CCAAT/enhancer binding protein alpha gene (CEBPA) is an important transcription factor in maintenance of differentiation of granulocyte series of hematopoietic system. It plays a key role in regulating cell proliferation and differentiation. CEBPA mutation easily occurs in M1 and M2 type of acute myeloid leukemia, about 5%-14% in adult acute myeloid leukemia and 7.9% in children with acute myeloid leukemia. At present, domestic CEBPA mutation research is far less than abroad. This review focuses on the structual characteristics and detection method of CEBPA, CEBPA clinical features, the effect of CEBPA mutation on the prognosis of patients and the choice of treatment.

This study was aimed to explore the clinical characteristics and therapeutic efficacy of normal karyotype AML patients with CEBPA mutations. Fifty-five de novo AML patients with normal karyotype were retrospectively analyzed with regard to frequency of CEBPA mutation, clinical characteristics and therapeutic response. The results showed that CEBPA mutation was detected in 20 patients (36.4%), among them 17 cases displayed double mutations, three cases were with single mutation. The clinical characteristics of patients with CEBPA mutation displayed as follows: 75% of AML patients with CEBPA mutation were AML-M1 and AML-M2, the hemoglobin level at newly diagnosis was higher and the platelet count at newly diagnosis time was lower than those of AML patients without CEBPA mutation [(98.30 ± 20.33) g/L vs (81.69 ± 23.74) g/L (P < 0.05); and (33.30 ± 38.27) ×10(9)/L vs (64.79 ± 61.60) ×10(9)/L (P < 0.05)]. The leukemic cells highly expressed CD7 and CD34. The therapeutic efficacy of 1 cycle for AML patients with CEBPA mutation was satisfactory (72.2%), was higher than that of patients without CEBPA mutation(68.6%), but there was no statistical significance (P > 0.05). It is concluded that AML with CEBPA mutation is more observed in AML-M1 and AML-M2, and accompanies by high level of hemoglobin and lower platelet count, expression of CD7 and CD34. Early-term therapeutic efficacy is satisfactory. The frequency of CEBPA mutation may be higher in Chinese patients with AML compared with that reported in Western world.

BACKGROUND:
The hepatitis B virus (HBV) vaccine has been efficiently used for decades. However, hepatocellular carcinoma caused by HBV is still prevalent globally. We previously reported that interferon (IFN)-induced tripartite motif-containing 25 (TRIM25) inhibited HBV replication by increasing the IFN expression, and this study aimed to further clarify the anti-HBV mechanism of TRIM25.
METHODS:
The TRIM25-mediated degradation of hepatitis B virus X (HBx) protein was determined by detecting the expression of HBx in TRIM25-overexpressed or knocked-out HepG2 or HepG2-NTCP cells via Western blotting. Co-immunoprecipitation was performed to confirm the interaction between TRIM25 and HBx, and colocalization of TRIM25 and HBx was identified via immunofluorescence; HBV e-antigen and HBV surface antigen were qualified by using an enzyme-linked immunosorbent assay (ELISA) kit from Kehua Biotech. TRIM25 mRNA, pregenomic RNA (pgRNA), and HBV DNA were detected by quantitative real-time polymerase chain reaction. The retinoic acid-inducible gene I (RIG-I) and pgRNA interaction was verified by RNA-binding protein immunoprecipitation assay.
RESULTS:
We found that TRIM25 promoted HBx degradation, and confirmed that TRIM25 could enhance the K90-site ubiquitination of HBx as well as promote HBx degradation by the proteasome pathway. Interestingly, apart from the Really Interesting New Gene (RING) domain, the SPRY domain of TRIM25 was also indispensable for HBx degradation. In addition, we found that the expression of TRIM25 increased the recognition of HBV pgRNA by interacting with RIG-I, which further increased the IFN production, and SPRY, but not the RING domain is critical in this process.
CONCLUSIONS
The study found that TRIM25 interacted with HBx and promoted HBx-K90-site ubiquitination, which led to HBx degradation. On the other hand, TRIM25 may function as an adaptor, which enhanced the recognition of pgRNA by RIG-I, thereby further promoting IFN production. Our study can contribute to a better understanding of host-virus interaction.

This study was aimed to explore the anti-leukemic effect of scutellaria extract SBX in human leukemia cell lines and its mechanism. The leukemia cell lines, including HL-60, NB4, U937, K562 and Jurkat, were cultured in vitro and proliferative inhibition of these cell lines was detected by CellTiter-Glo Luminescent Cell Viability Assay in order to screen the most sensitive cell line. The effect of SBX on cell cycle was analyzed by flow cytometry and the protein expressions determined by Protein Pathway Array respectively. The results indicated that SBX (10 - 200 µmol/L, for 72 h) significantly inhibited the proliferation of different leukemia cell lines in a dose-dependent manner (r value was 0.86, 0.88, 0.95, 0.94, 0.96, respectively), the HL-60 was the most sensitive cell line. Flow cytometric analysis showed that SBX (50, 10 µmol/L, for 48 h) arrested HL-60 cells in the G(0)/G(1) phase. In addition, protein expression of p-PKC α/βII, p-p38, Cdc25B, XIAP of HL-60 cells increased, and p-AKT, p-SAPK/JNK, Notch4, Cdk4, Cdc2, cyclin E, Akt, Bcl-2, Bax, cdc42, TNF-α, p27, CaMKKa decreased after exposure to SBX (50 µmol/L, for 48 h). It is concluded that SBX can inhibit the proliferation of different leukemia cell lines, and HL-60 is a sensitive cell line. SBX significantly influences EGFR, Ras/Raf/MAPK and Notch signaling pathway, through which effects the expression of cell cycle-related proteins resulting in arrest of HL-60 cells in G(0)/G(1).
