UCR Life Science Study Uncovers Fruit Fly Metamorphosis Trigger

Written by BCI Staff | Fri, Jan 27, 2017

Next week PLOS journal will publish an exciting article featuring a new biological discovery. Scientists at UC Riverside have discovered critical information regarding insect development.

This study uncovers the use of DNA as an organism’s biological clock in sexual development, or metamorphosis in insects. With applications in new cancer treatments, agriculture, human health and potential applications in zoology, this study opens gateways of undiscovered information. This is one exciting example of the potential in research and the intersectionality in life science, molecular biology and biotechnology supplies.


With the aid of the fruit fly, Drosophila melanogaster, Dr. Yamanaka and his team of scientists found that without duplication of cells, the insects continue to produce hormones increasing the size of the nucleus. Flooding the cells with the steroidogenic hormone ecdysone creates an enlarged nucleus filled with the hormones that tell the insect when to develop. The hormone was found to be responsible for activating the exact gene expression required for development. When the insect reaches a critical weight with adequate nutrition, development occurs irreversibly.

Dr. Yamanaka used recent advances in genomic research and tools such as microcentrifuge tubes along with primary and secondary antibodies supplied by biotechnology companies including but not limited to Millipore Sigma and Thermo Fisher Scientific.
