HPV has been implicated in many cancers to be found in diverse place throughout the human organism. How is the RNAi derived?

"Milner said she intended starting clinical trials as a potential treatment for cervical cancer within five years."

Five years? I'm sure there are plenty of cancer patients who would be willing to volunteer to try it now for a chance at having a normal life span.

As the findings were released on Thursday, it emerged that another team of researchers were planning the world's first clinical trial of the technique, this time on a group of Aids patients. The trial is expected to begin within the next two years.

I'm so sorry but, I suspect there are many loved ones out here that should not have to line up behind those in the aids line. I suspect there are many good descent loved ones that could start a line of their own. AND GUESS WHAT THEY EARNED THE OPPORTUNITY

Now folks don't give me a lesson on aids. Trust me I don't need it and I heard all the crap and balogna from the left liberal gay community.

I believe my 3 yr. old daughter is going to grow up in a world in which cancer is as feared as the common cold.

Exceptional!
I hope and pray it is an effective cancer fighter,
and I hope and pray they make trillions of dollars saving millions of lives,
and I hope and pray that the FDA is overrun by desperate family members screaming for a chance at a cure.

Surprisingly, RNAi could be induced in C. elegans even by ingestion of dsRNA! E. coli expressing dsRNAs for unc-22 or fem-1 were fed to worms, 40-80% of the worms showed the specific phenotypes.

Ohhhhh. Should make it easy to drugify.

There have been many tantalizingly effective anti-cancer drugs that work only in a petri dish. The real problem is how to deliver these agents to where they can be effective.

Let's pray this is one that succeeds.

Holy smoke. I heard of this idea but I didn't think it would work. Holy jumpin' mackerel!

This is, of course, only in vitro, where a number of things seem to work that end up killing the patient in vivo. But it is very promising. That it is a mechanism for apoptosis as well as gene suppression is even more exciting - there are a number of apoptosis-activators currently in clinical trials but I don't know of any that sound this promising. Oncology isn't a magazine known for hype or journalistic hysteria, either.

For those who care, the reason AIDS patients are in this is that they are a conveniently immune-suppressed population that is willing to act as human guinea pigs. I don't care how they got that way, I'm just glad they're volunteering. That is always the most difficult hurdle for treatments involving gross somatic effects, getting something approximating the human organism to act as a disease model for toxicity studies and projected dosages. Unless I'm missing something pretty big this is not a cure for AIDS, it's a potential cure for tumor cancers.

If it was so remarkable why wasn't it published in Science, Nature or New England Journal of Medicine?

Oncogene? Maybe a great journal, but first time I've ever heard of it.

Great news! I think God would be rejoicing that someone had used their skills to a full potential!

The technique, called RNA interference (RNAi), completely eliminated all the cancer cells growing in a test tube yet left healthy cells unharmed. The scientists called the results "absolutely remarkable".

Actually, the technique is called siRNA for 'short interfering RNA'. This short interference RNA itself is a naturally-occurring defence mechanism:
RNA silencing is a eukaryotic genome defence system that involves processing of double-stranded RNA (dsRNA) into 21-26 nt, short interfering RNA (siRNA). The siRNA mediates suppression of genes corresponding to the dsRNA through targeted RNA degradation. In some plant systems there are additional silencing processes, involving systemic spread of silencing and RNA-directed methylation/transcriptional suppression of homologous genomic DNA.
--EMBO J 2002 Sep 2;21(17):4671-4679
Two classes of short interfering RNA in RNA silencing.
Hamilton A, Voinnet O, Chappell L, Baulcombe D.
So, once again, we have an example of the benefits of molecular biology's exploitation of nature.

The work left to be done to get something from an in-vitro research tool to an effective therapeutic modality is "absolutely staggering". We're only at the very beginning of the beginning.

Here is the abstract of the paper in question:
Selective silencing of mammalian gene expression has recently been achieved using short interfering RNA (siRNA). Synthetic siRNA targets homologous mRNA for degradation and the process is highly efficient. Here we demonstrate siRNA silencing of pathogenic viral gene expression. As a well characterized model we chose cervical carcinoma cells positive for human papillomavirus type 16. Over 90% of human cervical cancers are positive for papillomavirus and abnormal cell proliferation is driven by co-operative effects of viral E6 and E7 genes. We sought to silence HPV E6 and E7 gene expression using siRNAs to target the respective viral mRNAs. Our results indicate selective degradation of E6 and E7 mRNAs. Silencing was sustained for at least 4 days following a single dose of siRNA. E6 silencing induced accumulation of cellular p53 protein, transactivation of the cell cycle control p21 gene and reduced cell growth. In contrast, E7 silencing induced apoptotic cell death. HPV-negative cells appeared unaffected by the anti-viral siRNAs. Thus we demonstrate for the first time (i) that siRNA can induce selective silencing of exogenous viral genes in mammalian cells, and (ii) that the process of siRNA interference does not interfere with the recovery of cellular regulatory systems previously inhibited by viral gene expression.

Milner said she intended starting clinical trials as a potential treatment for cervical cancer within five years. Cervical cancer is the second-most-common form of female cancer, killing 1 250 British women a year.

wHY WAIT SO LONG. aND WHY START TESTS ON aids PATIENTS??? Sheesh, Cancer should have been cured years ago if not for billions of dollars being diverted to save Magic Johnson's et al life.
