Genetic and Pharmacological Inhibition of Autophagy Increases the Monoubiquitination of Non-Photosynthetic Phosphoenolpyruvate Carboxylase

open access: yesPlants, 2020
Phosphoenolpyruvate carboxylase (PEPC) is an enzyme with key roles in carbon and nitrogen metabolisms. The mechanisms that control enzyme stability and turnover are not well known.

β‐Aminoisobutyric Acid Alleviates Cisplatin‐Induced Muscle Atrophy by Regulating E3 Ubiquitin Ligases, Apoptosis, Amino Acid Metabolism, Autophagy, and Ferroptosis

open access: yesMedicine Bulletin, Volume 2, Issue 3, Page 256-267, June 2026.
ABSTRACT Background Cisplatin (CIS) is a widely used broad‐spectrum anticancer agent, but its clinical application is often limited by severe adverse effects, including skeletal muscle atrophy, which compromises patients' quality of life and treatment efficacy.

The Dual Role of Autophagy in Cancer: Mechanisms and Therapeutic Strategies

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Autophagy is a conserved cellular process degrading dysfunctional organelles and protein aggregates to maintain cell homeostasis, and it exhibits context‐dependent duality in cancer. Autophagy functions as a critical tumor‐suppressive mechanism by preventing DNA damage and mutation during tumor initiation.

Dengue Virus Utilizes NBR1 During Induced Lipophagy and for Viral Egress [PDF]

open access: yes
Dengue virus (DENV) infection induces a proviral lipophagy to mobilize lipids from the lipid droplet. Τhis study demonstrates that the selective autophagy receptor Neighbor of BRCA 1 (NBR1) is recruited to lipid droplets after DENV infection.

A Model of Autophagy Size Selectivity by Receptor Clustering on Peroxisomes

open access: yesFrontiers in Physics, 2017
Selective autophagy must not only select the correct type of organelle, but also must discriminate between individual organelles of the same kind so that some but not all of the organelles are removed.

Glutamine Deprivation Triggers Tribbles Homolog 3 Dependent G‐Quadruplex Resolution to Maintain DNA Repair and Tumor Survival

open access: yesAdvanced Science, Volume 13, Issue 27, 13 May 2026.
Glutamine deprivation triggers transient DNA damage yet activates adaptive repair in hepatocellular carcinoma cells. We identify TRIB3 as a stress‐induced nuclear scaffold that associates with DDX5 and G‐quadruplex DNA atBRCA1 andRAD51AP1 promoters. TRIB3 loss increases G4 accumulation, suppresses HR gene transcription, elevates γ‐H2A.X, and sensitizes

小而密低密度脂蛋白胆固醇对冠状动脉粥样硬化患者自噬诱导作用研究

open access: yesZhongguo shiyan zhenduanxue, 2021
目的探究小而密低密度脂蛋白胆固醇(sd LDL-C)对冠状动脉粥样硬化患者自噬诱导作用。方法选取自2018年1月1日-2020年5月30日间吉林大学第二医院收治拟行经皮冠状动脉介入术(PCI)的冠状动脉粥样硬化患者78例(粥样硬化组)和非粥样硬化冠脉病变患者45例(对照组)作为研究对象。观察两组患者血清sd LDL-C和冠脉标本中自噬相关蛋白表达水平。通过对粥样硬化组患者进行病变支数和狭窄程度亚组分析,观察其与sd LDL-C和自噬相关蛋白的相关性。结果粥样硬化组患者血清sd LDL-C、p62 ...

The Hemoprotein Hhy1 Promotes Heme‐Dependent Catalase Activity of Ctt1

open access: yesMolecular Microbiology, Volume 125, Issue 5, Page 389-411, May 2026.
A Schizosaccharomyces pombe strain deficient in heme (hem1Δ) and siderophore (Fc) biosynthesis, as well as high‐affinity iron (Fe) uptake (blue), was used to uncover the hemoprotein Hhy1 that promotes the heme‐dependent activity of the catalase Ctt1. In contrast, hhy1Δ cells exhibit reduced Ctt1 activity and increased sensitivity to oxidative stress ...

ERAD Component MoHrd3 Facilitates Pathogenicity and Establishes a Direct Regulation on Autophagy in Magnaporthe Oryzae

open access: yesAdvanced Science, Volume 13, Issue 24, 27 April 2026.
MoHrd3 plays a crucial role in regulating the pathogenicity of Magnaporthe oryzae. As an ER‐associated degradation component, MoHrd3 involves in ER stress‐triggered autophagy. It facilitates the fusion between the autophagosome and the vacuole via enhancing the interaction between MoAtg8 and MoYpt7.
