      More Details Abstract Fulltext PDF

      Estradiol-induced incorporation of radioactive uridine and leucine into the uterus of rat was inhibited by simultaneous treatment with an analogue of gonadotropin releasing hormone. The inhibitory action of gonadotropin releasing hormone was not mediated through modulation of estradiol receptor content. However, estradiol-induced increase in the level of poly(A) polymerase was inhibited by gonadotropin releasing hormone analogue, indicating that the inhibitory effect might involve post-transcriptional phenomenon.

    • Hormonal regulation of poly(A) polymerase in the testis of rat

      More Details Abstract Fulltext PDF

      Polyadenylation of mRNA is a post-transcriptional phenomenon and is catalysed by both nuclear and cytoplasmic poly(A) polymerases. In rat testis the specific activity of cytoplasmic poly(A) polymerase increased with age reaching a peak value in 80 days. After this time the activity was maintained at a slightly lower level for the next 280 days. Follicle stimulating hormone, luteinizing hormone, human chorionic gonadotropin, pregnant mare serum gonadotropin and a gonadotropin releasing hormone analogue significantly increased the enzyme activity in immature rat testis. These results show that testicular poly(A) polymerase was probably under the influence of gonadotropic hormones.

      Forthcoming Special issue.

    • To trigger further research on plant mitochondria, the Journal of Biosciences is bringing out a special issue titled "Plant Mitochondria: Properties and Interactions with Other Organelles".

      Plant mitochondria are quite distinct and have unique features, such as a cyanide-insensitive alternate pathway. They also interact with chloroplasts to optimize photosynthetic carbon assimilation.

      Submissions are welcome until 30 July 2023. The contributions can be original articles, short communications, reviews, or mini-reviews on any topic related to plant mitochondria.

      Authors can submit their articles online at https://www.editorialmanager.com/jbsc/default2.aspx
