Summary
Altered caveolae (small cell membrane invaginations) promote tumor metabolic heterogeneity and a catabolic tumor microenvironment, worsening patient survival.
Area of Science:
- Cell biology
- Cancer research
- Metabolic signaling
Background:
- Caveolae, a subset of lipid rafts, are known signaling organelles.
- Emerging evidence links caveolae to tumor metabolic heterogeneity.
Purpose of the Study:
- To review the role of caveolae in tumor progression.
- To emphasize the metabolic and cell signaling effects of caveolae.
- To discuss how caveolae transform the tumor microenvironment.
Main Methods:
- Literature review of studies on caveolae, lipid rafts, and cancer metabolism.
- Analysis of signaling pathways and metabolic reprogramming in cancer cells.
- Examination of the tumor microenvironment's role in cancer progression.
Main Results:
- Caveolae alterations contribute to a catabolic tumor microenvironment.
- This environment supports oxidative mitochondrial metabolism in cancer cells.
- Altered caveolae are associated with poor patient survival rates.
Conclusions:
- Caveolae play a critical role in tumor progression through metabolic and signaling alterations.
- Targeting caveolae may offer new therapeutic strategies for cancer.
- Understanding caveolae's impact on the tumor microenvironment is crucial for improving cancer treatment.

Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Autocrine signaling is one of the many signaling mechanisms that function inside multicellular organisms to carry out intercellular communication. In this type of signaling mechanism, the same cell that secretes an extracellular signaling molecule also expresses the receptors to bind and respond to that signaling molecule.

5.1K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
