TVP23C-CDRT4 is a readthrough transcript located on chromosome 17 that functions in cellular senescence regulation through mitochondrial ROS control. Primary Function: TVP23C-CDRT4 plays a critical role in modulating mitochondrial reactive oxygen species (ROS) generation and cellular senescence responses 1. The transcript exhibits semi-extractability properties, suggesting localization to nuclear compartments dissociated from chr17, where it may participate in RNA-centric phase separation and nuclear body organization 2. Mechanism: TVP23C-CDRT4 knockdown reduces mitochondrial ROS production and restores senescence-associated phenotypes, including mitochondrial function and cellular rejuvenation 1. The transcript functions downstream of dehydroacteoside-mediated ROS reduction pathways. Disease Relevance: TVP23C-CDRT4 represents a novel gene fusion detected in adenoid cystic carcinoma (ACC) tissues, where it is highly expressed in approximately 20% of cases examined 3. Clinical Significance: Modulation of TVP23C-CDRT4 expression represents a potential therapeutic target for senescence-related aging and age-associated pathologies through ROS regulation. The identification of this gene fusion in ACC suggests potential relevance for cancer immunotherapy approaches, particularly given ACC's immunosuppressive microenvironment 3.
