Extract of sample "How to Treat Breast Cancer With Turmeric"

In spite of reaching the very zenith of both technological and medical research, humans have failed to solve health problems such as cancer which continues to claim lives all around the world. Instances of breast cancer is prevalent among women and rising rapidly. However, epidemiological studies have shown that in Countries such as India and other south East Asian countries , the rates of breast cancer occurrence is far below the rates of their counterparts in the Western World. Thorough studies had been conducted to understand the exact reason for this discrepancy. The reason has been traced to nutritional intake. In spite of the nutritional intake of the Oriental world being far lower than the Western world in terms of calories and other health supplements, the presence of spices such as turmeric and other rhizomes have a drastic effect on the health. Turmeric, has long been used as a medicine in traditional Ayurveda and is today considered a potential candidate for treating cancer naturally. In this experiment, cucurmin, the active chemical derived from turmeric and known to have inhibitory effect on cancer cells, will be used to treat breast cancer cell lines in different concentrations. The results will be recorded and analyzed to understand the positive effects of in taking turmeric on a daily basis and the most effective concentration of cucurmin. CONTENTS Topic Page Introduction 3 Samples and Methods 5 Assay 5 Timeline 6 Outcomes and Implication 7 References Appendix Introduction Breast cancer is one of the leading forms of cancer responsible for high rates of mortality and morbidity among the patients especially women (CDC, 2008). Breast cancer is the most common forms of cancers responsible for deaths among women (Key et al, 2011). In 2012, in the U.K. alone almost 11,643 females and 73 males died from invasive breast cancer. Breast cancer is defines by the uncontrolled growth of the cells present in the breast area. In some cases they enter the blood stream and become invasive by affecting other organs as well. Being diagnosed with breast cancer not only reduces a person’s life span but also diminishes the quality of life that a person leads. Today, medical science has advancements such as surgery, radiotherapy, chemotherapy, hormonal therapy and gene therapy to help fight against cancer but each one of these has severe side effects (Sinha et al, 2012). Ayurveda, the study of using plants for treatment is today regarded as one of the oldest and concrete forms of treatment. In traditional India Ayurveda, people have used Cucurma longa or turmeric to treat inflammations. Besides being used for treating diseases and infections, the gold colored spice is also employed for food preservation and as a natural dye for textile (Aggarwal et al, 2007). The root of the turmeric plant is sued as a spice in many Asian cooking. The efficacy of using turmeric to treat tumorous growth has been research extensively all of which have yielded positive results. Turmeric primarily consists of three different cucurminoids- curcumin demethoxycurcumin, and bisdemethoxycurcumin out of which cucurmin is known to have inhibitory effects on cancer (Jurenka,2009). The chemotherapeutic effect of cucurmin which is a derivative of turmeric and responsible for turmeric’s yellow color, has been reported extensively (Wright et al, 2013). Cucurmin is chemically called 1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione and is known to have antioxidant, antiproliferative and apoptotic properties (Liu and Chen, 2013). Studies on rodents showed that cucurmin alone or in combination in with other chemotherapeutic agents could inhibit tumor growth (Kunnumakkara et al, 2008). Rat model experiments have shown that the rhizome of the spice inhibited cell growth in Chinese hamster Ovary cells and was cytotoxic to lymphocytes as well as Dalton’slymphoma cells at a concentration of 4 µg/ml (Kuttan et al, 1985). Therefore it was concluded that turmeric has the potential to prevent tumor growth in animal models. In another study by Banerjee et al, it was recorded that cucurmin arrested the cell division at G2/M and induced apoptosis. It also inhibited proliferation of cells and activated mitotic checkpoints (Banerjee et al, 2010). Specific breast cancer cell line studies have also shown that cucurmin had an anti-cancer activity. Hassan and Daghestani conducted an investigated to see the effect cucurmin had on the matric metalloproteinases (MMPs) and its regulator, tissue inhibitor metalloproteinases (TIMPs). The results showed that cucurmin inhibited cancer by down regulating TIMP1 and TIMP4 and up regulating MMP-2 and MMP-9 (Hassan and Daghestani,2012). It was not only animal models which responded positively, in-vitro cell line experiments using human cell line cultures have also been studied thoroughly. Some studies have shown turmeric could affect cancer growth of cells by regulating genes. In an investigation sing MCF-10A and MCF-7 it was seen that cucurmin could upregulated 22 genes (HIAP1, CRAF1, TRAF6, CASP1, CASP2, CASP3, CASP4, HPRT, GADD45, MCL-1, NIP1, BCL2L2, TRAP3, GSTP1, DAXX, PIG11, UBC, PIG3, PCNA, CDC10, JNK1 and RBP2.) and downregulated 17 genes (TRAIL, TNFR, AP13, IGFBP3, SARP3, PKB, IGFBP, CASP7, CASP9, TNFSF6, TRICK2A, CAS, TRAIL-R2, RATS1, hTRIP, TNFb and TNFRSF5). The regulation of the genes caused apoptosis in the cancer cells thereby making cucurmin a potential chemopreventive agent (Ramachandran et al, 2005). Various other studies have shown cucurmin acting by regulating genes in order to inhibit cancer. Chen et al, conducted an investigation to determine the molecular targets of cucurmin on lung cancer and established that cucurmin had the potential to inhibit invasion of cancer and prohibit migration of the cells i.e. the process of metastasis making cucurmin a potential candidate for metastatic cancer therapy (Chen et al, 2008). The primary aim of the proposed experimental study is to understand if turmeric has an effect on breast cancer cells. The study also aims to analyze and determine the lowest concentration at which the active substance of turmeric is most effective and induced apoptosis in the tumour cells Samples and Methods. The rationale for the experiment is conducting an in vitro investigation using human breast carcinoma cell lines. The cell lines that shall be employed for the experimental studies are the MCF-7 carcinoma cell lines. The active ingredient that according to research studies have anti-cancer effects on the carcinoma cells is cucurmin and hence cucurmin extracts will be used for the investigation under laboratory conditions. In order to investigate both the cytotoxic and apoptotic effects of cucrmin extract on the selected breast carcinoma cell line. The prime objective of the study is to show the inhibitory effect of turmeric on breast cancer cells in a dose dependent and time dependent manner.The cells will be cultured separately. One of the dishes will serve as the Control, to ensure proper growth of the culture and the others will the experimental dish cultures. Cucurmin will be extracted from turmeric or purchased. After the culture shave been successfully established. 7 dishes will be seeded with 500 viable cells each from the breast cancer cell line.1 of the dishes serves as the control while the others are experimental. The dishes will be incubated at different concentrations of cucurmin ranging from 10µM to 60 µM. for about 12-24 hours. The cells will then be prepared for analysis. Assay Different assays will be conducted to analyse the results. MTT assay will be conducted to obtain the growth inhibition ratio while using flow cytometry we will see the apoptotic activity. Timeline: The time and duration of each of the task of the project is displayed in the Gantt chart below. Outcomes / implications: Thorough research of the possible positive effect of turmeric on cancer has yielded good results. Considering that the efficacy of turmeric in inhibiting cancer is high, it is expected that the experimental approach designed and adopted will yield positive results as well. It is further expected that apoptotic activity will be recorded in the breast cancer cells and the concentration at which the chemical supplement is most effective can be obtained. The success of this experiment will be enough to provide sound evidence of the positive effects of using oriental spices such as turmeric in the western cuisine as well, since turmeric will work naturally without causing negative health effects. This may initiate women in U.K, to either ropt for turmeric supplements or introduce usage of turmeric in their daily meals. References: Aggarwal,B.B.,Sundaram,C., Malani,N., and ichikawa,H. 2007.
