Summary
Cancer cells reprogram metabolism for energy and building blocks. The PGC-1/ERR axis influences this metabolic shift, impacting cancer cell proliferation.
Area of Science:
- Cellular metabolism
- Cancer biology
- Molecular endocrinology
Background:
- Proliferating cells require high energy and biosynthetic precursors.
- Cancer cells often switch to glycolytic metabolism and alter the tricarboxylic acid cycle.
- Estrogen-related receptors (ERRs) and PPARγ coactivator (PGC)-1 are key regulators of metabolic networks.
Purpose of the Study:
- To review the role of the PGC-1/ERR transcriptional axis in cancer cell metabolic reprogramming.
- To explore the integration of the PGC-1/ERR axis with oncogenes.
- To discuss the dual role of PGC-1/ERR modulation in cancer proliferation.
Main Methods:
- Literature review of studies on cancer metabolism and transcriptional regulation.
- Analysis of the PGC-1/ERR axis in the context of oncogenic pathways.
- Examination of experimental evidence for PGC-1/ERR modulation effects.
Main Results:
- The PGC-1/ERR axis is crucial for metabolic adaptation in cancer cells.
- This axis integrates with known oncogenes to support cancer growth.
- Modulating the PGC-1/ERR axis can exhibit both pro- and anti-proliferative effects.
Conclusions:
- The PGC-1/ERR transcriptional axis is a significant player in cancer metabolic reprogramming.
- Targeting this axis presents potential therapeutic strategies for cancer.
- Further research is needed to fully elucidate the complex roles of PGC-1/ERR in cancer.

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...

03:03mTOR Signaling and Cancer Progression
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.

02:38Mitogens and the Cell Cycle
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
01:22Amplifying Signals via Enzymatic Cascade
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze the...
01:33Cancer-Critical Genes I: Proto-oncogenes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
