Cancer treatments for targeting tumor amplifications lag behind those targeting point mutations – and part of the reason may be that amplifications often reside on extrachromosomal DNA (ecDNA). Since ecDNA was first described back in 1965 as minute chromatin bodies in brain cancer cells, the use of large-scale DNA sequencing techniques has revealed the presence of ecDNA across a wide range of cancer types. “The circular structure of ecDNA is associated with increased proto-oncogenic capacity in comparison to linear amplifications. Another key feature is that ecDNA does not contain centromeres,” Roel Verhaak, from Yale School of Medicine, told the audience in a session at the 2023 AACR-NCI-EORTC Conference on Molecular Targets and Cancer Therapeutics in Boston.

Drug discovery in Japan has been steadily declining, and it has reached a crisis point where swift action is needed or pharma companies will leave Japan or stop listing products here, said speakers at the BioJapan 2023 meeting held Oct. 10 to 13 in Yokohama, Japan.

Precision cancer biotech Abion Inc. announced a positive interim phase II readout for ABN-401, its novel c-mesenchymal-epithelial transition (c-MET)-targeting tyrosine kinase inhibitor (TKI) for advanced non-small-cell lung cancer (NSCLC), lighting a runway to its next trial as a combination regimen.

Insanity has often been defined as doing the same thing and expecting different results, and Japan seems to be trapped in that rut largely because it can’t seem to do innovation differently, said speakers at the BioJapan 2023 meeting held Oct. 11 in Yokohama, Japan.

For most psychiatric illnesses, the precipitating event is mysterious. Many conditions are thought to result from a mix of genetic risk and environmental factors, but the specific trigger remains unknown. In post-traumatic stress disorder (PTSD), the environmental trigger is usually clear. In many cases, it is all the affected individuals can think about. “Intrusive reliving” of the triggering situation is one of the core features of PTSD.

In July 2023, South Korea’s Ministry of Trade, Industry and Energy ramped up efforts to kickstart the so-called “Bio Economy 2.0,” the newfound initiative that banks on the biopharmaceutical industry to potentially revitalize the country’s slowing economic and social growth. Highlighting four major areas – biopharmaceuticals, biomaterials, bioenergy and digital technologies – as the four “wheels” to carry the biopharma industry, the new plan underscored the government’s unwavering support for the sector while highlighting its vision to become the “number one bioeconomy” worldwide.
