Objective: To study the reversal effect of NVP-BEZ235 on doxorubicin resistance in Burkitt lymphoma RAJI cell line.

Methods: The doxorubicin-resistant cell line was induced by treating RAJI cells with a concentration gradient of doxorubicin. The levels of Pgp, p-AKT, and p-mTOR in cells were detected by Western blot.

Objective: To investigate possible mechanism on protien LMP1 expressed by EBV inducing plasmablast differentiation of DLBCL cell via the mTORC1 pathway.

Methods: The expression levels of LMP1 protein, CD38 and the phosphorylation levels of p70S6K in EBV and EBV DLBCL cell lines were detected by Western blot. Cell lines overexpressing gene stablely were constructed and gene was silenced by RNAi.

Background: Diffuse large B-cell lymphoma (DLBCL) is the most common B-cell lymphoma in adults. CDGSH iron sulfur domain 2 (CISD2) is an iron-sulfur protein and plays a critical role of cell proliferation. The aberrant expression of CISD2 is associated with the progression of multiple cancers.

Objective: To investigate the relationship between long non-coding RNA (LncRNA) PANTR1 and imatinib resistance in chronic myeloid leukemia cell line K562 and its mechanism.

Methods: K562 control cells (Control) and K562 imatinib resistant cells (ImR) were cultured. Two siRNA vectors targeting PANTR1 and control vectors were transfected into K562-ImR cells by lentivirus as ImR-siPA#1, ImR-siPA#2 and ImR-siControl cells, respectively.

Objective: To investigate the effect of steadily down-regulating the expression of calreticulin (CALR) on the invasion of natural killer/T-cell lymphoma SNK6 cells, and explore its possible mechanism.

Methods: The sequences of specific short hairpin RNA (shRNA) targeting on human CALR were designed, and were inserted into pLKO.1-puro lentivirus vector, and the reconbinant lentivirus vector was obtained; the lentivirus particles were backed by three-plasmid system and transfected into SNK6 cells, the SNK6 cells stably down-regulating the CALR expression were sercened by puromytain, the CALR-silencing effect was verified by real-time PCR and Western blot.

Objective: To explore the effects of mTOR inhibitor rapamycin on proliferation, cell cycle and apoptosis of Burkitt's lymphoma cell line Raji and CA46 cells and its mechanism, so as to provide the experimental evidence for a therapeutic target of Burkitt's lymphoma.

Methods: 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide(MTT) assay was performed to assess the inhibitory effect of rapamycin on proliferation of Burkitt's lymphoma cell line Raji and CA46 cells. The cell cycle distribution of Raji and CA46 cells was analyzed by flow cytometry with propidium iodide(PI) single staining.

Objective: To investigate the effect of 2 kinds of red blood cells (RBC) on the laboratorial indexes and therapeutic efficacy of patients with autoimmune hemolytic anemia (AIHA).

Methods: The clinical data of 120 patients with AIHA from June 2015 to June 2016 were analyzed retrospectively. These 120 patients were divided into A goup and B group.

The purpose of this study was to investigate the lethal effect of cytotoxic lymphocytes against U266 cells induced by DCs pulsed with multiple myeloma (MM) U266 lysate and transfected with GM-CSF recombinant adenovirus. The cytotoxic lymphocytes against U266 cells were induced by culturing with DCs, which pulsed with MM U266 antigens and transfected with GM-CSF recombinant adenovirus. The effect of cytotoxic lymphocytes against U266 cells were measured by LDH release detection.

Background: Survivin is a rather specific gene in tumor tissue. We transfected dendritic cells (DCs) with recombinant adenovirus (Ad) containing survivin gene and granulocyte-macrophage colony-stimulating factor (GM-CSF) gene and tested the inducing effect of the transfected DCs on cytotoxic T lymphocytes (CTL) to kill leukemic cells.

Methods: After derived from the peripheral, DCs was assayed by mixed leukocyte reaction (MLR) tests.

This study was purposed to investigate the immunological effects of modified dendritic cells (DCs) in inducing cytotoxic T cells (CTLs) effect against lymphoma cells. The DCs were derived from human peripheral blood and transfected with recombined adenovirus vector carrying survivin gene, Western blot was used to detect the expression of survivin, the lactate dehydrogenase (LDH) release test was used to determine the cytotoxicity of CTLs, the mixed lymphocyte reaction (MLR) was used to measure the ability to proleferate allo-lymphocyte by DCs, ELISA was used to assay IL-12 level in supernatant. The results showed that the expression of survivin in transfected dentritic cells was confirmed by Western blot analysis.
