PCAT1, a novel prostate cancer ncRNA alternately demonstrating either repression by PRC2 or an active role in promoting cell proliferation through transcriptional regulation of target genes.
Contents
Annotated Information
Name
PCAT1:prostate cancer associated transcript 1 (non-protein coding) (HGNC:43022)
PCA1, PCAT-1[1]
Characteristics
PCAT-1 resides in the 8q24 “gene desert” locus. PCAT-1 is located in the chromosome 8q24 gene desert approximately 725 kb upstream of the c-MYConcogene[1].
Function
PCAT-1 is a marker of aggressive cancer and a PRC2-repressed ncRNA[1]
PCAT-1 biology may exhibit two distinct modalities: one in which PRC2 represses PCAT-1 and a second in which active PCAT-1 promotes cell proliferation. PCAT-1 and PRC2 may therefore characterize distinct subsets of prostate cancer[1].
PCAT-1 can stratify overall survival and correlated with distant metastasis in CRC patients, and the prognosis of CRC may be influenced by PCAT-1 expression, which suggested that PCAT-1 may be a potential diagnostic target in patients with colorectal cancer[2].
Regulation
PCAT-1 was regulated by PRC2 complex in prostate cancer cells[1].
Expression
PCAT-1, which is markedly overexpressed in a subset of prostate cancers, particularly metastases, and may contribute to cell proliferation in these tumors[1]
PCAT-1 was overexpressed in colorectal cancer[2].
Comparison of PCAT-1 expression levels between CRC tumor tissues and matched normal tissues by real time PCR analysis[2]
siRNA sequences (in sense format) were as follows:
| PCAT-1 | Sequence |
|---|---|
| siRNA 1 | UUAAAGAGAUCCACAGUUAUU[1] |
| siRNA 2 | GCAGAAACACCAAUGGAUAUU[1] |
| siRNA 3 | AUACAUAAGACCAUGGAAAU[1] |
| siRNA 4 | GAACCUAACUGGACUUUAAUU[1] |
| EZH2 | Sequence |
| siRNA | GAGGUUCAGACGAGCUGAUUU[1] |
