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.
In research published in Scientific Reports , 1 investigators focused on mesenchymal stem cells (MSCs), known for their potential in treating cell defects and regulating immune responses. In the lab, they labelled RNA molecules with fluorescent markers, enabling them to easily locate them within individual cells.
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 epigenome (meaning ‘above the genome’) is a system of reversible marks regulating how the DNA is read, translated and used. 2 Additionally, the epigenetic editing toolkit allows for precise temporal regulation. What is epigenetic editing? The clinic is the natural next step for epigenetic editing.
In the paper, researchers from Johns Hopkins University and elsewhere found a natural long-form transactivating CRISPR RNA (tracr-L) in Streptococcus pyogenes that functions to downregulate its endogenous CRISPR-Cas9 system. But altering the tracr-L with genetic engineering to make it function more like a guide RNA increased CRISPR-Cas9 cuts.
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*.

1 The research, supported by the National Institutes of Health, centres on a cellular chaperone protein called GRP78, responsible for regulating protein folding within cells. In the top row, human lung cancer cells were engineered to over-express GRP78 in the nucleus. Previous studies led by Dr Amy S.
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.

Back in 2018, researchers tested a broad-spectrum antiviral candidate called remdesivir/VEKLURY, which acts as a nucleotide decoy to get incorporated into the viral RNA genome and stop viral polymerase. But targeting Ebola virus polymerase has proven tough. To our knowledge, this is the first time GSPT1 has been linked to viral infection.”
The core of the CRISPR immune response is a guide RNA (gRNA) that binds to a CRISPR-associated (Cas) protein. This article provides a summary of the major CRISPR systems, 2 including the naturally occurring CRISPR-Cas9, -Cas12, and -Cas13 systems, as well as base editors, prime editors, and the recently uncovered bridge RNA system.
Kamal Nahas highlights the biological limits on cell division speed and explores how we might engineer cells to grow faster. coli to clone DNA, engineering this microbe to divide more quickly would greatly accelerate research. Proteins are colored blue and RNA molecules are colored orange and yellow.
A gene encoding green fluorescent protein was placed alongside one of the three promoters, and as the engineered cells cycled from one gene to the next, they blinked between green—dark—green—dark. The RNA Exporter , which was developed by Felix Horns and others in my lab, is one example. And he was also in Heidelberg.
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.

But for a recent paper out of Nanjing, China, researchers engineered another enzyme and showed that, when mixed with FAST-PETase, the two worked together to break down plastic twice as fast as the Texas enzyme alone. Because it turns out that at least half of them , in humans, also bind to RNA molecules. RNA export systems.

Most people would take the two CRISPR gene-editing components (a Cas9 protein and guide RNA), package them up inside of a virus, and then inject the viruses into the skulls of mice. Genetic engineering can be used to eradicate mosquitoes in two ways: Through gene drives or the “sterile insect technique.” Stahl et al.

Scientists are already building a model that can, for example, look at which RNA molecules are expressed in a cell at t=0 and predict how those molecules will change at t=1. SeqFISH, developed by Long Cai’s group at Caltech, maps the spatial positions of thousands of RNA, DNA, or protein molecules within single cells.
The company and MiNA Therapeutics Limited announced a global research collaboration to develop novel drug candidates using MiNA’s proprietary small activating RNA (saRNA) technology platform. The company announced the acquisition of Protomer Technologies Inc.,
This method uses a chemical to inhibit DNA methylation, along with a genetic modification to activate expression of key transcription factors which regulate the expression of many other genes, inducing the cells to differentiate to an oogonia-like state. Human and mouse cells also have several differences in gene regulation.
Remdesivir and other broad-spectrum antivirals work by jamming up RNA-dependent RNA polymerase (RdRp), an enzyme that nearly all RNA viruses use to replicate their genomes. Other efforts to build broad-spectrum antivirals have focused on another conserved feature of viruses: double-stranded RNA.
DNA and RNA molecules are also built from exclusively right-handed nucleic acids. As Richard Dawkins said of biological wheels : “the engineering solution can be seen in plain view, yet [it is] unattainable in evolution because it lies [on] the other side of a deep valley.”
Codon Digest is my weekly roundup of research, news, and industry highlights about engineered biology. These microbes were engineered to express tumor antigens that could “elicit T cells that were licensed by the commensal immune program but specific for a tumor,” including both CD4+ and CD8+ T cells, according to the study.

ESM is a protein language model that captures certain aspects of protein structure and function, for example, but is blind to DNA or RNA-level features that drive cell behavior. Evo 2 was trained on DNA sequences but can make predictions about myriad aspects of biology, including RNA stability and protein structures.
And finally, people intent on causing harm could engineer pathogens to become more dangerous. But DNA screening tools can't simply flag any sequence that is similar to a potentially dangerous virus because the public databases also include engineered sequences comprising DNA sequences created from multiple different organisms.
