During development, generation of neurons is coordinated by the sequential activation of gene expression programs by stage- and subtype-specific transcription factor networks. The SoxC group transcription factors, Sox4 and Sox11, have recently emerged as critical components of this network. Initially identified as survival and differentiation factors for neural precursors, SoxC factors have now been linked to a broader array of developmental processes including neuronal subtype specification, migration, dendritogenesis and establishment of neuronal projections, and are now being employed in experimental strategies for neuronal replacement and axonal regeneration in the diseased central nervous system...

CITED2 (CBP/p300-interacting-transactivator-with-an-ED-rich-tail 2) is a regulator of the acetyltransferase CBP/p300 and elevated CITED2 levels are shown in a number of acute myeloid leukemia (AML). To study the in vivo role of CITED2 in AML maintenance, AML cells were transduced with a lentiviral construct for RNAi-mediated knockdown of CITED2. Mice transplanted with CITED2-knockdown AML cells (n=4) had a significantly longer survival compared to mice transplanted with control AML cells (P<0.02). In vitro, the reduction of CITED2 resulted in increased p53-mediated apoptosis and CDKN1A expression, whereas BCL2 levels were reduced...

Bronchopulmonary dysplasia (BPD) is currently the most common severe complication in premature infants and is characterized by the arrest of alveolar and vascular growth. Alveolar type II cells play an important role in the pathological foundation of BPD. An association of BPD with epithelial‑to‑mesenchymal transition (EMT) in type II cells exposed to hyperoxia was previously identified. SOX4, a transcription factor that is indispensable to embryogenesis, including lung development, participates in regulating EMT and cell survival, affecting tumorigenesis...

The SOX4 transcription factor is involved in various cellular processes, such as embryonic development and differentiation. Deregulated expression of Sox4 in several human cancers has been reported to date, but its biological functions in the progression of osteosarcoma remain unclear. In this study, we found that the expression levels of SOX4 protein were significantly higher in high-grade osteosarcoma tissues and metastatic osteosarcoma tissues. Its overexpression was associated with poor prognosis in osteosarcoma...

BACKGROUND AND AIMS: The enteric nervous system (ENS) regulates gastrointestinal function via different subtypes of neurons, organized into fine-tuned neural circuits. It is not clear how cell diversity is created within the embryonic ENS-information required for development of cell-based therapies and models of enteric neuropathies. We aimed to identify proteins that regulate ENS differentiation and network formation. METHODS: We generated and compared RNA expression profiles of the entire ENS, ENS progenitor cells, and non-ENS gut cells of mice, collected at embryonic days 11...

BACKGROUND: Colon cancer-associated transcript-1 (CCAT1) has been demonstrated to act as an oncogene and promote chemoresistance in several cancers. However, little is known about the underlying mechanism of CCAT1 in cisplatin (DDP) resistance of non-small-cell lung cancer (NSCLC) cells. METHODS: qRT-PCR was performed to detect the expression levels of CCAT, miR-130a-3p, or sex-determining region Y-box 4 (SOX4) mRNA. Luciferase reporter assay, RNA immunoprecipitation (RIP), and qRT-PCR analysis were carried out to explore the potential targets of CCAT1 or miR-130a-3p...

Aberrant expression of microRNAs (miRs) serves essential roles in the generation and progression of various types of human cancer. In the present study, the expression and biological functions of miR-381 in human gastric carcinoma (GC) were focused upon. The results of reverse transcription-quantitative polymerase chain reaction analysis revealed that the expression of miR-381 was significantly downregulated in GC tissue samples. Furthermore, low expression of miR-381 was identified to be associated with lymphatic metastasis and advanced tumor-node-metastasis stage (III+IV)...

The GIFT (Genetically Improved Farmed Tilapia) tilapia, Oreochromis niloticus, is cultured widely for the production of freshwater fish in China. Streptococcosis, which is related to pathogenic infections, occurs frequently in juvenile and adult female GIFT individuals. Resveratrol (RES) has been used in feed to control these infections in freshwater tilapia. To address the effects of RES on tilapia, we used high-throughput RNA sequencing technology (RNA-Seq, HiSeq. 2500) to explore the global transcriptomic response and specific involvement of hepatic mRNA of juvenile O...

MicroRNAs (miRNAs) are small, non-coding RNAs which can serve as oncogenes or tumor suppressor genes in human cancers. Herein, the transcriptomic differences of miRNAs in ccRCC were globally assessed using publicly available microarray dataset (GSE71302) from Gene Expression Omnibus (GEO) and we identified miR-138 as a potential onco-suppressive miRNA. We further found that the expression of miR-138 was dramatically decreased in ccRCC cell lines and clinical ccRCC tissue samples, and the low miR-138 expression was closely correlated with tumor progression and prognosis in ccRCC patients...

Glaucoma and other optic neuropathies result in optic nerve degeneration and the loss of retinal ganglion cells (RGCs) through complex signaling pathways. Although the mechanisms that regulate RGC development remain unclear, uncovering novel developmental pathways may support new strategies to regenerate the optic nerve or replace RGCs. Here we review recent studies that provide strong evidence that the Sry-related high-mobility-group C (SoxC) subfamily of transcription factors (TFs) are necessary and sufficient for axon guidance and RGC fate specification...

The SOX4 transcription factor is a key regulator of embryonic development, cell-fate decision, cellular differentiation and oncogenesis. Abnormal expression of SOX4 is related to malignant tumor transformation and cancer metastasis. However, no reports are available regarding the clinical significance of SOX4 in acute myeloid leukemia (AML) and the role of SOX4 in leukemogenesis. In the current study, we found that AML patients with low bone marrow (BM) SOX4 expression had higher remission rates and longer overall survival than those with high SOX4 expression, regardless of age, white blood cell count at diagnosis, karyotype profile and NPM1/FLT3-ITD status...

Anaplastic lymphoma kinase (ALK), which is a receptor tyrosine kinase, is essentially and transiently expressed in the developing nervous system. Here we examined the functional role of the ALK gene in glioblastomas (GBMs). In clinical samples of GBMs, high ALK expression without gene rearrangements or mutations was frequently observed in perivascular lesions, in contrast to the relatively low expression in the perinecrotic areas, which was positively correlated with N-myc and phosphorylated (p) Stat3 scores and Ki-67 labeling indices...

Increasing evidence has revealed that aberrant expression of miRNAs contributes to non-small cell lung cancer (NSCLC) development and progression. However, the roles and mechanisms of various miRNAs in NSCLC remain to be determined. In the present study, we confirmed that reduced miR-212 expression was present in NSCLC tissues and cell lines. Our clinical analysis revealed that the reduced miR-212 expression was significantly correlated with poor prognostic features including positive lymph node metastasis and advanced tumor-node-metastasis (TNM) stage...

The epithelial-to-mesenchymal transition (EMT) is an important developmental program exploited by cancer cells to gain mesenchymal features. Transcription factors globally regulating processes during EMT are often referred as 'master regulators' of EMT, and include members of the Snail and ZEB transcription factor families. The SRY-related HMG box (SOX) 4 transcription factor can promote tumorigenesis by endowing cells with migratory and invasive properties, stemness, and resistance to apoptosis, thereby regulating key aspects of the EMT program...

The sex-determining region Y-related high-mobility group box transcription factor 4 (SOX4) plays a fundamental role during embryogenesis and controls cell fate and differentiation. Recently, increased SOX4 expression has been reported in various cancer types, contributing to the progression and survival of cancer cells. However, the distinct functions and downstream targets of SOX4 remain to be fully elucidated. In this study, we initially found elevated SOX4 expression in melanoma. SOX4 regulates apoptosis and cell cycle arrest, affects glucose consumption and lactate production, and consequently, promotes melanoma cell proliferation...

BACKGROUND: Long non-coding RNAs (lncRNAs) play a variety of cellular roles, including regulation of transcription and translation, leading to alterations in gene expression. Some lncRNAs modulate the expression of chromosomally adjacent genes. Here, we assess the roles of the lncRNA CASC15 in regulation of a chromosomally nearby gene, SOX4, and its function in RUNX1/AML translocated leukemia. RESULTS: CASC15 is a conserved lncRNA that was upregulated in pediatric B-acute lymphoblastic leukemia (B-ALL) with t (12; 21) as well as pediatric acute myeloid leukemia (AML) with t (8; 21), both of which are associated with relatively better prognosis...
