Abstract

Family with sequence similarity 83 member A (FAM83A) is a member of the FAM83 family and is proven to have oncogenic properties in several cancers. However, the mechanisms of FAM83A in human cervical cancer (CC) progression are unknown. Here, we found that FAM83A is highly expressed in CC tissues and cell lines through western blot and qRT-PCR. We utilized GEO datasets to assess FAM83A expression in CC in comparison to the normal cervical tissue (NCT) (GSE6791), and similarly, in lymph node positive CC compared to the lymph node negative CC (GSE26511). Immunohistochemistry (IHC) was used to quantify FAM83A expression in 20 NCT and 105 CC patient samples. FAM83A expression is upregulated in early-stage CC and correlates with aggressive clinicopathologic features. Moreover, both our hospital's and TCGA datasets revealed that patients of early-stage CC with higher FAM83A expression had a poorer prognosis. Subsequently, CCK-8 and transwell assays verified that FAM83A promotes proliferation, migration, and invasion of CC cells. Additionally, Gene Set Enrichment Analysis (GSEA) revealed that FAM83A is not only involved in cell development, differentiation, and proliferation but is also correlated with cell junction assembly and cell ...Continue Reading

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

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.

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.
