X-ray structure and function studies of key enzymes for biomass conversion [PDF]
, 2013 The need for large enzyme quantities due to the difficult hydrolysis of recalcitrant polysaccharides is still a major barrier to economical biomass conversion for biofuel production.

Molecular Oncology, EarlyView.Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Challenges in pediatric endothelial keratoplasty
Indian Journal of Ophthalmology, 2014 We performed endothelial keratoplasty (EK) in three eyes of two siblings (2.5 years, male and 3.5 years, female) with congenital hereditary endothelial dystrophy (CHED) and report the intraoperative and postoperative difficulties. Repeated iris prolapse,

Extracellular Enzyme Secretion by Pseudomonas lemoignei [PDF]
Journal of Bacteriology, 1974 The ability of succinate to repress the secretion of Pseudomonas lemoignei poly-β-hydroxybutyrate depolymerase was a function of pH. Repression only occurred when the pH of the medium was 7.0 or less. At a higher pH, lack of sensitivity to succinate concentration may have been due to a limited ability to transport ...

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3
Molecular Oncology, EarlyView.PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer
Molecular Oncology, EarlyView.Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Extracellular enzymes in bioremediation: potential and limitations
, 2016 Bioremediation processes often pivot on the activity of living organisms such as microorganisms, plants, algae. Bioremediation of contaminated soil and water finds very efficient tools in extracellular enzymes.

Degradation of human kininogens with the release of kinin peptides by extracellular proteinases of Candida spp. [PDF]
, 2010 The secretion of proteolytic enzymes by pathogenic microorganisms is one of the most successful strategies used by pathogens to colonize and infect the host organism.
