Please input one-sentence summary here. 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]. PCGEM1 has been characterised as a high-risk PCa marker and a potential biomarker for neoplasms responsive to chemoprevention by phytosterols [2].
Contents
Annotated Information
Name
PCGEM1: Prostate-specific transcript, LINC00071 (HGNC)
Characteristics
PCGEM1 is located at human chromosome 2q32.3 (HGNC), consists of three exons that comprehends 1603 bp (GenBank).
Function
Over-expression leads to inhibition of apoptosis induced by doxorubicin [3]. t PRNCR1 and PCGEM1 successively 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 [2]. 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].
Disease
prostate cancer
Expression
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 (Srikantan 2000). Cholesterols upregulate the expression of PCGEM1 even in androgen-insensitive prostate cancer cell lines while phytosterols reverse this effect (Ifere 2009). 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 (Petrovics 2004). Low specificity as a biomarker for prostate cancer (14%) (Bialkowska-Hobrzanska 2006).

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 [5].
