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:

MFN1, MFN2, and OPA1 are mostly AD / neurodegeneration-relevant pathway targets: In AD, the general pattern is: fusion proteins MFN1, MFN2, and OPA1 tend to be reduced or functionally impaired, while fission signaling such as DRP1/FIS1 is often increased, contributing to fragmented mitochondria, synaptic injury, oxidative stress, and impaired bioenergetics

MFN1, MFN2, and OPA1 are mitochondrial fusion regulators. MFN1 and MFN2 mediate outer mitochondrial membrane fusion, while OPA1 mediates inner mitochondrial membrane fusion and helps maintain cristae structure. In Alzheimer’s disease and related neurodegenerative models, mitochondrial dynamics are commonly shifted toward excessive fragmentation, with reduced or impaired fusion signaling and increased fission stress. Restoring MFN2/OPA1/MFN1 activity may help preserve mitochondrial network integrity, oxidative phosphorylation, neuronal transport, calcium handling, and synaptic resilience.

Target / Pathway Primary Disease Relevance Normal Function Observed / Suspected Change in AD Therapeutic Direction Database Interpretation Evidence Strength Notes for Product Screening
MFN1 Mostly AD / neurodegeneration; secondary cancer relevance Outer mitochondrial membrane fusion protein. Works with MFN2 to tether and fuse adjacent mitochondria, helping maintain mitochondrial network integrity and mitochondrial DNA/protein complementation. Generally reported as reduced or functionally impaired in AD-related mitochondrial dynamics imbalance, contributing to mitochondrial fragmentation and reduced neuronal bioenergetic resilience. Support / restore mitochondrial fusion where excessive fission and mitochondrial fragmentation are present. Pathway target rather than product. Useful as part of a broader “mitochondrial fusion support” or “anti-fragmentation” pathway entry. Moderate Track products that increase MFN1 expression, improve mitochondrial network morphology, reduce DRP1-driven fragmentation, or restore fusion/fission balance.
MFN2 Strong AD / neurodegeneration relevance; also cancer and metabolic relevance Outer mitochondrial membrane fusion protein. Also involved in mitochondria-ER contact regulation, calcium handling, mitophagy-related quality control, mitochondrial trafficking, and cellular stress adaptation. MFN2 dysfunction or downregulation is associated with impaired mitochondrial fusion, abnormal mitochondria-ER communication, calcium stress, oxidative stress, synaptic vulnerability, and possibly amyloid/tau-associated mitochondrial injury. Usually upmodulation / restoration is desirable in AD models where mitochondrial fragmentation, poor transport, or excessive fission is present. High-priority AD target. Best entered as a mitochondrial dynamics, fusion, ER-mitochondria contact, and mitophagy-quality-control target. Moderate-Strong Track products that increase MFN2, improve mitochondrial elongation, reduce Aβ/tau-induced mitochondrial fragmentation, improve calcium homeostasis, or restore mitochondrial transport in neurons.
OPA1 Strong AD / neurodegeneration relevance; also apoptosis and cancer relevance Inner mitochondrial membrane fusion protein. Maintains cristae structure, supports oxidative phosphorylation, preserves mitochondrial membrane organization, and helps regulate cytochrome-c release during apoptosis. OPA1 loss or cleavage can reduce inner membrane fusion, destabilize cristae, impair oxidative phosphorylation, increase mitochondrial fragmentation, and sensitize neurons to synaptic and metabolic stress. Support / stabilize OPA1 activity, especially long-form fusion-active OPA1, where mitochondrial stress causes excessive OPA1 cleavage and fragmentation. High-priority AD target. Best entered under mitochondrial fusion, cristae integrity, oxidative phosphorylation, and apoptosis-resistance pathways. Moderate-Strong Track products that preserve OPA1, reduce pathological OPA1 cleavage, improve cristae integrity, improve ATP production, or reduce mitochondrial apoptosis signaling.
