Despite the current hype around so called “advanced therapies”, which range from gene editing to cell therapies, and the inexorable advance of biologic therapeutics such as monoclonal antibodies, even in 2022 the majority of drugs in development and reaching patients are still small organic molecules.
The mission of Lineage Cell Therapeutics is to deliver on some of the early promises of cell therapy. Cell therapy as a concept is a wonderful idea, but many of the early efforts never generated the kind of clinical data that gets people excited and leads to new medicines. Hearing aids also have all sorts of deficits.
2 Unmet needs in lung cancer treatment Recent decades have seen significant advancements in lung cancer treatment, especially with the introduction of targeted therapies and immunotherapies, which have notably improved survival rates. These can include anti-tubulin compounds, potentially reducing side effects and improving quality of life.
These multifunctional smallmolecules are like tiny spies, hijacking the body’s natural protein degradation system to remove unwanted proteins. For example, PROTACs targeting STAT3, a protein crucial for tumor growth, have shown promise where conventional therapies have failed.
2 In response, DNA-damaging agents that could target the entire cell cycle received renewed attention as ADC payloads. Groundbreaking strategies like proteolysis-targeting chimeric molecules (PROTACs) are also being explored. 4 But the horizon of ADCs is expanding even further, with the design of complex payloads.
One approach is to look beyond the traditional drug molecule. Researchers are experimenting with biologics—larger biological molecules that can do things smallmolecules can't, like targeting larger, more complex structures on cell surfaces or even inside cells.
2 It is this complexity that necessitates powerful, targeted combination therapies. 4, 5 More recently, new combination regimens have emerged that incorporate targeted therapies to treat a variety of blood cancers, including multiple myeloma (MM), chronic lymphocytic leukaemia (CLL) and acute myelogenous leukaemia (AML).
Rare Roundup KRIBB develops new gene therapy candidate for hereditary spastic paraplegia This week we’re flipping the format and starting with our Rare Roundup, after families contacted us with this article about a gene therapy candidate for hereditary spastic paraplegia.
Instead of the black, printed stripes of the Universal Product Codes (UPCs) that we see on everything from package deliveries to clothing tags, they used short, unique snippets of DNA to label cells. DNA barcoding has already empowered single-cell analysis, including for nerve cells in the brain. PRISM consists of two key components.
Gleevec is a smallmolecule that interferes with entry of an enzyme – a tyrosine kinase – that enables growth signals to enter specific cells and trigger division. A name ending in “nib” means a smallmolecule that inhibits an enzyme called a kinase, and is short for “inhibit.”
And unlike traditional DNA sequencers, which parse genetic material by breaking it up into fragments and interpreting it chunk-by-chunk, a nanopore device unspools a long strand of DNA and reads it all at once. A scientist can isolate DNA and load up a flow cell in fifteen minutes. Nanopore devices work incredibly fast.
By harnessing the vast amounts of data generated throughout the development pipeline, pharmaceutical companies can accelerate the discovery of novel therapies, optimize clinical trial design, enhance drug safety monitoring, and deliver personalized medicine, ultimately improving patient outcomes and transforming the future of healthcare.
Acquired cysteines are both driver mutations and sites targeted by precision therapies. For both cancer and healthy genomes, we find that cysteine acquisition is a ubiquitous consequence of genetic variation that is further elevated in the context of decreased DNA repair.
Broadens company’s oncology platform of Targeted Alpha Therapies / Acquisition includes actinium-225 labeled differentiated PSMA smallmolecule for the treatment of prostate cancer. It has been demonstrated to inflict difficult to repair damage to tumor cells by inducing DNA double strand breaks.
We believe liquid biopsy is very helpful for oncology drug development because the reduction and clearance of circulating DNA occurs quickly before radiographic imaging is available. The initial techniques were able to detect circulating tumour DNA in patients who already had metastatic spread.
As soon as I learned about DNA and RNA, I wanted to be a molecular biologist. Last stops at RNA My last roles in biotech were where my original passion began: DNA and RNA. My last stop at Arrakis Therapeutics is with a company targeting RNA with smallmolecules. I wanted to use molecular biology to create drugs.
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. Read Switchable hydrophobic pockets in DNA protocells enhance chemical conversion. Nature Microbiology. Meeussen J.V.W.
Through the acquisition, Gilead gains rights to a portfolio of smallmolecule inhibitors targeting PARP1 for oncology and MK2 for inflammatory diseases that could enter clinical trials later this year. Executive Vice President, Research, Gilead Sciences. The company was founded in 2021 by Stephen Kaldor, Ph.D., Qing Dong, Ph.D.,
Signal Transduction and Targeted Therapy. Marine biofilm engineered to produce current in response to smallmolecules. Digital nanoreactors to control absolute stoichiometry and spatiotemporal behavior of DNA receptors within lipid bilayers. CRISPR-induced DNA reorganization for multiplexed nucleic acid detection.
These hair clip-like molecules clamp onto DNA, thereby turning many genes on and off. Darnell’s 2002 paper Transcription Factors as Targets for Cancer Therapy , in which he wrote: “A limited list of transcription factors are overactive in most human cancer cells, which makes them targets for the development of anticancer drugs.
Most cells (excluding T-cells and B cells after V(D)J recombination) in our body contain the same DNA but appear and behave in distinct ways: A neuron looks and acts very differently from a hepatocyte. While DNA is relatively stable , the epigenome is not; it has to orchestrate changes in cell state, cell type, and more.
.
The current standard of care for GBM consists of de-bulking surgery followed by combined treatments with fractionated ionizing radiation (IR) and the DNA alkylating agent temozolomide (TMZ). At the stage of GBM relapse and recurrence, no effective therapy strategies currently exist.

Augustin et al summarized how novel platforms have more recently been applied to try to solve this question including CRISPR genome editing combined with adoptive cell therapy, siRNA knockdown, DNA encoded library approaches and machine learning algorithms.
The company’s novel first-in-class AKR1C3 targeted therapy is OBI-3424 (small-molecule prodrug) that selectively releases a potent DNA alkylating agent in the presence of the aldo-keto reductase 1C3 (AKR1C3) enzyme. Additional information can be found at www.obipharma.com.
This week: A way to measure a transgene’s expression in the brain using ultrasound, a DNA sequencing method that uses 1000x less reagents, and base editors get even smaller. An engineered version of this protein can convert DNA bases with efficiencies up to 92%. so this Digest will be published more irregularly.

The new technique controls gene activity without altering the DNA sequence of the genome by targeting chemical modifications that help package genes in our chromosomes and regulate their activity. In this experiment, however, the cutting function of the Cas9 protein is disabled so the genomic DNA sequence is unaltered.
Psychedelics Psychedelic therapy (or psychedelic-assisted therapy) refers to the use of psychedelic drugs, such as psilocybin, MDMA, LSD, ketamine, and ayahuasca, to treat mental disorders, especially those that have no effective treatments available or are treatment resistant.
By manipulating the microbes’ DNA, they programmed gene circuits that control the bacteria surface, building a molecular “cloak” that encapsulates the bacteria. They control the iCAP system by giving it an external cue – a smallmolecule called IPTG – that allows for programmable and dynamic alteration of the E.
Yeast die for two reasons: Either their nucleolus (where the DNA is kept) degrades and dies, or their mitochondria whimpers out and they stop making energy. The vaccine printer can make lots of different types of vaccines, including protein, DNA, and mRNA ones, but I’m sure this is all quite expensive right now. From Zhang et al.

Dr. Kaur now oversees 5 KAND research projects that utilize our patient-derived cell lines to screen for smallmolecule therapeutics and test potential gene therapies. This would allow a single gene therapy to replace an area of KIF1A that includes multiple disease-causing mutations, and treat multiple mutations at once.
Then, he identified the problem: “Really, what the tumor has done is to figure out a way to hide from the immune system, and all of our therapy has actually been helping that tumor to hide from the immune system. The last year, I think, is a very exciting year for cell therapy against cancer. NK Cells Locked, Loaded, and Ready to Fire.
NYSE American and TASE: LCTX), a clinical-stage biotechnology company developing allogeneic cell therapies for unmet medical needs, today provided a year-end review and an outline of its plans for 2021. CARLSBAD, Calif.–( –( BUSINESS WIRE )– Lineage Cell Therapeutics, Inc.
Susannah is being treated with an Antisense Oligonucleotide (ASO) : To break down the term, this is a molecule designed with a sequence of 20 (oligo, “few”) letters of DNA (nucleotide) that match a sequence on the mutant KIF1A RNA (Antisense) and knock it down. Will this _ KAND?
Patients frequently receive up to four therapies at once and go through multiple prolonged courses of treatment to keep recurrence and progression at bay. Commonly combined treatment options include antineoplastics (chemotherapies), radiation therapy, corticosteroids, immunomodulators, proteasome inhibitors, and monoclonal antibodies.
