Forkhead Box Proteins: Tuning Forks for Transcriptional Harmony REVIEWS Forkhead box proteins: tuning forks for transcriptional harmony Eric W.‑F. Lam1, Jan J. Brosens2, Ana R. Gomes1 and Chuay-Yeng Koo1 Abstract | Forkhead box (FOX) proteins are multifaceted transcription factors that are responsible for fine-tuning the spatial and temporal expression of a broad range of genes both during development and in adult tissues. This function is engrained in their ability to integrate a multitude of cellular and environmental signals and to act with remarkable fidelity. Several key members of the FOXA, FOXC, FOXM, FOXO and FOXP subfamilies are strongly implicated in cancer, driving initiation, maintenance, progression and drug resistance. The functional complexities of FOX proteins are coming to light and have established these transcription factors as possible therapeutic targets and putative biomarkers for specific cancers.

These rSNP alleles alter the DNA landscape for potential transcriptional factors (TFs) to attach resulting in changes in transcriptional factor binding sites (TFBS). These TFBS changes are examined with respect to asthma which has been found to be significantly asso- ciated with the rSNPs. Keywords TBXA2R, rSNPs, TFBS, Asthma 1. Introduction Asthma is a chronic inflammatory condition of the airways characterized by recurrent episodes of reversible air- way obstruction and increased bronchial hyper-responsiveness which results from the interactions between gen- es and environmental factors [1]-[3]. Asthma causes episodes of wheeze, cough, and shortness of breath [4]. Re- cent studies indicate that the genetic factors of childhood-onset asthma differ from those of adult-onset asthma [3] [5].

The aim of this study is to establish whether mutation of FOXC1 contributes toward other developmental eye anomalies, namely anophthalmia, microphthalmia, and coloboma. Methods: The coding sequence and 3`-UTR of FOXC1 was analyzed in 114 subjects with severe developmental eye anomalies by bidirectional direct sequencing. Results: Four coding FOXC1 variations (two novel missense variations, one insertion, and one novel deletion) were identified in the cohort. Two noncoding variations were also identified in the 3′-UTR. The missense mutations were c. 889C_T and c.1103C_A, resulting in p.Pro297Ser and p.Thr368Asn, respectively. The c.889C_T transition was identified in 19 of the 100 unaffected control samples. The c.1103C_A transversion resulted in a conservative substitution in an unconserved amino acid and was deemed unlikely to be pathogenic. A c.1142_1144insGCG change resulting in p.Gly380ins, which was previously associated with kidney anomalies, was identified in 44 of the 114 affected individuals.

Abstract The high mortality rate of gastric cancer (GC) is in part due to the absence of initial disclosure of its biomarkers. The recognition of important genes associated in GC is therefore recommended to advance clinical prognosis, diagnosis and and treatment outcomes. The current investigation used the microarray dataset GSE113255 RNA seq data from the Gene Expression Omnibus database to diagnose differentially expressed genes (DEGs). Pathway and gene ontology enrichment analyses were performed, and a proteinprotein interaction network, modules, target genes - miRNA regulatory network and target genes - TF regulatory network were constructed and analyzed. Finally, validation of hub genes was performed. The 1008 DEGs identified consisted of 505 up regulated genes and 503 down regulated genes.

  • The Forkhead-Box Family of Transcription Factors: Key Molecular Players in Colorectal Cancer Pathogenesis Paul Laissue
    Laissue Molecular Cancer (2019) 18:5 https://doi.org/10.1186/s12943-019-0938-x REVIEW Open Access The forkhead-box family of transcription factors: key molecular players in colorectal cancer pathogenesis Paul Laissue Abstract Colorectal cancer (CRC) is the third most commonly occurring cancer worldwide and the fourth most frequent cause of death having an oncological origin. It has been found that transcription factors (TF) dysregulation, leading to the significant expression modifications of genes, is a widely distributed phenomenon regarding human malignant neoplasias. These changes are key determinants regarding tumour’s behaviour as they contribute to cell differentiation/proliferation, migration and metastasis, as well as resistance to chemotherapeutic agents. The forkhead box (FOX) transcription factor family consists of an evolutionarily conserved group of transcriptional regulators engaged in numerous functions during development and adult life. Their dysfunction has been associated with human diseases. Several FOX gene subgroup transcriptional disturbances, affecting numerous complex molecular cascades, have been linked to a wide range of cancer types highlighting their potential usefulness as molecular biomarkers. At least 14 FOX subgroups have been related to CRC pathogenesis, thereby underlining their role for diagnosis, prognosis and treatment purposes. This manuscript aims to provide, for the first time, a comprehensive review of FOX genes’ roles during CRC pathogenesis. The molecular and functional characteristics of most relevant FOX molecules (FOXO, FOXM1, FOXP3) have been described within the context of CRC biology, including their usefulness regarding diagnosis and prognosis. Potential CRC therapeutics (including genome-editing approaches) involving FOX regulation have also been included. Taken together, the information provided here should enable a better understanding of FOX genes’ function in CRC pathogenesis for basic science researchers and clinicians.

ABSTRACT FOXC1 is a vital member of FOX families which play important roles in biological processes including proliferation, differentiation, apoptosis, migration, invasion, metabolism, and longevity. Here we are focusing on roles of FOXC1 and their mechanisms in cancers. FOXC1 promoted progress of many cancers, such as breast cancer (especially basal-like breast cancer), hepatocellular carcinoma, gastric cancer and so on. FOXC1 was also found to be associated with drug resistance of cancers. FOXC1 promoted metastasis of cancers by increasing expression of MMP7, NEDD9 and Snail. Proliferation and invasion of cancers were increased by FOXC1 by mediating NF-κB, MST1R and KLF4 expression. FOXC1 was associated with development by regulating expression of FGF19 and MSX1.

Glomerular development has been analyzed mainly in mice, whereas analysis of human kidney development has been minimal because of limited access to embryonic kidneys. We previously reported the induction of three-dimensional primordial glomeruli from human induced pluripotent stem (iPS) cells. Here, using transcription activator–like effector nuclease-mediated homologous recombination, we generated human iPS cell lines that express green fluorescent protein (GFP) in the NPHS1 locus, which encodes nephrin, and we show that GFP expression facilitated accurate visualization of nephrin-positive podocyte formation in

  • FOXQ1 Is Overexpressed in Laryngeal Carcinoma and Affects Cell Growth, Cell Cycle Progression and Cell Invasion
    ONCOLOGY LETTERS 10: 2499-2504, 2015 FOXQ1 is overexpressed in laryngeal carcinoma and affects cell growth, cell cycle progression and cell invasion JIE ZHANG1, WEI LI1, SONG DAI2, XUHUI TAI2, JIANPING JIA2 and XING GUO1 1Department of Otolaryngology, The First Affiliated Hospital of China Medical University, Shenyang, Liaoning 110001; 2Department of Otolaryngology, The 463 Hospital of PLA, Shenyang, Liaoning 110007, P.R. China Received September 8, 2014; Accepted June 11, 2015 DOI: 10.3892/ol.2015.3530 Abstract. Forkhead box Q1 (FOXQ1) is a forkhead transcrip- the country's Northeast region (4). Significant predisposing tion factor that is involved in numerous biological processes and factors to the development and progression of LSCC, include has been shown to participate in tumorigenesis. However, the alcohol abuse and tobacco (5). Early stage LSCC may be clinical significance of the expression of this protein in laryn- effectively treated with surgery or radiotherapy (6). When geal carcinoma, and the mechanisms underlying its regulation diagnosed at an advanced stage, this disease usually requires in this disease remain unclear. The aim of present study was a combination of treatment modalities. However, although to measure the expression of FOXQ1 in laryngeal carcinoma, such combined therapy has improved local control and and to examine its effect on tumorigenesis. In the present study, overall quality of life, the local recurrence rate varies from reverse transcription‑quantitative polymerase chain reaction and 10-50%, depending on tumor stage and the overall survival western blotting were employed to measure FOXQ1 expression rate has not improved significantly over two decades (7,8). in laryngeal carcinoma tissue samples, small interfering RNA Therefore, it is necessary to identify novel biomarkers for specific to FOXQ1, was transfected into Hep2 cells and its effect use in the diagnosis of LSCC.
