The purpose of this invention is to provide a method with which it is easy to perform screening for an agent that proliferates or an agent that minimizes the reduction in MCSP-positive basal epidermal stem cells. Provided is a screening method for a laminin 511 expression promoter, which takes the expression of laminin 511 as an indicator. Also provided is an agent for improving skin barrier function, elasticity, hydration and inflammation, said agent including at least one extract selected from among a group consisting of brown algae, red algae and green algae.

A pharmaceutical composition formulated for delivery of a recombinant adeno-associated virus (rAAV) vector comprising an AAV capsid and a vector genome having human galactosylceramidase (GALC) coding sequence is provided. Also provided are 5 methods and uses of a pharmaceutical composition comprising a rAAV for the treatment of Krabbe disease.

The present invention relates to a utilizing method of a nucleic acid compound containing a selectively cleavable site. Also, the present invention relates to a DNA-encoded library containing the selectively cleavable site, a composition for synthesis therefor and a method of use thereof.

Provided herein is a protein, referred to as a Pn3Pase protein, that degrades the capsular polysaccharide of serotype 3 Streptococcus pneumoniae. The disclosure includes a genetically modified cell that includes a Pn3Pase protein, and compositions that include the protein, the polynucleotide encoding the protein, the genetically modified cell, or a combination thereof. Also provided are methods for using a Pn3Pase protein, including methods for contacting a S. pneumoniae having a type III capsular polysaccharide with a Pn3Pase protein, increasing deposition of at least one complement component on the surface of a S. pneumoniae, treating an infection in a subject, treating a symptom in a subject, decreasing colonization of a subject by S. pneumoniae, or a combination thereof.

The present invention relates to a process for producing olive oil by using enzymes.

Some aspects of this disclosure provide compositions, strategies, systems, reagents, methods, and kits that are useful for the targeted editing of nucleic acids, including editing a single site within the genome of a cell or subject, e.g., within the human genome. In some embodiments, fusion proteins capable of inducing a cytosine (C) to guanine (G) change in a nucleic acid (e.g., genomic DNA) are provided. In some embodiments, fusion proteins of a nucleic acid programmable DNA binding protein (e.g., Cas9) and nucleic acid editing proteins or protein domains, e.g., deaminase domains, polymerase domains, and/or base excision enzymes are provided. In some embodiments, methods for targeted nucleic acid editing are provided. In some embodiments, reagents and kits for the generation of targeted nucleic acid editing proteins, e.g., fusion proteins of a nucleic acid programmable DNA binding protein (e.g., Cas9), and nucleic acid editing proteins or domains, are provided.

The present invention relates to mannanase variants. The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the variants.

Methods are provided for the prognosis, diagnosis and treatment of various pathological states, including cancer, chemotherapy resistance and dementia associated with Alzheimer's disease. The methods provided herein are based on the discovery that various proteins with a high level of sialylation are shown herein to be associated with disease states, such as, cancer, chemotherapy resistance and dementia associated with Alzheimer's disease. Such methods provide a lysosomal exocytosis activity profile comprising one or more values representing lysosomal exocytosis activity. Also provided herein, is the discovery that low lysosomal sialidase activity is associated with various pathological states. Thus, the methods also provide a lysosomal sialidase activity profile, comprising one or more values representing lysosomal sialidase activity. A lysosomal sialidase activity profile is one example of a lysosomal exocytosis activity profile.

In one aspect, provided herein are recombinant neuraminidases comprising an ectodomain of influenza virus neuraminidase with amino acid substitutions or insertions of cysteines in the stalk domain to generate a more stable, tetrameric influenza virus neuraminidase. In specific embodiments, the influenza virus neuraminidase further comprises influenza virus neuraminidase transmembrane and cytoplasmic domains. In another aspect, provided herein are recombinant neuraminidase comprising a globular head domain of influenza virus neuraminidase and a tetramerization domain, wherein the recombinant neuraminidase lacks influenza virus neuraminidase stalk, transmembrane and cytoplasmic domains. In another aspect, provided herein are methods of immunizing against influenza virus using such recombinant neuraminidases or compositions thereof.

Hemicellulase that degrades corn non-starch polysaccharides (“NSP”), DNA encoding the same, and a method of using the hemicellulase and its DNA are provided. Proteins having hemicellulase activity such as Xyn5A, Xyn10B, Xyn11A, Xyn30A, and Xyn43A are described.
