Wheatgrass is a nutrient-rich type of young grass in the wheat family. It's sold as a dietary supplement in tablet, capsule and liquid forms. Wheatgrass is often used for juicing, or added to smoothies or tea.ome proponents tout wheatgrass as a treatment for cancer, anemia, diabetes, constipation, infections, skin conditions, ulcerative colitis and joint pain, among other health concerns. However, there are few research studies about wheatgrass, so it's difficult to assess such health claims.
Genomic imprinting is an example of epigenetic inheritance in which differences in gene function depend on whether the allele was inherited from the mother or father. Many disorders appear to involve epigenetic alterations to imprinted genes. Genes involved in imprinting play important roles in both preâ and postânatal growth and neurodevelopment. Imprinting disorders include several childhood genetic disorders such as PraderâWilli, Angelman and BeckwithâWiedemann syndromes, as well as several types of cancer including Wilms tumour. Recent evidence suggests a correlation between assisted reproductive technologies (ART) and imprinting disorders, a phenomenon requiring more inâdepth studies as the prevalence of ART is increasing.
Genomic imprinting, also referred to as gametic or parental imprinting, was discovered almost simultaneously by two laboratories in 1984. Prior to the publications of McGrath and Solter (1984) and Surani et al.(1984), conflicting results existed about whether both parental genomes were required for normal development.a Aa Aa. In the majority of cases, two copies of each chromosome â and therefore, two copies of each gene â arrive in every fertilized egg. However, in some cases, one of the genes within a pair is somehow switched off; this occurs because of the process known as imprinting.
