Effect of mechanical denaturation on surface free energy of protein powders [PDF]

open access: yes, 2016
yesGlobular proteins are important both as therapeutic agents and excipients. However, their fragile native conformations can be denatured during pharmaceutical processing, which leads to modification of the surface energy of their powders and hence ...

Immune-mediated loss of transgene expression from virally transduced brain cells is irreversible, mediated by IFNγ, perforin, and TNFα, and due to the elimination of transduced cells [PDF]

open access: yes, 2012
The adaptive immune response to viral vectors reduces vector-mediated transgene expression from the brain. It is unknown, however, whether this loss is caused by functional downregulation of transgene expression or death of transduced cells.

Senescence Associated β-galactosidase Staining

open access: yesBio-Protocol, 2012
Detection of senescent cells using a cytochemical assay was first described in 1995 (Dimri et al., 1995). The identification of senescent cells is based on an increased level of lysosomal β-galactosidase activity (Kurz et al., 2000).

Study of muscle cell dedifferentiation after skeletal muscle injury of mice with a Cre-Lox system. [PDF]

open access: yesPLoS ONE, 2011
Dedifferentiation of muscle cells in the tissue of mammals has yet to be observed. One of the challenges facing the study of skeletal muscle cell dedifferentiation is the availability of a reliable model that can confidentially distinguish differentiated

Insertion of a 27 amino acid viral peptide in different zones ofEscherichia coliβ-galactosidase: Effects on the enzyme activity [PDF]

open access: yesFEMS Microbiology Letters, 1994
Seven internal, putatively exposed regions of Escherichia coli beta-galactosidase have been explored regarding their tolerance to insertions of large foreign peptides. Small sequence modifications, including amino acid substitutions and small deletions, were introduced into the lacZ gene to generate unique BamHI restriction sites. By using these mutant

Optimised N-acetyl-d-lactosamine synthesis using Thermus thermophilus β-galactosidase in bio-solvents

open access: yesTetrahedron, 2013
Synthesis of N-acetyl-D-lactosamine (Gal-β[1→4]GlcNAc, LacNAc) catalyzed by β-galactosidase from Thermus thermophilus (TTP0042) is affected by side reactions that give as result very low yields (about 20%) of LAcNAc when the reaction is performed in buffer.

The zinc cluster proteins Upc2 and Ecm22 promote filamentation in Saccharomyces cerevisiae by sterol biosynthesis-dependent and -independent pathways. [PDF]

open access: yes, 2015
The transition between a unicellular yeast form to multicellular filaments is crucial for budding yeast foraging and the pathogenesis of many fungal pathogens such as Candida albicans.

Axitinib induces senescence-associated cell death and necrosis in glioma cell lines: The proteasome inhibitor, bortezomib, potentiates axitinib-induced cytotoxicity in a p21(Waf/Cip1) dependent manner. [PDF]

open access: yes, 2017
Glioblastoma is associated with a poor overall survival despite new treatment advances. Antiangiogenic strategies targeting VEGF based on tyrosine kinase inhibitors (TKIs) are currently undergoing extensive research for the treatment of glioma.
