Autophagy is a lysosomal degradation pathway that converts macromolecules into substrates for energy production during nutrient-scarce conditions such as those encountered in tumor microenvironments. Constitutive mitochondrial uptake of endoplasmic reticulum (ER) Ca 2+ mediated by inositol triphosphate receptors (IP 3 Rs) maintains cellular bioenergetics, thus suppressing autophagy. We show the ER membrane protein Bax inhibitor-1 (BI-1) promotes autophagy an IP R-dependent manner. By...
Autophagy is an evolutionarily conserved process for catabolizing damaged proteins and organelles in a lysosome-dependent manner. Dysregulation of autophagy may cause various diseases, such as cancer neurodegeneration. However, the relevance to diseases remains controversial because limited availability chemical modulators. Herein, authors developed fluorescence-based assay measuring activity protease, autophagin-1(Atg4B). The employs novel reporter substrate Atg4B composed natural (LC3B)...
Abstract Small molecule inhibitors of Bruton's tyrosine kinase (BTK) have been approved for the treatment multiple B-cell malignancies and are being evaluated autoimmune inflammatory diseases. Various BTK (BTKi) distinct potencies, selectivity profiles, binding modes within ATP-binding site. On basis latter feature, BTKis can be classified into those that occupy back-pocket, H3 pocket, hinge region only. Hypothesizing differing may differential impact on receptor (BCR) signaling pathway, we...
Endoplasmic reticulum (ER) stress occurs when unfolded proteins accumulate in the lumen of organelle, triggering signal transduction events that contribute either to cellular adaptation and recovery or alternatively dysfunction death. ER has been implicated numerous diseases. To identify novel modulators stress, we undertook a siRNA library screen kinome, revealing Interleukin-1 Receptor-Associated Kinase-2 (IRAK2) as contributor protein response (UPR) signaling stress-induced cell Knocking...
Infantile GM1 gangliosidosis is caused by the absence or reduction of lysosomal beta-galactosidase activity. Studies conducted in Brazil have indicated that it one most frequent storage disorders southern part country. To assess incidence this disorder, 390 blood donors were tested for presence two common mutations (1622-1627insG and R59H) GLB1 gene. Another group, consisting 26 patients, polymorphisms (R521C S532G), an attempt to elucidate whether there a founder effect. The frequencies...
We explored the effect of a novel synthetic triterpenoid compound cyano enone methyl boswellates (CEMB) on various prostate cancer and glioma cell lines. CEMB displayed concentration-dependent cytotoxic activity with submicromolar lethal dose 50% (LD(50)) values in 10 tumor lines tested. CEMB-induced cytotoxicity is accompanied by activation downstream effector caspases (caspases 3 7) upstream initiator involved both extrinsic (caspase 8) intrinsic 9) apoptotic pathways. By using short...

GM1 gangliosidosis is an autosomal recessive disorder caused by the deficiency of lysosomal acid hydrolase beta-galactosidase (beta-Gal). It one most frequent storage disorders in Brazil, with estimated frequency 1:17,000. The enzyme secreted and can be captured deficient cells targeted to lysosomes. There no effective treatment for gangliosidosis. To determine efficiency expression vector correcting genetic defect gangliosidosis, we tested transfer beta-Gal gene (Glb1) fibroblasts culture...
