In certain tumors of antibody-producing B lymphocytes, the cyclin D1 gene is translocated & its transcription is

under the control of an antibody-gene enhancer, causing elevated cyclin D1 production.

Because they cannot rotate, each peptide bond holds 6 atoms in a plane.

However, most possible angles of Phi (φ) and Psi (ψ) are impossible due to clashes

between atoms. These balls are much smaller than the atoms they represent.

Camptothecin is an inhibitor of eukaryotic type I topoisomerases.

Irinotecan (Campto) and topotecan (Hycamtin)—used to treat colorectal cancer and ovarian cancer.

All these drug's act by trapping the topoisomerase-DNA complex in which the DNA is cleaved, inhibiting religation.
