It is the second leading cause of cancer deaths among women. While mutation in the BRCA1 and BRCA2 genes confer risk of developing breast cancer. Insulin-like growth factors (IGFs) IGF-1 and IGF-2 are associated with the development and progression of breast cancer. Curcumin is a polyphenol natural product isolated from the rhizome of Curcuma longa. For centuries, curcumin has been used in medicinal preparations and as a food colorant. In recent years, Curcumin, has been reported to have anticancer and chemoprevention effects on breast cancer. Particularly, curcumin has been recognized as an effective anticancer agent that regulates multiple intracellular signaling pathways. This study is designed to investigate the effect of curcumin on gene targeting metabolism on breast cancer. To achieve this aim we conducted the study on MCF-7 cell lines, and evaluate the cytotoxicity of different concentration of curcumin by MTT assay, RNA extracted from MCF-7 cell lines by Qiagen method and reverse transcriptase to cDNA finally quantification of the expression of genes (IGF-1, IGF-2 and BRCA1) by Real time PCR (RT-PCR). The results showed that different concentration of curcumin make inactivation for genes related to breast cancer (IGF1, IGF2 and BRCA1) and can stop the breast cancer pathway. 16 SALWA MOHAMED et al. Conclusively, breast cancer is among the most common malignant tumors. It is the second leading cause of cancer mortality among women in the world. Curcumin, an active derivative from turmeric, has been investigated to have anticancer and chemoprevention effects on breast cancer.in this study different concentrations of curcumin influence the expression of gene targeting metabolism on breast cancer and make inactivation to it which may lead to stopping the breast cancer pathway. Our data demonstrated that curcumin could be used as the treatment of breast cancer.","PeriodicalId":184675,"journal":{"name":"Journal of Productivity and Development","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131995445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

INTRODUCT: The silk industry depends on the growth of silkworm that depends on body weight increase and the biochemical components accumulation of food like protein, amino acids and enzymes (Eman and Marwa 2017). The plants oils could be used for nutrition silkworm to improve silkworm development and silk production, they are making as antimicrobial activity with no side effects on it (Eman and Marwa 2017, Tabassum and Vidyasagar 2013). They have a nutrition profile as a good source of (vitamins E, niacin, riboflavin, etc.), minerals (potassium, phosphorus, magnesium, calcium, iron, zinc, manganese, selenium, copper, etc.), macronutrients (proteins, carbohydrates, fibers, etc.) and fatty acid (saturated, monosaturated and polyunsaturated). The chemical and nutritional composition have been shown to be significantly decrease the risk of diseases, antioxidation and anti-inflammatory action.

Additionally, to evaluate the effect of chlorpyrifosmethyl resistance on fitness cost of Aphis craccivora. With the completion of the work, the development of resistance to chlorpyrifos-methyl toxicity in Aphis craccivora as a result of insecticide selection pressure. The resistance level was amplified over time by continuing exposure to chlorpyrifos-methyl.The resistance ratio (RR) for the selected strain increased from 22.87-fold for the 1 st generation to 45.11-fold for the 8 th generation and 77.76-fold for the 15 th generation. On other word, the oviposition period of the field strain (11.02 days) was longer as compared to resistant strain (6.54) which was shorter than susceptible strain (10.15).The longevity of the chlorpyrifos-methyl resistant strain was (20.68day) and was longer than susceptible aphids (15.24) but field strain was shorter (16.55day). The fecundity was significantly low in resistant strain of Aphis craccivora. The intrinsic rate of increase (rm) ,the finite rate of increase (λ) and the net reproductive rate (R0) of the resistant strain of Aphis craccivora were significantly decreased comparing by susceptible strain. While, the mean generation time (T) in resistant strain was markedly increased as compared to the susceptible strain of Aphis craccivora. Results indicated that the resistant strain showed high resistance to malathion (27.75-fold) after the 8 th generation, development of resistance increased to 39.94-fold after the15 th generation; and the resistance to imidacloprid was 11.76-fold after the 8 th generation then developed to 15.28-fold after the 15 th generation.
