Manipal :
Researchers from the School of Life Sciences (SOLS) and Kasturba Medical College, Manipal University , have identified cancer causing mutations in long standing ulcerative colitis subjects at risk of progressing into colorectal cancer. They have identified cancer causing mutations in new as well as previously identified oncogenes and tumor suppressor genes.
The mutations identified in the study can be used as marker for early diagnosis of ulcerative colitis associated colorectal cancer. The finding of the study is published in Nature Publishing Group journal British Journal of Cancer entitled “Targeted sequencing based analyses of candidate gene variants in ulcerative colitis-associated colorectal neoplasia”.
SOLS has been working in the field of cancer biomarker discovery, disease modelling and targeted drug delivery for the past several years, says its Director, Dr K. Satyamoorthy. He said: As there is an increased incidence of ulcerative colitis in India due to altered food habits, increased awareness, surveillance and availability of better diagnosis, it is important that early diagnosis of patients who are at risk of developing colorectal cancer is of paramount interest”.
Dr. Satyamoorthy who also led the investigations said the major challenge in the study was long-period of follow up required to monitor the patients with the ulcerative colitis and reluctance of the patients to undergo colonoscopy. Innovative discoveries such as this can lead to better management of individuals with the disease for early detection and personalized care”. While congratulating the researchers Dr. H. Vinod Bhat, Vice Chancellor, Manipal University said the University is supporting molecular genetics programme as there is plenty to discover to the benefit of patients. Manipal University is in unique environment that researchers, clinical practitioners and public health experts can work together to bring about change in the society on how the diseases are managed in individuals”.
Ulcerative colitis is a chronic inflammatory bowel condition with clinical symptoms of ulceration and bleeding of inner lining of colon. The age of onset for ulcerative colitis varies between 30 to 50 years. Ulcerative colitis subjects with more than seven years of pancolitis or more than 10 years of left sided colitis, experience a higher incidence of colorectal cancer than the rest of the population.
Dr. Sanjiban Chakrabarty, lead author of the manuscript said the DNA mutations discovered in the study could distinguish early dysplastic changes in high risk ulcerative colitis and has the potential to predict an adverse outcome.” Lead clinical investigator Dr. Ganesh Pai said the results of the studies are important in view of the rising incidence of both ulcerative colitis and colorectal cancer in the Asia Pacific in recent years. The results can help to better understand the development of colorectal cancer in ulcerative colitis, to develop tests for early diagnosis and to possibly select the best treatment strategies for subgroups of patients in the future”.
