BACKGROUND It is increasingly clear that some heat shock proteins (Hsps) play a role in inflammation. Here, we report results showing participation of Hsp60 in the pathogenesis of chronic obstructive pulmonary diseases (COPD), as indicated by data from both in vivo and in vitro analyses. METHODS AND RESULTS Bronchial biopsies from patients with stable COPD, smoker controls with normal lung fu...
Bisphenol S (BPS) is an industrial alternative to the endocrine disruptor bisphenol A (BPA), and can be found in many products labeled "BPA-free". Its use has grown in recent years, and presently it is considered a ubiquitous emerging pollutant. To date there is a lack of information on the effects of BPS on invertebrates, although they represent more than 95% of known species in the animal kin...
Diffusion coefficients of huntingtin (Htt) fragments and SOD1 mutants expressed in cells were measured using fluorescence correlation spectroscopy. The diffusion mobilities of both non-pathological Htt fragments (25 polyQs) and pathological Htt fragments (103 polyQs) were much slower than expected for monomers suggesting that they oligomerize. The mobility of these fragments was unaffected by d...
Background: ERdj4 is an endoplasmic reticulum chaperone co-factor that assists with destruction of misfolded secretory proteins. Results: ERdj4 is amobile soluble luminal protein that is recruited to themisfolded secretory protein quality controlmachinery. Conclusion: The role of ERdj4 in secretory protein destruction is specified by association with the degradation machinery. Significance: The...
It is well established that chaperones modulate the protein folding free-energy landscape. However, the molecular determinants underlying chaperone-mediated mechanical folding remain largely elusive, primarily because the force-extended unfolded conformation fundamentally differs from that characterized in biochemistry experiments. We use single-molecule force-clamp spectroscopy, combined with ...
In light of increasing sea surface temperatures, quantifying the expression of stressinducible genes in coastal organisms is imperative to identify early biomarkers of thermal stress. In the present study we developed a quantitative PCR (qPCR) assay to test the molecular response to heat stress in the Great Barrier Reef sponge Rhopaloeides odorabile. Suitable reference genes (coding for α-tubul...
Parkinson's disease (PD) is a common neurodegenerative disease characterized by the loss of dopaminergic neurons in the substantia nigra and the aggregation of α-synuclein into Lewy bodies. Existing therapies address motor dysfunction but do not halt progression of the disease. A still unresolved question is the biochemical pathway that modulates the outcome of protein misfolding and aggregatio...
Loss-of-function mutations in the KCNQ4 channel cause DFNA2, a subtype of autosomal dominant non-syndromic deafness that is characterized by progressive sensorineural hearing loss. Previous studies have demonstrated that the majority of the pathogenic KCNQ4 mutations lead to trafficking deficiency and loss of KCNQ4 currents. Over the last two decades, various strategies have been developed to r...
