The disclosure provides methods of preventing or treating Friedreich's ataxia in a mammalian subject, reducing risk factors, signs and/or symptoms associated with Friedreich's ataxia, and/or reducing the likelihood or severity of Friedreich's ataxia. The methods comprise administering to the subject an effective amount of an aromatic-cationic peptide to e.g., reduce oxidative stress, increase mitochondrial metabolism, or a combination thereof.

The invention relates to a homing peptide-guided decorin conjugate for use in the treatment of epidermolysis bullosa, and to a corresponding method of treatment. Use of a novel homing peptide enables target-specific homing of the conjugate to skin and skin wounds in vivo, through systemic administration.

Disclosed are crystalline forms of the bis- and tris-(hydrochloride) salts of D-Arg-Tyr(2,6-DiMe)-Lys-Phe-NH.sub.2, which is also known as MTP-131.

Provided is a cell culture scaffold material having excellent cell adhesion. The cell culture scaffold material according to the present invention contains a peptide-conjugated polyvinyl alcohol derivative having a polyvinyl alcohol derivative portion and a peptide portion, and the peptide portion has a cyclic peptide skeleton.

The present disclosure relates to prostate specific membrane antigen (PSMA) targeted compounds conjugated to near-infra red (NIR) dyes and methods for their therapeutic and diagnostic use. More specifically, this disclosure provides compounds and methods for diagnosing and treating diseases associated with cells and/or vasculature expressing prostate specific membrane antigen (PSMA), such as prostate cancer and related diseases. The disclosure further describes methods and compositions for making and using the compounds, methods incorporating the compounds, and kits incorporating the compounds.

The invention provides a method for treating one or more complications of diabetes in a mammal. The method comprises administering to a mammal in need thereof an effective amount of an aromatic-cationic peptide having at least one net positive charge; a minimum of four amino acids; a maximum of about twenty amino acids; a relationship between the minimum number of net positive charges (p.sub.m) and the total number of amino acid residues (r) wherein 3 p.sub.m is the largest number that is less than or equal to r+1; and a relationship between the minimum number of aromatic groups (a) and the total number of net positive charges (p.sub.t) wherein 2a is the largest number that is less than or equal to p.sub.t+1, except that when a is 1, p.sub.t may also be 1.

Disclosed is a peptide and a cosmetic composition using the same. The peptide inhibits the activity of an aryl hydrocarbon receptor (AhR), whereby the peptide may be used to alleviate skin troubles caused by fine dust.

The disclosure provides methods of preventing or treating Sengers syndrome in a mammalian subject, reducing risk factors associated with Sengers syndrome, and/or reducing the likelihood or severity of Sengers syndrome. The methods comprise administering to the subject an effective amount of an aromatic-cationic peptide to increase expression of AGK in subjects in need thereof.

The invention described herein pertains to the diagnosis, imaging, and/or treatment of pathogenic cell populations. In particular, the invention described herein pertains to the diagnosis, imaging, and/or treatment of diseases caused by PSMA expressing cells, such as prostate cancer cells, using compounds capable of targeting PSMA expressing cells.

Disclosed herein are compositions and methods related to aromatic-cationic peptides. In particular, the compositions and methods relate to aromatic-cationic peptides in conjunction with cytochrome c.
