Tumor suppression in mice lacking GABARAP, an Atg8/LC3 family member implicated in autophagy, is associated with alterations in cytokine secretion and cell death.

GABARAP belongs to an evolutionary highly conserved gene family that has a fundamental role in autophagy. There is ample evidence for a crosstalk between autophagy and apoptosis as well as the immune response. However, the molecular details for these interactions are not fully characterized.

HOPX is methylated and exerts tumour-suppressive function through Ras-induced senescence in human lung cancer.

HOPX acts as a tumour suppressor in various cancers. However, the regulation of HOPX in human lung cancer as well as the mechanism underlying its tumour-suppressive function has not yet been well elucidated. Here we investigated the epigenetic regulation and molecular mechanism by which HOPX exerts growth inhibitory effects.

The p53 target gene desmocollin 3 acts as a novel tumor suppressor through inhibiting EGFR/ERK pathway in human lung cancer.

Desmosomes are intercellular junctions that confer strong cell-cell adhesion. Altered expression of desmocollin 3 (DSC3), a member of the desmosomal cadherin family, was found in various cancers; however, its functional involvement in carcinogenesis has not yet been elucidated. Expression/localization of DSC3 was analyzed by real-time reverse transcription-PCR, western blotting, immunofluorescence and immunohistochemistry.

Molecular cytogenetic characterization of epithelioid hemangioendothelioma.

Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor whose pathological diagnosis can be difficult. In the literature two cases of EHE were found to harbor a balanced t(1;3)(p36.3;q25) translocation, suggesting a characteristic chromosomal rearrangement as cause for the development of EHE.

The diagnostic value of cytokeratin 5/6, 14, 17, and 18 expression in human non-small cell lung cancer.

Objectives: The expression patterns of cytokeratin (CK) filaments in human epithelial neoplasms are complex and distinctive. The aims of this study were to analyze CK expression and to evaluate the diagnostic application of CKs in human non-small cell lung cancer (NSCLC).

Methods: mRNA expression of CK5, CK6, CK14, CK15, CK17, and CK19 was analyzed by Northern blotting.
