Compare mitochondrial and death-receptor signaling in one labeled figure, with an optional BID connection between the branches.

An apoptosis diagram shows the intrinsic and extrinsic pathways that converge on executioner caspases. Compare mitochondrial and death-receptor signaling in one labeled figure, with an optional BID connection between the branches. Switch between intrinsic and extrinsic branches or show their connection through BID; the selected branches and scientific labels stay with the exported figure.

Apoptosis Diagram Features

SciFig’s apoptosis diagram brings the inputs, diagram choices and exported result into one focused tool.

Compare intrinsic and extrinsic pathways

Place the mitochondrial pathway beside the death-receptor pathway. Caspase-9 and caspase-8 remain on their own branches before the shared execution stage, so the diagram communicates convergence without making the initiating signals appear identical. Both routes remain connected to caspase-3/7.

  • Show the intrinsic branch
  • Show the extrinsic branch
  • Retain a shared execution stage
Compare intrinsic and extrinsic pathways

Focus on mitochondrial signaling

Use the intrinsic view to connect mitochondrial signaling with caspase-9 and downstream executioner caspases. Removing the other branch gives an introductory explanation room for the mitochondrial components, while keeping the same overall pathway vocabulary. Cytochrome c and the apoptosome provide the intermediate molecular context.

  • Focus on mitochondrial signaling
  • Identify caspase-9
  • Retain executioner caspases
Focus on mitochondrial signaling

Show receptor signaling and BID crosstalk

Display the extrinsic branch with its death-receptor context and caspase-8. Turn on the optional BID connection when the explanation includes communication with the mitochondrial pathway. The connection is a distinct cross-pathway edge rather than another initiation branch.

  • Identify death-receptor signaling
  • Keep caspase-8 on its branch
  • Toggle the BID connection

Annotate a pathway for your audience

Use SciFig’s apoptosis diagram to change the node labels and title to match the explanation beside the figure. Export SVG for a vector diagram or PNG for lecture material. The pathway layout keeps the two initiating routes and their common endpoint together as the labels change.

How to Create the Figure

Use the apoptosis diagram controls below to prepare the figure from your selected mechanism and labels.

  1. Choose intrinsic, extrinsic or both

    Start with both initiating branches for an overview of apoptosis, or choose the intrinsic or extrinsic branch for a focused explanation. The preview retains the shared execution stage so the selected route stays connected to its downstream mechanism.

  2. Choose whether to show BID

    Turn on BID crosstalk when your explanation includes the connection from extrinsic signaling to the mitochondrial branch. The two initiating routes remain visible with that connection. Use the branch controls to return to a simpler pathway comparison.

  3. Edit the title and labels

    Enter a descriptive title and replace the node or structure labels with the terminology used in your document. The preset retains its arrangement while the visible names change. Keep molecular abbreviations consistent with the explanation beside the figure.

  4. Download the labeled figure

    Choose SVG for a scalable vector figure or PNG for a slide, handout or document. The exported diagram retains the selected view and labels. Keep the figure alongside the corresponding explanation so later wording changes can be reflected in another export.

Apoptosis Diagram Uses

Use a labeled apoptosis diagram to connect the explanation in your material with a visible figure.

Intrinsic and extrinsic apoptosis pathways with caspase-9 and caspase-8 converging on caspase-3/7

Explain programmed cell death

Prepare an introductory teaching figure that separates apoptosis from other cell-death processes. Show the two initiation routes and their shared execution stage, then use the labels to connect the illustration to the terminology in the lesson.

Introduce the mitochondrial branch

A seminar introduction can focus on the intrinsic route before adding receptor signaling. Export the mitochondrial view with caspase-9 and executioner caspases visible. This gives the audience a clear route through the mechanism rather than a list of disconnected proteins.

Discuss a death-receptor experiment

Place a labeled extrinsic pathway beside the description of a death-receptor experiment. Caspase-8 and the downstream execution stage provide a mechanism overview. The figure organizes the explanation; measured assay results can remain in a separate data chart.

Teach pathway crosstalk

Use the optional BID connection when a discussion moves beyond two isolated branches. Showing that edge explicitly helps the reader follow how an extrinsic signal can connect with mitochondrial signaling while retaining the initiating route on each side.

Prepare a mechanism panel

Export SVG for a pathway panel that will sit beside experimental images or charts. Keep the molecular labels consistent with the manuscript’s terminology. The clean mechanism overview can introduce the proposed pathway without turning the drawing into a quantitative assay result.

Build a labeled study reference

Create a figure with the two branches and common execution stage for revision material. Change the labels to the vocabulary used in the course and export PNG for the handout. A signaling-pathway figure can extend the discussion to other regulatory connections.

How Researchers Use SciFig

My lecture moved from mitochondrial signaling to death-receptor signaling, and the original slide mixed the initiator labels. The apoptosis diagram let me keep caspase-9 and caspase-8 on their own branches. I exported the combined view so students could follow both routes into the common execution stage in their notes.
