Talking Techniques

In many regions of the world, HPV and its association with cervical cancer is a well-known but rarely considered issue, after the rollout of the HPV vaccine in the late 2000s. However, while this rollout significantly impacted cervical cancer rates where it was implemented, it was not universal and in many areas of the world HPV-induced cervical cancer remains a critical issue.

Cervical cancer is the leading cause of death for people with a cervix living in poverty in low-resource regions and on the continent of Africa, it is estimated that in 2020 as many people with a cervix died of cervical cancer as COVID-19.

In this episode of Talking techniques, supported by Oxford Nanopore, Senior Investigator Michael Dean and Post-baccalaureate Fellow Nicole Rossi, from the NIH’s National Cancer Institute (MD, USA), discuss their research into the relationship between HPV and cervical cancer. Expounding on the points mentioned above, they reveal the tremendous insights into cancer and immunology still to be gained, document the key tools used in their studies and explain how their work can be translated into more effective immunotherapies and treatments for cervical cancer.

The key diagnostic and prognostic information locked away in cell-free nucleic acids (cfNAs) has become increasingly accessible due to developments in genetic and epigenetic profiling techniques. These advances have engendered the rise of liquid biopsy techniques, which capture and analyze cfNAs from samples such as blood, saliva, urine and feces, in diagnostics and basic disease research.

However, challenges remain in the detection and analysis of these nucleic acid fragments, in part due to their low abundance and fragile nature. In this episode, Ayla Maunighan-Peter, Epigenetics Product Specialist at Zymo research (CA, USA), details the utility of these molecules, the challenges associated with their development and implementation of liquid biopsies and their use in both basic research and diagnostic spaces.

For an insight into how cfNAs can be used to identify novel drug targets, impact diagnostics development and be used to help soothe the organ shortage crisis, listen today!
