Stanford's goal: to understand protein folding, protein aggregation, and related diseases.



What are proteins and why do they "fold"? Proteins are biology's workhorses -- its "nanomachines." Before proteins can carry out their biochemical function, they remarkably assemble themselves, or "fold." The process of protein folding, while critical and fundamental to virtually all of biology, remains a mystery. Moreover, perhaps not surprisingly, when proteins do not fold correctly (i.e. "misfold"), there can be serious effects, including many well known diseases, such as Alzheimer's, Mad Cow (BSE), CJD, ALS, and Parkinson's disease.

What does Folding@Home do? Folding@Home is a distributed computing project which studies protein folding, misfolding, aggregation, and related diseases. Stanford uses novel computational methods and large scale distributed computing, to simulate timescales thousands to millions of times longer than previously achieved. This has allowed us to simulate folding for the first time, and to now direct Stanford's approach to examine folding related disease.

There really hasn't been any new news from Stanford this month, however I did run across this article dealing with research that could possibly lead to an Alzheimer's vaccine.

Quote:
AUGUSTA, Ga. An accomplice to the protein that causes plaque buildup in Alzheimers disease is the focus of a potential new treatment, according to research by a Georgia Health Sciences University graduate student.

In Alzheimers, the amyloid protein can accumulate in the brain instead of being eliminated by the bodys natural defenses, nestling between the neurons and forming impassable plaques.

Amyloid and the way it gets there could be targets for a new vaccine.

Vijay was a guest on the Twit Netcast, you can watch the interview here.

Also Vijay announced he just recieved the 2012 Michael and Kate Bárány Award.

Quote:
I have some good news. Due in large part to the work we've done with Folding@home, I've been named the recipient of the 2012 Michael and Kate Bárány Award for Young Investigators from the Biophysical Society for "developing field-defining and field-changing computational methods to produce leading theoretical models for protein and RNA folding." This was just annouced in the Biophysics Society newsletter and their web site hasn't been updated just yet for the 2012 awards.


Stanford also released a new paper this month.

Quote:
One major result is in the area of Alzheimer's Disease (paper #95). It is believed that Alzheimer's Disease results from the misfolding of the Abeta peptide. Understanding how Abeta misfolds could give us some key insights into how to cure Alzheimer's Disease. This paper experimentally tests a key prediction made in an earlier paper (paper #58: "Simulating oligomerization at experimental concentrations and long timescales: A Markov state model approach" by Nicholas W. Kelley, V. Vishal, Grant A. Krafft, and Vijay S. Pande. J. Chem. Phys. 129, 214707 (2008); DOI:10.1063/1.3010881). In this paper, we show experimentally that there appears to be a beta turn in the Abeta as predicted. This leads to a very stable form of misfolded Abeta which could be used as a starting point for a new Alzheimer's therapy. We are heavily pursuing this research direction at the moment.

Researchers at the University of Hertfordshire have developed a new structural model of a protein, which makes it possible to develop more effective drugs to target diseases such as cancer, heart disease and influenza.

Also researchers have found that Age-related brain shrinking is unique to humans

Quote:
As we age, our brains get lighter. By 80, the average human brain has lost 15% of its original weight.

People suffering with age-related dementias, such as Alzheimer's, experience even more shrinkage.

This weight loss is associated with a decline in the delicate finger-like structures of neurons, and in the connections between them.

Stanford has been working on the new v7.1.25 and v7.1.26 clients and have posted a status report.

Quote:
It's been a little while since our last v7 beta release (v7.1.24) and so I wanted to give donors some sense of what's going on. We've been working on internal testing of two releases past the current beta release and fixing bugs along the way. While we could in principle release v7.1.25 to open beta, there are enough todo items that we've decided to hold off a bit until it's a bit cleaner and further along. However, we're not going to hold off forever of course, just long enough for our developers to make some significant progress, especially since doing a release generates a lot of feedback, which takes developers away from coding.

To give some sense of where we are, here's the internal release notes for two recent builds (v7.1.25 and v7.1.26). Note that v7.1.26 is still in progress. Also, the #'s after the comment refer to our bug tracker. We have opened up the bug tracker, so one can see progress directly there on a daily basis if you're interested.



v7.1.26 (still under development):

* Failed upload attempt could cause WU to dump before it was expired. #679.

* Added AMD Radeon HD 6600 Series to GPU white-list.

* Fix failure to restart FAHControl in OSX when 'start minimized'. #649.

* Fixed a socket bug that could cause the loss of the end of a message.

* Build OSX client in 32-bit mode with Intel compiler.



v7.1.25:

* Hide 'Quit on window close' option in OSX.

* Fixed some problems with WU assign time and time offset calculations.

* Detect and ignore invalid assign time from older WS.

* Log computed WS time offset.

* Removed warning from Slot configuration about changing threads mid-run.

* Catch and log error accessing battery info in /sys on Linux

* Fix grayed out name and IP in client add after viewing local client. #640.

* Remove 'RS480 PCI-X Root Port' from GPU whitelist. #635

* Added a few new Radeon HD 6xxx cards.

* Added Nvidia GTX 590 device ID 0x1088 to whitelist.

* Increase Radeon HD 5xxxx and 6xxxx GPU type level by one. #653.

* Don't fail WS connections if all data was recieved even on net error.

* Print IP Address with 'Uploading' message.

* Fixes for OSX minimize and quit bugs. #649 & #659.

* Limit max CPUs per slot to system count. #652.

* Attempt to fix #654.

* Release system resources when querying OSX battery status. #650.

* Don't send 'auth' command from FAHControl if empty. #658.

* Fixed 'slot-add' NULL pointer exception. #666.

* Fixed 'log-updates start' error. #671.

* Fixed FAHClient script parsing bug. #676.

* Show 'Remote Access' tab in advanced mode. #648.

* Don't allow minimizing to sys-tray if it is not there. #670.

* Also print core return code numbers in hex. #677.

* Print times in ISO 8601 format. #664.

* Expire WUs in sending status.

Well it seems we've survived yet another judgement day. While that in itself is good news, it also seems that a discovery has been made in the battle against alzheimer's.

Quote:
No one knows the cause of most cases of Alzheimers, Parkinsons and other neurodegenerative disorders. But researchers have found that certain factors are consistently associated with these debilitating conditions. One is DNA damage by reactive oxygen species, highly destructive molecules usually formed as a byproduct of cellular respiration. Another is the presence of excessive levels of copper and iron in regions of the brain associated with the particular disorder.
