Emerging role of A-kinase anchoring protein 5 signaling in reward circuit function

Neural Regeneration Research 2025年第10期20卷 2913-2914页

There is a strong evidence supporting the hypothesis of synaptic dysfunction as a major contributor to neural circuit and network disruption underlying emotional and mood dysregulation in psychiatric disorders(Simmons et al.,2024).Diverse sets of distinct molecular signaling pathways converge on the synapse to regulate synaptogenesis,synaptic function,and synaptic plasticity in brain regions and circuits through complex interactions organized by numerous multivalent protein scaffolds,including the family of proteins known as A-kinase anchoring proteins(AKAPs).

Cystatin C Peptide Effects on B16F10 Melanoma Cells

引用

CellBio 2021年第1期10卷 1-9页

作者： Mathieu Hill James l. cox AT Still University Department of Biochemistry West Jefferson Kirksville Missouri USA

Background: Metastasis is a major problem for effective therapy of cancer. Small cysteine protease inhibitors, cystatins have been shown to be anti-metastatic for a number of different cancers. We have identified a small peptide of cystatin which exhibits anti-cancer properties for B16 melanoma cells in vitro. Methods: B16 melanoma cells were measured for growth, proliferation, migration, and apoptosis in the presence and absence of cystatin peptide. Results: The cystatin peptide reduced melanoma cell growth, proliferation, migration, and increased apoptosis in melanoma cells in culture. Conclusion: Cystatin peptide exhibits anti-cancer effects on highly metastatic B16 melanoma cells in culture.
