Scientists at The University of Nottingham have found that a genetic rogue element produced by sequences until recently considered “junk DNA” could promote cancer progression.
The researchers, led by Dr Cristina Tufarelli, in the School of Graduate Entry Medicine and Health Sciences, discovered that the presence of this faulty genetic element — known as chimeric transcript LCT13 — is associated with the switching off of a known tumor suppressor gene (known as TFPI-2) whose expression is required to prevent cancer invasion and metastasis. Their findings suggest that LCT13 may be involved in switching off TFPI-2.
