AI Article Synopsis

  • - This study looked at how transmissible spongiform encephalopathies (like mad cow disease) can be transmitted between different species by examining prion proteins.
  • - Researchers focused on how disease-associated prion proteins (PrPd) affect the normal form of prion proteins in humans, considering three key genetic variants.
  • - Results indicated that the shape of PrPd plays a significant role in determining how susceptible different hosts are to these diseases.

Article Abstract

To assess interspecies barriers to transmission of transmissible spongiform encephalopathies, we investigated the ability of disease-associated prion proteins (PrPd) to initiate conversion of the human normal cellular form of prion protein of the 3 major PRNP polymorphic variants in vitro. Protein misfolding cyclic amplification showed that conformation of PrPd partly determines host susceptibility.

Selective inhibition of histone deacetylase 8 (HDAC8) has emerged as a promising approach for treating various diseases, including cancer. However, finding key structural features for HDAC8 inhibition and developing effective and selective HDAC8 inhibitors (HDAC8s) pose significant challenges. In the past few years, the development of various scaffolds for inhibiting HDAC8 has significantly risen and the quest continues.

Proteins are some of the most important components in living organisms. When nanoparticles enter a living system, they swiftly interact with proteins to produce the so-called "protein corona", which depicts the adsorption of proteins on large nanoparticles (normally tens to hundreds of nanometers). However, the sizes of small nanoparticles (typically, fluorescent nanomaterials such as quantum dots, noble metal nanoclusters, carbon dots, ) are less than 10 nm, which are comparable or even much smaller than those of proteins.

Five series of new 1,3,4-thiadiazole hybrids were designed and synthesized as promising EGFR inhibitors. Three human cancer cell lines were employed for testing each hybrid's in vitro antiproliferative efficacy; colon HCT-116, liver HepG-2 and breast MCF-7 using MTT assay. Comparing compound 9a to the reference doxorubicin, 9a shown superior activity to that of Dox with respect to MCF-7 (IC 3.
