OE19 Cell Line human

OE19 cell line has been used to study the effect of microRNA-MiR-193b on autophagy and cell death on these cells. It has also been used to study microRNA-330-5p as a modulator of neoadjuvant chemoradiotherapy sensitivity.

Human Caucasian oesophageal carcinoma

The cell line OE19, also known as JROECL19, was established in 1993 from an adenocarcinoma of gastric cardia/oesophageal gastric junction of a 72 year old male patient. The tumour was identified as pathological stage III (UICC) and showed moderate differentiation. The cell line OE19 expresses HLA-A, -B and -C antigens (MHC class I) constitutively. Treatment with interferon-gamma induced the expression of ICAM-1 (CD54). Expression of HLA-DR (MHC class II) on interferon-gamma addition was only measured in a sub-population of OE19. The cells express epithelial cytokeratins and are tumourigenic in nude mice.The Y chromosome could not be detected in this cell line by short tandem repeat (STR)-PCR analysis when tested at ECACC. It is a known phenomenon that due to the increased genetic instability of cancer cell lines the Y chromosome can be rearranged or lost resulting in lack of detection. The cell line is identical to the source provided by the depositor based on the STR-PCR analysis.

RPMI 1640 + 2 mM Glutamine + 10% Fetal Bovine Serum (FBS).

Split sub-confluent cultures (70-80%) 1:8, i.e., seeding at 1x10,000 cells/cm² using 0.25% trypsin or trypsin/EDTA; 5% CO₂; 37 °C. These cells grow slowly in islands and when resuscitated from frozen it can take up to 7 days to reach 70% confluence.
