X inactivation turns off entire chromosomes, whereas imprinting turns off only specific genes. How do these processes work, and why do they often produce similar results? Upon examining their ...

Genomic imprinting, an epigenetic gene-marking phenomenon that occurs in the germline, leads to parental-origin-specific expression of a small subset of genes in mammals. Imprinting has a great ...

Researchers developing Australia’s first mRNA Covid vaccine say they may have solved the “immune imprinting” issue that has contributed to the declining effectiveness of boosters as the ...

The mechanism behind this phenomenon, known as genomic imprinting, is determined by DNA modifications during egg and sperm production. Some of our genes can be expressed or silenced depending on ...

“This paper shows that we share a common genetic imprinting mechanism which has been active for about 150 million years despite the differences in reproductive strategies between marsupials and ...
