Molecular architecture of the human protein deacetylase Sirt1 and its regulation by AROS and resveratrol [PDF]

open access: yes, 2013
Sirtuins are NAD+-dependent protein deacetylases regulating metabolism, stress responses and ageing processes. Among the seven mammalian Sirtuins, Sirt1 is the physiologically best-studied isoform.

Engineering Neutrophil Vesicles for Synergistic Protection against Ischemia/Reperfusion Injury after Lung Transplant

open access: yesAdvanced Science, Volume 12, Issue 42, November 13, 2025.
Engineered neutrophil‐derived vesicles (SOD2‐Fer‐1@CVs) co‐delivering antioxidant and ferroptosis‐inhibitory agents enable inflammation‐targeted, ROS‐responsive therapy for ischemia–reperfusion injury in lung transplantation. Synergizing with ex vivo lung perfusion, this strategy alleviates oxidative stress and inflammation, restores vascular integrity,

Rhaponitin Reverses Cisplatin Resistance and Impairs Cancer Stemness Through HIF‐1α/MCT4/Wnt Pathway in Tongue Squamous Cell Carcinoma

open access: yesThe Kaohsiung Journal of Medical Sciences, Volume 41, Issue 11, November 2025.
ABSTRACT Rhaponitin (Rha) possesses anti‐tumor activity and mediates the transcriptional activity of hypoxia‐inducible factor (HIF)‐1α that affects cisplatin (Cis) resistance. However, whether Rha can lessen Cis resistance in tongue squamous cell carcinoma (TSCC) by mediating HIF‐1α activity is unclear. Cis‐resistant SCC9 (SCC9‐CisR) cells were treated

The oxygenase CAO-1 of Neurospora crassa is a resveratrol cleavage enzyme. [PDF]

open access: yes, 2013
The genome of the ascomycete Neurospora crassa encodes CAO-1 and CAO-2, two members of the carotenoid cleavage oxygenase family that target double bonds in different substrates. Previous studies demonstrated the role of CAO-2 in cleaving the C40 carotene

Piceatannol: A Potential Futuristic Natural Stilbene as Fetal Haemoglobin Inducer

open access: yesJOURNAL OF CLINICAL AND DIAGNOSTIC RESEARCH, 2013
Beta thalassaemia is an autosomal recessive inherited blood disorder which results in abnormal formation of Haemoglobin molecule and ineffective erythropoiesis. Patients need to be dependent on habitual blood transfusion and on unaffordable exorbitant therapies for continued existence.
