PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 123:155219. [PMID: 38056150 DOI: 10.1016/j.phymed.2023.155219] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 11/08/2023] [Accepted: 11/13/2023] [Indexed: 12/08/2023]
Abstract
BACKGROUND Lung cancer is one of the deadliest cancers world-wide and immunotherapy has been considered as a promising therapeutic strategy. Previously, our study found that tannins in Phyllanthus emblica L. (PTF) could inhibit the growth of tumor by activating the immune response in liver cancer, and also exhibited a cytotoxicity on human lung cancer cells A549, H460, H1703 in vitro. OBJECTIVE To explore whether PTF inhibited the growth of lung cancer through its immune-regulating function and to clarify underlying mechanisms. METHODS The induction of immunogenic cell death (ICD) were characterized by calreticulin exposure, extracellular ATP secretion, and High Mobility Group Box 1(HMGB1) release both in vivo using LLC-derived xenograft tumor model and in vitro using both mouse LLC and human A549 cancer cells. RESULTS PTF inhibited lung cancer cells growth and tumorigenesis in vivo/vitro and promoted anti-tumor immune responses. We further found that PTF could induce ICD, which then activated Type I interferon responses and CXCL9/10-mediated chemotaxis. Mechanistically, PTF induced the formation of intracellular protein aggregates and following activation of PERK/ATF4/CHOP-dependent endoplasmic reticulum stress-related ICD. Moreover, PTF improved the antitumor efficacy of cisplatin by inducing ICD both in vitro and in vivo. Finally, we screened out 5 components from PTF, including gallocatechin, gallic acid, methyl gallate, ethyl gallate and ellagic acid, which could induce ICD in vitro and might be considered as the potential antitumor pharmacodynamic substances. CONCLUSION In conclusion, PTF inhibits the growth of lung cancer by triggering ICD and remodeling the tumor microenvironment, suggesting that PTF may have promising prospects as an adjacent immunotherapy for cancers.

Abstract
Imbalances in metal homeostasis have been implicated in the progression and drug response of cancer cells. Understanding these changes will enable identification of new treatment regimes and precision medicine approaches to cancer treatment. In particular, there has been considerable interest in the interplay between copper homeostasis and response to platinum-based chemotherapeutic agents. Here, we have studied differences in the Cu uptake and distributions in the ovarian cancer cell line, A2780, and its cisplatin resistant form, A2780.CisR, by measuring total Cu content and the bioavailable Cu pool. Atomic absorption spectroscopy (AAS) revealed a lower total Cu uptake in A2780.CisR compared to A2780 cells. Conversely, live-cell confocal microscopy studies with the ratiometric Cu(I)-sensitive fluorescent dye, InCCu1, revealed higher relative cellular content of labile Cu in A2780.CisR cells compared with A2780 cells. These results demonstrate that Cu trafficking, homeostasis and speciation are different in the Pt-sensitive and resistant cells and may be associated with the predominance of different phenotypes for A2780 (epithelial) and A2780.CisR (mesenchymal) cells.

Abstract
Phyllanthi Fructus (PF), the edible fruits of Phyllanthus emblica L., serves as an important resource for some health products, foods and drugs due to its high safety and sufficient nutritional value. In recent years, in vivo and in vitro experiments have been conducted to reveal the active components of PF. More than 180 compounds have been isolated and identified from the PF so far, primarily including tannins, phenolic acids, flavonoids, terpenoids, polysaccharides, fatty acids and amino acids. In traditional Chinese medicine (TCM), PF is used to cure several diseases such as bronchitis, asthma, diabetes, peptic ulcer, hepatopathy, leprosy, and jaundice. Consistent with ethnopharmacology, numerous modern studies have demonstrated that the extracts or monomeric compounds derived from PF exhibit various pharmacological effects including anti-oxidation, anti-bacteria, anti-inflammation, anti-tumour, anti-virus, immunity improvement, hypoglycemic and hypolipidemic effects, and multiple organ protective protection. Toxicological studies on PF indicated the absence of any adverse effects even at a high dose after oral administration. Due to strict quality control, these pharmacological activities and the safety of PF greatly improve the development and utilization of products. Our comprehensive review aims to summarize the phytochemistry, pharmacological effects, toxicology, and product development of PF to provide theoretical guidance and new insights for further research on PF in the future.

Abstract
The World Health Organization predicts a 70% increase in cancer incidents in developing nations over the next decade, and it will be the second leading cause of death worldwide. Traditional plant-based medicine systems play an important role against various diseases and provide health care to a large section of the population in developing countries. Indigenous fruits and their bioactive compounds with beneficial effects like antioxidant, antiproliferative, and immunomodulatory are shown to be useful in preventing the incidence of cancer. India is one of the biodiversity regions and is native to numerous flora and fauna in the world. Of the many fruiting trees indigenous to India, Mango (Mangifera indica), Black plum (Eugenia jambolana or Syzygium jambolana), Indian gooseberry (Emblica officinalis or Phyllanthus emblica), kokum (Garcinia indica or Brindonia indica), stone apple or bael (Aegle marmelos), Jackfruit (Artocarpus heterophyllus), Karaunda (Carissa carandas) and Phalsa (Grewia asiatica), Monkey Jackfruit (Artocarpus lakoocha) and Elephant apple (Dillenia indica) have been shown to be beneficial in preventing cancer and in the treatment of cancer in validated preclinical models of study. In this review, efforts are also made to collate the fruits' anticancer effects and the important phytochemicals. Efforts are also made at emphasizing the underlying mechanism/s responsible for the beneficial effects in cancer prevention and treatment. These fruits have been a part of the diet, are non-toxic, and easily acceptable for human application. The plants and some of their phytochemicals possess diverse medicinal properties. The authors propose that future studies should be directed at detailed studies with various preclinical models of study with both composite fruit extract/juice and the individual phytochemicals. Additionally, translational studies should be planned with the highly beneficial, well-investigated and pharmacologically multifactorial amla to understand its usefulness as a cancer preventive in the high-risk population and as a supportive agent in cancer survivors. The outcome of both preclinical and clinical studies will be useful for patients, the healthcare fraternity, pharmaceutical, and agro-based sectors.

Abstract
Indian gooseberry (Emblica officinalis Gaertn or Phyllanthus emblica Linn; family Phyllanthaceae) has a recognized history in Indian traditional medicine (Ayurveda). Various therapeutic properties have been attributed to gooseberry as a dietary supplement. Many parts of the plant (fruits, seed, leaves, root, bark, and flowers) possess various activities and are used to treat a range of diseases. This review focuses on the evidence for the cancer-preventive properties of gooseberry, its extracts, and its principal phytochemicals based on studies In Vitro and In Vivo. Most importantly, in multiple rodent models of cancer, treatment with P. emblica was found to prevent tumor incidence, number, and volume at various organ sites. The mechanism(s) implicated in gooseberry-mediated cancer inhibition are diverse and include antioxidants, Phase I and II enzyme modifications, anti-inflammatory action, regulation of the cell cycle, and modulation of oncogenic signaling genes. Studies in humans also indicate that P. emblica can offer various health benefits and synergize with other treatments. This review provides detailed information on the potential use of gooseberry extract as an anticarcinogenic in humans, illuminates the therapeutic applications, and discusses clinical trials.

Abstract
Epithelial ovarian cancer (EOC), a gynecological tumor, is associated with high mortality. MicroRNAs (miRs) serve a crucial role in EOC; however, the mechanisms underlying the effect of miRNA-193a-5p in EOC are not completely understood. Therefore, the present study aimed to investigate the expression levels of miR-193a-5p in serum samples of patients with EOC and to determine the role of miR-193a-5p in EOC. Reverse transcription-quantitative PCR was used to analyze the expression levels of miR-193a-5p in serum samples of patients with EOC and EOC cell lines. The effects of miR-193a-5p and RB binding protein 6, ubiquitin ligase (RBBP6) on the biological functions of EOC were determined by conducting a series of in vitro cell function experiments. The results indicated that the expression levels of miR-193a-5p were significantly decreased in serum samples obtained from patients with EOC and EOC cell lines compared with healthy individuals and normal cells, respectively. Further investigations indicated that RBBP6 was a target gene of miR-193a-5p. The expression levels of RBBP6 were significantly increased in patients with EOC compared with healthy individuals. In addition, in vitro analysis suggested that miR-193a-5p mimic significantly decreased SKOV3 cell proliferation, migration and invasion, and promoted SKOV3 cell apoptosis compared with the control and mimic-negative control groups. In addition, RBBP6 overexpression reversed miR-193a-5p mimic-mediated effects. In conclusion, the results of the present study suggested that downregulated expression levels of miR-193a-5p may serve an inhibitory role in EOC by inhibiting cell proliferation and metastasis, and promoting apoptosis.
