A doctor inserts the catheter through a small incision in a vein in the groin and guides it to the heart. The catheters tip is positioned at various locations within the heart, where the doctor uses a generator to deliver RF energy. The system comprises a delivery catheter and a self-expanding metal stent made of nitinol.
A porous membrane was engineered to capture RNA on its surface. A CRISPR-based reaction generates a fluorescent signal in the presence of SARS-CoV-2 viral RNA in a saliva sample. When these probes are cut along with the target sequence, a fluorescent signal is produced, indicating that the target has been successfully cut.
It’s likely no coincidence that Pfizer’s flagship project in 2020 while the design of the logo was being finalised was unquestionably its high-profile alliance with BioNTech on the RNA-based coronavirus vaccine Comirnaty, which provided further evidence of the potential of harnessing genetic toolkits to tackle health issues.
Thalassaemia is a severe genetic disease that is characterised by significantly reduced production of functional beta-globin, a component of haemoglobin, the oxygen-carrying protein in the blood. Severely-affected patients need regular blood transfusions to maintain their haemoglobin levels.
Their technology is based on synthetic messenger RNA – short for ribose nucleic acid – which is a short transcript of a longer DNA code. As it’s just a messenger molecule, it does not affect the body’s own genetic code when it is injected as a vaccine – but what it does do is instruct cells to code for copies of a certain protein.
The antiviral agent incorporates RNA-like building blocks into the RNA genome of the virus. If this genetic material is further replicated, defective RNA copies are produced and the pathogen can no longer spread. When it enters the cell, it is converted into RNA-like building blocks.
XTALKS WEBINAR: Using CRISPR interference (CRISPRi) Viability Screens to Map Long Noncoding RNA Dependencies in Tumor Cells. Register for this webinar to get an overview of the role of long non-protein coding RNAs (lncRNAs) in gene regulations. Live and On-Demand: Thursday, April 21, 2022, at 11am EDT (4pm BST/UK).
To understand how quickly the industry responded, one need only look at the development history of Moderna’s COVID-19 vaccine: the company took all of two days to transition from receiving the genetic sequence of the virus to creating a vaccine candidate.
The FDA has approved Alnylam’s gene silencing drug Oxlumo, the first treatment for primary hyperoxaluria type 1 (PH1), an ultra-rare and life-threatening genetic disorder. Oxlumo (lumasiran) was also approved in the European Union last week, making it the third from Alnylam’s pipeline of RNA interference therapeutics to make it to market.
Still, when doctors told her last year that the cancer was growing despite two operations, radiation therapy, and a fifth regimen of chemotherapy, the retired business-meeting facilitator decided to do something unorthodox: spend $83,000 out of pocket on an unproven experimental cancer vaccine.
Currently, after surgery, doctors examine a specimen of a tumor under a microscope and grade it one, two or three in its aggressiveness. The paper was published today in Nature Genetics. “Eventually we hope to tailor medical therapy to the genetic changes within each individual person’s meningioma,” Magill said.
Lab tests that look for the coronavirus’s genetic material using a technique called polymerase chain reaction (PCR) are still considered the gold standard for detecting the virus. Like PCR, the new test repeatedly copies genetic material until it reaches detectable levels. But the new at-home test relies on similar principles.
. “By applying high-resolution imaging, advanced cell and molecular readouts and RNA sequencing methods leveraging the OTME-Chip, we discovered the actual genetic signaling pathways behind the blood cell triggered metastasis of ovarian cancer and a new drug strategy to stop this process.”
Both companies used a synthetic version of coronavirus genetic material called messenger RNA to program a person’s cells to churn out copies of a fragment of the virus, the Times said. Doctors say this reflects India’s younger and leaner population.
The vaccine uses a technology never before used: Each injection contains lipid nanoparticles — fat bubbles — that surround a strip of genetic material called messenger RNA, the Post reported. The genetic material carries the blueprint for the distinctive spiky protein that protrudes from the virus’ surface.

The company’s candidate vaccine, mRNA-1273, is a synthetic messenger RNA that encodes the stabilized SARS-CoV-2 spike protein. CanSino Biologics is developing a vaccine that involves snipping a bit of the virus’ genetic code off and coupling it with a harmless virus to provoke a SARS-CoV-2 immune response.
