Analysis of integrin mRNA in human and rodent tumor cells.

Abstract:

:Several human and rodent tumor cell lines were examined for the presence of integrin mRNAs by dot- and Northern-blot analysis. All tumor cells tested expressed mRNAs for alpha 5, alpha IIb, beta 1 and beta 3. The mRNA of beta 2 integrin was not detectable and that of alpha V integrin was found only in certain cells. Northern blotting was carried out in three selected tumor cell lines: Clone A, HEL and B16a. An apparent difference in the mRNA species coding for the alpha IIb beta 3 integrin, but not for alpha 5 and beta 1, was found. Our result suggests that alternative splicing of integrin genes may be one of the important mechanisms in regulating alpha IIb beta 3 expression and function in different tumor cells.

  • Transcription factor WRKY30 mediates resistance to Cucumber mosaic virus in Arabidopsis.

    abstract::WRKY transcription factors are key regulators in regulating abiotic or biotic stress response in Arabidopsis. Previous studies showed that WRKY30 expression was induced by oxidative stress treatment, fungal elicitor, SA and ABA. However, functions of WRKY30 on viral defense are not well studied. Here, we found that Ar...
