Regulation of cyclin D1 gene expression

Cyclin D1 is a key regulator of cell proliferation and its expression is subject to both transcriptional and post-transcriptional regulation. in different cellular contexts, different pathways assume a dominant role in regulating its expression, whereas their disregulation can contribute to overexpression of cyclin D1 in tumorigenesis. Here, we discuss the ability of the NF-kappa B (nuclear factor kappa B)/IKK [I kappa B (inhibitor of NF-kappa B) kinase] pathways to regulate cyclin D1 gene transcription and also consider the newly discovered role of the SNARP (SNIP1/SkIP-associated RNA processing) complex as a co-transcriptional regulator of cyclin D1 RNA stability.
