[PMID: 38452835 DOI: 10.1016/j.ejphar.2024.176482] [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: 11/15/2023] [Revised: 02/26/2024] [Accepted: 03/05/2024] [Indexed: 03/09/2024]
Abstract
Rotenone, a plant-based agricultural insecticide, has been shown to have anti-tumor activity through targeting mitochondrial complex I in cancer cells. However, off-target toxic side effect on nervous systems have greatly restricted the application of rotenone as anticancer drugs. Here, a folic acid-rotenol (FA-rotenol) conjugate was prepared by covalent coupling of the tumor-targeting ligand folic acid with rotenone derivative-rotenol to enhance its accumulation at tumor site. FA-rotenol conjugates present high in vitro cytotoxicties against several cell lines by inducing mitochondrial membrane potential depolarization and increasing the level of intracellular reactive oxygen species (ROS) to activate the mitochondrial pathway of apoptosis and enhance the G2/M cell cycle arrest. Because of the high affinity with over-expressed folate receptors, FA-rotenol conjugate demonstrated more effective in vivo therapeutic outcomes in 4T1 tumor-bearing mice than rotenone and rotenol. In addition, FA-rotenol conjugate can markedly inhibit the cell migration and invasion of HepG-2 cells. These studies confirm the feasibility of tumor-targeted ligand conjugated rotenone derivatives for targeted antitumor therapy; likewise, they lay the foundations for the development of other rotenol-conjugates with antitumor potential.

Shi B, Liu Q, Xu C, Zhang Z, Cai J. Chlorantraniliprole induces mitophagy, ferroptosis, and cytokine homeostasis imbalance in grass carp (Ctenopharyngodon idella) hepatocytes via the mtROS-mitochondrial fission/fusion axis. PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY 2024; 200:105830. [PMID: 38582593 DOI: 10.1016/j.pestbp.2024.105830] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Revised: 02/03/2024] [Accepted: 02/11/2024] [Indexed: 04/08/2024]
Abstract
Chlorantraniliprole (CAP) is a bis-amide pesticide used for pest control mainly in agricultural production activities and rice-fish co-culture systems. CAP residues cause liver damage in non-target organism freshwater fish. However, it is unclear whether CAP-exposure-induced liver injury in fish is associated with mitochondrial dysfunction-mediated mitophagy, ferroptosis, and cytokines. Therefore, we established grass carp hepatocyte models exposed to different concentrations of CAP (20, 40, and 80 μM) in vitro. MitoSOX probe, JC-1 staining, immunofluorescence double staining, Fe2+ staining, lipid peroxidation staining, qRT-PCR, and Western blot were used to verify the physiological regulatory mechanism of CAP induced liver injury. In the present study, the CAP-treated groups exhibited down-regulation of antioxidant-related enzyme activities and accumulation of peroxides. CAP treatment induced an increase in mitochondrial reactive oxygen species (mtROS) levels and altered expression of mitochondrial fission/fusion (Drp1, Fis1, Mfn1, Mfn2, and Opa1) genes in grass carp hepatocytes. In addition, mitophagy (Parkin, Pink1, p62, LC3II/I, and Beclin-1), ferroptosis (GPX4, COX2, ACSL4, FTH, and NCOA4), and cytokine (IFN-γ, IL-18, IL-17, IL-6, IL-10, IL-1β, IL-2, and TNF-α)-related gene expression was significantly altered. Collectively, these findings suggest that CAP exposure drives mitophagy activation, ferroptosis occurrence, and cytokine homeostasis imbalance in grass carp hepatocytes by triggering mitochondrial dysfunction mediated by the mtROS-mitochondrial fission/fusion axis. This study partly explained the physiological regulation mechanism of grass carp hepatocyte injury induced by insecticide CAP from the physiological and biochemical point of view and provided a basis for evaluating the safety of CAP environmental residues to non-target organisms.

Nigdelioglu Dolanbay S, Şirin S, Aslim B. Cocktail of three isoquinoline alkaloids derived from Glaucium grandiflorum Boiss. & A. Huet subsp. refractum (Nábelek) Mory inhibits the production of LPS-induced ROS, pro-inflammatory cytokines, and mediators through the down-regulation of p38 MAPK in BV-2 cells. Fitoterapia 2023; 170:105652. [PMID: 37595642 DOI: 10.1016/j.fitote.2023.105652] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 08/09/2023] [Accepted: 08/15/2023] [Indexed: 08/20/2023]
Abstract
Glaucium grandiflorum extracts have traditionally been used to treat brain-related disorders. G. grandiflorum extracts also exhibited inhibitory effects on cholinesterase enzymes, as well as antigenotoxic activity. However, no research has been done on the effect of G. grandiflorum alkaloid extracts on the anti-oxidative and anti-inflammatory mechanisms. In this study we aimed to evaluate the anti-oxidative and anti-inflammatory activities of the alkaloid extract obtained from G. grandiflorum as well as the mechanisms responsible for their neuroprotective effects in neuronal damage caused by LPS in BV2 cells. We used LC-MS/MS and 1H, 13C NMR analysis to determine the presence of major alkaloids (allocryptopine, tetrahydropalmatine, and tetrahydroberberine N-oxide (trans-cannadine-N-oxide) in the alkaloid extracts. We used flow cytometry to study the alkaloid extracts' effects on ROS production; we also employed qRT-PCR and Western Blot to analyze the effects of oxidative stress and inflammation-related genes and proteins. ROS production within the cell was inhibited by chloroform alkaloid extract (CAE). There occurred marked CAE-induced reductions in IL-1β, Cox-2, and iNOS mRNA expressions. We also observed marked reductions in IL-6 and TNF-α mRNA expressions with methanol alkaloid extract (MAE). CAE effectively suppressed IL-1β and iNOS protein levels, especially as in qRT-PCR studies, while MAE effectively reduced IL-6 and TNF-α protein levels. Additionally, MAE was found to be prominent in suppressing the levels of Cox-2 protein, unlike qRT-PCR studies. According to our study findings, oxidative stress brought about by inflammation was suppressed by alkaloid extracts from G. grandiflorum which can be attributed to their suppressor effects on the pro-inflammatory cytokines-mediators, and p38 MAPK. As a result, a drug active substance that suppresses oxidative stress and inflammation has been brought to the neuropharmacological field.

Abstract
To overcome the ethical and technical limitations of in vivo human disease models, the broader scientific community frequently employs model organism-derived cell lines to investigate disease mechanisms, pathways, and therapeutic strategies. Despite the widespread use of certain in vitro models, many still lack contemporary genomic analysis supporting their use as a proxy for the affected human cells and tissues. Consequently, it is imperative to determine how accurately and effectively any proposed biological surrogate may reflect the biological processes it is assumed to model. One such cellular surrogate of human disease is the established mouse neural precursor cell line, SN4741, which has been used to elucidate mechanisms of neurotoxicity in Parkinson disease for over 25 years. Here, we are using a combination of classic and contemporary genomic techniques - karyotyping, RT-qPCR, single cell RNA-seq, bulk RNA-seq, and ATAC-seq - to characterize the transcriptional landscape, chromatin landscape, and genomic architecture of this cell line, and evaluate its suitability as a proxy for midbrain dopaminergic neurons in the study of Parkinson disease. We find that SN4741 cells possess an unstable triploidy and consistently exhibits low expression of dopaminergic neuron markers across assays, even when the cell line is shifted to the non-permissive temperature that drives differentiation. The transcriptional signatures of SN4741 cells suggest that they are maintained in an undifferentiated state at the permissive temperature and differentiate into immature neurons at the non-permissive temperature; however, they may not be dopaminergic neuron precursors, as previously suggested. Additionally, the chromatin landscapes of SN4741 cells, in both the differentiated and undifferentiated states, are not concordant with the open chromatin profiles of ex vivo, mouse E15.5 forebrain- or midbrain-derived dopaminergic neurons. Overall, our data suggest that SN4741 cells may reflect early aspects of neuronal differentiation but are likely not a suitable proxy for dopaminergic neurons as previously thought. The implications of this study extend broadly, illuminating the need for robust biological and genomic rationale underpinning the use of in vitro models of molecular processes.

Abstract
Rotenone, a widely used pesticide, causes dopaminergic neurons loss and increase the risk of Parkinson's disease (PD). However, few studies link the role of PARP1 to neuroinflammatory response and autophagy dysfunction in rotenone-induced neurodegeneration. Here, we identified that PARP1 overactivation caused by rotenone led to autophagy dysfunction and NLRP3-mediated inflammation. Further results showed that PARP1 inhibition could reduce NLRP3-mediated inflammation, which was effectively eliminated by TFEB knockdown. Moreover, PARP1 poly(ADP-ribosyl)ated TFEB that reduced autophagy. Of note, PARP1 inhibition could rescue rotenone-induced dopaminergic neurons loss. Overall, our study revealed that PARP1 blocks autophagy through poly (ADP-ribosyl)ating TFEB and inhibited NLRP3 degradation, which suggests that intervention of PARP1-TFEB-NLRP3 signaling can be a new treatment strategy for rotenone-induced neurodegeneration.

Abstract
Neurodegenerative diseases (NDs) such as Alzheimer's disease, Parkinson's disease, and Huntington's disease are incurable diseases with progressive loss of neural function and require urgent development of effective treatments. Carnosol (CL) reportedly has a pharmacological effect in the prevention of dementia. Nevertheless, the mechanisms of CL's neuroprotection are not entirely clear. The present study aimed to investigate the effects and mechanisms of CL-mediated neuroprotection through Caenorhabditis elegans models. First, CL restored ND protein homeostasis via inhibiting the IIS pathway, regulating MAPK signaling, and simultaneously activating molecular chaperone, thus inhibiting amyloid peptide (Aβ), polyglutamine (polyQ), and α-synuclein (α-syn) deposition and reducing protein disruption-mediated behavioral and cognitive impairments as well as neuronal damages. Furthermore, CL could repair mitochondrial structural damage via improving the mitochondrial membrane protein function and mitochondrial structural homeostasis and improve mitochondrial functional defects via increasing adenosine triphosphate contents, mitochondrial membrane potential, and reactive oxygen species levels, suggesting that CL could improve the ubiquitous mitochondrial defects in NDs. More importantly, we found that CL activated mitochondrial kinetic homeostasis related genes to improve the mitochondrial homeostasis and dysfunction in NDs. Meanwhile, CL up-regulated unc-17, cho-1, and cha-1 genes to alleviate Aβ-mediated cholinergic neurological disorders and activated Notch signaling and the Wnt pathway to diminish polyQ- and α-syn-induced ASH neurons as well as dopaminergic neuron damages. Overall, our study clarified the beneficial anti-ND neuroprotective effects of CL in different aspects and provided new insights into developing CL into products with preventive and therapeutic effects on NDs.

Neurodegenerative diseases (NDs) are becoming a serious public health concern as the world’s population continues to age, demanding the discovery of more effective therapies. Excessive formation of reactive oxygen species (ROS) can result in oxidative stress (OS), which can be regarded as one of the common causes of neurodegenerative diseases (NDs). Thus, in this review, we focus on summarizing the consequences of ROS NDs, while taking the four prevalent NDs as examples, including Alzheimer’s disease (AD), Parkinson’s disease (PD), Amyotrophic lateral sclerosis (ALS), and Huntington’s disease (HD), to illustrate the key signaling pathways and relevant drugs. Together, these findings may shed new light on a field in which ROS-related pathways play a key role; thereby setting the groundwork for the future therapeutic development of neurodegenerative diseases.

Freshwater Clam Extract Mitigates Neuroinflammation and Amplifies Neurotrophic Activity of Glia: Insights from In Vitro Model of Neurodegenerative Pathomechanism. J Clin Med 2022; 11:jcm11030553. [PMID: 35160004 PMCID: PMC8836940 DOI: 10.3390/jcm11030553] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2021] [Revised: 01/16/2022] [Accepted: 01/20/2022] [Indexed: 11/28/2022] Open
Abstract
Background. An extensive body of research suggests that brain inflammation and oxidative stress are the underlying causes of Parkinson’s disease (PD), for which no potent therapeutic approach exists to mitigate the degradation of dopamine neurons. Freshwater clams, an ancient health food of Chinese origin, have been documented to exhibit anti-inflammatory and antioxidant effects. We previously reported that freshwater clam extract (FCE) can attenuate astrocytic activation and subsequent proinflammatory cytokine production from substantia nigra in an MPTP-induced PD mouse model. This article provides insight into the potential mechanisms through which FCE regulates neuroinflammation in a glia model of injury. Materials and methods. In total, 1 μg/mL lipopolysaccharide (LPS) and 200 μM rotenone were conducted in primary glial cell cultures to mimic the respective neuroinflammation and oxidative stress during injury-induced glial cell reactivation, which is relevant to the pathological process of PD. Results. FCE markedly reduced LPS-induced neuroinflammation by suppressing NO and TNF-α production and the expression of pro-inflammatory cytokines. In addition, FCE was effective at reducing rotenone-induced toxicity by diminishing ROS production, promoting antioxidant enzymes (SOD, catalase, and GPx) and minimizing the decline in glial-cell-secreted neurotrophic factors (GDNF, BDNF). These impacts ultimately led to a decrease in glial apoptosis. Conclusions. Evidence reveals that FCE is capable of stabilizing reactive glia, as demonstrated by reduced neuroinflammation, oxidative stress, the increased release of neurotrophic factors and the inhibition of apoptosis, which provides therapeutic insight into neurodegenerative diseases, including PD.
