Abstract
Accurate diagnosis of neuroblastoma may be challenging, especially with limited or inadequate specimen and at the metastatic sites due to overlapping imaging, histopathologic, and immunohistochemical (immunohistochemistry [IHC]; infidelity among various lineage-associated transcription factors eg FLI1, transducin-like enhancer 1, etc) features. GATA3 and ISL1 have recently been described as markers of neuroblastic differentiation. This study aims at determining the diagnostic utility of GATA3 and ISL1 in differentiating neuroblastoma from other pediatric malignant small round blue cell tumors. We evaluated GATA3 and ISL1 expression in 74 pediatric small round blue cell tumors that included 23 NMYC-amplified neuroblastomas, 11 EWSR1-rearranged round cell sarcomas, 7 SYT::SSX1-rearranged synovial sarcomas, 5 embryonal rhabdomyosarcomas, 10 Wilms tumors (nephroblastomas), 7 lymphoblastic lymphoma, 7 medulloblastoma, and 4 desmoplastic small round cell tumor. All 23 neuroblastomas (moderate to strong staining in >50% of the tumor cells), 5 T-lymphoblastic lymphomas (moderate to strong staining in 40%-90% of the tumor cells), and 2 desmoplastic small round cell tumors (weak to moderate staining in 20%-30% of the tumor cells) expressed GATA3, while other tumors were negative. ISL1 immunoreactivity was observed in 22 (96%) neuroblastomas (strong staining in in >50% of the tumor cells, n = 17; moderate to strong staining in 26%-50% of the tumor cells, n = 5), 3 embryonal rhabdomyosarcoma (moderate to strong staining in 30%-85% of the tumor cells), 1 synovial sarcoma (weak staining in 20% of the tumor cells), and 7 medulloblastoma (strong staining in 60%-90% of the tumor cells). Other tumors were negative. Overall, GATA3 showed 86% specificity, 100% sensitivity, and 90% accuracy for neuroblastoma, with a positive predictive value (PPV) and negative predictive value (NPV) of 77% and 100%, respectively. ISLI showed 72% specificity, 96% sensitivity, and 81% accuracy for neuroblastoma, with a PPV and NPV of 67% and 97%, respectively. After the exclusion of T-lymphoblastic lymphoma and desmoplastic small round cell tumors, GATA3 had 100% specificity, sensitivity, accuracy, and PPV and NPV for neuroblastoma. Similarly, in pediatric small round blue cell tumors, ISL1 had 100% specificity, sensitivity, accuracy, PPV, and NPV for neuroblastoma, after embryonal rhabdomyosarcoma, synovial sarcoma, and medulloblastoma were excluded. CONCLUSIONS GATA3 and ISL1 may be valuable in the diagnostic work-up of neuroblastoma and may reliably be used to support the neuroblastic lineage of pediatric small round blue cell tumors. Furthermore, dual positivity helps in challenging scenarios, when there is equivocal imaging, overlapping IHC features, limited specimen, and the lack of facility for a molecular work up.

Abstract
GATA3 is the most used marker to determine tumors' breast origin, but its diagnostic value in triple-negative breast cancer (TNBC) is limited. The newly identified TRPS1 is highly sensitive and specific for breast carcinoma, especially TNBC. Here, we compared the utility of TRPS1 and GATA3 expression in a subset of salivary gland-type breast tumors (including adenoid cystic, acinic cell, and secretory carcinomas [AdCC, ACC, and SC, respectively]), and we compared TRPS1 and GATA3 expression of such tumors with head and neck (H&N) and AdCC of upper respiratory tumors. TRPS1 was strongly expressed in basaloid TNBC and AdCCs with solid components, including 100 % of mixed and solid breast AdCCs. However, TRPS1 was positive in only 50 % cribriform AdCCs. Expression patterns of TRPS1 in H&N and upper respiratory AdCC were similar. TRPS1 was positive in 30 % of H&N cribriform AdCCs but was strongly expressed in mixed AdCC (67 %) and solid AdCC (100 %). In the upper respiratory AdCCs, TRPS1 was positive in 58.4 % of cribriform AdCCs and positive in 100 % of AdCCs with solid components. On the contrary, GATA3 was negative in predominant AdCCs of the breast, H&N, and upper respiratory tract. These data show that GATA3 and TRPS1 expression varies AdCCs. In addition, TRPS1 and GATA3 expression patterns were similar SC and ACC of breast and H&N. Both markers were positive in SC and negative in ACC. Therefore, TRPS1 and GATA3 cannot be used to differentiate salivary gland-type carcinomas of breast origin from those of upper respiratory or H&N origin.

Abstract
BACKGROUND & AIMS Post-hepatectomy liver failure (PHLF) leads to poor prognosis in patients undergoing hepatectomy, with hepatic vascular reconstitution playing a critical role. However, the regulators of hepatic vascular reconstitution remain unclear. In this study, we aimed to investigate the regulatory mechanisms of hepatic vascular reconstitution and identify biomarkers predicting PHLF in patients undergoing hepatectomy. METHODS Candidate genes that were associated with hepatic vascular reconstitution were screened using adeno-associated virus vectors in Alb-Cre-CRISPR/Cas9 mice subjected to partial hepatectomy. The biological activities of candidate genes were estimated using endothelial precursor transfusion and associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) models. The level of candidates was detected in biopsies from patients undergoing ALPPS. Risk factors for PHLF were also screened using retrospective data. RESULTS Downregulation of Gata3 and upregulation of Ramp2 in hepatocytes promoted the proliferation of liver sinusoidal endothelial cells and hepatic revascularization. Pigment epithelium-derived factor (PEDF) and vascular endothelial growth factor A (VEGFA) played opposite roles in regulating the migration of endothelial precursors from bone marrow and the formation of new sinusoids after hepatectomy. Gata3 restricted endothelial cell function in patient-derived hepatic organoids, which was abrogated by a Gata3 inhibitor. Moreover, overexpression of Gata3 led to higher mortality in ALPPS mice, which was improved by a PEDF-neutralizing antibody. The expression of Gata3/RAMP and PEDF/VEGFA tended to have a negative correlation in patients undergoing ALPPS. A nomogram incorporating multiple factors, such as serum PEDF/VEGF index, was constructed and could efficiently predict the risk of PHLF. CONCLUSIONS The balance of Gata3 and Ramp2 in hepatocytes regulates the proliferation of liver sinusoidal endothelial cells and hepatic revascularization via changes in the expression of PEDF and VEGFA, revealing potential targets for the prevention and treatment of PHLF. IMPACT AND IMPLICATIONS In this study, we show that the balance of Gata3 and Ramp2 in hepatocytes regulates hepatic vascular reconstitution by promoting a shift from pigment epithelium-derived factor (PEDF) to vascular endothelial growth factor A (VEGFA) expression during hepatectomy- or ALLPS (associating liver partition and portal vein ligation for staged hepatectomy)-induced liver regeneration. We also identified serum PEDF/VEGFA index as a potential predictor of post-hepatectomy liver failure in patients who underwent hepatectomy. This study improves our understanding of how hepatocytes contribute to liver regeneration and provides new targets for the prevention and treatment of post-hepatectomy liver failure.

Abstract
Fumarate hydratase deficient renal cell carcinoma (FHRCC) can exhibit a heterogenous immunoprofile. In the present case, a solitary 10.5 cm mixed cystic and solid left kidney tumor showed various growth patterns, involving renal sinus adipose tissue and the renal pelvis. Tumor cells showed prominent nucleoli and perinucleolar halos. Aberrant diffuse (>90%), strong, and membranous carbonic anhydrase 9 and variable GATA3 expression were present. Diagnostic loss of fumarate hydratase expression and 2-succinyl cysteine overexpression (cytoplasmic and nuclear) were identified. Carbonic anhydrase 9 and GATA3 expression in FHRCC is rarely reported in the literature, and may cause misdiagnosis of clear cell RCC and/or urothelial carcinoma.

Abstract
The choice of therapy for muscle-invasive bladder cancer (MIBC) could be influenced by the tumor's molecular subtype. Currently, well-defined consensus subtypes are based on tumor microarray mRNA data. Clearly defined and easy-to-use surrogate molecular subtypes, based on immunohistochemistry (IHC) performed on whole slides, are needed to make subtyping cost-effective and useful in routine work and future research. To aid in the development of a simple immunohistochemical classifier, a retrospective single-center series of 92 cases of localized bladder cancer was identified. Routine IHC for GATA3, cytokeratins 5 and 6 (CK5/6), and p16 was performed on whole tissue blocks containing muscle-invasive disease. Electronic medical records were retrieved and searched for clinical variables, treatment, and survival data. The mean age was 69.6 years, and 73% were males. Conservative treatment was used in 55% of cases, while cystectomy with chemotherapy was used in 45%. GATA3 and CK5/6 expression divided cases into broad luminal and basal subtypes, respectively, while p16 expression was used to subclassify luminal cases into luminal papillary and luminal unstable types according to the consensus molecular classification. When subtyped in this way, GATA3 and CK5/6 negative cases showed worse overall survival. Molecular subtyping of MIBC on whole slides containing muscle-invasive tumor using only three commonly used, consensus-based antibodies, is a feasible and cost-effective method for detecting subtypes of invasive bladder cancer. Future work combining morphological analysis and IHC is needed to fully translate the consensus molecular classification into a comprehensive, cost-effective subtyping strategy.

Abstract
This study aimed to evaluate the diagnostic and prognostic roles of GATA-binding protein 3 (GATA3) immunohistochemistry in urothelial carcinoma (UC) using a meta-analysis. We investigated GATA3 immunohistochemical expression rates and performed a subgroup analysis based on tumor site, study location, and histological subtypes. The overall survival rates of patients with GATA3-positive and -negative UC were compared. The estimated GATA3 expression rate was 0.748 (95% confidence interval [CI]: 0.704-0.787). GATA3 expression rates in the urinary bladder and urinary tract were 0.775 (95% CI: 0.727-0.818) and 0.614 (95% CI: 0.426-0.774), respectively. The GATA3 expression rates of noninvasive and invasive UCs were 0.965 (95% CI: 0.938-0.980) and 0.644 (95% CI: 0.581-0.702), respectively. In invasive UCs, there was a significant difference in GATA3 expression between non-muscular invasion and muscular invasion subgroups (0.937, 95% CI: 0.883-0.967 vs. 0.753, 95% CI: 0.645-0.836). GATA3 expression was the highest in the microcytic subtype among the histologic subtypes (0.952, 95% CI: 0.724-0.993). There was a significant correlation between GATA3 expression and better prognosis (hazard ratio: 0.402, 95% CI: 0.311-0.521). Taken together, GATA3 expression significantly correlated with low-stage and better prognosis in UC. GATA3 expression is highly variable across histological subtypes, and one should be careful while interpreting GATA3 expression.

Abstract
Currently, there is a paucity of highly specific and sensitive markers to identify breast carcinoma in male patients. Immunohistochemical stains commonly used for unmasking primary breast carcinomas include estrogen receptor (ER) and GATA3. However, these markers are commonly expressed in carcinomas originating from other organ systems and can be reduced in breast carcinomas with higher histologic grades. Androgen receptor (AR) may be used to highlight primary male breast cancer, but this marker can also be expressed in other carcinomas. We evaluated TRPS1, a highly sensitive and specific marker for female breast carcinoma, in cases of male breast carcinoma. Through an institutional database search, we identified 72 cases of primary invasive breast carcinoma in male patients. Among ER/progesterone receptor (PR)-positive cancers, 97% showed intermediate or high positivity for both TRPS1 and GATA3. Among HER2-positive cancers, 100% showed intermediate or high positivity for TRPS1 and GATA3. One case of triple-negative breast cancer was collected, showing high positivity for TRPS1 and negativity for GATA3. AR staining was non-specific and heterogeneous: 76% showed high positivity, but the remaining 24% showed low or intermediate positivity. Additionally, among 29 cases of metastatic carcinoma to male breast tissue, 93% were negative for TRPS1, and the remaining 2 cases (7%), which were carcinomas from salivary gland primary tumors, were intermediate positive. TRPS1 is a sensitive and specific marker in the unmasking of male primary invasive breast carcinoma across different subtypes. Additionally, TRPS1 is not expressed in metastatic carcinomas of multiple primaries, with the exception of salivary gland primaries.

Abstract
INTRODUCTION GATA3 is a transcription factor involved in epithelial cell differentiation. GATA3 immunostaining is used as a diagnostic marker for breast and urothelial cancer but can also occur in other neoplasms. METHODS To evaluate GATA3 in normal and tumor tissues, a tissue microarray containing 16,557 samples from 131 different tumor types and subtypes and 608 samples of 76 different normal tissue types was analyzed by immunohistochemistry. RESULTS GATA3 positivity was found in 69 different tumor types including 23 types (18%) with at least one strongly positive tumor. Highest positivity rates occurred in noninvasive papillary urothelial carcinoma (92-99%), lobular carcinoma (98%), carcinoma of no special type of the breast (92%), basal cell carcinoma of the skin (97%), invasive urothelial carcinoma (73%), T-cell lymphoma (23%), adenocarcinoma of the salivary gland (16%), squamous cell carcinoma of the skin (16%), and colorectal neuroendocrine carcinoma (12%). In breast cancer, low GATA3 staining was linked to high pT stage (p = 0.03), high BRE grade (p < 0.0001), HER2 overexpression (p = 0.0085), estrogen and progesterone receptor negativity (p < 0.0001 each), and reduced survival (p = 0.03). CONCLUSION Our data demonstrate that GATA3 positivity can occur in various tumor entities. Low levels of GATA3 reflect cancer progression and poor patient prognosis in breast cancer.

Abstract
OBJECTIVE Mycosis fungoides (MF) is the most common type of cutaneous lymphoma. The early stage of MF is a difficult diagnostic case, as it is often confused with many benign inflammatory dermatoses (BID). The study aimed to evaluate the diagnostic utility of TOX, FOXP3, CDD4 and GATA3 in differentiating early stages of MF from histologically overlapping BID lesions. MATERIAL AND METHOD A retrospective cross-sectional study was performed, in which immunohistochemistry (IHC) was used to evaluate the expression of TOX, FOXP3, CD4 and GATA3 in formalin-fixed paraffin-embedded (FFPE) sections of skin lesions from 30 cases with BID and 30 patients with early-stage MF. RESULTS The association between TOX expression and early-stage MF was statistically significant (P < 0.001). TOX had the highest sensitivity of 96.77% and accuracy of 85.71% in diagnosis of MF; followed by CD4 with sensitivity of 85.71% and accuracy of 78.95%; and then, GATA3 with sensitivity of 76.7% and finally FOXP3 with sensitivity of 70.0%. CONCLUSION TOX is suggested to be of higher diagnostic value in the early stages of MF than the conventionally used CD4 and other markers examined.

Abstract
Objective: To investigate the expression characteristics of SOX10 and GATA3 in breast cancer and the value of their combination. Methods: A total of 360 breast cancer specimens with SOX10 immunohistochemical staining were collected from the Department of Pathology in Shenzhen People's Hospital from 2018 to 2021, including 268 cases with simultaneous SOX10 and GATA3 staining. The expression of SOX10 and GATA3 in primary and metastatic breast cancer was detected, and the correlations between SOX10 and GATA3 and the molecular types and clinicopathological features of breast cancer were compared, and the distribution differences among each group were statistically analyzed. Results: The overall expression of SOX10 and GATA3 in breast cancer were 25.8%(93/360) and 81.7%(219/268), and that in triple negative breast cancer (TNBC) were 83.3%(80/96) and 42.7%(32/75), respectively. SOX10 was strongly associated with TNBC (P<0.001), whereas GATA3 was highly expressed in luminal A, luminal B and HER2 over expression breast cancers (P<0.001). The expression of SOX10 and GATA3 was negatively correlated in TNBC, and the combined expression rates of SOX10 and GATA3 in breast cancer and TNBC could reach 97.8% (262/268) and 94.7%(71/75), respectively. In addition, the expression of SOX10 was closely correlated with high histological grade, high Ki-67 proliferation index and lymph node metastasis, and negatively correlated with AR. The expression of GATA3 was correlated with low histological grade and lymph node metastasis, and positively correlated with AR, and the difference was statistically significant. Conclusions: SOX10 is a sensitive marker of TNBC, while GATA3 is highly expressed in non-triple negative breast cancer. The two complementary, combined application of SOX10-GATA3 can improve the detection rate of breast cancer, especially TNBC. SOX10 is associated with malignant characteristics of the tumor, suggesting that SOX10 can be used as a prognostic marker and potential therapeutic target for breast cancer.

Abstract
Proper ectodermal patterning during human development requires previously identified transcription factors such as GATA3 and p63, as well as positional signalling from regional mesoderm1-6. However, the mechanism by which ectoderm and mesoderm factors act to stably pattern gene expression and lineage commitment remains unclear. Here we identify the protein Gibbin, encoded by the Xia-Gibbs AT-hook DNA-binding-motif-containing 1 (AHDC1) disease gene7-9, as a key regulator of early epithelial morphogenesis. We find that enhancer- or promoter-bound Gibbin interacts with dozens of sequence-specific zinc-finger transcription factors and methyl-CpG-binding proteins to regulate the expression of mesoderm genes. The loss of Gibbin causes an increase in DNA methylation at GATA3-dependent mesodermal genes, resulting in a loss of signalling between developing dermal and epidermal cell types. Notably, Gibbin-mutant human embryonic stem-cell-derived skin organoids lack dermal maturation, resulting in p63-expressing basal cells that possess defective keratinocyte stratification. In vivo chimeric CRISPR mouse mutants reveal a spectrum of Gibbin-dependent developmental patterning defects affecting craniofacial structure, abdominal wall closure and epidermal stratification that mirror patient phenotypes. Our results indicate that the patterning phenotypes seen in Xia-Gibbs and related syndromes derive from abnormal mesoderm maturation as a result of gene-specific DNA methylation decisions.

Abstract
Sinonasal neuroendocrine neoplasms (SN-NENs) are rare and mostly include neuroendocrine carcinoma (NEC), whereas neuroendocrine tumor (NET) is exceptional in this site. Olfactory neuroblastoma (ONB) is a malignant neuroectodermal neoplasm arising in the nasal cavity. Albeit crucial for correct patients' management, the distinction of high grade ONB from NEC is challenging and requires additional diagnostic markers. The transcription factor SATB2 has been recently introduced in routine diagnostics as an immunohistochemical marker of distal intestine differentiation. No specific data are available about SATB2 and GATA3 expression in SN-NENs. GATA3, SATB2, and, for comparison, CDX2 expression were investigated in a series of epithelial and non-epithelial SN-NENs. We collected 26 cases of ONB and 7 cases of epithelial SN-NENs diagnosed and treated in our Institution. ONBs were graded according to Hyams' system and epithelial NENs were reclassified into 5 NECs, 1 MiNEN, and 1 amphicrine carcinoma. Immunohistochemistry was performed using standard automated protocols. Hyams' grades 1-3 ONBs stained diffusely and intensely for SATB2, whereas grade 4 ONBs and NECs were globally negative. The non-neuroendocrine component of MiNEN and the amphicrine carcinoma were strongly positive. GATA3 was heterogeneously and unpredictably expressed in Hyams' grades 1-3 ONBs, whereas grade 4 ONBs and NECs were completely negative. CDX2 was negative in all cases. Our study identifies, for the first time, SATB2 and GATA3 expression as features of Hyams' grades 1-3 ONBs, expands the spectrum of SATB2 and GATA3-positive neoplasms, and suggests that Hyams' grade 4 ONBs are not only clinically but also biologically different from low graded ONBs.

Abstract
The urachus is a thick fibrous cord that appears in the fifth month of pregnancy as a result of the allantois obliteration. Urachal cysts occur as a result of a defect in the obliteration of the duct, anomaly detected mainly in children and very rarely in adults. We present three cases of urachal cysts in adults, one of them detected during the study of abdominal pain and the other two, found incidentally during the study of other pathologies. In any case the possibility of urachal cysts was clinically suspected. Histologically, these lesions are lined by epithelium of urothelial type with expression of CK7, CK20, CK5/6, P63 and GATA3. The diagnosis of urachal cysts certainty lies in the histopathological study where the morphology, immunohistochemistry and a proper clinical-pathological correlation, allow to differentiate it from other more frequent abdominal cystic lesions in adults.

Abstract
Objective: To investigate the expression of GATA3, SOX10, and p16 in triple-negative breast cancer (TNBC) and analyze their significance and correlation with clinicopathology. Methods: The expressions of GATA3, SOX10 and p16 in 53 cases of TNBC and 50 cases of non-TNBC were detected by immunohistochemical staining. Results: GATA3 and SOX10 were positive in 58.5%(31/53) and 75.5%(40/53) of TNBC, respectively. The expression of SOX10 was significantly higher than that in non-TNBC (P<0.05). SOX10 was positive in 17 of the 22 cases that lacked GATA3 expression (77.3%). The expression of p16 was significantly higher in the TNBC, and the co-expression with SOX10 was significantly increased (P<0.05). The sensitivity, specificity, and AUC under the ROC curve of SOX10 were higher than those of GATA3. The sensitivity of SOX10 was higher than that of p16, but the specificity was lower than that of p16. The AUC of SOX10 was higher than that of p16. AUC of combined detection of GATA3 and SOX10, SOX10 and p16 were higher than that of each antibody alone (P<0.05). The expression of GATA3, SOX10, and p16 had no significant correlation with age, tumor size, and lymph node metastasis. The expression of SOX10 and p16 in grade 3 and basal-like TNBC increased significantly, and their co-expression increased. Conclusions: The expressions of SOX10 and p16 in TNBC are significantly increased. SOX10 is a reliable marker for the diagnosis of TNBC and a supplement to GATA3. Whether p16 is a marker related to the prognosis of TNBC remains to be further studied.

The study is to investigate the roles of group 2 innate lymphoid cells (ILC2s) in different courses of tuberculosis (TB). Serum and PBMCs were respectively isolated from the TST negative, LTBI (latent TB infection), ATB (active TB) and RTB (recurrent TB) patients. Flow cytometry was used to detect Th1, Th2 and ILC2s in the peripheral blood. The mRNA and protein levels of GATA3, RORα, CRTH2, Hes1, Notch1, NF-κB, and ID2 were detected by qRT-PCR and Western blotting. ILC2 cells from ATB and RTB patients were stimulated with rJagged2 or DAPT in vitro, and co-cultured with CD4+ T cells from TST negative group. ELISA was used to detect cytokine levels. The results showed that compared with the TST negative or LTBI group, Th2 cells and serum IL-4 in ATB group increased dramatically, accompanied by an increase of Th2/Th1 ratio in ATB patients, especially in RTB group. However, ILC2s in the ATB and RTB group increased significantly, along with increased GATA3, RORα, and CRTH2 levels. After rJagged2 stimulation in vitro, the levels of Hes1, Notch1, NF-κB, RORα, GATA3 and ID2 and those of IL-4, IL-5 and IL-13 were significantly increased. These effects were abrogated by DAPT treatment. Then, ILC2s, especially those from RTB patients, induced Th2-type immune response after co-culturing with CD4+ T cells. In conclusion, our results suggest that ILC2s may promote Th2-type immune response in different stages of TB via the Notch-GATA3 pathway.

Abstract
Vascular endothelial growth factor (VEGF) plays a pivotal role in promoting neovascularization. Tumor necrosis factor superfamily 15 (TNFSF15) is an antiangiogenic cytokine prominently produced by endothelial cells in a normal vasculature. In this study, Western blot, quantitative polymerase chain reaction (qPCR), and dual luciferase reporter gene assay were used to validate the mechanisms of TNFSF15-mediated suppression of VEGF production in endothelial cells. We report that TNFSF15 inhibits VEGF production via microRNA-29b (miR-29b) targeting the 3'-UTR of VEGF transcript in mouse endothelial cell line bEnd.3. Neutralizing antibody against TNFSF15, 4-3H, inhibits the level of miR-29b and reinvigorates VEGF. In addition, TNFSF15 activates the JNK signaling pathway as well as the transcription factor GATA3, resulting in enhanced miR-29b production. SP600125, an inhibitor of JNK, eradicates TNFSF15-induced GATA3 expression. Moreover, GATA3 siRNA suppressed TNFSF15-induced miR-29b expression. Together, this study provides evidence and method of activation of the JNK-GATA3 signaling pathway by TNFSF15 that suppresses VEGF gene expression, which gives rise to upregulation of miR-29b.

Abstract
Glycomacropeptide (GMP) is a bioactive peptide derived from milk κ-casein with immune-modulatory and anti-inflammatory properties. Food allergy (FA) is an adverse immune reaction with a broad spectrum of manifestations. Allergen intake induces persistent intestinal inflammation and tissue damage. In this study, the anti-allergic activity of GMP was evaluated using a rat ovalbumin (OVA)-induced FA model with gastrointestinal manifestation. Rats were orally GMP treated from 3 days prior and during FA development. The severity of food anaphylaxis and diarrheal episodes, antibody production and histamine level were measured. Histopathological changes, inflammation and predominant cytokine profile at intestine were analyzed. Oral GMP intake decreased clinical signs and diarrhea severity induced by allergen, with a significant reduction in intestinal edema and expression level of IL-1β and TNF-α. Prophylaxis with GMP also diminished serum anti-OVA IgE and IgG1, and histamine levels. GMP treatment markedly decreased eosinophil infiltration, mast cell and goblet cell hyperplasia, total IgE expression in intestine, and prevented histological changes in villi, crypts and internal muscularis layer. The treatment effectively suppressed IL-5, IL-13 and GATA3 expression and skewed the intestinal cytokine profile toward type 1 and regulatory. These results suggest that GMP may protect against FA through down-regulating the type 2 inflammatory response.

Abstract
Mechanistic studies have improved our understanding of molecular and cellular components involved in asthma and our ability to treat severe patients. An mAb directed against IgE (omalizumab) has become an established add-on therapy for patients with uncontrolled allergic asthma and mAbs specific for IL-5 (reslizumab, mepolizumab), IL-5R (benralizumab), and IL-4R (dupilumab) have been approved as add-on treatments for uncontrolled eosinophilic (type 2) asthma. While these medications have proven highly effective, some patients with severe allergic and/or eosinophilic asthma, as well as most patients with severe non-type-2 disease, have poorly controlled disease. Agents that have recently been evaluated in clinical trials include an antibody directed against thymic stromal lymphopoietin, small molecule antagonists to the chemoattractant receptor-homologous molecule expressed on TH2 cells (CRTH2) and the receptor for stem cell factor on mast cells (KIT), and a DNA enzyme directed at GATA3. Antibodies to IL-33 and its receptor, ST2, are being evaluated in ongoing clinical studies. In addition, a number of antagonists directed against other potential targets are under consideration for future trials, including IL-25, IL-6, TNF-like ligand 1A, CD6, and activated cell adhesion molecule (ALCAM). Clinical data from ongoing and future trials will be important in determining whether these new medications will offer benefits in place of or in addition to existing therapies for asthma.

Abstract
Hypoparathyroidism, sensorineural deafness, and renal dysplasia (HDR) syndrome is a rare autosomal dominant disease caused by GATA3 mutations. Although several cases with variable renal features have been reported, the presence of histological changes within the glomeruli in adult patients is unclear. We herein report an adult case of HDR syndrome with a novel p.C288W (TGC>TGG) missense mutation in GATA3. His renal histology showed a membranoproliferative glomerulonephritis-like glomerular lesion. Additional renal histological analyses of HDR syndrome patients will be needed to clarify the role of GATA3 in both the developing and adult kidney.

Abstract
Vasohibin 2 (VASH2) is identified as an angiogenic factor, and has been implicated in tumor angiogenesis, proliferation and epithelial-mesenchymal transition (EMT). To investigate the EMT role of VASH2 in breast cancer, we overexpressed or knocked down expression of VASH2 in human breast cancer cell lines. We observed that VASH2 induced EMT in vitro and in vivo. The transforming growth factor β1 (TGFβ1) pathway was activated by VASH2, and expression of a dominant negative TGFβ type II receptor could block VASH2-mediated EMT. In clinical breast cancer tissues VASH2 positively correlated with TGFβ1 expression, but negatively correlated with E-cadherin (a marker of EMT) expression. Under hypoxic conditions in vitro or in vivo, we found that down-regulation of estrogen receptor 1 (ESR1) in VASH2 overexpressing ESR1 positive cells suppressed E-cadherin. Correlation coefficient analysis indicated that VASH2 and ESR1 expression were negatively correlated in clinical human breast cancer tissues. Further study revealed that a transcription factor of ESR1, GATA-binding factor 3 (GATA3), was down-regulated by VASH2 under hypoxia or in vivo. These findings suggest that VASH2 drives breast cancer cells to undergo EMT by activation of the TGFβ1 pathway and hypoxia dependent repression GATA3-ESR1 pathway, leading to cancer metastasis.

Abstract
The association of ovarian Brenner tumors and adjacent mucinous tumors is well known but not completely understood. In this study, we analyzed immunohistochemical markers on Brenner tumors and their associated mucinous tumor to explore Mullerian as well as Wolffian and germ cell derivation and determine if the mucinous component is independent or related to the Brenner tumor. Of 32 consecutive cases of Brenner tumors, 8 were identified with significant mucinous component, and 7 additional cases included foci of mucinous epithelium within the Brenner transitional nests. All Brenner tumors were diffusely positive for GATA3 and negative for Paired box gene 8, PAX2, and Sal-like protein 4. Interestingly, the areas of mucinous epithelium as well as mucinous tumors, intermixed and adjacent to the Brenner tumor, were negative for all 4 markers; however, occasional basal-like cells retained expression of GATA3. The immunoprofile of mucinous tumors associated with Brenner tumors shares the lack of Mullerian markers PAX2 and Paired box gene 8 with the Brenner tumor but differs in the expression of GATA3 only in the Brenner tumor component.

Abstract
A novel polysaccharide (LCP50W) with a molecular weight of 4.72 × 10(4) Da was isolated from the pulp tissues of Litchi chinensis . The chemical structure of LCP50W was characterized using physicochemical and instrumental analyses. The results indicated that the main chain of LCP50W consisted of (1→3)-linked β-L-rhamnopyranosyl, (1→6)-linked α-D-glucopyranosyl, and (1→2,6)-linked α-D-glucopyranosyl residues, which branched at O-6. The three branches consisted of (1→2)-linked α-L-rhamnopyranosyl, (1→3)-linked α-D-galactopyranosyl, and (1→3)-linked α-L-mannopyranosyl residues, terminated with (1→)-linked α-L-arabinopyranosyl residues, respectively. The in vitro immunomodulatory assay revealed that LCP50W promoted the proliferation of mouse splenocytes and enhanced the cytotoxicity of NK cells. LCP50W boosted the secretion of Th1 cytokine IFN-γ while it inhibited the secretion of Th2 cytokine IL-4; it also enhanced the expression of T-bet while it inhibited the expression of GATA-3. Additionally, LCP50W promoted the development of cell cycle toward the S phase.

Abstract
Recent advance in mouse genomics has provided us lots of information concerning genes playing critical roles during organogenesis of parathyroid gland. And human counterparts of murine hypoparathyroidism produced by gene manipulation have been identified. Large part of genes which is responsible for hypoparathyroidism consisted from transcription factors such as TBX1, GATA3, SOX3. This may contribute to the abnormalities in the other organogenesis. Systematic survey of the anomalies in face and the other organ is important to confirm the diagnosis. And people should keep in mind that PTH could not be produced only in parathyroid in parathyroid agenesis.

Abstract
High-altitude climate therapy is a well-established therapeutic option, which improves clinical symptoms in asthma. However, little is known about the underlying immunological mechanisms. The study investigates the influence of high-altitude climate therapy on airway inflammation and cellular components of specific and unspecific immune response. Exhaled NO significantly decreased within 3 weeks of therapy in patients with allergic and intrinsic, moderate and severe asthma. Interleukin-10 (IL-10)-secreting peripheral blood mononuclear cells (PBMC) increased within 3 weeks of therapy in six of 11 patients, whereas transforming growth factor-beta(1)-secreting PBMC remained stable. Furthermore, monocyte activation, assessed by CD80 expression significantly decreased during therapy. The frequency of CRTH2-expressing T cells decreased, while regulatory T cells (T(reg)) remained stable. FOXP3 and GATA-3 mRNA expression in CD4(+) T cells did not change, while interferon-gamma and IL-13 mRNA expression decreased in eight of 10 patients. The current data demonstrate that high-altitude climate therapy reduces local airway inflammation. Furthermore, monocytes switch towards a tolerogenic phenotype under high-altitude climate therapy. The T(reg)/Th2 ratio increases; however, because of the absence of antigens/allergens, no de novo differentiation of Th2 nor T(reg) cells is observed. The high-altitude climate therapy therefore may form the immunological basis for the endogenous control of allergen-driven diseases.

Abstract
Despite the radical surgical resection performed in patients with colorectal carcinoma, there is a high rate of tumor recurrence. Over an observation period of 3 years, 18% of the patients in our collective suffered a tumor relapse with local or distinct metastases after initial R0-resection. Some evidence suggests that this may be due to suppression of anti-tumor responses, a phenomenon that might be attributed to regulatory T cells. The aim of our study was to investigate the tumor-specific immune response depending on the UICC stage of patients with colorectal cancer. The cellular immune responses against defined antigens that are overexpressed in most of the patients with colorectal cancer were characterized. For this purpose, the tumor suppressor gene, p53, was chosen as the tumor-associated antigen that exhibits mutations and overexpression in up to 60% of colorectal carcinoma. We observed that p53 induced both IFN-gamma and IL-10 secretion. The predominance of IL-10 production indicated that regulatory T cells directly participate in modulating the anti-tumor immune response. IL-10 levels in the blood as well as the expression of regulatory T-cell specific genes at the tumor site correlate with the UICC stage of the disease. These results may provide an explanation for the poor prognosis and increased recurrence rate in patients with advanced carcinoma.

Abstract
T cell receptor (TCR) signaling plays an important role in early interleukin (IL)-4 production by naive CD4+ T cells. This “antigen-stimulated” early IL-4 is sufficient for in vitro Th2 differentiation. Here, we provide evidence that early IL-4 production by naive CD4+ T cells stimulated with cognate peptide requires TCR-induced early GATA-3 expression and IL-2 receptor signaling, both of which are controlled by the degree of activation of extracellular signal-regulated kinase (ERK). Stimulation of naive CD4+ T cells from TCR transgenic mice with low concentrations of peptide-induced IL-2–dependent STAT5 phosphorylation, IL-4-independent early GATA-3 expression, and IL-4 production. Neutralization of IL-2 abolished early IL-4 production without affecting early GATA-3 expression. In addition, naive CD4+ T cells from GATA-3 conditional KO mice failed to produce early IL-4 in response to TCR/CD28 stimulation. Stimulation with high concentrations of peptide abrogated early GATA-3 expression and IL-2–dependent STAT5 phosphorylation, and resulted in the failure to produce early IL-4. This high concentration–mediated suppression of early IL-4 production was reversed by blockade of the ERK pathway. A MEK inhibition rescued early GATA-3 expression and responsiveness to IL-2; these cells were now capable of producing early IL-4 and undergoing subsequent Th2 differentiation.

Abstract
Upon activation in vitro, only a fraction of the bulk human T helper cell cultures secret the hallmark Th1/2 cytokines (IFN-gamma for Th1 and IL-4 for Th2, respectively). It is uncertain whether these IFN-gamma-/IL-4- cells are differentiated Th1 or Th2 cells. Here, we have characterized live IFN-gamma+, IL-4+ and IFN-gamma-/IL-4- cells isolated from Th cell cultures treated under Th1 or Th2 polarizing conditions by employing affinity matrix capture technology. RNA samples from the sorted cells were analyzed by real time RT-PCR and microarrays. The double negative cells from either Th1 or Th2 cultures expressed lower levels of Th1/Th2 marker cytokine genes (IFNgamma, IL4, and IL5). However, they were comparable with the IFN-gamma+ or IL-4+ cells in the expression levels of other Th1/Th2 marker genes (GATA3, Tbet, and IL12Rbeta2). Most importantly, these double negative cells were already committed in their Th1/Th2 lineages. Gene expression profiling analysis showed that very few previously identified Th1/Th2 marker genes were differentially expressed between the IFN-gamma or IL-4 producers and the non-producers, further underscoring the similarity between these two groups.

Abstract
This study was designed to investigate the effects of allitridin on the expression of transcription factors T-bet and GATA-3 in mice infected by murine cytomegalovirus (MCMV). A BALB/c mouse model system of MCMV infection was established. Twenty mice were allocated randomly into an allitridin-treated group (n = 10) and a placebo control group (n = 10). The same dose (25 mg/kg/day) and regimen of allitridin were used in the treated group in the 24 hours after virus infection; the same volume of saline solution was injected in placebo control mice. In an additional blank control group (n = 10), the same volume of saline solution was injected. The expression levels of the transcription factors T-bet and GATA-3 were measured by reverse transcription-polymerase chain reaction. The expression levels of the T helper (Th) 1 cytokine interferon-gamma (IFN-gamma) and the Th2 cytokine interleukin (IL)-10 in supernatant of spleen cell culture were measured by enzyme-linked immunosorbent assay. MCMV infection markedly down-modulated the expression of IFN-gamma and T-bet and significantly up-modulated the expression of IL-10 and GATA-3. Allitridin induced significantly (P < .01) increased expression of the transcription factor T-bet and the Th1 cytokine IFN-gamma and markedly (P < .01) decreased expression of the transcription factor GATA-3 and the Th2 cytokine IL-10. Thus MCMV infection could lead to disequilibrium of Th1/Th2 cytokine expression: The level of the Th1 cytokine IFN-gamma was decreased significantly, and Th2 cytokine IL-10 was overexpressed markedly. Allitridin could up-regulate the expression of T-bet and IFN-gamma and inhibit the expression of GATA-3 and IL-10 in MCMV-infected mice, indicating a Th1 dominant state, which should enhance the specific cellular immune reactions against cytomegalovirus (CMV) and be helpful for clearance of CMV from the host.

Abstract
CC chemokine receptor 5 (CCR5) is the major HIV-1 coreceptor and its expression levels are a critical determinant of HIV-1 infection. However, the molecular mechanisms of CCR5 regulation in primary targets of HIV-1 remain unknown. Despite binding to conserved DNA elements, we show that the transcription factors GATA binding protein 1 (GATA-1) and GATA-3 differentially suppress the expression of CCR5 in stem-cell-derived dendritic cells and primary human T-cell subsets. In addition, GATA-1 expression was also more potent than GATA-3 in suppressing T helper 1 (Th1)-associated genes, interferon-gamma (IFNgamma), and CXC chemokine receptor-3 (CXCR3). GATA-1, but not GATA-3, potently suppressed CCR5 transcription, thereby rendering human T cells resistant to CCR5-tropic HIV-1 infection. However, GATA-1 could also serve as a surrogate for GATA-3 in its canonic role of programming Th2 gene expression. These findings provide insight into GATA-3-mediated gene regulation during T-cell differentiation. Importantly, decoding the mechanisms of GATA-1-mediated repression of CCR5 may offer an opportunity to develop novel approaches to inhibit CCR5 expression in T cells.

Abstract
Primary T helper 2 cells are heterogeneous, expressing subsets of cytokines at varying levels. Mechanisms controlling this spectrum of phenotypes are still unclear. The ETS family transcription factor PU.1 is expressed in Th2 but not Th1 cells. Th2 cytokine production is decreased in cultures transduced with a PU.1-expressing retrovirus and increased in Th2 cells following RNAi that decreases PU.1 expression. In primary cultures, PU.1 expression is restricted to a subpopulation of Th2 cells that express CCL22 and a subset of Th2 cytokines. PU.1 regulates the Th2 phenotype by interfering with GATA-3 DNA binding without altering GATA-3 protein levels. Thus, the expression of PU.1 in subsets of Th2 cells establishes a defined cytokine profile and contributes towards establishing the spectrum of cytokine production observed in Th2 populations.

Abstract
BACKGROUND We previously showed that a positive impact of peritoneal defense response on the outcome of peritoneal dialysis (PD)-related peritonitis is characterized by an increased pattern of peritoneal CD4/CD8 T-cell ratio with a predominant CD4(+)-T helper subtype 1 phenotype. To further explore longitudinal changes in peritoneal immunity during PD-related peritonitis, we examined the production of interleukin 12 (IL-12), IL-18, and interferon gamma (IFN-gamma) in peritoneal dialysate effluent (PDE) and kinetic expression of the transcription factors T box expressed in T cells (T-bet) and guanine adenine thymine adenine (GATA) binding protein 3 (GATA-3) in peritoneal T cells during peritonitis. Correlations between these observations and responses to antibiotics were analyzed. METHODS IL-12, IL-18, and IFN-gamma protein and IFN-gamma, T-bet, and GATA-3 messenger RNA (mRNA) were measured in PDE during various phases of peritonitis in 40 patients undergoing PD. Patients were divided into 2 groups according to whether they had a rapid versus delayed response to antibiotic treatment. RESULTS In the early phase of peritonitis, IL-12, IL-18, and IFN-gamma levels in PDE were significantly greater in the rapid-response group (P < 0.05). Changes in peritoneal IL-12 and IL-18 levels preceded changes in IFN-gamma levels. The kinetics of IFN-gamma, T-bet, and GATA-3 mRNA expression in peritoneal T cells, measured by means of real-time polymerase chain reaction, differed between the 2 groups. In the rapid-response group, IFN-gamma and T-bet mRNA expression increased, whereas that of GATA-3 decreased over time. Results were opposite in the delayed-response group, with IFN-gamma and T-bet levels decreasing and GATA-3 levels increasing over time. CONCLUSION These data suggest that local IL-12 and IL-18 production is part of a protective early immune response to PD-related peritonitis. High IL-12 and IL-18 levels in PDE during the early phase of peritonitis correlated with a predominant type 1 immune response and favorable outcome.

Abstract
Administration of bee venom (BV) elicits anti-inflammatory, anti-nociceptive and anti-allergic effects in various animal models. This study was designed to evaluate the direct effects of BV on helper T cell activities and on Th1/Th2 lineage development using both in vitro and in vivo conditions. In the Th1 skewed condition, BV increased the expression of IFN-gamma mRNA and enhanced the expression of T-bet on purified CD4(+) T cells from splenocytes of BALB/c mice. On the other hand, BV treatment did not alter the expression of IL-4 or GATA-3 in a Th2 driven environment. To elucidate the effects of BV on Th1/Th2 lineage development under in vivo conditions, BV was given by intraperitonial injection to BALB/c mice. It significantly increased the CD4(+) T cell population and enhanced IFN-gamma expression, while IL-4 transcripts were not altered upon in vivo activation using an anti-CD3 antibody injection. Taken together, these results imply that BV induces Th1 lineage development from CD4(+) T cells by increasing the expression of a Th1-specific cytokine, IFN-gamma. In addition, this result may be mediated by inducing a Th1-specific transcription factor, T-bet.

Abstract
AIMS/HYPOTHESIS Type 1 diabetes is the result of an inflammatory T helper 1 (Th1) lymphocyte-mediated beta cell destructive process. The majority of diabetes-prone BioBreeding (BBdp) rats fed wheat protein-based diets, such as NTP-2000, develop type 1 diabetes and display a mild coeliac-like enteropathy. Mesenteric lymph nodes (MLNs), which drain the gut, are the major inductive site where dietary antigens are recognised in the gut-associated lymphoid tissue (GALT). We hypothesised that this compartment could be a site of abnormal wheat protein-induced Th1 cell activation. METHODS MLN cells were isolated from BBdp and BB control (BBc) rats that were fed NTP-2000 or a hydrolysed casein (HC)-based diet at ages that pre-date classic insulitis. The inflammatory status, phenotype and proliferation of these cells in response to wheat protein were determined. RESULTS The expression ratio of T-bet : Gata3, master transcription factors for Th1 and Th2 cytokines, was increased in the MLN from NTP-2000-fed BBdp rats compared with that from BBc rats, mainly due to decreased Gata3 expression. CD3(+)CD4(+)IFN-gamma(+) T cells were more prevalent in the MLN of wheat-fed BBdp rats, but remained at control levels in BBdp rats fed a diabetes-retardant HC diet. BBdp MLN cells proliferated in response to wheat protein antigens in a specific, dose-dependent manner, and >93% of cells were CD3(+)CD4(+) T cells. This proliferation was associated with a low proportion of CD4(+)CD25(+) T cells and a high proportion of dendritic cells in the MLN of BBdp rats. CONCLUSIONS/INTERPRETATION Before insulitis is established, the MLNs of wheat-fed BBdp rats contain an unusually high proportion of Th1 cells that proliferate specifically in response to wheat protein antigens.

Abstract
The transcription factor GATA-3 is one regulator of Th1/Th2 differentiation. In sheep, we recently discovered a putative GATA-binding site (WGATAR) in the second intron of the Th1-cytokine gene interleukin 2 (IL2), showing a single nucleotide polymorphism (G/C). As genetic variations in cytokine genes are thought to regulate cytokine production, we studied the significance of this polymorphism for IL2 transcription. Sheep with different IL2 genotypes were identified by single-strand conformation polymorphism (SSCP)-analysis and IL2 transcription levels in peripheral blood mononuclear cells (PBMC) isolated from these animals were compared. For this purpose, transcription of IL2 mRNA was quantified by real-time polymerase chain reaction in unstimulated PBMC and in PBMC incubated for 4h in the presence of concanavalin A (ConA) or phorbol 12-myristate 13-acetate plus ionomycin (PMA/I). Compared to unstimulated cells, stimulation with ConA and PMA/I increased the IL2 mRNA transcription in average by 300- and 20-fold, respectively. Nevertheless, no significant differences in IL2 transcription between the genotypes could be detected. These findings were confirmed by band shift studies using different oligonucleotides containing variations of the potential binding motif, which showed no differences in the gel mobility after incubation with nuclear extract containing GATA-3. The obtained results argue against an impact of this polymorphism on the IL2 transcription and the genetic disease resistance in sheep.

Abstract
The auditory neuroblast cell line US/VOT-N33 (N33), which is conditionally immortal, was studied as an in vitro model for the differentiation of spiral ganglion neurons (SGNs) and as a candidate for cell transplantation in rodents. It expresses numerous molecular markers characteristic of auditory neuroblasts, including the transcription factors GATA3, NeuroD, Brn3a and Islet1, as well as the neuronal cytoskeletal protein beta3-tubulin. It displays active migratory behaviour in vitro and in vivo. In the presence of the fibroblast growth factors FGF1 or FGF2 it differentiates bipolar morphologies similar to those of native SGNs. In coculture with neonatal cochlear tissue it is repelled from epithelial surfaces but not from native SGNs, alongside which it extends parallel neuronal processes. When injected into the retina in vivo, EGFP-labelled N33 cells were traced for 1-2 weeks and migrated rapidly within the subretinal space. Cells that found their way into the retinal ganglion cell layer extended multiple processes but did not express beta3-tubulin. The ability of N33 to migrate, to differentiate, to localize with native SGNs in vitro and to survive in vivo suggests that they provide an effective model for SGN differentiation and for cell transplantation into the ear.

Recently, a member of the GATA-binding family of transcription factors was shown to be involved in human hypoparathyroidism, sensorineural deafness, and renal abnormality (HDR) syndrome. We report here a Japanese family in which two of the members are affected with HDR syndrome. Sequence analysis of GATA3 showed a heterozygous novel mutation in this family: an unusual mutation at exon 3 (709insC) resulting in a premature stop at codon 302 with a loss of both of the zinc finger domains.

Abstract
Experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis, is a Th1-mediated inflammatory demyelinating disease of the CNS. AMP-activated protein kinase was reported recently to have anti-inflammatory activities by negatively regulating NF-kappaB signaling. In this study, we investigated the prophylactic and therapeutic efficacy of an AMP-activated protein kinase activator, 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR), in active and passive EAE induced by active immunization with PLP(139-151) or MOG(35-55) and in adoptive transfer of PLP(139-151)-sensitized T cells, respectively. In vivo treatment with AICAR exerted both prophylactic and therapeutic effects on EAE, attenuating the severity of clinical disease. The anti-inflammatory effects of AICAR were associated with the inhibition of the Ag-specific recall responses and inhibition of the Th1-type cytokines IFN-gamma and TNF-alpha, whereas it induced the production of Th2 cytokines IL-4 and IL-10. Treatment of PLP(139-151)-specific T cells in vitro with AICAR decreased their expression of T-bet in response to IL-12, a Th1 transcription factor, whereas in response to IL-4, it induced the expression and phosphorylation of Th2 transcription factors GATA3 and STAT6, respectively. Moreover, treatment of APCs in vitro with AICAR inhibited their capability to present the proteolipid protein peptide to PLP(139-151)-specific T cells. In an irrelevant Th1-mediated, OT-2 TCR transgenic mouse model, AICAR impaired in vivo Ag-specific expansion of CD4(+) T cells. Together, these findings show for the first time that AICAR is a novel immunomodulator with promising beneficial effects for the treatment of multiple sclerosis and other Th1-mediated inflammatory diseases.

Abstract
CD8(+) T cells play an important role in the induction of the autoimmune response in non-obese diabetic (NOD) mice. Here we describe abnormalities in the control of cytokine production by NOD CD8(+) T cells. NOD CD8(+) T cells had an increased propensity to produce IFN-gamma upon TCR activation, in both adult and 2-week-old mice. NOD CD8(+) T cells had a reduced capacity to produce IL-4 in type 2 conditions compared to CD8(+) T cells from the diabetes-resistant strains BALB/c and C57BL/6. Both GATA-3 and c-Maf, two positive transactivators for IL-4 gene expression, were expressed in type 2 conditions at comparable levels in NOD CD8(+) T cells. The GATA-3 was functional since normal levels of IL-5 were produced and the IL-4 promoter was hyperacetylated in NOD CD8(+) T cells. In contrast, c-Maf failed to bind to its responsive element as determined by chromatin immunoprecipitation (ChIP) assay. These results suggest that NOD CD8(+) T cells possess an increased propensity to produce IFN-gamma and impaired c-Maf-dependent DNA binding activities in vivo that lead to reduced IL-4 production following TCR activation. These defects may facilitate the development of the autoimmune response by inducing an overall type 1-biased immune response in NOD mice.

Abstract
Differentiation of naive CD4 T cells into Th2 cells requires protein expression of GATA3. Interleukin-4 induces STAT6 activation and subsequent GATA3 transcription. Little is known, however, on how T cell receptor-mediated signaling regulates GATA3 and Th2 cell differentiation. Here we demonstrated that T cell receptor-mediated activation of the Ras-ERK MAPK cascade stabilizes GATA3 protein in developing Th2 cells through the inhibition of the ubiquitin-proteasome pathway. Mdm2 was associated with GATA3 and induced ubiquitination on GATA3, suggesting its role as a ubiquitin-protein isopeptide ligase for GATA3 ubiquitination. Thus, the Ras-ERK MAPK cascade controls GATA3 protein stability by a post-transcriptional mechanism and facilitates GATA3-mediated chromatin remodeling at Th2 cytokine gene loci leading to successful Th2 cell differentiation.

Abstract
BACKGROUND Expression of estrogen receptor-alpha (ERalpha) as determined by immunohistochemistry of tumor tissue is currently the most clinically useful test to predict hormone responsiveness of breast cancer. Thirty percent of ERalpha-positive breast cancers do not respond to hormonal therapy. GATA-3 is a transcription factor that is expressed in association with ERalpha and there is evidence that GATA factors influence response to estrogen. In this pilot study, we investigated whether GATA-3 expression is associated with hormone response in breast cancer. STUDY DESIGN Breast cancer tissue was stained for GATA-3 expression by immunohistochemistry in ERalpha-positive cancers from 28 patients, 14 of whom were defined as hormone unresponsive (cases) and 14 of whom were age-matched controls with hormone-responsive, ERalpha-positive cancers (controls). RESULTS Comparing cases and controls, there were no differences in expression of ERalpha; progesterone receptor, ErbB2; or tumor grade. Using 20% nuclear staining to characterize tumors as GATA-3 positive or GATA-3 negative, 6 of 14 (43%) cancers in the hormone-unresponsive group and none of the controls were classified as GATA-3 negative (odds ratio, 8.2; 95% confidence interval, 1.2-infinity; p = 0.031). Using different cut points to characterize GATA-3 positivity yielded very similar results, indicating a positive association between lack of GATA-3 expression and lack of response to hormonal therapy. CONCLUSIONS The study suggests that analyzing ERalpha-positive breast tumors for GATA-3 using immunohistochemistry might improve prediction of hormone responsiveness. The association between GATA-3 expression and hormone response suggests that GATA-3 may play a role in mechanisms controlling response to estrogen.

Abstract
T-bet (T-box expressed in T cells) and GATA-3 are transcription factors that play a critical role in the development of Th1 and Th2 cells, as do genes of the SOCS (suppressor of cytokine signaling) family, albeit indirectly. Another transcription factor, Foxp3, is a master regulator of natural regulatory T cells (Tregs). To identify the role of these factors in impaired Th1 responses of patent filarial infection, analysis of cytokine, SOCS, and transcription factor mRNA expression was performed on purified T cells of filaria-infected individuals (n = 6) and uninfected controls (n = 6). As expected (and in contrast to cells of uninfected individuals), there was a significant depression of gamma interferon (IFN-gamma) and a concomitant increase in interleukin-4 (IL-4), IL-5, and IL-10 mRNA expression following stimulation with parasite antigen (BmA) but not with a polyclonal T-cell (anti-CD3) stimulus. T-bet (but not GATA-3) was expressed at significantly lower levels in cells of filaria-infected individuals in response to BmA compared with those from the uninfected group, accounting, at least partially, for the diminished IFN-gamma expression. Second, we found no significant differences in expression of Foxp3 between the two groups, although induction of Foxp3 expression correlated with induced expression levels of IL-10, implicating Tregs in the IL-10 expression seen. Finally, parasite-specific T-cell expression of SOCS-1, SOCS-5, and SOCS-7 was significantly diminished among infected patients; in contrast, expression of SOCS-3 increased. Our data therefore indicate that the impaired Th1 responses observed in patent lymphatic filariasis are associated with decreased expression of T-bet, SOCS-1, SOCS-5, and SOCS-7 and increased expression of SOCS-3 in T cells.

Abstract
Naive T helper (Th) lymphocytes are induced to express the il4 (interleukin-4) gene by simultaneous signaling through the T cell receptor and the interleukin (IL)-4 receptor. Upon restimulation with antigen, such preactivated Th lymphocytes can reexpress the il4 gene independent of IL-4 receptor signaling. This memory for expression of the il4 gene depends on epigenetic modification of the il4 gene locus and an increased expression of GATA-3, the key transcription factor for Th2 differentiation. Here, we have identified a phylogenetically conserved sequence, the conserved intronic regulatory element, in the first intron of the il4 gene containing a tandem GATA-3 binding site. We show that GATA-3 binds to this sequence in a position- and orientation-dependent manner, in vitro and in vivo. DNA demethylation and histone acetylation of this region occurs early and selectively in differentiating, IL-4-secreting Th2 lymphocytes. Deletion of the conserved element by replacement of the first exon and part of the first intron of the il4 gene with gfp leads to a defect in the establishment of memory for expression of IL-4, in that reexpression of IL-4 still requires costimulation by exogenous IL-4. The conserved intronic regulatory element thus links the initial epigenetic modification of the il4 gene to GATA-3 and serves as a genetic control element for memory expression of IL-4.

Abstract
BACKGROUND Helper T cells and T cell cytokines play central roles in allergic disorders including bronchial asthma. We reported enhanced IL-5 production by peripheral blood T cells of asthmatic patients. A transcription factor, GATA-3, has been implicated in IL-5 gene expression. This study was undertaken to clarify the role of GATA-3 in the upregulation of IL-5 synthesis in asthmatic patients. METHOD Peripheral CD4+ T cells were transfected with an IL-5 promoter reporter construct as well as its mutants in the presence or absence of a GATA-3 expression vector. Messenger RNA expression level of GATA-3 in CD4+ T cells of asthmatic subjects was compared to that of healthy donors. RESULTS IL-5 promoter activity in CD4+ T cells was enhanced by overexpression of GATA-3, whereas it was diminished by the introduction of mutations in the putative GATA-3 binding sites. The GATA-3 expression level in CD4+ T cells of asthmatic patients was equivalent to that of healthy controls. CONCLUSION The expression level of GATA-3 may not be an essential factor to cause IL-5 hyperproduction in bronchial asthma, though GATA-3 is crucially involved in IL-5 gene transcription in human peripheral CD4+ T cells.

Abstract
Infection of ruminants with Mycobacterium avium subspecies paratuberculosis (M. paratuberculosis) leads to a chronic and often fatal granulomatous enteritis known as Johne's disease. Most infections with M. paratuberculosis occur during the first 6 months of life, and there is some evidence for transmission in utero. Once established, infections typically exist in a subclinical state for several years. Recent gene-expression profiling studies suggested the hypothesis that inherent gene-expression profiles in peripheral blood mononuclear cells (PBMCs) from M. paratuberculosis-infected cattle may be different than expression profiles in PBMCs from uninfected controls. If true, this would suggest that it is possible to identify an M. paratuberculosis infection "signature" through transcriptional profiling of peripheral immune cells. In addition, identification of groups or classes of genes showing inherently different expression in PBMCs from M. paratuberculosis-infected cattle relative to PBMCs from uninfected controls might highlight important interactions between this pathogen and the host immune system. In this report, we describe studies aimed at testing this hypothesis. Our novel results indicate that, indeed expression profiles of at least 42 genes are inherently different in freshly isolated PBMCs from M. paratuberculosis-infected cattle when compared to similar cells from uninfected controls. Gene-expression differences observed following microarray analysis were verified and expanded upon by quantitative real-time PCR (Q-RT-PCR). Our results indicate that T cells within PBMCs from M. paratuberculosis-infected cows have adopted a predominant Th 2-like phenotype (enhanced expression of IL-5, GATA 3, and possibly IL-4 mRNA), that cells within infected cow PBMCs may exhibit tissue remodeling deficiencies through higher expression of tissue inhibitor of matrix metalloproteinase (TIMP) 1 and TIMP2 RNA and lower expression of matrix metalloproteinase (MMP) 14 RNA than similar cells from healthy controls, and that cells within the PBMC population of M. paratuberculosis-infected cows are likely poised for rapid apoptosis (upregulation of CIDE-A, Bad, TNFRI, and Fas).

Abstract
Peroxisome proliferator-activated receptor-gamma (PPARgamma) plays a role in adipocyte differentiation and insulin sensitization. We identified and characterized a new C/T substitution at position -689 (-689C>T) in the P2 promoter of PPARgamma in a putative GATA binding site. By electrophoretic mobility shift assay, both GATA2 and GATA3 proteins could bind weakly to the wild-type P2 -689 GATA binding site but not to the mutated site. Neither GATA2 nor GATA3 was able to regulate significantly the P2 promoter activity in a reporter-luciferase assay, whatever the allele at position -689 was, suggesting that the -689 putative GATA site was probably not a functional target for GATAs. However, the presence of the -689T allele rendered the P2 promoter less active at the basal state. We genotyped a population of 1155 men and women for the -689C>T polymorphism and looked for possible associations with anthropometric and lipid variables. The carriers of the -689T allele had elevated body weight and LDL-cholesterol concentrations compared with the homozygous for the common allele. Haplotype analyses including the -681C>G (P3 promoter), -689C>T (P2 promoter), and Pro12Ala (exon B) polymorphisms were performed. Carriers of the G-T-Ala haplotype (corresponding to the P3 -681C>G, P2 -689C>T and Pro12Ala polymorphisms in this order) had elevated LDL-cholesterol concentrations and body weight compared with C-C-Pro individuals. In conclusion, we identified a new polymorphism in the P2 promoter of PPARgamma. The P3 -681C>G, P2 -689C>T, and Pro12Ala polymorphisms and related haplotypes were associated with higher body weight and plasma LDL-cholesterol concentrations.
