To the best of my knowledge, labs are working on this in the US, various European countries, China, and elsewhere. Research is a highly international and collaborative profession, and US policies are affecting worldwide research and researchers. That said, I am not an expert on this topic.

Yes! Phage therapy shows promise as a cancer treatment due to its ability to target cancer cells, deliver therapeutic agents, and potentially stimulate antitumor immunity. However, it is still under research in order to prove efficacy and safety.

Let’s explain the “classic” allergy (Type I) using #allergy to cats as an example! 🐱 There are different types of allergies, and symptoms can differ. Many complex factors determine if and when you develop an allergy, and much is still unknown 👀 #SciArt #SciComm #Science #DigitalArt #Animation

Apoptosis is a controlled cell death process essential for development, immunity, and balance. It forms apoptotic bodies cleared by phagocytes, preventing inflammation.

𝘟𝘦𝘯𝘰𝑝𝘶𝘴 𝘭𝘢𝘦𝘷𝘪𝘴 was once used as a #pregnancy test ("Hogben test"), where injecting a woman's urine into the frog could induce egg laying if she was pregnant!🤰 Additionally, females are significantly larger than males, often twice the size 👀.

Due to its high egg production and easy in vitro and in vivo fertilization, it has been widely used for studying #embryogenesis, #organogenesis, #toxicology, and human disease mechanisms. Its embryos are cost-effective, easy to handle, and ideal for studying molecular and mechanical alterations.

CRG researchers have merged genomic and structural data to tackle saturation, the main obstacle for the reconstruction of ancient relationships. Crucially, the approach works even with the predicted structures of proteins that have never been experimentally determined. 📷@queralttolosa.bsky.social

Epitranscriptomic rRNA fingerprinting reveals tissue-of-origin and tumor-specific signatures dlvr.it/TH8ZJY

Epitranscriptomic rRNA fingerprinting reveals tissue-of-origin and tumor-specific signatures

Milenkovic et al. demonstrate that rRNA modifications are differentially modified across tissues, developmental stages, and in disease. The authors show that rRNA modification patterns, also termed “epitranscriptomic rRNA fingerprints,” are sufficient to accurately identify tissue of origin and tumorigenicity, from as few as 250 reads.

Using nanopore sequencing, a team led by @evamarianovoa.bsky.social has discovered different cancers have unique molecular ‘fingerprints’. The findings set the foundation for creating new, non-invasive diagnostic tests that detect the disease faster and earlier than currently possible.
