Impact of Efavirenz on Heme Protein Induction and Biomarkers: Insights From In Vitro Experiments and a Clinical Study

open access: yesClinical and Translational Science, Volume 19, Issue 3, March 2026.
ABSTRACT Coproporphyrin I (CPI) is increasingly recognized as a reliable endogenous biomarker for hepatic OATP1B transporters. However, confounding mechanisms such as increased heme biosynthesis driven by induction of CYP enzymes, which are hemoproteins, may affect CPI levels independently of OATP1B1 inhibition. The aim of this study was to investigate

Identification and Validation of Potential Diagnostic Biomarkers for Pulmonary Arterial Hypertension Based on Gene Expression Profiling

open access: yesPulmonary Circulation
Pulmonary arterial hypertension (PAH) is a life‐threatening condition characterized by elevated pulmonary vascular resistance. Despite recent advances, early diagnosis remains challenging due to nonspecific symptoms. By utilizing RNA sequencing (RNA‐seq)

Identification of potential diagnostic biomarkers for systemic juvenile idiopathic arthritis by integrative transcriptomic analysis

open access: yesAutoimmunity
The current diagnostic criteria for systemic juvenile idiopathic arthritis (sJIA) lack specificity. Diagnostic biomarkers are in urgent need to help with the early diagnosis of sJIA. Gene expression data of a JIA cohort study from Gene Expression Omnibus

Murine erythroid 5‐aminolevulinate synthase: Adenosyl‐binding site Lys221 modulates substrate binding and catalysis

open access: yesFEBS Open Bio, 2015
5‐Aminolevulinate synthase (ALAS) catalyzes the initial step of mammalian heme biosynthesis, the condensation between glycine and succinyl‐CoA to produce CoA, CO2, and 5‐aminolevulinate. The crystal structure of Rhodobacter capsulatus ALAS indicates that

Anti-Correlation between the Dynamics of the Active Site Loop and C-Terminal Tail in Relation to the Homodimer Asymmetry of the Mouse Erythroid 5-Aminolevulinate Synthase

open access: yes, 2018
Biosynthesis of heme represents a complex process that involves multiple stages controlled by different enzymes. The first of these proteins is a pyridoxal 5′-phosphate (PLP)-dependent homodimeric enzyme, 5-aminolevulinate synthase (ALAS), that ...

Onset of X-linked sideroblastic anemia in the fourth decade

open access: yesHaematologica, 2004
We report the case of a 40-year female who manifested late onset, pyridoxine-refractory X-linked sideroblastic anemia, heterozygous for the first described frameshift ALAS2 mutation, CD506-507 (-C).

Validation of whole-blood transcriptome signature during microdose recombinant human erythropoietin (rHuEpo) administration

open access: yesBMC Genomics, 2017
Background Recombinant human erythropoietin (rHuEpo) can improve human performance and is therefore frequently abused by athletes. As a result, the World Anti-Doping Agency (WADA) introduced the Athlete Biological Passport (ABP) as an indirect method to ...

The major splice variant of human 5-aminolevulinate synthase-2 contributes significantly to erythroid heme biosynthesis

open access: yes, 2004
The initial step of the heme biosynthetic pathway in erythroid cells is catalyzed by an erythroid-specific isoform of 5-aminolevulinate synthase-2 (ALAS2).

TNF-α mutation affects the gene expression profiles of patients with multiple trauma

open access: yesEuropean Journal of Inflammation, 2015
Multiple trauma can induce sepsis and organ failure, even threaten people’s lives. To further study the mechanisms of multiple trauma, we analyzed microarray of GSE5760.
