Expression of P120 catenin mRNA in Non-Hodgkin's lymphoma cell lines.

To investigate p120 catenin mRNA expression in Non-Hodgkin's lymphoma (NHL) cell lines (U937, Raji, Jurkat and Molt4) and normal lymphocytes and explore the relationship between p120 catenin and Non-Hodgkins lymphoma, total RNA sample was extracted by using TRIzol and reversely transcripted into cDNA. Polymerase chain reaction was performed to detect mRNA expression of p120 catenin in NHL cell lines U937, Raji, Jurkat and Molt4. Normal lymphocytes were used as control. It was found expressions of p120 catenin 1A and 3A mRNA were high in above-mentioned NHL cell lines, but neither p120 catenin 1A nor 3A was found in normal lymphocytes as shown by RT-PCR. It is concluded that both P120ctn1A and P120ctn3A mRNA transcripts were found in all NHL cell lines U937, Raji, Jurkat and Molt4 but they don't exist in normal lymphocytes, suggesting p120ctn possibly is of importance in diagnosis and therapy of lymphoma.
