Fragile X syndrome (FXS) is caused by the loss of expression of fragile X mental retardation protein (FMRP), a selective RNA-binding protein that negatively regulates mRNA substrates. FMRP can regulate the translation via the cross-talk with the miRNA machinery, but the functional association among FMRP, miRNAs and mutual target mRNAs ...

Extracellular-regulated kinases and p38 mitogen-activated protein kinases are activated in innate (and adaptive) immunity and signal via different routes to alter the stability and translation of various cytokine mRNAs, enabling immune cells to respond promptly. This regulation involves mRNA elements, such as AU-rich motifs, and mRNA-binding proteins, such as tristetraprolin ...

mRNA decapping commits a transcript to complete turnover in eukaryotic cells. In yeast, general mRNA decapping requires the Dcp1/Dcp2 decapping enzyme and a set of decapping activators including Pat1, Dhh1, Edc3, and the Lsm1-7 complex. The exact function and mode of action for each of these decapping activators in mRNA ...

17β-hydroxysteroid dehydrogenases (17β-HSDs) are important enzymes catalyzing steroids biosynthesis and metabolism in vertebrates. Although studies indicate steroids play a potential role in reproduction of molluscs, little is known about the presence and function of 17β-HSDs in molluscs. In the present study, a full-length cDNA encoding 17β-HSD type 8 (17β-HSD8) was ...

Hox proteins form complexes with TALE cofactors from the Pbx and Prep/Meis families to control transcription, but it remains unclear how Hox:TALE complexes function. Examining a Hoxb1b:TALE complex that regulates zebrafish hoxb1a transcription, we find maternally deposited TALE proteins at the hoxb1a promoter already during blastula stages. These TALE factors recruit ...

RNA-binding proteins are of vital importance for mRNA functioning. Among these, poly(A)-binding proteins (PABPs) are of special interest due to their participation in virtually all mRNA-dependent events that is caused by their high affinity for A-rich mRNA sequences. Apart from mRNAs, PABPs interact with many proteins, thus promoting their involvement ...

The kinase-inducible domain interacting (KIX) domain is a highly conserved independently folding three-helix bundle that serves as a docking site for transcription factors, whereupon promoter activation and target specificity are achieved during gene regulation. This docking event is a harbinger of an intricate multi-protein assembly at the transcriptional apparatus and ...

Previously, we identified proteins showing a differential acetylation pattern during adipogenic differentiation. Here, we examined the role of malate dehydrogenase 2 (MDH2) acetylation in the adipogenesis of 3T3-L1 preadipocytes. The acetylation level of MDH2 showed a dramatic increase during adipogenesis. The overexpression of wild-type MDH2 induced the significant acceleration of ...

The enzyme 3β-hydroxysteroid dehydrogenase/Δ(5)-Δ(4)-isomerase (3β-HSD) catalyzes the biosynthesis of all steroid hormones. The molecular mechanisms regulating porcine adrenal 3β-HSD expression in different breeds are still poorly understood. In this study, we aimed to compare the expression of 3β-HSD between preweaning purebred Large White (LW) and Erhualian (EHL) piglets and to ...

Regulated expression of glucose-6-phosphate dehydrogenase (G6PD) is due to changes in the rate of pre-mRNA splicing and not changes in its transcription. Starvation alters pre-mRNA splicing by decreasing the rate of intron removal, leading to intron retention and a decrease in the accumulation of mature mRNA. A regulatory element within ...

Bone morphogenetic proteins (BMPs) signaling essentially regulates a wide range of biological responses. Although multiple regulators at different layers of the receptor-effectors axis have been identified, the mechanisms of homeostatic BMP signaling remain vague. Herein we demonstrated that myotubularin-related protein 4 (MTMR4), a FYVE domain-containing dual-specificity protein phosphatase (DUSP), preferentially ...

Cyclooxygenase (COX)-2 is an inducible inflammatory protein whose expression is partially regulated at the post-transcriptional level. We investigated whether glyceraldehyde 3-phosphate dehydrogenase (GAPDH) binds to the AU-rich element (ARE) of COX-2 mRNA for its degradation. Knockdown of GAPDH in hepa1c1c7 cells significantly enhanced COX-2 expressions. Recombinant GAPDH bound to the ...

We demonstrate for the first time that the pro-inflammatory cytokine interleukin (IL)-18 stimulates rapid and significant proliferation of SMC derived from human saphenous vein (VSMC), but not coronary artery. IL-18 also stimulates VSMC growth. Further investigations revealed that IL-18-induced VSMC proliferation was Wnt inducible secreted protein-1 (WISP1) dependent. In addition ...

We describe here the prenatal telencephalic expression of Dlx6 RNA and β-galactosidase driven from a mutant Dlx6 locus. The mutant Dlx6 allele, which we believe is either a null or severe hypomorph, has an IRES-lacZ-neomycin resistance cassette inserted into the Dlx6 homeobox coding sequence (Dlx6(LacZ) ). We compared expression from ...

Protein Inhibitor of Activated Signal Transducer and Activators of Transcription 3 (PIAS3) is a molecule that regulates STAT3 and has antiproliferative properties. Glioblastoma and squamous cell lung cancer lack PIAS3 expression. To test the hypothesis that PIAS3 transcriptional effects are STAT3-independent, we developed models for STAT3 knockdown and PIAS3 over-expression. ...

Few effective therapies exist for the treatment of castration-resistant prostate cancer (CRPC). Recent evidence suggests that CRPC may be caused by augmented androgen/androgen receptor (AR) signaling, generally involving AR overexpression. Aberrant androgen/AR signaling associated with AR overexpression also plays a key role in prostate carcinogenesis. Although AR overexpression could be ...
