The roles of MicroRNAs in cadmium toxicity and in the protection offered by plant food-derived dietary phenolic bioactive substances against cadmium-induced toxicity. Food Chem 2024; 460:140483. [PMID: 39032304 DOI: 10.1016/j.foodchem.2024.140483] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 07/11/2024] [Accepted: 07/14/2024] [Indexed: 07/23/2024]
Abstract
Cadmium, a harmful food contaminant, poses severe health risks. There are ongoing efforts to reduce cadmium pollution and alleviate its toxicity, including plant-based dietary intervention. This review hypothesizes that microRNAs (miRNAs), as regulatory eukaryotic transcripts, play crucial roles in modulating cadmium-induced organ damage, and plant food-derived bioactive compounds provide protective effects via miRNA-mediated mechanisms. The review reveals that there are interplays between certain miRNAs and plant food-derived dietary bioactive substances when these bioactives, especially phenolics, counteract cadmium toxicity through regulating physiologic and pathologic events (including oxidative stress, apoptosis, autophagy and inflammation). The review discusses common miRNA-associated physiologic/pathologic events and signal pathways shared by the cadmium toxicity and dietary intervention processes. This paper identifies the existing knowledge gaps and potential future work (e.g. joint actions between miRNAs and other noncoding RNAs in the fights against cadmium). The insights provided by this review can improve food safety strategies and public health outcomes.

Yuan B, Mao J, Wang J, Luo S, Luo B. Naringenin mitigates cadmium-induced cell death, oxidative stress, mitochondrial dysfunction, and inflammation in KGN cells by regulating the expression of sirtuin-1. Drug Chem Toxicol 2024; 47:445-456. [PMID: 38647073 DOI: 10.1080/01480545.2023.2288798] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Accepted: 11/05/2023] [Indexed: 04/25/2024]
Abstract
The objective of this study was to examine the potential protective role of naringenin against the harmful effects induced by cadmium in KGN cell line. Cell viability was evaluated by cell counting kit-8 assay. Caspase-3/-9 activities were determined by caspase-3/-9 activity assay kits, respectively. Intracellular reactive oxygen species (ROS) level was detected by ROS-Glo™ H2O2 Assay, antioxidant capacity was determined by a total antioxidant capacity assay kit. Mitochondrial membrane potential (MMP), ATP level, and ATP synthase activity were determined by JC-1, ATP assay kit, and ATP synthase activity assay kit, respectively. The mRNA expression was determined by qRT-PCR. Cadmium reduced cell viability and increased caspase-3/-9 activities in a concentration-dependent manner. Naringenin improved cell viability and reduced caspase-3/-9 activities in cadmium-stimulated KGN cells in a concentration-dependent manner. Cadmium diminished the antioxidant capacity, increased ROS production, and induced mitochondrial dysfunction in KGN cells. These effects were ameliorated by naringenin treatment in a concentration-dependent manner. Furthermore, naringenin reduced the levels of pro-inflammatory cytokines in KGN cells exposed to cadmium. SIRT1 knockdown downregulated its expression in KGN cells and compromised the protective effects of naringenin on cell viability and caspase-3/-9 activities in cadmium-stimulated KGN cells. Naringenin prevented the reduction of MMP, ATP levels, and ATP synthase activity in cadmium-stimulated KGN cells in a concentration-dependent manner. However, these protective effects were significantly reversed by SIRT1 knockdown. In conclusion, this study suggests that naringenin protects against cadmium-induced damage by regulating oxidative stress, mitochondrial function, and inflammation in KGN cells, with SIRT1 playing a potential mediating role.

Theriogenology 2024; 216:12-19. [PMID: 38147714 DOI: 10.1016/j.theriogenology.2023.11.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 11/29/2023] [Accepted: 11/29/2023] [Indexed: 12/28/2023]
Abstract
Although somatic cell nuclear transfer (SCNT) is a critical component of animal cloning, this approach has several issues. We previously introduced the cytoplasm injection cloning technology (CICT), which significantly improves the quality and quantity of cloned embryos. This study examined the residual status of fused cytoplasmic organelles, such as the endoplasmic reticulum (ER) and lysosomes, in the CICT group during early embryo development. We found that extra-cytoplasmic organelles stained using the ER-Tracker™ Green dye and LysoTracker™ Deep Red probe were fused and dispersed throughout the recipient oocyte and were still visible in day 8 blastocysts. We screened for ER stress, autophagy, and apoptosis-related genes to elucidate the association between the added organelles and improved embryo quality in CICT-cloned embryos. We found that CHOP, ATF4, ATG5, ATG7, and LC3 genes showed non-significantly up- or downregulated expression between CICT- and in vitro fertilization (IVF)-derived embryos but showed significantly (p < 0.05) upregulated expression in SCNT-cloned embryos. Surprisingly, a non-significant difference in the expression of some genes, such as ATF6 and caspase-3, was observed between the CICT- and SCNT-cloned embryos. Our findings imply that compared to conventional SCNT cloning, CICT-derived cloned embryos with additional cytoplasm have much higher organelle activity, lower autophagy, lower rates of apoptosis, and higher embryo development rates.

Abstract
Dynamic epigenetic regulation is critical for proper oogenesis and early embryo development. During oogenesis, fully grown germinal vesicle oocytes develop to mature Metaphase II oocytes which are ready for fertilization. Fertilized oocyte proliferates mitotically until blastocyst formation and the process is called early embryo development. Throughout oogenesis and early embryo development, spatio-temporal gene expression takes place, and this dynamic gene expression is controlled with the aid of epigenetics. Epigenetic means that gene expression can be altered without changing DNA itself. Epigenome is regulated through DNA methylation and histone modifications. While DNA methylation generally ends up with repression of gene expression, histone modifications can result in expression or repression depending on type of modification, type of histone protein and its specific residue. One of the modifications is histone acetylation which generally ends up with gene expression. Histone acetylation occurs through the addition of acetyl group onto amino terminal of the core histone proteins by histone acetyltransferases (HATs). Contrarily, histone deacetylation is associated with repression of gene expression, and it is catalyzed by histone deacetylases (HDACs). This review article focuses on what is known about alterations in the expression of HATs and HDACs and emphasizes importance of HATs and HDACs during oogenesis and early embryo development.

Abstract
Exposure to reactive oxygen species (ROS) leads to the oxidation of low-density lipoproteins (LDL), converting them into oxidized ones (oxLDL), which are involved in the pathogenesis of Alzheimer's disease, suggesting a potential link between lipid dysregulation and neurodegenerative processes. Phenolic metabolites derived from Artocarpus elasticus root bark were found to possess significant antioxidant properties at three different radical scavenging assays, including 2,2-diphenyl-1-picrylhydrazyl (DPPH), oxygen radical absorbance capacity (ORAC), and thiobarbituric acid reactive substances (TBARS). Among them, furanodihydrobenzoxanthones (1-3) demonstrated notable protection against Cu2+ induced LDL oxidation, with IC50 values ranging from 0.9 to 2.9 μM in measurement of the malondialdehyde (MDA) production at TBARS and prolonged lag times (>180 min) in the generation of conjugated diene (CD). At a concentration of 10 μM, all three compounds (1-3) effectively protected against LDL oxidation as determined by relative electrophoretic mobility (REM). The most potent compound 1 defended human neuroblastoma SH-SY5Y cells from oxLDL-mediated dysfunction, including oxLDL-induced cytotoxicity, inhibited reactive oxygen species (ROS) formation, and enhancing mitochondrial membrane potential (ΔΨm). Individual components annotation in the ethylacetate extract was performed using LC-ESI-QTOF/MS, which serves as a chemotaxonomic marker for A. elasticus root barks.

Mech Ageing Dev 2023; 209:111756.

Abstract
Age-related deterioration in the reproductive capacity of women is directly related to the poor developmental potential of ovarian follicles. Although telomerase plays a key role in female fertility, TERT-targeting therapeutic strategies for age-related female infertility have yet to be investigated. This study elucidated the effect of Telomerase activation on mice ovaries and more specifically on Klb (β-Klotho) gene expression, which is linked to ageing, female hormonal regulation, and cyclicity. The homology-based 3D model of hTERT was used to predict its binding mode of Cycloastragenol (CAG) using molecular docking and molecular dynamics simulations. Based on docking score, simulation behavior, and interaction with hTERT residues it was observed that CAG could bind with the hTERT model. CAG treatment to primary cultured mouse granulosa cells and activation of telomerase was examined via telomerase activity assay (Mouse TE (telomerase) ELISA Kit) and telomere length by quantitative fluorescence in situ hybridization. CAG mediated telomerase also significantly improved β-Klotho protein level in the aged granulosa cells. To demonstrate that β-Klotho is telomerase dependent, the TERT was knocked down via siRNA in granulosa cells and protein level of β-Klotho was examined. Furthermore, CAG-mediated telomerase activation significantly enhanced the level of Klb and recovered ovarian follicles in the D-galactose (D-gal)-induced ovarian ageing mouse model. Moreover, Doxorubicin-induced ovarian damage, which changes ovarian hormones, and inhibit follicular growth was successfully neutralized by CAG activated telomerase and its recovery of β-Klotho level. In conclusion, TERT dependent β-Klotho regulation in ovarian tissues is one of the mechanisms, which can overcome female infertility.

Abstract
Recent investigations have revealed that puerarin (PU) alleviates cadmium (Cd)-caused hepatic damage via inhibiting oxidative stress. Mitochondria are dynamic organelles and play a critical part in regulating the occurrence of oxidative stress, but the role of mitochondria in the protection of PU against hepatocellular damage caused by Cd exposure remains unknown. Thus, this study was aimed to clarify this issue using mouse hepatocyte AML-12 cell line. Transmission electron microscopy analysis firstly showed that PU prevents Cd-induced mitochondrial ultrastructure damage. Mitochondrial network image analysis by confocal microscopy revealed that PU exerts the protection against Cd-induced cytotoxicity via restoring mitochondrial network fragmentation. Also, mitochondrial dynamic protein expression profiles showed that enhanced fission protein levels and inhibited fusion protein levels in Cd-treated cells were significantly reversed by PU, suggesting the protective effect of PU against Cd-induced mitochondrial fission. Moreover, changes of intracellular ATP level and protein levels of key regulators involving in mitochondrial biogenesis indicated that Sirtuin-1(Sirt1) pathway may be involved in the protection of Cd-impaired mitochondrial function by PU. Next, Sirt1 protein levels in treated cells were effectively regulated by genetic knockdown or chemical agonist SRT1720. Accordingly, alleviation of Cd-induced mitochondrial fission assays and cell viability by PU was markedly regulated by SRT1720 or Sirt1 knockdown, suggesting the indispensable role of Sirt1 in this process. Collectively, these findings highlight that PU prevents Cd-induced mitochondrial fission to alleviate cytotoxicity via Sirt1-dependent pathway, which provide novel evidences to fully understand the hepatoprotective action of PU against heavy metal toxicity.
