To compare the long-term recovery of gene expression in dorsal root ganglion (DRG) neurons under conditions of regeneration vs. non-regeneration, Northern blotting and in situ hybridization were used to assess steady-state neurofilament (NF) and beta tubulin mRNA levels 12 weeks following axonal injury. Adult male rats sustained either a crush lesion of the mid-sciatic nerve (regeneration occur...

Changes in small non-coding RNAs such as micro RNAs (miRNAs) can serve as indicators of disease and can be measured using next-generation sequencing of RNA (RNA-seq). Here, we highlight the need for approaches that complement RNA-seq, discover that northern blotting of small RNAs is biased against short sequences and develop a protocol that removes this bias. We found that multiple small RNA-se...

BSMV (barley stripe mosaic virus) particles were obtained in a pure state from infected host plant tissues of Hordeum vulgare. The three genomic parities (alpha, beta and gamma) were amplified by PCR using specific primers for each particle; each was cloned. Partial sequence of the alpha, beta and gamma segments was determined for the Egyptian isolate of barley stripe mosaic virus (BSMV AE1). A...

Aeluropus lagopoides is a salt and drought tolerant grass from Poaceae family, distributed widely in arid regions. There is almost no information about the genetics or genome of this close relative of wheat that stands harsh conditions of deserts. Differential Display Amplified fragment length polymorphism (DD-AFLP) led to the improvement of a non-radioactive method for which many parameters we...

The content of GSH transferase mRNAs in poly(A)-containing RNA isolated from eight rat tissues was examined by immunoprecipitation of cell-free translation products and by Northern blotting. Considerable tissue-specific distribution and heterogeneity of immunoprecipitable GSH transferase subunits 1 and 2 synthesized in vitro was observed. These results were confirmed by Northern blotting using ...

In the present study, we analysed human choriocarcinoma cell lines for abnormalities in the tumour-suppressor gene p53 by Southern blotting, Northern blotting, non-radioisotopic single-stranded conformational polymorphism (SSCP) and complementary DNA sequencing. In all cell lines (Bewo, GCH-1, GCH-2, SCH, JAR, JEG-3, NUC-1 and HCCM-5), no p53 gene abnormality was detected by using Southern blot...

To study host response to CagA, human gastric cancer cell line AGS was infected with a Helicobacter pylori type I wild-type or isogenic cagA-negative mutant. Differentially expressed genes were identified using cDNA array technology. By Northern blotting, downregulation of focal adhesion kinase and upregulation of LIM kinase mRNA in the presence of CagA were clearly verified. Furthermore, upreg...
