... into the oocyte nucleus became specifically localized in the nucleoli, and endogenous SRP RNA was also detected in oocyte nucleoli by RNA in situ hybridization. An initial step in the assembly of SRP involves the binding of the SRP19 protein to SRP RNA. When green fluorescent protein (GFP)-tagged SRP19 protein...

.... In situ hybridization showed that poly(A) mRNA is abundant and non-uniformly distributed in nearly all axons. The specific transcripts for β-actin and actin-depolymerizing factor (ADF) were also present and non-uniformly distributed in axons, with an approximately hundredfold higher concentration...

... fluorescent in situ hybridization( Moy and Silver, 1999 ). We originally performed this assay in strains lacking the Xrn1 exonuclease, which degrades the 5′ ITS1 fragment. In xrn1Δ cells, the 5′ ITS1 RNA is distributed throughout the cytoplasm because, in these cells, the small ribosomal subunit is exported...

... MAPK expression in those plant cells. In situ hybridization (ISH) showed the presence of MAPK transcripts in the three plant cell types studied, but levels were very low in quiescent cells compared to those in cycling cells. The quantification of labelling density of ISH signals strongly suggests...

... to extracellular matrix breakdown in the human endometrium, both in cultured and non-cultured samples. The source of MMP-1 was identified by in situ hybridization and by immunohistochemistry on serial sections. This was compared with the immunolocalization of other MMPs, steroid receptors, macrophages, and laminin...

..., the level of expression of each subunit varied with the epithelial cell type as demonstrated by in situ hybridization: epidermal and follicular keratinocytes express mostly α and γ subunits (while β was low); a prevalence of β and γ was observed in sweat glands. Thus, it appeared that two out of the three...

Arginyl-tRNA synthetase, elongation factor 1a, ribosomal RNA, and myelin basic protein mRNA were all co-localized in granules in the processes, veins and membrane sheets of the cell...

... patterns as seen by fluorescence in situ hybridization. Transcripts of the HCMV-IE transcription unit were shown to be present in a main nuclear signal in the form of a track or elongated dot and as small nuclear RNA signals that radiate from this site towards the cytoplasm. A similar distribution pattern...
