Aspongopus chinensis Dallas induces pro-apoptotic and cell cycle arresting effects in hepatocellular carcinoma cells by modulating miRNA and mRNA expression. Heliyon 2024; 10:e27525. [PMID: 38500987 PMCID: PMC10945178 DOI: 10.1016/j.heliyon.2024.e27525] [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: 11/08/2023] [Revised: 02/29/2024] [Accepted: 03/01/2024] [Indexed: 03/20/2024] Open
Abstract
Aspongopus chinensis Dallas is a traditional Chinese medicinal insect with several anticancer properties can inhibit cancer cell growth, by inhibiting cell division, autophagy and cell cycle. However, the precise therapeutics effects and mechanisms of this insect on liver cancer are still unknown. This study examined the inhibitory influence of A. chinensis on the proliferation of hepatocellular carcinoma (HCC) cells and explore the underlying mechanism using high-throughput sequencing. The results showed that A. chinensis substantially reduced the viability of Hep G2 cells. A total of 33 miRNAs were found to be upregulated, while 43 miRNAs were downregulated. Additionally, 754 mRNAs were upregulated and 863 mRNAs were downregulated. Significant enrichment of differentially expressed genes was observed in signaling pathways related to tumor cell growth, cell cycle regulation, and apoptosis. Differentially expressed miRNAs exhibited a targeting relationship with various target genes, including ARC, HSPA6, C11orf86, and others. Hence, cell cycle and apoptosis were identified by flow cytometry. These findings indicate that A. chinensis impeded cell cycle advancement, halted the cell cycle in the G0/G1 and S stages, and stimulated apoptosis. Finally, mouse experiments confirmed that A. chinensis significantly inhibits tumor growth in vivo. Therefore, our findings indicate that A. chinensis has a notable suppressive impact on the proliferation of HCC cells. The potential mechanism of action could involve the regulation of mRNA expression via miRNA, ultimately leading to cell cycle arrest and apoptosis. The results offer a scientific foundation for the advancement and application of A. chinensis in the management of HCC.

Abstract
Coridius chinensis is a traditional insect medicine in China. It is the dried whole insect of Coridius chinensis (Dallas) form the Pentatomidae family. Modern medical and pharmaceutical studies have successfully isolated and identified over 100 natural small molecular compounds from Coridius chinensis. These studies have also confirmed its various pharmacological activities, including analgesic, antioxidant, anticancer, anticoagulant, and antibacterial properties. Coridius chinensis is commonly used in traditional Chinese medicine preparations to treat impotence, hemangioma, pain and other diseases. However, more research is needed to fully explore the pharmacological effects of this herbal medicine. This paper aims to summarize both domestic and international research literature on Coridius chinensis, focusing on its main components, pharmacological activity and clinical application. The findings will provide valuable references for further research and development of Coridius chinensis as a traditional Chinese medicine resource.

Abstract
Neurotoxicity could be induced by long exposure to manganese (Mn). The traditional Chinese medicine, Corididius chinensis (Cc) has been proven to have a certain curative effect on Mn poisoning. Therefore, network pharmacology was performed to explore potential therapeutic targets and pharmacological mechanisms of Cc. We found ingredients by building our own database through literature, (which is the first to screen traditional Chinese medicine without traditional Chinese medicine systems pharmacology database and analysis platform databases and it is applicable whenever a Chinese medicine is not found in the traditional Chinese medicine systems pharmacology database and analysis platform database) and potential targets of Mn-induced nervous system diseases from the OMIM, GeneCards, and DrugBank database were identified. A protein-protein interaction network was constructed using Cytoscape. Gene ontology and Kyoto encyclopedia of genes and genomes pathway enrichment analysis was performed for the treatment of Mn-induced nervous system disease, and molecular docking was carried out to verify the results of network pharmacology analysis. After screening disease-related genes, 12 intersecting genes overlapped between 284 target proteins of the active compound and 195 potential disease targets. The pathways of neurodegeneration_multiple diseases and Alzheimer disease pathway may be the most potential pathway of Cc treating Mn-induced nervous system diseases. CASP9 and PTGS2 in neurodegeneration_multiple diseases, NOS1, NOS2 in Alzheimer disease pathway were identified as core targets. Especially, molecule docking analysis unveil that aspongpyrazine A docking NOS2 is the most potential therapeutic drug and target, which primarily involved in the processes of oxidative stress and inflammation.

Mixed exposure effect of seminal metals on semen quality, mediation of total antioxidant capacity, and moderation of GSTM1/GSTT1 gene deletion in Chinese reproductive-aged men. ENVIRONMENTAL RESEARCH 2023; 229:115888. [PMID: 37054833 DOI: 10.1016/j.envres.2023.115888] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 04/06/2023] [Accepted: 04/11/2023] [Indexed: 05/21/2023]
Abstract
BACKGROUND The effects of metal exposure on semen quality and the role of oxidative damage in this process remain unclear. METHODS We recruited 825 Chinese male volunteers, and 12 seminal metals (Mn, Cu, Zn, Se, Ni, Cd, Pb, Co, Ag, Ba, Tl, and Fe), the total antioxidant capacity (TAC), and reduced glutathione were measured. Semen parameters and GSTM1/GSTT1-null genotypes were also detected. Bayesian kernel machine regression (BKMR) was applied to evaluate the effect of the mixed exposure to metals on semen parameters. The mediation of TAC and moderation of GSTM1/GSTT1 deletion were analyzed. RESULTS Most seminal metal concentrations were correlated with each other. The BKMR models revealed a negative association between the semen volume and metal mixture, with Cd (cPIP = 0.60) and Mn (cPIP = 0.10) as the major contributors. Compared to fixing all scaled metals at their median value (50th percentiles), fixing the scaled metals at their 75th percentiles decreased the TAC by 2.17 units (95%CI: -2.60, -1.75). Mediation analysis indicated that Mn decreased the semen volume, with 27.82% of this association mediated by TAC. Both the BKMR and multi-linear models showed that seminal Ni was negatively correlated with sperm concentration, total sperm count, and progressive motility, which was modified by GSTM1/GSTT1. Furthermore, Ni and the total sperm count showed a negative association in GSTT1 and GSTM1 null males (β[95%CI]: 0.328 [-0.521, -0.136]) but not in males with GSTT1 and/or GSTM1. Although Fe and the sperm concentration and total sperm count were positively correlated, they showed inverse "U" shapes in univariate analysis. CONCLUSION Exposure to the 12 metals was negatively associated with semen volume, with Cd and Mn as the major contributors. TAC may mediate this process. GSTT1 and GSTM1 can modify the reduction in the total sperm count caused by seminal Ni exposure.

Abstract
Entomoceuticals define a subset of pharmaceuticals derived from insects. The therapeutic effect of insect-derived drugs has been empirically validated by the direct use of various folk medicines originating from three sources in particular: the glandular secretions of insects (e.g., silk, honey, venom), the body parts of the insect or the whole used live or by various processing (e.g., cooked, toasted, ground), and active ingredients extracted from insects or insect-microbe symbiosis. Insects have been widely exploited in traditional Chinese medicine (TCM) relative to other ethnomedicines, especially in the prospect of insect species for medicinal uses. It is noticeable that most of these entomoceuticals are also exploited as health food for improving immune function. In addition, some edible insects are rich in animal protein and have high nutritional value, which are used in the food field, such as insect wine, health supplements and so on. In this review, we focused on 12 insect species that have been widely used in traditional Chinese herbal formulae but have remained less investigated for their biological properties in previous studies. We also combined the entomoceutical knowledge with recent advances in insect omics. This review specifies the underexplored medicinal insects from ethnomedicine and shows their specific medicinal and nutritional roles in traditional medicine.

Abstract
Human infertility has become the third largest serious disease in the world, seriously affecting the quality of human fertility. Studies have shown that manganese (Mn) can accumulate in the testis through the blood-testicular barrier and damage the male reproductive system. However, the mechanism has not been explored clearly. Recent studies have reported that YTH domain-containing 2 (YTHDC2) can regulate reproductive function. However, none has explored the role of YTHDC2 in Mn-induced reproductive toxicity. The present study investigated whether YTHDC2/CyclinB2 (CCNB2) pathway participates in Mn-induced reproductive toxicity using Kunming mice, spermatogonia, and the seminal plasma of male workers. The mice were received intraperitoneal (i.p.) injections of 0, 12.5, 25, and 50 mg/kg MnCl2 once daily for 2 weeks. The cells were treated with 0, 100, 200 and 400 μM MnCl2 for 24 h. Here, we found that occupational Mn exposure significantly increased Mn levels in the seminal plasma of male workers, while decreased sperm density, semen quality, and the levels of YTHDC2, CCNB1, and CCNB2. We found that Mn can inhibit the YTHDC2/CCNB2 signaling pathway and block the G2/M phase of the cell cycle. Moreover, the morphology of cells and the histomorphology of mice testis were injured. Notably, over-expression (OE) of YTHDC2 increased CCNB2 levels, reduced cell cycle arrest, and improved reproductive toxicity after Mn exposure. These findings suggest that the YTHDC2/CCNB2 signaling pathway participates in Mn-induced reproductive toxicity, and OE of YTHDC2 can mitigate the toxicity of Mn.

Abstract
Manganese (Mn2+ ) is an environmental pollutant, and testis is one of the main target organs. Coridius chinensis (C. chinensis), a traditional Chinese medicine, has been shown widely used in treating various kinds of pain, nephropathy and erectile dysfunction. In our recent study, we found that Mn2+ exposure caused testicular injury could be rescued in part by the antioxidant activity of C. chinensis extracts (CcE). However, there is dearth of extensive knowledge on the therapeutic effects of C. chinensis on manganese-induced reproductive toxicity. In the present study, Sprague-Dawley (SD) rats were administered manganese chloride alone or co-treated with CcE for 30 consecutive days. Results indicated that C. chinensis mediated suppression of spermatogenic dysfunction, and the number of apoptotic cells was significantly decreased in CcE-treated groups. Furthermore, the disintegrated testicular ultrastructural structure caused by Mn2+ was partially repaired in CcE-treated groups. C. chinensis significantly inhibited Mn2+ -induced decline in biomarkers of blood-testis barrier (BTB) including occludin, claudin1, zonula occludens-1 and junctional adhesion molecule 1, whereas it decreased the expression of focal adhesion kinase (FAK) and c-Src. This study demonstrated that c-Src and FAK might be involved in the repair of Mn2+ -induced testicular injury by C. chinensis, but further research is needed.

Abstract
Infertility is regarded as a global health problem affecting 8-12% of couples. Male factors are regarded as the main cause of infertility in 40% of infertile couples and contribute to this condition in combination with female factors in another 20% of cases. Abnormal sperm parameters such as oligospermia, asthenospermia, and teratozoospermia result in male factor infertility. Several studies have shown the deteriorative impact of heavy metals on sperm parameters and fertility in human subjects or animal models. Other studies have pointed to the role of antioxidants in counteracting the detrimental effects of heavy metals. In the currents study, we summarize the main outcomes of studies that assessed the counteracting impacts of heavy metal and antioxidants on male fertility. Based on the provided data from animal studies, it seems rational to administrate appropriate antioxidants in persons who suffer from abnormal sperm parameters and infertility due to exposure to toxic elements. Yet, further human studies are needed to approve the beneficial effects of these antioxidants.

Pomegranate Seeds Extract Possesses a Protective Effect against Tramadol-Induced Testicular Toxicity in Experimental Rats. BIOMED RESEARCH INTERNATIONAL 2020; 2020:2732958.

Abstract
Tramadol is a centrally acting opioid analgesic that is extensively used. The chronic exposure to tramadol induces oxidative stress and toxicity especially for patients consuming it several times a day. Previously, we and others reported that tramadol induces testicular damage in rats. This study was conducted to investigate the possible protective effect of pomegranate seed extract (PgSE) against tramadol-induced testicular damage in adult and adolescent rats. Male rats were orally treated with tramadol or in a combination with PgSE for three weeks. Testes were then dissected and analyzed. Histological and ultrastructural examinations indicated that tramadol induced many structural changes in the testes of adult and adolescent rats including hemorrhage of blood vessels, intercellular spaces, interstitial vacuoles, exfoliation of germ cells in lumen, cell apoptosis, chromatin degeneration of elongated spermatids, and malformation of sperm axonemes. Interestingly, these abnormalities were not observed in tramadol/PgSE cotreated rats. The morphometric analysis revealed that tramadol disrupted collagen metabolism by elevating testicular levels of collagen fibers but that was protected in tramadol/PgSE cotreatment at both ages. In addition, DNA ploidy revealed that S phase of the cell cycle was diminished when adult and adolescent rats were treated with tramadol. However, the S phase had a normal cell population in the cotreated adult rats, but adolescent rats had a lower population than controls. Furthermore, the phytochemistry of PgSE revealed a high content of total polyphenols and total flavonoids within this extract; besides, the DPPH free radical scavenging activity was high. In conclusion, this study indicated that PgSE has a prophylactic effect against tramadol-induced testicular damage in both adult and adolescent ages, although the tramadol toxicity was higher in adolescent age to be completely protected. This prophylactic effect might be due to the high antioxidant compounds within the pomegranate seeds.
