Cystatins in cancer progression: More than just cathepsin inhibitors
The cystatins are a family of cysteine protease inhibitors which share a sequence homology and a common tertiary structure of an alpha helix lying on top of an anti-parallel beta sheet. The family is subdivided as described below. Cystatins show similarity to fetuins, kininogens, histidine-rich glycoproteins and cystatin-related proteins. Cystatins mainly inhibit peptidase enzymes (another t… WebJun 13, 2024 · Cystatin SN in nasal secretion was measured using a commercially available enzyme-linked immunosorbent assay (ELISA) kit (Cloud-Clone Corp, Wuhan, China).

WebThus cystatin SN inhibits replication of herpes simplex virus-1 (Gu et al., 1995; Weaver-Hiltke and Bobek, 1998), but not as effectively as cystatin C, and cystatin D inhibits replication of coronavirus (Collins and Grubb, 1998). Many types of cystatins have a wide range of effects on immune cells (reviewed by Dickinson, 2002). WebNov 1, 2024 · During cancer progression, cystatin SN affects cell senescence. Cystatin SN knockdown and reduced extracellular cathepsin B activity induces the inhibitory phosphorylation of glycogen synthase kinase 3β (GSK3β) that results in increased glycogen accumulation and cell senescence [ 150 ].
