Multiple myeloma
Clinical / Scientific
Myeloma is a bone-marrow plasma-cell neoplasm with IRF4/MYC programmes, unfolded-protein/proteasome stress, marrow-niche RANKL bone disease, and . Proteasome and immunomodulatory drugs are established; metabolic adjuncts are not replacements.
Core Biological Drivers
Plasma-cell identity / MYC
IRF4-MYC circuitry.
Proteasome stress
High immunoglobulin flux.
Marrow / RANKL
Lytic bone disease.
Key Pathways
Scientific explanation
NF-κB factors link inflammatory cytokines and innate sensors to survival, production and sometimes therapy resistance.
Scientific explanation
MYC factors coordinate biomass accumulation, ribosome biogenesis, and glutamine use. Amplification or pathway activation is common.
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
BCL-2, BCL-XL, MCL-1 and BAX/BAK control outer-membrane permeabilization, a core checkpoint frequently skewed toward survival in lymphoid and solid tumours.
Scientific explanation
recycles organelles and can support survival under nutrient or therapy stress. Context determines tumour-suppressive versus therapy-protective roles.
Scientific explanation
family ligands drive endothelial sprouting and vascular permeability, a canonical tumour axis.
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
Folate-methionine cycles supply nucleotides and methylation. Some tumours show methionine dependence and PHGDH or SHMT rewiring.
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.
Inflammatory survival
Chronic cytokine tone activates NF-κB and STAT3 transcriptional programmes that favour survival, invasion and sometimes immune evasion.
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.
Glutamine anaplerosis and nucleotide nitrogen demand are prominent in MYC-high and rapidly proliferating tumours. Dependence is heterogeneous.
Tumor Microenvironment
Osteoclast––plasma-cell triangle.
Metastasis Module
Leukemias and related neoplasms disseminate by trafficking rather than classical -driven carcinoma . Marrow, blood and lymphoid niches dominate.
Resistance Biology
Proteasome adaptation, efflux and marrow-niche protection.
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.
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.
Target / Mechanism
Tetracycline antibiotic that can inhibit matrix metalloproteinases and, at experimental exposures, protein synthesis. Oncology uses remain investigational.
Cancer relevance
MMP inhibition and experimental effects map to invasion and stem-like states in models.
Anti-invasive / mitochondrial experimental context. Convergence: Invasion, Cancer stemness, Mitochondrial oxidative phosphorylation.
Target / Mechanism
Lysosomotropic agent that raises endosomal/autophagosomal pH, impairing flux. Combination trials in oncology have been mixed; blockade is not equivalent to proven benefit.
Cancer relevance
Lysosomal pH elevation impairs flux. Early combination trials exist; benefit is not established and toxicity/retinal risk remain labelled concerns.
Autophagy-modulation research combinations. Convergence: Autophagy.
Disulfiram
Target / Mechanism
ALDH ; copper-complexed forms can inhibit proteasome and NF-κB-related survival programmes in models. Clinical oncology evidence remains limited.
Cancer relevance
ALDH and copper-dependent proteasome/NF-κB stress in models; clinical oncology remains limited.
ALDH / redox experimental context. Convergence: Cancer stemness, NF-κB, Oxidative stress.
