Research & Publications
The overall research goal of Dr. Heaphy's laboratory is to further understand the contribution of telomere biology in cancer development and progression.
For a variety of human cancers (e.g., prostate, breast, ovarian, brain, pancreas), new molecular biomarkers are urgently needed for improving risk assessment and for accurate prognostication of the disease to improve upon current prevention and treatment strategies. One molecular marker that may address these clinical problems is tissue-based telomere length measurements.
Telomeres are nucleoprotein complexes that function to protect and stabilize the chromosomal ends by preventing chromosome fusions, masking inappropriate double-strand DNA break damage signals, and inhibiting exonucleolytic degradation. In addition to assessing the translational potential of telomere length measurements, his laboratory is working to elucidate the underlying mechanisms of tumor initiation and progression (e.g., through telomere length alterations), as well as understanding how the interactions between the tumor and its tissue microenvironment may facilitate this process.
