

No evidence for sylvatic cycles of chikungunya, dengue and Zika viruses in African green monkeys (Chlorocebus aethiops sabaeus) on St. Kitts, West Indies

open access: yesParasites & Vectors, 2020
Background Dengue, chikungunya and Zika viruses (DENV, CHIKV and ZIKV) are transmitted in sylvatic transmission cycles between non-human primates and forest (sylvan) mosquitoes in Africa and Asia.

Increased Mitochondrial Superoxide Level Is Partially Associated With Vemurafenib‐Induced Renal Tubular Toxicity

open access: yesBasic &Clinical Pharmacology &Toxicology, Volume 136, Issue 4, April 2025.
Vemurafenib (VEM) induces renal tubular toxicity through mitochondrial dysfunction and lysosomal abnormalities. Superoxide production is a key factor, and mitochondrial antioxidant XJB‐5‐131 partially alleviated this toxicity. Autophagy impairment is also suggested.

Liver transplantation and primary liver cancer in porphyria

open access: yesLiver International, Volume 45, Issue 3, March 2025.
Abstract The porphyrias are a heterogeneous group of metabolic disorders that result from defects in heme synthesis. The metabolic defects are present in all cells, but symptoms are mainly cutaneous or related to neuropathy. The porphyrias are highly relevant to hepatologists since patients can present with symptoms and complications that require liver

Zinc signaling controls astrocyte‐dependent synapse modulation via the PAF receptor pathway

open access: yesJournal of Neurochemistry, Volume 169, Issue 2, February 2025.
Low zinc bioavailability triggers inflammatory signaling through chronic activation of astrocytes via the PAFR. Active astrocytes release ROS, metabolites, and cytokines that affect synapse formation in developing neurons. Adequate zinc status prevents astrocyte (over)activation. PAFR, platelet activation factor receptor.

First report of Babesia gibsoni in Central America and survey for vector-borne infections in dogs from Nicaragua

open access: yesParasites & Vectors, 2014
Background Although many vector-borne diseases are important causes of morbidity and mortality in dogs in tropical areas and potential zoonoses, there is little information on these conditions in Central America.
