Pay attention to the diet structure to prevent cancer from “finding you”

   “Illness comes from the mouth”, eating incorrectly, or even eating too much, may “eat something wrong”. The reporter learned from the Sixth Affiliated Hospital of Sun Yat-sen University that the research of Professor Li Menghong’s research group found that the key gene ILF3 in the process of tumor carcinogenesis can promote malignant proliferation by promoting tumor cells to take up a large amount of surrounding nutrients. Therefore, excessive intake of nutrients, especially foods rich in serine and methionine, will be more likely to induce cancer. The research results are expected to bring new ideas for the treatment of bowel cancer.

   On November 26, the research group of Professor Li Menghong from the Sixth Affiliated Hospital of Sun Yat-sen University published an article in Cell Research. The study found that the serine synthesis pathway can be over-activated by ILF3 to provide cells with energy supply and nucleotide synthesis raw materials As well as reducing power, inhibit oxidative stress and promote the malignant growth of tumor cells.

  ILF3 gene is a key gene in the process of tumor carcinogenesis. This study revealed for the first time the key role and regulatory mechanism of the mRNA binding protein ILF3 in maintaining the metabolism of serine in colorectal cancer cells and promoting the malignant progression of colorectal cancer. At the same time, in vivo and in vitro experiments have shown that ILF3 can be used as a new colorectal cancer. The prognostic prediction markers and potential therapeutic targets, its inhibitors have potential drug development value, and have applied for Chinese patents. Through upstream analysis, Li Menghong’s research team suggested that this gene may be a factor leading to resistance to cetuximab, the first-line drug for colorectal cancer. Targeting this gene and downstream metabolic pathways may provide new ideas for solving cetuximab resistance in the future.

   Colorectal cancer is the third most common malignant tumor in the world. In recent years, the incidence of colorectal cancer has increased year by year in my country. Li Menghong introduced that the pathogenesis of colorectal cancer is complicated and the course of the disease is long. It requires multi-step holistic observation. Cetuximab has a good effect and reactivity against certain subtypes of colon cancer. However, there are still some people who are not effective to cetuximab. This study started from the clinic and identified the key gene ILF3 in the process of tumor carcinogenesis through sequencing and other large omics methods. The key gene, ILF3, can “add bricks and tiles” to tumor cells and promote the malignant proliferation of tumor cells by promoting more greedy intake of surrounding nutrients by tumor cells, especially glucose and serine.

  Excessive intake of nutrients, especially foods rich in serine and methionine, has been reported to promote the occurrence and development of cancer. Nowadays, people’s diet is becoming more and more high-fat and high-protein, and it is more likely to induce cancer. Li Menghong suggested that eating more fruits and vegetables and less meat can effectively prevent the occurrence of tumors.
