Phosphorylation of BOK at Ser-8 Blocks Its Ability to Suppress IP3R-Mediated Calcium Mobilization

The New Role of BOK Protein in Calcium Signaling Regulation Background Introduction BOK (Bcl-2-related ovarian killer) is a member of the Bcl-2 protein family and has long been thought to play a role in cell apoptosis. However, recent studies suggest that BOK may also have non-apoptotic functions, particularly in the regulation of calcium ion (Ca²⁺...

The SIRT5-JIP4 Interaction Promotes Osteoclastogenesis by Modulating RANKL-Induced Signaling Transduction

SIRT5-JIP4 Interaction Promotes Osteoclastogenesis by Modulating RANKL-Induced Signaling Transduction Research Background Osteoporosis is a common bone disease characterized by reduced bone density and disrupted bone microstructure, leading to an increased risk of fractures. Osteoclasts, the primary cells responsible for bone resorption, play a cri...

Signal Integrator Function of CXXC5 in Cancer

Signal Integrator Function of CXXC5 in Cancer Academic Background CXXC5 (CXXC-type zinc finger protein 5) is a member of the ZF-CXXC protein family and plays a pivotal role in signal integration and information transfer within the cellular signaling network. By regulating multiple signaling pathways (such as Wnt/β-catenin, TGF-β/BMP, ATM/p53, etc.)...

Integrative Analysis of Ewing’s Sarcoma Reveals the MIF-CD74 Axis as a Target for Immunotherapy

Discovery of a New Immunotherapy Target for Ewing Sarcoma Background Introduction Ewing sarcoma (Ewing’s sarcoma, EWS) is a common pediatric bone cancer, accounting for approximately 2% of childhood cancers. Despite significant advances in immune checkpoint inhibitors (ICIs) and CAR-T cell therapy in various cancers, their efficacy in Ewing sarcoma...

Targeting the ERK1/2 and p38 MAPK Pathways Attenuates Golgin-97 Depletion-Induced Cancer Progression in Breast Cancer

Targeting ERK1/2 and p38 MAPK Pathways Attenuates Golgin-97 Depletion-Induced Breast Cancer Progression Research Background Breast cancer is the most common type of cancer among women worldwide, with triple-negative breast cancer (TNBC) having a particularly high metastasis rate and poor prognosis. TNBC lacks expression of estrogen receptor, proges...

Histone Demethylases in Autophagy and Inflammation

The Role of Histone Demethylases in Autophagy and Inflammation Background Introduction Autophagy is an essential lysosomal degradation process in eukaryotic cells, playing a critical role in cellular component renewal and homeostasis maintenance. Dysregulation of autophagy is associated with various diseases, including cancer, inflammatory diseases...

Klebsiella pneumoniae-derived extracellular vesicles impair endothelial function by inhibiting SIRT1

Klebsiella pneumoniae-Derived Extracellular Vesicles Impair Endothelial Function by Inhibiting SIRT1 Academic Background Hypertension is a global health issue with a complex pathogenesis involving multiple factors. In recent years, the role of gut microbiota in hypertension has garnered significant attention. Studies have shown that dysbiosis of th...

Role of Sirtuins in Obesity and Osteoporosis: Molecular Mechanisms and Therapeutic Targets

The Role of Sirtuins in Obesity and Osteoporosis and Their Therapeutic Potential Academic Background Obesity and osteoporosis (OP) are increasingly severe public health issues worldwide. Obesity is not only closely related to metabolic diseases such as cardiovascular diseases and diabetes but also has a complex association with the occurrence of os...

Co-targeting of Glial Activation and Inflammation by tsRNA-Gln-I-0095 for Treating Retinal Ischemic Pathologies

Study on the Regulatory Mechanism of tsRNA-Gln-i-0095 in Retinal Ischemia-Reperfusion Injury Academic Background Retinal ischemia-reperfusion (I/R) injury is a critical pathological mechanism in various ocular diseases, including glaucoma, central retinal vein occlusion, and retinopathy of prematurity. I/R injury leads to the death of retinal gangl...

Regulation of Calcium Homeostasis in Endoplasmic Reticulum–Mitochondria Crosstalk: Implications for Skeletal Muscle Atrophy

The Critical Role of Calcium in Skeletal Muscle Function and Its Interaction with Mitochondria and the Endoplasmic Reticulum Academic Background Calcium ions (Ca²⁺) are crucial intracellular signaling molecules, particularly in the excitation-contraction coupling (ECC) of skeletal muscle. The contraction of skeletal muscle relies on the release and...
