Medical researcher's discovery may explain how certain cancers develop

28.05.2010
A Florida State University College of Medicine researcher has discovered a new interaction between a cell signaling system and a specific gene that may be the cause of B-cell lymphoma. The finding suggests a similar interaction could be occurring during the development of other types of cancer, leading to further understanding of how cancer works — and how it might be stopped.

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.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
