DNA/RNA

Note

The MYEOV gene was originally isolated by the application of the NIH/3T3 tumorigenicity assay with DNA from a gastric carcinoma. The chromosomal region 11q13 is frequently associated with genetic rearrangements in a large number of human malignancies, including B-cell malignancies and overexpression of MYEOV is frequently observed in breast tumors and oral, esophageal squamous cell carcinomas and multiple myeloma. The presence of functional domains such as RNP-1 (motif typical of RNA binding protein) and the studies of the short hydrophobic regions and of the C-terminal leucine/isoleucine tail showed that MYEOV might be directed to the membrane. MYEOV small interfering RNA (siRNA) decreased proliferation of gastric cancer cells, colon cancer cell lines and multiple myeloma cells in vitro.
Atlas Image

Description

2 exons; 3,5 kb transcript represents unspliced mRNA.

Transcription

Main transcript 2,8 kb (broad band because of alternative splice products); minor transcript 3,5 kb; coding sequence 313 or 255 amino acids. In normal tissues hardly any expression detectable. High expression in a subset of multiple myeloma cell lines with a t(11;14)(q13;q32) and in breast tumors and esophageal squamous cell carcinomas with or without 11q13 amplification.

Pseudogene

No pseudogenes have been reported for MYEOV.

Proteins

Description

313 or 255 amino acids; contains one RNP-1 motif and 6 regions that might function as a transmembrane domain. Leucine-rich stretch at C-terminal.

Expression

5 UTR inhibits efficient translation of the protein.

Localisation

In endoplasmic reticulum and mitochondria.

Homology

No known homology.

Implicated in

Entity name
t(11;14)(q13;q32)
Disease
Subset of multiple myeloma cell lines with t(11;14)(q13;q32).
Cytogenetics
MYEOV overexpression due to juxtaposition to the 5 enhancer or the most telomeric 3 enhancer of the immunoglobulin heavy chain (IgH).
Entity name
11q13 amplification and/or overexpression
Disease
Breast cancer; esophageal squamous cell carcinomas.
Prognosis
MYEOV DNA amplification correlated with estrogen and progesterone receptor-positive cancer, invasive lobular carcinoma type and axillary nodal involvement. In contrast to Cyclin D1 amplification, no association with disease outcome could be found.
Entity name
Multiple myeloma
Prognosis
In a cohort of 171 myeloma patients, patients with MYEOVabsent MMC have an increased event-free survival compared to patients with MYEOVpresent MMC, after high-dose therapy and stem cell transplantation and a trend for increased overall survival. In a Cox proportional hazard model, MYEOV expression in MMC is predictive for event-free survival for patients independently of International Staging System stage, t(4;14) translocation, albumin, or B2M serum levels. In a second independent cohort of 208 patients (LR-TT3, from the University of Arkansas for Medical Sciences (Little Rock, AR, USA)), MYEOV had a "present" call in MMCs of 73% of patients. Patients with MYEOVabsent MMCs had a significant better overall survival in the LR-TT3 cohort.
Oncogenesis
In a cohort of 171 patients, MMC of 79% of the patients with newly diagnosed MM express MYEOV gene. A treatment with 5-aza-2-deoxycytidine of 2 MYEOVabsent myeloma cell lines induced MYEOV expression without affecting that in the MYEOVpresent myeloma cells. MYEOV siRNA did not significantly induce apoptosis in myeloma cell lines, but it blocked the cell cycle entry into the S-phase.
Entity name
Colon cancer
Oncogenesis
Knockout of MYEOV RNA (siRNA) has been shown to decrease proliferation of colon cancer cell lines in vitro. Furthermore, in colon cancer, MYEOV stimulates colorectal cancer cell migration in vitro. MYEOV expression is enhanced by PGE2 treatment in colorectal cancer cells.
Entity name
Gastric cancer
Oncogenesis
Knockout of MYEOV RNA (siRNA) has been shown to decrease proliferation and invasion of gastric cancer cells in vitro.
Entity name
Neuroblastoma
Oncogenesis
MYEOV is a candidate gene target in neuroblastoma that was identified by chromosomal gain 11q13 through SNP analysis. MYEOV expression was analyzed in 55 neuroblastoma samples including 25 cell lines. MYEOV was shown to be upregulated in 11 out of 25 neuroblastoma cell lines and 7 out of 20 fresh tumors. Knockout of MYEOV RNA (siRNA) has been shown to decrease proliferation of neuroblastoma cell line in vitro.
Entity name
Oral squamous cell carcinoma
Oncogenesis
Gain of 11q13 was significantly associated with cervical lymph node metastasis in oral squamous cell carcinoma (54 patients included in the study). Copy number amplification of MYEOV is associated with cervical lymph node metastasis in oral squamous cell carcinoma. Lymph node metastasis is associated with a significant decrease of 5-years survival in oral squamous cell carcinoma.
