The lncRNA prostate cancer-associated transcript 1 (PCAT-1) showed potential oncogenic roles in different cancers, however its role in HNSCC is not known.
High expression of PCAT-1 is observed in different types of cancers, including prostate cancer, colorectal cancer, hepatocellular cancer and gastric cancer.
The long non-coding RNA (lncRNA) prostate cancer-associated ncRNA transcript 1 (PCAT-1) has been shown to promote prostate cancer cell proliferation through c-Myc and is associated with the poor prognosis of CRC patients.
In conclusion, these findings suggested that PCAT-1 accelerated PC cell proliferation, migration, invasion and suppressed apoptosis by up-regulating FSCN1 mediated via miR-145-5p, hinting a potential therapeutic strategy for PC patients.
Prostate cancer-associated transcript 1 (PCAT-1) is a novel lncRNA that promotes cell proliferation in prostate cancer, however, the effect of PCAT‑1 in hepatocellular carcinoma (HCC) remains to be elucidated.
Several nlincRNAs from a prostate cancer associated chromosomal locus, 8q24, are up-regulated in cancer along with other known prostate cancer associated genes including PCAT-1, PVT1, and PCAT-92.
This work establishes a basis for the oncogenic role of PCAT-1 in cancer cell proliferation and is the first study to implicate lncRNAs in the regulation of cMyc in prostate cancer.
Several lncRNAs, such as prostate cancer antigen 3 (PCA3), prostate cancer gene expression marker 1 (PCGEM1), and prostate cancer associated ncRNA transcript 1 (PCAT1), are highly prostate-specific, posing as attractive biomarkers.
Taken together, we propose that PCA-1-DDR-1 signaling is a new important axis involved in malignant potential prostate cancer associated with hormone-refractory status.
Furthermore, because this human counterpart of AlkB exhibits a protective function against alkylation damage in mammalian cells, PCA-1 may also serve as a therapeutic target molecule for prostate cancer.
