mROS ‑calcium feedback loop promotes lethal ventricular arrhythmias and sudden cardiac death in early myocardial ischemia
Int J Mol Med. 2024 Jan;53(1):5. doi: 10.3892/ijmm.2023.5329. Epub 2023 Nov 24.ABSTRACTLethal ventricular arrhythmia‑sudden cardiac death (LVA‑SCD) occurs frequently during the early stage of myocardial ischemia (MI). However, the mechanism underlying higher LVA‑SCD incidence is still poorly understood. The present study aimed to explore the role of mitochondrial reactive oxygen species (mROS) and Ca2+ crosstalk in promoting LVA‑SCD in early MI. RyR2 S2814A mice and their wild‑type littermates were used. MitoTEMPO was applied to scavenge mitochondrial ROS (mROS). Mice were subjected to severe MI and the occurrenc...

Roles of vitamin K ‑dependent protein in biomineralization (Review)
Int J Mol Med. 2024 Jan;53(1):6. doi: 10.3892/ijmm.2023.5330. Epub 2023 Nov 24.ABSTRACTVitamin K (VK), a fat‑soluble vitamin, is well known as an anticoagulant in the clinic. It is essential for the post‑translational activation of VK‑dependent proteins (VKDPs) because hydroquinone VK is a cofactor of glutamine carboxylase. At present, 17 VKDPs are known, which are mainly involved in coagulation and calcification. When Glu residues are carboxylated to Gla residues, these proteins gain a higher calcium‑binding ability, which explains why VK has an important role in blood coagulation and biomineralization. However, t...

Inhibition of HDAC6 alleviates cancer ‑induced bone pain by reducing the activation of NLRP3 inflammasome
Int J Mol Med. 2024 Jan;53(1):4. doi: 10.3892/ijmm.2023.5328. Epub 2023 Nov 24.ABSTRACTCancer‑induced bone pain (CIBP) is characterized as moderate to severe pain that negatively affects the daily functional status and quality of life of patients. When cancer cells metastasize and grow in bone marrow, this activates neuroinflammation in the spinal cord, which plays a vital role in the generation and persistence of chronic pain. In the present study, a model of CIBP was constructed by inoculating of MRMT‑1 rat breast carcinoma cells into the medullary cavity of the tibia in male Sprague‑Dawley rats. Following two week...

Gab2 promotes the growth of colorectal cancer by regulating the M2 polarization of tumor ‑associated macrophages
Int J Mol Med. 2024 Jan;53(1):3. doi: 10.3892/ijmm.2023.5327. Epub 2023 Nov 8.ABSTRACTTumor‑associated macrophages (TAMs) are pivotal components in colorectal cancer (CRC) progression, markedly influencing the tumor microenvironment through their polarization into the pro‑inflammatory M1 or pro‑tumorigenic M2 phenotypes. Recent studies have highlighted that the Grb2‑associated binder 2 (Gab2) is a critical gene involved in the development of various types of tumor, including CRC. However, the precise role of Gab2 in mediating TAM polarization remains incompletely elucidated. In the present study, it was discovered ...

Single ‑cell sequencing, genetics, and epigenetics reveal mesenchymal stem cell senescence in osteoarthritis (Review)
Int J Mol Med. 2024 Jan;53(1):2. doi: 10.3892/ijmm.2023.5326. Epub 2023 Nov 8.ABSTRACTOsteoarthritis (OA) is a chronic joint disease characterized by articular cartilage degeneration, secondary bone hyperplasia, inadequate extracellular matrix synthesis and degeneration of articular cartilage. Mesenchymal stem cells (MSCs) can self‑renew and undergo multidirectional differentiation; they can differentiate into chondrocytes. Aging MSCs have a weakened ability to differentiate, and release various pro‑inflammatory cytokines, which may contribute to OA progression; the other mechanism contributing to OA is epigenetic regu...
