PCGEM1 (Prostate cancer gene expression marker 1) is a long non-coding RNA (lncRNA) overexpressed in prostate cancer (PCa) cells that promotes PCa initiation and progression and protects against chemotherapy-induced apoptosis [1].

Annotated Information


PCGEM1: Prostate-specific transcript, LINC00071 (HGNC)


PCGEM1 is located at human chromosome 2q32.3 and spannining the genomic region of spanning the 27054 bp, consists of three exons that comprehends 1603 bp (GenBank) [2].


PCGEM1 regulates expression of metabolic enzymes in multiple pathways.Expression of the metabolic genes in PCGEM1 knockdown LNCaP cell was examined by qRT-PCR. Positive and negative values indicate up and down-regulation compared with control cell, respectively.[3]

PCGEM1 regulates prostate cancer cell growth, tumor metabolism and proliferation of human synoviocytes [1][3][4][5].

PCGEM1 regulates metabolism at a transcriptional level that affects multiple metabolic pathways, including glucose and glutamine metabolism, the pentose phosphate pathway, nucleotide and fatty acid biosynthesis, and the tricarboxylic acid cycle. The PCGEM1-mediated gene regulation takes place in part through AR activation, but predominantly through c-Myc activation, regardless of hormone or AR status. PCGEM1 binds directly to target promoters, physically interacts with c-Myc, promotes chromatin recruitment of c-Myc, and enhances its transactivation activity [3].

Over-expression of PCGEM1 leads to inhibition of apoptosis induced by doxorubicin [6]. PCGEM1 and PRNCR1 interact with the androgen receptor (AR) bound at DNA-enhancer regions in a ligand-dependent fashion and facilitate the chromosomal looping between AR-bound enhancers and the promoter sequences of androgen-responsive genes [4].

Reciprocal regulation of PCGEM1 and miR-145 promote proliferation of LNCaP prostate cancer cells and nu/nu PCa tumor growth. Both downregulation of a tumor-promoting long noncoding RNA PCGEM1 or overexpression of the tumor suppressor miR-145 reduced the proliferation and invasive capacity of prostate cancer cells in vitro and in vivo [1].

PCGEM1 is involved in the hyperplasia of the synovial lining, a common characteristic of Osteoarthritic (OA). Exogenous overexpression of PCGEM1 inhibited apoptosis, induced autophagy, and stimulated the proliferation of human synoviocytes. The increased expression of PCGEM1 in human synoviocytes also suppressed the expression of miR-770. Transfection of the miR-770 precursor resulted in reduced proliferation, and induced apoptosis of human synoviocytes [5].


PCGEM1, was expressed exclusively in human prostate tissue, was dramatically upregulated in PCa tissues compared with normal prostate tissues. Prostate tissue-specific and prostate cancer-associated [2]. Cholesterols upregulate the expression of PCGEM1 even in androgen-insensitive prostate cancer cell lines while phytosterols reverse this effect [7]. PCGEM1 overexpression in LNCaP and in NIH3T3 cells promotes cell proliferation and a dramatic increase in colony formation, suggesting a biological role of PCGEM1 in cell growth regulation [8]. Overexpression of PCGEM1 stimulates proliferation andInhibits apoptosis of synoviocytes [5].

Allelic Information and Variation

PCGEM1 polymorphisms may contribute to PCa risk in Chinese men. Men carrying single nucleotide polymorphisms (SNPs) of PCGEM1, i.e. rs6434568 AC and rs16834898 AC, had a lower PCa risk in comparison to the ones harboring CC and AA genotypes, respectively [10].
