Abstract
Phthalates are common plasticizers present in medical-grade plastics and other everyday products. Di-ethylhexyl phthalate (DEHP) has been noted as a causative risk factor for the initiation and augmentation of cardiovascular functional disorders. G-CSF is a glycoprotein found in numerous tissues throughout the body and is currently applied in clinical practice and has been tested in congestive heart failure. We aimed to examine in depth the effect of DEHP on the histological and biochemical structure of the cardiac muscle in adult male albino rats and the mechanisms underlying the possible ameliorative effect of G-CSF. Forty-eight adult male albino rats were divided into control group, DEHP group, DEHP+ G-CSF group and DEHP-recovery group. We measured serum levels of aspartate aminotransferase (AST), creatine kinase MB isoenzyme (CK-MB) and lactate dehydrogenase (LDH). Left ventricular sections were processed for light and electron microscope examination, and immunohistochemical staining of Desmin, activated Caspase-3 and CD34. DEHP significantly increased enzyme levels, markedly distorted the normal architecture of cardiac muscle fibers, downregulated Desmin protein levels and enhanced fibrosis, and apoptosis. G-CSF treatment significantly decreased the enzyme levels compared to DEHP group. It enhanced CD34 positive stem cells recruitment to injured cardiac muscle, therefore improved the ultrastructural features of most cardiac muscle fibers via anti-fibrotic and anti-apoptotic effects in addition to increased Desmin protein expression levels. The recovery group showed partial improvement due to persistent DEHP effect. In conclusion, administration of G-CSF effectively corrected the histopathological, immunohistochemical and biochemical alterations in the cardiac muscle after DEHP administration by stem cells recruitment, Desmin protein regulation, antifibrotic and antiapoptotic mechanisms.

Toxicol Res (Camb) 2023; 12:332-343.

Abstract
Plasticizer di(2-ethylhexyl) phthalate (DEHP) is employed to make polyethylene polymers. Some studies in epidemiology and toxicology have shown that DEHP exposure over an extended period may be hazardous to the body, including nephrotoxicity, and aggravate kidney damage in the context of underlying disease. However, studies on the toxicity of DEHP in diabetes-induced kidney injury have been rarely reported. Using a high-fat diet (HFD) and streptozotocin (STZ, 35 mg/kg)-induced kidney injury in mice exposed to various daily DEHP dosages, we explored the impacts of DEHP on diabetes-induced kidney injury. We discovered that DEHP exposure significantly promoted the renal inflammatory response and oxidative stress in mice, with increased P-p38 and P-p65 protein levels and exacerbated the loss of podocin. The same findings were observed in vitro after stimulation of podocytes with high glucose (30 mmol/L) and exposure to DEHP. Our results suggest that DEHP exacerbates diabetes-induced kidney injury by mediating oxidative stress and activating p38MAPK/NF-κB.

Mol Biol Rep 2023; 50:3469-3478. [PMID: 36765018 DOI: 10.1007/s11033-023-08310-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Accepted: 01/26/2023] [Indexed: 02/12/2023]
Abstract
BACKGROUND Metformin, a first-line oral anti-diabetic drug, has recently been reported to exert protective effect on various cardiovascular diseases. However, the potential role of metformin in ethanol-induced cardiomyocyte injury is still unknown. Therefore, this study was aimed to investigate the effect of metformin on ethanol-induced cardiomyocyte injury and its underlying mechanism. METHODS AND RESULTS H9c2 cardiomyocytes were exposed to ethanol for 24 h to establish an ethanol-induced cardiomyocyte injury model, and followed by treatment with metformin in the presence or absence of Lapatinib (an ErbB2 inhibition). CCK8 and LDH assays demonstrated that metformin improved cell viability in cardiomyocytes exposed to ethanol. Furthermore, metformin suppressed cardiomyocyte apoptosis and reduced the expressions of apoptosis-related proteins (Bax and C-CAS-3). In addition, our results showed that metformin activated the AKT/Nrf2 pathway, and then promoted Nrf2 nuclear translocation and the transcription of its downstream antioxidant genes (HO-1, CAT and SOD2), thereby inhibiting oxidative stress. Interestingly, we found that ErbB2 protein expression was significantly inhibited in ethanol-treated cardiomyocytes, which was markedly reversed by metformin. In contrast, Lapatinib largely abrogated the activation of AKT/Nrf2 signaling by metformin, accompanied by the increases in oxidative stress and cardiomyocyte apoptosis, indicating that metformin prevented ethanol-induced cardiomyocyte injury in an ErbB2-dependent manner. CONCLUSION In summary, our study provides the first evidence that metformin protects cardiomyocyte against ethanol-induced oxidative stress and apoptosis by activating ErbB2-mediated AKT/Nrf2 signaling. Thus, metformin may be a potential novel treatment approach for alcoholic cardiomyopathy.

Abstract
Di(2-ethylhexyl) phthalate (DEHP) is one of the most common organic pollutants and is added to various plastic products as a plasticizer. DEHP oxidative metabolite content in the human body is associated with DNA damage in sperm and decreased testosterone levels in blood. In this study, a DEHP-induced sperm DNA damage mouse model was replicated and improved, and the transcriptomic and proteomic characteristics of the model were observed. Male mice in the two groups were exposed to DEHP 1 g/kg/d or the same amount of normal saline for 60 days, and the sperm DNA fragmentation index (DFI) was detected by a sperm chromatin structure assay (SCSA). The mRNA and protein expression profiles of the testis were detected by RNA-seq and data-independent acquisition (DIA). The sperm DFI of the DEHP group was significantly increased. Compared with the control group, 111 differentially expressed genes (DEGs) and 2147 differentially expressed proteins (DEPs), such as Lamb2, Ahnak, Tkt, Dnah8 and Tbl2, were found in the DEHP group. These genes were mainly enriched in metabolic pathways, pathways in cancer and the PI3K-Akt signaling pathway. Our results showed that DEHP 1 g/kg/d can induce sperm DNA damage in a male mouse model after 60 days of intragastric administration. The reproductive toxicity of DEHP may be related to metabolic pathways in cancer and the PI3K-Akt signaling pathway.
