Lgr5: From Stem Cell Marker To Therapeutic Target, Peyton C High, Maya G Cappellino, Tiffani A Blackburn, Kendra S Carmon

Faculty, Staff and Student Publications

Leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5) is an established marker of normal and cancer stemlike cells. LGR5 has been implicated in promoting cancer cell plasticity that drives tumorigenesis, metastasis, and therapeutic resistance. LGR5 rapidly and constitutively internalizes and potentiates Wnt (Wingless/Int-1)/β-catenin and adhesion signaling pathways, though its precise mechanisms and interacting partners remain unresolved. An improved understanding of LGR5 signaling may provide invaluable insight into its intricate and important functions in cancer progression. Moreover, several LGR5-targeting therapies, including peptibody- and antibody-drug conjugates and bispecific antibodies, are showing promising efficacy and tolerability in colorectal cancer and other tumor types.

Mitochondrial Presequences Harbor Variable Strengths To Maintain Organellar Function, Youmian Yan, Baigalmaa Erdenepurev, Thiago N Menezes, Ian Collinson, Natalie M Niemi

2020-Current year OA Pubs

Hundreds of mitochondrial proteins rely on N-terminal presequences for organellar targeting and import. While generally described as positively charged amphiphilic helices, presequences lack a consensus motif and thus likely promote protein import into mitochondria with variable efficiencies. Indeed, the concept of presequence strength underlies biological models such as stress sensing, yet a quantitative analysis of what dictates strong versus weak presequences is lacking. Furthermore, the extent to which presequence strength affects mitochondrial function and cellular fitness remains unclear. Here, we capitalize on the MitoLuc protein import assay to define multiple aspects of presequence strength. We find that select presequences, including …

The Thai Journal of Veterinary Medicine

A 10-year-old female Pomeranian was referred after a hepatic cyst was incidentally identified during a routine health check. Ultrasound-guided simple drainage was initially performed, and cytological examination of the aspirated fluid confirmed a simple cyst. However, the cyst re-expanded to its original size within 2 weeks. Therefore, ultrasound-guided percutaneous sclerotherapy was elected using lower-concentration ethanol (83%), a readily available medical disinfectant, rather than conventional high-concentration ethanol. Approximately 50% of the aspirated volume was replaced with 83% ethanol and retained for 20 min to achieve effective epithelial ablation. Post-procedural follow-up revealed a transient increase in cyst size and serum alanine aminotransferase …
