Research Description: 

During cell division, sister chromatids must be divided equally into two daughter cells to maintain genome stability. In order to achieve accurate chromosome segregation, microtubules need to be properly assembled at a specific chromosome site that is called the kinetochore. A kinetochore is a macromolecular protein complex on centromeric chromatin which contains critical epigenetic marks. Improper microtubule-kinetochore attachment causes aneuploidy, micronuclei, and numerous developmental diseases.  These disorders demonstrate how understanding the mechanisms underlying faithful chromosome segregation is important for various fields of study.

Aneuploidy is particularly important, as ~90% of solid tumors show aneuploidy. However, it remains unclear how cells achieve accurate chromosome segregation, what causes aneuploidy, and how chromosomal instability (including aneuploidy) contributes to carcinogenesis and cancer progression.

Our lab focuses on discovering the molecular mechanisms underlying force production, mitotic checkpoint control, and error correction in accurate cell division, with a focus on the role of the highly conserved Ndc80 complex. We recently developed a FRET (fluorescent resonance energy transfer)-based Ndc80 tension biosensor, which allows us to measure cellular tension using light microscopy. Using this tension biosensor, we will elucidate the mechanisms of how kinetochores produce and transmit force for accurate chromosome segregation. In addition, we are committed to understanding how the loss of centromere/kinetochore integrity causes carcinogenesis and cancer progression. We recently found that the CENP-H/I complex, which is a member of core-kinetochore proteins, is overexpressed in primary colon cancer and its expression levels inversely correlate with the stage of cancer progression. We are investigating the functions of CENP-H/I complex in cancer. In order to reveal centromere/kinetochore functions, our lab uses advanced light and electron microscopy techniques. Our techniques include quantitative confocal microscopy to measure cellular protein copy number, light-sheet microscopy for high spatial/temporal live cell imaging, various super-resolution microscopes (SIM/STORM/STED) for nm-scale analysis, FRET-based tension biosensor, FRAP/TIRF system for cellular protein dynamics, and immuno-electron microscopy.
