Prostate cancer
Clinical / Scientific
Prostate adenocarcinoma is typically androgen- dependent. Genomic drivers include AR, ETS fusions, PTEN/, DNA-repair defects and later lineage plasticity to neuroendocrine disease. Metabolic rewiring includes lipogenesis.
Molecular / histological subtypes
Core Biological Drivers
Androgen receptor
Lineage factor.
PTEN / PI3K
Common suppressor loss.
ETS fusions
TMPRSS2-ERG in many acinar tumours.
HRD / BRCA
Subset with PARP relevance.
Key Pathways
Scientific explanation
AR is a nuclear factor required for most prostate adenocarcinoma growth. Resistance can occur through AR amplification, splice variants, or lineage plasticity.
Scientific explanation
phosphorylates PIP2 to PIP3, recruiting . supports growth, survival, glucose uptake and mTORC1 input. Pathway activation is common via PIK3CA mutation, PTEN loss or -tyrosine- signalling.
Scientific explanation
mTORC1 integrates growth-factor and nutrient signals to drive protein synthesis, lipid synthesis and suppression. It sits downstream of PI3K/AKT and amino-acid sensing.
Scientific explanation
Homologous-recombination defects (BRCA1/2 and related) create dependence on PARP-mediated repair. Mismatch-repair deficiency creates hypermutation and immune visibility.
Scientific explanation
Canonical Wnt signalling stabilizes β-catenin, driving TCF/LEF . APC loss is a classic colorectal initiating event; the pathway also contributes to stemness in several tissues.
Scientific explanation
Aerobic (Warburg metabolism) supports ATP, biomass and redox buffering even when oxygen is available. Hexokinase, PKM2 and lactate export are frequent nodes.
Scientific explanation
De novo lipogenesis, fatty-acid oxidation and lipid uptake are rewired in a tumour-type-specific way, especially in hypoxic, obese-host, or OXPHOS-dependent subsets.
Scientific explanation
family ligands drive endothelial sprouting and vascular permeability, a canonical tumour axis.
Scientific explanation
Epithelial–mesenchymal plasticity, driven by TWIST/SNAIL/ZEB and TGF-β/Wnt/Notch inputs, reduces adhesion and increases motility and stem-like features.
Pathway Convergence
Target → pathway → downstream effect → biological consequence. Shared intersections are mechanistic maps, not protocols.
Growth-factor signalling
Ligand or mutation-driven RTK input feeds PI3K/AKT and mTORC1, supporting anabolic growth. This is a map of signalling, not a treatment protocol.
Energy stress
Energetic stress activates AMPK, which can restrain mTORC1. Biguanides and related tools map onto this axis in models.
Hypoxia to vessels
Low oxygen stabilizes HIF-1α, inducing VEGF and endothelial sprouting. Anti-angiogenic pharmacology intersects this axis but does not erase the tumour ecosystem.
Metabolic Vulnerabilities
Aerobic supports ATP, biomass and acidification even when oxygen is available. Extent varies by tumour and remains a vulnerability hypothesis rather than a uniform target.
De novo lipogenesis is AR-linked in many models.
Tumor Microenvironment
Disordered vasculature creates , HIF-1α stabilization, induction and immune-suppressive adenosine/lactate milieus.
Tumour-associated macrophages and myeloid-derived suppressor cells secrete cytokines that support invasion and blunt cytotoxic T cells.
Metastasis Module
Bone tropism dominates: osteoblastic niches, adhesion and chemokine axes.
Resistance Biology
AR amplification/splice variants, bypass RTKs, and neuroendocrine transdifferentiation.
Cancer Stemness
Wnt, Notch, Hedgehog, ALDH and CD44-associated programmes can mark stem-like fractions with quiescence and therapy tolerance. These markers are not interchangeable across tumour types.
Mechanism-Based Adjunctive Strategies
Compounds appear only where a mechanistic overlap exists for this cancer. Evidence tiers are not equivalent. Nothing here is a treatment recommendation.
Target / Mechanism
Modest complex I inhibition raises AMP:ATP, activating and restraining hepatic and -linked anabolism. Direct antineoplastic efficacy is not established from that pharmacology alone.
Cancer relevance
activation and restraint provide a metabolic rationale in - and -linked tumours. Human data are mixed and do not establish metformin as cancer therapy.
Metabolic adjunctive research context. Convergence: AMPK, mTOR, Glycolysis.
Statins (HMG-CoA reductase inhibitors)
Target / Mechanism
Inhibit HMG-CoA reductase, depleting mevalonate-pathway isoprenoids needed for RAS/RHO prenylation and some sterol-dependent growth programmes. Observational oncology signals are mixed and not a licence to treat cancer with statins.
Cancer relevance
Mevalonate-pathway blockade can affect prenylation of RAS-family GTPases. Observational human signals are mixed and confounding is substantial.
Mevalonate / prenylation mechanistic overlap. Convergence: RAS/RAF, Fatty-acid metabolism.
Target / Mechanism
Azole antifungal; off-target reports include Hedgehog-pathway antagonism and anti-angiogenic endothelial effects in experimental and early clinical settings. Not a licensed antineoplastic.
Cancer relevance
Hedgehog antagonism and anti-angiogenic endothelial reports exist, including early clinical probes. Not a licensed antineoplastic.
Hedgehog / angiogenesis research. Convergence: Hedgehog, Angiogenesis.
Target / Mechanism
uncoupler in cestodes; mammalian models report , Wnt/β-catenin and modulation. Those host-signalling findings are investigational/preclinical.
Cancer relevance
Models report Wnt/β-catenin, and effects. Host signalling findings remain investigational.
Wnt / STAT3 signalling models. Convergence: Wnt/β-catenin, JAK/STAT, mTOR.
Target / Mechanism
Benzimidazole that binds β-. Mammalian disruption, mitotic arrest and related signalling in cancer models are preclinical and are not an approved anticancer use.
Cancer relevance
disruption can trigger mitotic stress and in cell and animal models. This is not an established oncology use.
Experimental antimitotic / microtubule stress. Convergence: Apoptosis, p53.
Curcumin
Target / Mechanism
Polyphenol with promiscuous in-vitro NF-κB, and ROS effects. Bioavailability is poor; dish activity does not establish clinical anticancer efficacy.
Cancer relevance
In-vitro NF-κB/ effects are frequent. Poor bioavailability and absence of robust clinical anticancer efficacy keep this pathway-level.
Inflammatory-signalling dish models. Convergence: NF-κB, JAK/STAT.
Celecoxib
Target / Mechanism
Selective -2 reducing PGE2. Relevant to -associated epithelial neoplasia; cardiovascular risk and lack of broad anticancer approval constrain interpretation.
Cancer relevance
-2/PGE2 biology is relevant in some epithelial neoplasias. Cardiovascular risk and lack of broad anticancer approval apply. Do not equate polyp or biomarker studies with tumour cure.
Inflammation-associated epithelial neoplasia research. Convergence: COX / inflammatory signalling, Angiogenesis.
