Abstract
Gleditsia sinensis, commonly known as Chinese Zaojiao, has important economic value and medicinal compounds in its fruits and thorns, making it widely cultivated artificially in China. However, the available literature on the impact of waterlogging on the growth of G. sinensis seedlings and the accumulation of metabolite compounds in its thorns is limited. To address this knowledge gap, G. sinensis seedlings were planted in soil supplemented with pindstrup substrate, which enhances the water-holding capacity of the soil. The analyses of morphological traits and nutrient elements in one-year-old G. sinensis seedlings grown naturally under ambient conditions and metabolite accumulation in its thorns were conducted. The results showed that the waterlogged soil significantly diminished the height, fresh weight, and dry weight of seedling roots and stems (P < 0.05). Furthermore, waterlogging hindered the uptake of iron (Fe) and manganese (Mn), as well as the transport of potassium (K). The identified metabolites within the thorns were categorized into 16 distinct groups. Relative to the control soil, fatty acids and derivatives were the most down-regulated metabolites in the waterlogged soil, accounting for 40.58% of the total metabolites, followed by lignans (38.71%), phenolic acids (34.48%), saccharides and alcohols (34.15%), steroids (16.67%), alkaloids (12.24%), flavonoids (9.28%), and glycerophospholipids (7.41%). Conversely, nucleotides and derivatives experienced the greatest up-regulation in the waterlogged soil, accounting for 50.00% of the total metabolites. In conclusion, waterlogging negatively impacted the growth of G. sinensis seedlings and inhibited the accumulation of metabolites. Hence, when considering the accumulation of secondary metabolites such as lignans and phenolic acids, appropriate management of soil moisture levels should be taken into account.

Abstract
As an economically important tree, Gleditsia sinensis Lam. is widely planted. A lack of background genetic information on G. sinensis hinders molecular breeding. Based on PacBio single-molecule real-time (SMRT) sequencing and analysis of G. sinensis, a total of 95,183 non-redundant transcript sequences were obtained, of which 93,668 contained complete open reading frames (ORFs), 2,858 were long non-coding RNAs (LncRNAs) and 18,855 alternative splicing (AS) events were identified. Genes orthologous to different Gleditsia species pairs were identified, stress-related genes had been positively selected during the evolution. AGA, AGG, and CCA were identified as the universal optimal codon in the genus of Gleditsia. EIF5A was selected as a suitable fluorescent quantitative reference gene. 315 Cytochrome P450 monooxygenases (CYP450s) and 147 uridine diphosphate (UDP)-glycosyltransferases (UGTs) were recognized through the PacBio SMRT transcriptome. Randomized selection of GsIAA14 for cloning verified the reliability of the PacBio SMRT transcriptome assembly sequence. In conclusion, the research data lay the foundation for further analysis of the evolutionary mechanism and molecular breeding of Gleditsia.

Abstract
Objective In this study, network pharmacology, bioinformatics and molecular docking were used to explore the active phytochemicals, hub genes, and potential molecular mechanisms of Gleditsiae Spina in treating of colorectal cancer.. Methods The targets of Gleditsiae Spina, and targets related to CRC were derived from databases. We identified the hub genes for Gleditsiae Spina anti-colorectal cancer following the protein-protein-interaction (PPI) network. Furthermore, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment were used to analyze the hub genes from a macro perspective. Finally, we verified the hub genes by molecular docking, GEPIA, HPA, and starBase database. Results We identified nine active phytochemicals and 36 intersection targets. The GO enrichment analysis results showed that Gleditsiae Spina may be involved in gene targets affecting multiple biological processes, including response to radiation, response to ionizing radiation, cyclin-dependent protein kinase holoenzyme complex, serine/threonine protein kinase complex, cyclin-dependent protein serine/threonine kinase regulator activity and protein kinase regulator activity. KEGG enrichment analysis results indicated that the P53 signaling pathway, IL-17 signaling pathway, Toll-like receptor signaling pathway, PI3K-Akt signaling pathway, and JAK-STAT signaling pathway were mainly related to the effect of Gleditsiae Spina on colorectal cancer. Molecular docking analysis suggested that the active phytochemicals of Gleditsiae Spina could combine well with hub genes (PTGS1, PIK3CG, CCND1, CXCL8 and ADRB2). Conclusion This study provides clues for further study of anti-CRC phytochemicals as well as their mechanisms of provides a basis for their development model.

Cell Oncol 2022; 45:1073-1117. [PMID: 36149600 DOI: 10.1007/s13402-022-00715-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/03/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Gastric cancer imposes a substantial global health burden despite its overall incidence decrease. A broad spectrum of inherited, environmental and infectious factors contributes to the development of gastric cancer. A profound understanding of the molecular underpinnings of gastric cancer has lagged compared to several other tumors with similar incidence and morbidity rates, owing to our limited knowledge of the role of carcinogens in this malignancy. The International Agency for Research on Cancer (IARC) has classified gastric carcinogenic agents into four groups based on scientific evidence from human and experimental animal studies. This review aims to explore the potential comprehensive molecular and biological impacts of carcinogens on gastric cancer development and their interactions and interferences with various cellular signaling pathways. CONCLUSIONS In this review, we highlight recent clinical trial data reported in the literature dealing with different ways to target various carcinogens in gastric cancer. Moreover, we touch upon other multidisciplinary therapeutic approaches such as surgery, adjuvant and neoadjuvant chemotherapy. Rational clinical trials focusing on identifying suitable patient populations are imperative to the success of single-agent therapeutics. Novel insights regarding signaling pathways that regulate gastric cancer can potentially improve treatment responses to targeted therapy alone or in combination with other/conventional treatments. Preventive strategies such as control of H. pylori infection through eradication or immunization as well as dietary habit and lifestyle changes may reduce the incidence of this multifactorial disease, especially in high prevalence areas. Further in-depth understanding of the molecular mechanisms involved in the role of carcinogenic agents in gastric cancer development may offer valuable information and update state-of-the-art resources for physicians and researchers to explore novel ways to combat this disease, from bench to bedside. A schematic outlining of the interaction between gastric carcinogenic agents and intracellular pathways in gastric cancer H. pylori stimulates multiple intracellular pathways, including PI3K/AKT, NF-κB, Wnt, Shh, Ras/Raf, c-MET, and JAK/STAT, leading to epithelial cell proliferation and differentiation, apoptosis, survival, motility, and inflammatory cytokine release. EBV can stimulate intracellular pathways such as the PI3K/Akt, RAS/RAF, JAK/STAT, Notch, TGF-β, and NF-κB, leading to cell survival and motility, proliferation, invasion, metastasis, and the transcription of anti-apoptotic genes and pro-inflammatory cytokines. Nicotine and alcohol can lead to angiogenesis, metastasis, survival, proliferation, pro-inflammatory, migration, and chemotactic by stimulating various intracellular signaling pathways such as PI3K/AKT, NF-κB, Ras/Raf, ROS, and JAK/STAT. Processed meat contains numerous carcinogenic compounds that affect multiple intracellular pathways such as sGC/cGMP, p38 MAPK, ERK, and PI3K/AKT, leading to anti-apoptosis, angiogenesis, metastasis, inflammatory responses, proliferation, and invasion. Lead compounds may interact with multiple signaling pathways such as PI3K/AKT, NF-κB, Ras/Raf, DNA methylation-dependent, and epigenetic-dependent, leading to tumorigenesis, carcinogenesis, malignancy, angiogenesis, DNA hypermethylation, cell survival, and cell proliferation. Stimulating signaling pathways such as PI3K/Akt, RAS/RAF, JAK/STAT, WNT, TGF-β, EGF, FGFR2, and E-cadherin through UV ionizing radiation leads to cell survival, proliferation, and immortalization in gastric cancer. The consequence of PI3K/AKT, NF-κB, Ras/Raf, ROS, JAK/STAT, and WNT signaling stimulation by the carcinogenic component of Pickled vegetables and salted fish is the Warburg effect, tumorigenesis, angiogenesis, proliferation, inflammatory response, and migration.

Abstract
Gastrointestinal cancers (GICs) and neuroendocrine tumors (NETs) are often refractory to therapy after metastasis. Adoptive cell therapy using chimeric antigen receptor (CAR) T cells, though remarkably efficacious for treating leukemia, is yet to be developed for solid tumors such as GICs and NETs. Here we isolated a llama-derived nanobody, VHH1, and found that it bound cell surface adhesion protein CDH17 upregulated in GICs and NETs. VHH1-CAR T cells (CDH17CARTs) killed both human and mouse tumor cells in a CDH17-dependent manner. CDH17CARTs eradicated CDH17-expressing NETs and gastric, pancreatic and colorectal cancers in either tumor xenograft or autochthonous mouse models. Notably, CDH17CARTs do not attack normal intestinal epithelial cells, which also express CDH17, to cause toxicity, likely because CDH17 is localized only at the tight junction between normal intestinal epithelial cells. Thus, CDH17 represents a class of previously unappreciated tumor-associated antigens that is 'masked' in healthy tissues from attack by CAR T cells for developing safer cancer immunotherapy.

Abstract
INTRODUCTION Flavonoids are the most important and effective constituents in the thorns of Gleditsia sinensis Lam., which have been known to show antimicrobial, antiviral, anticancer, and anticoagulant activities. However, efficient extraction and separation methods for these flavonoids are not currently established. OBJECTIVE To develop an efficient method for efficient extraction and rapid separation of flavonoids from the thorns of G. sinensis using choline chloride deep eutectic solvents (DESs) and high-speed counter-current chromatography (HSCCC). METHODOLOGY As for extraction, DES composed of choline chloride and 1,4-butanediol at 1:4 mole ratio, at an extraction temperature of 55°C, 20% of water content, 1:30 mg/mL for solid-liquid ratio, and 45 min for extraction time were selected as the optimised extraction method for flavonoids from the thorns of G. sinensis. As for separation, dichloromethane-methanol-n-butanol-water (4:3:0.5:2, v/v) was applied to develop a successful strategy for purification of the flavonoids by HSCCC. RESULTS Totally, five flavonoids, including padmatin (1, 3.7 mg), isovitexin (2, 2.5 mg), 3',5,5',7-tetrahydroxyflavanonol (3, 11.2 mg), 7,4'-dihydroxy-5,3'-dimethoxyflavanonol (4, 4.1 mg), and quercetin (5, 3.8 mg), were successfully obtained from 250 mg of the extracted flavonoids by HSCCC. CONCLUSION Results demonstrated that the combination of DES and HSCCC is a powerful technique for the extraction, and isolation of flavonoids from the thorns of G. sinensis compared with conventional organic solvent extraction and column chromatography, which have been proven to provide higher extraction efficiency for flavonoids and rapidly obtain the quality control markers of flavonoids from the investigated plant.

Abstract
Chloroplast genomes have been widely considered an informative and valuable resource for molecular marker development and phylogenetic reconstruction in plant species. This study evaluated the complete chloroplast genomes of the traditional Chinese medicine Gleditsia sinensis and G. japonica, an adulterant of the former. The complete chloroplast genomes of G. sinensis and G. japonica were found to be of sizes 163,175 bp and 162,391 bp, respectively. A total of 111 genes were identified in each chloroplast genome, including 77 coding sequences, 30 tRNA, and 4 rRNA genes. Comparative analysis demonstrated that the chloroplast genomes of these two species were highly conserved in genome size, GC contents, and gene organization. Additionally, nucleotide diversity analysis of the two chloroplast genomes revealed that the two short regions of ycf1b were highly diverse, and could be treated as mini-barcode candidate regions. The mini-barcode of primers ZJ818F-1038R was proven to precisely discriminate between these two species and reflect their biomass ratio accurately. Overall, the findings of our study will shed light on the genetic evolution and guide species identification of G. sinensis and G. japonica.

Abstract
Spina Gleditsia has been traditionally used as a lead ingredient of many formulas for cancer treatment in Traditional Chinese Medicine. This work aimed to reveal the phytochemical foundation of Spina Gleditsiae and underpin a fundamental understanding of its anticancer activities. The growth inhibition activities were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay of 7 solvent extracts of Spina Gleditsia in the human liver cancer cell line HepG2. The activities were then mapped onto the secondary metabolite profile of crude extracts by principal components analysis (PCA) of High Performance Liquid Chromatography-Ultraviolet (HPLC-UV) data. The top 5 PCA components of the map discriminated extract activities, mainly based on the differential content of 3 compounds. The identified compounds were then tested individually using cytotoxic assay on cancer cells in vitro. Principal components analysis constructed secondary metabolite mapping quickly identified functional compounds from the crude herbal extracts. (2 R,3 R)-7,3′,4′-Trihydroxy-5-methoxy-flavanonol, (2 R,3 R)-5,7,3′-trihydroxy-4′-methoxy-flavanonol, and isovitexin inhibited the growth of human liver cancer cell line growth with activities of 38.6 ± 1.9, 40.7 ± 0.9, and 41.5 ± 3.1 μg/mL, respectively, comparable with that of cisplatin (IC50: 41.6 ± 2.9 μg/mL). (2 R,3 R)-7,3′,4′-Trihydroxy-5-methoxy-flavanonol, (2 R,3 R)-5,7,3′-trihydroxy-4′-methoxy-flavanonol, and isovitexin are, for the first time, identified as the anticancer constituents of Spina Gleditsia. It thus strongly underpins a fundamental understanding of the anticancer activities of Spina Gleditsia and supports its ongoing clinical uses in China.

Abstract
Quxie capsule (QX), a herbal remedy used in traditional Chinese medicine, is routinely used in advanced colorectal cancer treatment in Xiyuan Hospital in Beijing, China. However, the mechanism(s) underlying the effect of QX in colorectal cancer remain unclear, which hampers the optimal use of QX for the treatment of the disease. The transcription factor forkhead box O1 (Foxo1) plays important roles in regulation of cell cycle, apoptosis, and immune response in various cancers. In this study, we examined the antitumor efficacy of QX in a mouse model of colorectal cancer and further investigated the mechanism by which QX regulated Foxo1 protein-mediated pathways. QX administered via gavage daily for 2 weeks in mice carrying CT26 mouse colon tumors resulted in significantly lower mean tumor weight (0.93 ± 0.32 g) compared with that in vehicle control-treated mice (1.57 ± 0.57 g, P <.05). Foxo1 protein expression in tumors was also higher in the QX group than that in the vehicle control group. Furthermore, QX treatment upregulated apoptotic proteins such as Fas, Bim, and cleaved caspase-3 in tumor tissue compared with those in the vehicle control group. Intriguingly, the ratios of Th1/Th2 and Th17/Treg cells and levels of T-bet protein (the key regulator of Th1 and Th2 cells) were higher while the level of Foxp3 (the key regulator of Treg cells) was lower in QX-treated mice compared to vehicle control mice, revealing that Foxo1 upregulated T-bet and downregulated Foxp3 and induced a shift in immune balance. This shift could be critical in the antitumor efficacy of QX. Furthermore, knocking down Foxo1 in human colon cancer HCT116 cells partially blocked the effect of QX-elicited antiproliferative activity. Together, these results suggest that QX exerts antitumor activity in CT26 mouse colon cancer model partially mediated by Foxo1-induced apoptosis and antitumor immune response.

Abstract
One new triterpenoid saponin (1), as well as six known ones (2-7), were isolated from the ethanol extract of the thorns of Gleditsia sinensis. Their structures were elucidated by extensive spectroscopic analysis in conjunction with chemical evidence. Cytotoxic activity of compounds 1-6 was evaluated against human breast cancer MCF 7 cells in vitro by the MTT method. Our results revealed moderate activities for compounds 1-6 with IC50 values of 18.43, 30.47, 18.46, 10.02, 30.76, and 17.32 μM, respectively. Furthermore, compounds 1, 3, 4, and 6 induced apoptosis in MCF 7 cell, with 1 and 6 causing late apoptosis of MCF 7 cells, while 3 and 4 acting oppositely.

Abstract
Lung cancer has substantial mortality worldwide, and chemotherapy is a routine regimen for the treatment of patients with lung cancer, despite undesirable effects such as drug resistance and chemotoxicity. Here, given a possible antitumor effect of the fruit hull of Gleditsia sinensis (FGS), we tested whether FGS enhances the effectiveness of cis-diammine dichloridoplatinum (II) (CDDP), a chemotherapeutic drug. We found that CDDP, when administered with FGS, significantly decreased the viability and increased the apoptosis and cell cycle arrest of Lewis lung carcinoma (LLC) cells, which were associated with the increase of p21 and decreases of cyclin D1 and CDK4. Concordantly, when combined with FGS, CDDP significantly reduced the volume and weight of tumors derived from LLC subcutaneously injected into C57BL/6 mice, with concomitant increases of phosphor-p53 and p21 in tumor tissue. Together, these results show that FGS could enhance the antitumor activity of CDDP, suggesting that FGS can be used as a complementary measure to enhance the efficacy of a chemotherapeutic agent such as CDDP.

Abstract
Gleditsia sinensis thorns (GST) have been used as a traditional medicine for carbuncles and skin diseases. The purpose of this study was to decide whether non-toxicological levels of water extract of GST (WEGST) are effective in inhibiting the progress of prostate cancer formation and to identify the target molecule involved in the WEGST-mediated inhibitory process of prostate cancer cell migration and in vivo tumor formation. Through the Boyden chamber migration assay, we found that non-toxic levels of WEGST could not attenuate the PC3 migration to the bottom area coated with serum but significantly inhibited PC3 cell migration to the collagen-coated bottom area. We also found that non-toxic levels of WEGST significantly attenuated collagen against adhesion. Interestingly, ectopic administration of WEGST could not affect the expression of α2β1 integrin, which is known as a receptor of collagen. However, when the PC3 cells adhered to a collagen-coated plate, the expression of α2 integrin but not that of β1 integrin was significantly inhibited by the administration of non-toxic levels of WEGST, leading to the inhibition of focal adhesion kinase (FAK) phosphorylation. Furthermore, oral administration of WEGST (25 mg/kg/day) significantly inhibited the size of a PC3 cell-xenografted tumor. Taken together, these results suggest a novel molecular mechanism for WEGST to inhibit prostate cancer progression at particular stages, such as collagen-mediated adhesion and migration, and it might provide further development for the therapeutic use of WEGST in the treatment of prostate cancer progression.

Abstract
Angiogenesis is the process of new vessel formation from pre-existing blood vasculature and is critical for continuous tumor growth. We previously reported that an ethanolic extract of Gleditsia sinensis thorns (EEGS) and its active constituent, cytochalasin H, have anti-angiogenic activity in vitro and in vivo via suppression of endothelial cell functions. In the present study, EEGS and cytochalasin H were observed to efficiently inhibit tumor growth in an in ovo xenograft model without significant toxicity. We repeatedly observed the anti-tumor and anti-metastatic effects of EEGS in representative animal models. These results suggest that EEGS and its active constituent, cytochalasin H, are potential candidates for the development of anti-angiogenic cancer drugs.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The plants in the genus Gleditsia, mainly distributed in central and Southeast Asia and North and South America, have been used as local and traditional medicines in many regions, especially in China, for the treatment of measles, indigestion, whooping, smallpox, arthrolithiasis, constipation, diarrhea, hematochezia, dysentery, carbuncle, etc. This present paper systemically reviews the miscellaneous information surrounding its traditional use, phytochemistry and pharmacology to provide opportunities and recommendations for the future research. MATERIALS AND METHODS The scientific literatures were systematically searched from scientific databases (PubMed, Scopus, Elsevier, SpringerLink, SciFinder, Google Scholar and others). In addition, the ethnopharmacological information on this genus was mainly acquired from Chinese and Korean herbal classics, and library catalogs. RESULTS More than 60 compounds including triterpenes, sterols, flavonoids, alkaloids, phenolics and their derivatives were isolated from Gleditsia japonica Miq., Gleditsia sinensis Lam., Gleditsia caspica Desf. and Gleditsia triacanthos L. Among these compounds, triterpenoid saponins were the main constituents of Gleditsia species. Moreover, the crude extracts and purified molecules were tested, revealing diverse biological activities such as anti-tumor, anti-inflammatory, anti-allergic, anti-hyperlipidemic, analgesic, antimutagenic, antioxidant, anti-HIV, antibacterial, antifungal activities, etc. Among these biological studies, the possible mechanisms of antitumor action are stressed in this review, and these include causing cytotoxicity to cancer cells, inhibition of proliferation of cancer cells by affecting their growth, regeneration and apoptosis, inhibition of basic fibroblast growth factor (bFGF) and nitric oxide (NO), modulation of the oncogenic expression and telomerase activity results, inhibition of the expression of pro-angiogenic proteins, as well as down-regulation of intra/extracellular proangiogenic modulators, etc. CONCLUSIONS On the basis of preliminary research on Gleditsia genus it could be stated that saponins investigations may be more promising in future. Although 32 compounds of 67 identified compounds were saponins, modern pharmacological research on saponins were not a priority in Gleditsia species. Therefore, more bioactive experiments and in-depth mechanisms of action are required for elucidating their roles in physiological systems. Moreover, the present review also highlights that analgesic, anti-tumor and anti-HIV activities should have priority in saponins research. Additionally, it is imperative to explore more structure-activity relationships and possible synergistic actions of triterpenoid saponins for revaluating their pharmacological activities.

Abstract
Tumor suppressor molecules play a pivotal role in regulating DNA repair, cell proliferation, and cell death, which are also important processes in the pathogenesis of Alzheimer’s disease. Alzheimer’s disease is the most common neurodegenerative disorder, however, the precise molecular events that control the death of neuronal cells are unclear. Recently, a fundamental role for tumor suppressor molecules in regulating neurons in Alzheimer’s disease was highlighted. Generally, onset of neurodegenerative diseases including Alzheimer’s disease may be delayed with use of dietary neuro-protective agents against oxidative stresses. Studies suggest that dietary antioxidants are also beneficial for brain health in reducing disease-risk and in slowing down disease-progression. We summarize research advances in dietary regulation for the treatment of Alzheimer’s disease with a focus on its modulatory roles in BRCA1 and p53 tumor suppressor expression, in support of further therapeutic research in this field.
