Long non-coding RNA TUSC7 suppressed colorectal cancer progression via regulation of miR-23b/PDE7A Axis.

Purpose: Despite advances in our understanding of the roles of the long noncoding RNA (lncRNA) tumor suppressor candidate 7 (TUSC7) in cancer biology, which has been identified to act as a tumor suppressor by regulating cell proliferation, apoptosis, migration, invasion, cell cycle and tumor growth, its function in colorectal cancer remains unknown.

Methods: The expression levels of TUSC7 in colorectal cancer tissues and cell lines were determined, and the biological functions of TUSC7 to cancer progression in colorectal cancer were investigated via correlation analysis of clinical samples, cell viability assay, transwell assay and apoptosis analysis. Further, the molecular regulatory mechanisms of TUSC7 were demonstrated by luciferase reporter assay and western blotting.

Clinical analysis of the impact of sublobectomy on pulmonary function.

The present study investigated and analyzed the clinical impact of sublobectomy on pulmonary functions.Changes in pulmonary function before and after sublobectomy were compared to the changes after lobectomy.Changes in the pulmonary function before and after sublobectomy and lobectomy did not exhibit remarkable differences in long-term effects.
