摘要:
The present invention relates to short peptides based on the amino acids sequence of the N-terminal domain of the human mitochondrial protein voltage-dependent anion channel 1 (VDAC) and to peptide conjugates having a cell permeability enhancing moiety. The peptides, peptide conjugates and pharmaceutical compositions containing them are useful for treating diseases characterized by cell hyperproliferation or resistance to cell death and in particular, cancer.
摘要:
By a pharmaceutical composition for nasal administration comprising a hydrophilic bioactive substance and any one of (a) to (c) below, a hydrophilic bioactive substance having a low transmucosal absorption capability which has conventionally been able to be administered by only injection can be nasally administered. Such a pharmaceutical composition is useful for improvement of the pain and the inconvenience of patients caused by administration by injection. (a) A peptide having the amino acid sequence shown in SEQ ID NO: 1. (b) A peptide having the same amino acid sequence as shown in SEQ ID NO: except that one or several amino acids are deleted, substituted and/or added, the peptide having nasal mucosal permeability. (c) A peptide having an amino acid sequence represented by the reverse sequence of (a) or (b), the peptide having nasal mucosal permeability.
摘要:
The present invention relates to fusion proteins comprising anti-Oomycotic proteins or peptides linked to an antibody or fragment thereof specifically recognising an epitope of an Oomycota . The invention is also directed to polynucleotides coding for the fusion proteins. The embodiments of the present invention are particularly useful for the protection of plants against Oomycota . The invention therefore comprises transgenic plants expressing the fusion proteins of the present invention.
摘要:
H-NOX proteins are mutated to exhibit improved or optimal kinetic and thermodynamic properties for blood gas O 2 delivery. The engineered H-NOX proteins comprise mutations that impart altered O 2 or NO ligand-binding relative to the corresponding wild-type H-NOX domain, and are operative as physiologically compatible mammalian blood O 2 gas carriers. The invention also provides pharmaceutical compositions, kits, and methods that use wild-type or mutant H-NOX proteins for the treatment of any condition for which delivery of O 2 is beneficial.
摘要:
A method for the identification of genes involved in neurodegenerative processes, detectable by the late onset of a phenotype associated with neurodegeneration, by means of a genetic screen of deregulated genes, which comprises the measurement of sleep-wake cycle activity schemes in different stages of life, young and adult, of individuals of an animal model, such as Drosophila. A mutant fly whose genome comprises a disruption in its enabled gene, with decrease of the enabled gene expression, and exhibiting a late onset neurodegenerative phenotype in adulthood.
摘要:
An isolated nucleic acid molecule comprising, or consisting of, a polynucleotide sequence encoding an oligopeptide capable of inducing post-mating depression of receptivity to mating in female insects, wherein said oligopeptide is resistant to proteolytic degradation, is provided for expression in sterile transgenic male insects useful in the control of insect populations.
摘要:
The present invention relates to pharmaceutical compositions comprising a fragment of Serrate protein or a derivative or analog of said fragment, or comprising a derivative or analog of a Serrate protein, or comprising a protein comprising such a fragment, derivative or analog, the fragments, derivatives, analogs and proteins being characterized by the ability in vitro, when expressed on the surface of a first cell, to bind to a Notch protein expressed on the surface of a second cell. The invention also relates to chimeric proteins comprising said Serrate fragments joined via a peptide bond to a protein sequence of a protein different from the Serrate protein, and to nucleic acids encoding said fragments of a Serrate protein, and encoding said chimeric proteins. According to the invention, said fragments, derivatives, analogs, and proteins, said chimeric proteins and said nucleic acids may be used as a medicament, for example, in treating or preventing malignancy in a subject.
