Abstract

Colorectal cancer (CRC) is the third most prevalent neoplasm worldwide and fourth most frequent reason of cancer-related death throughout the world. About 70% of malignant tumors are related to lifestyle and environmental factors, and better knowledge of their significance might reduce the prevalence of CRC. The cyclooxygenase-2 (COX-2) inhibitory and other direct and indirect pathways of aspirin are translated to inhibition proliferation and enhanced apoptosis of cancer cells. Many studies showed the benefits of aspirin in reducing the risk of CRC development, cancer-related mortality and adenoma prevalence rate in general population, but not in high risk populations. The role of sulindac in CRC prevention is uncertain and the use of this drug is rather uncommon. Celecoxib - COX-2 selective inhibitor- showed efficacy in decreasing of colon adenoma recurrence only in some studies. The protective role of microelements is controversial. The beneficial effects of supplementation of selenium, calcium, folic acid, methionine, antioxidant supplements and probiotics are still not certain. A high energy diet consisting of red meat, animal fat, highly processed foods and unsaturated fats increases the risk of CRC. Carcinogenic role of f...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.
