The study was aimed to analyse the effects of miR-128 on the proliferation and apoptosis of lung cancer cells of non-small cell by regulating RECK. The expression of miR-128 in non-small cell lung cancer (NSCLC) and its paracancerours tissues was analyzed by sequencing. miR-128 expression level in NSCLC and its paracancerours tissues was detected by qPCR. We over expressed miR-128 by mimics in A549 NSCLC cell line. Establish blank and negative control group. miR-128 and RECK expression level in each group was detected by qPCR. Use MTT assay to test the proliferation ability of each group. The apoptosis level and the level of ROS in each group were tested by hoechst 33258. The expression level of apoptosis-related protein and p38 NF- B signal pathway-related protein in each group was tested by Western blot. The results of sequencing and qPCR showed that compared with the blank control group, the expression level of miR-128 mRNA was significantly higher in the adjacent tissues than in the adjacent tissues (P < 0 05). The expression levels of miR128 mRNA and RECK mRNA in the overexpression group were significantly increased (P

A new method for targeting lung infections is of great interest using biodegradable nanoparticles. In this study, bergenin-loaded BSA NPs were developed against lung injury. Briefly, bergenin-loaded bovine serum albumin nanoparticles (BG@BSA NPs) were synthesized and characterized. HPLC recorded the major peak of bergenin. UV–Vis spectra had an absorbance at 376 nm. XRD revealed the presence of crystalline particles. FTIR confirmed the occurrence of functionalized molecules in the synthesized NPs. The particles were highly stable with a net negative charge of − 24.2. The morphology of NPs was determined by SEM and TEM. The mean particle size was 124.26 nm. The production of NO by NR8383 cells was decreased by BG@BSA NPs. Also, in mice, lipopolysaccharide-mediated acute lung inflammation was induced. BG@BSA NPs reduced macrophages and neutrophils in BALF and remarkably enhanced wet weight-to-dry weight (W/D) ratios and myeloperoxidase (MPO) activity. Further, BG@BSA NPs inhibited the production of inflammatory cells as well as tumor necrosis factor. The histopathological studies revealed that the damage and neutrophil infiltration were greatly inhibited by BG@BSA NPs. This indicates that BG@BSA NPs may be used to treat lung infections. Therefore, this study has given new insight into producing an active drug for the treatment of lung-associated diseases in the future.
