The dynamic behaviour of RNA transcripts, the regulation and modification of proteins, the lipid composition of membranes, the structural organisation of cells and the spatial context of tissues all play critical roles in disease progression and therapeutic response.

Plastic leaves do not emit organic signals and contain no DNA, so any mimicry could imply some kind of primitive vision. Such vascular differences are governed by auxin, a plant hormone that regulates leaf venation and shape. Martin Bourdev is an engineer at Amgen Thousand Oaks supporting antibody drug production.
Certain CRISPR components can add short DNA sequences from the genomes of defeated viruses into the bacterium’s own genome, creating a type of protective “memory.” If the same virus invades the cell a second time, the gRNA’s spacer sequence will bind to the matching viral DNA sequence, then be cut by the Cas protein.
For example, cloning DNA molecules and inserting them into cells — a process required for basically all experiments in molecular biology — takes up to a week of work. Perhaps you’ve seen this chart before, which shows the falling costs of DNA sequencing over the last two decades. If we could get E.
The new method uses a combination of prime editing, which can directly make a wide range of edits up to about 100 or 200 base pairs, and newly developed recombinase enzymes that efficiently insert large pieces of DNA thousands of base pairs in length at specific sites in the genome.
At Alkermes , our interdisciplinary team of protein engineers, immunologists, pharmacologists, and analytical scientists is investigating the biology of several immunomodulatory cytokines including IL-12 and IL-18 to develop novel versions of these molecules with the goal of harnessing their therapeutic potential.
Cas9 ancestor engineered into a compact genome editing tool By Tom Ulrich May 14, 2025 Breadcrumb Home Cas9 ancestor engineered into a compact genome editing tool Researchers adapt a compact RNA-guided enzyme from bacteria for a variety of DNA editing tasks in human cells.
The reasons for this are multifaceted, including concerns over the safety of directly altering DNA sequences and subsequent regulatory restrictions that have arisen as a result. The epigenome (meaning ‘above the genome’) is a system of reversible marks regulating how the DNA is read, translated and used.
Gene therapy research is exciting and full of promise, but because of the risks involved, it’s also highly regulated, requiring an institutional biosafety committee (IBC) to provide additional oversight and risk assessment. What do the Regulations Say about IBC Review? What Does an IBC Review?
Columbia Engineering researchers report that they have developed a “cloaking” system that temporarily hides therapeutic bacteria from immune systems, enabling them to more effectively deliver drugs to tumors and kill cancer cells in mice.

At the dining table. More are still unfolding.
These microscopic particles, which are smaller than 100 nanometers, can be engineered to deliver drugs to specific targets with precision. This approach targets the fundamental instructions within a cell's DNA, either by correcting faulty genes or introducing entirely new ones to combat disease.

To find out, we need to understand how this system is regulated, and what exactly RBM3 does in the cells. They wanted to find out how RBM3 is regulated by temperature — these kinds of proteins are known as ‘cold-shock’ proteins. Curiously, these followed a theme in molecular function: the regulation of splicing*.
2 Structure and function of AAV capsids in gene therapy Wild-type AAV is composed of a protein shell (capsid) that contains a single-stranded DNA genome encoding proteins involved in viral replication, structure and assembly. Therefore, vectors based on these serotypes may enable targeted gene delivery and optimal transduction efficiency.
These hair clip-like molecules clamp onto DNA, thereby turning many genes on and off. That can be a good thing: for example, when determining inherited traits and regulating critical cell functions. Or a bad thing: for example, when increased expression of certain genes contributes to the formation of cancer.
Transforming Genomics Research Next-generation sequencing (NGS) enables comprehensive genome sequencing and has transformed genomics research, offering vastly improved capabilities for analyzing DNA and RNA in a high-throughput and cost-effective manner. We have built a global, full-service CRO powered by intuitive end-to-end technology.

Obesity due to POMC, PCSK1 or LEPR deficiency are ultra-rare diseases caused by variants in POMC, PCSK1 or LEPR genes that impair the MC4 receptor pathway, which is a pathway in the hypothalamus that is responsible for regulating hunger, energy expenditure and consequently body weight.

The regulations also explain that this trait can be demonstrated via appropriate laboratory tests or adequately controlled clinical data. Additionally, six of these comments came from the same organization (Integrated DNA Technologies). However, only 40 of these comments have been posted to the docket for public review.
Two years ago, a friend took me out to coffee in Boston and said, “I think we can engineer an organism to terraform Mars.” The feat could be achieved with something as direct as engineering a microbe that can survive on the Martian surface, and then letting it grow and spread over the planet. (* = probably.)
Kamal Nahas highlights the biological limits on cell division speed and explores how we might engineer cells to grow faster. However, they plod along as they clone plasmids—the loops of DNA that biologists use to manipulate and study organisms—because propagating them relies, in part, on the pace at which cells grow and divide.
Backyard astronomers discovered 42 new planets in 2012 , hobbyist paleontologists discovered the world’s largest dinosaur footprint near the Yorkshire coast in 2021, and Sebastian himself open-sourced protocols that make it easier for scientists to engineer plants. And what genes will I need to engineer these flowers?
The NOD-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome is a central regulator of innate immunity, essential for processing and release of interleukin-1β and pyroptotic cell death. Mice also contain plasma esterase (Ces1c) activity which is absent in humans.
Regulators traditionally want to see a single, stable, well-characterized drug before giving the green light for it to be tested in a clinical trial, not dozens of different viruses; let alone ones that are best found in unappealing places like sewage , hospital waste, or bird poop.
But data is accumulating to suggest it matters a lot: resolving one variant from another – and understanding what drives their relative concentrations – may be just as important in biology as regulation of gene expression. Yet most modern proteomic protocols cannot readily distinguish thrombin from prothrombin or C3b from C3.
This is Codon Digest, a weekly roundup of research papers, news articles, and industry highlights about engineered biology. But now, by studying DNA extracted from microbes in the blood of almost 10,000 healthy people, this paper shows that there is no such thing. Read Transcription factors bind to DNA and control gene expression.
To combat these threats, genetic engineers are making bananas that fend off fungi or ripen slower than natural varieties. This gene is regulated, in turn, by a small arsenal of other proteins from the MaMADS family. ( Friedman’s engineered bananas stay yellow for more than a month after being plucked from a tree.

The country has now ruled that the gene-edited bananas are exempt from GMO regulations because they do not carry additional DNA sequences, and so they will not have to pass through strict safety testing. Genetic engineering can be used to eradicate mosquitoes in two ways: Through gene drives or the “sterile insect technique.”

When these engineered cells are then placed into a mouse, one can use ultrasound to “hear” the cells as they move around. For more than a century, scientists thought of gas vesicles as little more than a natural curiosity and, later, as a way for microbes to regulate buoyancy. coli and human cells. But light has limits.
in physics at Princeton University, he had a remarkable idea: What if it were possible to build a circuit out of DNA, rather than electronics, and use it to “program” a living cell? In 1997, as Michael Elowitz was studying for a Ph.D. Elowitz had created cells that acted as living oscillators. And he was also in Heidelberg.
