Colorectal cancer (CRC) is a virulent tumor rising in the interior wall of the large bowel. CRC is the third deadliest cancer globally and is the 4th common in Iran. Fiestin is a flavone that is present in some fruits and vegetables and is suggested to have beneficial effects on human cancer cells. In the present study, we summarized the potential mechanisms of the effect of Fiestin on CRC. Electronic literature searches were conducted on Medline, Web of Science, and Google Scholar until March 2020. Our search was supplemented with the search of publisher databases like Elsevier and Springer. The search was conducted with “Fiestin” in combination with the following keywords: Colorectal Neoplasms, Colon, Rectum, Apoptosis, Inflammation, and “Precancerous Lesions” among humans, animal, and in-vitro studies. 14 articles during 2005 and 2018 assessed the effect of Fiestin on CRC. One was RCT, 3 of them were animal studies and 10 papers were performed on cell culture. Our Findings suggested that Fiestin may have positive effects on cancer cells due to its anti-inflammatory, apoptotic, anti-oxidative, and cell cycle modifying properties. According to the literature, it seems that Fiestin induces cell cycle arrest and suppresses cellular growth by modulating through some signaling pathways like inhibition of CDKs and Fiestin decreases protein levels of cell division cycles like CDC 2 and CDC25C. Fiestin may also induce cell apoptosis cascades such as activation of caspase 3, 7, and cleavage of procaspase 3 and inhibition of caspase 8. Fiestin also may have anti-inflammatory effects by inhibiting PGE2 production and expression of COX2. Additionally, it may have some anti-oxidant effects by reducing some tumor markers and enhancement levels of some anti-oxidants agents.

Diabetes mellitus and its comorbidities which result in dyslipidemia and cardiovascular diseases (CVD) are one of the leading causes of death in the world, and diet plays a major role in those disease incidences, especially through lipid oxidation mechanisms. This, in turn, leads to tissue inflammation and the formation of atheromatous plaques. Our objective was to evaluate the association between the inflammatory potential of the diet and the incidence of dyslipidemia or its subclasses. We included 599 T2DM patients (276 men and 323 women), aged 35 to 65 years from diabetes referral centers, including Gabric Diabetes Association, Iranian Diabetes Society, and other health centers in Tehran. The lipid profiles in serum were measured by the dietary inflammatory index (DII) was computed using a validated 148-item semi-quantitative food frequency questionnaire (FFQ). The DII score ranged between - 4.85 and 5.46 and its mean and standard deviation (SD) was (-0.02±1.65). Younger individuals had higher adherence to the inflammatory diet (p≤0.001). Moreover, in the higher quartiles of DII, lower levels of physical activities were seen (p=0.005). There were no significant differences in the distribution of BMI, waist circumference, or lipid profile across DII quartiles. In the overall analysis, no significant association was observed between DII and lipid profile in the crude model, but after adjusting for confounders (age, gender, BMI, physical activity, and energy intake), the DII score was found to be positively associated with total cholesterol (β=3.123, SE=1.478, p=0.035) in all participants. A pro-inflammatory diet, as measured by a higher DII score, was prospectively associated with a higher level of total cholesterol in serum. This result may shed a light on the prevention of incidence dyslipidemia and CVD in diabetic patients by intervention in dietary patterns.
