Amphiphilic bile acids linked through an oligoethylene glycol to a biotin moiety were synthesized and shown to create micellar structures in aqueous environment, interact with avidin and be efficiently incorporated into hepatocyte cells, suggesting their potential as a drug delivery system against liver diseases.

Interleukin 1 beta (IL-1β) and IL-1 receptor antagonist (IL-1RA) are both upregulated following traumatic injury. As IL-1RA blocks inflammatory signaling by IL-1β, overexpression of IL-1β relative to IL-1RA may drive inflammatory diseases. As such, determination of the relationship between IL-1β to IL-1RA expression levels in horses may provide insight into disease states or serve as a therapeutic readout of response to medical interventions.

Most tumors initially respond to treatment, yet refractory clones subsequently develop owing to resistance mechanisms associated with cancer cell plasticity and heterogeneity. We used a chemical biology approach to identify protein targets in cancer cells exhibiting diverse driver mutations and representing models of tumor lineage plasticity and therapy resistance. An unbiased screen of a drug library was performed against cancer cells followed by synthesis of chemical analogs of the most effective drug.

Background/objectives: The enzyme ubiquitin-specific protease 44 (USP44) is a deubiquitinating enzyme with identified physiological roles as a tumor suppressor and an oncogene. While some binding partners and substrates are known for USP44, the identification of other interactions may improve our understanding of its role in cancer. We therefore performed a proximity biotinylation study that identified products of several known cancer genes that are associated with USP44, including a novel interaction between BRCA2 and USP44.

Introduction: Brugada Syndrome (BrS) is an inherited arrhythmia syndrome characterised by ST-segment elevation in the right precordial ECG leads and is associated with an increased risk of sudden cardiac death. We identify and characterise a novel SCN3B variant encoding the regulatory β3-subunit of the cardiac voltage-gated sodium channel, Na1.5.

A critical challenge in boron neutron capture therapy (BNCT) is expanding its effectiveness through the development of novel boron agents with different mechanisms of action than the approved drug 4-borono-l-phenylalanine (BPA). In this study, we developed a small molecule boron carrier, biotinyl--dodecaborate conjugate with an iodophenyl moiety (BBC-IP), incorporating biotin as a ligand for biotin receptors overexpressed in various cancer cells, alongside an albumin ligand and boron source. BBC-IP exhibited high water solubility, minimal cytotoxicity, and superior cellular uptake compared to BPA in both human and mouse cancer cells.
