Structure of human biliverdin IXβ reductase, an early fetal bilirubin IXβ producing enzyme

, 2001
Biliverdin IXβ reductase (BVR-B) catalyzes the pyridine nucleotide-dependent production of bilirubin-IXβ, the major home catabolite during early fetal development.

BVR-A Deficiency Leads to Autophagy Impairment through the Dysregulation of AMPK/mTOR Axis in the Brain—Implications for Neurodegeneration

Antioxidants, 2020
Biliverdin reductase-A (BVR-A) impairment is associated with increased accumulation of oxidatively-damaged proteins along with the impairment of autophagy in the brain during neurodegenerative disorders.

Osimertinib Resistance in EGFR‐Mutated Non–Small Cell Lung Cancer: Mechanisms and Therapeutic Strategies

MedComm, Volume 7, Issue 7, July 2026.
This review illustrates the key mechanisms of osimertinib resistance in EGFR‑mutant NSCLC, including EGFR‑dependent mutations, bypass pathway activation, and SMARCA4‑mediated epigenetic regulation. We also summarize emerging targeted therapies and future perspectives to overcome EGFR‑TKI resistance.

Acute pain transfusion reaction in a patient with thalassemia: In‐depth characterization of short‐ and long‐term phenotypes

Transfusion, Volume 66, Issue 7, Page 1299-1315, July 2026.
Abstract Background Acute pain transfusion reaction (APTR) is a rare, under‐recognized condition of unknown etiology. It can cause significant distress in recipients, necessitating symptomatic management and, occasionally, hospitalization. Study Design and Methods Here, we present an APTR event in an adult subject with transfusion‐dependent thalassemia

Inactivation of phytochrome- and phycobiliprotein-chromophore precursors by rat liver biliverdin reductase

, 1993
The phytochrome chromophore precursor, 3E-phytochromobilin, and the phycobiliprotein chromophore precursors, 3E-phycocyanobilin and 3E-phycoerythrobilin, are enzymatically converted to novel rubinoid products by purified rat liver biliverdin reductase ...

Metal‐dependent regulated cell death: Molecular architecture and translational frontiers

iMeta, Volume 5, Issue 3, June 2026.
Intracellular metal dyshomeostasis orchestrates distinct regulated cell death programs, including iron‐driven ferroptosis, copper‐mediated cuproptosis, calcicoptosis, newly designated zincoptosis, mnoptosis, and coptosis. This review systematically delineates their molecular architectures—spanning from Sorafenib‐induced lipid peroxidation and ...

Biliverdin Reductase B Dynamics Are Coupled to Coenzyme Binding [PDF]

Journal of Molecular Biology, 2018
Biliverdin reductase B (BLVRB) is a newly identified cellular redox regulator that catalyzes the NADPH-dependent reduction of multiple substrates. Through mass spectrometry analysis, we identified high levels of BLVRB in mature red blood cells, highlighting the importance of BLVRB in redox regulation.

Loss of biliverdin reductase-A favors Tau hyper-phosphorylation in Alzheimer's disease

Neurobiology of Disease, 2019
Hyper-active GSK-3β favors Tau phosphorylation during the progression of Alzheimer's disease (AD). Akt is one of the main kinases inhibiting GSK-3β and its activation occurs in response to neurotoxic stimuli including, i.e., oxidative stress.

Red blood cell membrane proteome as a reporter of disease severity, transfusion impact and genetic background in transfusion‐dependent β‐thalassaemia

British Journal of Haematology, Volume 208, Issue 6, Page 1980-1992, June 2026.
Summary Omics technologies have transformed research in haemoglobinopathies, yet the proteome of RBCs remains largely unexplored in transfusion‐dependent thalassaemia (TDT). In this proteomic analysis, Red blood cell (RBC) membranes from 48 adults with TDT were compared with healthy controls.

Bilirubin as a Modulator of WNK1 Protein Signaling: Implications for Neuroinflammatory Diseases

Advanced Science, Volume 13, Issue 27, 13 May 2026.
ABSTRACT Previously regarded merely as a potentially harmful waste product of heme catabolism, bilirubin has now emerged as a pleiotropic molecule with potent antioxidant, anti‐inflammatory, and hormone‐like properties. Recent findings have revealed protective effects against cardiovascular, metabolic, autoimmune, and neoplastic diseases, as well as ...
