Summary
Chronic inflammation fuels tumor progression by recruiting myelomonocytic cells that promote cancer growth, immune evasion, and metastasis. Understanding these cancer-related inflammation mechanisms offers new diagnostic and therapeutic targets.
Area of Science:
- Oncology
- Immunology
- Cell Biology
Background:
- Tumors are consistently associated with a
- smouldering
- inflammation, regardless of the initial trigger.
- Myelomonocytic cells are recruited by tumors and mediate pro-tumoral functions through inflammatory mediators.
- Cancer-related inflammation involves key processes like malignant cell proliferation, immune evasion, angiogenesis, and metastasis.
Purpose of the Study:
- To discuss the cellular and molecular pathways driving cancer-related inflammation.
- To explore the role of myelomonocytic cells in orchestrating tumor-promoting inflammation.
- To highlight the potential of inflammation pathways as diagnostic, prognostic, and therapeutic targets in cancer.
Main Methods:
- Review of experimental and epidemiological evidence.
- Analysis of cellular and molecular mechanisms of cancer-related inflammation.
- Discussion of recent advances in the field.
Main Results:
- Evidence indicates a universal link between chronic inflammation and tumor progression.
- Myelomonocytic cells are critical mediators of cancer-related inflammation, supporting tumor growth and spread.
- The precise mechanistic basis of inflammation's role in cancer requires further elucidation.
Conclusions:
- Inflammation is intrinsically linked to cancer development and progression.
- Targeting cancer-related inflammation pathways presents significant therapeutic opportunities.
- Further research into these mechanisms is crucial for advancing cancer diagnostics and treatments.

01:31The Intrinsic Apoptotic Pathway
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
01:20The JAK-STAT Signaling Pathway
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
01:19Interactions Between Signaling Pathways
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

01:25Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
01:12Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
01:28Inflammatory Response
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
