The protective role of Cordyceps cicadae and its active ingredient myriocin against sodium iodate-induced age-related macular degeneration via an anti-necroptotic TNF-RIPK1/3 pathway. JOURNAL OF ETHNOPHARMACOLOGY 2024; 334:118565. [PMID: 39002821 DOI: 10.1016/j.jep.2024.118565] [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: 04/23/2024] [Revised: 06/05/2024] [Accepted: 07/09/2024] [Indexed: 07/15/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cordyceps cicadae (C.cicadae), named "Chan Hua", an anamorph of Isaria cicadae Miquel, is an entomogenous complex formed by fungi parasitizing on the larvae of cicadas and belongs to the Claviciptaceae family and the genus Codyceps, which traditionally holds a significant place in Chinese ethnopharmacology, specifically for eye clarity and as a remedy for age-related ocular conditions. The underlying mechanisms contributing to its eyesight enhancement and potential effectiveness against Age-related macular degeneration (AMD) remain unexplored. AIM OF THE STUDY This study aims to elucidate the protective role of C.cicadae and its active ingredient, Myriocin (Myr), against AMD. MATERIALS AND METHODS A chemical inducer was employed to make retinal pigment epithelium (RPE) damage in vitro and in vivo. The key ingredients of C.cicadae and their related mechanisms for anti-AMD were studied through bioinformatic analysis and molecular biological approaches. RESULTS Myr was identified through high-performance liquid chromatography (HPLC) as an active ingredient in C.cicadae, and demonstrated a protective effect on RPE cells, reducing the structural damage and cell death induced by sodium iodate (SI). Further, Myr reduced eyelid secretions in AMD mice and restored their retinal structure and function. The differentially expressed genes (DEGs) in Myr treatment are primarily associated with TNF and Necroptosis signaling pathways. Molecular docking indicated a strong affinity between TNF and Myr. Myr inhibited the TNF signaling pathway thereby reducing the expression of inflammatory factors in ARPE-19 cells. Additionally, Myr had consistent action with the necroptosis inhibitor Necrostatin-1 (Nec-1), inhibited the RIPK1/RIPK3/MLKL pathway thereby protecting ARPE-19 cells. CONCLUSION The findings present Myr, as a potent protector against SI-induced AMD, predominantly through modulation of the TNF-RIPK1/RIPK3/MLKL signaling pathway, offering the insights of therapeutic C.cicadae as viable candidates for AMD treatment.

J Cell Biol 2024; 223:e202305026. [PMID: 38319288 PMCID: PMC10847335 DOI: 10.1083/jcb.202305026] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 10/23/2023] [Accepted: 12/15/2023] [Indexed: 02/07/2024] Open
Abstract
TNFα and IFNγ (TNF/IFNγ) synergistically induce caspase-8 activation and cancer cell death. However, the mechanism of IFNγ in promoting TNF-initiated caspase-8 activation in cancer cells is poorly understood. Here, we found that in addition to CASP8, CYLD is transcriptionally upregulated by IFNγ-induced transcription factor IRF1. IRF1-mediated CASP8 and CYLD upregulation additively mediates TNF/IFNγ-induced cancer cell death. Clinically, the expression levels of TNF, IFNγ, CYLD, and CASP8 in melanoma tumors are increased in patients responsive to immune checkpoint blockade (ICB) therapy after anti-PD-1 treatment. Accordingly, our genetic screen revealed that ELAVL1 (HuR) is required for TNF/IFNγ-induced caspase-8 activation. Mechanistically, ELAVL1 binds CASP8 mRNA and extends its stability to sustain caspase-8 expression both in IFNγ-stimulated and in basal conditions. Consequently, ELAVL1 determines death receptors-initiated caspase-8-dependent cell death triggered from stimuli including TNF and TRAIL by regulating basal/stimulated caspase-8 levels. As caspase-8 is a master regulator in cell death and inflammation, these results provide valuable clues for tumor immunotherapy and inflammatory diseases.

Abstract
The process of ubiquitination and deubiquitination is widely present in the human body's protein reactions and plays versatile roles in multiple diseases. Deubiquitinating enzymes (DUBs) are significant regulators of this process, which cleave the ubiquitin (Ub) moiety from various substrates and maintain protein stability. Lung adenocarcinoma (LUAD) is the most common type of non-small cell lung cancer (NSCLC) and remains refractory to treatment. To elucidate the mechanism of LUAD and advance new therapeutic targets, we review the latest research progress on DUBs in LUAD. We summarize the biological capabilities of these DUBs and further highlight those DUBs that may serve as anticancer target candidates for precision treatment. We also discuss deubiquitinase inhibitors, which are expected to play a role in targeted LUAD therapy.

Abstract
The tumor microenvironment (TME) is an intricate system within solid neoplasms. In this review, we aim to provide an updated insight into the TME with a focus on the effects of tumor necrosis factor-α (TNF-α) on its various components and the use of TNF-α to improve the efficiency of drug delivery. The TME comprises the supporting structure of the tumor, such as its extracellular matrix and vasculature. In addition to cancer cells and cancer stem cells, the TME contains various other cell types, including pericytes, tumor-associated fibroblasts, smooth muscle cells, and immune cells. These cells produce signaling molecules such as growth factors, cytokines, hormones, and extracellular matrix proteins. This review summarizes the intricate balance between pro-oncogenic and tumor-suppressive functions that various non-tumor cells within the TME exert. We focused on the interaction between tumor cells and immune cells in the TME that plays an essential role in regulating the immune response, tumorigenesis, invasion, and metastasis. The multifunctional cytokine, TNF-α, plays essential roles in diverse cellular events within the TME. The uses of TNF-α in cancer treatment and to facilitate cancer drug delivery are discussed. The effects of TNF-α on tumor neovasculature and tumor interstitial fluid pressure that improve treatment efficacy are summarized.

Abstract
INTRODUCTION Chemotherapeutic resistance reduces the sensitivity of bladder urothelial carcinoma (BUC) to chemotherapeutic drugs and contributes a barrier leading to treatment failure. The purpose of this research project is to investigate the regulatory effects of miR-130b on chemotherapeutic drug resistance of BUC and its mechanism. MATERIAL AND METHODS The relative expression of miRNA-130b and cylindromatosis (CYLD) was examined using real-time quantitative PCR. The cell proliferation and doxorubicin sensitivity were detected with the enhanced CCK-8 assay. The specific combination of miR-130b and CYLD was verified with the luciferase reporter gene assay. Protein expression was detected by Western blot. RESULTS Our study found that miR-130b was up-regulated in doxorubicin-insensitive BUC tissues and cell lines, and its high expression was negatively related to doxorubicin sensitivity in BUC. The miR-130b knockdown reduced the IC50 of doxorubicin and improved doxorubicin sensitivity of J82/Dox and T24/Dox cells. For the regulation mechanism analysis of miR-130b, bioinformatics analysis software was used to predict the potential targets of miR-130b, including the CYLD gene. The following luciferase activities assay, quantitative real time-PCR and western blot identified the CYLD gene as a target of miR-130b. Knockdown of CYLD reversed miR-130b's regulatory roles in doxorubicin sensitivity in J82/Dox and T24/Dox cells. CONCLUSIONS High expression of miR-130b is negatively related to doxorubicin sensitivity in BUC, and knockdown of miR-130b improves doxorubicin sensitivity in BUC by negatively regulating CYLD expression. Our findings will provide guidance for the clinical chemotherapy of BUC.

Abstract
Lung cancer, renowned for its fast progression and metastatic potency, is rising to become a leading cause of death globally. It has been long observed that lung cancer is particularly ept in spawning distant metastasis at its early stages, and it can readily colonize virtually any human organ. In recent years, cancer research has shed light on why lung cancer is endowed with its exceptional ability to metastasize. In this review, we will take a comprehensive look at the current research on lung cancer metastasis, including molecular pathways, anatomical features and genetic traits that make lung cancer intrinsically metastatic, as we go from lung cancer’s general metastatic potential to the particular metastasis mechanisms in multiple organs. We highly concerned about the advanced discovery and development of lung cancer metastasis, indicating the importance of lung cancer specific gene mutations, heterogeneity or biomarker discovery, and discussing potential opportunities and challenges. We will also introduce some current treatments that targets certain metastatic strategies of non-small cell lung cancer (NSCLC). Advances made in these regards could be critical to our current knowledge base of lung cancer metastasis.

Abstract
Purpose Nasopharyngeal carcinoma (NPC) is among the most common malignancies derived from the epithelium of the nasopharynx. To date, the regulatory networks involved in NPC have not been fully identified. Previous studies revealed multiple loss-of-function mutations in NPC and specifically in cylindromatosis lysine 63 deubiquitinase (CYLD); however, the exact role of CYLD in NPC progression and its potential mechanism remains unclear. Methods We performed immunohistochemical (IHC) staining and real-time quantitative polymerase chain reaction (qPCR) to measure CYLD expression in NPC tissues, and Western blot was conducted to determine CYLD levels in NPC cell lines. Cell proliferation was detected by CCK8 assay and colony formation analysis, and apoptosis was determined by Annexin V/propidium iodide staining. Potential targets of CYLD were verified by co-immunoprecipitation and mass spectrometry. Xenograft assay was conducted to confirm the role of CYLD in vivo. Results We found that CYLD levels were significantly decreased in both NPC tissues and cell lines, and that CYLD overexpression inhibited NPC cell proliferation and promoted apoptosis. Additionally, we revealed that CYLD bound and upregulated N-Myc downstream regulated 1 (NDRG1), and that silencing NDRG1 abolished the tumor-suppressor effect of CYLD on NPC cells. Furthermore, CYLD suppressed tumor growth in xenograft mice models. Conclusion These results suggest CYLD as a tumor suppressor, potential biomarker for diagnosing NPC, and therapeutic target.

Abstract
OBJECTIVE To assess the changes in the effects of cantharides after alkaline processing on proliferation, migration, invasion, and apoptosis of human lung cancer A549 cells. METHODS Human non-small cell lung cancer A549 cells were treated with cantharis extract (CTE) from raw cantharides and alkali processed cantharis extract (ACE). The proliferation of the cells was detected with CCK-8 assay, and the cell migration and invasion were assessed using wound healing assay and Transwell assay, respectively. The expressions of MMP1 and MMP2 in the cells were detected using Western blotting, the contents of IFN-γ, IL-1β and TNF-α were measured with ELISA, and cell apoptosis was analyzed with annexinV/PI fluorescent staining. RESULTS Both CTE and ACE significantly reduced the viability and inhibited the migration of A549 cells, and high-dose ACE produced a significantly stronger inhibitory effect on cell migration than high- dose CTE (P < 0.01). ACE showed more potent inhibitory effect than CTE on the invasion of A549 cells (P < 0.01). Both CTE and ACE inhibited the expressions of MMP1 and MMP2 and up-regulated the level of IFN-γ without significantly affecting the levels of IL-1β and TNF-α. Annexin V/PI staining showed that both CTE and ACE caused apoptosis of A549 cells, but ACE had a stronger proapoptotic effect. CONCLUSIONS Processing with sodium hydroxide can significantly improve the antitumor activity of cantharides, which inhibits the proliferation, migration and invasion of A549 cells possibly by down-regulating the expressions of MMP1 and MMP2, promoting apoptosis and increasing the level of IFN-γ.

RSK3 mediates necroptosis by regulating phosphorylation of RIP3 in rat retinal ganglion cells. J Anat 2020; 237:29-47. [PMID: 32162697 PMCID: PMC7309291 DOI: 10.1111/joa.13185] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2019] [Revised: 02/19/2020] [Accepted: 02/24/2020] [Indexed: 12/15/2022] Open
Abstract
Receptor-interacting protein 3 (RIP3) plays an important role in the necroptosis signaling pathway. Our previous studies have shown that the RIP3/mixed lineage kinase domain-like protein (MLKL)-mediated necroptosis occurs in retinal ganglion cell line 5 (RGC-5) following oxygen-glucose deprivation (OGD). However, upstream regulatory pathways of RIP3 are yet to be uncovered. The purpose of the present study was to investigate the role of p90 ribosomal protein S6 kinase 3 (RSK3) in the phosphorylation of RIP3 in RGC-5 cell necroptosis following OGD. Our results showed that expression of RSK3, RIP3, and MLKL was upregulated in necroptosis of RGC-5 after OGD. A computer simulation based on our preliminary results indicated that RSK3 might interact with RIP3, which was subsequently confirmed by co-immunoprecipitation. Further, we found that the application of a specific RSK inhibitor, LJH685, or rsk3 small interfering RNA (siRNA), downregulated the phosphorylation of RIP3. However, the overexpression of rip3 did not affect the expression of RSK3, thereby indicating that RSK3 could be a possible upstream regulator of RIP3 phosphorylation in OGD-induced necroptosis of RGC-5 cells. Moreover, our in vivo results showed that pretreatment with LJH685 before acute high intraocular pressure episodes could reduce the necroptosis of retinal neurons and improve recovery of impaired visual function. Taken together, our findings suggested that RSK3 might work as an upstream regulator of RIP3 phosphorylation during RGC-5 necroptosis.

Abstract
:
Traumatic Brain Injury is considered one of the most prevalent causes of death around the world; more
than seventy millions of individuals sustain the condition per year. The consequences of traumatic brain injury on
brain tissue are complex and multifactorial, hence, the current palliative treatments are limited to improve patients’
quality of life. The subsequent hemorrhage caused by trauma and the ongoing oxidative process generated
by biochemical disturbances in the in the brain tissue may increase iron levels and reactive oxygen species. The
relationship between oxidative damage and the traumatic brain injury is well known, for that reason, diminishing
factors that potentiate the production of reactive oxygen species have a promissory therapeutic use. Iron chelators
are molecules capable of scavenging the oxidative damage from the brain tissue and are currently in use for ironoverload-
derived diseases.
:
Here, we show an updated overview of the underlying mechanisms of the oxidative damage after traumatic brain
injury. Later, we introduced the potential use of iron chelators as neuroprotective compounds for traumatic brain
injury, highlighting the action mechanisms of iron chelators and their current clinical applications.

Abstract
The human ether-a-go-go related gene (hERG) encodes the rapid delayed rectifier K+ channel. hERG not only serves an important role in heart muscle and cardiomyocyte excitability by regulating action potential repolarization, but also represents a selective advantage for cancer cell proliferation. Arsenic trioxide is a traditional Chinese medicine, which has been previously identified as an efficient tumor suppressor, particularly in the treatment of acute pro-myelocytic leukemia. However, studies have also reported that long-term exposure to arsenicals may lead to the formation of malignant tumors. In the present study, the effect of low-dose arsenic trioxide on the proliferation and apoptosis of tumor cells was investigated, as were the potential underlying mechanisms of this effect. The data demonstrated that low-dose arsenic trioxide (0.1 µM) enhanced the viability and apoptosis of tumor cells expressing hERG channels following long-term incubation. However, in tumor cells lacking hERG channels, low-dose arsenic trioxide had no effect. Therefore, we hypothesized that this hormesis effect of low-dose arsenic trioxide on tumor cells may be associated with the hERG channel. Furthermore, low dose arsenic trioxide promoted the hERG-channel current by changing the kinetics of channel gating and prolonging the open-channel stage. Simultaneously, high-dose As2O3 (1 or 10 µM) significantly reduced the expression of hERG in tumor cells compared with the control group, which resulted in reduced proliferation rate and promotion of apoptotic rate. The results of the present study demonstrate that the dual effects of arsenic trioxide on hERG channels vary according to concentration, resulting in the dual effects on tumor cells. This provides a theoretical basis for the potential clinical application of arsenic trioxide, suggesting that hERG channels are an important target in preventing and treating tumorigenesis during arsenicosis.

Abstract
In this study, we attempted to find out the underlying mechanism of Benzoapyrene and metastasis of lung cancer cells. We also did experiments to testify the connection between BaP and its potential target, TNF-α. Cell median lethal dose (IC50 ) of both cells was measured by crystal violet method. Quantitative real-time reverse transcription PCR (qRT-PCR) and Western blot were employed to detect the expression of TNF-α. Wound healing assay and transwell assay were utilized to testify the impacts of BaP and TNF-α on the metastasis of lung cancer cells. Cell death rate was elevated with the increase of BaP concentration. BaP increased the number of metastatic cells of lung cancer. The expressions of TNF-α pathway-associated protein (TNF-α, NF-kB [P65], Caspase3, and Caspase8) were enhanced by overexpressed BaP. TNF-α shRNA suppressed the positive effects of BaP on migration and invasion of lung cancer cells. Our study validated the positive effects of BaP on the metastasis of lung cancer cells. We also revealed the instrumental role of TNF-α in helping the development of lung cancer cells induced by BaP.

Abstract
Lung adenocarcinoma (LUAD) is a common cause of cancer-associated mortality. The dysregulation of microRNA (miR) expression has been reported to induce lung carcinogenesis. In the present study, miR-197-3p upregulation was detected within LUAD tissues compared with in adjacent noncancerous tissues. The suppression of miR-197-3p expression was confirmed to inhibit proliferative ability and induce apoptosis of LUAD cell lines; miR-197-3p overexpression within the HBE cell line exhibited opposing effects. Via in silico modeling, western blot analyses and dual-luciferase assays, it was confirmed that miR-197-3p directly targets the lysine 63 deubiquitinase (CYLD) gene. In the present study, the expression of miR-197-3p was negatively associated with CYLD mRNA expression within LUAD cell lines. In conclusion, the findings of the present study have provided novel insight into the association of miR-197-3p with LUAD proliferation and apoptotic regulation; the miR-197-3p/CYLD axis may serve as a novel potential therapeutic target for the treatment of LUAD.
