Phenolic compounds in Chinese botanical medicines can ameliorate these pathological effects through ROS production inhibition and inflammatory signaling cascade suppression, thereby conferring therapeutic benefits in nephropathic conditions (Sahakyan et al., 2022)
Its core molecular mechanisms involve the collapse of the antioxidant defense system, particularly the inactivation of glutathione peroxidase 4 (GPX4), inhibition of the cystine/glutamate antiporter (System Xc - ), and dysregulation of the ferroptosis suppressor protein 1 (FSP1) pathway ( - supports GPX4 function by maintaining the supply of cysteine and GSH, whereas FSP1 independently inhibits lipid peroxidation by reducing the level of ubiquinone (CoQ10), thereby preventing ferroptosis ( 2+ , thereby promoting ferroptosis and suppressing tumor growth ( The tumor immune microenvironment (TIME) of GBM is characterized by highly immunosuppressive characteristics, marked by the polarization of tumor-associated macrophages (TAMs) toward the M2 phenotype, T-cell functional exhaustion, excessive infiltration of regulatory T cells (Tregs), and high expression of the immune checkpoint molecules PD1/PD-L1 ( Figure 1 ) The unique TIME of GBM not only promotes tumor cell growth and invasion but also limits the efficacy of existing chemotherapy and radiotherapy ( + T-cell exhaustion and Treg enrichment further constrain cytotoxic T lymphocyte (CTL) activity, impairing antitumor immunity and facilitating immune escape ( Figure 1 Metabolic alterations are considered key drivers in regulating the suppressive TIME of GBM

However, our knowledge of ongoing nephrogenesis in preterm humans is limited to a few postmortem studies, showing abnormalities in postnatal nephrogenesis in preterm born individuals ( Accelerated Aging and Oxidative Stress in Preterm Infants Preterm infants are known to have a shortened lifespan and acceleration of aging in large part due to cardiovascular disease, diabetes mellitus and chronic kidney disease (CKD) (72)
In contrast to ALMT1-mediated GABA transport, the presence of Al 3+ blocks the influx of GABA from the apoplast to the cytoplasm during ALMT1 transport, while it does not affect the GABA transport facilitated by GAT1 (Long et al
