Cancer and Genomic Dark Matter
Forum Chairs
Forum Description
Transposable elements (TEs) make up 50% of the human genome but are referred to as "genomic dark matter" or "junk DNA" and often ignored in genomic medicine - both because they have been presumed to be unimportant and because their high copy number and variability pose unique technical challenges. Neither impediment now seems steadfast. Interest in the human transposable elements and their role in cancer has never been greater, and methods enabling its study are maturing at a fast pace.
Transposable elements directly contribute to cancer through both genetic and epigenetic mechanisms. De novo transposon insertions are known to disrupt important genes and gene regulatory elements and result in tumorigenesis. Epigenetically reactivated transposable elements can become cryptic promoters and enhancers and lead to abnormal gene activities including up-regulating oncogenes. These recent mounting evidences request a full understanding of the contribution of transposable elements to cancer.
On the other hand, transposable elements are a double-edged sword. Recent discoveries reveal that epigenetically reactivated transposable elements can produce cancer specific products including immunogenic antigens and double stranded RNAs, which result in an innate immune response. These findings together with rapid development of immunotherapies open new avenues for cancer treatment.
Forum Summary
The Forbeck Foundation hosted an in-person meeting at the beautiful Asilomar Conference Grounds in Pacific Grove, California. Attendees discussed the emerging views on the role of non-coding genome in cancer, especially the role of transposable elements (TEs). It was the first Forbeck Forum to discuss topics in this specific area and one of the first in-person meetings for many attendees after the long COVID-19 hiatus. The meeting was chaired by Ting Wang, PhD (Washington University School of Medicine) and Kathleen Burns, MD/PhD (Dana Farber Cancer Institute). The meeting attendance included four Forbeck Scholars: Carlos Mendez-Dorantes, PhD; Aguirre De Cubas, PhD; Charles Ishak, PhD; and Zuzana Tothova, MD/PhD, among the 19 speakers. Also attending was Forbeck Foundation Scientific Advisory Board member, Dr. Kimryn Rathmell, MD, PhD (Vanderbilt University).
The Forum was divided into 4 sections, structured to (1) define the relationship between transposable elements and the cancer genome; (2) define the relationship between transposable elements and the cancer epigenome; (3) evaluate the implication of transposable elements in cancer therapy; (4) explore the role of transposable elements in cancer evolution.
Throughout the meeting investigators outlined recent progresses and challenges in the field to understand the “genomic dark matter” in cancer, and rigorously discussed and debated key questions, including: 1) Are changes in TE expression in cancers epiphenomenal or contributory? 2) What are the mechanisms underlying cell autonomous effects of TE expression? 3) How might TE expression impact recognition of tumors by the immune system? 4) How can we best model alterations in TE expression in experimental systems? 5) What types of therapeutics might target TE biology? The presentations and discussions highlighted how TEs directly contribute to cancer through both genetic and epigenetic mechanisms, and how their unique biology shapes the cancer genome and epigenome, and presents unorthodox opportunities to diagnose and treat many types of cancers.
Forum attendees acknowledged the difficulties associated with the study of the contribution of transposable elements in cancer, both conceptually and technically. The lack of appropriate cancer models to study transposable elements, and difficulty in mapping the repetitive genome are two examples of these challenges. Technological improvements, especially third generation sequencing, will likely provide new and innovative ways to investigate transposable elements in cancer.
All the talks and discussions inspired continued discussions among participants beyond the two-day meeting. Everyone enjoyed seeing their colleagues and discussing science in a relaxed and stimulating environment. These interactions also fueled new collaboration. Several meeting participants (Kathy Burns, Ting Wang, Guillaume Bourque, Daniel DeCarvalho, Kate Chiappinelli, Zuzana Tothova) submitted a Mark Foundation Endeavor project as a result of the follow up discussions.
Venue & Travel Information

Pacific Grove, CA 93950
Travel Forms
Travel forms are due 30 days prior to the start of the forum to allow enough time to plan transportation.
To help reduce transportation costs, the Foundation tries to group travelers on shuttle vans rather than providing transportation for single travelers. The times below are not exclusive but represent times that we hope to have shuttles leave the airport.
The Monterey Regional Airport (MRY) is the preferred airport as it is only 20 minutes from the venue.
- Arrival day of the forum at approximately 1:00 PM, 3:00 PM and 5:00 PM
- Departures from the venue at approximately 8:00 AM, 10:00 AM, and 12:00 PM
San Francisco International Airport (SFO) is 2 hours from the venue without traffic. The Foundation tries to prioritize International Flights and situations where flying into SFO is significantly cheaper than connecting to MRY. The times below are for guidance only, and depending on the volume of travelers, we may add an additional shuttle to and from the airport.
- Arrival day of the forum at approximately 3:00 PM
- Departures from the venue at approximately 10:00 AM
Travel Policy
Please familiarize yourself with our policies and procedures for travel. We truly appreciate you taking the time to participate in this forum. As you make your plans, please remember that we are a nonprofit organization dependent on donations and volunteers. We do NOT pay for upgrades, change fees, incurred costs resulting from a flight change, transportation to or from your local (home side) airport, meals or other incidentals.
- Travel Confirmation will be sent out within 1 week of the forum. This will include a hotel confirmation number, if there is one, and airport transfer details. We have to wait until we receive almost everyone’s travel to book airport transfer. Due to frequent airline changes, we wait until the week of the forum to send this out.
- Airport transfer is provided by Foundation staff, volunteers or arranged shuttle at specific times. If you opt to utilize Foundation airport transportation on your travel form, please be patient in receiving this information. We will send it to the week of the forum.
- Speaker agenda is not sent out prior to the forum. It will be provided upon arrival in the forum packet. We do not tell people when they are speaking because we expect everyone to attend all sessions. Sessions are all day Friday and Saturday.
- REMINDER: We do not reimburse for home side airport transfer or incidentals while traveling. We will not honor miscellaneous receipts sent for these expenses.
- Spouses are welcome to come with you at their own cost but are not allowed to attend the forum. Please no children.
