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.

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.

Paracrine Effect

The therapeutic potential of the dental pulp stem (DSC) cell-derived secretome, consisting of various biomolecules, is undergoing intense research. Despite promising in vitro and in vivo studies, most DSC secretome-based therapies have not been implemented in human medicine because the paracrine effect of the bioactive factors secreted by human dental pulp stem cells (hDPSCs) and human exfoliated deciduous teeth (SHEDs) is not completely understood. In this review, we outline the current data on the hDPSC- and SHED-derived secretome as a potential candidate in the regeneration of bone, cartilage, and nerve tissue. Published reports demonstrate that the dental MSC-derived secretome/conditional medium may be effective in treating neurodegenerative diseases, neural injuries, cartilage defects, and repairing bone by regulating neuroprotective, anti-inflammatory, antiapoptotic, and angiogenic processes through secretome paracrine mechanisms. Dental MSC-secretomes, similarly to the bone marrow MSC-secretome activate molecular and cellular mechanisms, which determine the effectiveness of cell-free therapy. Many reports emphasize that dental MSC-derived secretomes have potential application in tissue-regenerating therapy due to their multidirectional paracrine effect observed in the therapy of many different injured tissues.

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.

323 Background: Adiponectin is the key adipokine, which plays an important role in health and disease such as obesity, diabetes, and cancer. Adiponectin is reduced in different tumor types, especially in obesity-related cancer, and recent studies showed that Adiponectin had a potential anti-cancer effect. Obesity is a risk factor for various tumor diseases including cholangiocarcinoma (CC), the second most common primary hepatic cancer. The aim of this study is to investigate for the first time the anti-cancer effect of AdipoR agonist in CC cell lines and a CC engineered mouse model. Methods: Human CC cell lines (TFK-1 and SZ-1) and CC engineered mice (Alb-Cre/KRASG12D/p53L/L) were used to investigate the anti-cancer effects of an AdipoR agonist (2-(4-Benzoylphenoxy)-N-[1-(phenylmethyl)-4-piperidinyl]-acetamide). Cell proliferation, migration, invasion, colony formation, apoptosis assay were applied to evaluate the effect of AdipoR agonist in vitro. In addition, important cancer signalling pathways and targets were analysed by Western Blot. Mice (n = 12) were treated with AdipoR or verhicle and tumor burden and survival were monitored. Results: AdipoR agonist suppressed proliferation, migration, invasion, colony formation and apoptosis in CC cells. AdipoR agonist regulated the expression of different proteins such as EMT markers, pAMPK, pSTAT3, and PARP, which have pivotal functions in cholangiocarcinogenesis. AdipoR agonist also prolonged survival time in a CC engineered mouse model. Conclusions: Our data revealed that AdipoR agonist inhibited successfully cell proliferation, migration, invasion, colony formation and apoptosis in vitro, and prolonged mice survival in vivo through regulation of crucial signaling pathways in cholangiocarcinogenesis. These results suggested that AdipoR agonist might become a new potential candidate for CC treatment in the future.
