Abstract

Cardiovascular disease and cancer are known to be two of the leading causes of death worldwide as stated by the World Health Organization. Currently, cancer therapies are not as effective as they can be due to the resistance of dormant cancer cells. Fetal cardiomyocytes lose the ability to re-enter the cell cycle as they become adult cardiomyocytes, therefore cardiovascular disease causes damage to the tissue that surrounding cells cannot repair. For this reason, identifying and understanding the quiescent phase of cells is necessary to be able to control how cells are affected by therapies or diseases. The transition between a proliferating and quiescent cell, or G1 and G0 phases, is difficult to measure without markers, so in this project, we integrated fluorescent indicators, or FUCCI systems, into the genomes of three different cell lines: an HT1080 line and 2 MCF7 lines. Ki67 mAG/mCherry 2K7BSD and Ki67 mAG Ki67mCherry 2K7BSD indicators were used to identify cells as red in the G1 phase and green in the S, G2, and M phases. Blue fluorescent protein was used to mark every single living cell blue. This method made it easy to identify cells that were only blue under a lumascope as potentially quiescent. To create the cell lines with indicators, a virus was created, which then inserted genes into another mammalian cell line. Using the lumascope after integrating the indicators, we were able to determine whether the virus was successfully incorporated into the genome of the mammalian cell line.
