Abstract
E6 and E7 human papillomavirus (HPV) oncoproteins play a significant role in the malignant transformation of infected cervical cancer cells via suppression of tumour suppressor pathways by targeting p53 and pRb, respectively. This study aimed to investigate the anticancer effects of Oroxylum indicum (OI) leaves' methanol extract on SiHa cervical cancer cells. Expression of apoptosis-related proteins (Bcl-2, caspase (cas)-3, and cas-9), viral oncoproteins (E6 and E7), and tumour suppressor proteins (p53 and pRb) were evaluated using western blot analysis before and after E6/E7 small interfering RNAs (siRNAs) transfection. In addition, the E6/E7 mRNA expression levels were assessed with real-time (RT)-PCR. The present study showed that the OI extract effectively hindered the proliferation of SiHa cells and instigated increments of cas-3 and cas-9 expressions but decreased the Bcl-2 expressions. The OI extract inhibited E6/E7 viral oncoproteins, leading to upregulation of p53 and pRb tumour suppressor genes in SiHa cells. Additionally, combinatorial treatment of OI extract and gossypin flavonoid induced restorations of p53 and pRb. Treatment with OI extract in siRNA-transfected cells also further suppressed E6/E7 expression levels and further upregulations of p53 and pRb proteins. In conclusion, OI extract treatment on siRNAs-transfected SiHa cells can additively and effectively block E6- and E7-dependent p53 and pRb degradations. All these data suggest that OI could be explored for its chemotherapeutic potential in cervical cancer cells with HPV-integrated genomes.

Genipin inhibits proliferation of gastric cancer cells by inducing ferroptosis: an integrated study of network pharmacology and bioinformatics study. Med Oncol 2024; 41:46. [PMID: 38175425 DOI: 10.1007/s12032-023-02283-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 12/07/2023] [Indexed: 01/05/2024]
Abstract
Ferroptosis has been demonstrated to suppress cancer development and is targeted for cancer therapy. Genipin, an iridoid constituent in Gardeniae Fructus, has been reported to exert anti-cancer abilities. However, whether genipin could induce ferroptosis remains unclear. The purpose of this study is to explore the anti-gastric cancer (GC) effects of genipin by inducing ferroptosis and to identify the potential targets. CCK-8 and colony formation assays were performed to evaluate the anti-GC effects of genipin. Flowcytometry and western blot were used to indicate ferroptosis-inducing ability of genipin. The potential targets of genipin were analyzed by network pharmacology, screened using UALCAN and KM-plotter database and evaluated by molecular docking. The results showed that genipin inhibited cell viability and proliferation of GC cells. Genipin treatment decreased levels of GPX4 and SLC7A11, induced accumulation of lipid peroxidation intracellularly and led to ferroptosis in GC cells. Network pharmacology analysis identified that lipid- and ROS-related pathways involved in ferroptosis ranked high among genipin-GC common targets. Data from UALCAN and KM-plotter database demonstrated that expression levels of ferroptosis-related targets, including AURKA, BCAT2, DHODH, and GPI, increased in GC tissues and the higher levels of the above four targets were related to tumor stage, tumor grade, and poor prognosis. Among these four targets, AURKA, BCAT2, and DHODH were confirmed by molecular docking with binding energies less than - 5. Taken together, our study demonstrates that genipin could exert anti-GC ability by inducing ferroptosis and provides evidence for the potential application of genipin in GC treatment.

Abstract
Purpose: The aim of this study is to explore the effects of gossypin on matrix metalloproteinases -2 (MMP-2) and MMP-9 genes in prostate cancer cells.
Materials and Methods: PC3 cells were grown in culture and treated with three different concentrations of gossypin (25-50-100 µg/ml) and cisplatin (50 µM) as a positive control. First, RNA isolation was performed. Then, cDNA synthesis was performed and RT-PCR was used to evaluate mRNA expression levels of MMP-2 and MMP-9 genes.
Results: Gossypin decreased MMP-2 and MMP-9 mRNA expression in prostate cancer cells in a concentration-dependent manner. Three concentrations (25-50-100 µg/ml) of gossypin in PC3 cells reduced the mRNA expression of the MMP-2 gene. While the fold change value of MMP-2 gene expression was 0.3482 ± 0.040 (mean ± sd) in the 100 µg/ml gossypin group, it was 1.007 ± 0.1425 (mean ± sd) in the control group. In addition, 50 µg/ml and 100 µg/ml concentrations of gossypin decreased the mRNA expression of the MMP-9 gene. The expression level of the MMP-9 gene in prostate cancer cells was 0.4740 ± 0.038 (mean ± sd) in the 100 µg/ml gossypin administered group, while it was 1.009 ± 0.1687 (mean ± sd) in the control group. There was a positive correlation between the expressions of the MMP-2 and MMP-9 genes.
Conclusion: According to the results obtained, it is seen that gossypin reduces the expression of MMP-2 and MMP-9 genes in prostate cancer cells and the effects of gossypin on other genetic and epigenetic mechanisms in cancer need to be investigated to reveal the anti-cancer.

Abstract
Amaç: Bu çalışmanın amacı, gossypin'in farklı kanser hücre hatlarında ısı şok proteinleri (HSP) genlerinin ekspresyon seviyesi üzerindeki etkisini incelemektir.
Gereç ve Yöntem: Hücreler, standart kültür koşulları altında büyütüldü. Kanser hücreleri, farklı konsantrasyonlarda (5-100 µg/ml) gossypin ve pozitif kontrol olarak sisplatin (50 µM) ile muamele edildi. Gossypin'in hücre canlılığı ve etkili doz aralığı (5-100 µg/ml), 24, 48 ve 72. saatlerde MTT ile belirlendi. RNA izolasyonu ve cDNA sentezinden sonra, HSP60 ve HSP70 gen ekpresyon seviyesi RT-PCR ile analiz edildi. Gen ekspresyonu için 2-∆∆ct methodu kullanıldı.
Bulgular: MTT sonuçlarına göre kanser hücre hatlarında 25-50-100 µg/ml gossipin dozlarının HSP60 ve HSP70 gen ekspresyon seviyeleri üzerinde etkili olduğu bulundu. Gossypin, üç hücre hattında HSP60 ve HSP70'in ekspresyonunu doza bağımlı olarak etkilemiştir. Üç hücre hattında, 50 µg/ml ve 100 µg/ml gossipin dozları, HSP60 ve HSP70'in ekspresyonunu kontrol grubuna kıyasla önemli ölçüde azalttı.
Sonuç: Sonuçlarımız, farklı hücre dizilerinde çeşitli dozlarda gossypinin antikarsinojenik etkisini güçlü bir şekilde desteklemektedir. Fakat, daha fazla in vivo araştırma ve insan çalışmalarına ihtiyaç olduğuna inanıyoruz. Bulgularımız, gossypin'nin farklı kanser türlerinin önlenmesi ve/veya tedavisi için yeni stratejiler geliştirmek için daha ileri araştırmalar için uygun aday ajan olabileceğini düşündürmektedir.

Abstract
Cancer has been an insurmountable problem in the history of medical science. The uncontrollable proliferation of cancer cells is one of cancer’s main characteristics, which is closely associated with abnormal mitosis. Targeting mitosis is an effective method for cancer treatment. This review summarizes several natural products with anti-tumor effects related to mitosis, focusing on targeting microtubulin, inducing DNA damage, and modulating mitosis-associated kinases. Furthermore, the main disadvantages of several typical compounds, including drug resistance, toxicity to non-tumor tissues, and poor aqueous solubility and pharmacokinetic properties, are also discussed, together with strategies to address them. Improved understanding of cancer cell mitosis and natural products may pave the way to drug development for the treatment of cancer.

Abstract
MicroRNAs (miRNAs) are involved in cancer progression via translational degradation in a sequence-specific manner of the 3'-untranslated region (3'UTR) of messenger RNA (mRNA). The involvement of miRNA in the biological progression of various cancer types is considered to be a potential target. Primary miRNA (pri-miRNA) and precursor-miRNA (pre-miRNA) synthesize the miRNA by dicer-catalyzed processes thus targeting pri/pre-miRNA by phytochemicals is amongst the appropriate approaches for anticancer therapies. Flavonoids category of phytochemicals is well-known for its chemotherapeutic and chemopreventive potential against multiple cancer types. However, the molecular interactions of flavonoids with miRNAs are not reported so far. Thus, this study aims to identify the promising flavonoids as the antagonist of miRNAs (pre-miR21, pri-miR-208a, pri-miR-378a, pri-miR320b, pri-miR-300, pri-miR-19b, and pre-miR-20b) using molecular docking simulations studies. Among the tested flavonoids, narirutin showed highest binding energy (-11.7 kcal/mol) against pri-miR19b followed by pri-miR-378a (-11.4 kcal/mol) > pri-miR320b (-11.2 kcal/mol) = pri-miR-300 (-11.2 kcal/mol) > pri-miR-208a (-9.0 kcal/mol) > pre-miR-20b (- 8.3 kcal/mol). The molecular dynamic simulation experiment confirmed that narirutin destabilizes the tertiary structure of pri-miRNA in comparison to apo-RNA. The finding indicates that narirutin binding with pre-miRNA causes disruption of pri-RNA structure that creates a loss of DICER-pre-miRNA interactions by hindering the pre-miRNA synthesis, thereby affecting miRNA processing. Further pharmacokinetics and toxicity prediction revealed that it is non-carcinogenic, non-mutagenic, and does not inhibit the CYPs activity. Thus, narirutin could be a possible antagonist of oncogenic miRNAs, therefore could be useful for miRNA-targeted cancer prevention and treatment.

Abstract
The aim of the study was to examine the protective effects and possible mechanism of gossypin against isoproterenol (ISO)-mediated myocardial damage in vivo and H9c2 cell damage in vitro. H9c2 cells were categorized into five groups. Viability was evaluated with MTT and LDH release in H9c2 cells. Apoptotic parameter analysis was performed with cytochrome c (Cyt-c), caspase-3 (CASP-3), and BCL2/Bax mRNA expression levels. In vivo, gossypin was administered orally to mice at doses of 5, 10, and 20 mg/kg for 7 days. ISO groups were injected with isoproterenol (150 mg/kg) subcutaneously (on 8th and 9th) for 2 days. Afterward, lactate dehydrogenase (LDH), creatine kinase-MB (CK-MB) levels and Troponin-I (Tn-I) amount from their serum, oxidative stress parameters superoxide dismutase (SOD) activity, glutathione (GSH) and malondialdehyde (MDA) levels, and tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1 β), and NF-kB mRNA expression levels with inflammatory markers from heart tissue were evaluated. In addition, IL-1B, BCL-2, and cas-3 immunohistochemical staining was performed from heart tissue and TNF-a level was measured by ELISA method. Administration of Gossypin protected the cells by dose-dependent, eliminating the reduced cell viability and increased LDH release of ISO in H9c2 cells. In mice serum analyses, increased LDH, CK-MB levels, and Tn-I levels were normalized by gossypin. ISO administration in heart tissue is regulated by gossypin with increased SOD activity, GSH amount, TNF-α, IL-6, IL-1β, and NF-kB mRNA expression levels and decreased MDA amount. Overall, the present results demonstrated that gossypin has a potential cardioprotective treatment for ischemic heart disease on in vivo and in vitro.

Abstract
Abstract: An imbalance of angiogenesis contributes to many pathologies such as cancer, arthritis and retinopathy, hence molecules that can modulate angiogenesis are of considerable therapeutic importance. Despite many reports on the promising antiangiogenic properties of naturally occurring flavonoids, no flavonoids have progressed to the clinic for this application. This systematic review and meta-analysis therefore evaluates the antiangiogenic activities of a wide range of flavonoids and is presented in two sections. The first part of the study (Systematic overview) included 402 articles identified by searching articles published before May 2020 using ScienceDirect, PubMed and Web of Science databases. From this initial search, different classes of flavonoids with antiangiogenic activities, related pathologies and use of in vitro and/or in/ex vivo angiogenesis assays were identified. In the second part (Meta-analysis), 25 studies concerning the antiangiogenic evaluation of flavonoids using the in vivo chick chorioallantoic membrane (CAM) assay were included, following a targeted search on articles published prior to June 2020. Meta-analysis of 15 out of the 25 eligible studies showed concentration dependent antiangiogenic activity of six compared subclasses of flavonoids with isoflavones, flavonols and flavones being the most active (64 to 80% reduction of blood vessels at 100 µM). Furthermore, the key structural features required for the antiangiogenic activity of flavonoids were derived from the pooled data in a structure activity relationship (SAR) study. All in all, flavonoids are promising candidates for the development of antiangiogenic agents, however further investigations are needed to determine the key structural features responsible for their activity.

Lapachol is a novel ribosomal protein S6 kinase 2 inhibitor that suppresses growth and induces intrinsic apoptosis in esophageal squamous cell carcinoma cells. Phytother Res 2019; 33:2337-2346.

Abstract
Lapachol is a 1,4-naphthoquinone that is isolated from the Bignoniaceae family. It has been reported to exert anti-inflammatory, antibacterial, and anticancer activities. However, the anticancer activity of lapachol and its molecular mechanisms against esophageal squamous cell carcinoma (ESCC) cells have not been fully investigated. Herein, we report that lapachol is a novel ribosomal protein S6 kinase 2 (RSK2) inhibitor that suppresses growth and induces intrinsic apoptosis in ESCC cells. We found that lapachol strongly attenuates downstream signaling molecules of RSK2 in ESCC cells and also directly inhibits RSK2 activity in vitro. The RSK protein is highly activated in ESCC cells and knockdown of RSK2 significantly suppresses anchorage-dependent and anchorage-independent growth of ESCC cells. Additionally, lapachol inhibits anchorage-dependent and anchorage-independent growth of ESCC cells, and the inhibition of cell growth by lapachol is dependent on the expression of RSK2. We also found that lapachol induces mitochondria-mediated cellular apoptosis by activating caspases-3, -7, and PARP, inducing the expression of cytochrome c and BAX by inhibiting downstream molecules of RSK2. Overall, lapachol is a potent RSK2 inhibitor that might be used for chemotherapy against ESCC.
