Gene drive is both a promising and disturbing technology. It allows us to engineer a stretch of DNA that, once inserted in a specific location in an organism’s genome, will convert other versions of the gene so that they also carry the insert. Once started in a population, gene drive will convert the entire population within a relatively short number of generations.

That’s promising, in that it opens the door to editing mosquitos to cause sterility to spread through a population, eliminating the spread of diseases and a fair bit of itching. But it’s also a genie that, once out of the bottle, appears to be impossible to put back—and hence is disturbing. But so far, there has been a small consolation: it has only been shown to work in insects.

Now, a large research team at the University of California, San Diego, has managed to get it working in mice. Sort of. It turns out that the efficiency is much lower. While the gene drive DNA is inherited at rates well above normal Mendel-style inheritance, it’s nowhere near as effective as in insects, and it’s not clear we know how to fix it.

Is Gene ready to be the Patrick Swayze to Courtney’s Jennifer Grey? (Spoiler alert: No, no he is not.) The middle Belcher child receives an offer he can absolutely refuse in this exclusive sneak peek from Sunday’s Bob’s Burgers (Fox, 8:30/7:30c) when Courtney’s dad requests that he fill in for her partner at an upcoming roller dance pairs competition.

What happens next is an act of betrayal that no one will see coming. Well, no one except for those who read the official synopsis for the episode. Spoilers ahead:

Gene is livid when his best friend Alex (guest-voice Thomas Middleditch) ditches him to be Courtney’s (guest-voice David Wain) roller dancing partner. Teddy, Linda and Bob let their imaginations get the best of them when they discover someone stalking the restaurant in the all-new ‘Roller? I Hardly Knew Her!’ episode of Bob’s Burgers.

Complex organisms have complex genomes. While bacteria and archaea keep all of their genes on a single loop of DNA, humans scatter them across 23 large DNA molecules called chromosomes; chromosome counts range from a single chromosome in males of an ant species to more than 400 in a butterfly.

There have been indications that chromosomes matter for an organism’s underlying biology. Specialized structures within them influence the activity of nearby genes. And studies show that areas on different chromosomes will consistently be found next to each other in the cell, suggesting their interactions are significant.

So how do we square these two facts? Chromosome counts vary wildly and sometimes differ between closely related species, suggesting the actual number of chromosomes doesn’t matter much. Yet the chromosomes themselves seem to be critical for an organism’s genome to function as expected. To explore this issue, two different groups tried an audacious experiment: using genome editing, they gradually merged a yeast’s 16 chromosomes down to just one giant molecule. And, unexpectedly, the yeast were mostly fine.

OZY brings to you Medical Breakthroughs, a series about transformative cures and approaches — and the people behind them.

Brian O’Roak loves Gaelic football, a fast-paced game with 15 players; a round ball that can be carried, kicked or passed; and a bunch of complex rules. Which makes perfect sense when you discover that O’Roak has managed some of the most complicated studies of autism genetics to date, involving the sequencing and analysis of DNA samples from thousands of individuals. “I was looking for something that was really hard, but potentially with a path forward,” he says, recalling the moment in grad school when he decided to focus on autism research.

At Oregon Health and Science University (OHSU) in Portland, the 37-year-old assistant professor of molecular and medical genetics is still wrestling with big, complex challenges. Known for his pioneering work on the genetic risk factors for autism, a neurodevelopmental disorder that affects about 1 in 68 children, O’Roak is now investigating what those genes are doing as the brain develops. The ultimate goal? To devise gene therapies that could fix the mutations leading to autism and restore healthy brain development.

O’Roak’s work — for which he received the BRAINS (Biobehavioral Research Awards for Innovative New Scientists) young investigator award from the National Institute of Mental Health last fall — involves taking stem cells from human patients with autism and using new technology to coax them into becoming tiny brains-in-a-dish called organoids. O’Roak uses a 3D printer to create a scaffold on which the stem cells develop into brain-like structures in a petri dish. Watching these cells develop can provide clues to how a patient’s mutations affect the earliest stages of brain development.

O’Roak looks every bit the beer-brewing, football-playing weekend warrior, but during the week, he’s a pioneering geneticist.

“We can actually develop models in the lab that have the exact same genetic variants that are identified in individuals with autism,” O’Roak says, “and we can start to understand how those mutations affect the development of the human brain.”

For a kid who grew up in a small town in California’s Central Valley, aka America’s fruit basket, cutting-edge research wasn’t an obvious path. Raised by a single mom since second grade, O’Roak wasn’t exposed to advanced science until high school, when he became interested in biology and a teacher recommended a summer program sponsored by NASA at Southern University in Baton Rouge, Louisiana, where he worked with cells from genetically engineered obese mice.

Still unsure of what he wanted to study, O’Roak was invited to join the inaugural honors program class at Cal State Fresno, which came with a full scholarship. There, he found his way into a plant genetics and molecular biology lab (and started dating a fellow honors student who would become his wife).

From college he moved on to graduate school in genetics at Yale, completing a rotation with Matthew State, who was studying genetic mechanisms involved in psychiatric and neurodevelopmental disorders, including autism. “He [State] gave a really compelling case about how, even though neuropsychiatric or neurodevelopmental disorders were really complex, we could develop a strategy to identify risk genes that might actually let us start to unravel some of the complexities of these disorders,” O’Roak says.

Not surprisingly, he jumped into one of State’s most demanding projects. O’Roak identified individuals with autism but without any family history of the disorder, and he searched for novel mutations that had caused it to develop. Back in 2004, it wasn’t possible to sequence genes quickly and cheaply, so he looked for individuals with chromosomal abnormalities that were visible using a microscope.

Chris Mason, a postdoc in State’s lab who’s now a researcher at Weill Cornell Medicine, says of O’Roak was not only a good colleague for brainstorming about “pedigree analysis and complex genetic variation, but also complex hop variation in beer.” With his huge sideburns, rakish eyebrows and easy smile, O’Roak looks every bit the beer-brewing, football-playing weekend warrior, but during the week, says Mason, he’s a pioneering geneticist.

After finishing his Ph.D., O’Roak became a postdoctoral fellow at the University of Washington. As gene sequencing technology evolved, he used the faster method to sequence the exome — the part of the genome that codes for proteins — to identify new mutations (genetic aberrations not inherited from either parent) in children with autism. Raphael Bernier, a professor at UW, took note of O’Roak’s next-level analytic skills and was impressed that he could “work with such a massive data set,” synthesizing reams of minute details — “at such a quick pace.”

O’Roak is now marshaling those skills to help steer the largest genetic study of autism ever. OHSU is one of 25 clinical sites across the U.S. participating in SPARK, an initiative recruiting 50,000 families with autism to share genetic, behavioral and medical information with the goal of accelerating autism research. By dramatically increasing the sample size, “we think we can identify a lot of additional risk genes,” O’Roak says, while also identifying more common genetic variants that have weaker effects on autism risk.

But identifying the autism risk genes is just the beginning. “We’ve kind of just got the who in our story,” says O’Roak. “We still need to figure out the what, the where, the when and the why/how to make things better.”

Ultimately, O’Roak wants to figure out how the autism risk genes affect how the brain develops. Which brings us back to the brain organoids he’s been coaxing from stem cells of autistic patients. From these organoids, O’Roak can measure the gene activity in single cells to determine how a patient’s mutation changes the gene networks over time. He also plans to use the gene editing technology CRISPR to correct the mutation in the patient’s stem cells to see if that fixes the organoid’s growth — and points toward targeted treatments for autism.

Between his faculty responsibilities at OHSU, running a lab and parenting two young children, O’Roak is sprinting like the footballer he is. And still he finds time to make beer. In fact, Homebrew Con, a home brewers conference, came to Portland in June, and O’Roak competed in the national championship with his special home brew — the result, naturally, of a intensely complex process.

Published in EMBO Reports, the discovery was made by a Belgian team from the Université Libre de Bruxelles. Led by Alban de Kerchove d’Exaerde, the team found that the presence of the gene Maged1 is integral to the release of dopamine to the brain.

Maged1 is a little-known member of a family of genes that first came to prominence due to their presence in tumors but are also present in the brain and are altered through repeated use of cocaine.

The researchers observed that mice lacking the Maged1 gene were unresponsive to the effects of cocaine, such as euphoric feelings or loss of inhibitions. Furthermore, after repeated doses of the substance the mice did not display any of the behaviors of cocaine addiction such as seeking out places where the lab mouse would expect a cocaine reward.

When dopamine is released in either animals or humans, they are rewarded with a release of dopamine from the brain’s ventral tegmental area (VTA), which travels to other parts of the brain including the hub of the reward system – the Nucleus Accumbens (NAc).

For users of cocaine, their reward system is affected as the dopamine that usually travels from neuron to neuron is trapped in the synapse, or space between neurons, causing a build-up and amplification of dopamine which creates the feelings of being high.

Prolonged cocaine use, however, causes long-lasting changes in the brain, eventually leading to addiction. In particular, cocaine abuse affects the brain’s prefrontal cortex, which controls behaviors such as inhibitory control and emotion regulation. As a result, addicts suffer from a loss of control, poor decision-making, and drug-seeking.

After linking the connection between the presence of Maged1 addiction, the team went on to conduct further experiments to scrutinize the effect of the gene in different areas of the brain. The experiments were able to show that Maged1 controls the release of dopamine in the Nucleus accumbens.

It also found that the gene was required in the prefrontal cortex to be effective – the area of the brain most affected by cocaine abuse – and not in the neurons producing dopamine in the VTA.

Drug dependence in Europe alone affects approximately 15.5 million people, costing health services €65.7 billion per year. The team hope that their discovery allows for more targeted and effective treatments for drug dependence and pave the way for future studies into the molecular mechanisms in the brain associated with drug dependence.

A number of bacteria that infect insects have a simple and brutal way of increasing their transmission: they kill off all the male progeny of the females that they infect. There’s actually some evolutionary logic to this. The bacteria can get transmitted to the eggs of the females they infect but can’t get carried along on the sperm. That makes the male offspring a problem: they can’t spread the bacteria further, and they’ll compete with the females for food. Better to kill them off, then, just to ensure that never becomes a problem.

But it’s one thing to have something that’s a good idea conceptually and another entirely to evolve an implementation that gets the job done. How, exactly, do you go about killing one sex while leaving the other untouched?

Thanks to a lucky accident, two Swiss researchers (Toshiyuki Harumoto and Bruno Lemaitre) have identified the gene that allows one species of bacteria to kill off males. Although we don’t have all the details, it’s clear that the system leverages something that male flies need to do to cope with the fact that they only have a single copy of the X chromosome.

A GENE that makes humans eat more sugar can also lower body fat, new research suggests. Scientists have known that a version of the gene FGF21 makes people consume more carbohydrates.

They will also reveal for the first time exactly how the condition develops, in a study set to pave the way for new “personalised treatments” to prevent its onset.

The new research could help doctors understand a patient’s individual risk of developing diabetes and what they should do to reduce it.

Previous research had linked some genes to obesity, but the new findings show there to be a number of genetic variants which are now thought to lower the risk.

The study will be revealed at the annual Diabetes UK Professional Conference at The ExCel in east London on Thursday.

The research team will show how the diabetes-related genes are linked to body fat. For example, they could reveal whether a person stores fat in a “safe place” under the skin – known as subcutaneous fat – or around the belly and important organs like the liver – known as visceral fat.

Dr Hanieh Yaghootkar, lead researcher of the study and Diabetes UK research fellow at the University of Exeter, said: “I am very excited by this work. We know Type 2 diabetes is a major problem for the world because people are getting fatter.

“We also know obesity is a major risk factor for Type 2 diabetes. But we have obese and overweight people who do not have the disease and we have lean or people with a healthy weight who do.

“Understanding the mechanisms that lead to the disease means we will not have to rely on body mass indexes to prioritise people for weight loss intervention.

“It also gives us potential to find drug targets to change the genetic pathways that put people at risk of the disease.”

Dr Emily Burns, head of research communications at Diabetes UK, said: “We know obesity is one of the strongest risk factors for Type 2 diabetes, but there are many people who are overweight or obese and don’t go on to develop the condition. Research like this helps us understand why this might be at a genetic level.”

She added: “While we hope genetics will open up potential ways to protect against Type 2 diabetes in the future, there are things we can all do today. You can reduce your risk by eating a healthy balanced diet and getting regular exercise.”

The ongoing research, carried out at Exeter, London, Dundee and various centres across Europe, has studied 451,000 people to find variations in the genes that are linked to levels of body fat.

The researchers collaborated with scientists at the University of Tubingen, Germany, Leiden University in Holland and Goethe University Frankfurt, Germany.

Type 2 diabetes occurs when the body fails to make enough insulin or the insulin fails to work properly. It is estimated that 4.6 million people in the UK have diabetes – with 90 per cent of them having Type 2.

While the cause of Type 2 diabetes is poorly understood, most cases can be delayed through lifestyle changes.
