The Interaction Between Vasculogenic Mimicry and the Immune System: Mechanistic Insights and Dual Exploration in Cancer Therapy.

Cell Prolif

January 2025

Department of Nursing, Sichuan Clinical Research Center for Cancer, Sichuan Cancer Hospital & Institute, Sichuan Cancer Center, University of Electronic Science and Technology of China, Chengdu, China.

Vasculogenic mimicry (VM) represents a novel form of angiogenesis discovered in numerous malignant tumours in recent years. Unlike traditional angiogenesis, VM facilitates tumour blood supply independently of endothelial cells by enabling tumour cells to form functional vascular networks. This phenomenon, where tumour cells replace endothelial cells to form tubular structures, plays a pivotal role in tumour growth and metastasis.

Department of Surgery of Spine and Spinal Cord, Henan Provincial People's Hospital, People's Hospital of Zhengzhou University, People's Hospital of Henan University, No.7 Weiwu Road, Zhengzhou, Henan, 450003, China.

Osteoarthritis (OA) is an age-related degenerative joint disease, prominently influenced by the pro-inflammatory cytokine interleukin-6 (IL-6). Although elevated IL-6 levels in joint fluid are well-documented, the uneven cartilage degeneration observed in knee OA patients suggests additional underlying mechanisms. This study investigates the role of interleukin-6 receptor (IL-6R) in mediating IL-6 signaling and its contribution to OA progression.

[Free gingival graft for augmenting peri-implant keratinized mucosa].

Zhonghua Kou Qiang Yi Xue Za Zhi

January 2025

Clinic of Zhujiang New Town,Hospital of Stomatology, Guanghua School of Stomatology, Sun Yat-sen University & Guangdong Provincial Key Laboratory of Stomatology, Guangzhou 510623, China.

Insufficient keratinized mucosa is a common clinical problem. Although there is no consistent data on the long-term success of implant restorations relative to the presence or absence of peri-implant keratinized mucosa, it is widely accepted that the presence of keratinized mucosa width<2 mm is associated with increased biofilm accumulation, soft-tissue inflammation, and mucosal recession. Free gingival graft (FGG) is the standard surgical intervention for augmenting the width of keratinized gingiva.

Redox imbalance, including excessive production of reactive oxygen species (ROS) caused by mitochondrial dysfunction and insufficient endogenous antioxidant capacity, is the primary cause of myocardial ischemia‒reperfusion (I/R) injury. In the exploration of reducing myocardial I/R injury, it is found that protecting myocardial mitochondrial function after reperfusion not only reduces ROS bursts but also inhibits cell apoptosis triggered by the release of cytochrome c. Additionally, nuclear factor erythroid 2-related factor 2 (Nrf2) is considered a potential therapeutic target for treating myocardial I/R injury by enhancing the cellular antioxidant capacity through the induction of endogenous antioxidant enzymes.
