The present invention provides compositions and methods for treating a tissue disorder associated with a response-to-injury process or proliferating cells in a mammal. These tissue disorders are associated with a novel cellular phenotype designated as 'transition cells' which are described herein. This cellular phenotype is characterized in having an activated erk kinase signaling activity, a stimulated AP-1 binding activity, and at least one characteristic selected from the group consisting of: (a) increased podosome formation, (b) increased flux of intracellular or extracellular hyaluronans or hyaladherins, (c) increased expression of a hyaladherin, (d) an inability to form focal adhesions, (e) increased metalloproteinase activity, and (f) increased expression of a hyaladherin. Example tissue disorders include fibrosis, inflammation, degeneration and invasive disorders such as occur in cancerous cells. The methods provided herein include administering to the mammal, an effective amount of a composition that alters the activity of transition molecules within a cell Transition molecules are shown to be comprised of hyaladherins, hyaluronans and associated molecules that regulate the transitional phenotype. A novel cell culture comprising transition cells is also provided, as well as compositions comprising particular peptides, polypeptides, and antibodies that affect the transitional phenotype.

Compositions and methods for treating cellular response to injury and other proliferating cell disorders regulated by hyaladherin and hyaluronans

The present invention provides compositions and methods for treating a tissue disorder associated with a response-to-injury process or proliferating cells in a mammal. The tissue disorders include fibrosis, inflammation, degeneration and invasive disorders such as those occur in cancerous cells. The methods provided herein include administering to the mammal, an effective amount of a composition that alters the activity of transition molecules within a cell. Transition molecules are shown to be comprised of hyaladherins, hyaluronans and associated molecules that regulate the transitional phenotype.

For the prevention of the narrowing of the tubular walls of an animal after the tubular walls have been traumatized, the administration of a therapeutically effective non-toxic amount of a form of Hyaluronic Acid selected from Hyaluronic Acid, salts thereof and combinations thereof to the animal to prevent narrowing of the tubular walls.

Use of hyaluronic acid and forms to prevent the narrowing of the vascular walls

This invention relates to the oral administration of forms of hyaluronic acid (for example hyaluronan (hyaluronic acid) and pharmaceutically acceptable salts thereof such as sodium hyaluronate), and orally administrable dosage forms containing forms of hyalruonic acid, for the prevention and/or treatment of diseases and/or conditions such as the prevention of restenosis and the treatment of an infarct (heart attack) or a stroke. The oral administration and the orally administered dosage forms may also include therapeutic agents and/or medicines which may be administered orally for the treatment and/or prevention of the diseases and/or conditions with the forms of hyaluronic acid (hyaluronan) previously described.

Oral administration of effective amounts of forms of hyaluronic acid

A method of treating a human suffering a disease or condition caused by a gene, cDNA or RNA-DNA oligonucleotide or RNA-DNA oligonucleotide hybrids or messenger RNA implicated in a disease or condition involving cells that express hyaluronic acid receptors is provided, the method comprising administering to such human, an effective dosage amount of a pharmaceutical composition comprising an effective amount of a form of hyaluronic acid selected from hyaluronic acid and/or a pharmaceutically acceptable salt thereof associated with/bound with an effective amount of anti-sense to the gene, cDNA or RNA-DNA oligonucleotide or RNA-DNA oligonucleotide hybrids or messenger RNA implicated in the disease or condition in a suitable pharmaceutically acceptable diluent.

Use of hyaluronan in gene therapy

Novel hyaluronan-binding peptides are provided. The peptides are useful in preventing and treating disorders associated with altered tissue levels of hyaluronan or RHAMM, including cancer, inflammatory and autoimmune disorders and fibrotic disorders associated with tissue trauma.

Enhanced affinity hyaluronan binding peptides

Use of hyaluronic acid and forms to prevent arterial restenosis

A method is provided of preventing arterial restenosis of an animal after the arteries have been traumatized. The method comprises the administration of a therapeutically effective non-toxic amount of hyaluronic acid and/or pharmaceutically acceptable salts thereof to the animal to prevent narrowing of the arteries. The form of hyaluronic acid is selected from hyaluronic acid and pharmaceutically acceptable salts thereof having a molecular weight less than 750,000 daltons.

Hyaluronic acid and salts thereof inhibit arterial restenosis

A method of treating a human having a disease or condition characterized by macrophage, neutrophile or other white blood cell infiltration into the area damaged by the disease or condition, the method comprising administering to the human an effective amount of hyaluronic acid and/or salts thereof for a period of time until the administration is no longer required.

Treatment of disease and conditions associated with macrophage

For the prevention of the narrowing of the tubular walls of an animal after the tubular walls have been traumatized, the administration of a therapeutically effective non-toxic amount of hyaluronic acid and/or salts thereof and/or homologues, analogues, derivatives, complexes, esters, fragments, and subunits of hyaluronic acid to the animal to prevent narrowing of the tubular walls.
