MIT scientists just discovered the function of 14-3-3 sigma protein, and also, what happens if it isn’t present in cells. This is a HUGE discovery toward preventative measures in cancer screening technology. It won’t be long before there are a new set of diagnostics out that screeen for a wide range of cancer precursor biomarkers that increase risk of cancer to a give tissue.
So, what do scientists propose that 14-3-3 sigma does? It plays a role in cell division. Specifically, it helps cells finish cytokinesis and separate into two distinct cells, right at the end of cell division. Michael Yaffe, an associate professor of biology and biological engineering and leader of the research team said “The cells try to divide and try to divide, and they just give up. They can’t finish cytokinesis.” This results in a single cell with two nuclei.
