Description: IC50 Value: N/A Nuclear yellow (Hoechst S769121) exhibits excitation/emission maxima ~335/495 nm when bound to DNA. Hoechst stains are part of a family of blue fluorescent dyes used to stain DNA. These Bis-benzimides were originally developed by Hoechst AG, which numbered all their compounds so that the dye Hoechst 33342 is the 33342nd compound made by the company. There are three related Hoechst stains: Hoechst 33258, Hoechst 33342, and Hoechst 34580. The dyes Hoechst 33258 and Hoechst 33342 are the ones most commonly used and they have similarexcitation/emission spectra. Both dyes are excited by ultraviolet light at around 350 nm, and both emit blue/cyan fluorescent light around anemission maximum at 461 nm. Unbound dye has its maximum fluorescence emission in the 510-540 nm range. Hoechst dyes are soluble in water and in organic solvents such as dimethyl formamide or dimethyl sulfoxide. Concentrations can be achieved of up to 10 mg/mL. Aqueous solutions are stable at 2-6 °C for at least six months when protected from light. For long-term storage the solutions are instead frozen at ≤-20 °C. The dyes bind to the minor groove of double-stranded DNA with a preference for sequences rich in adenine andthymine. Although the dyes can bind to all nucleic acids, AT-rich double-stranded DNA strands enhance fluorescence considerably. Hoechst dyes are cell-permeable and can bind to DNA in live or fixed cells. Therefore, these stains are often called supravital, which means that cells survive a treatment with these compounds. Cells that express specific ATP-binding cassette transporter proteins can also actively transport these stains out of their cytoplasm. in vitro: N/A in vivo: N/A Clinical trial: N/A

The stress granule component G3BP is a novel interaction partner for the nuclear shuttle proteins of the nanovirus pea necrotic yellow dwarf virus and geminivirus abutilon mosaic virus.[Pubmed:27693920]
Virus Res. 2017 Jan 2;227:6-14.
Stress granules (SGs) are structures within cells that regulate gene expression during stress response, e.g. viral infection. In mammalian cells assembly of SGs is dependent on the Ras-GAP SH3-domain-binding protein (G3BP). The C-terminal domain of the viral nonstructural protein 3 (nsP3) of Semliki Forest virus (SFV) forms a complex with mammalian G3BP and sequesters it into viral RNA replication complexes in a manner that inhibits the formation of SGs. The binding domain of nsP3 to HsG3BP was mapped to two tandem 'FGDF' repeat motifs close to the C-terminus of the viral proteins. It was speculated that plant viruses employ a similar strategy to inhibit SG function. This study identifies an Arabidopsis thaliana NTF2-RRM domain-containing protein as a G3BP-like protein (AtG3BP), which localizes to plant SGs. Moreover, the nuclear shuttle protein (NSP) of the begomovirus abutilon mosaic virus (AbMV), which harbors a 'FVSF'-motif at its C-terminal end, interacts with the AtG3BP-like protein, as does the 'FNGSF'-motif containing NSP of pea necrotic yellow dwarf virus (PNYDV), a member of the Nanoviridae family. We therefore propose that SG formation upon stress is conserved between mammalian and plant cells and that plant viruses may follow a similar strategy to inhibit plant SG function as it has been shown for their mammalian counterparts.
A redox-sensitive yellow fluorescent protein sensor for monitoring nuclear glutathione redox dynamics.[Pubmed:25311129]
Methods Mol Biol. 2015;1228:159-69.
Intracellular redox homeostasis is crucial for many cellular functions, but accurate measurements of cellular compartment-specific redox states remain technically challenging. Genetically encoded biosensors, including the glutathione-specific redox-sensitive yellow fluorescent protein (rxYFP), provide an alternative approach to overcome the limitations of conventional glutathione/glutathione disulfide (GSH/GSSG) redox measurements. In this chapter we describe methods to measure the nuclear rxYFP redox state in human cells by a redox Western blot technique. A nucleus-targeted rxYFP sensor can be used to sense nuclear steady-state and dynamic redox changes in response to oxidative stress. Complementary to existing redox sensors and conventional redox measurements, nucleus-targeted rxYFP sensors provide a novel tool for examining nuclear redox homeostasis in mammalian cells, permitting high-resolution readout of steady glutathione state and dynamics of redox changes. The technique described may be used with minimal variations to study the effects of stress conditions which lead to glutathione redox changes.
Yellow mosaic symptom caused by the nuclear shuttle protein gene of mungbean yellow mosaic virus is associated with single-stranded DNA accumulation and mesophyll spread of the virus.[Pubmed:27640432]
Acta Virol. 2016;60(3):224-33.
Mungbean yellow mosaic virus-[India:Vigna] (MYMV-[IN:Vig]), a blackgram isolate of MYMV, causes yellow mosaic disease in blackgram and mungbean. Two variable DNA-B components, KA22 and KA27, cause distinct symptoms in blackgram [V. mungo (L.) Hepper] with the same DNA-A component. KA22 + DNA-A-agroinoculated blackgram plants displayed yellow mosaic symptom and accumulated high levels of viral single-stranded (ss) DNA. KA27 + DNA-A-agroinoculated blackgram plants displayed severe stunting symptom and accumulated very low levels of viral ssDNA. However, in mungbean [V. radiata (L.) Wilczek], KA27 + DNA-A caused yellow mosaic symptom and a high level of viral ssDNA accumulated. Swapping of KA27 DNA-B with the nuclear shuttle protein gene (NSP) of KA22 DNA-B (KA27xKA22 NSP) caused yellow mosaic symptom in blackgram, suggesting that KA22 NSP is the determinant of yellow mosaic symptom. Interestingly, KA27xKA22 NSP-infected blackgram plants accumulated high levels of viral ssDNA, comparable to that of KA22 DNA-B infection, suggesting that the KA22 NSP is responsible for accumulation of high levels of viral ssDNA. MYMV distribution was studied in blackgram and mungbean plants by leaf tissue hybridization, which showed mesophyll spread of the virus in KA22-infected blackgram leaflets and in KA27-infected mungbean leaflets, both of which displayed yellow mosaic symptom. However, the virus did not accumulate in the mesophyll in the case of KA27-infected blackgram leaflets. Interestingly, the swapped KA27xKA22 NSP-infected blackgram leaflets showed mesophyll accumulation of the virus, suggesting that KA22 NSP determines its mesophyll spread.
[Ecotopic Differentiation of Yellow-Anthered and Red-Anthered Forms of Scots Pine by Karyological Traits and Nuclear DNA Content].[Pubmed:26638235]
Izv Akad Nauk Ser Biol. 2015 Sep-Oct;(5):477-86.
A comparative study of yellow-anthered and red-anthered forms of Scots pine, growing in hydrothermally contrasting bog and upland ecotopes, was performed by karyological traits and nuclear DNA content. Some differences were revealed between yellow-anthered and red-anthered forms of pine as components of intraspecific diversity in'the frequency of occurrence of violations in the number of chromosomes, chromosome sizes (total length of diploid set, absolute and relative lengths), the centromeric index, the localization of secondary constrictions in chromosomes, and the amount of DNA.
