Once considered genomic “junk,” repetitive sequences in DNA are being discovered to have important roles in our biology. Whitehead Institute researchers are investigating different types of these repeated sequences, from repetitive DNA regions to excessive repeats within genes, in order to understand what roles they play in cells and how they contribute to health and disease.

Climate change and economic development are increasing our risk of being infected by parasites and harmful viruses and bacteria. Whitehead Institute researchers are leveraging their expertise to better assess where pathogens will spread and evaluate their risk to humans.

Whitehead Institute researchers have uncovered a molecular mechanism underlying type 2 diabetes. The new finding reveals that insulin receptors, the signaling molecules that sense insulin, normally function by clustering together in cells and that this clustering is defective in insulin resistance, the basis of type 2 diabetes. The researchers hope that this work will bring about a better understanding of diabetes at a molecular level and lead to the development of new therapies.

Marine Krzisch is a postdoc in Whitehead Institute Member Rudolf Jaenisch’s lab who works on making better models with which to study neurological diseases. We sat down with Marine to learn more about her and her experiences in and out of the lab.
