Small changes in genes (leaky genes) create express highway for evolutionary changes

Posted on June 25, 2011 by rndsync

It’s well known that small changes in the initial conditions cause changes in the long term that are not predictable when it comes to complex systems. There is no complex system that I know of that’s more complex than evolution … Continue reading →

Longer telomeres means longer life but also reduced cancer risk?

Posted on April 3, 2011 by rndsync

Evidence has indicated that there’s an inherited factor that helps determine telomere length and that short telomere length is a risk factor for cancer. No one had every connected the two, until now. Jian Gu, Ph.D., assistant professor in MD … Continue reading →

Telomerase inhibitor PINX1 is a key tumor suppressor

Posted on March 23, 2011 by rndsync

Telomeres are ends of choromosomes. For cell division to start and complete ends of chromosomes are essential. Without these, cell can’t divide any more. Each cell can divide a finite number of times before it’s done. It acts like a … Continue reading →

Anti-malirial drug artensuate alone or combined with other cancer therapy effective in killing cancer cells especially if used in short bursts with drug free periods

Posted on January 9, 2011 by rndsync

Scientists investigating the cancer-fighting properties of artesunate a drug commonly used to treat malaria have found early evidence that combining it with an existing cancer drug has the potential to make each drug more effective than when used alone. The … Continue reading →

Exercise is good for you! AMPK role in cell recycling may explain why AMPK plays an important role in metabolic disorders

Posted on December 24, 2010 by rndsync

AMPK (Adenosine monophosphate – activated protein kinase) is an amazing enzyme. It plays critical role in cellular energy homeostasis – maintaining balance of energy production and consumption in the cell by regulating ATP generation. When the process of autophagy is defective, cells … Continue reading →

Do we differ from Chimpanzees in genetic make up?

Posted on December 17, 2010 by rndsync

The popular answer has been that the difference is tiny and we share 98% of the genome with Chimpanzee. However, it’s important to see where these differences lie even though it’s only 2%. In genetics, even a few 1000 base … Continue reading →

Why chromosomes never tie their shoe laces?

Posted on October 16, 2010 by rndsync

Telomeres the ends of chromosomes act like caps on shoe laces. They prevent the chromosomes and the genes there in, from becoming untied there by degenerating the DNA. They also serve another function. DNA has repair mechanism that continuously checks … Continue reading →
