Of the many viruses screened, adenovirus 36 has been found to be a strong candidate virus that is associated with obesity, based on evidence in various model systems as well as clinical data. The mechanism of how the adenovirus could lead to obesity is not known and this paper proposes some new insights into how oxidative stress could be a possible mechanism of how adenovirus might lead to obesity. This paper reviews the relevant literature of both the effect of adenovirus on cells' anti-oxidant response and the link between obesity and oxidative stress.

"Concordantly, E1A sensitized cells to the cytotoxic effects of oxidative stress and enhanced the accumulation of reactive oxygen species in response to pro-oxidant challenge. These results demonstrate that expression of E1A impedes the cellular response to oxidative stress, including the induction of ferritin."

Research in Alzheimer disease has recently demonstrated compelling evidence on the importance of oxidative processes in its pathogenesis. Cellular changes show that oxidative stress is an event that precedes the appearance of the hallmark pathologies of the disease, neurofibrillary tangles, and senile plaques.

A viral infection that involves virus invasion, protein synthesis, and virion assembly is typically accompanied by sharp fluctuations in the intracellular levels of metabolites. Under certain conditions, dramatic metabolic shifts can result in various types of cell death. Here, we review different types of adenovirus-induced cell death associated with changes in metabolic profiles of the infected cells.

As evidenced by experimental data, in most cases changes in the metabolome precede cell death rather than represent its consequence. In our previous study, the induction of autophagic cell death was observed following adenovirus-mediated lactate production, acetyl-CoA accumulation, and ATP release, while apoptosis was demonstrated to be modulated by alterations in acetate and asparagine metabolism.

On the other hand, adenovirus-induced ROS production and ATP depletion were demonstrated to play a significant role in the process of necrotic cell death. Interestingly, the accumulation of ceramide compounds was found to contribute to the induction of all the three types of cell death mentioned above. Eventually, the characterization of metabolite analysis could help in uncovering the molecular mechanism of adenovirus-mediated cell death induction and contribute to the development of efficacious oncolytic adenoviral vectors.

Oxidative stress is involved in the pathogenesis of many diseases. Overexpression of antioxidant enzymes by gene therapy may protect tissues from oxidative damage. Because the reactive oxygen species hydrogen peroxide can diffuse across cell membranes, we hypothesized that overexpression of the antioxidant catalase within certain cells might protect neighboring cells.

To test this hypothesis, we transduced retinal pigment epithelial (RPE) cells in vitro and in vivo with adenovirus carrying the catalase gene (Ad.CMV.catalase). After transduction of only a subset of RPE cells in vitro, all cells in the culture were protected from exogenous hydrogen peroxide. Similarly, in vivo, eyes injected with Ad.CMV.catalase had high catalase levels in the RPE, which protected the adjacent

Quantum effect

While in the retina, the nanoparticles are stimulated by visible light entering the eye – and if a quantum dot is stimulated while it is in close proximity to a neural cell, it triggers an action potential in that cell which is interpreted as vision by the brain.

Some bacteria are able to use a process called photosynthesis to convert energy from sunlight into another form of energy they can use to grow. Within the bacteria, structures known as photosystems are responsible for absorbing light and transferring the energy to other molecules.
