Summary of "An OMICS-based study of the role of C3dg in keratinocytes: RNA sequencing, antibody-chip array, and bioinformatics approaches."

Previously, we have identified the C3dg protein as an important player in the pathogenesis of atopic dermatitis (AD). In this study, we aimed to identify critical factors associated with C3dg in human keratinocytes based on high-throughput screening (HTS) approaches. We overexpressed C3dg in HaCaT human keratinocytes and conducted serial HTS studies, including RNA sequencing analysis integrated with antibody-chip arrays and implementation of bioinformatics algorithms (PPI mappings). Cumulatively, these approaches identified several novel C3dg-associated genes and proteins that are thought to be significantly involved in skin diseases including AD. These novel genes and proteins included LPA, PROZ, BLK, CLDN11, and FGF22, which are believed to play important roles in C3dg-associated skin functions in keratinocytes, as well as genes related to the two important pathways of systemic lupus erythematosus and Staphylococcus aureus infection. In particular, FGF22 is a unique gene that was detected and validated in all methods applied in this study. By integrating the datasets obtained from these HTS studies and utilizing the strengths of each method, we obtained new insights into the functional role of C3dg in keratinocytes. The approach used here contributes to clinical understanding of C3dg-associated applications and may also be applicable to treatment of AD.

Medical and Biotech [MESH] Definitions

Serologic tests based on inactivation of complement by the antigen-antibody complex (stage 1). Binding of free complement can be visualized by addition of a second antigen-antibody system such as red cells and appropriate red cell antibody (hemolysin) requiring complement for its completion (stage 2). Failure of the red cells to lyse indicates that a specific antigen-antibody reaction has taken place in stage 1. If red cells lyse, free complement is present indicating no antigen-antibody reaction occurred in stage 1.

A secreted matrix metalloproteinase that may play a role in matrix degradation during WOUND HEALING. It is expressed at high levels by KERATINOCYTES, suggesting its role in keratinocyte migration.

Those manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.

A 302-amino-acid fragment in the alpha chain (672-1663) of C3b. It is generated when C3b is inactivated (iC3b) and its alpha chain is cleaved by COMPLEMENT FACTOR I into C3c, and C3dg (955-1303) in the presence COMPLEMENT FACTOR H. Serum proteases further degrade C3dg into C3d (1002-1303) and C3g (955-1001).

Molecular sites on or in B-lymphocytes, follicular dendritic cells, lymphoid cells, and epithelial cells that recognize and combine with COMPLEMENT C3D. Human complement receptor 2 (CR2) serves as a receptor for both C3dg and the gp350/220 glycoprotein of HERPESVIRUS 4, HUMAN, and binds the monoclonal antibody OKB7, which blocks binding of both ligands to the receptor.
