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:

β-Hydroxybutyrate - Beta-Hydroxybutyrate / 3-Hydroxybutyrate

Abbreviation: BHB, β-HB,β-HOB

Type: Ketone body / metabolic and signaling metabolite

Function: β-Hydroxybutyrate is a major circulating ketone body produced primarily by the liver during fasting, carbohydrate restriction, prolonged exercise, or ketogenic metabolism. It serves as an alternative mitochondrial energy substrate and also functions as a signaling metabolite that can regulate NLRP3 inflammasome activity, histone deacetylase activity, oxidative stress, mitochondrial function, gene expression, and inflammatory responses.

Cancer: ↕ Context-dependent. β-Hydroxybutyrate can inhibit inflammatory and growth-related signaling and has demonstrated anti-proliferative and anti-migratory effects in some experimental cancer models. However, metabolic utilization of ketone bodies varies among cancers, and some tumor cells can use β-hydroxybutyrate as an energy or biosynthetic substrate.

Alzheimer's Disease: ↑ Generally neuroprotective. β-Hydroxybutyrate provides an alternative energy substrate when cerebral glucose metabolism is impaired and can inhibit NLRP3 inflammasome activation, reduce microglial neuroinflammation, improve mitochondrial function, and reduce oxidative stress. Experimental studies support beneficial effects on cognition and Alzheimer's-related pathology.
