Elucidating the Role of Nrf2 Signaling Pathway in Mycoplasma Infections

Frontiers in Bioscience-Landmark
Mycoplasmas are the smallest cell-wall-less self-replicating prokaryotes. Mycoplasma species can be found within and outside cells as “silent parasites” that live intracellularly and as membrane surface parasites. The pathogen’s impact on respiratory health seems primarily caused by its capacity to alter immune responses, cause airway inflammation, and

Engineered Carbon Dots from a Traditional Herb Pair Orchestrate Concurrent Antioxidant and AP‐1‐Mediated Inflammation to Attenuate Renal Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
This study integrates two complementary traditional Chinese medicine components as precursors to synthesize bioactive AM‐AS@CDs. Compared with single‐component CDs, these dual‐component CDs exhibit enhanced antioxidant capacity and superior renoprotective effects.

Keap1/Nrf2 Signaling: A New Player in Thyroid Pathophysiology and Thyroid Cancer

Frontiers in Endocrinology, 2019
The Keap1/Nrf2 pathway is a key mediator of general redox and tissue-specific homeostasis. It also exerts a dual role in cancer, by preventing cell transformation of normal cells but promoting aggressiveness, and drug resistance of malignant ones ...

PANX2 Suppresses Lung Adenocarcinoma Progression by Inducing Disulfidptosis and Enhancing Antitumor Immunity

Advanced Science, EarlyView.
ABSTRACT Lung adenocarcinoma (LUAD) remains a leading cause of cancer mortality with limited therapeutic options. Disulfidptosis, a novel cell death modality driven by disulfide stress, represents a promising target, yet its regulation in LUAD is poorly defined. Here, we identify Pannexin 2 (PANX2) as a tumor suppressor in LUAD.

Bioactive Compounds Protect Mammalian Reproductive Cells from Xenobiotics and Heat Stress-Induced Oxidative Distress via Nrf2 Signaling Activation: A Narrative Review

Antioxidants
Oxidative stress occurs when there is an imbalance between the production of reactive oxygen species (ROS) and the body’s antioxidant defenses. It poses a significant threat to the physiological function of reproductive cells. Factors such as xenobiotics

Systems Approach Reveals Nuclear Factor Erythroid 2-Related Factor 2/Protein Kinase R Crosstalk in Human Cutaneous Leishmaniasis

Frontiers in Immunology, 2017
Leishmania parasites infect macrophages, causing a wide spectrum of human diseases, from cutaneous to visceral forms. In search of novel therapeutic targets, we performed comprehensive in vitro and ex vivo mapping of the signaling pathways upstream and ...

A Non‐Canonical Core Transcriptional Regulatory Circuit Orchestrates Chromatin Reprogramming to Drive Osimertinib Resistance in Non‐Small Cell Lung Cancer

Advanced Science, EarlyView.
A non‐canonical core transcriptional regulatory circuit, composed of ID3, SMAD3, and NR2F2, drives Osimertinib resistance in non‐small cell lung cancer through super‐enhancer‐mediated activation of EPAS1, which couples neuroendocrine differentiation with ferroptosis evasion.

SIRT6‐Mediated Deacetylation of ATF3 Promotes Silica‐Induced Lung Fibrosis by Enhancing its Nuclear Import via Binding to Importin α

Advanced Science, EarlyView.
SIRT6‐mediated ATF3 acetylation drives MGARP transcription and mitochondrial dysfunction in macrophages, promoting macrophage senescence and pulmonary fibrosis. Mechanistically, HSP70/Importin α competitively binds to ATF3, modulating its nuclear translocation.
