Human Forkhead-box (FOX) gene family consists of at least 43 members, including FOXA1, FOXA2, FOXA3, FOXB1, FOXC1, FOXC2, FOXD1, FOXD2, FOXD3, FOXD4, FOXD5 (FOXD4L1), FOXD6 (FOXD4L3), FOXE1, FOXE2, FOXE3, FOXF1, FOXF2, FOXG1 (FOXG1B), FOXH1, FOXI1, FOXJ1, FOXJ2, FOXJ3, FOXK1, FOXK2, FOXL1, FOXL2, FOXM1, FOXN1, FOXN2 (HTLF), FOXN3 (CHES1), FOXN4, FOXN5 (FOXR1), FOXN6 (FOXR2), FOXO1 (FOXO1A), FOXO2 (FOXO6), FOXO3 (FOXO3A), FOXO4 (MLLT7), FOXP1, FOXP2, FOXP3, FOXP4, and FOXQ1. FOXE3-FOXD2 (1p33), FOXQ1-FOXF2-FOXC1 (6p25.3), and FOXF1-FOXC2-FOXL1 (16q24.1) loci are FOX gene clusters within the human genome. Members of FOX subfamilies A-G, I-L and Q were grouped into class 1 FOX proteins, while members of FOX subfamilies H and M-P were grouped into class 2 FOX proteins. C-terminal basic region within the FOX domain was the common feature of class 1 FOX proteins. FOXH1 and FOXO1 mRNAs are expressed in human embryonic stem (ES) cells. FOXC1, FOXC2, FOXE1, FOXE3, FOXL2, FOXN1, FOXP2 and FOXP3 genes are mutated in human congenital disorders. FOXA1 gene is amplified and over-expressed in esophageal and lung cancer. FOXM1 gene is up-regulated in pancreatic cancer and basal cell carcinoma due to the transcriptional regulation by Sonic Hedgehog (SHH) pathway. FOXO1 gene is fused to PAX3 or PAX7 genes in rhabdomyosarcoma. FOXO3 and FOXO4 genes are fused to MLL gene in hematological malignancies. Deregulation of FOX family genes leads to congenital disorders, diabetes mellitus, or carcinogenesis. Expression profiles, genetic alterations and epigenetic changes of FOX family genes as well as binding proteins and target genes of FOX family transcription factors should be comprehensively investigated to develop novel therapeutics and preventives for human diseases.

The number of kidney podocytes is reduced in diabetic nephropathy. Advanced glycation end products (AGEs) accumulate in patients with diabetes and promote the apoptosis of podocyte by activating the forkhead box O4 (Foxo4) transcription factor to increase the expression of a pro-apoptosis gene, Bcl2l11. Using chromatin immunoprecipitation we demonstrate that AGE-modified bovine serum albumin (AGE-BSA) enhances Foxo4 binding to a forkhead binding element in the promoter of Bcl2lll. AGE-BSA also increases the acetylation of Foxo4. Lysine acetylation of Foxo4 is required for Foxo4 binding and transcription of Bcl2l11 in podocytes treated with AGE-BSA. The expression of a protein deacetylase that targets Foxo4 for deacetylation, sirtuin (Sirt1), is down regulated in cultured podocytes by AGE-BSA treatment and in glomeruli of diabetic patients. SIRT1 over expression in cultured murine podocytes prevents AGE-induced apoptosis. Glomeruli isolated from diabetic db/db mice have increased acetylation of Foxo4, suppressed expression of Sirt1, and increased expression of Bcl2l11 compared to non-diabetic littermates. Together, our data provide evidence that alteration of Foxo4 acetylation and down regulation of Sirt1 expression in diabetes promote podocyte apoptosis. Strategies to preserve Sirt1 expression or reduce Foxo4 acetylation could be used to prevent podocyte loss in diabetes.
