Background Studies have shown that E3 ubiquitin ligase CBLL1 plays multiple roles in development and tumorigenesis. CBLL1 is over-expressed in colon cancer and associated with cancer cell proliferation. While, the overexpression of CBLL1 inhibited the estrogenic dependent cell proliferation and migration in ER alpha dependent breast cancer cell MCF-7. Methods We used an immunohistochemical method to detect CBLL1 expression in human NSCLC and corresponding normal lung tissues and analyzed its relationship with clinicopathological parameters. Moreover, we investigated the role of CBLL1 in NSCLC cell behavior by inhibiting its expression in A549 and H1299 cells. Results In this study, we found that CBLL1 was frequently upregulated in non-small lung cancer (NSCLC) tissues compared to the adjacent nontumor tissues. We found that the high expression of CBLL1 was associated with the tumor size in NSCLC tissues. It has been recently reported that CBLL1 promotes cell proliferation and invasion in A549 and H460 cells. Our results confirmed that CBLL1 promoted the proliferation by promoting G1/S cell cycle transition in NSCLCs cells. Moreover, CBLL1 knockdown inhibited cell invasion via increased E-cadherin protein expression, and decreased expression of MMP2 and MMP9 in NSCLC cell lines. The protein expression of E-cadherin was increased after CBLL1 depletion while the E-cadherin mRNA was not affected after knockdown of the endogenous CBLL1. Conclusion These results provide important insights for using CBLL1 as an oncogenic marker gene in the development and progression of non-small cell lung cancer.

Turbulent flow and reactive pollutant dispersion in the convective boundary layer (CBL) over flat and urban-like surfaces are investigated using a large-eddy simulation model with NO-NO2-O-3 chemistry, with the urban-like surface represented by a block array. The CBL over a flat surface with and without ambient flow (FW and FNW cases, respectively) and the CBL over a block array with and without ambient flow (BW and BNW cases, respectively) are simulated. Wind shear in the entrainment zone increases the turbulence intensity and enhances the heat exchange in the entrainment zone. The urban-like surface induces greater wind shear in the entrainment zone, thus the largest turbulence intensity and heat exchange are found in the BW case. High NO concentration appears in updraft regions, whereas high O-3 concentration appears in downdraft regions. The segregation of NO and O-3 reduces the O-3 decomposition in the CBL. The magnitude of the vertical gradients of NO, NO2, and O-3 concentrations in the entrainment zone is smallest in the BW case, indicating that the largest reactive pollutant exchange occurs in the BW case. It seems that the greater wind shear in the entrainment zone induced by the urban-like surface also enhances the reactive pollutant exchange in the entrainment zone. The magnitude of the O-3 production rate in the entrainment zone is large due to the mixing of mixed-layer air with air in the entrainment zone, especially around updraft regions. Since the segregation of NO and O-3 interrupts the O-3 decomposition, the turbulent component of the O-3 production rate is generally positive in the CBL. The reduction of the O-3 decomposition due to the segregation in the entrainment zone is smallest in the BW case. The effects of segregation on the chemical reactions are reduced due to the strengthened turbulent motions in the BW case.
