Special Issue Information

Dear Colleagues,

In most cases, cancer-related mortality is attributed to the effects and complications of cancer cell metastasis and not the primary tumor itself. Metastasis is a complex process during which cells initially dissociate from the original tumor, then migrate and invade through the extracellular matrix and surrounding tissues. Subsequently, they disseminate through the circulation to distant sites in the body, where they form metastatic tumors. Although extensive research has been conducted in this field, several questions remain unanswered. Taking advantage of new developments in cell culture systems and models, as well as animal models, efforts have been undertaken to mimic the metastatic process in vitro and in vivo in order to improve its study, understand it and, ultimately, reverse it. This Special Issue aims to present these advances in cancer cell metastasis-related research involving both in vitro and in vivo approaches and models, providing a more thorough understanding of cancer cell metastasis and cellular and molecular events and mechanisms defining it. The studies may involve culture models and assays developed in two or three dimensions (3D) in any type of cancer cell lines, animal models, xenografts, and any related molecular signaling pathways that regulate cancer metastasis, cell adhesion, migration, invasion and proliferation.

Tspan14 is a transmembrane protein of the tetraspanin (Tspan) protein family. Different members of the Tspan family can promote or suppress tumor progression. The exact role of Tspan14 in tumor cells is unknown. Earlier, mutational inactivation of the TSPAN14 gene has been proposed to coincide with a low survival rate in NSCLC patients. This study aimed to investigate the correlation of TSPAN14 lack of function with clinicopathological features of NSCLC patients, and to elucidate the role TSPAN14 might have in NSCLC progression. TSPAN14 expression was lower in tumor cells than non-tumor cells in NSCLC patients’ samples. The decreased gene expression was correlated with a low survival rate of patients and was more frequent in patients with aggressive, invasive tumor types. Additionally, the role of decreased TSPAN14 expression in the metastatic potential of cancer cells was confirmed in NSCLC cell lines. The highly invasive NSCLC cell line (NCI-H661) had the lowest TSPAN14 gene and protein expression, whereas the NSCLC cell line with the highest TSPAN14 expression (NCI-H460) had no significant metastatic potential. Finally, silencing of TSPAN14 in these non-metastatic cancer cells caused an increased expression of matrix-degrading enzymes MMP-2 and MMP-9, followed by an elevated capacity of cancer cells to degrade gelatin. The results of this study propose TSPAN14 expression as an indicator of NSCLC metastatic potential and progression. Full article
