Findings from a study, which was conducted by Transcenta and Shanghai Jiao Tong University scientists on TST003 to treat androgen receptor-negative/low prostate cancer, were published by Nature Cancer in May last year. The Gremlin1 protein was found to promote lineage plasticity while driving castration resistance in prostate cancer.
With the rapid development of biotechnology and molecular medicine, the introduction of mRNA as a vaccine or therapeutic agent enables the production of almost any desired functional protein/peptide within the human body.
Antibody-like proteins that capture and neutralize SARS-CoV-2 Scientists have used a new high-speed, in vitro selection method to isolate 9 antibody-like proteins (ALPs) that bind to the SARS-CoV-2 virus – 4 of which also exhibited neutralizing activity – within 4 days, according to a new study.
According to the US biopharma company, genetic analyses of publicly available sequences for the new variants of SARS-CoV-2 suggest the mutations in the viral spike protein that have made them more transmissible shouldn’t affect the way Veklury (remdesivir) works. The UK strain – known as B.1.1.7
Now, thanks to a study funded by the National Institutes of Health Intramural Research Program, scientists have discovered that ?-synuclein, synuclein, a protein involved in the formation of amyloid deposits in the brain characteristic of Parkinson’s disease and other neurodegenerative disorders, is also implicated in melanoma.
One nanobody in particular, called NIH-CoVnb-112, was shown to be able to prevent COVID-19 infection from the novel coronavirus by targeting both the spike protein on SARS-CoV-2, as well as the angiotensin converting enzyme 2 (ACE2) receptor that it binds to on human cells.

For decades, formulation scientists have relied on the assumption that common pharmaceutical excipients are biologically inert. For example, Advil tablets contain 18 inactive ingredients alongside ibuprofen, the drug’s active pharmaceutical ingredient (API). But just how inert are these excipients?
Even as several safe and effective COVID-19 vaccines are being administered to people worldwide, scientists are still hard at work developing different vaccine strategies that could provide even stronger or longer-lasting immunity against SARS-CoV-2 and its variants. bioRxiv [Preprint]. 2021 Apr 8:2021.04.08.438884.

Exploring the implementation of complex in-vitro models for drug development. The pharmaceutical industry globally is realising the growing potential of in vitro tissue models for drug discovery, pathology modelling and validation, safety and toxicity. Etienne De Braekeleer, Senior Research Scientist, AstraZeneca.
COVID-19 antigen tests diagnose active infection by detecting SARS-CoV-2 viral proteins in samples, as opposed to PCR tests which detect viral RNA and require lab processing, but can miss infections with low virus levels. The test – which can also be self-collected – showed a sensitivity of 93.8%
Both the areas of drug development and clinical trials are increasingly using in vitro assays to help determine the efficacy of an investigational therapeutic. Flow cytometric receptor occupancy assays are being increasingly used in preclinical and clinical studies. What is Flow Cytometry?
Scientists at the University of Cambridge evaluated the use of a personalized blood test that detects ctDNA to help predict the relapse risk of lung cancer. Register for this webinar to get an overview of the role of long non-protein coding RNAs (lncRNAs) in gene regulations. Photo source: Inivata.
Developing Complex, Translatable and Physiologically-Relevant Cellular Models in vitro. Key Benefits of Attending: • Discuss the uses of advanced cell technologies to construct in vitro models of human tissues. Academia Professor – Cell Technology, Stem Cell Sciences, Biochemistry, Protein Technology and Tissue Engineering.
Several FDA-approved drugs – including for type 2 diabetes, hepatitis C and HIV – significantly reduce the ability of the Delta variant of SARS-CoV-2 to replicate in human cells, according to new research led by scientists at Penn State. ” The findings published today (Feb. 25) in the journal Communications Biology. .
With the Omicron variant of SARS-CoV-2 continuing to run rampant, Italian in vitro diagnostics (IVD) company A.Menarini Diagnostics has unveiled a new real-time (RT)-PCR-based test that can detect several variants of the coronavirus including Omicron and Delta. We are extremely proud to have made this unique solution available so quickly.
However, in vitro or binding-based efficacy insight needs to be confirmed by reliable clinical evidence, as shown by the outcomes of COVID-19 trials with remdesivir and hydroxychloroquine. million worldwide and continues to increase despite the global public health measures that have been put in place.
The LumiraDx SARS-CoV-2 Antigen Test uses Fast Microfluidic Immunofluorescence (FMI) technology to detect antigen nucleocapsid protein from nasal or nasopharyngeal swabs with high sensitivity results in 12 minutes. LONDON , Jan. Test specificity was 99.5% in nasal swab specimens. in nasal samples and 97.8% in nasopharyngeal samples.
As a novel virus, public health experts, scientists and clinicians faced challenges in how to effectively prevent its transmission, and how to best treat it in the most severe cases. After its identification in late 2019, COVID-19 was officially declared a pandemic by the World Health Organization (WHO) on March 11, 2020. COVID-19 Treatments.
Klisyri is a home-grown product discovered and characterized by Athenex scientists and developed from pre-IND to NDA by the Athenex team. The data supported the potential benefits of the drug for OAB in patients with urge urinary incontinence (UUI), urgency, and urinary frequency. The drug is a once-daily, beta-3 adrenergic agonist.
The LumiraDx SARS-CoV-2 Antigen Test is authorized for use by FDA under an Emergency Use Authorization (EUA) only for the detection of SARS-CoV-2 nucleocapsid protein. The LumiraDx SARS-CoV-2 Antigen Test is authorized for use by FDA under an Emergency Use Authorization (EUA) only for the detection of SARS-CoV-2 nucleocapsid protein.

This research use only laboratory test can be used to help scientists track mutation prevalence and to assess any potential impact on diagnostics, vaccines and therapeutics, providing crucial insight for healthcare systems in making appropriate measures to combat COVID-19. 1.1.7), South Africa (B.1.351), 1.351), and Brazil (P.1). 1.351 and P.1
REGN-COV2 is Regeneron’s two-antibody combination currently in late-stage clinical trials for the treatment and prevention of COVID-19 infection. The companies will collaborate on developing and manufacturing REGN-COV2. Regeneron will distribute REGN-COV2 in the U.S. and Roche will be responsible for distribution outside the U.S. Schleifer, M.D.,
Bacteria plays a crucial role in maintaining the ecosystem balance. However, there are few species of bacteria that can cause several infectious diseases ( such as strep throat, salmonellosis, tuberculosis, whooping cough ). These are mainly transmitted through air, water, living organisms, and food.
It looked like a hurricane had pummeled through my closet…. Wrinkled jeans and dresses scattered in every direction…. There wasn’t a single outfit that fit me…. I swear — I went to bed a size 10 and woke up a size 16. My teenage daughter shouted at me from downstairs for the third time…. I have to be at school in 5 minutes!”. What are you doing?!
Our chemists and formulation scientists review the properties of new drug candidates and “work their magic” to develop formulations that improve the exposure profile of the compound. Quotient Sciences helps biotech and pharma customers in the development and optimization of drug products.
A new type of test based on detection of activated T cells may prove to have greater utility in determining whether someone has had a COVID-19 infection compared to a traditional antibody test. The cell-based tests are designed to identify specific T cells that are activated in response to a pathogen — which in this case would be SARS-CoV-2.
The company’s candidate vaccine, mRNA-1273, is a synthetic messenger RNA that encodes the stabilized SARS-CoV-2 spike protein. The University of Oxford/AstraZeneca partnership, in turn, is testing a viral-vectored coronavirus vaccine that again expresses the spike protein of SARS-CoV-2 virus. The price of that prize is incalculable.
