Consumption of Brassica vegetables provides beneficial effects due to organic isothiocyanates (ITCs), a resultant product of the enzymatic hydrolysis of glucosinolate secondary metabolites. The ITC L-sulforaphane (L-SFN) is the principle agent in broccoli that demonstrates several modes of anticancer action. While the anticancer properties of ITCs like L-SFN have been extensively studied and L-SFN has been the subject of multiple human clinical trials, the scope of this work has largely been limited to those derivatives found in nature...

High doses of β-phenylethyl isothiocyanate (PEITC), a phytochemical in cruciferous vegetables, are not feasible for consumption due to a strong mouth-tingling effect. This study investigated the anti-cancer effect of PEITC at sensory acceptable doses. In vitro, PEITC was selectively toxic to oral cancer cells (CAL-27, FaDu, SCC4, SCC 9, SCC15, SCC25 and TU138), compared to oral keratinocytes (OKF6/TERT2 and NOK/Si). In vivo, 5 and 10 mg kg-1 PEITC, equivalent to human organoleptically acceptable doses, retarded tumor growth and prolonged the survival of mice bearing p53-mutated oral cancer cells - TU138 xenograft...

Resveratrol, a dietary product present in grapes, vegetables and berries, regulates several signaling pathways that control cell division, cell growth, apoptosis and metastasis. Malignant melanoma proliferates more readily in comparison with any other types of skin cancer. In the present study, the anti‑cancer effect of resveratrol on melanoma cell proliferation was evaluated. Treating A375SM cells with resveratrol resulted in a decrease in cell growth. The alteration in the levels of cell cycle‑associated proteins was also examined by western blot analysis...

A diet rich in cruciferous vegetables such as cauliflower, broccoli, and cabbage has long been considered healthy, and various epidemiological studies suggest that the consumption of cruciferous vegetables contributes to a cancer-protecting diet. While these vegetables contain a vast array of phytochemicals, the mechanism by which these vegetables counteract cancer is still largely unresolved. Numerous in situ studies have implicated indole-3-carbinol, a breakdown product of the glucosinolate indole-3-ylmethylglucosinolate, as one of the phytochemicals with anti-cancer properties...

Dietary compounds that possess the properties of altering epigenetic processes are gaining popularity as targets for cancer prevention studies. These compounds when administered at optimal concentrations and especially in combination can have enhanced effects in cancer prevention or therapy. It is important to study the interaction of two or more compounds in order to assess their role in enhancing prevention. Genistein (GEN), found in soy, has been extensively studied for its role as an epigenetic modifier especially as a DNA methyltransferase (DNMT) inhibitor and sulforaphane (SFN), found in cruciferous vegetables, is known as a histone deacetylase (HDAC) inhibitor...

Non-bacterial thrombotic endocarditis (NBTE) is a well-described phenomenon associated with malignancies due to hypercoaguable state. In the setting of pancreatic cancer, NBTE is more commonly diagnosed postmortem. We describe a case of a man who was diagnosed with pancreatic carcinoma after incidental finding of NBTE. Imaging incidentally revealed multiple strokes, bilateral renal and splenic infarcts, while subsequent workup for cardioembolic source demonstrated a 1.1×0.7 cm mitral valve vegetation. As multiple blood cultures were sterile and patient lacked clinical signs of infection, an underlying malignancy was suspected...

Skin cancer incidence is rapidly growing over the last decades and is generally divided into malignant melanoma and non-melanoma (NMSC) with the latter being subdivided into squamous (SCC) and basal cell carcinoma (BCC). Among them, melanoma is the most aggressive type with high mortality rates. On the other hand, aberrant gene expression is a critical step towards malignant transformation. To this end, epigenetic modifications like changes in DNA methylation patterns and miRNA expression profile as well as histone modifications are all capable of inducing an altered gene expression profile involved in various cellular cascades including cell cycle, proliferation and apoptosis...

Carotenoids are naturally occurring pigments found in most fruits and vegetables, plants, algae, and photosynthetic bacteria. Humans cannot synthesize carotenoids and must ingest them in food or via supplementation. Carotenoids have a range of functions in human health. They primarily exert antioxidant effects, but individual carotenoids may also act through other mechanisms; for example, β-carotene has a pro-vitamin A function, while lutein/zeaxanthin constitute macular pigment in the eye. The benefit of lutein in reducing progression of age-related macular eye disease and cataracts is strengthening; an intake recommendation would help to generate awareness in the general population to have an adequate intake of lutein rich foods...

BACKGROUND: There are a few epidemiological studies that (1) link increased ambient air pollution (AP) with an increase in lung cancer incidence rates and (2) investigate whether residing in green spaces could be protective against cancer. However, it is completely unclear whether other forms of cancer are also affected by AP and if residential green spaces could lower cancer incidence rates in general. Therefore, the objective was to estimate whether AP and green space are associated with several cancer types...

Numerous studies indicate that diets with a variety of fruits and vegetables decrease the incidence of severe diseases, like diabetes, obesity, and cancer. Diets contain a variety of bioactive compounds, and their features, like diverge scaffolds, and structural complexity make them the most successful source of potential leads or hits in the process of drug discovery and drug development. Recently, novel serine protease dipeptidyl peptidase-4 (DPP-4) inhibitors played a role in the management of diabetes, obesity, and cancer...

p-CA is a naturally occurring phenolic acid present in most plants and in all commonly consumed vegetables and fruits. Here we demonstrated the anti-cancer effect of the food borne phytochemical p-CA both in vitro and in vivo models of colon cancer using growth rate and tumor incidence as endpoints. Glucose regulated protein (GRP78) induction and UPR activation plays a key role in oncogenic progression, therefore increased dependence of cancer cells on these UPR signaling pathways for survival can be exploited for anti-cancer research...

There is increasing evidence for the interaction between gut microbiome, diet, and health. It is known that dysbiosis is related to disease and that most of the times this imbalances in gut microbial populations can be promoted through diet. Western dietary habits, which are characterized by high intakes of calories, animal proteins, saturated fats, and simple sugars have been linked with higher risk of obesity, diabetes, cancer, and cardiovascular disease. However, little is known about the impact of dietary patterns, dietary components, and nutrients on gut microbiota in healthy people...

Vegetables and fruits contain non-provitamin A (lycopene, lutein, and zeaxanthin) and provitamin A ( β -carotene, β -cryptoxanthin, and α -carotene) carotenoids. Within these compounds, β -carotene has been extensively studied for its health benefits, but its supplementation at doses higher than recommended intakes induces adverse effects. β -Carotene is converted to retinoic acid (RA), a well-known immunomodulatory molecule. Human interventions suggest that β -carotene and lycopene at pharmacological doses affect immune functions after a depletion period of low carotenoid diet...
