CircTET2 overexpression activated the mechanistic target of rapamycin complex 1 (mTORC1) pathway and elevated the levels of carnitine palmitoyl transferase 1A (CPT1A) and carnitine palmitoyl transferase 1B (CPT1B), which in turn promoted the growth of CLL cells91. This evidence concerns the gene CPT1A and B-cell chronic lymphocytic leukemia.
