14 Obesity genes discovered

  • The epidemic of Obesity is driven by high-calorie diets, sedentary lifestyles & genes that regulate the metabolism (fat storage & catabolism)
  • Hundreds of genes associated with obesity have been identified by the geneticists, that are prevalent in obese people than in people with a healthy weight.
  • O’Rourke and her collaborators used the obesity model of C. elegans worms that share more than 70% of our genes to screen 293 genes associated with obesity in humans with aim of identifying which of the genes have pro & anti-obesity effects.
  • Automation and supervised machine learning-assisted testing were used to identify 14 genes pro-obesity genes & 2 anti-obesity genes. Further research also proved that blocking one of the 14 genes in lab mice prevented weight gain, improved insulin sensitivity.
  • Genomics-based combination therapy is the future for many diseases including obesity however more research has to be conducted to design a proven therapy.
