It is unlikely that changes in telomeres are influencing the lifespan of the worm. That is because telomeres only shorten when cells divide. Most of the cells of the worm stop dividing when the worm becomes an adult.
I've always drawn, for example, and I did consider when I was younger, it was either do I become an actor or do I become an animator cartoonist at that point. Do I work at Disneyworld or something and do animated cells or something?
Far from being entirely dependent on exogenous food sources of antioxidants, our cells have their own innate ability to generate antioxidants upon demand.
A fundamental premise in cancer therapy is trying to identify how the metabolism of cancer cells differs from normal tissue. When differences are identified, it often paves the way for treatments that will disrupt the cancer's metabolism while sparing normal tissue.
It is a well-documented fact that guys will not ask for directions. This is a biological thing. This is why it takes several million sperm cells... to locate a female egg, despite the fact that the egg is, relative to them, the size of Wisconsin.
The theologians have recognized that the ideal is the imitation of God. If we be a part of such an organic thing, this thing is God to us, as I am God to the cells that compose me.
Cells will die in minutes to days if they lack their genetic information system. They will not evolve, they will not replicate, and they will not live.
We have 200 trillion cells, and the outcome of each of them is almost 100 percent genetically determined. And that's what our experiment with the first synthetic genome proves, at least in the case of really simple bacteria. It's the interactions of all those separate genetic units that give us the physiology that we see.
We're scientists; we're curious about how nature works, but we're also do-gooders. It's fantastic to think that the same experiments we'd do to understand how information gets into cells could have a practical side to them, too.
Bacteria are single-celled organisms. Bacteria are the model organisms for everything that we know in higher organisms. There are 10 times more bacterial cells in you or on you than human cells.
In my lab, we are always thinking about how cells, bacterial cells, can talk to each other and then organize themselves into enormous groups that function in unison.
We keep thinking that the human is evolving. No, the human has evolved to its extent. What's happening now is the organization of humans: just like cells organize to form people, people are organizing to form humanity.
The development of methods to monitor protein dynamics in cells together with the discovery of specific and general lysosomal inhibitors have resulted in the identification of different classes of cellular proteins, long- and short-lived, and the findings of the differential effects of the inhibitors on these groups.
Reticulocytes are terminally differentiating red blood cells that do not contain lysosome. Therefore, it was postulated that the degradation of hemoglobin in these cells is mediated by a non-lysosomal machinery.
