Exploring the Anti-Osteoporotic Effects of -Hexane Fraction from Nakai: Activation of Runx2 and Osteoblast Differentiation In Vivo.

Background: Osteoporosis is characterized by the microstructural depletion of bone tissue and decreased bone density, leading to an increased risk of fractures. Nakai, an endemic species of the Korean Peninsula, grows wild in Ulleungdo. In this study, we aimed to investigate the effects of and its components on osteoporosis.

Size-controlled assembly of phase separated protein condensates with interfacial protein cages.

Phase separation of specific proteins into liquid-like condensates is a key mechanism for forming membrane-less organelles, which organize diverse cellular processes in space and time. These protein condensates hold immense potential as biomaterials capable of containing specific sets of biomolecules with high densities and dynamic liquid properties. Despite their appeal, methods to manipulate protein condensate materials remain largely unexplored.

Anticancer Ribosomally Synthesized and Post-Translationally Modified Peptides from Plants: Structures, Therapeutic Potential, and Future Directions.

Cancer remains a significant medical challenge, necessitating the discovery of novel therapeutic agents. Ribosomally synthesized and post-translationally modified peptides (RiPPs) from plants have emerged as a promising source of anticancer compounds, offering unique structural diversity and potent biological activity. This review identifies and discusses cytotoxic RiPPs across various plant families, focusing on their absolute chemical structures and reported cytotoxic activities against cancer cell lines.

Plant cross-fertilization for production of dual-specific antibodies targeting both Ebola virus-like particles and HER2 protein in F plants.

Background: This study explores the cross-fertilization of transgenic tobacco plants to produce dual-specific monoclonal antibodies (mAbs) targeting Ebola virus-like particles and HER2 proteins. We generated F plants by hybridizing individual transgenic lines expressing the anti-HER2 breast cancer VHH mAb (HV) and the H-13F6 human anti-Ebola large single chain mAb (EL).

Objective: Hybridizing transgenic plants to express dual-antibodies between different structures VHH and LSCK indicate the potential of transgenic plants as a cost-effective and scalable production system for dual targeting mAbs.

Genomic and transcriptomic signatures of sequential carcinogenesis from papillary neoplasm to biliary tract cancer.

Background & Aims: Papillary neoplasms of the biliary tree, including intraductal papillary neoplasms (IPN) and intracholecystic papillary neoplasms (ICPN), are recognized as precancerous lesions. However, the genetic characteristics underlying sequential carcinogenesis remain unclear.

Methods: Whole-exome sequencing was performed on 166 neoplasms (33 intrahepatic IPNs, 44 extrahepatic IPNs, and 89 ICPNs), and 41 associated carcinomas.
