Using interactions between viral peptides and human proteins as a starting point, researchers from Enyo Pharma Inc., the University of Lyon and other institutions were able to bootstrap themselves to a mitochondria-targeting small molecule that showed activity in a mouse model of nonalcoholic steatohepatitis (NASH) with chronic kidney disease.
The field of peptides is exploding, Perpetual Medicines Corp. co-founder, chairman and CEO Kerry L. Blanchard recently told BioWorld, “with a projected growth rate far surpassing large and small molecules, and gene therapies. The area is underinvested, too, so this is a good opportunity to focus on peptide therapeutics.”
If we unraveled the DNA of the 46 chromosomes of a single human cell, it would barely measure 2 meters. If we did the same with the rest of the body, if we aligned the 3 billion base pairs of its 5 trillion cells, we could travel the distance from the Earth to the Sun more than 100 times. It seems unreachable. However, that is the unit of knowledge of the large sequencing projects achieved in 2023. From the generation of the human pangenome to cell-by-cell maps of the brain and kidneys, scientists this year have completed several omics collaborative projects stored in large international databases. Now, what’s the plan?
Modifying a patient’s DNA is no longer just for science fiction novels. The CRISPR gene editing technique developed by Jennifer Doudna and Emmanuelle Charpentier only took 10 years to reach the market as Casgevy (exagamglogene autotemcel/exa-cel, Vertex Pharmaceuticals Inc.), treating congenital pathologies such as β-thalassemia and severe sickle cell disease. But science does not stop.
Artificial Intelligence (AI) driven tools have the ability to design new drugs, with a bit of help from humans, said Anders Hogner, from Astrazeneca plc’s R&D department at the Bio-IT World Conference & Expo Europe in London. “We don’t have anything out there yet,” he added, but the company appears to be working on it.
Investigators at the Chinese Academy of Sciences have generated a chimeric monkey by injecting an embryonic stem cell into the morula, which is an extremely early embryo consisting of 16 to 32 cells. The animal survived for only 10 days, and it is not the first live birth of a chimeric primate. But it is the first such chimera with contributions from an embryonic stem cell, and that stem cell contributed a far higher proportion of cells in the newborn than have been achieved in previous attempts at creating chimeras.
At the 30th Annual Congress of the European Society for Gene and Cell Therapy in Brussels this week, researchers presented both preclinical and clinical strategies for applying gene therapy to a functional HIV cure. At a Wednesday session on Infectious Diseases & Vaccines, Alessio Nahmad, of Tabby Therapeutics Ltd., described using B cells edited to express broadly neutralizing antibodies (bnAbs) 3BNC117 to deliver high titers of antibodies in mice.
Fledgling biotechnology company Automera has launched in Singapore with $16 million in series A funding to develop its autophagy-targeting chimera small molecules (AUTACs) platform technology. Automera co-founder and chief technology officer Loong Wang told BioWorld that he and his business partner, Taiyang Zhang, decided to move into the biotechnology space in 2021.
Some cancers with a poor prognosis have had no new treatments in decades. Advances in the genetic characterization of these tumors now offer a range of possibilities for the development of new therapies that could completely change the quality of life and survival of these patients.
Quantum dots, a phenomenon in quantum physics that alters the energy of electrons and changes the properties of particles, caught the attention of the Royal Swedish Academy of Sciences (KVA) for the 2023 Nobel Prize in Chemistry. Alexei Ekimov and Louis Brus received the award for their discovery; Moungi Bawendi, for developing its applications. With their work, “in equal shares,” said the Secretary General of KVA Hans Ellegren, the three scientists have laid the foundations of nanotechnology, a tool that we see today in our homes, on televisions and LED lamps, or in laboratories and hospitals for designing new drugs or new strategies against cancer.
