Evaluation of Metals in a Defined Medium for Pichia pastoris Expressing Recombinant β-Galactosidase

open access: yesBiotechnology Progress, 2008
Culture growth and recombinant protein yield of the Pichia pastoris GS115 methanol utilization positive system were studied in response to the types and levels of metals present in the growth medium and the supplemental salts typically used for these fermentations.

The effect of the electric field on lag-phase, ethanol and β-galactosidase production of a recombinant S. cerevisiae growing on lactose [PDF]

open access: yes, 2005
The production of ethanol and β-galactosidase from cheese whey and other sub-products from industries can be a good way of minimizing environmental problems and producing valuable products from low-cost raw materials. A recombinant S.

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.

Axitinib induces DNA damage response leading to senescence, mitotic catastrophe, and increased NK cell recognition in human renal carcinoma cells. [PDF]

open access: yes, 2015
Tyrosine kinase inhibitors (TKIs) including axitinib have been introduced in the treatment of renal cell carcinoma (RCC) because of their anti-angiogenic properties.

DLC2 modulates angiogenic responses in vascular endothelial cells by regulating cell attachment and migration. [PDF]

open access: yes, 2010
Deleted in liver cancer 1 (DLC1) is a RhoGTPase activation protein-containing tumor suppressor that associates with various types of cancer. Although DLC2 shares a similar domain structure with that of DLC1, the function of DLC2 is not well characterized.

Mechanistic Investigation of β-Galactosidase-Activated MR Contrast Agents

open access: yesInorganic Chemistry, 2007
We report a mechanistic investigation of an isomeric series of beta-galactosidase-activated magnetic resonance contrast agents. Our strategy focuses on the synthesis of macrocyclic caged-complexes that coordinatively saturate a chelated lanthanide. Enzyme cleavage of the complex results in an open coordination site available for water that creates a ...

Solid‐state fermentation pro‐enzymes supplementation benefits growth performance, health, and intestinal microbiota of broiler chickens fed wheat‐based diet

open access: yesAnimal Research and One Health, EarlyView.
Wheat as a kind of diet material can be used for broiler production. However, due to non‐starch polysaccharides (NSP) in wheat, wheat may lead to lower growth performance and worth health. This experiment used solid‐state fermentation pro‐enzymes (SFP enzymes) to reverse the negative effect of wheat.
