Twist1 promotes dendritic cell-mediated antitumor immunity.

Dendritic cells (DCs) play a central role in autoimmunity, immune homeostasis, and presentation of tumor antigens to T cells in order to prime antitumor responses. The number of tumor-infiltrating DCs is associated with survival and prognosis in cancer. Twist1 is a well-known regulator of tumor initiation and promotion, but whether and how DC-derived Twist1 regulates antitumor responses remains poorly understood.

Up-regulated lncRNA XIST contributes to progression of cervical cancer via regulating miR-140-5p and .

Background: The study purpose was to make investigation into the influence of XIST on cervical cancer progression and what's more its potential mechanism.

Methods: The cervical cancer data sets (lncRNA, miRNA, and mRNA) obtained from TCGA were analyzed with the "mixOmics" R package. Then, the expression of XIST, miR-140-5p, and were detected using qRT-PCR and western blot in both tissues and cervical cancer cell lines (Hela and C33A) to verify the bioinformatics analyses results.

Long noncoding RNA OPA-interacting protein 5 antisense transcript 1 upregulated SMAD3 expression to contribute to metastasis of cervical cancer by sponging miR-143-3p.

Objectives: SMAD3 is pivotal in the biology functions of various tumors. This study is aiming to study the relationship among SMAD3, long noncoding RNAs (lncRNAs) OPA-interacting protein 5 antisense transcript 1 (OIP5-AS1), and miR-143-3p, and their effects on cervical cancer.

Methods: In our research, real-time polymerase chain reaction and western blot assay were conducted to detect the expression level of messenger RNA and protein in tumor tissues and cells.

[Research progress in molecular biology of pediatric myelodysplastic syndrome].

Marked differences have been found in molecular characteristics between pediatric and adult myelodysplastic syndrome (MDS) patients. The incidence of gene mutations associated with myeloid malignances in pediatric patients is lower than in adults, while the incidence of aberrant methylation is similar between them. It is also worth noting that novel molecular factors such as mitochondrial DNA mutations may play a role in the pathogenesis of childhood MDS.

Efficient inhibition of human B-cell lymphoma in SCID mice by synergistic antitumor effect of human 4-1BB ligand/anti-CD20 fusion proteins and anti-CD3/anti-CD20 diabodies.

Here we constructed and produced a recombinant human 4-1BB ligand (4-1BBL)/anti-CD20 fusion protein and examined its antitumor activity, alone and in combination with an anti-CD3/anti-CD20 bispecific diabody. The 4-1BBL/anti-CD20 fusion protein retained both the costimulatory activity of 4-1BBL on T cells and the tumor targeting ability of CD20 antibody on B cells. The fusion protein bound as efficiently to 4-1BB- and CD20-positive cells as its respective parental antibodies, and was capable of cross-linking human T lymphocytes and CD20-positive tumor cells.

[Allogeneic stem cell transplantation for 75 cases of acute myeloid leukemia in complete remission: outcome and prognostic analysis].

This study was purposed to evaluate the outcome of patients with acute myeloid leukemia (AML) who received allogeneic hematopoietic stem cell transplantation (allo-HSCT) in complete remission, and to study the prognostic factors. 75 cases of AML in complete remission receiving allo-HSCT from January 2000 to December 2007 were retrospectively analyzed. Major end points of study included overall survival (OS), disease free survival (DFS), relapse rate and transplantation related mortality (TRM).

[Construction and expression of human 4-1BBL/anti-CD20 fusion protein].

Aim: To construct and express human 4-1BBL/anti-CD20 bispecific fusion protein and identify its biological activity.

Methods: PCR and overlapping PCR were used to construct human 4-1BBL/anti-CD20 bispecific fusion protein. DNA sequencing was performed by the terminus of the fusion protein nucleotide.
