Curcumin has been found to be a potent inhibitor of tumour growth and cell proliferation. This activity is linked to curcumin’s antioxidant effect and free radical scavenging effect (Akram et al‚ 2010). It inhibits cancer development and progression‚ thereby targeting multiple steps to malignancy. It has the ability to act like a blocking agent thereby inhibiting the initiation step of cancer by preventing the activation of carcinogen‚ and also as a suppressing agent thereby inhibiting malignant

classes at the NIH‚ Howard Varmus would be captivated by the partnership that seemed to exist between viruses and cancer. His interests would be further spurred by the introduction of two opposing hypotheses‚ the provirus hypothesis and the virogene-oncogene hypothesis‚ both attempted to describe how RNA viruses interacted with chromosomes of infected cells‚ but had little sound data to back either up. With this information in hand‚ Varmus‚ in the summer of ’69‚ travelled to UC San Francisco where he

INTRODUCTION: characteristics‚ basic properties and medical importance of the virus The human papilloma virus‚ a member of the family Papillomaviridae‚ is an agent that causes Human Papillomavirus infections that affect skin and mucous membranes. This group of viruses includes more than 100 different strains or types and more than 30 of these viruses are sexually transmitted. HPV can infect the genital areas of both women and men and is a virus specific to humans. This includes the vulva in

the first plant that has the resistance gene that we are focusing on. This approach will be applied to other plants that have this resistance gene like tomato. Thus‚ the outcome of the resistance plants would be quantitatively measured and decided before applying it on the field. That would be economically highly effective to reduce the loss of the plant and evaluate productivity. Intellectual Merit: This research depend upon one of the resistance genes that had been found in Arabidopsis‚ which

Abstract The body of Caenorhabditis elegans (C. elegans) are surrounded by a cuticle that is molted four times in development although not all cuticle collagen genes are expressed at once. Mutations in these genes lead to morphological defects such as blister formation in the cuticle. The blister phenotype (Bli) is inherited recessively and develop in the adult stage of C. elegans. Other cuticle collagen mutations‚ such as the uncoordinated (unc)‚ roller (rol) and dumpy (dpy) mutations‚ can suppress

to and control in reponse to ribosomal stress. Oncogenic activation ARF‚ a tumor suppressor‚ negatively regulates MDM2 function. The build-up of MDM2 in the nucleoli is stimulated when the central domain of the MDM2 binds to ARF. The E3 ubiquitin ligase activity of MDM2 is also down-regulated by this interaction [39]. Sudies revealed that ARF levels are heightened as a result of abnormal activation of some oncogenes‚ like E2F-1‚ beta-catenin‚ Myc‚ and Ras. Thus‚ MDM2 is isolated from p53 and the

The uncontrolled growth of cells form a lump called tumour. Once the tumour has become cancerous it can cause problems in the following ways: Spreading into normal tissues nearby Causing pressure on other body structures Spreading to other parts of the body through the Lymphatic system ( The lymphatic system
