New Link between Cancer and Alcohol. Alcohol Triggers Cell Transformations Which May Lead to Tumor Cells Spreading
Even though past investigations associated the consumption of beverages containing alcohol to cancer and its metastasis, the process behind this relationship was never completely understood. However, a team of scientists from the Rush University Medical Center underwent a study regarding this matter and discovered a cell pathway which may provide explanations about the above mentioned association.
The investigation was released in the Alcoholism: Clinical and Experimental Research edition. The study comprises the researchers` findings regarding how alcohol triggers the epithelial-to-mesenchymal transition. During this transition, the mild cancerous cells transform in aggressive one and start invading the whole body in a process entitled metastasis.
As assistant professor Christopher Forsyth from the medicine and biochemistry division within the Rush University Medical Center explains the information provided by the team of investigators led by him is the first of its kind. This is due to the fact that their data presents the pathway in which alcohol stimulates specific triggers within a cell which are implicated in the metamorphosis into an aggressive form of the cells.
The notion of epithelial-to-mesenchymal transition is a highly researched matter nowadays due to the fact that it represents one of the processes involved in the mechanism of cancer spreading in the whole organism. An amalgam of laboratory investigations and clinical trials shows that this epithelial-to-mesenchymal transition is a prime factor in triggering the aggressiveness of the cancerous cells.
Professor Christopher Forsyth stated that the malign cells acquire a dangerous characteristic in the moment when they start spreading in the whole body. The operations can resection a malign tumor, but the aggressive cells have the ability to spread out in the whole human organism and conquer it. If medical doctors could stop this process, they would be able to limit the spreading of the malignant tumors.
The team of investigators put alcohol in cellular lines coming from colon and breast cancers and observed them in order to find the biochemical distinct signs of the epithelial-to-mesenchymal transition also including the presence of both Snail which is a transcription agent and the receptor concerned with the growth agent of the epidermis. The Snail represents the epithelial-to-mesenchymal transition`s control factor. On experiments undergone on mice, it was observed that if there is an over-expression of this factor, multi tumors are prone to develop. The second agent, the epidermal growth one is just like a drug for the cancer cells, they require large quantities of it.
The testing undergone in laboratories proves that alcohol triggered both factors and also other biochemicals agents related to the epithelial-to-mesenchymal transition. The trials also proved that the cells which were put in alcohol lost their strong links to adjacent cells, a characteristic which resembles the metastasizing process of the malign tumors.
Furthermore, professor Christopher Forsyth`s team of researchers discovered that the similar group of biomarkers was triggered in healthy intestinal cells which were put in alcohol. In addition to the aggressive metamorphosis alcohol triggers in cancer cells, this finding could mean that alcohol may also trigger the development of cancer.
