A new study on mice shows great promise for treating colon cancer – a simple genetic tweak can turn colorectal cancer cells into healthy tissue in a matter of days.
In the quest to understand what are the crucial differences between human and chimpanzee brains, scientists have isolated a stretch of DNA, once thought to be “junk”, near a gene that regulates brain development in mice. The engineered mouse embryos grew significantly larger brains. Those which received human brain DNA strands had 12% larger brains than those bred with chimp brain DNA. Research like this, though ethically controversial, might help identify which DNA sequences give a brain human characteristics, but also aid in findings treatment or cures for brain diseases like Alzheimer’s.
We’ve come a long way since the first mammal, a sheep named Dolly, was cloned. Now, a lab in South Korea will clone your dog for around $100,000; so far, they’ve cloned 400 pets since 2006. Cloning is still tabu in many parts of the world, but it’s a process which is no longer reserved for the future – it’s happening
Genetic diversity is essential to our survival, but its exactly the huge variance in genetic information that makes all so sought for personalised treatment so difficult. And you don’t need to look at an entire population or even two different people to experience the power of diversity. It’s enough to look inside your own, personal genome since you carry two
A massive independent genetic survey sought to replicate the findings of a 20 year old controversial study which identified a stretch on the X chromosome as being linked with homosexuality. The latest findings, which took into account the genetic makeup of a staggering 409 pairs of gay siblings, confirm the initial reports and further boost the idea that homosexuality is also influenced by
It’s common knowledge that babies born out of tall parents will most likely grow to be just as tall, but it’s only recently that scientists report finding most of the genes responsible for height. Information like this could prove to be useful in diagnosing genetic growth deficiencies or, in the not so distant future, genetic manipulation to enhance growth in height. Short
Researchers at the Max Planck Institute of Immunobiology and Epigenetics (MPI-IE) re-activated the expression of an ancient gene in mice. To their surprise, the gene in question which is dormant in all mammalian species caused the mice to develop fish-like thymus. The thymus is an organ of paramount importance to the adaptive immune system, but in this particular instance, the thymus produced
Researchers at the Sanford-Burnham Medical Research Institute (Sanford-Burnham) have found a chemical switch that both regulates the generation of new neurons from neural stem cells and the survival of existing nerve cells in the brain. Postmortem examination of the brains of Alzheimer’s patients and stroke victims found the switch that shuts off the signals was in abundance. With this in
Mice in the control group refused to drink alcohol When a certain gene was deactivated, they started preferring alcohol over water Researchers stress that human alcoholism depends much more on environmental and personal factors Researchers have discovered a gene that regulates alcohol consumption; when this genes becomes faulty, it makes humans more prone to excessive drinking. They have also
Scientists have discovered an atypical gene that is thought to be crucial for the generation of new neurons in the brain, a process called neurogenesis. The discovery and further study of the gene might help scientists better understand how neurodegenerative diseases such as Alzheimer’s affect the brain and, in term, how to address them. New neurons are born through a
A study has shown that genetically modified salmon that breed with wild trout can produce a fast-growing, competitive fish that not only screws around with the local ecosystem, but because it also alters the fish genome in ways which cannot be anticipated. What do you get when you cross a genetically modified salmon and wild brown trout? Well, something which
