Muscle wasting in cancer cachexia: Mechanisms and the role of exercise
Abstract Cancer cachexia (CC) is a multifactorial disease marked by a severe and progressive loss of lean muscle mass and characterized further by inflammation and a negative energy/protein balance, ultimately leading to muscle atrophy and loss of muscle tissue.

LMP is responsible for lysosomal dysfunction in IDD. The lipid composition changes in the lysosomal membrane, mediated by PLA2G15, are the cause of LMP. The C/EBPα significantly promotes PLA2G15 expression under PA overload stress. Inhibition of PLA2G15 alleviates PA‐induced LMP by inhibiting the hydrolysis of lysosomal membrane phospholipids.

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

Hyperoxia Causes Mitochondrial Fragmentation in Pulmonary Endothelial Cells by Increasing Expression of Pro-Fission Proteins [PDF]
Objective—We explored mechanisms that alter mitochondrial structure and function in pulmonary endothelial cells (PEC) function after hyperoxia. Approach and Results—Mitochondrial structures of PECs exposed to hyperoxia or normoxia were visualized and ...

Targeting EZH2 in Cancer: From Molecular Mechanisms to Clinical Translation
The abnormal overexpression or gain‐of‐function mutations of EZH2 play a significant role in cancer occurrence and progression, highlighting the importance and potential of EZH2 as a cancer biomarker. Therefore, screening for effective and safe small‐molecule inhibitors, degraders, and natural compounds targeting EZH2 through preclinical cancer models ...

Autophagy-deficient breast cancer shows early tumor recurrence and escape from dormancy [PDF]
Breast cancer patients who initially respond to cancer therapies often succumb to distant recurrence of the disease. It is not clear why people with the same type of breast cancer respond to treatments differently; some escape from dormancy and relapse ...

Regulated Cell Death in Idiopathic Pulmonary Fibrosis
This graphical abstract illustrates regulated cell death (RCD) across key pulmonary cell types—including alveolar epithelial cells, fibroblasts, macrophages, and endothelial cells—modulated through a dynamic death modulation network within the IPF microenvironment.

SIRT4 positively regulates autophagy via ULK1, but independently of HDAC6 and OPA1
Cells expressing SIRT4 (H161Y), a catalytically inactive mutant of the sirtuin SIRT4, fail to upregulate LC3B‐II and exhibit a reduced autophagic flux under stress conditions. Interestingly, SIRT4(H161Y) promotes phosphorylation of ULK1 at S638 and S758 that are associated with inhibition of autophagy initiation.

Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

HSP90α is significantly upregulated in platelets from sepsis patients, with its origin from megakaryocyte‐derived trafficking. Furthermore, activated platelets secrete HSP90α into the extracellular space in both free and exosome‐associated forms. Finally, extracellular HSP90α directly engages TLR4 on neutrophils to induce autophagy, leading to NET ...
