Dwarfism is an important agronomic trait in fruit breeding programs. However, the germplasm resources required to generate dwarf pear (Pyrus spp.) varieties are limited.

We found that the conditioned medium (CM) collected from DLC1-overexpressed SW1116 cells inhibited the migration of colon adenocarcinoma cells HCT116 and SW1116, but had no effect on proliferation, which suggested DLC1-mediated secretory components containing a specific inhibitor for colon adenocarcinoma cell migration. Analysis by mass spectrometry identified mesencephalic astrocyte-derived neurotrophic factor (MANF) as a candidate.

Methods: MiR-1254 expression was examined using real-time polymerase chain reaction in CRC and adjacent non-tumorous tissues.
Whether Slit homologue 2 (Slit2) inhibits or promotes tumor cell migration remains controversial, and the role of Slit2‑Roundabout 1 (Robo1) signaling in oral cancer remains to be fully elucidated. The aim of the present study was to investigate the role of Slit2‑Robo1 signaling in the adhesion, invasion and migration of tongue carcinoma cells, and the mechanism by which Slit2‑Robo1 signaling inhibits or promotes tumor cell migration. Tca8113 tongue carcinoma cells were treated with the monoclonal anti‑human Robo1 antibody, R5, to inhibit the Slit2‑Robo1 signaling pathway, with immunoglobulin (Ig)G2b treatment as a negative control.

We aimed at exploring the effect of B7-H4 siRNA on proliferation, invasion, and migration of LOVO cells which expressed B7-H4 notably.

The 6× His-tagged recombinant PACD gene was expressed in Pichia pastoris GS115 and purified with Ni-NTA affinity chromatography. SDS-PAGE analysis and Western blotting revealed that the molecular mass of the purified PACD was 49 kDa.

The full cDNA of the PACD gene has a length of 1408 bp, which contains a complete open reading frame (ORF) of 1329 bp, coding for 442 amino acids. The cDNA of PACD was cloned into the expression plasmid pPIC9K and transformed into Pichia pastoris GS115.

Objective: To investigate aberrant methylation in the promoter of p16 gene in the sediment cells of pleural effusion and evaluate its clinical significance in the differentiating benign and malignant pleural effusion.
Methods: Using methylation-specific PCR (MSP), aberrant promoter methylation of p16 gene was detected in the sedimental cells of pleural effusion samples from 66 patients with pleural effusion.
Results: Of the 66 patients with pleural effusion, 36 had a definite diagnosis of malignant pleural effusion, and the rest were confirmed to have benign pleural effusion.

Objective: To investigate the effect of recombinant panton-valentine leukocidin (rPVL) on the regulation of human alveolar macrophage CD14 and IL-10 and TNF-alpha.
Methods: Human alveolar macrophages (AM) were purified and cultured from bronchoalveolar lavage fluid. Each sample was divided into groups according to different concentrations and exposure times of rPVL.
