Annotated Information

Approved Symbol

EPIC1

Approved Name

EPIC1: Epigenetically induced lncRNA1 [1] LOC284930 (GenBank)

Characteristics

EPIC1 is an intergenic 1815 bp long non-coding RNA, located on chromosome chr22:q13.31, consisting nine exons (GenBank). CpG island is present downstream of EPIC1 gene transcription start site.EPIC1 RNA is predominately located in the nucleus [1].

Function

EPIC1 has beed reported to interact with MYC and regulate cell growth [1][2] and drug-resistance [3][4] by MYC pathway. EPIC1 promotes breast tumorigenesis through regulating cancer cell-cycle progression [1]. EPIC1 interact with MYC and directly regulates the expression of MYC targets through their promoter regions [1]. EPIC1 may regulate iBET (Bromodomain and Extra-Terminal inhibitors) resistance through increasing MYC protein’s transcriptional activity [3]. EPIC1 knockdown in MCF-7 cells resulted in the upregulation of 317 genes and downregulation of 488 genes, but had little effect on the expression of MYC [1]. EPIC1 promotes human lung cancer cell growth by MYC pathway [2]. EPIC1 protects human osteoblasts from dexamethasone (Dex) induced cell death probably through MYC pathway [4].

Regulation

EPIC1 is directly controlled by DNA methylation at the CpG islands in its promoter region [1].

Diseases

  • Breast cancer [1]
  • Endometrial cancer [1]
  • Lung cancer [2]

Expression

EPIC1 is overexpressed in luminal breast cancer cell lines (e.g., BT-474, MB361, MCF-7, ZR-75-1, and T-47D), along with ovarian cancer (A2780cis and OVCAR-4), pancreatic cancer (BxPC-3 and PANC-1), prostate cancer (PC-3), and leukemia (K562) cell lines [1]. EPIC1 is upregulated in the necrotic femoral head tissues of Dexamethasone(Dex) taking patients [2].
