Features:
Cisplatin is a chemotherapy medication used to treat various types of cancer. It is a platinum-based drug that works by interfering with the DNA of cancer cells, preventing them from reproducing and ultimately leading to cell death.
Cisplatin (cis-diamminedichloroplatinum II; CDDP) is a platinum-based chemotherapeutic agent that forms covalent DNA crosslinks, primarily intrastrand adducts at adjacent guanine bases. These distort DNA structure, block replication and transcription, and activate DNA damage response pathways (ATM/ATR → p53), leading to cell-cycle arrest and apoptosis. Secondary mechanisms include ROS generation, stress MAPK activation, and modulation of NF-κB. Clinical resistance frequently involves enhanced DNA repair (ERCC1/NER), altered drug transport (CTR1, ATP7A/B), and increased antioxidant defenses. Major toxicities include nephrotoxicity, ototoxicity, and peripheral neuropathy.

Rank Pathway / Axis Cancer / Tumor Context Normal Tissue Context TSF Primary Effect Notes / Interpretation
1 DNA crosslink formation (intrastrand adducts) DNA adducts ↑; replication block ↑ Normal dividing cells also affected P, R, G Direct DNA cytotoxicity Cisplatin forms covalent intrastrand crosslinks (primarily at adjacent guanines), distorting DNA and blocking replication and transcription.
2 DNA damage response (ATM / ATR → p53) Checkpoint activation ↑; p53 signaling ↑ ↔ (toxicity in proliferating tissues) R, G Damage signaling cascade DNA distortion activates ATM/ATR pathways leading to p53-mediated cell-cycle arrest and apoptosis.
3 Intrinsic apoptosis (mitochondrial pathway) Bax ↑; Bcl-2 ↓; caspase-9/3 ↑ Nephrotoxicity & ototoxicity risk G Execution of cell death Persistent DNA damage triggers mitochondrial outer membrane permeabilization and caspase activation.
4 Cell-cycle arrest (G2/M emphasis) G2/M arrest ↑ ↔ G Cytostasis → apoptosis Cells accumulate in G2/M phase due to unrepaired DNA lesions.
5 ROS generation / oxidative stress ROS ↑ (secondary mechanism) Oxidative injury ↑ (kidney, cochlea) R, G Stress amplification Cisplatin increases mitochondrial ROS and oxidative stress, contributing to cytotoxicity and organ toxicity.
6 MAPK signaling (JNK / p38 activation) Stress MAPK activation ↑ ↔ R, G Stress-response signaling JNK and p38 activation contribute to apoptosis and stress signaling.
7 NF-κB activation (resistance axis) NF-κB ↑ may promote survival ↔ R, G Resistance modulation NF-κB activation can reduce sensitivity; inhibition enhances cytotoxicity in some models.
8 DNA repair pathways (NER / ERCC1) NER ↑ → resistance — G Resistance determinant Nucleotide excision repair (ERCC1) removes platinum adducts; high ERCC1 correlates with resistance.
9 Drug transport (CTR1 uptake; ATP7A/B efflux) CTR1 ↓ or ATP7A/B ↑ → resistance — G Exposure constraint Copper transporters influence intracellular cisplatin accumulation and resistance.
10 Clinical toxicity profile — Nephrotoxicity, ototoxicity, neurotoxicity — Translation constraint Major dose-limiting toxicities arise from DNA damage and oxidative stress in normal tissues.

Time-Scale Flag (TSF): P / R / G

  • P: 0–30 min (DNA aquation and initial adduct formation)
  • R: 30 min–3 hr (checkpoint activation / stress signaling)
  • G: >3 hr (apoptosis, phenotype outcomes, resistance development)

Type: Antiapoptotic Oncogene
The proteins of BCL-2 family are classified into three subgroups, i.e., the anti-apoptotic/pro-survival proteins represented by BCL-2 and BCL-XL, the pro-apoptotic proteins represented by BAX and Bak, and the pro-apoptotic BH3-only proteins represented by BAD and BID.
Since the expression of Bcl-2 protein in tumor cells is much higher than that in normal cells, inhibitors targeting it have little effect on normal cells.
