An epigenetic signature characterizes monozygotic twins

An international study has identified a characteristic epigenetic marking pattern of the somatic cells of monozygotic twins that opens up avenues for research on how twins originate and allows us to detect whether a person is a monozygotic twin. More information at:

CRISPR therapy cures first genetic disorder inside the body

For the first time, researchers appear to have effectively treated a genetic disorder by directly injecting a CRISPR therapy into patients’ bloodstreams — overcoming one of the biggest hurdles to curing diseases with the gene editing technology. Read full (audio) story:

Researchers Find Common Denominator Linking All Cancers

All cancers fall into just two categories, according to new research from scientists at Sinai Health, in findings that could provide a new strategy for treating the most aggressive and untreatable forms of the disease. Read full article (in spanish): National Geographic España

New evidence of paternal and maternal epigenetic transmission to offspring

Two recent studies have identified some of the environmental factors that influence epigenetic inheritance. The first of them, published in the journal Developmental Cell on March 8, has determined that the paternal diet produces epigenetic changes in sperm proteins that can affect the development of the offspring. The second, published in PNAS on March 23, has found that certain factors, such as maternal age…

International team creates first chimeric human-monkey embryos

Juan Carlos Izpisua Belmonte’s research team, in collaboration with Chinese scientists, has managed to create chimera embryos with human and monkey cells and cultivate them for 19 days. The research, which has received some criticism due to the ethical implications of chimera generation, has demonstrated the potential of human stem cells to contribute to different cell types in chimera embryos and provides new information…

Researchers identify genetic factors related to the development of pregnancy and the onset of labor

An evolutionary study by researchers at Buffalo University and the University of Chicago has linked a gene, HAND2, to the onset of childbirth in humans. The work suggests that this gene may also be related to other relevant gestational processes, such as mother-fetus communication during pregnancy. Full article available in Genética Médica News.

Spanish researchers developed a drug that selectively removes metastatic stem cells

Spanish researchers developed a drug that selectively removes metastatic stem cells. The specialists of the Network Biometric Research Center: Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN) have taken a step forward in the fight against cancer. And they have communicated it to public opinion. The complete news in this link.
