The first gene-edited birds – scientists are trying to fix our chickens

There are no wild chickens. It is an animal that humans pretty much invented by breeding wild fowls. And we continue improving our chickens until they have all of our desired characteristics. There are more chickens in the world than any other bird and it is incredibly important for us […]

New CRISPR-Cas9 variant may boost precision in gene editing

Researchers have developed a new variant of the gene editing technique CRISPR-Cas9 that has the potential to increase precision during gene therapy in humans. The new variant reduced unintended changes in DNA compared to its wildtype, suggesting it could play a role in gene therapies that require high precision. The […]

Surgical Innovation Course Fosters New Approach to Bone Healing

Within minutes of breaking a bone, the body begins to repair itself. The immune system sends in cells that act as housekeepers, sweeping out small bone pieces and killing germs. The body forms a soft protective callus to bridge the fracture and blood vessels that grow into the area to […]

Map showing gene interactions could lead to new cancer therapies

Nearly 150,000 cancer-related deaths can be attributed annually to Epstein-Barr (EBV) virus, in part because of the lack of effective treatment options. Now, a research team has created the first comprehensive map of interactions between the genes of the virus and host cells in EBV-associated cancers, knowledge that could lead […]

Gene Therapy Update: Remembering Jesse Gelsinger

Like the mythological phoenix bird, gene therapy has risen from the ashes and is spreading its wings. September 17 marked 20 years since the death of 19-year-old Jesse Gelsinger in a gene therapy trial. That tragedy halted the fledgling field, with the outlook worsening when, soon after, boys with an […]

Immunologists identify T cell homing beacons for lungs

Scientists have identified a pair of molecules critical for T cells, part of the immune system, to travel to and populate the lungs. A potential application could be strengthening vaccines against respiratory pathogens such as influenza. The findings were published online in Journal of Experimental Medicine. Much research on immunity […]

Study finds age may hinder cancer development

A new study, published in Aging Cell, has found that human ageing processes may hinder cancer development. Ageing is one of the biggest risk factor for cancer. However, the biological mechanisms behind this link are still unclear. Each cell in the human body is specialised to carry out certain tasks and […]

U of A researchers move closer to ‘magic’ cancer treatment

Imagine cancer treatment without chemotherapy, radiation or surgery. Just a small aspirin-like pill. Sound like magic? That’s because it kind of is, according to Khaled Barakat, a University of Alberta biophysicist searching for innovative immunotherapies that could help knock out multiple types of cancer simply by empowering the immune system. “We […]

Spotlighting a common female cancer, and a health disparity

Most women now know to how to check for breast cancer.  And a yearly pap smear to check for cervical cancer is de rigueur.  But awareness of endometrial cancer, not so much. That bothers Dr. Kemi Doll, a gynecologic oncologist with the University of Washington School of Medicine. “The truth is, this is […]

Patients could stop breathing for a while to make radiation therapy more accurate

Radiation therapy can be a very effective way to treat cancer – tumour are zapped with a very accurate and very sharp beam of radiation. However, despite the machines being incredibly precise, the treatment might be compromised by the patient’s movement. Now scientists from the University of Birmingham demonstrated that […]

Scientists found a way to reactivate ‘tumour suppressor’ genes

You would get cancer all the time, if your body was not ready to react and suppress the starting disease. Immune system recognizes young cancer cells and kills them. Then there are tumour fighting genes, which stop cancer cells from dividing and spreading. Sadly, cancer is a sneaky disease, able […]

Healthy organelles, healthy cells

For a long time, the contents of cells were thought to be fairly unstructured and chaotic: a mixture of proteins, DNA and a multitude of small metabolic molecules. Although important cellular processes in plants and animals were known to take place in organelles (larger structures enclosed by a membrane, such […]
