Yoichi Kato, an assistant professor in the Department of Biomedical Sciences, and his lab team found that the gene — known in scientific shorthand as BCL6 — can inhibit one of the pathways cells use to transmit signals to other cells. Called the Notch signaling pathway, it's an important mechanism for cells to control gene regulation.
"There are very few molecules that we know directly inhibit Notch signaling," Kato said. "So that is why the interaction, and our finding, is very interesting to people in many areas — cancer specialists, neuroscientists, and many others."
Kato's team produced a paper outlining the findings that was published in the journal Developmental Cell, and Kato recently presented the paper at an international conference in Cold Spring Harbor, N.Y., for scientists studying early development of vertebrates.
Kato and his researchers have focused on the Notch signaling pathway's role in vertebrate early development. In their study, they found that when BCL6 inhibits the Notch signaling pathway during the early stages of embryo development, the alignment of the embryo's internal organs is affected, which can lead to a congenital disorder.
However, the Notch signaling pathway, which creates the equivalent of a molecular highway across a cell's membrane, is involved in many types of cell-to-cell interaction, including neuron development, stem cell differentiation and apoptosis (programmed cell death).
The fact that BCL6 regulates the Notch signaling pathway could be important for any cellular process where Notch plays a role, including the formation of many cancers. BCL6 is a gene that, when mutated in certain ways, can lead to several types of B-cell lymphoma. B-cell lymphomas, including both Hodgkin's and non-Hodgkin's lymphomas, occur when B-cells, which produce antibodies to fight infections, mutate and become cancerous.
With more study of the interaction between the Notch signaling pathway and the BCL6 gene, scientists may be able to better understand how these cancers form. Kato and his lab plan to further investigate the interaction's role in neural development, as well as how the interaction could affect stem cell formation.
Kato's research is supported by grants from the National Institute of Child Health and Human Development and the Bankhead-Coley Cancer Research Program.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
