In those studies, Figure 1 - Cisplatin activation and DNA damage induction. A) The cisplatin activation process occurs by exchange of one or two of its chlorides for water molecules (monoaquated and diaquated, respectively). cisplatin–DNA adducts initiate a series of cellular events, such as blocking DNA replication and gene transcription, triggering diverse signalling pathways. Together, these eﬀects eventually leadtoapoptosisorsystematiccelldeath.2–5 Tocounteractthese eﬀects, DNA repair proteins in the nucleus form a self-defence system against this DNA damage.

The cisplatin molecule binds with a protein on one side and the DNA molecule on the other.

2019-01-18 · Cisplatin interacts with DNA mainly in the form of Pt-d (GpG) di-adduct, which stalls cell proliferation and activates DNA damage response. Although cisplatin shows a broad spectrum of anticancer

Griffioen, Rosario Scopelliti, and Paul J. Dyson. Abstract. The pronounced neurotoxicity of the potent antitumor drug cisplatin frequently results in the onset of peripheral polyneuropathy (PNP), which is assumed to be initially triggered by platination products in the nuclear DNA of affected tissues.

include enhanced DNA repair (16â€”20),alteration in the types of platinum-DNA adducts formed (21, 22), and damage tolerance, which could result from an inability to undergo programmed cell death (23-25). In order to more fully elucidate the multiple mechanisms respon sible for cisplatin resistance, we have established a series of cisplatin

Since Pt-GG does not appear to block DNA replication more than 8-oxo-G in mammalian cells, the cytotoxicity of the drug cisplatin that produces the cisplatin-DNA adduct is likely attributed to other causes, such as inter-strand cisplatin-DNA adducts that are more potent for stalling DNA replication.

There is an option for binding cisplatin-modified DNA (Chao et al., 1991; Nishio et al., 1994). Initially, it was sug-gested that the binding of these proteins might assist in damage recognition and thus promote repair. It is now accepted that spe-cific recognition of DNA–cisplatin adducts by nuclear proteins, especially from the HMG-domain family, inhibits Cisplatin, a DNA-crosslinking agent, is able to suppress DNA synthesis by conforming DNA adducts in cancer cells. Cisplatin , CAS 15663-27-1 Pack Size At high enzyme concentrations (2.5–25-fold excess over primer-template), pol β did not differentiate between cisplatin and oxaliplatin adducts for any DNA substrate tested (data not shown); therefore data are presented for cisplatin-damaged templates only.

For nuclear genomes, cisplatin–DNA adducts are enriched within promoters and regions harboring transcription termination sites. While the density of GG dinucleotides determines the initial crosslinking of cisplatin, binding of proteins to the genome largely contributes to the accumulative pattern of cisplatin–DNA adducts.

Fig. 3 shows the enzyme concentration-dependence and time course for translesion synthesis past cisplatin-GG adducts using all four DNA Then, ICP-MS was used to quantify the formation of intracellular platinum (Pt)–DNA adducts, which is thought to be crucial to the antitumor potency of cisplatin. A marked increase in Pt-DNA adducts was detected in cells after treatment with GOx/TPZ@Lipo-Pt for 7 hours ( Fig. 4H ) ( 38 ).
