Single-cell analyzing of tumor microenvironment and cell adhesion between early and late-stage lung cancer.

Lung adenocarcinoma (LUAD) is a highly heterogeneous disease that threaten human life with serious incidence and high mortality. High heterogeneity of tumor microenvironment (TME) was reported in multiple studies. However, the factor of controlling the tumor migration progression between eary and late-stage LUAD is still not fully understood.

miR-31-5p modulates cell progression in lung adenocarcinoma through TNS1/p53 axis.

Objective: To clarify the modulatory mechanism of miR-31-5p in lung adenocarcinoma (LUAD) progression in vivo and in vitro.

Methods: The Cancer Genome Atlas (TCGA) database was employed to access LUAD-related miRNA and mRNA expression data. Downstream targets of miR-31-5p were predicted by public databases.

Lysyl Oxidase Gene G473A Polymorphism and Cigarette Smoking in Association with a High Risk of Lung and Colorectal Cancers in a North Chinese Population.

The relationship among the lysyl oxidase (LOX) G473A single nucleotide polymorphism (SNP), cigarette smoking and lung, colorectal, colon and rectum cancer susceptibility was studied in 200 cases of lung cancer, 335 cases of colorectal cancer including 130 cases of colon cancer and 205 cases of rectum cancer, and 335 healthy people in Tangshan, China. Peripheral blood DNA samples were collected, DNA sequencing and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) performed, followed by multivariate logistic regression analysis. In comparison to LOX473GG genotype carriers, individuals with LOX473AA exhibited a higher susceptibility to lung, colon-rectum, colon, and rectum cancers with OR values amounting to 3.

A small interfering ABCE1-targeting RNA inhibits the proliferation and invasiveness of small cell lung cancer.

Small cell lung cancer (SCLC) is a highly aggressive lung neoplasm. To study the pathogenesis of SCLC, we investigated roles of ABCE1, a member of the ATP-binding cassette (ABC) superfamily, in the development of small cell lung cancer. RNA interference was used to knock down ABCE1 expression in human small cell lung cancer cell lines (NCI-H446).
