Background: Several reviews about phytotherapy and homeopathy have been published in the last years, including Viscum album (VA.L). VA is a parasite plant whose extract has anti-cancer proprieties and is used alone or in combination with conventional chemotherapy. Methods: We performed a systematic review about the in vivo and in vitro models described in the literature, including veterinary clinical trials. The literature was consulted from Pubmed database. Results: There are several kinds of pharmaceutical preparations about VA and their active principles used in experimental studies, lectin being frequently studied (alone or as an extract compound). More than 50% of available literature about VA is related to the lectin effects. On the other hand, the effects of viscotoxins are less studied. Among the in vivo experimental studies about VA and its compounds, the B16 murine melanoma is the most used model, followed by Ehrlich, Walker and Dalton tumors. The results point to the apoptotic effects, metastasis control and tumor regression. Some veterinary clinical studies about the use of VA in the treatment of sarcoid, fibrosarcoma and neuroblastoma are quoted in literature too, with interesting results. Considering the in vitro models, our review revealed that NALM6 leukemia cells, B16 melanoma and NC1-H460 lung carcinoma were the most studied tumor models, apoptosis signals being the most important findings. Only one study verified immunoglobulin and interleukin production. All consulted papers were related to phytotherapy preparations only. Conclusions: Although the literature about the anti-cancer activity of VA extract and its lectins is enough, there is a marked lack of information about viscotoxin activities and about the effects of homeopathic preparations of this plant on animal tumors and on in vitro cultivated tumor cells.

Tumorigenic Activity

Background:Cancer is one of the main causes of death worldwide. Contemporary therapies, including chemo- and radiotherapy, are burdened with severe side effects. Thus, there exists an urgent need to develop therapies that would be less devastating to the patient’s body. Such novel approaches can be based on the anti-tumorigenic activity of particular compounds or may involve sensitizing cells to chemotherapy and radiotherapy or reducing the side-effects of regular treatment.Objective:Natural-derived compounds are becoming more and more popular in cancer research. Examples of such substances are Ursolic Acid (UA) and Oleanolic Acid (OA), plant-derived pentacyclic triterpenoids which possess numerous beneficial properties, including anti-tumorigenic activity.Results:In recent years, ursolic and oleanolic acids have been demonstrated to exert a range of anticancer effects on various types of tumors. These compounds inhibit the viability and proliferation of cancer cells, prevent their migration and metastasis and induce their apoptosis. Both in vitro and in vivo studies indicate that UA and OA are promising anti-cancer agents that can prevent carcinogenesis at each step. Furthermore, cancers at all stages are susceptible to the activity of these compounds. </P><P> Neoplasms that are formed in the gastrointestinal tract, i.e. gastric, colorectal, pancreatic, and liver cancers, are among the most common and most lethal malignancies. Their localization in the digestive system, however, facilitates the action of orally-administered (potential) anti-cancer agents, making chemopreventive drugs more accessible.In this paper, the anti-tumorigenic effect of ursolic and oleanolic acids on gastric, colon, pancreatic, and liver cancers, as well as the mechanisms underlying this process, are presented.

Different diseases and disorders that affect the kidneys include, but are not limited to, glomerulonephritis, diabetic nephropathy, polycystic kidney disease, kidney stones, renal fibrosis, sepsis, and renal cell carcinoma. Kidney disease tends to develop over many years, making it difficult to identify until much later when kidney function is severely impaired and undergoing kidney failure. Although conservative care, symptom management, medication, dialysis, transplantation, and aggressive renal cancer therapy are some of the current strategies/approaches to kidney disease treatment, new preventative targeted therapies are needed. Epidemiological studies have suggested that a diet rich in fruits and vegetables is associated with health benefits including protection against kidney disease and renal cancer. Resveratrol, a polyphenol found in grapes and berries, has been reported to have antioxidant, anti-inflammatory, antidiabetic, hepatoprotective, neuroprotective, and anti-cancer properties. The current review summarizes the existing in vitro and in vivo animal and human studies examining the nephroprotective effects of resveratrol.

The anti-hyperglycemic drug, Metformin, is effective in treating early stages of diabetes and has been associated with a 37% decrease in cancer incidence. While the precise mechanisms for the anti-cancer effects of Metformin remain to be elucidated, this review shows the multiplicity of its effects on interdicting signaling and crosstalk, anti-inflammatory effects and in restoring homeostasis, which, taken together, go beyond its well-known anti-hyperglycemic effect that serves as the basis for its use in type 2 diabetes. Metformin is much more than a one-trick pony. The recent discovery of several signaling pathways influenced by Metformin appears to have potential value in cancer therapy. Based on what we know at present, Metformin promotes beneficial effects attributed to its anti-inflammatory and anti-fibrotic effects largely demonstrated in vitro. Metformin activates or upregulates while it simultaneously inhibits or downregulates multiple signaling pathways of cell-cycle arrest and apoptosis accompanied by oxidative stress, which are in accordance with the 6-step sequence of carcinogenesis. Furthermore, in vivo studies in laboratory animals and in cancer patients are beginning to address the magnitude of the anti-cancer effects and delineate its anti-cancer effects. In this context, results from prior pancreatic and non-pancreatic cancer trials, which contained a significant proportion of the patient population treated with Metformin, will have to be reexamined in light of the observed anti-cancerous effects to gain additional insights. The detailed exploration of Metformin in the context of the “Disruption of signaling homeostasis induced crosstalk in the carcinogenesis paradigm Epistemology of the origin of cancer” can provide helpful insights into the anti-proliferative mechanisms and could play a relevant role in anti-cancer therapy in the future.

Background: Anticancer drug development is a tedious process, requiring several in vitro, in vivo, and clinical studies. To avoid chemical toxicity in animals during an experiment, it is necessary to envisage toxic doses of screened drugs in vivo at different concentrations. Several in vitro and in vivo studies have been reported to discover the management of cancer. Materials and Methods: This study has focused on bringing together a wide range of in vivo and in vitro assay methods, developed to evaluate each hallmark feature of cancer. Result: This review provides elaborated information about target-based and cell-based screening of new anticancer drugs in the molecular targeting period. This would help to incite an alteration from the preclinical screening of pragmatic compound-orientated to target-orientated drug selection. Conclusion: Selection methodologies for finding anticancer activity have importance for tumor-specific agents. In this study, advanced rationalization of the cell-based assay is explored along with broad applications of the cell-based methodologies considering other opportunities also.

In recent decades, cancer has been one of the leading causes of death worldwide. Despite advances in understanding the molecular basis of tumorigenesis, diagnosis, and clinical therapies, the discovery and development of effective drugs is an active and vital field in cancer research. Tetrahydrocurcumin is a major curcuminoid metabolite of curcumin, naturally occurring in turmeric. The interest in tetrahydrocurcumin research is increasing because it is superior to curcumin in its solubility in water, chemical stability, bioavailability, and anti-oxidative activity. Many in vitro and in vivo studies have revealed that tetrahydrocurcumin exerts anti-cancer effects through various mechanisms, including modulation of oxidative stress, xenobiotic detoxification, inflammation, proliferation, metastasis, programmed cell death, and immunity. Despite the pharmacological similarities between tetrahydrocurcumin and curcumin, the structure of tetrahydrocurcumin determines its distinct and specific molecular mechanism, thus making it a potential candidate for the prevention and treatment of cancers. However, the utility of tetrahydrocurcumin is yet to be evaluated as only limited pharmacokinetic and oral bioavailability studies have been performed. This review summarizes research on the anti-cancer properties of tetrahydrocurcumin and describes its mechanisms of action.
