Relationship among miRNA, TP53 and TERT levels in 13q14del chronic lymphocytic leukemia. (A, B) Relationship between TERT and TP53 levels in: (A) 13q14del CLL, (B) CLL with no chromosomal abnormalities. (C-F) Relationship between percentage of deleted nuclei and levels of (C) miR-15a, (D) miR-16-1, (E) TP53, (F) TERT. (G) Proposed network among miR-15a/miR-16-1, TP53, and TERT expression. Down-regulation of miR-15a/miR-16-1, due to 13q14 deletion, leads to increased TP53 levels which, in turn, down-regulate levels of TERT, the catalytic component of the telomerase complex.
