Scientists are advancing cancer treatments after cracking IKAROS code

While scientists have been on the hunt for potential and infections meeting several breakthroughs along the way. Recently, researchers from Monash University in Australia cracked the code behind IKAROS and made another stride by discovering the underlying mechanisms of this protein. This protein is essential for immune cell development and its role in protecting against pathogens and cancer.

Deciphering IKAROS IKAROS is an essential protein for immune cell development and protection against pathogens and cancer, according to a by the scientists. Scientists uncovered how blocking the transcription factor – Ikaros/Ikzf1 affected the activity of Natural Killer (NK) cells, resulting in dysregulation of their development and function.

This impacted their ability to identify and eliminate virus infected and metastatic tumor cells. Additionally, they found that related family members of the protein –Aiolos/Ikzf3 and Helios/Ikzf2 partially compensated for the loss of Ikaros. However, the statement noted that when multiple IKZF family members were inhibited, NK cells underwent rapid death.

In terms of mechanism, researchers observed that Aiolos and Ikaros directly interacted with and triggered the activation of a majority of the JUN/FOS family. These proteins are known as transcription factors. They form a part of the activator protein 1 (AP 1) complex. JUN/FOS family of proteins play key roles in regulating gene expression and controlling various cellular processes like growth, differentiation, and responses to external stimuli.

Furthermore, they are recognized transcription factors critical in human embryo development and tissue function. Potential novel cancer therapeutics The statement noted that this discovery opens the door to potential novel cancer therapeutics. “NK cells, our first line of defense against pathogens and internal threats like cancers, could be fortified by therapies enhancing their killing prowess by targeting IKAROS and JUN/FOS biology.” Professor Nicholas Huntington of Monash University’s Biomedicine Discovery Institute remarked that drugs targeting IKAROS/AIOLOS have already received approval from the US Food and Drug Administration (FDA) and local Therapeutic Goods Administration (TGA).

These drugs will aim to treat B cell malignancy. He added, “But until now, we haven’t understood how these drugs work, armed with this new information, it could be possible to develop novel drugs targeting these complexes, which may offer differentiated pharmacology and therapeutic index for treating disease.” The team of scientists investigating the demonstrated that IKAROS plays a conserved function in the health of B cells, suggesting its potential significance in B cell cancers.
