Peptides having general and specific binding affinities for the Src homology region 3 (SH3) domains of proteins are disclosed in the present invention. In particular, SH3 binding peptides have been isolated from phage-displayed random peptide libraries which had been screened for isolates that bind to bacterial fusion proteins having an SH3 domain and glutathione S-transferase (GST). Preferred peptides are disclosed which comprise a core 7-mer sequence (preferably, a consensus motif) and two or more, preferably at least six, additional amino acid residues flanking the core sequence, for a total length of 9, preferably at least 13, amino acid residues and no more than about 45 amino acid residues. Such peptides manifest preferential binding affinities for certain SH3 domains. The preferred peptides exhibit specific binding affinities for the Src-family of proteins. In vitro and in vivo results are presented which demonstrate the biochemical activity of such peptides.

The invention provides a method to treat or prevent posterior capsular opacification. The method comprises administering a therapeutically or prophylactically effective amount of a pharmaceutical composition comprising at least one kinase inhibitor. The kinase inhibitor inhibits p38 kinases, ERK kinases, and/or Src family kinases. The invention also provides an ocular device coated with at least one kinase inhibitor.

A method for regulating Src and its downstream signaling pathway which includes binding between Src and Na+/K+-ATPase is disclosed. The Na+/K+-ATPase/Src complex is a functional receptor for cardiotonic steroids such as ouabain. Also disclosed are Src inhibitors or activators which include either Na+/K+-ATPase or Src that interfere with the interaction between the Na/K-ATPase and Src, act via a different mechanism from ATP analogues, and is pathway (Na+/K+-ATPase) specific.

Applicants have used microarrays, gene expression profiling, and gene silencing methods to identify and provide a plurality of ‘validated’ virus-induced cellular gene sequences (e.g., HMG20B, HRH1, NP and c-YES (src family kinases)) and pathways useful as therapeutic targets for modulation of viral-mediated cellular effects. Particular embodiments provide therapeutic compositions, and methods for modulation of viral infection, replication, maturation, progression, or other virally-related conditions or diseases, comprising inhibition of virally-induced gene sequences and gene products. Additional embodiments provide screening assays for compounds useful to modulate viral infection, replication, maturation or progression, or viral-related conditions or diseases. Further embodiments provide diagnostic and/or prognostic assays for viral infection, replication, maturation or progression. Preferably, the viruses all selected from the group consisting of retroviruses (e.g., human immunodeficiency virus (HIV), and viruses of the family Flaviviridae that includes the flaviviruses (e.g., West Nile virus (WNV), Japanese encephalitis virus (JEV), yellow fever virus (YFV) and Dengue fever virus (DEN)), and hepatitis C virus (HCV).

There are provided compounds of formula I, wherein R¹, R^1A, R^1C to R^1E, R^a, R^b, X¹, E and G have meanings given in the description, which compounds have antiinflammatory activity (e.g., through inhibition of one or more of members of: the family of p38 mitogen-activated protein kinase enzymes; Syk kinase; and members of the Src family of tyrosine kinases) and have use in therapy, including in pharmaceutical combinations, especially in the treatment of inflammatory diseases, including inflammatory diseases of the lung, eye and intestines.

The invention relates to a construction method for streptomycete expression plasmids and a production method for keratinase. The construction method for streptomycete expression plasmids includes the following steps: a promoter Xi of actinoplanes missouriensis xylose isomerase and a terminator of streptomycete avermitilis amylase are sleeved, and the promoter-shine-dalgarno (SD) sequence comes from 90 to 269bp of an actinoplanes missouriensis xylose isomerase gene; a cloned src family kinases (sfks) gene is inserted in a construction expression frame structure of a synthetic Xi promoter-SD-amyA2 terminator fragment, and then a conventional method is used for constructing the streptomycete expression plasmids. The production method for keratinase includes: leading the streptomycete expression plasmids into an expression host of streptomycete lividans TK24 through conjugal transfer, performing recombinant expression and generating the keratinase. Specific activity of a crude enzyme solution is 1700 U/mg after expression of the expression plasmids in the streptomycete lividans TK24 and is improved by 50 times compared with specific activity of starting strain streptomycete fradiae varieties S-221, and yield of the keratinase is much higher than starting strains after the expression.

The present invention describes polynucleotides that have been discovered to correlate to the relative sensitivity or resistance of cells, e.g., breast cell lines, to treatment with compounds that interact with and modulate, e.g., inhibit, protein tyrosine kinases, such as, for example, members of the Src family of tyrosine kinases, e.g., Src, Fgr, Fyn, Yes, Blk, Hck, Lck and Lyn, as well as other protein tyrosine kinases, including, Bcr-abl, Jak, PDGFR, c-kit and Eph receptors. These polynucleotides have been shown to have utility in predicting the resistance and sensitivity of breast cell lines to the compounds. Such polynucleotides comprise polynucleotide predictor or marker sets useful in methods of predicting drug response, and as prognostic or diagnostic indicators in disease management, particularly in those disease areas, e.g., breast cancer, in which signaling through one or more of the aforementioned Src tyrosine and protein tyrosine kinases is involved with the disease process.
