Background: Barakat syndrome is a rare autosomal dominant disorder characterized by hypoparathyroidism, sensorineural deafness, and renal disease, collectively known as HDR syndrome. This disease is caused by the mutation of GATA3 gene located on chromosome 10p15. GATA3 is involved in the embryonic development of kidneys, inner ears, parathyroid glands, and central nervous systems.Case report: ...

Forkhead box protein A1 (FOXA1) is essential for the growth and differentiation of breast epithelium, and has a favorable outcome in breast cancer (BC). Elevated FOXA1 expression in BC also facilitates hormone responsiveness in estrogen receptor (ESR)-positive BC. However, the interaction between these two pathways is not fully understood. FOXA1 and GATA binding protein 3 (GATA3) along with ESR...

The transcription factor GATA-3 is essential for early T cell development and differentiation of naive CD4(+) T cells into Th2 effector cells. To study the function of GATA-3 during T cell-mediated immune responses in vivo, we investigated CD2-GATA3-transgenic mice in which GATA-3 expression is driven by the CD2 locus control region. Both in the CD4(+) and the CD8(+) T cell population the propo...

BACKGROUND The pathologic distinction between high-grade prostate adenocarcinoma (PAC) involving the urinary bladder and high-grade urothelial carcinoma (UC) infiltrating the prostate can be difficult. However, making this distinction is clinically important because of the different treatment modalities for these two entities. METHODS A total of 249 patient cases (PAC, 111 cases; UC, 138 case...

Effective immune responses to pathogens require the activation and differentiation of both innate and adaptive lymphocytes, such as innate lymphoid cells (ILCs) and T cells, respectively. ILCs consist of distinct helper-like subsets representing innate versions of CD4 + T helper subsets, whereas natural killer cells represent the innate counterpart of CD8 + cytotoxic T cells. By producing effec...

Regulatory T (Treg) cells can express the transcription factors T-bet and GATA3 but the function of this expression and whether such cells represent stable subsets is still unknown. By using multiple reporter tools, we show that the expression of T-bet and GATA3 in Treg cells is dynamically influenced by the cytokine environment. Treg cell-specific deletion of either Tbx21 or Gata3 genes singly...

Hypoparathyroidism, deafness, and renal dysplasia (HDR; OMIM 146255) syndrome is a rare disease, inherited dominantly and found to be related with GATA3 (GATA binding protein 3) gene mutations. A 13-year and 8-month-old boy who presented with hypocalcemia was diagnosed with hypoparathyroidism. He also had dysmorphic facial features, renal anomaly (pelvic kidney), and mild sensorineural hearing ...

The pathophysiological function of the forkhead transcription factor FOXN3 remains to be explored. Here we report that FOXN3 is a transcriptional repressor that is physically associated with the SIN3A repressor complex in estrogen receptor-positive (ER+) cells. RNA immunoprecipitation-coupled high-throughput sequencing identified that NEAT1, an estrogen-inducible long noncoding RNA, is required...

Paclitaxel is a first-line microtubule-stabilizing drug in treating prostate cancer. However, most patients develop resistance and experience relapse. Morin (3,5,7,20,40-pentahydroxyflavone) is an anti-tumor flavonoid in a numerous types of cancer cells including breast, ovarian and lung cancers. We therefore researched the effects of morin as an adjuvant to paclitaxel in in treating DU145 and ...

We have recently described the presence of the erythropoietin receptor (EPO-R) on CD4(+) lymphocytes and demonstrated that its expression increases during their activation, reaching a level reported to be typical for erythroid progenitors. This observation suggests that EPO-R expression is modulated during lymphocyte activation, which may be important for the cells' function. Here we investigat...
