Overexpression of matrix metalloproteinase-10 and matrix metalloproteinase-3 in human diabetic corneas: a possible mechanism of basement membrane and integrin alterations.

We have previously described decreased immunostaining of nidogen-1/entactin; laminin chains alpha1, alpha5, beta1,gamma1; and epithelial integrin alpha3beta1 in human diabetic retinopathy (DR) corneas.

By semiquantitative reverse transcription-polymerase chain reaction, gene expression levels of the alpha1, alpha5, and beta1 laminin chains; nidogen-1/entactin; integrin alpha3 and beta1 chains in diabetic and DR corneal epithelium were similar to normal.

Thus, the observed basement membrane and integrin changes were unlikely to occur because of a decreased synthesis. mRNA levels of matrix metalloproteinase-10 (MMP-10/stromelysin-2) were significantly elevated in DR corneal epithelium and stroma, and of MMP-3/stromelysin-1, in DR corneal stroma.

Our previous data suggested the involvement of matrix metalloproteinase-10 (MMP-10) and cathepsin F (CTSF) in the basement membrane and integrin changes occurring in diabetic corneas.

These markers were now examined in normal human organ-cultured corneas upon recombinant adenovirus (rAV)-driven transduction of MMP-10 and CTSF genes.

|
One cornea of each pair was transduced with rAV expressing either CTSF or MMP-10 genes. 1-2 x 10(8) plaque forming units of rAV per cornea were added to cultures for 48 h with or without sildenafil citrate.

|
Corneas transduced with CTSF or MMP-10 genes or their combination had increased epithelial immunostaining of respective proteins compared to fellow control corneas.

|
Staining for diabetic markers integrin alpha(3)beta(1), nidogen-1, nidogen-2, and laminin gamma2 chain became weaker and irregular upon proteinase transduction.

|
The data suggest that MMP-10 and CTSF may be responsible for abnormal marker patterns and impaired wound healing in diabetic corneas.

At 12 weeks, rats given STZ alone revealed an increase in blood glucose and were unaffected by spironolactone, whereas the STZ+SPL group showed considerable improvement in urine albumin and podocyte excretion, as well as up-regulation of integrin alpha 3.
