    devastating category of cancer which is particularly prevalent in women. According to the recent facts and figures from American Cancer Society about the number of deaths from breast cancer in US in 2013, among all ages, has gone up to 39,620. This portrays a massive number, nevertheless analyzing the mortality trend from 1990-2010, one can grasp the death rate has been decreased to 34%. Consequently, the known reason behind this decline is attributable to the improvements in our health care system in terms

    in uncontrolled cell growth leading to formation of tumors. This was facilitated by expressing the targets of miR-10b—BCL2L11/Bim, TFAP2C/AP-2γ, CDKN1A/p21, and CDKN2A/p16 that regulated controlled cell growth. MiR-10b was therefore responsible for uncontrolled cellular growth by downregulating proapoptotic genes. These miRNAs have been validated to negatively regulate the protein tyrosine phosphatase μ (PTPμ) gene that has been observed to be down regulated in these tumor cells. Inhibition of miR-10b

    The role of autophagy poses as a highly conserved catabolic phenomena where cells undergoing stress develop a cytoplasmic crescent shaped phagophore that matures into an autophagosome. The autophagosome is involved in engulfing damaged organelles and long lived proteins in order to replenish the cellular energy content and building blocks for biosynthesis. The autophagy phenomenon always occurs to maintain the cellular homeostasis. But, under stress there is triggering of this autophagy event beyond

    toddlerhood is rapid and critical to the brain’s ultimate functioning level. The cells that make up the nervous system and most of the brain are neurons. They are responsible for sending messages and information throughout the entire body. As the embryo develops, neurons begin forming in the neural tube, and ultimately branch out to create the foundation of the brain. Neurons differ from other types of body cells because they don’t bond with or touch each other. Instead, they are separated by gaps

    The phylogeny shows the relationship of different CASP genes that code for different Caspase proteins in different eukaryotic organisms. This tree was created using CFLAR as the outgroup; (Dereeper, 2008). CFLAR is naturally the most distantly related gene to the others, however CFLAR is in fact quite similar to CASP8. The proteins they both produce are structurally similar, for instance they both have DED domains; (Stennicke & Salvesen, 2000; Watt et al., 1999). Conversely, the protein CFLAR encodes

    anal verge by interactive with putative host cell surface receptors such as heparin sulfate proteoglycans and alpha-6 integrins. Most studies suggest that HPV16 enters the cell via clathrin-mediated endocytosis (Day, 2003, Bousarghin, 2003, Smith, 2007, Hindmarsh, 2007). Although a few contradictory studies suggest that HPV16 is clathrin and caveolaen independent (Spoden, 2008). The virus then uncoats and delivers its genome of 8 genes to the host cell nucleus to be expressed as autonocmous replicating

    of CD8 response, memory generation, disease progression, and viral escape. Classical models of immune response are based on simple ordinary differential equations involving density or number of invading pathogen and many cell types of immune system. The dynamics of CD8 T cell response thus generally follow a predator prey relationship. Many models of immune response has been developed cite{nowak2000virus,wodarz2007killer} and the role of mathematical models is reviewed in detail cite{perelson2002modelling
