[Construction and expression of the recombinant plasmid containing BddhFVIII in HepG2 cells].

Objective: To get stable cell line expressing B domain-deleted human FVIII (BDDhFVIII) by constructing the eukaryotic expression plasmid.

Methods: Eukaryotic expression plasmid containing BDDhFVIII was constructed and transfected into HepG2 cells via electroporation. The expression and purification of the target protein was detected by Western blot.

[Expression of ADAR1 isoforms in murine acute T-ALL leukemia model].

This study was purposed to investigate the expression of ADAR1 isoforms of P110 and P150 during the development of murine leukemia. A Notch1 over-expressing murine T cell acute lymphoblastic leukemia model was used to study the expression of ADAR1. BMMNC were isolated at different stages of disease and CD45.

Abnormal expression of ADAR1 isoforms in Chinese pediatric acute leukemias.

The posttranscriptional RNA editing by the type 1 adenosine deaminase acting on RNAs (ADAR1), expressed as p110 and p150 isoforms, is important for both physiological and pathological processes. Their expression and significance in leukemias remain unknown. Here, we investigated the expression of ADAR1 in Chinese pediatric acute leukemias by real-time PCR and Western blot.

The hyposensitive N187D P2X7 mutant promotes malignant progression in nude mice.

Nucleotides are new players in the intercellular communication network. P2X7 is a member of the P2X family of receptors, which are ATP-gated plasma membrane ion channels with diverse biological functions. Abnormal expression and dysfunction of P2X7 have been reported in leukemias.

Abnormal expression of P2X family receptors in Chinese pediatric acute leukemias.

Nucleotides are new players in intercellular communication network. P2X family receptors are ATP-gated plasma membrane ion channels with diverse biological functions. Their distribution patterns and significance in pediatric leukemias have not been established.

A special linker between macrophage and hematopoietic malignant cells: membrane form of macrophage colony-stimulating factor.

The membrane form of macrophage colony-stimulating factor (mM-CSF) is an alternative splicing variant of this cytokine. Although its high expression was detected in hematopoietic malignancies, its physiologic and pathologic roles in hematopoietic system have not been established. In this report, stable transfectant clones expressing mM-CSF (Namalwa-M and Ramos-M) were obtained, which showed reduced proliferation potential in vitro.
