REVIEW
Sin-Aye Park, Young-Joon Surh
The tumor microenvironment provides a niche in which cancer cells and their surrounding stromal cells reside and in which their interactions occur. The cross talk between cancer and stromal cells in the tumor microenvironment promotes many biological processes to support cancer cell growth, invasion, angiogenesis, and metastasis. Recently, not only cancer cells but also multiple types of surrounding stromal cells, including endothelial cells, immune cells, and fibroblasts in the tumor microenvironment, have been recognized to be attractive targets for reducing resistance to anticancer therapy and tumor recurrence...

Lectins are proteins of a nonimmunoglobulin nature that are capable of specific recognition of and reversible binding to the carbohydrate moieties of complex carbohydrates, without altering the covalent structure of any of the recognized glycosyl ligands. They have a broad range of biological activities important for the functioning of the cell and the whole organism and, owing to the high specificity of reversible binding to carbohydrates, are valuable tools used widely in biology and medicine. Lectins can be produced by many living organisms, including basidiomycetes...

Guido Gainotti
In semantic tasks, sex-related categorical differences, in the form of better processing of fruits and vegetables by women and of artifacts (human-made objects) and animals by men, have been reported both in healthy participants and in brain-damaged patients. Researchers' interpretation of these sex-related categorical asymmetries has, however, been controversial, being connected with the more general (innatist versus experience-dependent) interpretations that had been given of the mechanisms subsuming the categorical organization of the brain...

To feed the world's growing population, increasing the yield of crops is not the only important factor, improving crop quality is also important, and it presents a significant challenge. Among the important crops, horticultural crops (particularly fruits and vegetables) provide numerous health compounds, such as vitamins, antioxidants, and amino acids. Essential amino acids are those that cannot be produced by the organism and, therefore, must be obtained from diet, particularly from meat, eggs, and milk, as well as a variety of plants...

Cancer is one of the major causes of death in humans. Of all cancers, 19% are attributed to exposure to environmental chemical carcinogens. Dietary polyphenols from teas, vegetables, fruits, and many others exhibit multiple activities against cancers. Exposure to environmental carcinogens such as ultraviolet B (UVB), polycyclic aromatic hydrocarbons (PAHs), and heavy metals has been demonstrated to cause cancer in humans. In this article, we specifically select UVB, PAHs, and metals as representative of three types of environmental carcinogens: physical, organic, and inorganic, respectively...

The ability of some crops to accumulate selenium (Se) is crucial for human nutrition and health. Selenium has been identified as a cofactor of the enzyme glutathione peroxidase, which is a catalyzer in the reduction of peroxides that can damage cells and tissues, and can act as an antioxidant. Plants are the first link in the food chain, which ends with humans. Increasing the Se quantity in plant products, including leafy and fruity vegetables, and fruit crops, without exceeding the toxic threshold, is thus a good way to increase animal and human Se intake, with positive effects on long-term health...

Type-2 diabetes mellitus (T2DM) is an endocrine disease related to impaired/absent insulin signaling. Dietary habits can either promote or mitigate the onset and severity of T2DM. Diets rich in fruits and vegetables have been correlated with a decreased incidence of T2DM, apparently due to their high polyphenol content. Polyphenols are compounds of plant origin with several documented bioactivities related to health promotion. The present review describes the antidiabetic effects of polyphenols, specifically related to the secretion and effects of insulin and glucagon-like peptide 1 (GLP1), an enteric hormone that stimulates postprandial insulin secretion...

Ricardo Martínez-García, Corina E Tarnita
The social amoeba Dictyostelium discoideum has been recently suggested as an example of bet-hedging in microbes. In the presence of resources, amoebae reproduce as unicellular organisms. Resource depletion, however, leads to a starvation phase in which the population splits between aggregators, which form a fruiting body made of a stalk and resistant spores, and non-aggregators, which remain as vegetative cells. Spores are favored when starvation periods are long, but vegetative cells can exploit resources in environments where food replenishes quickly...

Cycling Dof Factor (CDF) transcription factors (TFs) are involved in multiple processes related to plant growth and development. A member of this family, CDF3, has recently been linked in Arabidopsis to the regulation of primary metabolism and abiotic stress responses, but its role in crop production under stress is still unknown. In this study, we characterized tomato plants overexpressing the CDF3 genes from Arabidopsis and tomato and analyzed their effects on growth and yield under salinity, additionally gaining deeper insights into the molecular function of these TFs...
