Exploring Tumor-Immune Interactions in Co-Culture Models of T Cells and Tumor Organoids Derived from Patients.

The use of patient-derived tumor tissues and cells has led to significant advances in personalized cancer therapy and precision medicine. The advent of genomic sequencing technologies has enabled the comprehensive analysis of tumor characteristics. The three-dimensional tumor organoids derived from self-organizing cancer stem cells are valuable ex vivo models that faithfully replicate the structure, unique features, and genetic characteristics of tumors.

Methylglyoxal-Derived Advanced Glycation End Products (AGE4) Promote Cell Proliferation and Survival in Renal Cell Carcinoma Cells through the RAGE/Akt/ERK Signaling Pathways.

Advanced glycation end products (AGEs) are the products formed through a non-enzymatic reaction of reducing sugars with proteins or lipids. There is a potential for toxicity in the case of AGEs produced through glycation with dicarbonyl compounds including methylglyoxal, glyoxal, and 3-deoxyglucosone. The AGEs bind the receptor for advanced glycation end products (RAGE) and stimulate the mitogen-activated protein (MAP) kinase signaling pathway that can increase the production of matrix metalloproteinases (MMPs).

Methylglyoxal-Derived Advanced Glycation End Product (AGE4)-Induced Apoptosis Leads to Mitochondrial Dysfunction and Endoplasmic Reticulum Stress through the RAGE/JNK Pathway in Kidney Cells.

Advanced glycation end products (AGEs) are formed via nonenzymatic reactions between reducing sugars and proteins. Recent studies have shown that methylglyoxal, a potent precursor for AGEs, causes a variety of biological dysfunctions, including diabetes, inflammation, renal failure, and cancer. However, little is known about the function of methylglyoxal-derived AGEs (AGE4) in kidney cells.

Methylglyoxal-derived advanced glycation end products induce matrix metalloproteinases through activation of ERK/JNK/NF-κB pathway in kidney proximal epithelial cells.

The accumulation of reactive α-dicarbonyl leading to advanced glycation end products (AGEs) have been linked to pathophysiological diseases in many studies, such as atherosclerosis, cataract, cancer, and diabetic nephropathy. Glycation-generated AGEs increase the expression of inflammatory cytokines by transferring signals to the cell by binding them to the receptor for AGEs (RAGE) on their cell surface. The effect of methylglyoxal-derived AGEs (AGE-4) on the induction of matrix metalloproteinases (MMPs) in rat ordinary kidney cells (NRK-52E) was explored in this research, among other AGEs.
