In the history of mankind, cancer has always been regarded as the ultimate enemy that is difficult to defeat. Whether it is excision, radiotherapy or chemotherapy, these traditional methods only temporarily control the reproduction of cancer cells, but cannot prevent them from existing. However, the latest scientific research brings exciting news: permanently dormant tumors may be an entirely new strategy that injects new hope into humanity's fight against cancer.
As we immerse ourselves in this amazing field of science, we cannot help but marvel at the infinite boundaries of human intelligence. While there are still many unknowns before the permanent dormancy of cancer is truly achieved, a promising future is emerging. It is believed that in the near future, the era of "cancer cells cannot be killed" will be a thing of the past, and mankind will usher in a new era of anti-cancer.
The principle of the permanent dormancy method of tumors: passive blockade of nutrition**
Tumor cells need a lot of nutrients such as glucose, amino acids, and fatty acids to survive and grow. Normally, these nutrients are supplied through the bloodstream to provide cells with energy and substances necessary for survival. However, scientists have found that specific methods can interfere with the process by which tumor cells acquire nutrients, leaving them dormant.
A common way to passively block nutrients** is by modulating the environment around tumor cells. Researchers have found that tumor cells rely on blood** for nutrients. As a result, they try to alter the structure and function of the blood vessels surrounding the tumor to reduce nutrient supply. This can be achieved through the use of drugs or by interfering with the angiogenesis process. For example, some drugs can inhibit the signaling pathways of angiogenesis, causing blood vessel growth to stop or slow down. As a result, the tumor cells are unable to get enough nutrients from the blood and eventually go dormant.
Another way to passively block nutrients** is to do this by altering the properties of the tumor cells themselves. Researchers have found that some specific genes and signaling pathways play an important role in the survival and growth of tumor cells. Therefore, they try to alter the activity of these signaling pathways through gene editing techniques or chemopharmaceutical interventions, thereby interfering with the metabolism and nutrient uptake of tumor cells. For example, some drugs can inhibit the ability of tumor cells to uptake and utilize glucose, preventing them from getting enough energy to grow.
The method of passively blocking nutrients** has certain advantages and potential. First, this approach does not directly attack tumor cells, but rather achieves control of the tumor by altering their surroundings or gene expression. This means that the method may be less resistant and secondly, the method of passive blockade of nutrition can be combined with other methods, such as chemotherapy or radiotherapy, to achieve better results.
The principle of the permanent dormancy method of the tumor: activates the immune system
In the human body, there is a rather complex immune system, which is able to recognize and destroy invading pathogens and maintain the body's health. However, when tumour cells are produced, the immune system is usually unable to remove them completely, resulting in rapid growth of the tumor. Therefore, activating the immune system becomes an important means to fight tumors.
Specifically, there are many ways to activate the immune system, and one of the most common methods is to employ immune checkpoint activation. Immune checkpoint activation can prevent tumor cells from evading the immune system's attack by interacting with immune cells, thereby enhancing the killing power of immune cells against tumor cells. This method is of great interest to scientists because it activates the immune system without causing damage to normal cells.
There is also a method called CAR-T cells** that is also widely used in tumors**. CAR-T cells** are T cells extracted from the patient's body, modified by genetic recombination technology, and then injected back into the patient's body. Engineered T cells have a stronger ability to kill tumor cells and can effectively recognize and attack tumor cells. With this method, the patient's immune system is effectively activated, which inhibits the growth and spread of the tumor.
In addition to the above two methods, scientists are constantly exploring other ways to activate the immune system. For example, vaccination can induce the immune system to produce a specific anti-tumor immune response, or gene editing technology can be used to improve the function of the immune system. These methods are designed to further improve the immune system's ability to effectively recognize and attack tumors, so as to achieve the goal of permanent dormancy of tumors.
The principle of the permanent dormancy approach to tumors: targeting genes key to cell survival
The growth and development of tumor cells are regulated by many genes, some of which are key genes that make tumor cells have characteristics that are not controlled by normal cells. The approach of targeting genes that are key to cell survival is to focus on these specific genes and interfere with the normal function of tumor cells by precisely targeting their relevant signaling pathways, prompting them to enter a dormant state.
In specific experiments, scientists first analyzed the gene expression profiles of tumor tissues and non-tumor tissues through high-throughput sequencing technology to screen out genes that are key to the survival of tumor cells. Next, gene editing technology, such as CRISPR Cas9, was used to change these genes in a targeted manner to observe the changes in tumor cells after the changes. Through this process, scientists were able to identify specific genetic alterations that trigger the dormancy effect of tumor cells.
Approaches to target genes key to cell survival have many advantages. First of all, this method is highly precise and only acts on specific genes and does not cause damage to other normal cells. Secondly, it can directly target the survival mechanism of tumor cells, avoiding the extensive damage to normal cells in the traditional way. In addition, approaches that target genes key to cell survival can also be targeted at individualized tumors**, as each person's tumor genome is different, so it is important to target genes in different populations.
The principle of the permanent dormancy method of tumors: inhibition of tumor angiogenesis
With the continuous development of medical technology, people's understanding of tumors is becoming more and more deep. A tumour is a malignant mass formed by the proliferation of abnormal cells in the body, and its growth is mainly dependent on blood vessels**. Therefore, inhibition of tumor angiogenesis has become an important tumor method.
Tumor angiogenesis, also known as angiogenesis, is one of the key links in tumor growth and metastasis. Normally, human cells control the growth of blood vessels through a series of signaling pathways to maintain the normal blood supply to tissues. However, tumor cells can alter these signaling pathways, promote blood vessel growth, and provide themselves with adequate nutrients and oxygen to meet their need for rapid proliferation.
There are many ways to inhibit tumor angiogenesis, one of the most common and effective is the use of anti-angiogenic drugs. These drugs inhibit tumor growth by interfering with the interaction between tumor cells and vascular endothelial cells, blocking signaling pathways required for angiogenesis. One of the most well-known anti-angiogenic drugs is the "vascular endothelial growth factor receptor (VEGFR)".
The principle of the permanent dormancy method of tumors: the research progress of stem cell ** tumors
Stem cells have the ability to self-renew and differentiate into multiple cell types, so they are considered to have great potential in tumors. The basic principle of stem cells** is to transplant stem cells cultured in vitro into the patient's body to inhibit or kill tumor cells and promote the repair and regeneration of normal cells through their special functions and expressed bioactive factors.
At present, the research of stem cell ** tumor has made some progress. Scientists have successfully solved the problem of stem cells through continuous improvement of in vitro culture and expansion technology of stem cells. At present, the commonly used stem cells** mainly include embryonic stem cells, adult stem cells and induced pluripotent stem cells. The abundance of these stem cells** makes stem cells** more viable.
The researchers have made some preliminary experimental results in stem cell ** tumors. One study found that the growth and spread of breast cancer cells could be significantly slowed by converting induced pluripotent stem cells into neoplastic stem cells. In addition, stem cells can selectively migrate into tumor tissues, release various anti-tumor factors, and inhibit tumor angiogenesis, thus playing an anti-tumor role.
While cancer cells have long been a problem in medicine, new research offers a silver lining: to leave tumors dormant permanently. This innovative approach has created optimism about the future of cancer.
By leaving the tumor cells dormant, scientists have found that they no longer have the ability to spread, reducing the risk of cancer spreading. This approach not only reduces patient suffering, but also improves the success and survival rates.
There are still many unknowns that need to be addressed regarding the safety and usefulness of this new technology. Scientists need to dig deeper to ensure that tumor cells do not reactivate during dormancy. In addition, the effects on long-dormant tumor cells and the possible causes of tumor cells in patients also need to be observed and analyzed in more detail.
Still, the concept of permanent dormancy in tumors gives hope. If this approach is finally applied to clinical practice and is successful, it will undoubtedly be a historic breakthrough for cancer patients. We also look forward to the results of more relevant research in the future, which will bring more positive changes and breakthroughs in this field. Let's look forward to injecting new strength into the fight against cancer.
