c-myc mRNA in cytoskeletal-bound polysomes in fibroblasts.
نویسندگان
چکیده
3T3 fibroblasts were treated sequentially with 25 mM-KCl/0.05% Nonidet P40, 130 mM-KCl/0.05% Nonidet P40 and finally with 1% Nonidet P40/1% deoxycholate in order to release free, cytoskeletal-bound and membrane-bound polysomes respectively. The membrane-bound fraction was enriched in the mRNA for the membrane protein beta 2-microglobulin, whereas the cytoskeletal-bound polysomes were enriched in c-myc mRNA. Actin mRNA was present in both free and cytoskeletal-bound polysomes. The results suggest that cytoskeletal-bound polysomes are involved in the translation of specific mRNA species.

Competition between the signal sequence and a 3'UTR localisation signal during redirection of beta-globin mRNA to the endoplasmic reticulum: implications for biotechnology.
Secretion of an intracellular protein from a cell factory requires as a first step the redirection of the mRNA for synthesis of the protein on the endoplasmic reticulum. The feasibility of retargeting a mRNA coding for an intracellular protein to the endoplasmic reticulum was investigated using Ltk- fibroblasts stably transfected with gene constructs in which rabbit beta-globin coding region an...
متن کاملRNA-dependent association with myosin IIA promotes F-actin-guided trafficking of the ELAV-like protein HuR to polysomes
The role of the mRNA-binding protein human antigen R (HuR) in stabilization and translation of AU-rich elements (ARE) containing mRNAs is well established. However, the trafficking of HuR and bound mRNA cargo, which comprises a fundamental requirement for the aforementioned HuR functions is only poorly understood. By administering different cytoskeletal inhibitors, we found that the protein kin...
متن کاملEvaluation of c-Myc mRNA Expression Level in Benign Prostatic Hyperplasia and Prostatic Adenocarcinoma Tissues and Its Correlation with Clinicopathological Characteristics
Background and Aims: Prostate cancer (PCa) is one of the most common cancers among men in Iran. Since changes in the regulation of proto-oncogenes expression are the main causes of most human cancers, including PCa, evaluating the expression of marker genes can be helpful for early diagnosis of cancer and better understanding of its etiology. The present study compared c-Myc expression level in...
متن کاملAnnexin II is associated with mRNAs which may constitute a distinct subpopulation.
Protein-mRNA interactions affect mRNA transport, anchorage, stability and translatability in the cytoplasm. During the purification of three subpopulations of polysomes, it was observed that a 36-kDa protein, identified as annexin II, is associated with only one specific population of polysomes, namely cytoskeleton-associated polysomes. This association appears to be calcium-dependent since it ...
متن کاملPolysome trafficking of transcripts and microRNAs in regenerating liver after partial hepatectomy.
Liver regeneration after 70% partial hepatectomy (PH) in rats induces >95% of hepatocytes to undergo two rounds of semisynchronous cell replication. Gene expression is controlled primarily by posttranscriptional processing, including changes in mRNA stability. However, the translational activity of a specific mRNA can also be modulated after PH, resulting in significant uncoupling of protein an...
