Differential expansion of a number of human short tandem repeats (STRs) at the critical core promoter and 5' untranslated region (UTR) support the hypothesis that at least some of these STRs may provide a selective advantage in human evolution. Following a genome-wide screen of all human protein-coding gene 5' UTRs based on the Ensembl database ( http://www.ensembl.org ), we previously reported that the longest STR in this interval is a (GA)32, which belongs to the X-linked zinc finger MYM-type containing 3 (ZMYM3) gene...

In this study, three nanos gene subtypes (Lcnanos1, Lcnanos2 and Lcnanos3) from Larimichthys crocea, were cloned and characterized. We determined the spatio-temporal expression patterns of each subtype in tissues as well as the cellular localization of mRNA in embryos. Results showed that deduced Nanos proteins have two main homology domains: N-terminal CCR4/NOT1 deadenylase interaction domain and highly conserved carboxy-terminal region bearing two conserved CCHC zinc-finger motifs. The expression levels of Lcnanos1 in testis were significantly higher than other tissues, followed by heart, brain, eye, and ovary...

MicroRNAs (miRNAs) are some short RNAs that regulate multiple biological functions at post-transcriptional levels, such as tumorigenic processes, inflammatory lesions and cell apoptosis. Zinc finger E-box binding homeobox factor 1 (ZEB1) is a crucial mediator of epithelial-mesenchymal transition (EMT). It induces malignant progression of various cancers including human esophageal squamous-cell carcinoma (ESCC). In this study, we found that miR-128-3p was downregulated in ESCC tissues and cells by using PCR...

Senescence is a complex multiple factor proces, which is still poorly understood. The purpose of this study was to find the proteome of cultured human fetal lung diploid fibroblasts (2BS) of different population doubling (PD), as well as the altered proteome induced by salidroside (SAL) in 2BS cells. Proteins were identified by two-dimensional electrophoresis (2-DE) combining matrix-assisted laser desorption/ionization-time and flight mass spectrometry (MAL DI-TOF/MS). As a result, we found 16 proteins with two-fold variations in senescent cells or after SAL treatment, some being reduced such as reticulocalbin-1, heat shock protein beta-6, elongation factor 1-delta, F-actin-capping protein subunit alpha-1, and chloride intracellular channel 1...

Large cell neuroendocrine carcinoma (LCNEC) of the lung is a highly aggressive tumor without established standard treatment. The Hedgehog (Hh) signal, which is critical in embryogenesis, is known to play important roles in maintaining a malignant phenotype in various cancers. The present study explored the possibility of targeting the Hh signal in the treatment of LCNEC by suppressing Hh downstream molecules, Smoothened (Smo) and GLI family zinc finger 1/2 (Gli1/2), in 3 human LCNEC cell lines. Smo inhibitor, BMS-833923, and Gli inhibitor, GANT61, downregulated Gli1 and 2, resulting in the suppression of the cell viability of the 3 cell lines as assessed using an MTT assay...

Plant hormone salicylic acid (SA) plays critical roles in defense signaling against biotrophic pathogens. Pathogen inoculation leads to SA accumulation in plants. SA activates a transactivator protein NPR1, which, in turn, transcriptionally activates many defense response genes. Reports also suggest the presence of NPR1-independent pathways for SA signaling in Arabidopsis. Here, we report the characterization of a zinc-finger protein-coding gene AtOZF1 that positively influences NPR1-independent SA signaling...

Extraskeletal myxoid chondrosarcoma is a rare subtype of sarcoma that affects the soft tissue and bones in middle-aged and elderly adults. Its diagnosis can be challenging, with the differential diagnoses including a wide variety of mesenchymal tumors. The line of differentiation of extraskeletal myxoid chondrosarcoma has been controversial, but recent evidence suggests a neuroendocrine phenotype. INSM1 is a zinc-finger transcription factor that plays a pivotal role in neuroendocrine differentiation, and has been proposed as a promising immunohistochemical marker of neuroendocrine carcinoma...

Aggregating evidence suggests that genetic determinants play a pivotal role in the pathogenesis of the congenitally bicuspid aortic valve (BAV). BAV is of pronounced genetic heterogeneity, and the genetic components underlying BAV in an overwhelming majority of patients remain elusive. In the current study, the whole coding exons and adjacent introns, as well as 5' and 3' untranslated regions of the GATA4 gene, which codes for a zinc-finger transcription factor crucial for the normal development of the aortic valve, were screened by direct sequencing in 150 index patients with congenital BAV...

MicroRNA-186-5p (miR-186-5p) is upregulated and exhibits as a crucial oncogene in various human tumors. However, the functions and underlying mechanisms of this microRNA on colorectal cancer remain largely unknown. Here, we report that miR-186-5p share a lower expression in colorectal cancer cell lines (HT116, H29, SW620 and LoVo) than in normal colonic epithelial cell line NCM460. MiR-186-5p overexpression inhibits proliferation, metastasis and epithelial-to-mesenchymal transition (EMT) of colorectal cancer cell line LoVo...

GATA transcription factor is a family of DNA-binding proteins that can recognize and bind to sequence of (A/T) GATA (A/G). In the present study, a GATA-like protein (named as EsGLP) was characterized from Eriocheir sinensis, including an 834 bp full length open reading frame of EsGLP, encoding a polypeptide of 277 amino acids. The deduced amino acid sequence of EsGLP contained one conserved GATA-type zinc finger of the form Cys-X2-Cys-X17-Cys-X2-Cys, with four cysteine sites. The EsGLP mRNA transcripts were mainly detected in the hematopoietic tissue, hepatopancreas and gonad...

REVIEW
Levon M Khachigian
Yin Yang-1 (YY1) is a zinc finger protein and member of the GLI-Kruppel family that can activate or inactivate gene expression depending on interacting partners, promoter context and chromatin structure, and may be involved in the transcriptional control of ∼10% of the total mammalian gene set. A growing body of literature indicates that YY1 is overexpressed in multiple cancer types and that increased YY1 levels correlate with poor clinical outcomes in many cancers. However the role of YY1 in the promotion or suppression of tumor growth remains controversial and its regulatory effects may be tumor cell type dependent at least in experimental systems...

The dermal shank pigmentation, one of the defining traits of chicken breeds, is caused by an abnormal deposition of melanin in the dermis of the shank. The abnormal deposition is controlled by the sex-linked inhibitor of dermal melanin (Id). In this study, we aim to locate the gene responsible for the dermal shank pigmentation in chickens by an association analysis and a differential expression analysis. Based on our results, 72 single-nucleotide polymorphisms (SNPs) located in Z chromosome (chrZ): 71-73 Mb (galGal3) were selected to further explore their relationships with the dermal shank pigmentation in pure lines of 96 Gushi hens and 96 Gushi hens with a yellow shank skin colour...

The malignancy of non-small cell lung cancer (NSCLC) largely results from its invasive manner. Secreted frizzled-related proteins (SFRPs) have been recently found to suppress the invasiveness of some cancers. On the other hand, the methylation of SFRPs increases protein degradation to reduce the activity of SFRPs, resulting in increased tumor cell invasion and cancer metastasis. However, the role of SFRPs in the invasion of NSCLC has not been reported. Here we analyzed the regulation of SFRPs in NSCLC cells and its effects on cell invasion...

Liver-specific disruption of the type 2 deiodinase gene (Alb-D2KO) results in resistance to both diet-induced obesity and liver steatosis in mice. Here, we report that this is explained by an ∼60% reduction in liver zinc-finger protein-125 (Zfp125) expression. Zfp125 is a Foxo1-inducible transcriptional repressor that causes lipid accumulation in the AML12 mouse hepatic cell line and liver steatosis in mice by reducing liver secretion of triglycerides and hepatocyte efflux of cholesterol. Zfp125 acts by repressing 18 genes involved in lipoprotein structure, lipid binding, and transport...

Ring1-YY1-binding protein (RYBP) is a member of the non-canonical polycomb repressive complex 1 (PRC1), and like other PRC1 members, it is best described as a transcriptional regulator. However, several PRC1 members were recently shown to function in DNA repair. Here, we report that RYBP preferentially binds K63-ubiquitin chains via its Npl4 zinc finger (NZF) domain. Since K63-linked ubiquitin chains are assembled at DNA double-strand breaks (DSBs), we examined the contribution of RYBP to DSB repair. Surprisingly, we find that RYBP is K48 polyubiquitylated by RNF8 and rapidly removed from chromatin upon DNA damage by the VCP/p97 segregase...

Seven in absentia (SINA) protein is one subgroup of ubiquitin ligases possessing an N-terminal cysteine-rich Really Interesting New Gene (RING) domain, two zinc-finger motifs and a C-terminal domain responsible for substrate-binding and dimerization. In tomato (Solanum Lycopersicum), the SINA gene family has six members and we characterize in this study all tomato SINA (SlSINA) genes and the gene products. Our results show that SlSINA genes are differentially regulated in leaf, bud, stem, flower and root. All SlSINA proteins possess RING-dependent E3 ubiquitin ligase activity, exhibiting similar specificity towards the E2 ubiquitin-conjugating enzyme...

Inherited retinal diseases (IRDs) display an enormous genetic heterogeneity. Whole exome sequencing (WES) recently identified genes that were mutated in a small proportion of IRD cases. Consequently, finding a second case or family carrying pathogenic variants in the same candidate gene often is challenging. In this study, we searched for novel candidate IRD gene-associated variants in isolated IRD families, assessed their causality, and searched for novel genotype-phenotype correlations. Whole exome sequencing was performed in 11 probands affected with IRDs...

The understanding of the mechanism underlying human neural development has been hampered due to lack of a cellular system and complicated ethical issues. Human embryonic stem cells (hESCs) provide an invaluable model for dissecting human development because of unlimited self-renewal and the capacity to differentiate into nearly all cell types in the human body. In this study, using a chemical defined neural induction protocol and molecular profiling, we identified Fez family zinc finger 1 (FEZF1) as a potential regulator of early human neural development...

As a transcription factor, zinc finger E-box binding homeobox 2 (ZEB2) includes multiple functional domains which interact with kinds of transcriptional co-effectors. It has been reported that ZEB2 was involved in signal transduction and multiple cellular functions. However, the functional role of ZEB2 in inflammation is still obscure. The aim of the current study is to explore the function of ZEB2 in inflammation cytokine secretion and the role of the nuclear factor-κB (NF-κB) signaling pathway in lipopolysaccharide (LPS)-induced human proximal tubule cell line (HK-2) cells...
