PDX-1 was shown to be expressed early during development in cells of both exocrine and endocrine origin; later it becomes restricted primarily to beta-cells where it regulates the expression of beta-cell-specific genes and mediates the glucose effect on insulin gene transcription.

This comparison revealed three short conserved regions, designated PH1, PH2, and PH3.

We showed that HNF-3beta can bind and stimulate the activity of the human PH1 and PH2 elements in non-beta-cells.

Results reported by Wu et al. (7) and Sharma et al. (6) also indicate that expression of the mouse pdx-1 is controlled by an HNF-3-like element.

|
Thus, it can be stated that at least some aspects of pdx-1 expression rely on the transcription factor HNF-3beta.

|
Because HNF-3beta is not restricted to beta-cells, the selective transcription of pdx-1 is likely to rely on additional factors.

|
Our findings that the PH1 enhancer element binds both HNF-3beta and PDX-1 and that mutations in each individual site dramatically impair its transcriptional activity suggest that these factors cooperate with one another.

The activity of serine : pyruvate/alanine : glyoxylate aminotransferase (SPT/AGT) or glyoxylate reductase/hydroxypyruvate reductase (GRHPR), the key enzyme of primary hyperoxlauria type 1 and 2, respectively, and their subcellular distribution highly affects the oxalate production.
