The U.S Food and Drug Administration (FDA) has approved a new drug combination for men with metastatic, castration-resistant prostate cancer (mCRPC) and certain DNA repair gene mutations, widening treatment options for this large patient population.

The androgen-receptor inhibitor enzalutamide plus the PARP inhibitor talazoparib can now be used as first-line treatment for mCRPC patients who have homologous recombination repair (HRR) gene alterations.

Reactive oxygen species (ROS) are important in regulating normal cellular processes whereas deregulated ROS leads to the development of a diseased state in humans including cancers. Several studies have been found to be marked with increased ROS production which activates pro-tumorigenic signaling, enhances cell survival and proliferation and drives DNA damage and genetic instability. However, higher ROS levels have been found to promote anti-tumorigenic signaling by initiating oxidative stress-induced tumor cell death. Tumor cells develop a mechanism where they adjust to the high ROS by expressing elevated levels of antioxidant proteins to detoxify them while maintaining pro-tumorigenic signaling and resistance to apoptosis.

The biological roots of autism continue to perplex researchers, despite a growing body of studies looking at an increasing array of genetic, cellular and microbial data. Recently, scientists have homed in on a new and promising area of focus: the microbiome. This collection of microbes that inhabit the human gut has been shown to play a role in autism, but the mechanics of this link have remained awash in ambiguity.

Taking a fresh computational approach to the problem, a study published today, June 26, in Nature Neuroscience sheds new light on the relationship between the microbiome and autism. This research—which originated at the Simons Foundation’s Autism Research Initiative (SFARI) and involved an innovative reanalysis of dozens of previously published datasets—aligns with a recent, long-term study of autistic individuals that centered on a microbiome-focused treatment intervention. These findings also underscore the importance of longitudinal studies in elucidating the interplay between the microbiome and complex conditions such as autism.

“We were able to harmonize seemingly disparate data from different studies and find a common language with which to unite them. With this, we were able to identify a microbial signature that distinguishes autistic from neurotypical individuals across many studies,” says Jamie Morton, one of the study’s corresponding authors, who began this work while a postdoctoral researcher at the Simons Foundation and is now an independent consultant. “But the bigger point is that going forward, we need robust long-term studies that look at as many datasets as possible and understand how they change when there is a [therapeutic] intervention.”

This is older but this is just the tip of the iceberg. China is rumored to be working on genetic engineering to create “super soldiers” and they’re one country that isn’t stopped by ethics concerns. In the Prime TV series “The peripheral” it has something similar and I don’t want to spoil it beyond that. I think there’s a Vin Diesel movie called Blood Shot where he’s made into a super soldier. It’s a shame that this is used for warfare but the plus side is it’ll, some of the tech, will make its way down to civilian life such as the Internet did.

In a recent study published in the journal Nature Medicine, researchers pursued one-time cures for hypertrophic cardiomyopathy (HCM). They used a previously constructed murine model of HCM, designated as R403Q-129SvEv, to evaluate two different genetic therapies, as follows:

I) an adenine base editor (ABE8e)

Ii) a potent Cas9 nuclease delivered by an adeno-associated virus (AAV) vector.

In-cell engineering can be a powerful tool for synthesizing functional protein crystals with promising catalytic properties, show researchers at Tokyo Tech. Using genetically modified bacteria as an environmentally friendly synthesis platform, the researchers produced hybrid solid catalysts for artificial photosynthesis. These catalysts exhibit high activity, stability, and durability, highlighting the potential of the proposed innovative approach.

Protein crystals, like regular crystals, are well-ordered molecular structures with diverse properties and a huge potential for customization. They can assemble naturally from materials found within cells, which not only greatly reduces the synthesis costs but also lessens their environmental impact.

Although protein crystals are promising as catalysts because they can host various functional molecules, current techniques only enable the attachment of small molecules and simple proteins. Thus, it is imperative to find ways to produce protein crystals bearing both natural enzymes and synthetic functional molecules to tap their full potential for enzyme immobilization.

Georgia Tech researchers have transformed a standard BBQ lighter into a delivery system that uses an electric spark to boost DNA vaccines — and it could help increase global access to a cheap, powerful new vaccine technology.

mRNA vs. DNA vaccines: DNA vaccines deliver a bit of genetic code that tells cells in the body to make a protein from a specific virus or bacteria. That triggers the immune system to create antibodies against that protein that will protect you if you’re ever infected by that particular pathogen.

This is exactly how mRNA vaccines work, too, and just like mRNA vaccines, DNA-based shots are relatively cheap to produce and easy to change to make new vaccines — but the way mRNA and DNA vaccines get their genetic instructions into cells is different.

Recent collaborative research conducted by scientists in the United States and China unveils the mechanism through which a fertilized egg cell, also known as a zygote, triggers a ‘reset’, enabling the newly formed embryo can develop according to its own genetic program. The study was recently published in the journal Nature.

It has been known for some time that the genome of a newly fertilized egg cell is inactive and has to be woken up, said Richard Schultz, research professor at the University of California, Davis, School of Veterinary Medicine and a corresponding author on the paper. This step is called zygote genome activation.

“For the embryo to develop, the oocyte/egg has to lose its identity and does so by making new stuff,” Schultz said. “We now know the first steps in how this transition occurs.”
