Virus passed through chickens

Scientists eventually learned that src makes a type of protein called a kinase. Kinases are enzymes — proteins that speed up chemical reactions. This sticking-on of phosphates is called phosphorylation. Kinases help control growth and reproduction in cells, among other behaviors. Normally, they are active for a time, then the cell switches them off. The mutant version of the src gene, found in RSV, makes a kinase that is essentially on all the time, like a gas pedal stuck to the floor.

Resh says. Getting infected with RSV is one way to acquire this mischievous oncogene. Since src was discovered, scientists have found numerous other oncogenes in cells. Many, like src , encode protein kinases. In their normal form, they are referred to as proto-oncogenes; in their mutated cancer-causing form, they are called oncogenes. Knowing which genes and proteins are malfunctioning to cause cancer opens the door to targeted therapies directed at these bad actors.

Src was the first oncogene identified and also the first tyrosine protein kinase, making it a good drug target. Chickens are also a good cancer model because their telomeres are regulated like ours.

However, the recent supply chain disruption, thanks to the rumours about the virus, have precipitated a fourfold hike in poultry production costs relative to returns. As a result, the livelihoods of the nearly 20 million people dependent on the national poultry industry have been severely and adversely hit.

At this point, you might like to know that chicken do harbour coronavirus — as do Japanese quails and even ducks. But this is only part of the full picture. The entire Coronaviridae family is classified into four subdivisions , or genera, called Alpha -, Beta -, Gamma — and Deltacoronavirus.
