EpoR is thought to contribute to differentiation via multiple signaling pathways including the STAT5 pathway. Credit: Monkeyontheloose.

Although "the P3, P6 substitutions alter the conserved 'GATAAG' I box motif, a 'GATA' motif is present in the introduced EcoRV site. This introduced GATA sequence clearly does not serve as a functional I box [...]."[1]

"The I-box motif, 5'-GGATGAGATAAGA-3', or its shorter version 5'-GATAAG-3', has been found in the promoters of a large number of RBCS genes (Giuliano et al., 1988; Manzara and Gruissem, 1988). A related motif (the GATA box) is present in the promoters of the light-regulated chlorophyll a/b binding protein (CAB) genes of different species (Gidoni et al., 1989), and has been shown to be involved in the activation of an Arabidopsis CAB gene by light and by the circadian clock (Anderson and Kay, 1995). I-box and GATA binding factors have been identified in nuclear extracts from tobacco and tomato leaves and cotyledons (Borello et al., 1993; Giuliano et al., 1988; Manzara et al., 1991; Schindler and Cashmore, 1990). The I-box has therefore been suggested to be involved in light-regulated and/or leaf-specific gene expression of photosynthetic genes (Manzara et al., 1991), but to date no I-box binding protein has been cloned from plants."[2]

SRF is important during the development of the embryo, as it has been linked to the formation of mesoderm.[3][4]

The Serum response factor (SRF) has been shown to interact with GATA4.[5][6]

Cell specific developmental expression is tightly controlled, but, once expressed, require no additional activation -- GATA transcription factor (GATA), hepatocyte nuclear factors (HNF), PIT-1, MyoD, Myf5, Hox, winged-helix transcription factors.

The class of diverse Cys4 zinc fingers includes the family of GATA-factors.

In the diagram on the right, STAT5 may be involved with an erythropoiesis receptor, or Epo Receptor. Murine, members of the subfamily Murinae, Epo Receptor truncations and known functions are included. Erythroid differentiation depends on transcriptional regulator GATA1, zinc finger DNA binding domain binds specifically to DNA consensus sequence [AT]GATA[AG] promoter elements. In erythropoiesis, EpoR is best known for inducing survival of progenitors.

Some "putative wound-response elements including AGC box-like sequences28, TCA motif-like sequences28, carrot extensin gene wound-response elements (AT-rich motif, TTTTTTT, TGACGT)29, constitutive PAL footprint and elicitor-inducible PAL footprint31, and proteinase inhibitor II footprint31 have been found in cabch29 promoter. Some cis-elements related to organ and tissue-specific expression such as GATA motif-like sequence, ASF-1 binding site-like elements also existed in 5′ upstream region. Meanwhile, some basic transcriptional regulatory cis-elements including G box-like and GC box-like elements are located in this region."[7]

"A computer search for transcription promoter elements [...] showed the presence of a prominent TATA box 22 nucleotides upstream of the transcription start site and an Sp1 site at position -42 to -33. The 5'-flanking sequence also contains three E boxes with CANNTG consensus sequences at positions -464 to -459, -90 to -85, and -52 to -47 that have been marked as E box, E1 box, and E2 box, respectively [...]. In addition, the 5'-flanking region contains one or more GRE, XRE, GATA-1, GCN-4, PEA-3, AP1, and AP2 consensus motifs and also three imperfect CArG sites [...]."[8]

Single transcription factor transdifferentiation

Brief expression of a single transcription factor, the ELT-7 GATA factor, can convert the identity of fully differentiated, specialized non-endodermal cells of the pharynx into fully differentiated intestinal cells in intact larvae and adult roundworm Caenorhabditis elegans with no requirement for a dedifferentiated intermediate.[9]

"ELT-7, a GATA transcription factor that regulates terminal intestinal differentiation (Maduro and Rothman, 2002; Sommermann et al., 2010), activates an intestinal marker (elt-2::lacZ::GFP) in non-intestinal cells when briefly ectopically expressed via a heat-shock promoter at any embryonic, larval, or adult stage [...]."[9]

The "END-1 GATA transcription factor, which specifies the endoderm progenitor (Zhu et al., 1997), does not activate widespread intestinal gene expression after the MCT [...]."[9]

Cardiomyocytes

Cell-based in vivo therapies may provide a transformative approach to augment vascular and muscle growth and to prevent non-contractile scar formation by delivering transcription factors[10] or microRNAs[11] to the heart.[12] Cardiac fibroblasts, which represent 50% of the cells in the mammalian heart, can be reprogrammed into cardiomyocyte-like cells in vivo by local delivery of cardiac core transcription factors (GATA4, MEF2C, TBX5 and for improved reprogramming plus ESRRG, MESP1, Myocardin and ZFPM2) after coronary ligation.[10][13] These results implicated therapies that can directly remuscularize the heart without cell transplantation. However, the efficiency of such reprogramming turned out to be very low and the phenotype of received cardiomyocyte-like cells does not resemble those of a mature normal cardiomyocyte. Furthermore, transplantation of cardiac transcription factors into injured murine hearts resulted in poor cell survival and minimal expression of cardiac genes.[14]

Blood stem cells

Definitive hematopoiesis emerges during embryogenesis via an endothelial-to-hematopoietic transition. Combination of four transcription factors, GATA2, GFI1B, c-Fos, and ETV6, is sufficient to induce in vitro development leading to the formation of endothelial-like precursor cells, with the subsequent appearance of hematopoietic cells.[15] Transient expression of six transcription factors (RUNX1T1, HLF, LMO2, Prdm5, PBX1, ZFP36) and also N-Myc with MEIS1, to improve reprogramming efficacy, is sufficient to activate the gene networks governing hematopoietic stem cells functional identity in committed blood cells. This finding marks a significant step toward one of the most sought-after goals of regenerative medicine: the ability to produce hematopoietic stem cells suitable for transplantation, using more mature or differentiated blood cells to make up the shortfall of bone marrow transplants[16] It should be noted, however, that the transcription factors used in this study belong to a group of proto-oncogenes and therefore these cells could be dangerous to humans. Still to be answered are the precise contribution of each of the eight factors to the reprogramming process and whether approaches that do not rely on viruses and transcription factors can have similar success. It also is not yet known whether the same results can be achieved using human cells or whether other, non-blood cells can be reprogrammed to iHSCs.[17]
