London, Dec 10: Frequent travelling that causes jet lag could increase risk of cancer as it tends to disrupt our body clocks that are controlled by the same mechanism that causes tumors, reveals study.
The findings, reported in the Daily Mail, discovered that internal human body clocks have a major influence on cell multiplication and has the potential to prevent cancer.
“Our internal clock is in sync with external light and dark cues, and prompts people’s behaviour and activity levels,” lead author Angela Relogio from the Charite-Medical University in Berlin, was quoted as saying by Daily Mail.
“Based on our results, it seems to us that the clock is likely to act as a tumor suppressor,” Relogio added.
For the study, published in the journal PLOS Biology, researchers examined a protein known as RAS, which is inappropriately activated in around a quarter of cancerous cells, in mice.
This takes place via two proteins — INK4 and ARF — that are known to conquer cancer.
“One cannot stop wondering whether disrupted circadian timing should be included as a next potential hallmark of cancer,” Relogio asserted.
Changes in the biological clock have also been known to up the risk of heart related diseases and diabetes.
