Evaluation of the anticancer and anti-metastasis effects of novel synthetic sodium channel blockers in prostate cancer cells in vitro and in vivo

The Prostate

Abstract

Voltage-gated sodium channels (VGSCs) are involved in several cellular processes related to cancer cell growth and metastasis, including adhesion, proliferation, apoptosis, migration, and invasion. We here in investigated the effects of S0154 and S0161, two novel synthetic sodium channel blockers (SCBs), on human prostate cancer cells (PC3, DU145, and LnCaP) and a prostate cancer xenograft model. The MTT assay was used to assess the anticancer effects of SCBs in PC3, DU145, and LnCaP cells. Sodium indicator and glucose uptake assays were used to determine the effects of S0154 and S0161 in PC3 cells. The impact of these SCBs on the proliferation, cell cycle, apoptosis, migration, and invasion of PC3 cells were determined using a CFDA-SE cell proliferation assay, cell cycle assay, annexin V-FITC apoptosis assay, transwell cell invasion assay, and wound-healing assay, respectively. The protein expression levels of Nav1.6, Nav1.7, CDK1, cyclin B1, MMP2, MMP9 in PC3 cells were analysis by Western blotting. The in vivo anticancer activity was evaluated using a PC3 xenograft model in nude mice. S0154 and S0161 both showed anticancer and anti-metastatic effects against prostate cancer cells and significantly inhibited cell viability, w...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Cell Migration in Cancer and Metastasis

Migration of cancer cells into surrounding tissue and the vasculature is an initial step in tumor metastasis. Discover the latest research on cell migration in cancer and metastasis here.
