Design multi state and functional proteins using sequence space diffusion model

Protein Denoising Diffusion Probabilistic Models (DDPM) can efficiently generate novel proteins that meet specific properties and functional requirements, and have significant value in the field of protein design. Although many current models, such as RFdiffusion and Chroma, have shown excellent performance in generating protein three-dimensional structures, there are still challenges in generating proteins with sequence specificity and functional properties, and these models often require a lot of time and computational resources for training. David Baker’s team at the University of Washington has proposed a new solution to address this challenge. They believe that diffusion in sequence space can more effectively learn more knowledge from the current large amount of protein sequence data. Therefore, the research team developed a sequence space diffusion model ProteinGenerator based on RoseTTAFold, which can generate protein sequences and structures that meet the required properties. Subsequently, the research team further successfully designed multiple proteins with different functions ...

【EXPERT Q&A】What are medical device quality management system nonconformities?

Drugdu.com expert’s response: Non-conformities in the quality management system for medical devices refer to situations where an activity or its outcome in the quality management system activities related to medical device production, sales, and after-sales service fails to meet established requirements or standards. These requirements or standards typically originate from relevant regulations, standards, contracts, and internal quality management system documents of the enterprise. Non-conformities can manifest in various forms, including but not limited to non-conformities related to documents, products, processes, personnel, environments, records, and data. Specifically, non-conformities in the quality management system for medical devices may involve the following aspects: Document Non-conformity: Quality management system documents do not comply with applicable laws, regulations, standards, or contracts. For instance, there may be no documented corrective action control procedure established, no clear review of nonconformities (including customer complaints), no determination of the causes of nonconformities, no evaluation of measures needed to ensure ...

Another GLP-1 drug king, is it on the way?

Recently, the Q3 financial reports of MNCs have been released one after another, and some are happy and some are sad. When a number of MNCs began to lower their full-year EPS, Amgen’s Q3 financial report earnings gave a high score answer sheet. Among them, Amgen’s total revenue in the third quarter increased by 23%, and its GAAP net earnings per share (EPS) increased by 62% year-on-year, from US$3.22 to US$5.22. What is more imaginative is that with the data catalysis of the new macromolecular weight loss drug AMG133, this macromolecular antibody that goes against the grain and antagonizes GIPR may become Amgen’s next gold mine. According to Amgen’s Q3 2024 financial report, the most significant year-on-year growth is LUMAKRAS (AMG510) – a targeted drug for KRASG12C mutation-positive lung cancer. The sales ceiling of this gene mutation in European and American countries will be much higher than that in Asian ...

NMN can prevent physical decline and poor sleep

Walking speed reflects the vitality of the muscles, bones, nerves and cardiovascular system, so our walking speed can also predict our lifespan. After the age of 65, our walking speed gradually decreases, and eventually our daily life will be affected, greatly reducing our quality of life. Therefore, it is very important to keep muscles, bones, nerves and heart healthy through endurance and resistance training. Exercise may be the best way to prevent slow walking. However, poor sleep quality and low energy levels may prevent many people from sticking with exercise. In addition, poor sleep quality and fatigue may be the cause of low NAD+ levels. Recently, Japanese scientists published a research article titled “Ingestion of β-nicotinamide mononucleotide increased blood NAD levels, maintained walking speed, and improved sleep quality in older adults in a double-blind randomized, placebo-controlled study” in the journal “GeroScience”. The results showed that supplementing NMN can prevent physical ...

$1.4 billion deal highlights the future of Alzheimer’s disease therapy

The development of therapies for Alzheimer’s disease has always caused many developers to feel exhausted, and now AbbVie has also increased its investment in neurodegenerative diseases. AbbVie has agreed to spend $1.4 billion to acquire Aliada Therapeutics, whose main acquisition asset is Aliada’s authorized Alzheimer’s disease candidate drug ALIA-1758 from Johnson&Johnson. Its mechanism of action is still an anti beta amyloid protein (3pE-A β) antibody, but the unique feature of ALIA-1758 is that it can cross the blood-brain barrier, greatly improving the brain’s absorption rate. Aliada started a phase 1 trial among healthy volunteers in May, but AbbVie believes the timing is ripe for acquisition. Previously, AbbVie made the decision to abandon its internal Alzheimer’s disease asset ABBV-916. This anti beta amyloid antibody has no significant difference in safety and efficacy compared to the already marketed monoclonal antibody therapy for Alzheimer’s disease. Therefore, AbbVie decided to terminate the development ...
