Killing tumors by helping them survive!

 :: Posted by American Biotechnologist on 08-14-2012

To survive, tumors need blood supply to provide them with nutrients and oxygen. To get that supply, cancer cells stimulate new blood vessel growth—a process called tumor angiogenesis. Many attempts have been made to inhibit this process as a means to choke off tumors. But tumor angiogenesis can be sloppy, resulting in immature and malformed blood vessels. Since anti-cancer drugs are carried to tumors by the bloodstream, abnormal blood vessel development also hampers delivery. What if, rather than putting a stop to angiogenesis, we could help tumor blood vessels mature more completely, so tumor-killing therapies could more effectively reach their targets? This counterintuitive concept was proposed several years ago, but researchers lacked a way to do it. Now, in a paper published August 14 in the journal Cancer Cell, Sanford-Burnham researchers found a molecule that promotes the tumor vessel maturation process—a discovery that might provide a method for improving cancer drug delivery.

“Our finding suggests that an ability to regulate this molecule could allow us to solve various problems caused by blood vessel abnormalities, including inefficient drug delivery to tumors,” said Masanobu Komatsu, Ph.D., associate professor at Sanford-Burnham and senior author of the study.

The FUNNIEST Science Video On The Web!

 :: Posted by American Biotechnologist on 04-19-2012

This is by far one of the funniest scientific-genre videos on the web. You simply must watch.

One of my favourite lines from the video is when he explains that hundreds of pounds of beard hair sample is kept at -80C “not for preservation…just because I don’t like the smell!” What’s your favourite part?

New Molecular Tool for Prognosis and Treatment of Brain Tumors

 :: Posted by American Biotechnologist on 01-17-2012

In a paper recently published in BMC Medical Genomics, scientists from Sandra L Rodriguez-Zas’ lab at the University of Illinois have identified a cohort of biomarkers that help predict survivability of patients who are afflicted with the aggressive malignant Glioblastoma multiforme brain tumor. The study also found that survivability varies between different genetic profiles and that factors such as race, gender and therapy may have a significant impact upon the survival and quality of life of individuals afflicted by glioblastoma multiforme.

Now that we’ve finished our series on Proteomics Application Tips, it’s time to reward ourselves with a captivating talk by Professor Danny Hillis on Understanding Cancer Through Proteomics. Yes…he’s preaching to the choir, but it’s still fun to see our cause promoted on the “big screen.” Enjoy!

Worm sperm and other creepy crawlers

For better and for worse, human health depends on a cell’s motility –– the ability to crawl from place to place. In every human body, millions of cells –are crawling around doing mostly good deeds ––– though if any of those crawlers are cancerous, watch out.

“This is not some horrible sci-fi movie come true but, instead, normal cells carrying out their daily duties,” said Florida State University cell biologist Tom Roberts. For 35 years he has studied the mechanical and molecular means by which amorphous single cells purposefully propel themselves throughout the body in amoeboid-like fashion ––absent muscles, bones or brains.
