Expression Levels of HES1, C-MYC and NF-kB in Peripheral Blood of Patients with T Cell Acute Lymphoblastic Leukemia and Their Significance

Abstract

To analyze and investigate the expression levels of HES1, C-MYC and NF-kB in peripheral blood of patients with T cell acute lymphoblastic leukemia (T-ALL) and their significance. Sixty patients with T-ALL and 60 patients with acute myelogenous leukemia (AML) diagnosed in our hospital from June 2012 to March 2015 were enrolled in T-ALL group and AML group, respectively. Another 30 healthy people were enrolled in the control group. Peripheral blood was collected to detect the expression levels of HES1, C-MYC and NF-kB by RT-PCR. The general data and the expression of HES1, C-MYC and NF-kB in peripheral blood were compared among the patients with different type of leukemia, cytogenetical types and different prognosis. There was no significant difference in baseline data, such as age and sex among the 3 groups (P＞0.05). The Hb level, WBC and Plt count, BM blast cell ratio in T-ALL and AML groups all were significantly higher than those in control group (P＜0.01), but there were no statistical difference in above-mentioned indicators between T-ALL and AML groups (P＞0.05). The expression levels of HES1, C-MYC and NF-kB in peripheral blood among 3 groups were significantly differenct (P＜0.01), the expressions levels of HES1, C-MYC and NF-kB in T-ALL and AML groups were significantly higher than those in control were significantly group (P＜0.01), moreover, the expression levels of above-mentional indicators in T-ALL groups were significantly higher than than those in AML group (P＜0.01). The expression levels of HES1, C-MYC and NF-kB iin T-ALL patients with poor prognosis were significantly higher than those in T-ALL patients with favorable prognosis (P＜0.01); the expression levels of HES1, C-MYC and NF-kB in peripheral blood of patients with different theraptic efficacy were follow: complete remission group＜partial remission group＜no remission group (P＜0.01). The HES1, C-MYC and NF-kB are highly expressed in peripheral blood of the patients with T-ALL, moreover, the expression levels maybe different, because of the cytogenetic, and theraptic efficacy.
