Normal body cells multiply in a controlled manner and undergo apoptosis when the body no longer needs them. Different types of cancers exist, and the common ones include breast, cervical, prostate, lung, colon, and skin cancers. Several factors have been associated with cancers, and these factors include poor dieting, exposure to harmful chemicals and radiation, weak immune system, and genetics. Cancer presents an enormous health threat in the modern world and thus the need to identify an effective treatment. The conventional treatments used in the management of cancer include chemotherapy and physiotherapy. These forms of cancer treatments usually have enormous side effects on the subjects. In this respect, an alternative form of treatment would be effective in managing cancer patients. A substantial number of natural products have been observed to be effective in the management of cancer. These natural products include plants and other natural substances such as honey. This study focuses on the efficiency of natural products in the treatment of cancer. Also, the anticancer effects of Peganum harmala, Manuka honey, and Saudi honey will be analyzed. Bee honey and Peganum harmala have been traditionally used in the treatment of cancer. The extracts from Peganum harmala plant have also been shown to exhibit divers’ antitumor effects similar to the mode of action of a vast number of anticancer agents. These established hypotheses thus give the rationale for this study. In this experiment, extracts were obtained from Peganum harmala leaves and exposed to cervical, lung, and prostate cancer cells. Similarly, solutions of Manuka honey and Saudi honey were exposed to the cervical, lung, and prostate cancer cells. The experiment duration was 24 hours, which obtained results were recorded and analyzed. Peganum harmala extracts inhibit cancer cell growth at different and achievable concentrations. Manuka honey highly inhibits the growth of HeLa cancer cells while Saudi honey highly inhibits the growth of A549 cells. Peganum harmala can form an effective treatment for managing several types of cancers. Manuka Honey can be applied as an effective treatment for managing cervical cancer while Saudi honey can form an effective treatment for managing lung cancers. 展开更多

Current antitumor monotherapy has many limitations,highlighting the need for novel synergistic anticancer strategies.Ferroptosis is an iron-dependent form of nonapoptotic cell death that plays a pivotal regulatory role in tumorigenesis and treatment.Photodynamic therapy(PDT)causes irreversible chemical damage to target lesions and is widely used in antitumor therapy.However,PDT’s effectiveness is usually hindered by several obstacles,such as hypoxia,excess glutathione(GSH),and tumor resistance.Ferroptosis improves the anticancer efficacy of PDT by increasing oxygen and reactive oxygen species(ROS)or reducing GSH levels,and PDT also enhances ferroptosis induction due to the ROS effect in the tumor microenvironment(TME).Strategies based on nanoparticles(NPs)can subtly exploit the potential synergy of ferroptosis and PDT.This review explores recent advances and current challenges in the landscape of the underlyingmechanisms regulating ferroptosis and PDT,as well as nano delivery system-mediated synergistic anticancer activity.These include polymers,biomimetic materials,metal organic frameworks(MOFs),inorganics,and carrier-free NPs.Finally,we highlight future perspectives of this novel emerging paradigm in targeted cancer therapies. 展开更多

BACKGROUND Reactive oxygen species(ROS)are produced by multiple cellular processes and are maintained at optimal levels in normal cells by endogenous antioxidants.In recent years,the search for potential exogenous antioxidants from dietary sources has gained considerable attention to eliminate excess ROS that is associated with oxidative stress related diseases including cancer.Propolis,a resinous honeybee product,has been shown to have protective effects against oxidative stress and anticancer effects against several types of neoplasms.AIM To investigate the antioxidant and anticancer potential of Lebanese propolis when applied alone or in combination with the promising anticancer compound Thymoquinone(TQ)the main constituent of Nigella sativa essential oil.METHODS Crude extracts of Lebanese propolis collected from two locations,Rashaya and Akkar-Danniyeh,were prepared in methanol and the total phenolic content was determined by Folin–Ciocalteu method.The antioxidant activity was assessed by the ability to scavenge 2,2-diphenyl-1-picrylhydrazyl(DPPH)free radical and to inhibit H2O2-induced oxidative hemolysis of human erythrocytes.The anticancer activity was evaluated by[3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyl tetrazolium bromide]MTT assay against HCT-116 human colorectal cancer cells and MDAMB-231 human breast cancer cells.RESULTS The total phenolic content of propolis extract from Rashaya and Akkar-Danniyeh were 56.81μg and 83.503μg of gallic acid equivalent/mg of propolis,respectively.Both natural agents exhibited strong antioxidant activities as evidenced by their ability to scavenge DPPH free radical and to protect erythrocytes against H2O2-induced hemolysis.They also dose-dependently decreased the viability of both cancer cell lines.The IC50 value of each of propolis extract from Rashaya and Akkar-Danniyeh or TQ was 22.3,61.7,40.44μg/mL for breast cancer cells at 72 h and 33.3,50.9,33.5μg/mL for colorectal cancer cells at the same time point,respectively.Importantly,the inhibitory effects of propolis on DPPH radicals and cancer cell viability were achieved at half its concentration when combined with TQ.CONCLUSION Our results indicate that Lebanese propolis extract has antioxidant and anticancer potential and its combination with TQ could possibly prevent ROS-mediated diseases. 展开更多

Prostate and bladder cancers are the two prevalent urological cancers, and several therapeutic options are currently available but the outcomes have not been satisfactory. To find the better therapeutic option, we investigated if the bioactive extracts of monk fruit, mogrosides, with potential anticancer activity might have anticancer effect against prostate and bladder cancer cells. Four of commercial products made of mogrosides known as Lakanto<sup>ò</sup> (LKT) products, LK1, LK2, LLE, and MOG, were then tested. A dose-dependent study at given concentrations of four products showed that LK1 and LK2 had little effects, while LLE and MOG showed a significant cell viability reduction in both PC-3 and T24 cells. To explore the anticancer mechanism of such products, cell cycle analysis was first performed. Such analysis revealed that LLE and MOG, not LK1 and LK2, led to a G<sub>1</sub> cell cycle arrest. Potential induction of endoplasmic reticulum (ER) stress was next examined because it is known to be linked to a cell cycle arrest. The three key regulators involved in ER stress were all up-regulated with LLE or MOG, indicating induction of ER stress. As ER stress is also known to induce apoptosis, this possibility was tested. The two apoptotic regulators were modulated in a specific manner with LLE or MOG, indicating induction of apoptosis. Lastly, to validate anticancer effect of LLE or MOG, anticancer effect of four chemotherapeutic drugs was also assessed in comparison with that of LLE/MOG. None of drugs had any effects but two products showed significant anticancer effect. In conclusion, two monk fruit products, LLE and MOG, demonstrated anticancer activity against PC-3 and T24 cells, significantly reducing cell viability and ultimately inducing apoptosis. Therefore, these two LKT products with few side effects may have clinical implications in the treatment of urological cancers. 展开更多

Anticancer drugs are one of the most direct means of cancer therapy.However,the various cancer progressions hamper the development and discovery of anticancer drugs.In fact,the mechanical properties of the tumor cytoskeleton are extremely vital for any phase of cancer,especially in tumor invasion and metastasis.However,in the current category of anticancer drugs,the cytoskeleton-targeting drugs are limited and their role in tumor progression is unclear.Here,we present the mechanical characteristics of tumor stiffness that are tightly regulated by the cancer cytoskeleton,including actin filaments and microtubules during tumor initiation,growth and metastasis,and review the natural drugs that target the cancer cytoskeleton.We define cytoskeleton dynamics as target mechanisms for anticancer drugs and summarize the plant,microbial and marine sources of natural products.Furthermore,this paper also provides a material pathway to study active tumor mechanics,and introduces the unique advantages and future application potential of tumor cytoskeleton-targeting drugs in clinical use.The material approaches to active cancer mechanics are supplied in this review.We aim to promote the development of anticancer drugs that target tumor mechanics by using those material approaches and finding their pharmacological application. 展开更多

Anticancer drug preparation by pharmacists is a critical task directly related to medical incidents. This study examined the factors influencing medical errors in chemotherapy, that is, errors by specialist pharmacists (CPh) and pharmacists in other departments (NCPh), by measuring their gaze during the preparation of anticancer drugs. The eye-tracking results showed that the gazing time of NCPh was significantly longer than that of CPh for items such as “preparation of a closed-system device” and “preparation of the syringe” and all preparation times (P < 0.05). The NCPh were not assigned to prepare drugs on a regular basis, indicating their lack of familiarity with the process. There was no significant difference in gaze ratio between CPh and NCPh. This outcome was suggested to be a result of the use of an anticancer drug preparation support system. The results for the pupil diameter variation rate showed that NCPh were significantly more mydriatic in the “mixing injections” category than CPh. However, CPh tended to be more mydriatic in the “checking” category. CPh exhibited a smooth workflow and focused on the important items to be checked. This study showed that the differences in procedure flow and concentration points may lead to errors. Furthermore, the results are of interest from the perspective of medical incident prevention. They will be useful in identifying potential human factors, such as where the pharmacist focuses their attention by measuring eye movements. 展开更多

Cancer is a frightful disease and represents one of the biggest health-care issues for the human race and demands a proactive strategy for cure. Plants are reservoirs for novel chemical entities and provide a promising line for research on cancer. Hitherto, being effective, chemotherapy is accompanied by certain unbearable side effects. Nevertheless,plants and plant derived products is a revolutionizing field as these are Simple, safer, ecofriendly, low-cost, fast, and less toxic as compared with conventional treatment methods.Phytochemicals are selective in their functions and acts specifically on tumor cells without affecting normal cells. Carcinogenesis is complex phenomena that involves many signaling cascades. Phytochemicals are considered suitable candidates for anticancer drug development due to their pleiotropic actions on target events with multiple manners. The research is in progress for developing potential candidates(those can block or slow down the growth of cancer cells without any side effects) from these phytochemicals. Many phytochemicals and their derived analogs have been identified as potential candidates for anticancer therapy. Effort has been made through this comprehensive review to highlight the recent developments and milestones achieved in cancer therapies using phytomolecules with their mechanism of action on nuclear and cellular factors. Furthermore, drugs for cancer treatment and their limitations have also been discussed. 展开更多

Objective:To investigate the anticancer property of marine sediment actinomvceles against two different breast cancer cell lines.Methods:In vitro anticancer activity was carried out against breast(MCF-7 and MDA-MB-231)cancer cell lines.Partial sequences of the 16s rRNA gene,phylogenetic tree construction,multiple sequence analysis and secondary structure analysis were also carried out with the actinomycetes isolates.Results:Of the selected five actinomycete isolates,ACT01 and ACT02 showed the IC_(50)value with(10.13±0.92)and(22.34±5.82)μg/mL concentrations,respectively for MCF-7 cell line at 48 h,but ACT01 showed the minimum(18.54±2.49μg/mL)level of IC_(50)value with MDA-MB-231 cell line.Further,the 16s rRNA partial sequences of ACT01,ACT02,ACT03,ACT04 and ACT05 isolates were also deposited in NCBI data bank with the accession numbers of GQ478246,GQ478247,GQ478248,GQ478249 and GQ478250.respectively.The phylogenetic tree analysis showed that,the isolates of ACT02 and ACT03 were represented in groupⅠandⅢ,respectively,but ACT01 and ACT02 were represented in groupⅡ.The multiple sequence alignment of the actinomycete isolates showed that,the maximum identical conserved regions were identified with the nucleotide regions of 125 to 221st base pairs,65 to 119th base pairs and 55,48 and 31st base pairs.Secondary structure prediction of the 16s rRNA showed that,the maximum free energy was consumed with ACT03 isolate(-45.4 kkal/mol)and the minimum free energy was consumed with ACT04 isolate(-57.6 kkal/mol).Conclusions:The actinomycete isolates of ACT01 and ACT02(GQ478246 and GQ478247)which are isolated from sediment sample can be further used as anticancer agents against breast cancer cell lines. 展开更多

We describe a deep lingual arterial embolization of tongue carcinoma with microcapsuled carboplatinum. Methods: Lingual artery cast specimens from cadavers were microscopically examined, and 78 patients with tongue cancer were recruited and treated with the deep lingual arterial embolization therapy. Results: Microcapsule embolism occurred approximately at the fifth or sixth level of the deep lingual artery branches. The five-year survival rate was 88.5% (69 out of 78), and the ten-year survival rate 52.6% (41 out of 78). Conclusion: The deep lingual arterial embolization of tongue carcinoma with microcapsuled carboplatinum is an effective therapy to treat carcinoma in mid-margin or mid-body of the tongue. 展开更多

Objective:To investigate the anticancer activity of Polyalthia evecta(P.evecta)(Pierre) Finet & Gagnep against human hepatoma cell line(HepG2).Methods:The anticancer activity was based on(a) the cytotoxicity against human hepatoma cells(HepG2) assessed using a neutral red assay and(b) apoptosis induction determined by evaluation of nuclei morphological changes after DAP1 staining.Preliminary phytochemical analysis of the crude extract was assessed by HPLC analysis.Results:The 50% ethanol-water crude leaf extract of P.evecta(EW-L) showed greater potential anticancer activity with high cytotoxicity[IC_(50)=(62.8±7.3)μg/mL]and higher selectivity in HepG2 cells than normal Vero cells[selective index(SI)=7.9].The SI of EW-L was higher than the positive control,melphalan(SI=1.6) and the apoptotic cells(46.4±2.6)%induced by EW-L was higher than the melphalan(41.6±2.1)%(P<0.05).The HPLC chromatogram of the EW-L revealed the presence of various kinds of polyphenolics and flavonoids in it.Conclusions: P.evecta is a potential plant with anticancer activity.The isolation of pure compounds and determination of the bioactivity of individual compounds will be further performed. 展开更多
