METTL3-mediated TIM1 promotes macrophage M1 polarization and inflammation through IGF2BP2-dependent manner.

Macrophage polarization and inflammation may play an important role in the development of sepsis. T-cell immunoglobulin mucin 1 (TIM1) has been demonstrated to promote macrophage inflammatory responses. However, whether TIM1 regulates macrophage polarization and inflammation to affect sepsis development remains unclear.

Efficacy and safety of combined doxofylline and salbutamol in treatment of acute exacerbation of chronic obstructive pulmonary disease.

Objective: The aim of this study was to investigate the efficacy and safety of combined doxofylline and salbutamol in the treatment of acute exacerbation of chronic obstructive pulmonary disease.

Methods: A total of 68 acute exacerbation of chronic obstructive pulmonary disease patients were randomly divided into control group (34 cases) and experimental group (34 cases), who received the doxofylline treatment and combined doxofylline and salbutamol treatment for 1 week, respectively. During the treatment, the remission time of typical respiratory manifestations was recorded, and the adverse reactions were observed.

Interleukin-18 promotes the antitumor ability of natural killer cells in colorectal cancer via the miR-574-3p/TGF-β1 axis.

Interleukin (IL)-18 has a clear antitumor effect; however, its mechanisms of action are not understood in patients with colorectal cancer (CRC). Here, we investigated the potential mechanism of IL-18 in CRC. The results showed that IL-18 treatment alone had no effect on HCT116 cells apoptosis, whereas IL-18 in the presence of natural killer (NK) cells resulted in apoptosis and inhibition of cells proliferation in vitro.

[Effect of adenovirus-mediated ING4 and IL-24 co-expression on chemosensitivity to human lung adenocarcinoma in vitro and in vivo].

To study the chemosensitivity and the mechanisms of recombinant adenovirus vector expressing ING4 and IL-24 (Ad-ING4-IL-24) on lung adenocarcinoma in vitro and in vivo, the expression of ING4 and IL-24 in A549 cells was detected by RT-PCR and Western blotting. The growth inhibition, apoptosis rate and apoptosis body were measured by MTT, flow cytometry and Hoechst staining respectively. For in vivo study, we first established the A549 tumor model by grafting A549 cells in athymic nude mice; and then injected Ad-ING4-IL-24 into the tumors.
