Abstract

Prostate cancer (PCa) is the second leading cause of cancer‑related mortality among American males. Studies suggest that cigarette smoking is associated with the progression of PCa; however, the molecular mechanisms underlying this process have not been extensively investigated. PCa progression is characterized by increased cell migration and alterations in extracellular matrix (ECM)‑ and cell adhesion molecule (CAM)‑related gene expression. In the present study, the influence of cigarette smoke medium (SM) on cell migration and on the expression of ECM‑ and CAM‑related genes in PC3 prostate adenocarcinoma cells was investigated. According to a wound‑healing assay, SM treatment promoted PC3 cell migration. RNA expression levels from SM‑treated and control cells were analyzed using a polymerase chain reaction (PCR) array. Of 84 genes analyzed, 27.38% (23/84) exhibited a ≥2‑fold change in threshold cycle in PC3 cells following 0.5% SM treatment. Functional gene grouping analysis demonstrated that SM treatment modulated the RNA transcription of approximately 18.4% of CAMs and 33.93% of ECM‑related genes. Quantitative PCR analysis showed that SM treatment led to a significant decrease in transcription levels of the following genes:...Continue Reading

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.

Biophysics of Adhesion

Alterations in cell adhesion can disrupt important cellular processes and lead to a variety of diseases, including cancer and arthritis. It is also essential for infectious organisms, such as bacteria or viruses, to cause diseases. Understanding the biophysics of cell adhesion can help understand these diseases. Discover the latest research on the biophysics of adhesion here.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.

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.
