ZNF674-AS1 Antagonizes miR-423-3p to Induce G0/G1 Cell Cycle Arrest in Non-small Cell Lung Cancer Cells

Researchers investigated the expression of ZNF674-AS1 in 83 pairs of NSCLC specimens and adjacent noncancerous lung tissues. The clinical significance of ZNF674-AS1 in NSCLC was analyzed. The role of ZNF674-AS1 in NSCLC growth and cell cycle progression was explored.

Pentraxin 3 Acts as a Functional Effector of Akt/NF-κB Signaling to Modulate the Progression and Cisplatin-Resistance in Non-Small Cell Lung Cancer

The biological roles of Pentraxin 3 in NSCLC progression and NSCLC cell resistance to cisplatin were evaluated using enzyme-linked immunosorbent assay, cell count kit-8, colony formation assay, flow cytometry, as well as xenograft tumor assay.

CircVAPA Exerts Oncogenic Property in Non‐Small Cell Lung Cancer by the miR‐876‐5p/WNT5A Axis

RT‐qPCR was used to measure the expression of genes. Actinomycin D and RNase R were employed to examine the stability of circVAPA. CCK‐8, EdU, Transwell, sphere formation assay, and western blot analysis were conducted to examine the changes of NSCLC cells in response to circVAPA knockdown. Luciferase reporter assay was conducted for molecular mechanism.

Alpha-Enolase (ENO1), Identified as an Antigen to Monoclonal Antibody 12C7, Promotes the Self-Renewal and Malignant Phenotype of Lung Cancer Stem Cells by AMPK/mTOR Pathway

Immunofluorescence was used for antigen localization. After targeted antigen purification by electrophoresis and immunoblot, the antigen was identified by LC-MALDI-TOF/TOF mass spectrometry, immunofluorescence, and immunoprecipitation.

The Matrix in Cancer

The author touches on many of the facets of matrix biology in solid cancers, including breast, pancreatic and lung cancer, with the aim of highlighting some of the emerging interactions of the matrix and influences that the matrix has on tumour onset, progression and metastatic dissemination, before summarizing the ongoing work in the field aimed at developing therapies to co-target the matrix in cancer and cancer metastasis.
