#Sensor technology can improve accuracy of prostate cancer diagnosis, research shows Abstract: New research has shown how a smart sensor chip,
and efficiency of prostate cancer diagnosis. Researchers at the University of Birmingham believe that the novel technology will help improve the process of early stage diagnosis. Glycoprotein molecules,
Because of their essential role in our immune response, they are useful clinical biomarkers for detecting prostate cancer and other diseases.
In doing so, they developed a more accurate and efficient way of diagnosing prostate cancer than the current tests
which rely heavily on antibodies. These antibodies are expensive to produce, subject to degeneration when exposed to environmental changes (such as high temperatures
or UV LIGHT) and more importantly, have a high rate of false-positive readings. Professor Paula Mendes said,
so could feasibly be kept on the shelf of a doctors'surgery anywhere in the world.
Problematically for diagnosis, the protein part of glycoproteins does not always change if the body is diseased.
The findings, published in the journal Chemical science, show how the rate of false readings that come with antibody based diagnosis can be reduced by the smart technology that focuses on the carbohydrate part of the molecule.
the team wanted to identify the presence of disease by detecting a particular glycoprotein which has specific sugars in a specific location in the molecule.
and so we need technology that can discriminate between these subtle differences-where antibodies are not able to."
the sugar part of the prostate cancer glycoprotein is reacted with a custom-designed molecule that contains a boron group at one end (the boron linkage forms a reversible bond to the sugar).
and the only key that will fit is the specific prostate cancer glycoprotein that we're looking for.
"Dr John Fossey added,"It's estimated that one in eight men will suffer from prostate cancer at some point in their life,
so there's a clear need for more accurate diagnosis. By focussing on the sugar, we appear to have hit the'sweet spot'for doing just that.
and collaboration with commercial partners, will open the door to adapting the current technology for other diseases.
Lots of diseases produce specific glycoproteins, so there are a number of possible avenues to improve the accuracy of our diagnoses
which could overcome current shortcomings of low drug efficacy and multi-drug resistance in the treatment of cancer as well as viral and bacterial infections.

High-throughput bioactivity screening did not reveal increased toxicity of the particles when compared to an equivalent mass of metallic silver nanoparticles or silver nitrate solution.
"The researchers used the nanoparticles to attack E coli, a bacterium that causes food poisoning; Pseudomonas aeruginosa, a common disease-causing bacterium;
Ralstonia, a genus of bacteria containing numerous soil-borne pathogen species; and Staphylococcus epidermis, a bacterium that can cause harmful biofilms on plastics-like catheters-in the human body.
The nanoparticles were effective against all the bacteria. The method allows researchers the flexibility to change the nanoparticle recipe in order to target specific microbes.
#Nanospheres shield chemo drugs, safely release high doses in response to tumor secretions Scientists have designed nanoparticles that release drugs in the presence of a class of proteins that enable cancers to metastasize.
so that the very enzymes that make cancers dangerous could instead guide their destruction.""We can start with a small molecule
and build that into a nanoscale carrier that can seek out a tumor and deliver a payload of drug,
The system takes advantage of a class enzymes called matrix metalloproteinases that many cancers make in abundance.
The shell fragments form a ragged mesh that holds the drug molecules near the tumor.
builds on his group's earlier sucess using a similar strategy to mark tumors for both diagnosis and precise surgical removal.
and also toxicity, made for a good attachment point. That means the drug was inactivated as it flowed through the circulatory system until it reached the tumor.
The protection allowed the researchers to safely give a dose 16 times higher than they could with the formulation now used in cancer clinics,
in a test in mice with grafted in fibrosarcoma tumors. In additional preliminary tests, Callmann and colleagues were able to halt the growth of the tumors for a least two weeks,
using a single lower dose of the drug. In mice treated with the nanoparticles coated with peptides that are impervious to MMPS or given saline,
the tumors grew to lethal sizes within that time. Gianneschi says they will broaden their approach to create delivery systems for other diagnostic and therapeutic molecules."
"This kind of platform is not specific to paclitaxel. We'll test this in other models-with other classes of drug and in mice with a cancer that mimics metastatic breast cancer, for example."
"They'll also continue to modify the shell, to provide even greater protection and avoid uptake by organs such as liver, spleen and kidneys,
he said.""We want to open up this therapeutic window."#"##Additional authors include Matthew Thompson in Gianneschi's chemistry research group and Christopher Barback, David Hall and Robert Mattrey in UC San diego's Moores Cancer Center.

These so-called artificial antigen-presenting cells (aapcs) were pioneered by Schneck's lab and have shown promise in activating laboratory animals'immune systems to attack cancer cells.
and"present"them with distinctive proteins called antigens. This process activates the T cells to ward off a virus, bacteria or tumor,
as well as to make more T cells. In a previous study in mice, Schneck's team found that naive T-cells activated more effectively when multiple aapcs bound to different receptors on the cells,
priming the T cells both to battle the target cancer and divide to form more activated cells.
humans with magnetic aapcs bearing antigens from tumors. They then ran the plasma through a magnetic column.
The tumor-fighting T cells bound to aapcs and stuck to the sides of the column,
which relies on other white blood cells called tumor-infiltrating lymphocytes. Those cells are trained already"to fight cancer,
and researchers have shown some success isolating some of the cells from tumors, inducing them to divide,
and then transferring them back into patients. But, Schneck says, not all patients are eligible for this therapy,
because not all have tumor-infiltrating lymphocytes. By contrast, all people have naive T cells, so patients with cancer could potentially benefit from the new approach
whether or not they have tumor-infiltrating lymphocytes.""The aapcs and magnetic column together provide the foundation for simplifying
and streamlining the process of generating tumor-specific T cells for use in immunotherapy, "says Juan carlos Varela, M d.,Ph d,
. a former member of Schneck's laboratory who is now an assistant professor at the Medical University of South carolina.
The researchers found that the technique also worked with a mixture of aapcs bearing multiple antigens,
which they say could help combat the problem of tumors mutating to evade the body's defenses."
"We get multiple shots on the goal, "Schneck says. While the team initially tested the new method only on cancer antigens,
Schneck says it could also potentially work for therapies against chronic infectious diseases, such as HIV. He says that
if further testing goes well, clinical trials of the technique could begin within a year and a half.##

New device offers clues (Nanowerk News) Why do some cancer cells break away from a tumor and travel to distant parts of the body?
A team of oncologists and engineers from the University of Michigan teamed up to help understand this crucial question.
Cancer becomes deadly when it spreads, or metastasizes. Not all cells have the same ability to travel through the body,
The differences in individual cancer cells are a key aspect of how cancer evolves becomes resistant to current therapies or recurs."
"A primary tumor is not what kills patients. Metastases are what kill patients. Understanding which cells are likely to metastasize can help us direct more targeted therapies to patients,
"says co-senior study author Sofia D. Merajver, M d.,Ph d.,scientific director of the breast oncology program at the University of Michigan Comprehensive Cancer Center.
The researchers believe this type of device might some day help doctors understand an individual patient's cancer.
Which cells in this patient's tumor are really causing havoc? Is there a large population of aggressive cells?
Are there specific markers or variants on those individual cells that could be targeted with treatment?"
"This work demonstrates an elegant approach to the study of cancer cell metastasis by combining expertise in engineering
"In this work, extensive studies were performed on cell lines representing various types of cancer. The new device was designed to trace how cells move, sorting individual cells by their movement.
