Live Biotherapeutics Drug Discovery Services for Colorectal Cancer (CRC)
Evidence has shown that taking probiotics is a protective approach for proper maintaining of healthy gut microbiota and also reducing the risk of colorectal cancer (CRC). Equipped with world-leading technology platforms and industry-leading expertise in the development of next-generation probiotics (NGPs), Creative Biolabs has accumulated substantial experience in the NGPs identification for single strains and blends to help our clients in the development of probiotics for the treatment of CRC. Our comprehensive portfolio of microbial and stability testing analysis fully supports all the processes of good manufacturing practice (GMP).
Introduction of CRC
CRC is the third most commonly diagnosed cancer with more than 1 million new cases annually and is responsible for the death of more than 500,000 people. CRC develops by the accumulation of mutations, starting in stem cells at the base of the crypts, and usually begins as a non-cancerous polyp. CRC incidence can be associated with several genetic factors such as germline mutations in the mismatch repair genes and adenomatous polyposis coli (APC) gene. In addition to genetic predispositions, environmental factors such as lifestyle and diet play an important role in CRC risk. This lifestyle and diet lead to disturbances in the intestinal environment, including the luminal content and microbiota. The microbiota plays a role in generating biochemical and physiological conditions that may increase the number of colonic pre-neoplastic lesions. Modulation of the unbalanced gut microbiota can reduce the risk of colon cancer risk.

CRC and Probiotics
Studies showed the effect of probiotics on manipulating the composition of gut microbiota, thus positively affect the host by improving intestinal barrier integrity, inhibiting the growth of pathogens, reducing the metabolism of pro-carcinogenic substances. Based on their anticancer properties, probiotics can be used in combination with conventional CRC therapies, such as surgery and chemotherapy. Data obtained suggest probiotics are effective in preventing and inhibiting the growth of intestinal cancer. The administration of probiotics along with CRC treatment may alleviate the secondary effects related to chemotherapy. Moreover, the prevention of cancer therapy-induced mucositis by probiotics has been investigated in randomized clinical trials with some promising results. Furthermore, clinical reports show that probiotics can improve the integrity of the gut mucosal barrier and decrease infectious complications in surgical CRC patients.
