Singapore, Singapore, June 03, 2016 –(PR.com)– Qatari scientists have recently discovered that an unmutated specific gene marker tends to indicate better prognosis for patients of metastatic colorectal cancer undergoing certain regiment of targeted therapies.

In a first published report of its kind on the subject, the study found that metastatic colorectal cancer patients with wild-type Kirsten Ras (KRAS) gene will likely have better survival rate upon receiving anti-epithelial growth factor receptors (EGFR) targeted therapy.

Meanwhile, the mutated-type KRAS metastatic colorectal cancer patients receiving anti-vascular endothelial growth factor (VEGF) therapy tend to have poorer survival outcomes, according to authors Kakil Ibrahim Rasul, Hind Elmalik, Mini Satheesh and Prem Chandra from National Center for Cancer Care and Research (NCCCR) in Doha, Qatar.

Following a controversial top-secret meeting last month, a group of scientists have announced that they’re working on synthesizing human genes from scratch. The project, currently titled HGP-Write, has the stated aim of reducing the cost of gene synthesis to “address a number of human health challenges.” As the group explains, that includes growing replacement organs, engineering cancer resistance and building new vaccinations using human cells. But in order for all of that to happen, the scientists may have to also work on developing a blueprint for what a perfect human would look like.

In some ways, the concept is just an extension of current gene editing (CRISPR) techniques that are proving their worth by saving lives. CRISPR has already been used to save the life of a one-year-old girl with a terminal case of drug-resistant leukemia. Other initiatives using the system involve curing hemophilia and HIV, although the latter has proven capable of fighting back against attempts to kill it. This new project, meanwhile, will devote time and resources to examining the ethics and economics of how far we should go with gene editing.

HGP-Write is being led by DNA pioneer George Church, a Harvard biologist who is already working on various projects to tweak humanity. In a profile, Stat revealed that the scientist published a paper in 2014 pushing “de novo synthesis,” the concept of creating perfect genes from scratch. In early 2015, he used CRISPR to implant wooly mammoth DNA into a living Asian elephant as the first step toward bringing extinct animals back from the dead. Which, when you write it down like that, makes him sound like a less plausible version of John Hammond, the fictional creator of Jurassic Park.

The new approach has the potential to open a powerful avenue in cellular manipulation. Whereas DNA editing makes permanent changes to the genome of a cell, the CRISPR-based RNA-targeting approach may allow researchers to make temporary changes that can be adjusted up or down, and with greater specificity and functionality than existing methods for RNA interference.

In a study published today in Science, Feng Zhang and colleagues at the Broad Institute and the McGovern Institute for Brain Research at MIT, along with co-authors Eugene Koonin and his colleagues at the NIH, and Konstantin Severinov of Rutgers University-New Brunswick and Skoltech, report the identification and functional characterization of C2c2, an RNA-guided enzyme capable of targeting and degrading RNA.

The findings reveal that C2c2—the first naturally-occurring CRISPR system that targets only RNA to have been identified, discovered by this collaborative group in October 2015—helps protect bacteria against viral infection. They demonstrate that C2c2 can be programmed to cleave particular RNA sequences in bacterial cells, which would make it an important addition to the molecular biology toolbox.

A group of scientists on Thursday proposed an ambitious project to create a synthetic human genome, or genetic blueprint, in an endeavour that is bound to raise concerns over the extent to which human life can or should be engineered.

The project, which arose from a meeting of scientists last month at Harvard University, aims to build such a synthetic genome and test it in cells in the laboratory within 10 years. The project was unveiled in the journal Science by the experts involved.

A 3D hydrogel biochip, a new way of detecting colorectal cancer in the early stages, has been discovered by the scientists at the Moscow Institute of Physics and Technology. The announcement was made in time for the upcoming conference of the annual American Society of Clinical Oncology.

The 3D hydrogel biochip will be using antibodies to determine the CRC specific glycans that emerge in the earliest stages of cancer, with the hope of improving today’s survival rates. These biochips are 3D cells consisting of a special gel that has molecular probes. Based on reports, the physical feature of the gel is an optimal form for running tests. The Russian scientists were able to develop a method that can calculate the concentration of antibodies-to-glycans in the patient’s blood. This means that combining the biochips into a patient’s blood sample will give the mot precise results.

This lil’ kitty named Sonic is now bionic.

The black-and-white cat, who was surrendered to Denver Animal Shelter over three months ago, had been born with a leg deformity called radial agenesis, according to Meghan Hughes, communications director for Denver Environmental Health.

German researchers on Wednesday presented a Trojan horse method of attacking cancer, sneaking virus impersonators into the human body to unleash an anti-tumour immune offensive.

Tested in only three people so far, the treatment claims to be the latest advance in immunotherapy, which aims to rouse the body’s own immune army against disease.

Made in the lab, this Trojan horse is composed of nanoparticles containing cancer RNA—a form of genetic coding—enclosed by a fatty acid membrane.

Precision medicine’s new friend.

CRISPR gene editing can now target RNA as well as DNA, which could be a way to treat infectious diseases and cancer and track RNA as it moves around cells.
