Targeting Zinc(II) Signalling to Prevent Cancer
Metal Ions in Life Sciences
|February 3, 2018
Summary
Zinc acts as a signaling molecule, influencing cell pathways crucial for cancer growth. Its role in inhibiting phosphatases highlights its potential as a novel target for cancer therapy.
Area of Science:
- Biochemistry
- Molecular Biology
- Cancer Research
Background:
- Zinc is increasingly recognized for its role in cellular signaling.
- Zinc acts as a second messenger, rapidly activating signaling pathways upon extracellular stimulus.
- Release of intracellular zinc(II) stores modulates key cellular processes.
Purpose of the Study:
- To explore the role of zinc signaling in cancer.
- To investigate zinc as a potential therapeutic target for cancer treatment.
- To understand how zinc influences cancer-driving signaling pathways.
Main Methods:
- Review of current literature on zinc signaling and cancer.
- Analysis of zinc's effect on tyrosine phosphatases and kinases.
- Examination of zinc-mediated signaling pathway activation.
Main Results:
- Zinc release inhibits tyrosine phosphatases, preventing tyrosine kinase inactivation.
- This inhibition promotes the activation of tyrosine kinase-dependent signaling pathways.
- These pathways are frequently implicated as drivers of aberrant cancer growth.
Conclusions:
- Zinc signaling plays a significant role in promoting aggressive cancer growth.
- Targeting zinc and its signaling pathways presents a promising strategy for cancer therapy.
- Further research into zinc's mechanisms could lead to new anti-cancer treatments.

02:59Cancer Prevention
8.2K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

02:57Targeted Cancer Therapies
9.0K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

03:03mTOR Signaling and Cancer Progression
4.9K
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.

02:03What is Cell Signaling?
131.1K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate to respond to the environment.

01:45Endocrine Signaling
68.3K
Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.

01:21Paracrine Signaling
59.7K
Paracrine signaling allows cells to communicate with their immediate neighbors via secretion of signaling molecules. Such a signal can only trigger a response in nearby target cells because the signal molecules degrade quickly or are inactivated if not taken up. Prominent examples of paracrine signaling include nitric oxide signaling in blood vessels, synaptic signaling of neurons, the blood clotting system, tissue repair/wound healing, and local allergic skin reactions. Nitric oxide as a...
