Aberrant crypt foci (ACF) is the precursor lesion of colorectal carcinogenesis (CRC), one of the most common malignancies in the world. Many studies have reported that people with higher phytochemical intake are at a reduced risk of developing ACF. One example of the botanical potential of preventive plant products is Cnidoscolus aconitifolius (CA), commonly known as Chaya. This study evaluated the phenolic profile of CA and the effects of the daily consumption of CA leaf infusion on the formation of ACF, histopathological lesions, and molecular biomarkers after azoxymethane (AOM) and dextran sulfate sodium (DSS) induced premalignant colon lesions in rats treated with for 16 and 32 weeks. The phenolic composition of the CA infusion was identified by reversed phase-high performance liquid chromatography-diode array detection (RP-HPCC-DAD). After sacrifice, a 4 cm segment was collected from the distal part of the colon and stained with methylene blue to look for ACF. Furthermore, 4 μm of colon, liver, and kidney was collected and stained with hematoxylin and eosin for histopathological analysis, along with 7 μm of colon for immunohistochemistry analysis. Eleven phenolic compounds were identified in the infusions, and ACF formation was reduced by 29.5% at the subchronic and by 64.6% at chronic stages. Lesions on kidney, liver, and colon tissue were also reduced. Our data suggest that CA treatment has preventive effects against AOM-/DSS-induced premalignant colon lesions in colon rats at the promotion level, inhibiting the cell proliferation of early neoplastic lesions and colonic inflammation through the decrease of β-catenin by 41.8% at the subchronic stage and 29% at the chronic stage, along with a 46.2% reduction of cyclooxygenase 2 (COX-2) at long term, despite a high expression of NF-κB (30.3% at the subchronic stage and 22.8% at the chronic stage).

Antidiabetic and Renal Protective Properties of Berrycactus Fruit (Myrtillocactus geometrizans)

Native plants are exceedingly valuable because they are sources of natural products with applications for the treatment of various diseases. Berrycactus fruit (Myrtillocactus geometrizans) has been consumed in Mexico since ancient times due to its sweetness. The hypoglycemic and antioxidant effects of this fruit were evaluated in streptozotocin-induced diabetic rats by replacing the drinking water with berrycactus juice (2 or 4 g/kg). After 4 weeks of treatment, the diabetic animals showed an improvement in their conditions, as reflected by diminished circulating glucose levels (up to 50%), diminished triglycerides (up to 67%), and diminished total cholesterol (up to 35%) compared with diabetic nontreated controls, and these effects were dose dependent. The dose of 4 g/kg produced the best results. The administration of the juice improved renal function and helped to restore normal levels of glutathione and glutathione S-transferase in the kidney. The expressions of two transcription factors that are relevant to normal functioning of the kidney changed due to the administration of the juice; compared to the diabetic nontreated controls, the level of nuclear factor kappa of B-cells diminished, and the total level of peroxisome proliferator-activated receptor gamma increased. The results of this study highlight the importance of the compounds that are present in berrycactus fruit as adjuvants in the treatment of diabetes and its renal complications.
