Abstract:
The purpose of this study was three fold: (1) to reveal the implications of Wnt5A for cytokine and chemokine production by human ovarian cancer cell line SKOV-3 cells, (2) to determine the influence of Wnt5A on chemotactic SKOV-3 cell migration, and (3) to assess the effect of inflammatory mediators on Wnt5A expression levels and to describe its underlying molecular mechanisms. A cytokine array was performed using a conditioned medium harvested from SKOV-3 cells transfected with specific siRNAs against Wnt5A or with scrambled siRNA and a transfection reagent alone as negative controls for 48 h. Chemotactic cell migration was performed using transwells. Inflammation-induced Wnt5A expression was determined by treating cells with recombinant human (rh) IL-1β, IFNβ, or TNFα alone or in combination with STAT3 and NF-κB inhibitors for different time durations. The cytokine array showed the suppression of GCSF, GM-CSF, IL-1α, IL-2, IL-13, and MCP-3 production, whereas cell RANTES and IL-7 showed increased levels in Wnt5A knock-down cells compared with those in controls. Chemotactic migration decreased significantly when the conditioned medium from Wnt5A knock-down cells was applied to the upper chamber of the transwell. Compared with the control, there were 30-fold and five-fold increases in Wnt5A mRNA levels in cells treated, with rhIL-1β and rhIFNβ, respectively after 8 h (P < 0.001). Compared with the control, TNF-α had a 1.8-fold increased levels of Wnt5A mRNA after 4 h (P < 0.01). Both NF-κB and STAT3 inhibitors decreased inflammation-induced Wnt5A expression. This study revealed a previously unrecognized immunomodulatory role of endogenous Wnt5A in ovarian cancer cells, which could further influence chemotactic cell migration.
Insights
This study reveals that Wnt5A influences cytokine production and cell migration in ovarian cancer. Inflammatory mediators increase Wnt5A expression, highlighting its immunomodulatory role in cancer.
Area of Science:
- Oncology
- Immunology
- Molecular Biology
Background:
- Wnt5A is implicated in various cancers, but its specific role in ovarian cancer's immune microenvironment and cell migration remains unclear.
- Understanding the interplay between Wnt5A, cytokines, and inflammatory pathways is crucial for developing targeted ovarian cancer therapies.
Purpose of the Study:
- To investigate the role of Wnt5A in cytokine/chemokine production by SKOV-3 ovarian cancer cells.
- To determine Wnt5A's influence on SKOV-3 cell chemotactic migration.
- To assess how inflammatory mediators affect Wnt5A expression and its regulatory mechanisms.
Main Methods:
- Cytokine array analysis of conditioned media from Wnt5A-knockdown SKOV-3 cells.
- Transwell assays to evaluate chemotactic cell migration.
- Treatment of cells with recombinant human interleukins (IL-1β, IFNβ, TNFα) and pathway inhibitors (STAT3, NF-κB).
Main Results:
- Wnt5A knockdown altered cytokine profiles, suppressing GCSF, GM-CSF, IL-1α, IL-2, IL-13, MCP-3, and increasing RANTES and IL-7.
- Reduced Wnt5A levels significantly decreased SKOV-3 cell chemotactic migration.
- Inflammatory mediators (IL-1β, IFNβ, TNFα) markedly increased Wnt5A mRNA expression, an effect modulated by NF-κB and STAT3 inhibitors.
Conclusions:
- Endogenous Wnt5A plays a significant immunomodulatory role in ovarian cancer cells.
- Wnt5A expression is upregulated by inflammatory signals via NF-κB and STAT3 pathways.
- Wnt5A may influence ovarian cancer progression through its effects on cytokine production and cell migration.
