Abstract
Exposure to toxicants/stressors has been linked to the development of many human diseases. They could affect various cellular components, such as DNA, proteins, lipids, and non-coding RNAs (ncRNA), thereby triggering various cellular pathways, particularly oxidative stress, inflammatory responses, and apoptosis, which can contribute to pathophysiological states. Accordingly, modulation of these pathways has been the focus of numerous investigations for managing related diseases. The involvement of various ncRNAs, such as small interfering RNA (siRNA), microRNAs (miRNA), and long non-coding RNAs (lncRNA), as well as various proteins and peptides in mediating these pathways, provides many target sites for pharmaceutical intervention. In this regard, various oligonucleotide- and protein/peptide-based therapies have been developed to treat toxicity-induced diseases, which have shown promising results in vitro and in vivo. This comprehensive review provides information about various aspects of toxicity-related diseases including their causing factors, main underlying mechanisms and intermediates, and their roles in pathophysiological states. Particularly, it highlights the principles and mechanisms of oligonucleotide- and protein/peptide-based therapies in the treatment of toxicity-related diseases. Furthermore, various issues of oligonucleotides and proteins/peptides for clinical usage and potential solutions are discussed.

ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2022; 305:119317. [PMID: 35439602 DOI: 10.1016/j.envpol.2022.119317] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 04/10/2022] [Accepted: 04/14/2022] [Indexed: 06/14/2023]
Abstract
Nonylphenol (NP) belongs to the metabolites of commercial detergents, which acts as an environmental endocrine disruptor. NP is reported to have multiple toxicity including reproductive toxicity. In present study, we reported the protective effects of melatonin on the NP-exposed oocyte quality. We set up a mouse in vivo model of NP exposure (500 μg/L), by daily drinking and continued feeding for 4 weeks; and we gave a daily dose of melatonin (30 mg/kg) to the NP-exposed mice. Melatonin supplementation restores the development ability of oocytes exposed to NP, and this was due to the reduction of ROS level and DNA damage by melatonin. Melatonin could rescue aberrant mitochondria distribution, mitochondria membrane potential, which also was reflected by ATP content and mtDNA copy number. Moreover, melatonin could restore the RPS3 expression to ensure the ribosome function for protein synthesis, and reduced GRP78 protein level to protect against ER stress and ER distribution defects. We also found that vesicle protein Rab11 from Golgi apparatus was protected by melatonin at the spindle periphery of oocytes of NP-exposed mice, which further moderated LAMP2 for lysosome function. Our results indicate that melatonin protects oocytes from NP exposure through its effects on the reduction of oxidative stress and DNA damage, which might be through its amelioration on the organelles in mice.

Abstract
OBJECTIVES Peptides and proteins represent great potential for modulating various cellular processes including oxidative stress, inflammatory response, apoptosis and consequently the treatment of related diseases. However, their therapeutic effects are limited by their inability to cross cellular barriers. Cell-penetrating peptides (CPPs), which can transport cargoes into the cell, could resolve this issue, as would be discussed in this review. KEY FINDINGS CPPs have been successfully exploited in vitro and in vivo for peptide/protein delivery to treat a wide range of diseases involving oxidative stress, inflammatory processes and apoptosis. Their in vivo applications are still limited due to some fundamental issues of CPPs, including nonspecificity, proteolytic instability, potential toxicity and immunogenicity. SUMMARY Totally, CPPs could potentially help to manage the diseases involving oxidative stress, inflammatory response and apoptosis by delivering peptides/proteins that could selectively reach proper intracellular targets. More studies to overcome related CPP limitations and confirm the efficacy and safety of this strategy are needed before their clinical usage.

Abstract
In mammalian cells, the bulky DNA adducts caused by ultraviolet radiation are mainly repaired via the nucleotide excision repair (NER) pathway; some defects in this pathway lead to a genetic disorder known as xeroderma pigmentosum (XP). Ribosomal protein S3 (rpS3), a constituent of the 40S ribosomal subunit, is a multi-functional protein with various extra-ribosomal functions, including a role in the cellular stress response and DNA repair-related activities. We report that rpS3 associates with transcription factor IIH (TFIIH) via an interaction with the xeroderma pigmentosum complementation group D (XPD) protein and complements its function in the NER pathway. For optimal repair of UV-induced duplex DNA lesions, the strong helicase activity of the TFIIH complex is required for unwinding damaged DNA around the lesion. Here, we show that XP-D cells overexpressing rpS3 showed markedly increased resistance to UV radiation through XPD and rpS3 interaction. Additionally, the knockdown of rpS3 caused reduced NER efficiency in HeLa cells and the overexpression of rpS3 partially restored helicase activity of the TFIIH complex of XP-D cells in vitro. We also present data suggesting that rpS3 is involved in post-excision processing in NER, assisting TFIIH in expediting the repair process by increasing its turnover rate when DNA is damaged. We propose that rpS3 is an accessory protein of the NER pathway and its recruitment to the repair machinery augments repair efficiency upon UV damage by enhancing XPD helicase function and increasing its turnover rate.

Abstract
Ultraviolet (UV) radiation is a major factor that causes wrinkle formation by affecting the collagen level in the skin. Here, we show that a short peptide (A8) derived from the repair domain of the ribosomal protein S3 (rpS3) reduces UV irradiation-induced increase in matrix metalloproteinase-1 (MMP-1) and prevents collagen degradation by reducing the activation of the mitogen-activated protein kinase (MAPK) signaling proteins (extracellular signal-regulated kinase [ERK], p38, and c-Jun N-terminal kinases [JNK]) and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) in cells. Furthermore, A8 also prevents the increase in the levels of inflammatory modulators such as tumor necrosis factor-alpha (TNF-α) or interleukin-6 (IL-6) in UV-irradiated cells. Collectively, our study suggests that the A8 peptide, derived from yeast or human, has anti-photoaging potential as it prevents UV-induced wrinkle formation.

Abstract
Ribosomal protein S3 (rpS3) has endonuclease activity for DNA repair. In particular, rpS3 cleaves the phosphodiester bonds of damaged DNA. In this study, we show that the repair domain of rpS3 spans amino acids 144-189. We fused rpS3 with the transactivator of transcription (TAT) sequence to introduce the rpS3 repair domain into cells. We find that the TAT-rpS3 (aa: 144-189) peptide cleaves UV-induced cyclobutane pyrimidine dimers (CPDs) in cells. We also reveal that the TAT-rpS3 peptide reduces matrix metalloproteinase-1 (MMP-1) induction in UV-irradiated fibroblasts and increases cell migration activity. Taken together, our study suggests that penetration of the rpS3 repair domain into cells can cleave UV-induced CPDs and reduce MMP-1 expression induced by UV.

Abstract
Different organisms, cell types, and even similar cell lines can dramatically differ in resistance to genotoxic stress. This testifies to the wide opportunities for genetic and epigenetic regulation of stress resistance. These opportunities could be used to increase the effectiveness of cancer therapy, develop new varieties of plants and animals, and search for new pharmacological targets to enhance human radioresistance, which can be used for manned deep space expeditions. Based on the comparison of transcriptomic studies in cancer cells, in this review, we propose that there is a high diversity of genetic mechanisms of development of genotoxic stress resistance. This review focused on possibilities and limitations of the regulation of the resistance of normal cells and whole organisms to genotoxic and oxidative stress by the overexpressing of stress-response genes. Moreover, the existing experimental data on the effect of such overexpression on the resistance of cells and organisms to various genotoxic agents has been analyzed and systematized. We suggest that the recent advances in the development of multiplex and highly customizable gene overexpression technology that utilizes the mutant Cas9 protein and the abundance of available data on gene functions and their signal networks open new opportunities for research in this field.

Abstract
Melanoma is one of the most aggressive and lethal cancers. Discovery and identification of novel therapeutic targets is urgently needed. In this study, we demonstrated that ribosomal protein S3 (RPS3) was a potential target involved in melanoma growth. Knockdown of RPS3 by siRNA suppressed cell growth and induced apoptosis in melanoma cells. Further mechanism studies showed that RPS3 knockdown in melanoma cells triggered the release of cytochrome C (Cyto C) from mitochondrial, increased the location of BID on mitochondrial membrane and the cleavage of the pro-apoptotic proteins (PARP, caspase-3 and -9), promoted the opening of mitochondrial permeability transition pore and the flooding of calcium ions (Ca(2+)) into the mitochondrial, and decreased the expression of the Ca(2+) gatekeeper MICU1 and its location on the mitochondrial. We also found that knockdown of RPS3 significantly inhibited tumor growth in a melanoma xenograft mouse model. Furthermore, we showed that RPS3 was highly expressed in melanoma cell lines and melanoma tumor tissues, and overexpression of RPS3 was associated with the poor prognosis of melanoma patients. Our results therefore demonstrate that RPS3 regulates melanoma growth through the modulation of the Cyto C/Ca(2+)/MICU1 dependent mitochondrial signaling and suggest that RPS3 is a potential therapeutic target for melanoma treatment.

Abstract
BACKGROUND Heme oxygenase-1 (HO-1) has been shown to have antioxidant and anti-apoptotic properties. The present study transduced HO-1 protein into intestinal tissues using PEP-1, a cell-penetrating peptide, and investigated its potentiality in prevention against intestinal ischemia/reperfusion (I/R) injury. MATERIALS AND METHODS PEP-1-HO-1 fusion protein was administered intravenously to explore the time and dose characteristics through measuring serum HO-1 levels. Twenty-four male Sprague-Dawley rats were randomly divided into three groups: sham, intestinal I/R (II/R), II/R + PEP-1-HO-1 fusion protein (HO). The model was established by occluding the superior mesenteric artery for 45 min followed by 120 min reperfusion. In HO group, PEP-1-HO-1 was administered intravenously 30 min before ischemia, whereas animals in sham and II/R groups received the equal volume of physiological saline. After the experiment, the intestines were harvested for determination of histologic injury, wet/dry ratio, enzyme activity, apoptosis, and His-probe protein (one part of PEP-1-HO-1). RESULTS Levels of serum HO-1 were dose- and time-dependent manner after intravenous injection of PEP-1-HO-1. I/R caused deterioration of histologic characteristics and increases in histologic injury scoring, wet/dry ratio, myeloperoxidase activity, malondialdehyde, and intestinal apoptosis. These changes were also accompanied by a decrease in superoxide dismutase activity (P < 0.05). PEP-1-HO-1 treatment significantly reversed these changes (P < 0.05). Furthermore, His-probe protein expression was only detected in PEP-1-HO-1-treated animals. CONCLUSION Treatment of PEP-1-HO-1 attenuates intestinal I/R injury, which might be attributable to its antioxidant and anti-apoptotic roles of HO-1.

Abstract
Parkinson's disease (PD) is a neurodegenerative disease characterized by a gradual loss of dopaminergic (DA) neurons in the substantia nigra (SN) of the brain. Ribosomal protein S3 (rpS3) has multiple functions related to protein synthesis, antioxidative activity, and UV endonuclease III activity. We have previously shown that PEP-1-rpS3 inhibits skin inflammation and provides neuroprotection against experimental cerebral ischemic damage. In this study, we examined whether PEP-1-rpS3 can protect DA neurons against oxidative stress in SH-SY5Y neuroblastoma cells and in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD mouse model. PEP-1-rpS3 was efficiently delivered to SH-SY5Y cells and the SN of the brain as confirmed by Western blot and immunohistochemical analysis. PEP-1-rpS3 significantly inhibited reactive oxygen species generation and DNA fragmentation induced by 1-methyl-4-phenylpyridinium, consequently leading to the survival of SH-SY5Y cells. The neuroprotection was related to the antiapoptotic activity of PEP-1-rpS3 that affected the levels of proapoptotic and antiapoptotic mediators. In addition, immunohistochemical data collected using a tyrosine hydroxylase antibody and cresyl violet staining demonstrated that PEP-1-rpS3 markedly protected DA cells in the SN against MPTP-induced oxidative stress. Therefore, our results suggest that PEP-1-rpS3 may be a potential therapy for PD.

Abstract
Parkinson's disease (PD) is caused by various factors such as reactive oxygen species (ROS), dysfunction of mitochondria, and aggregation of misfolded proteins, thereby leading to loss of dopaminergic (DA) neurons in the substantia nigra (SN) of the brain. Frataxin (FXN) is associated with iron homeostasis and biogenesis of iron-sulfur clusters in the electron transport chain complex. In this study, we investigated the potential of Tat-FXN to cross the blood-brain barrier (BBB) and protect DA neurons against oxidative stress in a mouse model of PD. Tat-FXN was effectively transduced into SH-SY5Y cells and blocked production of ROS and cleavage of DNA, significantly improving cell survival against 1-methyl-4-phenylpyridinium induced toxicity. In addition, Tat-FXN efficiently penetrated the BBB and exhibited a clear neuroprotective effect on tyrosine hydroxylase-specific DA neurons in the SN in a mice model of 1-methyl-4-phenyl-1,2,3,6-tetra-hydropyridine-induced PD. Therefore, these results suggest that Tat-FXN may provide neuroprotective therapy for ROS related diseases including PD.

Abstract
Parkinson's disease (PD) is a well known neurodegenerative disorder characterized by selective loss of dopaminergic neurons in the substantia nigra pars compact (SN). Although the exact mechanism remains unclear, oxidative stress plays a critical role in the pathogenesis of PD. DJ-1 is a multifunctional protein, a potent antioxidant and chaperone, the loss of function of which is linked to the autosomal recessive early onset of PD. Therefore, we investigated the protective effects of DJ-1 protein against SH-SY5Y cells and in a PD mouse model using a cell permeable Tat-DJ-1 protein. Tat-DJ-1 protein rapidly transduced into the cells and showed a protective effect on 6-hydroxydopamine (6-OHDA)-induced neuronal cell death by reducing the reactive oxygen species (ROS). In addition, we found that Tat-DJ-1 protein protects against dopaminergic neuronal cell death in 1-methyl-4-phenyl-1,2,3,6,-tetrahydropyridine (MPTP)-induced PD mouse models. These results suggest that Tat-DJ-1 protein provides a potential therapeutic strategy for against ROS related human diseases including PD.

Abstract
Chlorogenic acid (CGA) possesses various biological activities such as anti-oxidant, anti-inflammatory, and anti-diabetic activities. In the present study, we examined the effect of CGA on the transduction efficiency of PEP-1-ribosomal protein S3 (PEP-1-rpS3) into cells and brain tissues, and its neuroprotective potential against ischemia/reperfusion. We found that, in the presence of CGA, the transduction efficiency of PEP-1-rpS3 into astrocytes and the CA1 region of the hippocampus was enhanced, compared to its transduction in the absence of CGA. Also, cell viability data demonstrated that the sample treated with CGA + PEP-1-rpS3 exhibited improved cell viability against hydrogen peroxide (H2O2)-induced toxicity more significantly than the sample treated with PEP-1-rpS3 alone. Also, in a gerbil ischemia model, data demonstrated that following the ischemic insult, the group treated with PEP-1-rpS3 + CGA showed markedly enhanced protection of neuron cells in CA1 region of hippocampus, compared to those treated with CGA or PEP-1-rpS3 alone. Taken together, these results suggest that CGA may improve the transduction efficiency of protein transduction domain (PTD) fusion proteins into target cells or tissues, thereby enhancing their therapeutic potential against various diseases.

Abstract
The low transduction efficiency of various proteins is an obstacle to their therapeutic application. However, protein transduction domains (PTDs) are well-known for a highly effective tool for exogenous protein delivery to cells. We examined the effects of pergolide mesylate (PM) on the transduction of PEP-1-catalase into HaCaT human keratinocytes and mice skin and on the anti-inflammatory activity of PEP-1-catatase against 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammation using Western blot and histological analysis. PM enhanced the time- and dose-dependent transduction of PEP-1-catalase into HaCaT cells without affecting the cellular toxicity. In a mouse edema model, PEP-1-catalase inhibited the increased expressions of inflammatory mediators and cytokines such as cyclooxygenase-2, inducible nitric oxide synthase, interleukin-6 and -1β, and tumor necrosis factor-α induced by TPA. On the other hand, PM alone failed to exert any significant anti-inflammatory effects. However, the anti-inflammatory effect of co-treatment with PEP-1-catalase and PM was more potent than that of PEP-1-catalase alone. Our results indicate that PM may enhance the delivery of PTDs fusion therapeutic proteins to target cells and tissues and has potential to increase their therapeutic effects of such drugs against various diseases.

Abstract
Reactive oxygen species (ROS) actively contribute to the development of a number of human diseases including ischemia. In response to oxidative stress, frataxin has a significant ability to improve cell survival though its biological function is unclear in relation to ischemia. To explore frataxin's role in protecting against ischemic cell death, we constructed PEP-1-Frataxin cell-permeable fusion protein. In a dose- and time-dependent manner PEP-1-Frataxin rapidly transduced into astrocyte cells and protected them against oxidative stress-induced cell death. Further, using an animal model, immunohistochemical analysis revealed that PEP-1-Frataxin prevented neuronal cell death in the CA1 region of the hippocampus induced by transient forebrain ischemia. These results demonstrate that transduced PEP-1-Frataxin protects against cell death in vitro and in vivo, suggesting that transduction of PEP-1-Frataxin could be useful as a therapeutic agent for various human diseases related to oxidative stress.

Abstract
Inward rectifying potassium (Kir) channels participate in regulating potassium concentration (K(+)) in the central nervous system (CNS), including in the retina. We explored the contribution of Kir channels to retinal function by delivering Kir antibodies (Kir-Abs) into the rat eye in vivo to interrupt channel activity. Kir-Abs were coupled to a peptide carrier to reach intracellular epitopes. Functional effects were evaluated by recording the scotopic threshold response (STR) and photopic negative response (PhNR) of the electroretinogram (ERG) noninvasively with an electrode on the cornea to determine activity of the rod and cone pathways, respectively. Intravitreal delivery of Kir2.1-Ab coupled to the peptide carrier diminished these ERG responses equivalent to dimming the stimulus 10- to 100-fold. Immunohistochemistry (IHC) showed Kir2.1 immunostaining of retinal bipolar cells (BCs) matching the labeling pattern obtained with conventional IHC of applying Kir2.1-Ab to fixed retinal sections postmortem. Whole-cell voltage-clamp BC recordings in rat acute retinal slices showed suppression of barium-sensitive Kir2.1 currents upon inclusion of Kir2.1-Ab in the patch pipette. The in vivo functional and structural results implicate a contribution of Kir2.1 channel activity in these electronegative ERG potentials. Studies with Kir4.1-Ab administered in vivo also suppressed the ERG components and showed immunostaining of Müller cells. The strategy of administering Kir antibodies in vivo, coupled to a peptide carrier to facilitate intracellular delivery, identifies roles for Kir2.1 and Kir4.1 in ERG components arising in the proximal retina and suggests this approach could be of further value in research.

Abstract
The transcription factor nuclear factor (NF)-κB is known to modulate rates of apoptosis and may therefore play a role in the increased β-cell death that occurs in type 1 and type 2 diabetes. The aim of the present investigation was to study the expression of NF-κB subunits in human islet cells and whether overexpression of the NF-κB subunit c-Rel affects islet cell survival. We detected expression of p65, Rel-B, p50, p105, p52, and the ribosomal protein S3 (rpS3) in human islet cells. Among these, only p65 and rpS3 were translocated from the cytosolic to the nuclear fraction in response to cytokines. Interestingly, rpS3 participated in p65 binding to the κB-element in gel shift analysis experiments. We observed cytoplasmic c-Rel expression in vivo in 6J mice, and signs of nuclear translocation in β-cells of infiltrated nonobese diabetic islets. Human islet cells were also dispersed by trypsin treatment and transduced with a c-Rel adenoviral vector. This resulted in increased expression of c-Rel and inhibitory factor κB, increased κB-binding activity, and augmented protein levels of Bcl-X(L,) c-IAP2, and heat shock protein 72. c-Rel expression in human islet cells protected against cytokine-induced caspase 3 activation and cell death. c-Rel protected also against streptozotocin- and H(2)O(2)-induced cell death, in both intact rat islets and human islet cells. We conclude that rpS3 participates in NF-κB signaling and that a genetic increase in the activity of the NF-κB subunit c-Rel results in protection against cell death in human islets.

Abstract
Antioxidant enzymes are considered to have beneficial effects against various diseases mediated by reactive oxygen species (ROS). Ischemia is characterized by both oxidative stress and changes in the antioxidant defense system. Catalase (CAT) and superoxide dismutase (SOD) are major antioxidant enzymes by which cells counteract the deleterious effects of ROS. To investigate the protective effects of CAT, we constructed PEP-1-CAT cell-permeative expression vectors. When PEP-1-CAT fusion proteins were added to the culture medium of neuronal cells, they rapidly entered the cells and protected them against oxidative stress-induced neuronal cell death. Immunohistochemical analysis revealed that PEP-1-CAT prevented neuronal cell death in the hippocampus induced by transient forebrain ischemia. Moreover, we showed that the protective effect of PEP-1-CAT was observed in neuronal cells treated with PEP-1-SOD. Therefore, we suggest that transduced PEP-1-CAT and PEP-1-SOD fusion proteins could be useful as therapeutic agents for various human diseases related to oxidative stress, including stroke.

Abstract
Direct protein transfection is a potentially valuable tool for studying protein function in basic and clinical research. A major challenge is to enable a sufficiently large amount of protein to penetrate the plasma membrane of the transfected cells. Pep-1, a protein transfection reagent, was evaluated for its ability and efficiency in delivering proteins and antibodies into mouse Müller cells in vitro and in vivo. Pep-1 delivered active beta-galactosidase enzyme and antibodies (non-specific IgG and Cy3-conjugated anti-vimentin) into cultured Müller cells with high efficiency. Transfection efficiency increased with increasing concentration of the protein in the complex and with incubation time. Following intravitreal injection of Pep-1/IgG complexes in vivo, retinal histology was preserved and immunostaining showed that the antibodies were distributed widely across the retinal surface, with the most intense staining located near the retino-vitreal border. For complexes using non-specific IgG, double staining with anti-glutamine synthetase identified many IgG-positive cells as Müller glia. IgG immunoreactivity was also detected in the cytoplasm and occasionally in the nuclei of inner retinal neurons. Dark-adapted flash electroretinogram (ERG) recordings from injected eyes were nearly identical to ERG recordings from control eyes, suggesting that injection of Pep-1/IgG complex has minimal effects on retinal function. Therefore, Pep-1 is a useful tool for intracellular delivery of antibodies to study the role of proteins in living cells.
