Mechanism figures by research topic
Pick your field and load a detailed, field-specific prompt into the generator above. Edit any molecule or step before you generate, and check every relationship against your own data.
Autophagy
Nutrient stress: AMPK ↑ / mTORC1 ↓ → ULK1 complex → Beclin-1–VPS34 → LC3-II phagophore → autolysosome degradation.
Exosomes
Endosome → MVB with ESCRT-formed ILVs → Rab27-dependent fusion with the plasma membrane → exosome (CD63/CD9/CD81) uptake by recipient cells.
Gut microbiota
Fiber fermentation → SCFAs (acetate, propionate, butyrate) and secondary bile acids → GPR41/43, FXR/TGR5 signaling, barrier integrity and Treg induction; dysbiosis → LPS leak → inflammation.
DNA methylation & epigenetics
DNMT3A/3B (de novo) and DNMT1 (maintenance) methylate promoter CpG islands → MBD proteins recruit HDACs → gene silencing; TET enzymes oxidize 5mC for demethylation.
Stem cells
OCT4/SOX2/NANOG core network maintains pluripotency and self-renewal; differentiation to three germ layers; OSKM reprogramming of somatic cells to iPSCs.
Hypoxia & HIF-1α
Normoxia: PHD hydroxylation → VHL ubiquitination → proteasomal degradation of HIF-1α; hypoxia: HIF-1α/HIF-1β bind HREs → VEGFA, GLUT1, LDHA, EPO.
ER stress & UPR
Unfolded proteins sequester BiP/GRP78 → PERK–eIF2α–ATF4–CHOP, IRE1α–XBP1s and ATF6 arms → adaptation or apoptosis.
Mitochondrial dysfunction
ETC damage → ROS overproduction and loss of ΔΨm → BAX/BAK MOMP → cytochrome c release → caspase-9/3 apoptosis; PINK1/Parkin mitophagy clears damaged mitochondria.
Macrophage polarization
LPS + IFN-γ → STAT1/NF-κB → M1 (iNOS, TNF-α, IL-1β, IL-12); IL-4/IL-13 → STAT6 → M2 (Arg1, CD206, IL-10, TGF-β).
T cell exhaustion
Chronic antigen → sustained TCR/NFAT signaling and TOX → PD-1, TIM-3, LAG-3, TIGIT up → loss of IL-2, TNF-α, IFN-γ; TCF1+ progenitors respond to anti-PD-1.
Single-cell RNA-seq workflow
Tissue dissociation → droplet capture with cell barcodes and UMIs → sequencing → QC, normalization, PCA, clustering and UMAP → annotation, DEGs, trajectory and cell–cell communication.
What can this AI mechanism figure generator do?
This free AI mechanism figure generator turns a plain-text description of a molecular, biological, or physical mechanism into a clear, publication-ready figure. It captures the components, their interactions, and the sequence of events — from enzyme catalysis and signaling cascades to drug mechanisms of action and catalytic cycles — ready for journals such as Nature, Cell, Science, and PNAS.
Why researchers need mechanism figures
- Explain how a process works step by step, beyond what text alone can convey
- Show activation, inhibition, and regulatory relationships at a glance
- Help reviewers and readers grasp complex pathways quickly
- Communicate a novel mechanism or proposed model clearly
- Strengthen the impact of submissions to high-profile journals
How to create a clear mechanism figure
An effective mechanism figure follows the natural flow of the process: introduce the key players, show how they interact, and lead the reader through each step with consistent arrows and labels. Use standard notation for activation and inhibition, keep text minimal, and group related events spatially. SciDraw AI drafts mechanism figures that follow these conventions automatically, giving you a publication-ready starting point to refine.
Common elements in mechanism figures
- Labeled molecular or cellular components (proteins, receptors, enzymes)
- Directional arrows showing the sequence of events
- Activation arrows and inhibition bars for regulatory relationships
- Modification markers such as phosphorylation or binding indicators
- Cellular compartments or membranes that frame the process
- A clear start point and end point or outcome
Frequently Asked Questions
What types of mechanism figures can I create?
You can create signaling pathway diagrams, drug mechanism of action figures, enzymatic reaction illustrations, protein-protein interaction maps, gene regulatory networks, cellular process schematics, immune response cascades, and metabolic pathway visualizations.
Does SciDraw AI understand biomedical pathway terminology?
Yes. SciDraw AI recognizes biological terms — proteins (p53, EGFR, mTOR), pathways (NF-kB, MAPK, PI3K/Akt), processes (apoptosis, autophagy, angiogenesis), and molecular interactions (phosphorylation, ubiquitination, acetylation). Simply describe the mechanism in natural language, then review the generated relationships.
Can I show activation and inhibition relationships?
Absolutely. The generator supports standard pathway notation including activation arrows, inhibition bars, phosphorylation indicators, complex formation, translocation, and transcriptional activation/repression markers.
Are the figures suitable for high-impact journal submission?
Yes. All exports meet the figure requirements of journals like Nature, Cell, Science, PNAS, and specialty journals. High-resolution (300+ DPI) output with scalable vector formats ensures your mechanism figures look professional at any size.
Can I illustrate a drug mechanism of action?
Yes. Describe your drug target, binding mechanism, downstream effects, and therapeutic outcome. SciDraw AI will generate a professional MOA figure draft showing the pharmacological pathway from drug-target interaction to clinical effect.
How do I create a figure for a novel mechanism I discovered?
Describe the components involved, their interactions, and the sequence of events. SciDraw AI does not rely on a fixed pathway database — it drafts custom mechanism figures from your natural language description, making it useful for illustrating novel findings that still require expert review.
Can I edit the figure or export it as SVG or PowerPoint?
Yes. Download the result as a high-resolution PNG, or click Open in editor to keep refining it. From the editor you can convert it to an SVG vector file (10–15 credits), a PowerPoint PPTX file (10 credits) or a Visio file (20 credits).
How accurate are the generated figures?
The AI draws and labels what you describe, but it does not check the science for you. Review every label, arrow and value before you use the figure, then fix anything that is off by refining your description and regenerating, or by adjusting it in the editor.
