SPIN1 accelerates tumorigenesis and confers radioresistance in non-small cell lung cancer by orchestrating the FOXO3a/FOXM1 axis.

Despite the importance of radiation therapy as a nonsurgical treatment for non-small cell lung cancer (NSCLC), radiation resistance has always been a concern because of poor patient response and outcomes. Therefore, it is crucial to identify novel targets to increase the effectiveness of radiotherapy and investigate the mechanisms underlying radioresistance. Previously, we demonstrated that Spindlin 1 (SPIN1) was related to tumour initiation and progression.

Tripartite motif 31 drives gastric cancer cell proliferation and invasion through activating the Wnt/β-catenin pathway by regulating Axin1 protein stability.

Mounting evidence has proposed the importance of the Wnt/β-catenin pathway and tripartite motif 31 (TRIM31) in certain malignancies. Our research aimed to clarify the correlation between aberrant TRIM31 expression and the Wnt/β-catenin pathway during gastric cancer (GC) oncogenesis and development. TRIM31 was drastically elevated in GC tissues and was closely associated with aggressive clinical outcomes and poor prognosis.

WWP2 drives the progression of gastric cancer by facilitating the ubiquitination and degradation of LATS1 protein.

Background: Large tumor suppressor kinase 1 (LATS1), one of the predominant components of the Hippo pathway, has been characterized as a key player controlling the proliferation and invasion of cancer cells, including gastric cancer (GC) cells. However, the mechanism by which the functional stability of LATS1 is modulated has yet to be elucidated.

Methods: Online prediction tools, immunohistochemistry and western blotting assays were used to explore the expression of WW domain-containing E3 ubiquitin ligase 2 (WWP2) in GC cells and tissues.
