By using a laser microbeam technology called optical tweezers, UC Irvine and UCLA researchers have uncovered fundamental properties of a key molecular signaling system involved with development, cancer and cardiovascular disease. In collaboration, UCI's Elliot Botvinick and UCLA's Gerry Weinmaster published online in the journal Developmental Cell complementary studies in which they each used optical tweezers to detect and measure the mechanical force produced by cells when bound to Notch, a cellular pathway that ensures the correct cell types form at a precise time and location in the body.
