TCEAL6 (transcription elongation factor A like 6) is an X-linked gene with probable roles in transcriptional regulation and tumor suppression. In cervical cancer, TCEAL6 functions as a tumor suppressor; its overexpression significantly inhibits cell proliferation, migration, and invasion while promoting apoptosis in cervical cancer cell lines 1. TCEAL6 expression is suppressed through a regulatory pathway where the circular RNA hsa_circ_0101119 recruits the protein EIF4A3 to inhibit TCEAL6 transcription, promoting cervical cancer progression 1. Beyond cervical cancer, TCEAL6 has been identified as a hub gene shared between Alzheimer's disease and multiple sclerosis, suggesting involvement in neuroinflammatory and neurodegenerative processes 2. In colorectal cancer, TCEAL6 harbors mutation hotspots in microsatellite-unstable tumors, indicating potential oncogenic alterations 3. Additionally, TCEAL6 functions as a transcription factor regulating collagen genes (COL1A1, COL1A2) during colon adenocarcinoma progression through miRNA-mediated interactions (TCEAL6-miR29B2 axes), affecting patient prognosis 4. These findings suggest TCEAL6 has context-dependent roles in cancer biology and neurodegenerative disease, functioning primarily as a tumor suppressor in cervical cancer while participating in transcriptional networks dysregulated across multiple disease contexts.
