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:
Autophagy genes, including Atg3, Atg5, Atg6, Atg7, Atg10, Atg12, and Atg17.
Tumor autophagy refers to the process by which cancer cells degrade and recycle cellular components through autophagy, a cellular mechanism that helps maintain homeostasis and respond to stress. Autophagy can have dual roles in cancer, acting as both a tumor suppressor and a promoter, depending on the context.
Authophagy is the process used by cancer cells to “self-eat” to survive. Authophagy can be both good and bad. If authophagy is prolonged this will become a lethal process to cancer. On the other hand, for a short while (e.g. during chemotheraphy, radiotheraphy, etc.) authophagy is used by cancer cells to survive.
For example, Chloroquine is a blocker of autophagy and has been used in a lab setting to dramatically enhance tumor response to radiotherapy, chemotherapy.
