Background: Expression of E2F transcription factor 2 (E2F2), a transcription factor related to the cell cycle, is abnormally high in rheumatoid arthritis synovial fibroblasts (RASFs). Deregulated expression of E2F2 leads to abnormal production of proinflammatory cytokines, such as interleukin (IL)-1α, IL-1β, and tumor necrosis factor (TNF)-α in RASFs. However, the underlying mechanism by which E2F2 regulates expression of IL-1α, IL-1β, and TNF-α has not been fully elucidated.

To investigate the role and mechnism of E2F2 in RA, expression of E2F2 in synovial tissue was detected. Proliferation, invasion, and secretion of inflammatory cytokines were measured after E2F2 was knocked-down in RASFs by siRNA transfection.

To observe the effect of polydatin on proliferation and apoptosis of cervical cancer HeLa cells and explore its possible mechanism. The growth inhibitory effect was detected with MTT assay. After HeLa cells were treated with different concentrations (50, 100, 150 μmol•L⁻¹) of polydatin, MTT assay was used to detect the inhibitory effect of polydatin on proliferation of HeLa cells; Acridine orange/ethidium bromide staining was used for morphological changes in apoptotic HeLa cells; Annexin/propidium iodide staining was applied to detect HeLa cell apoptotic rate.

To observe the biological characteristic and the prognoses in patients with acute erythroleukemia (AEL). The results of 167 patients with newly diagnosed AEL, from January 2004 and June 2014 in the department of Hematology, Shandong Province Chinese Medicine Hospital, were reviewed by morphology, immunology, cytogenetics, molecular biology. Flow cytometry analysis indicated that CD13 (96.

MDR1 gene polymorphisms may have an impact on the expression and function of P-gp, thereby influencing the response to chemotherapy.
Objectives: To investigate whether the MDR1 2677 and 3435 genotypes are associated with the sensitivity of non-small-cell lung cancer (NSCLC) to docetaxel.
Background: The polymorphisms of genes participate in metabolism and transport, and therefore may have an impact on the response to vinorelbine.
Objectives: To investigate whether genotypes of CYP3A5, MDR1 and cyclooxygenase-2 (COX-2) are associated with the response to vinorelbine in non-small cell lung cancers (NSCLC).
Methods: We determined the genotypes of CYP3A5(*3), MDR1 (2677G-->T at exon 21 and 3435C-->T at exon 26 and their haplotypes) and COX-2 (-1195G-->A) polymorphisms by PCR-RFLP and chemotherapy response in 69 Chinese Han patients with NSCLC who received a combination chemotherapy of vinorelbine-cisplatin (VC).
CYP2C19*2(G681A), CYP2C19*3(G636A), CYP2D6*4(C188T), CYP2D6*2(C2938T, G4268C), CYP3AP1*3- G44A and CYP3A5*3(A22893G) are the most common polymorphisms detected among Chinese that may influence the efficacy of vinorelbine-based therapies to treat non-small-cell lung cancer (NSCLC). We detected the genotypes of these polymorphisms by PCR-RFLP in 59 patients with NSCLC and assessed their responses to vinorelbine. CYP2D6*4(C188T), CYP3AP1*3 (G -44 A) and CYP3A5*3 were found to be associated with response to vinorelbine.
