Enzymatic modification of arabinoxylans from soft and hard Argentinian wheat inhibits the viability of HCT-116 cells.

Dietary fiber plays an important role in the prevention of colorectal cancer, and arabinoxylans are an important source of this in grains, with some studies reporting the inhibition of cancer cell growth. However, very few studies have been conducted on this, and most previous studies have used oligosaccharides derived from arabinoxylans of specific molecular weight. The aim of this work is to extract, isolate, and analyze arabinoxylans from two different Argentinian genotypes of wheat (hard and soft) and study if they have the capacity to decrease the cellular viability of a colon cancer line (HCT-116).

MeCP2 Deficiency Disrupts Kainate-Induced Presynaptic Plasticity in the Mossy Fiber Projections in the Hippocampus.

Methyl cytosine binding protein 2 (MeCP2) is a structural chromosomal protein involved in the regulation of gene expression. Mutations in the gene encoding MeCP2 result in Rett Syndrome (RTT), a pervasive neurodevelopmental disorder. RTT is one of few autism spectrum disorders whose cause was identified as a single gene mutation.

Differential effects of tianeptine on the dorsal hippocampal volume of rats submitted to maternal separation followed by chronic unpredictable stress in adulthood.

Early maternal separation (MS) may produce lasting effects in the dorsal hippocampus (DH) that can change its response to chronic stress in adulthood. Chronic stress affects DH morphology and function, but tianeptine (an anti-depressant) can reverse the stress-induced morphological impairments. Morphologic alterations of hippocampus can affect contextual memory.
