Distribution of mitochondrial chaperonins in lung cells

Hsp10 nuclear localization and changes in lung cells response to cigarette smoke suggest novel roles for this chaperonin
2014
Heat-shock protein (Hsp)10 is the co-chaperone for Hsp60 inside mitochondria, but it also resides outside the organelle. Variations in its levels and intracellular distribution have been documented in pathological conditions, e.g. cancer and chronic obstructive pulmonary disease (COPD). Here, we show that Hsp10 in COPD undergoes changes at the molecular and subcellular levels in bronchial cells from human specimens and derived cell lines, intact or subjected to stress induced by cigarette smoke extract (CSE). Noteworthy findings are: (i) Hsp10 occurred in nuclei of epithelial and lamina propria cells of bronchial mucosa from non-smokers and smokers; (ii) human bronchial epithelial (16HBE) a…

Focusing on a quantification and characterization of extracellular vesicles from blood in brain tumors
Molecular chaperones are required to maintain the proteome in a folded and functional state. Chaperones are structurally and functionally normal but participate in pathways that favor disease, as a tumorigenesis (1). The incidence of brain tumors is increasing rapidly and surgery is the first therapeutic intervention to safeguard the patient's life. The prognosis is poor even after surgical resection, followed by post-operatory chemo- and radio-therapy (2). Tumor-secreted extracellular vesicles (EVs) are critical mediators of intercellular communication between tumor cells and stromal cells in local and distant microenvironments. EVs play an essential role in both primary tumor growth and m…
