Acute lymphoblastic leukemia
Subtype of Leukemias
Clinical / Scientific
ALL is a B- or T-lymphoid blast neoplasm with age-specific genetics (ETV6-RUNX1, hyperdiploidy, BCR-ABL1, Ph-like lesions, T-ALL NOTCH). Apoptotic competence and CNS sanctuary biology matter. Experimental metabolic adjuncts are not substitutes for paediatric/adult hematologic protocols.
Core Biological Drivers
Lineage transcription fusions
ETV6-RUNX1 and others.
Kinase lesions
BCR-ABL1 and Ph-like ALL.
NOTCH in T-ALL
Developmental pathway.
Key Pathways
Scientific explanation
receptors signal through JAKs to STATs. in particular supports survival, invasion and inflammatory gene programmes in many solid and hematologic tumours.
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
Notch receptors undergo ligand-induced cleavage to NICD, altering lineage and stem/progenitor decisions. Context determines oncogenic versus tumour-suppressive roles.
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
Intrinsic and extrinsic apoptotic programmes remove damaged cells. Evasion of is a hallmark, via BCL-2 family imbalance, death- decoys, or p53 loss.
Scientific explanation
MYC factors coordinate biomass accumulation, ribosome biogenesis, and glutamine use. Amplification or pathway activation is common.
Scientific explanation
Aerobic (Warburg metabolism) supports ATP, biomass and redox buffering even when oxygen is available. Hexokinase, PKM2 and lactate export are frequent nodes.
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.
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
CNS and testis sanctuaries, marrow .
Metastasis Module
Leukemias and related neoplasms disseminate by trafficking rather than classical -driven carcinoma . Marrow, blood and lymphoid niches dominate.
Resistance Biology
-domain mutations in Ph/Ph-like disease and apoptotic escape.
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.
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.
